According to BusinessWire,Tachyum, a general-purpose processor design company, announced that it has taken legal action to maintain the exclusive rights of its registered "TPU" trademark and requires Google to stop using the abbreviation "TPU" in the field of artificial intelligence (AI).
Tachyum's "TPU" stands for "Tachyum Processing Unit", which is its licensable hardware IP core for IoT and edge AI inference.The company first submitted the "TPU" trademark application in 2015 and has officially held the trademark rights since October 2020.
The "TPU" used by Google is the abbreviation of "Tensor Processing Unit". Google's first-generation TPU product was put into use in 2015 and was officially announced at the 2016 Google I/O Developer Conference.
It is worth noting that Google only submitted a trademark application for “Google TPU” in November this year (2025).
Tachyum believes that the two companies' use of the same "TPU" logo in the AI market constitutes a trademark conflict.
Radoslav Danilak, the company’s founder and CEO, said: “Google’s unauthorized use of ‘TPU’ constitutes infringement, causes market confusion, and harms our business prospects in the AI market.”
