Late last year, Omni MedSci, Inc. filed a single Eastern District of Texas complaint against Fossil, OnePlus, Oura Health, and Samsung, alleging infringement of five patents from a large family that names University of Michigan professor Mohammed N. Islam as the sole inventor. Another member of that family issued in January, prompting a March amended complaint in that case. Now, Omni MedSci has filed a second case against the same four defendants in the same district (2:25-cv-00483), asserting the most recent patent to issue in the family, which did so in April. Prosecution of many related applications continues before the USPTO.
