Context:
- German supercomputer firm ParTec and its licensing agent BF exaQC, run by famous former patent litigator and patent monetizer (IPCom) Bernhard Frohwitter, sued Microsoft (in the U.S.) and NVIDIA (in the UPC) over supercomputer patents.
- The UPC’s Munich Local Division (LD) sided with NVIDIA in one case (March 11, 2026 ip fray article). That decision has since been appealed.
- ParTec’s lawsuit against Microsoft in the United States District Court for the Eastern District of Texas, however, was on the winning track and led to a presumably lucrative settlement (May 12, 2026 ip fray article).
- Last month, a ParTec complaint against Lenovo (a major player in high-perfomance computing) was filed with the UPC’s Dusseldorf LD.

It appears that the counsel of record in ParTec’s new actions (also the case against Lenovo as well as the NVIDIA appeal) is Frohwitter Intellectual Property Counselors‘ Iram Kamal. The lead patent attorney on the Lenovo complaint and the NVIDIA appeal is IPCGS’s Jan Gigerich (who used to work at the Frohwitter firm and is also involved with the NVIDIA litigation). We have not found out yet who the lead patent attorney on the Google and AMD cases is.
