Trolling For Trolls: The Pitfalls Of The Emerging Market Competition Requirement For Permanent Injunctions In Patent Cases Post-Ebay, Benjamin H. Diessel Nov 2007

Trolling For Trolls: The Pitfalls Of The Emerging Market Competition Requirement For Permanent Injunctions In Patent Cases Post-Ebay, Benjamin H. Diessel

Michigan Law Review

In eBay v. MercExchange, a unanimous Supreme Court announced that a new four-factor test should be employed by district courts in determining whether to award an injunction or damages to an aggrieved party whose intellectual property has been infringed. In the context of permanent injunctions in patent cases, district courts have distorted the four-factor test resulting in a "market competition requirement." Under the new market competition requirement, success at obtaining an injunction is contingent upon a party demonstrating that it is a market competitor After consistent application in the first twenty-five district court cases post-eBay, the market competition requirement …


Exclusion Confusion? A Defense Of The Federal Circuit's Specific Exclusion Jurisprudence, Peter Curtis Magic Nov 2007

Exclusion Confusion? A Defense Of The Federal Circuit's Specific Exclusion Jurisprudence, Peter Curtis Magic

Michigan Law Review

Specific exclusion has become a controversial limitation on the doctrine of equivalents, which is itself an essential and controversial area of patent law. The doctrine of equivalents allows a patentee to successfully claim infringement against devices that are outside of the literal reach of the language used by the patentee in her patent to describe what she claims as her invention. The Supreme Court has prescribed some of the outer limits of the doctrine of equivalents and articulated the underlying policy concerns that inform its analysis-noting that courts should balance protection of the patentee's intellectual property with the public's reasonable …


Should Patent Infringement Require Proof Of Copying?, Mark A. Lemley May 2007

Should Patent Infringement Require Proof Of Copying?, Mark A. Lemley

Michigan Law Review

Patent infringement is a strict liability offense. Patent law gives patent owners not just the right to prevent others from copying their ideas, but the power to control the use of their idea--even by those who independently develop a technology with no knowledge of the patent or the patentee. This is a power that exists nowhere else in intellectual property (IP) or real property law, but it is a one that patentees have had, with rare exceptions, since the inception of the Republic. In an important paper in the Michigan Law Review, Samson Vermont seeks to change this, arguing …


"By Night She Fought For Fair Use": Restoring The Integrity Of Copyright Law, One Comic-Book Reader At A Time, Jessica Sawyer Wang Apr 2007

"By Night She Fought For Fair Use": Restoring The Integrity Of Copyright Law, One Comic-Book Reader At A Time, Jessica Sawyer Wang

Michigan Law Review

Students of copyright law quickly learn that the subject is counterintuitive. One of the first revelations of this is-somewhat alarmingly-the purpose of copyright itself. Contrary to popular belief, copyright is not just about protecting an artist's creation, but sharing it. Simultaneously protecting a work and sharing it helps to fulfill the Constitution's mandate that Congress "promote the Progress of Science ... by securing for limited Times to Authors ... the exclusive Right to their ... Writings." In other words, Congress is to promote learning and the advancement of our culture. The symbiosis of protecting and sharing is effected through the …


The Angel Is In The Big Picture: A Response To Lemley, Samson Vermont Jan 2007

The Angel Is In The Big Picture: A Response To Lemley, Samson Vermont

Michigan Law Review

An invention within close reach of multiple inventors differs from an invention within distant reach of a lone inventor. The differences between these two archetypes of invention -"reinventables" and "singletons"- remain unexploited under current U.S. law. Should we reform the law to exploit the differences? Mark Lemley and I agree that we should. To date, those economists who have closely examined the issue concur. What are the differences between reinventables and singletons? First, reinventables can be brought into existence with incentives of lower magnitude. This suggests that we can obtain reinventables at a lower price than we currently pay-i.e., with …
