US ITC: Samsung does not infringe Nvidia graphics chip patents, another Nvidia patent is invalid
Context & Ripple Effects
Nvidia opened a two-front patent war with Samsung when the ITC agreed in December 2014 to investigate Samsung's claims that Nvidia GPUs infringed its patents — and Nvidia answered with its own infringement allegations against Samsung. Nvidia briefly had the momentum after winning an April 2015 Markman claim-construction ruling, but this decision guts that counteroffensive: the commission finds Samsung clean on the graphics chip patents and kills another Nvidia patent outright.
The stakes were never just royalties — an adverse ITC finding can mean an exclusion order blocking imports, which is why the parallel Samsung-side case mattered so much. A judge had already ruled in December 2015 that Nvidia infringed three Samsung patents, leaving Nvidia exposed on defense while its own offense now fails.
First-order effects
- Samsung exits this round without liability on Nvidia's graphics chip patents, removing any threat of an import ban built on Nvidia's counterclaims.
- Nvidia loses licensing leverage it was building toward: one patent is held invalid and the rest non-infringed, weakening its position in both the ITC case and the parallel district-court fight.
Second-order effects
- With Nvidia's countersuit dead, all pressure runs one way — Samsung's infringement findings stand unbalanced, pushing the dispute toward the negotiated end it eventually took when Nvidia settled hours before the ITC ruling rather than risk an import ban.
- Qualcomm, named alongside Samsung in Nvidia's original complaint, benefits from the same clearing: the ITC's reasoning undercuts the theory behind Nvidia's claims against the broader Android silicon supply chain.
Third-order effects
- If the pattern holds, smartphone-chip patent wars increasingly resolve through portfolio swaps and last-minute settlements rather than exclusion orders, because each side's countersuits keep canceling out at the ITC.
- For chip designers, the episode reinforces the ITC as a high-stakes venue where an entire patent family can be invalidated in one proceeding — raising the bar for filing defensive countersuits.
The trend: Mobile-GPU patent conflicts are converging on negotiated cross-licensing peace, with the ITC's dual-track rulings forcing both chipmakers to settle rather than face import bans.
