The Central Claiming Renaissance, Andres Sawicki

Articles

The Supreme Court has recently reinvigorated the law of patentable subject matter. But beneath the headlines proclaiming the return of limits to patent eligibility, a more profound shift has taken place: central claiming is reborn.

The Court's eligibility cases are significant outliers compared to today's run-of-the-mill patent law because claim language plays little role in their analyses. In our modern peripheral claiming system, the claim language is the near exclusive guide to the patent's boundaries. But in its earliest days, our patent system pursued a central claiming approach, in which the inventor's actual work determined the patent's scope. The Court's …

Patent Uncertainty: Toward A Framework With Applications, Keith N. Hylton

Faculty Scholarship

There are three essential sources of uncertainty in the patent system: perceived uncertainty due to selective sampling (“statistical artefact uncertainty”), inherent uncertainty, and strategic uncertainty. It is only the strategic uncertainty source that should be of concern to reformers. With respect to this source, uncertainty in the patent system is largely a function of two variables: the degree of inherent abstraction associated with the patent, and the degree to which the patent provides notice of its scope. The maximal degree of uncertainty is observed in the category of abstract patents with poor notice, a category dominated today by software patents. …

The Debilitating Effect Of Exclusive Rights: Patents And Productive Inefficiency, William Hubbard

All Faculty Scholarship

Are we underestimating the costs of patent protection? Scholars have long recognized that patent law is a double-edged sword. While patents promote innovation, they also limit the number of people who can benefit from new inventions. In the past, policy makers striving to balance the costs and benefits of patents have analyzed patent law through the lens of traditional, neoclassical economics. This Article argues that this approach is fundamentally flawed because traditional economics rely on an inaccurate oversimplification: that individuals and firms always maximize profits. In actuality, so-called "productive inefficiencies" often prevent profit maximization. For example, cognitive biases, bounded rationality, …

Invention, Refinement And Patent Claim Scope: A New Perspective On The Doctrine Of Equivalents, Michael J. Meurer, Craig Allen Nard

Faculty Scholarship

The doctrine of equivalents (DOE) allows courts to expand the scope of patent rights granted by the Patent Office. The doctrine has been justified on fairness grounds, but it lacks a convincing economic justification. The standard economic justification holds that certain frictions block patent applicants from literally claiming appropriately broad rights, and thus, the DOE is available at trial to expand patent scope and overcome these frictions. The friction theory suffers from three main weaknesses. First, the theory is implausible on empirical grounds. Frictions such as limits of language, mistake, and unforeseeability are missing from the leading cases. Second, there …
