A. General Antitrust Principles for Collective Action among Competitors

Antitrust laws have been traditionally suspicious about collaborations among competitors. Two main concerns are associated with competitor collaborations. The first is that cooperation may result in a cartel, where companies would discuss and exchange sensitive commercial information and agree on prices, output, quality, or innovation.Footnote ¹⁶ The second concern is that collaboration among competitors may increase collective market power and harm competition by increasing the ability and incentive of companies to raise prices above competitive levels or reduce output.

On the other hand, in some instances, cooperation among competitors may lead to pro-competitive benefits. Competitor collaboration may enable companies to offer new or cheaper products or services. The key is the combination of complementary activities, skills, or assets.Footnote ¹⁷ For instance, companies may combine their complementary research and development activities to produce new and improved products or combine complementary assets and skills to achieve economies of scale or scope. In contrast, the combination of substitutes will normally raise antitrust concerns.Footnote ¹⁸

Competitor collaborations are regulated by special antitrust guidelines of the European Commission in the European Union and the Department of Justice (DOJ) and the Federal Trade Commission (FTC) in the United States. Guidelines provide a general “safe harbor” or “safety zone” for agreements that are not hidden cartels and do not exceed a certain market share threshold. In the United States, a safety zone is established for such agreements among competitors, which do not collectively constitute more than 20% of the relevant market,Footnote ¹⁹ while in the European Union, the collective market share threshold is 15%.Footnote ²⁰ Additionally, there are special rules for assessing specific types of competitor collaborations, such as joint research and development, specialization, production, purchasing, commercialization, and standardization agreements.

The same rules in principle apply to both seller and buyer collaboration. However, seller cooperation is regulated more extensively, as it may include a broad spectrum of activities from joint R&D production to joint commercialization of products or services. Buyer collaboration covers joint purchasing, enabling buyers to negotiate better terms and conditions with sellers, leading to lower prices for consumers. The negative aspects of buyer collaboration may, in contrast, be felt by consumers or purchasers. Suppose buyer collaboration results in significant buyer power. In that case, buyers may decide not to pass on lower purchase prices to final consumers or collectively reduce the purchase price below the competitive level, harming sellers and reducing their incentives to innovate and, as a result, lowering the quality or output supplied by sellers.Footnote ²¹

B. Collective Action and SEP Licensing

Competitor collaboration exists in relation to SEP licensing as well. To date, we have largely seen collaboration on the seller side, where SEP owners form patent pools to jointly license SEPs to third parties. Antitrust authorities have adopted specialized rules for assessing the formation of patent pools and licensing-out of SEPs from a patent pool to third parties.Footnote ²² In contrast, LNGs for implementers are a new phenomenon, and there are currently no specialized rules for their assessment. Thus, general rules on assessing horizontal joint purchasing agreements could be used by way of analogy.

Pools and joint purchasing agreements share the same antitrust concerns. The main risk is that the aggregation of substitute products or services would constitute a price-fixing cartel and amount to a “per se” restriction (US) or a restriction of competition “by object” (EU). Additionally, horizontal cooperation among sellers or buyers risks exchanging confidential business information that may lead to direct or indirect collusion and cartelization on downstream product markets and upstream technology markets. The increased market power of such horizontal cooperation is another concern, which may lead to foreclosure of alternative technologies or harm to sellers manifesting in reduced innovation and product quality. Table 7.1 summarizes antitrust-related concerns of patent pools and horizontal joint purchasing agreements.

That said, antitrust authorities have produced guidelines for assessing joint purchasing agreements and have identified conditions when such competitor collaborations would not raise antitrust concerns. The rules for patent pools are much more elaborate than for joint purchasing agreements. There may be several reasons for such differentiated treatment. Joint purchasing agreements are primarily associated with the procurement of physical goods and services, while patent pools relate to the joint selling of technology (that is, intangible assets). Guidelines for joint purchasing agreements rely on market share thresholds to control the potentially negative effects of the increased market power of its members. On the other hand, patent pools are more efficient when they aggregate as much of the selling side of the market as possible. Thus, safeguards are focused not on the market share thresholds of pool members, but on mechanisms to control and negate the market power of a pool, for example, by only allowing the pooling of complementary patents, the freedom to license outside of the pool, and FRAND licensing terms for pooled patents.

Table 7.2 provides an overview of current antitrust safe harbors related to patent pools and joint purchasing agreements.

Considering that LNGs are a new phenomenon consisting of buyer collaboration in technology markets, some antitrust principles for LNGs could be borrowed both from antitrust safeguards related to joint purchasing agreements and from those related to patent pools.

A. Implications for LNGs

Now turning to LNGs, various questions may be raised when considering how the Huawei–ZTE negotiation framework should be applied to LNGs or, stated differently, how LNGs should conduct licensing negotiations in line with this framework. The different aspects of applying the Huawei–ZTE negotiation framework to LNGs will be addressed in the remainder of this section, following the subsequent steps of the framework. For this purpose, it is assumed that the LNG has been established so that it can be considered as lawfully representing its members in any interaction with the SEP licensor.

