Tachyum Initiates Action Against Google Over TPU Trademark Infringement in AI Chip Market

Tachyum announced it is taking steps to defend its registered TPU trademark against Google’s use of the term TPU for its Tensor Processing Unit.

Tachyum applied for the TPU trademark in September 2015 and was granted registration in October 2020 for its AI Tachyum Processing Unit. Google filed for trademark protection of Google TPU on November 21, 2025.

Tachyum has requested Google to cease using TPU as a descriptor for its Tensor Processing Unit and stated it will petition the U.S. Trademark Office to reject Google’s application.

Tachyum licenses its TPU AI intellectual property as a core for IoT and edge devices and claims sole ownership of the TPU trademark within the AI processor category.

Dr. Radoslav Danilak, founder and CEO of Tachyum, stated: “Google’s unlicensed use of TPU represents an infringement that creates confusion and harms our business prospects within the AI marketplace. We are re-asserting our claim to the trademark rights of TPU as solely our corporate asset, and request that Google and others refrain from infringement to describe their similarly competitive products and services in the AI space.”
