Samsung Electronics Co. Ltd. et al. v.Maxell, Ltd.
Samsung Electronics challenged Maxell's patent covering multi-radio cellular functionality, simultaneous video/data transfer, and over-the-air updates. The petition argues these features were obvious combinations of prior art references like N93 and Dua. This IPR targets 27 claims across five distinct grounds.
Reed Semiconductor Corporation v.Monolithic Power Systems, Inc.
Reed Semiconductor Corporation challenged Monolithic Power Systems' '608 Patent, asserting that claims related to bootstrap refresh control circuits for DC-DC voltage converters are invalid under 35 U.S.C. §§ 102 and 103. The petitioner relies heavily on prior art references, including TI data sheets and patents by Galinski, Li, and Wong, to demonstrate anticipation and obviousness.
Dyson Technology Limited et al. v.Omachron Intellectual Property Inc. et al.
Dyson successfully had its patent (No. 11,389,038 B2) instituted in an IPR against Omachron Intellectual Property Inc., overcoming initial challenges regarding obviousness. The Board found a reasonable likelihood of success for Dyson across all asserted claims (1-15), moving the dispute toward trial.
Duration Media v.Rich Media Club LLC
The PTAB denied the institution of Inter Partes Review (IPR) against Rich Media Club LLC's advertising patent. The Board found that Petitioner Duration Media lacked a reasonable likelihood of prevailing on grounds of obviousness (103).
fuboTV Media Inc. et al. v.DISH Technologies L.L.C. et al.
fuboTV and Yanka Industries successfully petitioned to institute an IPR against DISH Technologies L.L.C.'s patent (8868772) covering Adaptive Bitrate Streaming technology. The Board found a reasonable likelihood of prevailing on obviousness grounds over prior art references Leaning and Gamble, leading to the institution of all 21 challenged claims.
fuboTV Media Inc. et al. v.DISH Technologies L.L.C. et al.
fuboTV Media Inc. successfully convinced the PTAB to institute an IPR against DISH Technologies L.L.C.'s adaptive bitrate streaming patent (10757156). The Board found that the petitioner showed a reasonable likelihood of prevailing on obviousness grounds over prior art references Leaning and Ala-Honkola. This sets up a high-stakes challenge to core technology in digital media streaming.
fuboTV Media Inc. et al. v.DISH Technologies L.L.C. et al.
fuboTV Media Inc. successfully petitioned the PTAB to institute an IPR against DISH Technologies L.L.C.'s patent, challenging claims related to adaptive bitrate streaming technology. The Board found a reasonable likelihood of prevailing on multiple grounds of obviousness over prior art references Leaning and Gamble. This decision moves the dispute toward a full trial.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology, Inc. lost its request for rehearing after the PTAB denied institution of IPR against Yangtze Memory Technologies Company regarding NAND Flash memory patents.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology failed to invalidate Yangtze Memory Technologies' patent on obviousness grounds in a PTAB IPR decision. The Board found that the petitioner could not demonstrate that combining prior art teachings would render the claimed 3D Flash memory invention obvious.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology's request for rehearing of the institution denial in its IPR against Yangtze Memory was denied by the PTAB. The Board upheld its construction of key terms, finding no abuse of discretion.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology's IPR petition against Yangtze Memory Technologies regarding NAND flash technology was denied by the PTAB. The Board rejected arguments concerning claim scope, specifically finding that 'dummy source structure' must not function as a memory cell source.
Samsung Electronics Co. Ltd. et al. v.Maxell, Ltd.
Samsung successfully secured institution in this IPR against Maxell, challenging numerous claims of patent 11445241. The Board found sufficient evidence regarding prior art combinations involving N93, Dua, and Herle. This decision moves the dispute toward a full trial on obviousness grounds.
Reed Semiconductor Corporation v.Monolithic Power Systems, Inc.
The PTAB denied institution for Reed Semiconductor Corporation's IPR against Monolithic Power Systems, Inc., finding Petitioner failed to adequately map claims onto prior art references. The denial was based on insufficient explanation regarding specific functional limitations in the voltage converter technology.
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.
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 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. v.DISH Technologies L.L.C. et al.
The PTAB held that many claims of the ’555 adaptive‑rate streaming patent are obvious over prior art (Ogdon, Allen, and SMIL 2.0), rendering them unpatentable, while other claims remain valid.
fuboTV Media Inc. v.DISH Technologies L.L.C. et al.
The PTAB held that 17 of the 25 challenged claims of DISH’s adaptive‑bitrate streaming patent are obvious over prior art, while 8 claims survive. The decision affirms most of fuboTV’s objections but leaves several claims intact.
fuboTV Media Inc. v.DISH Technologies L.L.C. et al.
The PTAB held 16 of the 25 challenged claims of DISH’s adaptive‑rate streaming patent unpatentable as obvious over Ogdon and Allen, with two additional claims invalidated over Ogdon, Allen, and SMIL 2.0. The remaining nine claims were upheld.
fuboTV Media Inc. v.DISH Technologies L.L.C. et al.
The PTAB denied fuboTV Media’s request for rehearing of the final written decision in IPR2024-00046, finding no error in the Board’s claim construction or consideration of prior art. The petition’s arguments on claim 7 were deemed untimely and unsupported.
fuboTV Media Inc. v.DISH Technologies L.L.C. et al.
The PTAB denied fuboTV's request for rehearing of its IPR decision on patent 11,677,798. The Board held that the petitioner failed to show any misapprehension of prior‑art mappings or erroneous claim construction, leaving the earlier mixed result unchanged.
fuboTV Media Inc. v.DISH Technologies L.L.C. et al.
The USPTO denied fuboTV Media Inc.'s request for Director Review of the Final Written Decision in several IPRs against DISH Technologies patents.

The PTAB held that claims 1–3,5,16–20,22,26–28,30 of U.S. Patent 10,469,554 are obvious over prior art (Ogdon, Allen, and SMIL 2.0) and thus unpatentable, while claims 4,7,8,10–14,23–25 remain valid.
fuboTV Media Inc. v.DISH Technologies L.L.C. et al.
The PTAB denied fuboTV’s request for Director Review of the Final Written Decision in IPR2024-00902 and related IPRs, leaving the original decisions intact.