If the SEP licensor notifies the LNG in writing of alleged infringement of its SEPs by LNG members, it seems reasonable that the SEP licensor must only specify the category of products considered to be infringing and does not have to indicate at least one specific product of each LNG member. This category of products is also what creates the common interest of the members in having this SEP licensing matter addressed through the LNG.

Another interesting aspect to consider is whether the SEP licensor is entitled to exclude one (or more) members of the LNG for purposes of resolving a particular infringement dispute, because it prefers to have bilateral negotiations with this member. This may be the case if, for example, the SEP licensor and that member have multiple overlapping business activities and the SEP licensor wants to enter into negotiations with that member covering a broader scope than the specific products for which the LNG will negotiate licenses. It may also be the case that the SEP licensor and the member already have a license agreement in place covering part of the SEPs it is offering to license to the LNG. This is the mirror situation of a scenario in which a patent pool approaches an implementer for a pool license, and the implementer prefers to have bilateral negotiations with licensors in the pool, because, for example, the implementer already has a (cross-) license agreement in place with one or more pool licensors and covering the products licensed by the pool. A licensor cannot refuse to enter into bilateral license negotiations with an implementer that makes such a request. Following the same approach for LNGs, an LNG member should not be allowed to refuse a request for bilateral negotiations from a SEP licensor.

In response to the written notification of the SEP licensor, the LNG must communicate that its members are willing to enter into a license agreement on FRAND terms with the SEP holder. This willingness should be unconditional in the sense that this willingness should not depend on whether, and the extent to which, individual members accept the outcome of the negotiations between the LNG and the SEP licensor. Negotiations between a SEP licensor and an LNG are likely to fail without a firm commitment by members of the LNG to accept the outcome of the negotiations and enter into a license agreement with the SEP licensor on that basis. Suppose the LNG and the SEP licensors reach an agreement on the FRAND terms of a license, and the LNG members are free to accept or decline this outcome and thus can freely determine whether or not to enter into a license agreement on these terms with the SEP holder. In that case, the SEP holder may find it unattractive to enter into license negotiations with the LNG at all. It will create an incentive for at least some LNG members to request bilateral negotiations with the SEP licensor and take the outcome of the negotiations with the LNG as the starting point for their own bilateral negotiations, hoping to negotiate separately even better licensing terms. The freedom to decline the agreed outcome of the negotiations between the SEP holder and the LNG may also be used as part of a holdout strategy by an implementer, who can defer paying royalties that licensed LNG members are already paying. Members should commit to entering into a license agreement with the SEP holder if the LNG and the SEP holder have reached an agreement approved by the members. This aspect will be addressed in greater detail when discussing the governance of LNGs in Section IV.

A key factor in the success of LNGs relies on members’ commitment to enter into a license agreement with the SEP licensor based on the approved outcome of negotiations between the LNG and the SEP licensor. Suppose, despite such a commitment, a particular member does not enter into a license agreement with the licensor within a reasonable period after the agreement is reached. In that case, it seems reasonable that this member should be deemed an unwilling licensee and the licensor should be entitled to seek an injunction against the implementer without being accused of misusing a dominant position. If the SEP holder initiates litigation against a recalcitrant LNG member and the member, in the face of a likely injunction, elects to accept the FRAND terms negotiated with the LNG, it seems unfair that the implementer would still be entitled to a license under the same FRAND terms. Even if a court finds that the implementer is still entitled to a FRAND license, the implementer should be required to pay a penalty on top of the agreed FRAND terms (for example, in the form of a higher royalty for infringing sales made prior to entering into the license agreement with the SEP licensor).

Suppose a SEP licensor submits a FRAND license offer specifying the royalty and giving the reasons why it considers this royalty to be FRAND. In that case, the LNG must diligently respond to that offer without undue delay. If the LNG does not accept the license offer, it should timely make a FRAND counteroffer in writing. In bilateral negotiations, courts have held that a response time of three months is not timely.Footnote ³⁰ In contrast, in another case, a five-month period was not regarded as timely.Footnote ³¹ In the case of LNGs, courts may take into consideration that it may take more time for the members of an LNG to agree internally and deliver a counteroffer, but even in this case, a court may find that making a counteroffer after more than five months is not timely.

If that situation would arise, would all LNG members be considered unwilling licensees? It is difficult to predict how a court would determine this point. Nonetheless, the mere fact that an LNG is negotiating with a SEP licensor does not release that LNG from its obligation to provide a timely FRAND counteroffer after having rejected a licensor’s offer. Additionally, there may be a different response time that a licensor is willing to accept before taking legal action. The SEP licensor may prefer the prospect of getting all members of an LNG licensed through a single negotiation over litigation, and may therefore be willing to accept a longer period for the LNG to respond to its FRAND offer than would be the case in a bilateral negotiation.

