Historical example of the Daguerre buyout process actually brings up substantial concerns about potential for innovation

Patent buyouts are often proposed because they would allow ideas to circulate freely and because such access enables cumulative inventions to flourish without the transactions costs and deadweight loss that a monopolistic right of exclusion might impose. The Daguerre-Niépce method did indeed spread quickly, comprising an undoubted benefit of the French policy, but this approach to photographic reproduction was also short-lived as the dominant process in the marketplace. Instead, the English inventor William Fox Talbot independently patented a technique in 1841 through which photographic prints could be developed from negatives, and it was this approach that ultimately prevailed throughout the nineteenth and twentieth centuries, in the predigital era. The buyout of the Daguerre process also created its own problem of cumulative invention, by putting in the public domain all of the efforts of prior inventors whose work was incorporated in the Daguerreotype, without their permission and without offering them any compensation. Questions remain about whether the monetary award accurately gauged the true value of the invention, given the availability of substitutes that were not taken into account in the public accounting; the deadweight loss of taxation and redistributive effects of using public funds to benefit one group in society (photographers); and, ultimately, the incentives that such a policy creates for inefficient rent seeking and patronage on the part of inventors and their influential connections.
