U.S. Patent and Trademark Office Director John Squires has designated as "informative" a Director Review decision that expands on how the agency treats petitioners who adopt inconsistent claim constructions during inter partes review. The decision relies on the recently designated precedential ruling in Revvo Technologies, Inc. v., signaling that the USPTO intends to apply that framework more broadly.
Observers see the designation as part of Squires' continuing pro-patent owner approach in Director Review. By marking the decision as informative, the USPTO provides guidance to future panels and litigants on the standards for evaluating shifting claim interpretations, without making the decision itself precedential.
The source notes that this is the latest in a series of actions by Squires that tilt toward patent owners. However, the article does not compare this decision to any other source, so no differing views are available. The practical effect is that petitioners may face greater scrutiny when their claim constructions change over the course of a proceeding.
