PTAB Authorizes Patent Owner to Seek Third­-Party Subpoena in District Court

The district of Delaware recently denied a defendant’s partial motion to dismiss pre-suit willful infringement from the litigation, finding instead that the allegations taken as a whole were sufficient to support pre-suit willfulness at the pleading stage. Specifically, the court found that the allegations as to the defendant’s involvement in a related foreign opposition proceeding and participation in the relevant industry were accompanied by detailed factual support that sufficiently pleaded willful infringement for the pre-suit period.

The Ninth Circuit recently reversed a district court’s decision to strike a plaintiff’s trade secret claims under the Defend Trade Secrets Act (DTSA) at the discovery stage. In doing so, the Ninth Circuit made clear that under the DTSA, whether a party defined their trade secret with sufficient particularity is a question of fact that generally does not lend itself to resolution in the absence of at least some discovery. This ruling contrasts with the California Uniform Trade Secrets Act (CUTSA), which requires a party to define their trade secrets with reasonable particularity before commencing discovery.

The Federal Circuit recently vacated a summary judgment ruling of invalidity, holding that the district court erred in applying preclusive effect to the Patent Trial and Appeal Board’s unpatentability findings regarding other claims in the same patent. In doing so, the Federal Circuit reiterated that issue preclusion does not apply where the prior factual determinations were made under a lower standard of proof.

The Federal Circuit recently clarified the requirement for work disclosed in a reference to qualify as “by another” under pre-AIA Sections 102(a) and (e), holding that there must be complete inventive identity between the information disclosed in the asserted reference and the inventors named on the relevant patent.
