OpenAI US12608439B2 Patent: Transposed Matrix-Vector Multiplication
Summary
USPTO granted Patent US12608439B2 to OpenAI OpCo, LLC on April 21, 2026. The patent covers a system and method for performing vector-matrix multiplication (VMM) where the matrix transpose for stationary weights can be computed without moving data in memory. The patent includes 20 claims and has been assigned CPC classifications in AI/neural network hardware acceleration.
What changed
USPTO granted OpenAI OpCo, LLC Patent US12608439B2 titled "System and method of transposed matrix-vector multiplication." The patent describes hardware compute logic coupled with memory cells storing matrix weights, configured to perform vector-matrix multiplication for both the matrix and its transpose with weights remaining stationary in memory cells.
Technology companies developing AI accelerators, neural network hardware, or matrix computation systems should review this patent for potential licensing considerations. The patent's claims covering stationary-weight VMM operations may be relevant to hardware designers working on in-memory computing architectures for deep learning applications.

Abstract
A system including a memory and hardware compute logic is described. The memory includes memory cells storing weights corresponding to a matrix. Hardware compute logic is coupled with the memory cells. The hardware compute logic is configured to perform a vector-matrix multiplication (VMM) for the matrix and for a matrix transpose for the weights being stationary for the memory cells.
