Intel, AMD Lose IPR Bid Against Advanced Cluster Patent Also Survived Nvidia Challenge

Intel and AMD have failed to invalidate a cluster-computing patent asserted by Advanced Cluster Systems, in a setback mirroring an earlier unsuccessful challenge by NVIDIA.

In decisions issued in August and September 2025, the Patent Trial and Appeal Board declined to institute inter partes review of U.S. Patent No. 10,333,768, titled "Cluster Computing," which had been challenged separately by Intel and AMD.

The PTAB, however, did institute review of four related Advanced Cluster Systems patents challenged by Intel and AMD in November 2025. Those patents include U.S. Patent Nos. 11,563,621; 11,570,034; 11,811,582; and 12,021,679, all sharing the same "Cluster Computing" title.

Advanced Cluster Systems sued Intel and AMD for infringement of the same five patents in September 2024 in the U.S. District Court for the Western District of Texas.

Notably, the '768 patent has also survived a prior IPR challenge by NVIDIA. The chipmaker petitioned for review in October 2020, but the PTAB denied institution in May 2021, a history that may underscore the patent’s perceived strength.

The asserted patents cover distributed computing and cluster control technology, describing software-based orchestration that enables multiple computing nodes to interpret and distribute instructions via a user interface and kernel, communicate with one another, and operate collectively as a unified computer cluster.
