Federal Circuit Issues Rule 36 Affirmance of PTAB After Acknowledging Lack of Technical Knowledge in Oral Arguments

On March 13th, the Court of Appeals for the Federal Circuit issued a decision in Cascades Projection v. Epson America, which upheld a ruling by the Patent Trial and Appeal Board (PTAB) to invalidate the asserted claims in a patent covering a system of projecting images using a liquid crystal display (LCD). During oral arguments, one judge of the Federal Circuit opined that it may not have enough testimony in order to decide the case correctly. To save themselves any discussion, the Federal Circuit panel of Circuit Judges Jimmie Reyna, Evan Wallach and Todd Hughes issued a Rule 36 affirmance of the PTAB’s decision, upholding the PTAB without discussing any reason as to why.

PTAB due process violations raised in brief to Federal Circuit

On September 22nd, a reply brief for appellant Cascades Projection LLC was filed to the U.S. Court of Appeals for the Federal Circuit in a case over the validity of patents covering projector technologies which were invented by Gene Dolgoff, the creator of the Star Trek Holodeck. The appeal against Japanese tech conglomerates Epson and Sony asks the Federal Circuit to decide whether the Patent Trial and Appeal Board (PTAB) erred in invalidating patent claims held by Cascades Projection and whether the PTAB acted in a manner which violated Cascade Projection’s right to due process under the U.S. Constitution.
