The Japan Intellectual Property High Court has affirmed the revocations of two patents, JP6768017 and JP6768110, owned by Xylene. The two patents are related to patents purportedly essential to HEVC Advance patent pool and SISVEL’s VP9 and AV1 patent pools.

Unified was represented by Ace-ai IP Law Firm in Japan, and by in-house counsel, Jessica L.A. Marks.