The same question arises if, in response to an offer by a SEP licensor, the LNG responds with a very low counteroffer that is clearly non-FRAND. Will all LNG members be considered unwilling licensees and potentially risk an injunction if the SEP licensor commences infringement actions against individual LNG members? In this case, all LNG members should again be considered unwilling licensees. Under the Huawei–ZTE negotiation framework, a group of licensees should not behave and be treated differently than any individual licensee.

Moreover, suppose the LNG does not negotiate in good faith by a delayed response to the SEP holder’s offer and then making a clear non-FRAND counteroffer. In that case, the SEP licensor may accuse the LNG members of engaging in a group holdout, which may be the basis for an antitrust complaint by the SEP licensor.

Under the Huawei–ZTE negotiation framework, if the SEP licensor rejects a counteroffer from an implementer, the implementer must provide a bank guarantee or put in escrow an amount for the royalties on its past sales based on the rate in its counteroffer. Applied to the LNG context, this implies that the LNG must provide a collective bank guarantee for all its members or put an amount in escrow for the royalties on the collective past sales of all its members, or alternatively, each individual member would have to provide a bank guarantee or put money into an escrow account for the royalties on its past sales. In both cases, the members would have to provide an accounting of these past sales. In the first case, it may be difficult for the LNG to get a bank guarantee, since it may not have funds to support this guarantee, and it will not be an easy task to ensure that all members place the appropriate amounts in escrow.

In negotiating a SEP license, an LNG must follow the Huawei–ZTE negotiation framework in the same manner as an individual company. In theory, since LNGs are likely formed with the goal of reducing transaction costs for their members, to negotiate better FRAND royalty terms than each individual member could negotiate, and to level the playing field among their members, they should be incentivized to negotiate in good faith, especially if its behavior could result in all its members being deemed unwilling licensees, which would entitle the SEP holder to seek injunctive relief against LNG members. This accountability should also encourage the LNG to timely respond to written notifications (infringement letters and/or FRAND offers).

A. A Safe Harbor for LNGs

As discussed in Section II.B, a set of guidelines similar to those that have been developed for patent pools is needed to create a safe harbor for LNGs. Currently, no request for review of an LNG for licensing purposes has been submitted to the DOJ or EC (or other competition authority). Nevertheless, it is possible to identify a number of conditions that LNGs must satisfy to avoid likely conflicts with antitrust laws.

One key question is whether the members of an LNG should be allowed to have a collective market share that could enable the LNG to exercise market power. Generally, a collective market share of less than 15–20% is considered acceptable in the case of other types of collaborative buying groups.Footnote ³² However, greater market shares may be deemed pro-competitive given the potential to reduce transaction costs and limit patent holdout, especially as the LNG is bound to a FRAND rate and, in Europe, the negotiation guidelines of Huawei–ZTE. However, as the market share of an LNG increases, additional antitrust scrutiny is justified, concerning both the SEP licensing market and the possibility for collusion among LNG members in the downstream product market. Thus, it will likely be necessary to assess the maximum collective market share for LNGs on a case-by-case basis across different industry verticals. Taking the smartphone market as an example, an LNG including Apple, Samsung, Xiaomi, Oppo, and Vivo with roughly a 70% collective market share would be heavily scrutinized. On the other hand, companies in the tail of the smartphone market, each of which has less than a few percent market share, should be allowed to form an LNG without significant inquiry, since they do not have a strong market position, do not collectively hold significant market power, and the LNG will have better negotiation capabilities than each individual member. If successful, the LNG will not harm competition or innovation in the smartphone market.

LNGs will tend to be more successful if members are situated at approximately the same level of the value chain. In the example just discussed earlier, the smaller companies in the tail of the market are all similarly situated. This would likely help solve the collective action problem (that is, patent holdout) introduced in Section I by facilitating a level playing field among similarly situated competitors. It would be more difficult if the LNG has members operating at different levels in a value chain that make and sell different products (components versus end products). In that situation, conflicting interests among LNG members may make it unattractive for a SEP licensor to start licensing discussions with the LNG.

LNG members could be allowed to share information within the group about the essentiality, validity, and infringement of the relevant SEPs. However, they should not share any opinions or conclusions regarding this information, as this may be considered collusion. On the other hand, the LNG could be allowed to act on behalf of its members by seeking outside counsel’s opinion regarding certain matters, since this would likely reduce the costs borne by each member, consistent with a key purpose of an LNG.

During their meetings, LNG members should not be allowed to discuss prices of products, profit margins, or market shares. The same principle applies in meetings of SEP licensors in the context of patent pools. To ensure that this rule is upheld, it would be advisable for an antitrust lawyer to attend all their meetings and remind the participants at the start of each meeting about the members’ duties to operate in accordance with the antitrust laws and about the subjects they must not discuss. This external counsel should also intervene if any member raises a topic that should not be addressed.

