Short Summary
Amazon challenged Nokia's video coding patent (11805267) before the PTAB, arguing that the claimed methods are obvious over prior art references. The Board denied the petition, finding no basis for discretionary denial under §325(d).
Detailed Summary
Amazon filed an IPR challenging Nokia Technologies Oy's patent 11805267 related to video coding/compression (H.264). Amazon asserted multiple grounds of obviousness (§103), citing references such as Walker and the Karczewicz series. The petitioner argued that a Person Having Ordinary Skill In The Art (POSITA) would have been motivated to combine known elements from these prior art sources—specifically combining bi-directional prediction with high-precision interpolation techniques—to improve prediction accuracy. However, the Board ultimately denied the petition, concluding that discretionary denial was not warranted under §325(d).
