The Federal Circuit affirmed the ITC’s finding that Tineco’s redesigned wet-dry vacuum cleaners do not infringe BISSELL’s patents, while also establishing that ITC experts may rely on source code produced in discovery but never formally admitted as a hearing exhibit under FRE 703.

Infineon v. Innoscience — ITC Import Ban on GaN Chips Takes Effect, But Only for Discontinued Products

The U.S. ITC’s limited exclusion order against Innoscience’s GaN power devices became effective July 7, 2026 after the Presidential Review Period expired, but the ruling’s practical impact is narrow: only two claims of Infineon’s ‘481 patent were found infringed, and only by Innoscience’s already-discontinued legacy products.

Maquet v. Abiomed — Court Issues Three Pre-Trial Rulings on Blood Pump Patent, Preserves Written Description Challenge but Strikes Indefiniteness and Means-Plus-Function Arguments

In three pre-trial rulings, the District of Massachusetts denied summary judgment on Abiomed’s written description defense, eliminated its indefiniteness arguments, declined to kill the reverse doctrine of equivalents, and found waiver on a last-minute means-plus-function claim construction bid — setting the stage for trial on Maquet’s intravascular blood pump patent.

Gilead Sciences v. Academy of Military Medical Sciences — UPC Revokes Chinese Military Institute’s Remdesivir COVID-19 Patent for Lack of Inventive Step

The UPC Central Division in Milan revoked the Academy of Military Medical Sciences’ European patent on the use of remdesivir to treat COVID-19, finding the claimed invention lacked inventive step because prior art published just ten days before the priority date already identified remdesivir as likely effective against the newly emerged Wuhan coronavirus.

Headwater Research v. Verizon — Judge Gilstrap Wipes Out $175M Patent Verdict With Implied Waiver

Judge Gilstrap finds that Headwater Research LLC — which knew of Verizon’s patent infringement in 2017 but waited six years to file suit in order to maximize its damages window — engaged in conduct so inconsistent with an intent to enforce its rights that equity bars enforcement entirely, wiping out a $175 million jury verdict. The court holds that implied waiver survives the Supreme Court’s SCA Hygiene decision, which abolished laches, because waiver goes to liability rather than damages.
