Singular Computing LLC has filed a second case against Alphabet (Google) (1:19-cv-12551), asserting the two most recent patents to issue in the same family from which the three patents already in suit are drawn. The inventor-controlled NPE again targets the use of certain Google Tensor Processing Units (application-specific integrated circuits (ASICs) used for AI acceleration). The accused TPUs—specifically, the TPU v2, v3, and v4—are allegedly used to “deliver services such as Translate, Photos, Search, Assistant, Cloud and Gmail”. Singular Computing’s first suit against Google, filed in December 2020, also in the District of Massachusetts, is under a partial stay until May 2022.