LNG members should be allowed to disclose their position on royalty rates only with the LNG representative negotiating with the SEP licensor and not between LNG members themselves. This alleviates the concerns about possible coordination of royalties by LNG members, as only the LNG negotiator will have all the information on royalties collected from members. And only the LNG negotiator needs to know the pricing position of all LNG members in order to attempt to arrive at the most acceptable royalty level in negotiations with SEP owners.

Moreover, it should be realized that the LNG and the SEP licensor are bound by the Huawei–ZTE negotiation framework, which reduces the risk that the LNG will be able to negotiate or dictate a sub-FRAND royalty. Concluding licenses with a group of companies in a single negotiation through an LNG reduces the cost of licensing for a SEP licensor. The SEP licensor may share part of these benefits with the LNG members by accepting a lower royalty, but in doing so, the SEP licensor will still have to consider the nondiscrimination prong of its FRAND obligations toward other similarly situated licensees outside the LNG.

These proposed steps for conducting negotiations between SEP licensors and LNGs and other pertinent steps should be formulated into guidelines that aim to create a safe harbor for LNGs and which, if followed, would greatly reduce the most problematic anticompetitive risks. As mentioned, LNGs seem particularly interesting for similarly situated companies in the tail of markets, which collectively do not possess a market share that gives them market power. Given the increasing use of connectivity standards in various IoT verticals and the increasing number of companies that require licenses under SEPs from licensors for these standards for a wide variety of products, LNGs become increasingly attractive for both SEP licensors and similarly situated implementers given lower transaction costs and the opportunity for smaller implementers to secure more competitive royalty rates and enter the product market on a level playing field. This is even more relevant, as implementers in emerging IoT verticals may be less familiar with standards and SEP licensing than implementers in the telecom sector.

B. Governance of LNGs

In the previous sections, the organization, operation, and decision-making of an LNG have not been addressed. However, the governance of an LNG is one of the decisive elements in determining its success. Member selection, member commitments to enter into license agreements with a SEP licensor(s) on agreed terms, voting rules, and providing clear mandates for the negotiators are principal elements that must be included in the governance of LNGs. This section will describe the various governance elements of an LNG in more detail.

An LNG can be set up in different ways, from purely formal to informal. LNG members can establish a legal entity specifically for this purpose, which is jointly controlled by the members. This may be attractive in a setting where the members are already members of a professional organization or association in their industry and where they will use this entity for handling negotiations with other SEP licensors for the same and other standards that they may use in their products. They can hire one or more licensing experts and other staff required to do the actual negotiations with a SEP licensor. The LNG members need to agree among themselves and with the legal licensing entity what mandate is given to the licensing entity and how that entity should interact with the LNG members.

Alternatively, the LNG members could simply contract several experts or a law firm to handle the negotiations on behalf of the LNG members on a project basis. In this case, the relationship between LNG members and the contractor must be formalized so that the negotiators have a clear mandate. In a more loosely controlled arrangement, the members of an LNG could elect a number of their representatives as the negotiators on behalf of the members and potentially hire a law firm or licensing experts to support them in the negotiations with the SEP licensor. Whatever the setup of the actual group or entity for handling the negotiations, it is important that negotiators have a clear mandate from the LNG. In particular, the process of communicating with the LNG during the negotiations should be clear and fully transparent, as it may otherwise frustrate not only the relationship between the LNG entity and LNG members but also the relationship between the entity and the SEP licensor(s).

When handling a specific SEP licensing opportunity, relevant companies need to determine individually whether they want to become members of the LNG or wish to opt out, because they prefer to negotiate with the relevant SEP licensor(s) bilaterally. As discussed in Section III, giving members the opportunity to opt out once the results of the LNG negotiations are known incentivizes individual members to use the outcome of the negotiations as a starting point for separate bilateral negotiations, aiming to get a better deal for themselves. This could lead to a disparity in royalty rates among LNG members. As a member of an LNG, a company enjoys the benefits of lowering its transaction costs and potentially obtaining better FRAND terms than it would be able to negotiate itself. However, it also runs a risk that it will not be satisfied with the terms negotiated with the SEP licensor and approved by the LNG members. Each company should assess this risk and determine whether it wants to opt out at the beginning of the negotiations with the SEP licensor. Also, allowing LNG members to opt out at the end of the process could induce certain implementers to hold out as long as possible based on the expectation that the SEP licensor may not be willing to litigate against an individual member, since the litigation cost may be higher than the revenues that can be collected from that implementer. Therefore, to prevent use of the LNG as a vehicle for holdout, the LNG should at the start of the process request that members commit to the agreed outcome of the negotiations and enter into a license with the SEP licensor within a predetermined period after approval of the result of the negotiations. In this way, SEP implementers can either negotiate collectively in good faith or opt out from the beginning, where the latter is simply the status quo.

Suppose an LNG would include companies that operate at different levels of a value chain, for example, members who operate at the downstream end product level and other members who operate at the component level. In that case, the LNG should be formed only by members operating at the same level in the value chain. The appropriate membership for the LNG will depend on the level in the value chain that the SEP holder targets for its licensing program. This should be clear from the assertion letter from the SEP licensor, in which it should indicate the devices alleged to infringe its SEPs. If LNG members occupy different levels of the value chain, the likelihood of a successful outcome to the negotiations is lower.

