Fixing Patent Boundaries, Tun-Jen Chiang
Fixing Patent Boundaries, Tun-Jen Chiang
Michigan Law Review
The claims of a patent are its boundaries, defining the scope of exclusion. This boundary function of claims is undermined by the fact that claims can be changed throughout the life of the patent, thereby moving the patent boundary. A boundary that can be moved at-will is one that the public cannot rely upon. This Article explores the problems of malleable patent boundaries. If a claim can be amended to permit a patentee to capture something he did not foresee when filing the patent application, the amendment confers an unexpected windfall that did not contribute to incentives to invent before …

Pioneers Versus Improvers: Enabling Optimal Patent Claim Scope, Timothy Chen Saulsbury
Michigan Telecommunications & Technology Law Review
Arising most commonly as a defense to an infringement claim, enablement requires a patent to describe the claimed invention in sufficient detail to permit a person having ordinary skill in the relevant field to replicate and use the invention without needing to engage in "undue experimentation."

This penalty deters patent applicants from claiming more than they invented and allows others to …

Copyright law performs a number of important functions. It facilitates public access to knowledge and a wide range of uses of creative works of authorship, and, in so doing, it helps educate our populace, enrich our culture, and promote free speech, free expression, and democratic values. It provides opportunities for rights holders to recoup investments in creating and disseminating their works and to enjoy the fruits of whatever success arises from the public's uses of their works. In the process, copyright also plays a role in regulating new technologies and services through which creative works may be accessed. A well-functioning …
