PTAB Rules Against Withrow Networks in Patent Obviousness Case
The Patent Trial and Appeal Board (PTAB) has ruled against Withrow Networks Inc. in an inter partes review, deeming its patent claims unpatentable due to obviousness over prior art.
The challenged claims relate to methods of multimedia transmission and playback for mobile clients.
Google LLC had filed the inter partes review, which led to the PTAB's decision that the claimed innovations are obvious over various combinations of prior art, including network data communications and real-time multimedia broadcasting over a network.
