MOTOROLA SOLUTIONS, INC. et al. v.Stellar, LLC
The PTAB instituted the IPR for 9912914, finding a reasonable likelihood of success on all challenged obviousness grounds (103). The petitioner argued that combinations of prior art references—including Yerazunis, Fiore, Ely, and Lewellen—would render claims 1-23 obvious to a POSITA.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures I LLC

Charter Communications, Inc. et al. v.Touchstream Technologies, Inc.
The PTAB denied Charter Communications' IPR petition against Touchstream Technologies, citing failure to demonstrate a reasonable likelihood of prevailing on unpatentability grounds and procedural bar under 35 U.S.C. § 315(b).

Samsung Electronics America, Inc. et al. v.Collision Communications, Inc.
The PTAB denied the IPR petition filed by Samsung against Collision Communications' patent covering Multiuser Detection (MUD) technology. The Board found the petitioner failed to demonstrate that the prior art adequately taught the claimed unique signal parameters, leading to a lack of particularity in the arguments.

The Director granted review and vacated institution decisions in multiple IPRs involving Motorola Solutions and Stellar, ultimately denying the petitions.
Motorola Solutions, Inc. et al. v.Stellar, LLC
Motorola Solutions successfully petitioned the PTAB for institution of IPR against Stellar, LLC's patent (8310540), challenging all 19 claims based on obviousness. The Board found a reasonable likelihood that combining prior art references like Yerazunis and Fiore would render the claimed features unpatentable.

The Director of the USPTO denied institution for several IPRs involving Motorola and Stellar, vacating prior Board decisions. The denial was based on changes in circumstances regarding related proceedings and the applicability of new guidance.

Google LLC v.DH International Ltd.
Google LLC successfully petitioned the PTAB to challenge DH International Ltd.'s patentability, leading the Board to institute IPR proceedings on all 20 claims. The Board adopted a broad construction of 'activation cue' favorable to Google and found that the Petitioner met the standard for institution based on obviousness grounds over prior art references Mooney and Lee.
QUALCOMM INCORPORATED et al. v.COBBLESTONE WIRELESS, LLC,
Qualcomm successfully secured institution for its IPR against Cobblestone Wireless, despite the petition being substantively identical to a previously instituted Samsung proceeding. This decision emphasizes that lack of 'road-mapping' alone is insufficient grounds for discretionary denial when the claims are highly relevant.
Samsung Electronics Co., Ltd. et al. v.Headwater Research LLC
The PTAB institution decision allows Samsung Electronics Co., Ltd. to challenge 30 claims of U.S. Patent No. 8,588,110 B2 based on obviousness (35 U.S.C. § 103). The Board adopted the Petitioner's view of the level of ordinary skill in the art and conducted claim construction for key 'means for' limitations. This sets the stage for a full IPR review against Headwater Research LLC.
Samsung Electronics Co., Ltd. et al. v.Secure Wi-Fi LLC
Samsung Electronics sought to invalidate Secure Wi-Fi LLC's patent (9717005) via IPR, alleging obviousness in Wi-Fi network security claims. The PTAB denied institution under 35 U.S.C. § 314(a), finding that factors weighed against proceeding despite the petitioner's arguments.
Samsung Electronics Co., Ltd et al. v.Secure Wi-Fi LLC

The PTAB denied institution of the IPR petition due to concerns over parallel district court litigation and duplicative efforts. The Board found that the central technical issue remained identical, despite petitioner concessions regarding trial timing.
Samsung Electronics Co., Ltd et al. v.Secure Wi-Fi LLC
Samsung's IPR petition against Secure Wi-Fi LLC was denied by the PTAB. The Board determined that the proximity to a parallel district court trial date weighed heavily in favor of discretionary denial under Fintiv factors.

The PTAB granted institution of IPR for Samsung against Headwater, finding a reasonable likelihood that the challenged wireless device claims are unpatentable over Bennett and Vadde.

HP Inc. et al. v.Universal Connectivity Technologies Inc.
The PTAB denied the IPR petition filed by HP Inc. and others against Universal Connectivity Technologies Inc., citing that the petitioner's allegations of anticipation and obviousness were not 'particularly strong.' The decision also addressed discretionary denial under § 314(a) based on parallel district court litigation.
Yealink (USA) Network Technology Co., Ltd. et al. v.Barco N.V.
