Federal Circuit Reverses PTAB Claim Construction, Reviving Cooling Patent

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Thursday, March 7, vacated a decision of the Patent Trial and Appeal Board (PTAB) that had held unpatentable certain claims to CoolIT Systems, Inc.’s patent. U.S. Patent 9,057,567 is titled “Fluid Heat Exchange Systems” and is directed to a system for fluid heat transfer to cool electronic devices. On appeal to the CAFC, CoolIT argued that the PTAB erred in construing one of the claim terms, “matingly engaged” and that even under the PTAB’s construction, the asserted prior art did not meet the matingly engaged limitation.

CAFC Puts Patent Community on Notice of Sanctions for Incorporation by Reference Violations

On February 16, the U.S. Court of Appeals for the Federal Circuit issued a pair of precedential rulings in Promptu Systems Corp. v. Comcast Cable Communications, LLC, vacating a final judgment of infringement after reversing part of the district court’s claim construction rulings. The entire U.S. patent community, however, should take notice of the Federal Circuit’s sua sponte order informing future litigants that evading briefing limits by incorporating much larger documents by reference will likely result in sanctions.

CAFC Says Dialogue with Intended Audience Establishes Publication for Prior Art Purposes

On February 8, the U.S. Court of Appeals for the Federal Circuit issued a precedential decision in Weber, Inc. v. Provisur Technologies, Inc. that vacated rulings by the Patent Trial and Appeal Board (PTAB) nixing validity challenges by American grill maker Weber against Provisur’s commercial food slicer patent claims. The Federal Circuit reversed the PTAB on claim construction and also found that the Board misapplied CAFC precedent on the level of public dissemination required before printed publications can qualify as prior art.

CAFC Clarifies Determination of ‘Implicit’ Claim Constructions

The U.S. Court of Appeals for the Federal Circuit (CAFC) today issued a precedential decision vacating and remanding a Patent Trial and Appeal Board (PTAB) decision that a patent for a climate control system was not proven unpatentable by Google LLC and Ecobee, Inc. In so doing, the court clarified how to determine when a court or the PTAB has implicitly construed a claim.

Failure to Construe Claims ‘As a Whole’: A Hole in Our Strategy?

For decades, patent litigators have followed what can best be described as a forced march seeking to construe patent terms and thereafter litigate infringement and/or validity issues based on those constructions. We all know the drill: exchange contentions; flag contested claim terms; brief their constructions; apply the facts to the court’s constructions; and grind out infringement and validity evidence like so much sausage. Rarely do litigants ask courts to take a step back and construe an asserted claim “as a whole,” and rarely do courts do so if they have not been asked. But sometimes the lack of a holistic claim analysis can lead to a shock to the system at trial, at which time one narrowly construed term can steamroller another broader construed term. The result can be the loss of an infringement claim or an invalidity defense. Such losses may or may not be avoidable, but facing the music earlier can save everyone a great deal of time and resources.