LNG members will also need to conclude a nondisclosure agreement to keep the information regarding the negotiations confidential and not disclose it to others both inside or outside the LNG. It is recommended that the LNG involves an outside counsel who can advise the LNG members on the obligations of the LNG to operate in line with the Huawei–ZTE negotiation framework and also to remind members at every meeting that members should not discuss prices, profits, market shares, and other information that would run afoul of antitrust guidelines. Moreover, this counsel should guide the members on what types of information they can share concerning the essentiality, validity, and infringement of the SEPs asserted by the licensor. Again, the goal is to reduce transaction costs while managing the risk of antitrust behavior.

Another important governance aspect of an LNG is how decisions are taken and thus what voting rules and procedures are put in place for various categories of topics that the LNG members may have to decide upon. Requiring full consensus is not recommended, as this gives individual members a veto right to block important proposals that are acceptable to all other members. Voting by a supermajority on major issues may provide a better approach for LNGs to facilitate broad market impact in the shortest timeframe (that is, reducing patent holdout).

Once the SEP licensor has provided the LNG with its FRAND offer, the LNG members will need to conduct a consultative process with their representatives concerning the terms of the counteroffer to the licensor. This will require taking into account all information regarding the licensor’s SEP portfolio, including any opinions from outside counsel. The negotiators must be given clear, approved instructions (in accordance with the voting rules) about the counteroffer and a clear mandate for the subsequent negotiations with the SEP licensor that may ensue.

Suppose the negotiators can reach an agreement with the SEP licensor about the FRAND terms for a SEP license, and the LNG members approve the results according to their voting rules. In that case, each LNG member should enter into a license agreement with the SEP licensor within a predetermined time (for example, within six months in accordance with their commitment at the start of the process). It is in the interest of all LNG members that every member honors its licensing commitment, which creates a level playing field among the LNG members and avoids the collective action problem that can induce patent holdout. Any LNG who fails to enter into a license on a timely basis may be deemed an unwilling licensee and is therefore running the risk that the SEP licensor may seek an injunction against that member. This incentive structure is critical to maintaining the level of accountability and commitment required to make an LNG a viable SEP licensing mechanism.

Having a clear and transparent governance structure will enhance the ability of an LNG to achieve its goals of reducing members’ transaction costs and obtaining better FRAND licensing terms than each member can negotiate individually. Additionally, implementing proper rules of governance can ensure that LNG members act in good faith toward both licensors and LNG members and, as a result, overcome the collective action problem that can result in systemic holdout.

C. Example of an LNG

Although LNGs exist in other fields, such as joint purchasing groups for physical goods, LNGs in the field of licensing are mostly uncharted waters, although some precursor organizations and activities do exist. For example, defensive aggregators, such as RPX and AST, aggregate buyers of patents to facilitate licensing and reduce transaction costs, which is somewhat similar to the proposed role of LNGs. The recent syndication deal between RPX and Sisvel regarding SEPs for the Wi-Fi standard illustrates the transaction cost savings obtained by “pooling” both buyers and sellers in a single transaction as shown earlier in Figure 7.1.Footnote ³³ Additionally, patent licensing platforms such as Avanci exemplify how linking licensors and licensees through a single platform can potentially enhance the efficiency of SEP licensing markets.Footnote ³⁴ One-Blue is possibly the best example of a successful negotiation between groups of SEP licensors and licensees. In this section, the experience with an actual LNG in the One-Blue context will be discussed further.

The SEP licensor, in this case, was the One-Blue patent pool, which included a large majority of all the licensors holding SEPs for the Blu-ray standard and holding a significant part of the relevant SEPs for the standard for Blu-ray Disc™ products.Footnote ³⁵ The Blu-ray standard is the successor to the DVD standard, offering consumers higher video quality with interactive features. Blu-ray players and recorders are backward-compatible with the various DVD and CD playback and recordable/rewritable standards. For the previous standards, joint licensing programs had been formed on a standard-by-standard basis, which required securing licenses from one or more patent pools, as well as from several individual licensors. Had this approach been followed for the Blu-ray Disc standards, the number of licenses necessary to manufacture and sell Blu-ray Disc players and recorders would have been so large that it would have discouraged manufacturers from developing Blu-ray-compatible products. To promote widespread use of this standard, the three originators of this standard, Philips, Sony, and Panasonic, developed the concept of a product pool or “pool of pools” for Blu-ray products, where all the SEPs for the Blu-ray standards and the backward-compatible standards were included in one licensing package offered to potential licensees. This provided a one-stop-shop licensing mechanism that yielded a reduced aggregate royalty rate compared to the sum of the royalties that would have been paid if each standard had been licensed separately.

