Federal Circuit patent decisions

The Federal Circuit vacated a $12.7 million copyright damages award against the government for unauthorized copying of healthcare interoperability software, holding that courts misapplied the ‘book of wisdom’ by considering unforeseeable events and that punitive willful-infringement damages are unavailable under 28 U.S.C. § 1498(b).

The Federal Circuit vacated a PTAB decision upholding Parus Holdings’ voice-browsing patent against Google’s IPR challenge, holding that the Board improperly analyzed prior art in isolation rather than in combination, secretly construed a claim term without notice to Google, and failed to explain its inconsistency with earlier IPR rulings on related Parus patents.

The Federal Circuit affirmed that ClickFunnels’ sales-funnel website creation patents are invalid under § 101, holding that the abstract idea of “filtering information based on user preferences” cannot be rescued by conventional template-selection and sequential-webpage features, while also clarifying the burden-shifting framework for representative-claim analysis.

The Federal Circuit affirmed Intel’s summary judgment win, finding PACT XPP forfeited its capability-based infringement theory on the ‘301 patent and that prosecution statements during ex parte reexamination narrowed the ‘593 patent’s ‘physically dedicated connection’ claim to exclude Intel’s shared-bus architecture.

The Federal Circuit reversed and remanded a district court’s IPR estoppel ruling for the second time, holding that a classification search returning 26,333 results cannot show a prior art reference was “reasonably discoverable,” and that Cardinal IP’s search evidence for a second invalidity ground was tainted by hindsight bias throughout.
In a precedential decision, the Federal Circuit reversed district court estoppel orders that had blocked Valve from using two prior-art grounds at trial, holding that classification searches returning 26,333 results do not establish discovery and that hindsight-infected forward citation searches cannot prove what a 2016 petitioner reasonably could have raised.

In a nonprecedential ruling, the Federal Circuit affirmed that copyright infringement claims against the U.S. government must proceed exclusively under 28 U.S.C. §1498(b) and cannot be recast as Tucker Act ‘takings’ claims — a ruling arising from a pro se plaintiff’s allegation that the government used his AI dissertation without compensation.

The Federal Circuit reversed a $452 million jury verdict, holding that Insulet’s trade secret misappropriation claim under the Defend Trade Secrets Act was time-barred because Insulet knew or should have known of the alleged misappropriation more than three years before filing suit.

In a companion case to ALM Holding v. Zydex, the Federal Circuit held that Medtronic Ireland retained Article III standing to assert patent infringement counterclaims despite licensing exclusive rights to an affiliate, because it kept the right to sue, sublicensing veto, and royalty interests.
