The U.S. Supreme Court has decided to review the claim construction standard used by the Patent Trial and Appeal Board (PTAB) in AIA reviews In 2013, the PTAB invalidated a Cuozzo Speed Technologies patent through an inter partes review. Cuozzo appealed the decision to the Federal Circuit, which affirmed the PTAB’s use of the broadest reasonable interpretation standard for claim construction in an AIA review. Cuozzo is now asking the Supreme Court to review the use of the PTAB’s claim construction standard and to use the same standard used in district court patent cases. The PTAB construes claims broadly while district courts use a narrower standard. The PTAB’s standard, Cuozzo asserts, results in too many patent claims being invalidated. Cuozzo contends construing patent claims with their broadest reasonable interpretation allows more prior art to be used against the challenged claims increasing the chance the patent claim will be invalidated.
This case is important as it can potentially impact the decision making process of whether to challenge a patent in an AIA review or through district court litigation. It may also impact the amount of patents that are found to be invalid in AIA reviews.