Based on experiences in licensing older-generation formats, it was known that licensing manufacturers in one particular major country had taken longer and had required more efforts than in many other countries. Since the purpose was to stimulate and develop the market for Blu-ray products as quickly as possible, a different approach was chosen. While the basic framework of the patent pool and its licensing program were being established, licensing discussions were commenced with the industry association in that country for the relevant type of consumer audio/video products. All the relevant manufacturers were members of this industry association. Several meetings were held, in which the basics, including the royalty structure of the new licensing concept, were explained, questions were answered, and feedback on the various elements of the licensing program was sought, which were taken into account in finalizing the patent pool program.

After announcing the patent pool licensing program, meetings between the patent pool administrator and the industry association representing their member companies continued to discuss the collective licensing of these companies. Multiple meetings took place to discuss the benefits of reduced transaction costs for these members, including the elimination of the risk of ending up in costly litigation, the prospect of ensuring a level playing field among the association members, and the efforts that the pool would undertake to license other implementers of the Blu-ray standard. This holistic value proposition incentivized the industry association to agree with the patent pool administrator to advise their relevant members to sign a standard license agreement with the pool. To incentivize members to sign up with the patent pool within a six-month period, the industry association also agreed that any member not signing up in this period would not be given access to certain additional services provided by the association as long as they remained unlicensed.

Due to the close and constructive cooperation between the industry association acting as the representative of the relevant group of manufacturers (that is, as an LNG), it was possible for the patent pool to sign up a group of 15 midsize manufacturers within six months. Achieving the same result conventionally through bilateral negotiations may have taken years and required one or more litigations. This example demonstrates that licensing groups of implementers in a single licensing negotiation process through an LNG can offer significant benefits to both SEP licensors and implementers, not only reducing transaction costs but also eliminating holdout through collective action.

A. Validity Rates

Licensing negotiations tend to follow a rather fixed pattern. In the first phase, the implementer presents its arguments why one or more of the asserted SEPs are believed to be non-essential. In the second phase, the implementer makes arguments why one or more SEPs are believed to be invalid. As discussions about validity involve judgments about whether or not a patented invention is obvious, it might not be easy to reach agreement on validity. The objective of implementers is to try to undermine the SEP position of the licensor by advancing claims that the royalty offered by the licensor is too high and not FRAND. In cases where the parties are not able to reach an agreement and proceed to litigation, the implementer will in many cases contest the validity of the SEPs being asserted against it.

Since the introduction in the United States in 2012 of inter partes review (IPR),Footnote ¹⁴ implementers faced with SEP patent assertions have used IPRs in an effort to invalidate the SEPs. Today many large implementers file IPR petitions as a response to a SEP assertion letter while, at the same time, ensuring that they take those steps in line with the Huawei–ZTE negotiation framework and, as a result, are likely to be viewed as a willing licensee who is negotiating in good faith. In some cases, large implementers file multiple IPR petitions, which may place financial and resource pressure on the SEP licensor. This strategy may discourage smaller SEP licensors from asserting their SEP portfolios, which may have a negative impact on their investments in innovation and willingness to participate in standard-setting processes in the future.

Based on various reports, the PTAB invalidates about 65% of the challenged patent claims in accepted cases (in the term used by the PTAB, “instituted petitions”).Footnote ¹⁵ Also, courts in Germany have declared 33% of all litigated patents in the period 2018–2020 fully invalid and 41% partially invalid.Footnote ¹⁶ These rates are more or less in line with the results of opposition proceedings against European patents before the European Patent Office.Footnote ¹⁷ These figures apply to all patents and not only SEPs, but it can be assumed that invalidation rates for SEPs will not be lower than for non-SEPs. Any SEP invalidity determinations reached through these adjudicative processes will impact a licensor’s SEP position toward not only the implementer involved in each proceeding but also all other implementers. These invalidation rates show that implementers have a substantial likelihood of success in contesting the validity of SEP patent claims in litigation, IPRs, or oppositions. An implementer can use the risk of invalidation to try to secure better SEP royalty terms through settlement prior to adjudication. On the other hand, SEP licensors might already price into their royalty rates the likelihood that roughly half of their SEPs may be declared invalid in litigation, IPR, or oppositions.

It is not expected that this situation will change any time soon. As long as major patent offices continue to examine all patent applications with approximately the same degree of scrutiny, the percentage of invalidated claims of granted patents that are used in SEP licensing is not likely to change. Implementers will continue to contest the validity of asserted SEP patents, and SEP licensors will continue to be faced with invalidations of patents in their SEP portfolios offered for a license. Nonetheless, it still makes sense to consider mechanisms that may provide a reasonable estimate of whether the patent will be upheld or invalidated, quickly and easily, right at the beginning of negotiations.

