Samsung Display Co., Ltd. et al. v.Pictiva Displays International Ltd.
Samsung Display Co., Ltd.'s IPR petition against Pictiva Displays International Ltd. was denied by the PTAB. The Board found that the petition lacked compelling merits and determined the dispute was better suited for District Court resolution due to complex claim construction issues.
Microsoft Corporation v.Proxense, LLC
The PTAB issued a Final Written Decision finding all 29 challenged claims unpatentable over the prior art. The Board found that Burger teaches limitations of Claim 1 across various transaction types, and combining Burger with Robinson or Orsini renders dependent claims obvious.
Ilooda Co., Ltd. et al. v.Serendia, LLC
Ilooda Co. challenges Serendia's patent (10869812) in an IPR based on anticipation and obviousness, focusing on microneedling technology. The petitioner argues that prior art references like Mehta render multiple claims unpatentable through various combinations of elements.
fuboTV Media Inc. et al. v.DISH Technologies L.L.C. et al.
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.
Apple Inc. v.Varia Holdings LLC
The PTAB found all 39 claims of patent 8127984 unpatentable under 35 U.S.C. § 103(a). The Board concluded that the claimed 'functional emulation' was obvious when combining prior art references like Willgert and Mooney.

Dental Imaging Technologies Corporation's IPR petition against 3Shape A/S was denied institution by the PTAB. The Board found that despite some arguments, the similarities to prior proceedings and resource constraints warranted denial under discretionary authority.
