Patent owner ParTec AG, along with its exclusive licensee and eventual “licensing agent” BF exaQC AG (BFX), has sued Microsoft (2:24-cv-00433) over the provision of the Microsoft Azure AI system and related infrastructure. Three “cluster computing” patents are asserted in the Eastern District of Texas complaint, which outlines a series of agreements between the parties that transferred patent rights to BFX (via two subsidiaries), first in the field of “microchips and processors” and then in “the field of application of the system architecture of supercomputers (High Performance Computing), including cloud computing and the integration of quantum computers in HPC environments”, the set ultimately making BFX “currently responsible for managing, licensing, and enforcing” the patents-in-suit.