B. In-Depth Prior Art Searches

SEP licensors could undertake in-depth prior art searches on their SEPs prior to submitting them for an essentiality check or even prior to starting to prepare claim charts. The quality of state-of-the-art semantic search engines, often with additional artificial intelligence/machine learning (AI/ML) functionalities, has improved in recent years, especially for application in the field of information and communication technologies. These engines could be used to conduct fast, low-cost full-text searches against patent databases without limitations on technical classes in the Cooperative Patent Classification (CPC) system or other classification systems. Companies offering these search engines as a commercial service are readily available. The searches may reveal relevant prior art that has not yet been considered in patent examination procedures. Based on this prior art, a patent holder could decide that the patent in its current form is not likely to stand a validity test in court (or in an IPR) and consequently that it hardly makes sense to spend money on having it checked for essentiality. Patent holders may also opt to use these search engines during the examination procedure and bring any relevant prior art to the attention of patent examiners so they can take this prior art into account when evaluating the patentability of the claimed inventions. If used pre-grant, these prior art searches would contribute to reducing the likelihood that SEPs will be declared invalid when scrutinized in court or in IPRs. The post-grant use of such searches would make it possible to predict the answer to this question with reasonable certainty. Both the pre-grant and the post-grant use may reduce litigation based on invalidity claims of litigated SEPs. However, if such prior art searches show no indication of invalidity, an implementer would still have the right to claim the invalidity of SEPs in court. Litigation costs considerable time and money for both parties, and, moreover, it may take years before a final decision is made about the validity of a SEP, and clarity is achieved not only for the parties involved in litigation but also for other potential licensees.

C. Validity Challenges

It is desirable to achieve the clarity described in the preceding section in an early phase of the development of a standard-compliant product market. This could be achieved if implementers could challenge the validity of asserted SEPs in an out-of-court challenge procedure before panels of independent patent experts. These panels could be selected from a pool of experienced and qualified patent experts certified by an independent body that facilitates and supervises these panels. This body could, for example, be the same body supervising the essentiality checks as described in Section III.

The challenge procedure should be relatively fast and inexpensive. It seems feasible that with a strict process where parties bring their arguments and counterarguments in a limited number of rebuttals, panels should be able to produce valid opinions in about six to seven months. This should also keep the cost relatively low and well below the average cost of IPRs, which are estimated between $300,000 and $600,000.Footnote ¹⁸

These panels would issue opinions about the likelihood that a patent will withstand a validity challenge when scrutinized in court (or in an IPR). They could not invalidate a patent, as this can only be done by a court. The parties could agree to accept the opinion of such a panel, or a party not accepting the opinion of a panel could elect to go to court. If an implementer went directly to court to claim invalidity without first using the faster and less expensive validity challenge panel and the patent’s validity is upheld in court, the implementer should be ordered to pay the licensor’s reasonable out-of-pocket costs. The same should apply to a SEP licensor who commences litigation without having completed the challenge procedure, provided the implementer initiated the challenge to the SEP’s validity in a timely manner. This would create an incentive for both licensors and implementers to use the validity challenge procedure before going to court. This would also counter any hold-up or hold-out strategies.

If the panels produce high-quality opinions and courts generally do not come to different conclusions, the parties will increasingly rely on such opinions and will tend not to bring such cases to court. This would reduce the number of litigations based on claims that asserted SEP patents are invalid.

A. Publishing Standard License Terms

Even when the SEP owners and the size of their SEP portfolios are known in the case of a particular standard, it is unlikely that implementers will approach the relevant licensors for their standard-compliant products. A SEP licensor will still have to identify the implementers that commercialize standard-compliant products using their SEPs and assert their SEPs against these implementers. This wait-and-see approach may mean that an implementer is approached by SEP licensors years after they started to commercialize standard-compliant products. Without information about the estimated aggregate royalty for these products, many (or even most) implementers would not take an estimated aggregate royalty into account in their business plans and would not make provisions for the royalties they will have to pay. In the meantime, these implementers may have considerable liability exposure to royalties owing on sales made prior to being approached by a SEP licensor. This liability exposure will increase even further, as licensing negotiations may also take considerable time (easily 18–36 months). Although SEP licensors are usually willing to give discounts on royalties for past-use sales, the outstanding past sales amount may create such a financial burden for the implementer that this may prolong negotiations even further.

The aforementioned situation could be avoided if licensors with confirmed SEPs make their standard license terms (or, alternatively, their standard license agreements) for a standard-compliant product publicly available through the relevant SDO, for example, ETSI. This could be done by recording those terms and conditions in the ETSI database or alternatively by showing a link to the website of the relevant SEP licensor where these terms and conditions are listed, which ensures that the latest terms and conditions are shown.

It should be appreciated that the standard license terms will apply only to specifically identified standard-compliant product(s). There may be different standard-compliant products within one application field – for example, infrastructure equipment and smartphones in the telecoms area, but also different products in various IoT verticals. A SEP licensor may publish different license terms for these different products since they may use different SEP families and the value that these patented technologies add to these products may be different. A SEP licensor does not need to publish the terms for all these different products at the same time. Rather, it could publish terms when the markets for the relevant compliant products start to develop.

