Short Summary
The PTAB found that all 21 challenged claims of DISH Technologies L.L.C. were unpatentable by a preponderance of the evidence. The Board determined that prior art, specifically Leaning and Gamble, taught or rendered the claimed Adaptive Bitrate Streaming (ABR) technology obvious.
Detailed Summary
In this final written decision, the Patent Trial and Appeal Board ruled in favor of the Petitioner, establishing the unpatentability of claims 1 through 21. The central finding was that the prior art reference Leaning disclosed all limitations of Claim 1, including continuous playback and utilizing multiple TCP connections for rate-adaptive shifting. Furthermore, the combination of Leaning and Gamble rendered Claims 2 and 9 obvious. The Board discounted the Patent Owner's secondary considerations arguments (e.g., commercial success) due to a lack of nexus with the claimed invention, concluding that the prior art fully supported the technology in question.
