Nothing New in the World of Patents: "Patent Licensing and Secondary Markets in the Nineteenth Century"

In a recent blog post "Nothing New Under the Sun: “Patent Trolls” Have Been Around Forever," I discussed Professor Zorina Khan's review of Nineteenth century patent assertion entities.  In a recent essay, Professor Adam Mossoff of George Mason University Law School provides another supportive account of patent licensing and secondary markets in the Nineteenth century.  Specifically, Professor Mossoff, in a short and readable paper, "calls out" those commentators who assert that the "patent licensing business model" is a new phenomena. Professor Mossoff summarizes and reviews Professor Khan's research as well as the research of other historians that demonstrates there really is nothing new (at least not much) in the world of patents. 

Professor Mossoff provides the example of three inventors who licensed their patents.  He discusses Charles Goodyear (process for vulcanized rubber), Elias Howe, Jr. (lockstitch in sewing machines), and Thomas Alva Edison.  About Goodyear, Mossoff notes, "Some of Goodyear's assignees and exclusive licensees, who were patent licensing companies themselves, filed hundreds of lawsuits in the nineteenth century; they sued firms, individuals, and even many end-users such as dentists, for patent infringement."  He further states that, "Contrary to many claims today, end-user lawsuits even by patent licensing companies are nothing new in America's innovation economy."  

Notably, Mossoff states that Howe used "third-party litigation financing."  Howe also joined "the first patent pool in American history."  "[Howe] made almost the entirety of his fortune on the basis of the royalty stream from his license to this patent pool, which further licensed his rights to other companies."  Mossoff makes an interesting point about Edison.  Interestingly, he notes that Edison was famously a terrible businessman, but a great inventor.  The point here seems to be that specialization matters--licensing for commercialization to those who know how to do it is critical to getting patented inventions to the public. Not all inventors will be good businessmen--experts in manufacturing or finance. Edison's "employ[ment of] the patent licensing business easily meets today's definition of an 'NPE.'"  

Professor Mossoff also provides interesting examples of the secondary market, which include the classified advertisements in the magazine Scientific American. The classified advertisements included numerous "ads for the sale of patents and patent rights."  Moreover, he discusses the research of economists Naomi R. Lamoreaux, Kenneth Sokoloff, and Dhanoos Sutthiphisal: "Their research revealed the fundamental and significant role performed by a group of market intermediaries known at the time as 'patent agents.'"  Professor Mossoff asserts that these "patent agents" are "predecessors of today's patent aggregators." 

Finally, Professor Mossoff states that a historian notes "after detailing the problems for nineteenth-century inventors who usually lacked manufacturing and commercial finance skills, that 'given the risks associated with manufacturing, many nineteenth-century inventors preferred to either sell or license their patents.'"  He concludes that, "In sum, it is simply false to assert that these commercial mechanisms for bringing patented innovation to market are a new phenomenon today." What should be the role of this type of research given the state of the debate on NPEs/PAEs today?  Does it change the analysis concerning the merits of NPEs/PAEs?