B. Implementers Proactively Seeking Licenses

By publicly disclosing its standard terms for a license under its confirmed SEPs for specific standard-compliant products, the SEP licensor would not be required to take the initiative to approach an implementer and should be assumed to have fulfilled both the first step of asserting its SEPs against an implementer selling such products and the third step of making a FRAND offer for a SEP license for these products according to the Huawei–ZTE negotiating framework.

The licensor’s disclosure of its license terms should obligate the implementer to proactively seek a license from the SEP licensor, as required by the Huawei–ZTE negotiations framework. The implementer should fulfill the second step of this framework by expressing its willingness to take a license on FRAND terms and also should fulfill the fourth, fifth, and sixth steps, which obligate the implementer to respond diligently to the SEP offer without delay, to promptly make a counteroffer if it does not accept the published offer of the SEP licensor as being FRAND, and to provide security for the payment of past and future royalties based on its counteroffer, respectively. Moreover, an implementer would be required to take these steps prior to the commercialization of the relevant standard-compliant products.

This extension of the Huawei–ZTE negotiation framework will create incentives both for SEP licensors with true SEPs to publicly disclose their licensing terms and conditions before, or as early as possible after, the market for the relevant standard-compliant products starts to develop and for implementers to proactively seek licenses from such licensors prior to commercialization.

If implementers can access the published standard licensing terms of a SEP licensor, this will promote a more level playing field among implementers. Despite the nondiscrimination obligation under the FRAND undertaking, implementers have regularly expressed hesitancy to take licenses out of concerns that different terms may be offered to their competitors.

Under the extended negotiation framework, SEP licensors would be able to conclude licenses more rapidly and earlier in the commercialization process as compared to the current negotiation framework. When a licensor’s SEPs are confirmed to be true SEPs, it can bypass the usual negotiation phase of discussing with each potential licensee whether or not its SEPs are true SEPs, saving both licensors and implementers time and effort and shortening the time to negotiate license agreements. Moreover, when implementers proactively seek licenses, SEP licensors could negotiate licenses with implementers not only more rapidly but also at an earlier point in time, which will enable them to receive licensing revenues earlier than otherwise would be the case. SEP licensors would be faced with an increased workload by having to negotiate licenses with several implementers in a more condensed period of time. However, greater efficiency in the licensing process seems to be needed in any case in light of the increasing number of implementers due to the increasing use of connectivity standards in the various IoT verticals.

By having to proactively seek licenses from a SEP licensor with confirmed SEPs and published standard license terms, an implementer would also avoid payment of a substantial amount of royalties for past sales that could form a significant obstacle to reaching a SEP license agreement under the current negotiation framework. This scenario is likely to arise when, as described previously, implementers wait until a SEP licensor asserts its patents to start negotiations.

We emphasize that a SEP licensor would have the choice to determine whether or not it wishes to publicly disclose its license terms for its SEPs and for which products. If a SEP licensor declines to disclose its license terms, the current Huawei–ZTE negotiation framework would continue to apply. This means that a SEP licensor has to assert its SEPs against an implementer as a first step to start the negotiation process. Additionally, the implementer would only be obligated to proactively seek a license if the licensing terms are also published in a database of the relevant SDO.

If the SEP holder takes the steps described previously and an implementer either does not proactively seek a license or fails to make a substantiated FRAND-counteroffer in a timely manner, the SEP holder would be entitled to seek an injunction against the unwilling implementer.

If the license offered by the SEP holder relates to one component of a complex product incorporating many different technologies, including several standardized technologies, an injunction may be too harsh a penalty for the implementer, who may have already invested in the development and manufacture of this product. On the other hand, an injunction may be too weak a sanction if the implementer can avoid it by submitting a counteroffer in the course of litigation initiated by the SEP licensor. Therefore, it may be more appropriate in this case to impose a penalty in the form of increased royalties on the implementer’s past-use sales prior to entering into a license agreement. The size of this penalty should depend on the time elapsed between the implementer’s response and the licensor’s offer. This type of penalty is necessary to create sufficient incentives to induce the implementer to submit a counteroffer in a timely manner and present any other arguments it wishes to present against the assertions of the SEP licensor. In addition to this penalty, a SEP licensor may claim damages to the extent permitted under relevant national laws.

This sanction would also promote a more level playing field among implementers. If most and even all implementers seek to obtain a SEP license in a timely manner, they will also include the royalties in the calculation of the price of their product from the outset. Given an implementer’s exposure to increased royalties in the absence of a timely response to a published license offer from a licensor, implementers would incorporate the expected royalties in the price of their standard-compliant products.

To the same extent, this sanction would also counteract hold-out tactics. If the implementer fails to make a timely response to a standard license offer, then the increased royalty should apply to all sales made by the implementer until a license agreement is reached, either by settlement or judicial determination. Therefore, an implementer would have an incentive to respond in a timely manner to a standard license offer or, in the absence of such a response, to limit the prospective penalty by negotiating expeditiously a license agreement with the SEP holder.
