⁴ We deliberately avoid referring to “private Acts” throughout the remainder of this article. This is because eighteenth-century usage of the public/private act dichotomy does not map onto modern usage and many of the pieces of legislation with which we are concerned were in fact styled as public measures.

¹³ Bottomley, British Patent System, pp. 48–49. In this regard, Bottomley seeks to draw support from Mario Biagioli's work. Taking the US as his case study, Biagioli ties the transformation of patents from privileges into property rights to the demise of political absolutism and the rise of the modern political subject. He posits that the emergence of the specification and the decline in the importance of the assessment of utility were important stages in this process. There is, however, nothing in Biagioli's account to suggest this process would have been anything other than gradual in the context of a society such as England, where the transformation in the political system took place over a protracted period.

¹⁵ Providing the equivalent current value is complex. For example, if one takes this sum at 1800 (as representing more or less the mid-point in the system of parliamentary payments), commonly accepted methods of conversion produce a range of slightly more than £14,000,000 to considerably in excess of £800,000,000. For current purposes, however, the most useful comparator is that of equivalent “economic status” which in 2013 would equate to £206,800,000: <www.measuringworth.com>.

²⁷ See e.g. J. Mokyr, The Gifts of Athena: Historical Origins of the Knowledge Economy (Princeton 2005). Such claims are, however, controversial and within the rich and diverse literature on the Industrial Revolution we find other authors who argue that the drivers of industrial growth were quite different. To take but one example, for Hobsbawm the technological developments of the eighteenth century rested on the “application of simple ideas and devices, often of ideas available for centuries”. It was only once the UK had secured a vast market for its products in colonial territories by means of an aggressive military strategy that it made sense for entrepreneurs to invest in these technologies: E. Hobsbawm, Industry and Empire (Harmondsworth 1974), 60. Nevertheless, in contemporary accounts there seems to be a consensus that at least some attention needs to be given to the new ways in which technical information came to be shared and employed over the course of the eighteenth century.

However, whether foreign traders were actually denied access to Lombe's models is rather more difficult to say, since the conditions of public access to parts of the Tower only began to be standardised in 1729 and hence there may still have been the possibility of securing additional access through the payment of a gratuity to the relevant guard or official: ibid., at p. 98.

⁶⁶ More specifically, the dominant justification for patent protection is normally said to be that it provides inventors with an incentive to invest in new technologies, but disclosure is understood to offer an important subsidiary public benefit and is a precondition for protection in every case.

⁷⁵ Here it might be noted that something approaching the modern notion of public money had been established in political discourse by this time. This is clearly reflected in the debate around the size of the reward to be paid to Jenner. As rhetorical devices, notions of public money, public finances and parliamentary consent may have helped give a greater degree of legitimacy to the tax burden in the UK than in other countries such as France, where the tax burden was actually considerably lower.

⁸⁰ The emergence of modern modes of government that could nevertheless accommodate other paradigms is one that finds strong support in Weber's account of the development of the state. For Weber this was exemplified in the legal context by the persistence of “empirical justice” (which allows for ad hoc “practical valuations”) alongside a “rational” interpretation of law (that rests on “strictly formal conceptions”): M. Weber, “Bureaucracy and Law” in H. Gerth and C.W. Mills (eds.), From Max Weber: Essays in Sociology (London 1970).

⁸² See respectively London Gazette, 16185, 20 September 1808; London Gazette, 16293, 29 August 1809. The first of these announcements itself postdates the adoption of the Standing Order, but it seems reasonable to postulate that it took some time for the Order to come to the attention of petitioners.

⁸³ In this respect, it should be noted that copyright law at the time still contained a reversionary right that at least in theory allowed authors of successful works the opportunity to negotiate for an improved deal for the second half of the copyright term. It is possible that at least some members of the Lords had this in mind when the Standing Order was introduced. For discussion of the history of the reversionary right in copyright law, see Bently, L. and Ginsburg, J., “‘The sole right shall return to the Author’: Anglo-American Authors’ Reversion Rights from the Statute of Anne to Contemporary U.S. Copyright” (2010) 25 Berkeley Tech.L.J. 1475Google Scholar.

⁸⁶ The Judicial Committee was established in 1833: (1833) 3 & 4 Will. IV c. 41. This Act confined the legal work of the Privy Council to those who were appropriately qualified. In practice this meant that extensions were now under the control of the judiciary, with Lord Lydhurst, Lord Brougham, Bosanquet J., Lushington J., and Knight-Bruce V.C. being particularly active during the early period. Consequently, we find Knight-Bruce V.C. hearing a request for an extension in Wright's Patent (1843) 1 Web. Pat. Cas. 736 and an application for the grant of an injunction in Muntz v Foster (1843) 2 Web. Pat. Cas. 92 within days of one another. This point is worth emphasising because there has been a tendency to present the courts and the Privy Council as being in conflict in the patent field, but this characterisation of the relationship can only hold, at best, during a much earlier period. See further Bracha, Owning Ideas, pp. 62–63 (arguing that the narrative of continuous struggle between the courts and the Privy Council is in any event flawed) and P. Howell, The Judicial Committee of the Privy Council 1833–1876 (Cambridge 1979) (on the foundation and early operation of the Judicial Committee generally).
