Comcast Corporation et al. v.Entropic Communications LLC

· IPR2024-00435

Comcast Cable Communications challenged Entropic's patent (11381866) in an IPR, asserting that the claims are anticipated or obvious over various prior art references.

The Board has instituted the proceeding based on these compelling unpatentability challenges.

patent instituted · Feb 16, 2024

Comcast Corporation et al. v.Entropic Communications LLC

· IPR2024-00441

The PTAB institution decision found that the Petitioner successfully demonstrated unpatentability of numerous claims under 35 U.S.C. § 103. The Board relied heavily on combinations of prior art references, notably Kamieniecki and Konstantinos, to support its findings against the patent owner. This outcome significantly strengthens the petitioner's position in the ongoing litigation.

patent denied · Feb 16, 2024

Comcast Corporation et al. v.Entropic Communications LLC

· IPR2024-00437
