ANPRM an Unnecessary Slog to a Small Rule Package

It has been almost a year since the Patent Trial & Appeal Board (PTAB) released its Advanced Notice of Proposed Rulemaking (ANPRM) on AIA trial practices. As a reminder, the ANPRM was a sprawling collection of rule proposals and requests for public feedback. I previously pointed out that the proposal was unnecessarily ambitious and was destined to be bogged down for proposing to exceed the agency’s regulatory jurisdiction.

Well, the wait is almost over. Continue Reading Where are the New PTAB Rules?

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

Common AIA Issues Discussed

This coming Thursday January 18th (noon to 1 p.m. (EST)) the PTAB will host its first Boardside Chat of the year. The program will discuss issues that typically arise during an America Invents Act (AIA) proceeding before the Board (PTAB). Topics will include:
• Preparing a patent owner preliminary response

Claim-Based Analysis Required for Pre-AIA Patents Only

One of the more confusing developments in patent law was pronounced in Dynamic Drinkware v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). In Dynamic the Court held that a provisional application’s effectiveness as prior art under 102(e) depends on its written description support for the claims of the issued patent. In other words, if the patent claims ABC, and C is not supported in the provisional, the provisional loses 102(e) prior art status for all of its disclosure. So, if looking to use the provisional date for AB alone, which is supported, the claim-based analysis would still prevent such reliance.

The applicability of the strange claim-driven analysis of Dynamic was recently considered relative to AIA patents. Today’s precedential PTAB decision makes clear that the AIA statutory framework dispensed with this faulty claim-centric scheme.Continue Reading Dynamic Drinkware Analysis Unnecessary for AIA Patents

Leveraging Written Description Vulnerabilities in IPR

Bio/pharma patents are rarely targeted in IPR proceedings because their technical vulnerabilities often relate to written description and/or enablement. IPR, of course, is restricted in scope to only grounds of unpatentability that are based on patents and printed publications. And claims in the unpredictable arts, even when challenged in IPR, can be relatively tougher to invalidate as compared to patents in the predictable arts.

That is not to say that 112 issues cannot be litigated in an IPR—only that 112 cannot be a stand-alone trial ground. For example, where a subject patent claims priority to one or more prior filings, the 112 support of those filings is properly litigated in IPR if the claims of the subject patent are argued as lacking support in the earlier filings. The distinction is that 112 is not being assessed as a stand-alone challenge, but rather, as part of the priority assessment to determine the applicability of intervening prior art under 102/103.

The above IPR strategy is not new. However, it might be significantly more valuable to Bio/Pharma patent challengers as a mechanism to force an Amgen analysis on older patent portfolios via IPR.Continue Reading Amgen Analysis: An Emerging PTAB Threat For Bio/Pharma

CAFC: Success/Motivation Record Intertwined in Predictable Arts

As borne out by historical PTAB statistics, and not unexpectedly so, patents in the unpredictable arts are more likely to withstand PTAB scrutiny as compared to patents in the predictable arts. For example, formulating a pharmaceutical has a lot more variables and unknowns than adding a drop-down menu to a particular computer interface. The latter requiring only a change in computer code. For this reason a successful obviousness challenge in the unpredictable arts typically requires far more evidence/effort on such showings as “expectations of success” in combing prior art references.

That is not to say that Patent Owners in the predictable arts should forego potential arguments on expectation of success. Rather, such Patent Owners need to be mindful that an expectation of success argument may have a limited shelf-life.Continue Reading Early Opportunity for PTAB Patent Owners – Expectation of Success
