The Value Of U.S. Patents By Owner And Patent Characteristics, James Bessen

Faculty Scholarship

This paper uses renewal data to estimate the value of U.S. patents, controlling for patent and owner characteristics. Estimates of U.S. patent value are substantially larger than estimates for European patents, however, the ratio of U.S. patent value to R&D for firms is only about 3%. Patents issued to small patentees are much less valuable than those issued to large corporations, perhaps reflecting imperfect markets for technology. Litigated patents are more valuable, as are highly cited patents. However, patent citations explain little variance in value, suggesting limits to their use as a measure of patent quality.

Why Pharmaceutical Firms Support Patent Trolls: The Disparate Impact Of Ebay V. Mercexchange On Innovation, Jeremiah S. Helm

Michigan Telecommunications & Technology Law Review

Before the unanimous decision in eBay v. MercExchange, patent holders were almost always granted an injunction against an infringer. In fact, the Federal Circuit, in deciding eBay, noted that, upon a finding of infringement, an injunction would issue unless there were extraordinary circumstances. The Court, in a brief opinion, disagreed with the Federal Circuit and explained that the injunction issue in a patent case must be analyzed under the traditional four-factor test.[...] Is the four-factor test fairer or better than the Federal Circuit's near-automatic injunction rule? It is certainly more difficult to administer a factor test as compared to a …

Patentability Of Software Inventions, Umakant Mishra

Umakant Mishra

Software is very expensive to develop but very inexpensive to copy. Just by copying a software you create an exact duplicate of the original software and all with the same functionality. There is no difference between the original (which is bought) and the copy (pirated). The worse is when the source code is copied. The copier can even claim to have developed the software where the credit of the developer might go. The software developers use various methods to protect their source code such as copyright, trade secrets etc. but each having limitations. The developers are keen on finding legal …

A Comment On 'Do Patents Facilitate Financing In The Software Industry?', James Bessen

Faculty Scholarship

'Do Patents Facilitate Financing in the Software Industry?' by Ronald J. Mann contributes empirical evidence to our understanding of how software startups use patents. However, a close examination of the actual empirical findings in this paper points to rather different conclusions than those that Mann draws, namely: few software startups benefit from software patents and patents are not widely used by software firms to obtain venture financing. Indeed, among other things, the paper reports that 80% of venture-financed software startups had no acquired any patents within four years of receiving financing.

Pathological Patenting: The Pto As Cause Or Cure, Rochelle Dreyfuss

Michigan Law Review

The Patent Act was last revised in 1952. The hydrogen bomb was exploded that year, vividly demonstrating the power of the nucleus; in the ensuing postwar period, the Next Big Thing was clearly the molecule. Novel compounds were synthesized in the hopes of finding new medicines; solid-state devices exploited the special characteristics of germanium and other semiconductors; as investments in polymer chemistry soared, advice to the college graduate soon boiled down to "one word ... just one word[:] ... Plastics." Over the next half-century, things changed dramatically. "Better living through chemistry" has begun to sound dated (if not sinister). Genomics …

The Role Of Patents In Fostering Open Innovation, John Dubiansky

ExpressO

The patent system is at an inherent tension with contemporary practices of innovation. American patent doctrine reveres the lone inventor who, through the marshalling of extraordinary insight and experimental toil, conceives a novel invention. As a reward, the inventor is given the right to profit from his contribution through personal commercial exploitation. While this perspective may have reflected the practice of the mechanical arts at the time of the nation’s founding, it no longer reflects contemporary industrial research and development, where innovation is an increasingly networked process.

This disconnect is evidenced by the fact that contemporary patent doctrine has failed …

Three Tests Of Patentability, Umakant Mishra

Umakant Mishra

United States patent law prescribes three major criteria of patentability, viz, novelty, usefulness and non-obviousness. These "three tests of patentability" are fundamentals behind issue of any patent from USPTO. It is important to know these fundamentals for any person who intends to work on patents.

Intellectual Property: The Practical And Legal Fundamentals, Thomas G. Field Jr

Law Faculty Scholarship

Patents, copyrights, trademarks and related interests are known as intellectual property (IP). It has not been long since patents especially were regarded in U.S. courts, and the Supreme Court in particular, as tools of monopolists, and their owners often fared poorly. However, people have come increasingly to view privately funded innovation as critical to national economic well-being and to agree that such innovation cannot occur unless companies that succeed in the marketplace can recoup their research, development and marketing costs. That is a major function of IP, and, particularly within the past dozen years, IP has been seen, both here …

Accepting Exceptions?: A Comparative Approach To Experimental Use In U.S. And German Patent Law, Peter Ruess

Marquette Intellectual Property Law Review

Experimental use is a keystone of research and innovation for some and obstacle in using a patent for others. In a genuine international field such as patent law, monitoring recent developments is best done in a comparative way. Particularly, the decision Merck v. Integra of the US Supreme Court and the new EU law, give reason to explore this field in more detail.

Patent Buy-Outs For Global Disease Innovations For Low- And Middle-Income Countries, Kevin Outterson

Faculty Scholarship

Drug prices are uniquely susceptible to radical price reductions through generic competition. Patented pharmaceuticals may be priced at more than 30 times the marginal cost of production; the excess is the patent rent collected by the drug company while the patent and exclusive marketing periods remain. Patent rents are significant. AIDS drugs which sell for US$10,000 per person per year in the US are sold generically for less than US$200. If patented drugs could be sold at the marginal cost of production, cost effective treatments would become even more attractive, and other interventions would become affordable.

This Article proposes marginal …

Estimates Of Patent Rents From Firm Market Value, James Bessen

Faculty Scholarship

The value of patent rents is an important quantity for policy analysis. However, estimates in the literature based on patent renewals might be understated. Market value regressions could provide validation, but they have not had clear theoretical foundations for estimating patent rents. I develop a simple model to make upper bound estimates of patent rents using regressions on Tobin's Q. I test this on a sample of US firms and find it robust to a variety of considerations. My estimates correspond well with estimates based on patentee behavior outside the pharmaceutical industry, but renewal estimates might be understated for pharmaceuticals.

Social Software, Groups, And Governance, Michael J. Madison

Articles

Formal groups play an important role in the law. Informal groups largely lie outside it. Should the law be more attentive to informal groups? The paper argues that this and related questions are appearing more frequently as a number of computer technologies, which I collect under the heading social software, increase the salience of groups. In turn, that salience raises important questions about both the significance and the benefits of informal groups. The paper suggests that there may be important social benefits associated with informal groups, and that the law should move towards a framework for encouraging and recognizing them. …
