Red Hat (5:24-cv-00505), acquired by IBM in 2019, has filed an Eastern District of North Carolina complaint against Competitive Access Systems, Inc. (CAS), asserting a claim under that state’s bad-faith patent assertion law, the North Carolina Abusive Patent Assertion Act (APAA), and seeking a judgment of noninfringement for its Linux products. The seven patents at issue broadly relate to networking, including network path optimization, bandwidth sharing, and/or multiple links between a source and destination for bonded data transmission.
