ParTec AG files patent infringement suit against Microsoft Corporation in Texas, USA with its licensing agent BF exaQC AG

Munich, 10th June 2024

ParTec AG and its licensing agent BF exaQC AG today filed a patent infringement lawsuit in the US against Microsoft Corporation. The core of the legal dispute is the infringement of ParTec patents relating to the dynamic modular system architecture (dMSA) that ParTec developed and uses worldwide in the construction of powerful leading-edge state of the art AI-supercomputers. The lawsuit seeks, among other things, an injunction against the use of the patented technology as well as license fees and compensation for damages.

“Microsoft is infringing our intellectual property with its wave of AI supercomputers as part of their cloud computing platform Azure. We have therefore decided to file a lawsuit in Texas, USA,” explains Bernhard Frohwitter, CEO of ParTec AG and BF exaQC AG.

The two companies hold a total of approximately 150 patents and patent applications worldwide. One of the most important patents is ParTec’s dMSA patent, US Patent 10,142,156. The dynamic Modular System Architecture (dMSA) approach is a unique selling point of ParTec AG. It has proven itself in particular for the complex requirements of massive computing power in artificial intelligence such as AI training and inference and is fundamental for the dynamic interaction of CPUs and GPUs and other processors in supercomputers. Artificial intelligence, or AI, is a term used to describe technology that enables computers to simulate human intelligence and problem-solving skills and push the boundaries of what was previously possible. This requires particularly powerful, modular supercomputers, such as those built by ParTec.

The importance of ParTec AG’s patents is demonstrated by their use in world-leading, modern European supercomputers such as Leonardo in Bologna, JUWELS and JUPITER in Jülich, all of which were built on the basis of dMSA and are internationally regarded as pioneering. In addition, ParTec AG is already in negotiations with a well-known American chip manufacturer for the licensing of patents, as well as in contact with US authorities for use in the world‘s largest exaFlop Supercomputer under construction.  In the past ParTec also licensed the patents in a deal worth millions in Europe for the construction of modular supercomputers.

Leading US law firm Susman Godfrey L.L.P. is representing the ParTec and BF exaQC in this litigation, led by partner Justin Nelson. Susman Godfrey was founded in 1976 and is one of the most successful litigation law firms in the USA. Since the introduction of the Vault Award in 2011, the firm has been voted the No. 1 law firm in the US every year and has had a series of spectacular successes over the last few years.
