Post-Amgen Claiming Techniques in Focus

Last year’s landmark decision in Amgen V. Sanofi emphasized that “the more a party claims, the broader the monopoly it demands, the more it must enable.” That is, particularly when claiming a broad genus of antibodies, the specification cannot be a research assignment to engage in trial and error as to the recited claim scope.

Since that time and perhaps dealing with inadequate specifications filed prior to Amgen, prosecutors have considered whether fallback claiming techniques such as Jepson format claiming or mean-plus-function formatted claims can at least secure some protection in the case where broader claims fail.

The USPTO is now committed to providing clarity on these topics in In re Xencor.Continue Reading USPTO Appeals Panel to Clarify Antibody Claiming in MPF & Jepson Format

Empirical Studies Refute Oft Repeated Fallacies

The PTAB released two studies on historical petition filing practices this month. One directed to the frequency of so-called serial/parallel petition filings, and the other pertaining to Orange Book/Biologics patents. As with the agency’s earlier studies on these same topics (2021), the refreshed data again demonstrates that Orange Book patents are very rarely subject to AIA trial proceedings, and that abusive, serial petition filings have been effectively outlawed for years now.

Of course anyone that actually practices before the PTAB is well-aware of these realities. So, these empirical studies are primarily directed to the oft repeated criticisms of moneyed lobbyists and disingenuous critics at a time when both Congress and the agency grapple with wildly conflicting narratives.Continue Reading PTAB Data Belies Outdated Criticisms
