AMD and Pensando’s IPR petition against the ’596 patent is challenged by Concurrent Ventures and XtreamEdge, who argue the petition fails to identify claim construction and does not show prior art meets the claimed hardware queue limitations, seeking a discretionary denial of institution.
Tesla, Inc. v.Intellectual Ventures II LLC
Tesla has filed an IPR petition seeking to invalidate claims 1‑2, 5, 7‑8, and 11 of Intellectual Ventures’ ’395 patent on the ground of obviousness over Moir and Martínez. The petition also argues that discretionary denial is unwarranted.
NVIDIA Corporation v.Neural AI, LLC
NVIDIA has filed a rehearing request challenging the PTAB Director’s denial of institution for its IPR against Neural AI’s GPU‑AI patent. The petitioner argues the Board ignored trial‑date timing data and the patent’s recent issuance, which should weigh against discretionary denial.

NVIDIA has filed a rehearing request challenging the PTAB Director’s denial to institute an IPR on its GPU‑related patent. The company contends the Board ignored time‑to‑trial statistics and the lack of commercialization, which should favor institution.
NVIDIA Corporation v.Neural AI, LLC
NVIDIA has filed a petition for inter partes review of Neural AI’s U.S. Patent 8,648,867, seeking to invalidate claims 1‑19 on obviousness grounds. The petition relies on NVIDIA’s own earlier patents (Nickolls and Kirk) together with the GPU Gems book to show that the claimed accelerator controller and pointer‑swapping were known.
