Do Patent Challenges Increase Competition?, Stephen Yelderman Oct 2016

Do Patent Challenges Increase Competition?, Stephen Yelderman

Journal Articles

This Article is the first to seriously scrutinize the claim that patent challenges lead to increased competition. It identifies a number of conditions that must hold for a patent challenge to provide this particular benefit, and evaluates the reasonableness of assuming that the pro-competitive benefits of patent challenges are generally available. As it turns out, there are a number of ways these conditions can and regularly do fail. This Article synthesizes legal doctrine, recent empirical scholarship, and several novel case studies to identify categories of challenges in which the potential benefits for competition are smaller than previously thought or, in ...


Coordination-Focused Patent Policy, Stephen Yelderman Oct 2016

Coordination-Focused Patent Policy, Stephen Yelderman

Journal Articles

This Article explores the practical consequences of an important shift that has recently taken place in patent theory. Although it was long agreed that the purpose of granting patents is to reward invention, today many scholars instead attempt to justify the patent system based on its role in facilitating information exchange and enabling technical coordination among firms. This change in justification is controversial, and its viability remains a fiercely contested question. But despite intense attention at the level of theory, little has been said about the consequences of this debate for patent policy itself. This Article addresses that void, developing ...

Brief Of Amici Curiae Intellectual Property Law Professors, Mark Mckenna, Rebecca Tushnet

Court Briefs

The District Court correctly determined that the challenged speech of Dr. Steven Novella was not commercial speech for purposes of applying the Lanham Act. Appellant’s argument to the contrary conflates “seeking profit” with “commercial speech.”


Brief Amici Curiae Of 37 Intellectual Property Professors In Support Of Petition For Certiorari, Mark A. Lemley, Mark Mckenna Jan 2016

Brief Amici Curiae Of 37 Intellectual Property Professors In Support Of Petition For Certiorari, Mark A. Lemley, Mark Mckenna

Court Briefs

This case presents two issues that justify this Court’s review.

First, the Federal Circuit upheld a finding of design patent infringement based on the very same Apple designs that it found functional under trade dress law. Such a counterintuitive outcome is possible because the Federal Circuit has constructed a highly constrained definition of functionality in design patent law, which is at odds with this Court’s precedent in both utility patent and trade dress cases. Coupled with its recent re-interpretation of the design patent infringement standard, the Federal Circuit’s approach to functionality makes it quite likely that defendants ...


Brief Of Amici Curiae On Behalf Of Intellectual Property Professors In Support Of Petitioner, Mark Mckenna, Mark A. Lemley, Christopher Jon Sprigman, Rebecca Tushnett Jan 2016

Brief Of Amici Curiae On Behalf Of Intellectual Property Professors In Support Of Petitioner, Mark Mckenna, Mark A. Lemley, Christopher Jon Sprigman, Rebecca Tushnett

Court Briefs

In its 1976 revision of the Copyright Act, Congress decided to separate applied art from industrial design, admitting the former to copyright and excluding the latter. It drew this distinction precisely because it intended to differentiate copyright from design and utility patent. Congress recognized as applied art only those aesthetic features of a useful article that could be “separated” from that useful article rather than being integrated into the article.

The correct test of separability therefore considers conceptual separability to be nothing more than a coda to physical separability, and asks only whether the claimed design could be removed from ...


Scope, Mark Mckenna, Mark A. Lemley Jan 2016

Scope, Mark Mckenna, Mark A. Lemley

Journal Articles

Virtually every significant legal doctrine in IP is either about whether the plaintiff has a valid IP right that the law will recognize (validity); whether the defendant's conduct violates that right (infringement); or whether the defendant is somehow privileged to violate that right (defenses). IP regimes tend to separate doctrines in these three legal categories relatively strictly. They apply different burdens of proof and persuasion to infringement and validity. In many cases they ask different actors to decide one doctrine but not the other. And even where none of that is true, the nature of IP law is to ...
