The PTAB denied Optronic Sciences' request to reconsider the institution decision in IPR2024‑01133, finding no extraordinary circumstances despite recent guidance changes. The Board applied the Chief Judge’s and Director’s memoranda and upheld the original institution.
BOE Technology Group Co., Ltd. v.Optronic Sciences LLC
BOE Technology Group and Optronic Sciences settled their IPR dispute over U.S. Patent 7,226,801 B2. The Board terminated the proceeding by joint motion, citing good cause and confidentiality considerations.

The PTAB instituted inter partes review of DISH Technologies' adaptive‑bitrate streaming patent (claims 1‑16) and granted joinder to Webgroup Czech Republic and NKL Associates, aligning the case with the earlier fuboTV/MasterClass IPR.
Meta Platforms, Inc. v.SitNet, LLC
The PTAB held that Meta Platforms' petition proved all 20 claims of SitNet’s ’682 patent obvious over Burfeind and Crowley, rendering the claims unpatentable.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
The PTAB issued a final decision finding all 10 claims unpatentable based on obviousness over prior art references Li and Wu. The Board adopted the Petitioner's definition of 'domain,' which was crucial to establishing the combination of teachings from both sources.
Meta Platforms, Inc. v.Sitnet, LLC
The PTAB issued a final decision finding all 20 claims of the patent unpatentable over a combination of Burfeind and Crowley. The Board adopted the petitioner's argument that the challenged claims were obvious, specifically noting that Crowley provided motivation to integrate location-based features into Burfeind's event management system.
Meta Platforms, Inc. v.Sitnet, LLC
The PTAB issued a Final Written Decision finding that the patent claims were unpatentable by a preponderance of the evidence. The Board found obviousness over single and combined prior art references (Gage/Mitchell) for original claims, and also determined substitute claims failed both 103 and 101 standards.
Juniper Networks, Inc. v.Monarch Networking Solutions LLC
The PTAB issued a Final Written Decision finding that claims 1 and 6 of the patent were unpatentable over prior art references Wainner and Bocci. The Board agreed with the Petitioner's argument that combining these references rendered the claimed method obvious, particularly regarding shared link functionality in pseudo-wires.
Microsoft Corporation v.Proxense, LLC
The PTAB found all nine challenged claims unpatentable over the combination of Giobbi ’1573, Giobbi ’1394, and Dua. The Board successfully rejected arguments regarding means-plus-function interpretation, finding key terms like 'PDK' and 'RDC' conveyed sufficient definite structure. This decision represents a significant win for the Petitioner in this IPR proceeding.
Google LLC v.Proxense, LLC
The Board found all challenged claims unpatentable, primarily based on obviousness (35 U.S.C. § 103). The Petitioner successfully demonstrated that the claimed hybrid device and its methods were predictable combinations of prior art references like Buer, Lee, Nishikawa, and Dua.
Google LLC v.Proxense, LLC
The PTAB found all 20 challenged claims unpatentable over various combinations of prior art references. The Board adopted the Petitioner's view that the terms used in the patent provided sufficiently definite structure and that the combination of existing technology rendered the claimed invention obvious.
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.
fuboTV Media Inc. et al. v.DISH Technologies L.L.C. et al.
The PTAB found all 18 challenged claims unpatentable over prior art combinations, primarily Leaning. The Board determined that Leaning discloses key adaptive bitrate streaming features, including methods for segmenting video and implementing rate switching based on network performance factors.
fuboTV Media Inc. et al. v.DISH Technologies L.L.C. et al.
Petitioner successfully demonstrated that all 16 claims of the '564 patent are unpatentable over prior art, primarily Leaning. The Board construed 'continuous playback' to mean no interruption occurs between files during a rate shift, finding this limitation was taught by Leaning.
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.
Aylo Freesites Ltd et al. v.DISH Technologies L.L.C. et al.
The PTAB found that claims 1-11 of the patent were unpatentable over prior art references (Leaning, Klemets, Gamble) based on obviousness under 35 U.S.C. § 103. The Board adopted a limiting construction for 'to achieve continuous presentation,' requiring uninterrupted playback across quality shifts.
BOE Technology Group Co., Ltd. v.Optronic Sciences LLC
The PTAB issued a Final Written Decision finding claims 5 and 6 of patent 7168842 unpatentable based on anticipation (Uekusa) and obviousness (Uekusa/Isoda). Claims 7-9 were not proven unpatentable due to claim clarity issues.
BOE Technology Group Co., LTD v.Optronic Sciences LLC
The Board found all seven challenged claims unpatentable, rejecting the patent owner's narrow construction of 'passivation layer.' The petitioner successfully demonstrated that combining prior art references (Anzai and Yamazaki) taught or rendered obvious the claimed invention in OLED devices.
BOE Technology Group Co., LTD v.Optronic Sciences, LLC
The PTAB issued a Final Written Decision finding all 13 claims unpatentable by preponderance of the evidence. The Board found that the challenged claims were obvious over various combinations of prior art references, including Weaver combined with Lee ’053 and Song.
Kia Corporation et al. v.Emerging Automotive LLC
The PTAB found that the majority of claims (1-5 and 7-21) in the '659 patent were unpatentable based on combinations of prior art references. The Board specifically agreed with Petitioner's argument that Kleve combined with Hatton rendered independent claim 1 obvious, finding a reasonable expectation of success for POSITA.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures I LLC et al.
The PTAB found that claims 1 and 3-7 of the patent were unpatentable over prior art references (Shenai, Georgiou, etc.), while claims 8-12 survived. The key finding was that the claim language did not require global-asynchrony, supporting the Petitioner’s interpretation.
Genius Sports Ltd. v.SportsCastr Inc.
The PTAB found claims 1-7 unpatentable over a combination of Ellis, Spivey, and Herzog, concluding that the claimed live video streaming system was obvious to a POSA. The Board specifically held that Spivey's topic queues satisfy the definition of an 'event socket.'
Genius Sports Ltd. v.SportsCastr Inc.
The PTAB found that claims 19-25 and 27-30 of the '687 patent were unpatentable over a combination of Ellis and Spivey, based on obviousness (Ground 1). The Board rejected an alternative ground involving Herzog, finding no motivation to combine those references.
Genius Sports Ltd. v.SportsCastr Inc.
The PTAB issued a Final Written Decision finding all nine challenged claims unpatentable over combinations of prior art references (Ellis, Spivey, Herzog). The Board relied heavily on the combination of Ellis and Spivey to establish obviousness for Claim 1, particularly regarding low-latency data delivery via uniquely addressable event sockets.
Genius Sports Ltd. v.SportsCastr Inc.
The PTAB found that the challenged claims were unpatentable by a preponderance of evidence, rejecting the Patent Owner's arguments against obviousness. The decision centered on whether prior art references (Ellis and Spivey) combined could teach all limitations of the claimed system for live event broadcasting.
Genius Sports Ltd. v.SportsCastr Inc.
The PTAB issued a Final Written Decision finding all 15 challenged claims unpatentable as obvious over combinations of prior art. Petitioner successfully demonstrated that combining Ellis and Spivey taught an 'event socket' to improve latency, while other grounds were also met by the combination of Ellis, Spivey, and Herzog.
