AT&T Services Inc. et al. v.ASUS Technology Licensing Inc.
The PTAB Director denied the petitioners’ request for review of the institution decisions in two IPRs involving ASUS patents. The denial leaves the original institution denials in place.
AT&T Services Inc. et al. v.ASUS Technology Licensing Inc.
Petitioners, including AT&T and Verizon, successfully petitioned to challenge 19 claims of Asustek Computer Inc.'s patent regarding physical layer procedures for CORESET management. The PTAB found compelling merits based on multiple grounds of obviousness (35 U.S.C. § 103). This institution sets the stage for a detailed technical battle over wireless standards implementation.
AT&T Services Inc. et al. v.ASUS Technology Licensing Inc.
The PTAB denied the IPR petition, finding that the preliminary record did not present a compelling challenge to the patent's validity despite multiple grounds of obviousness. The Board relied on a holistic review of the Fintiv factors, ultimately favoring discretionary denial under 35 U.S.C. § 314(a).
Uber Technologies, Inc. v.Enovsys, LLC
Uber Technologies filed a Petition challenging the validity of Enovsys's Proximity Alert Patent (6756918) based on obviousness (35 U.S.C. § 103). The petitioner argues that existing prior art, including Layson references and Taylor/Fast teachings, renders the claimed location tracking methods unpatentable. This challenges a key patent in the victim-offender monitoring space.
Panasonic Automotive Systems Co., Ltd. v.UNM Rainforest Innovations
The PTAB denied institution of an IPR challenge against UNM Rainforest Innovations' patent 8265096, finding no reasonable likelihood that the petitioner could prove unpatentability. The denial hinged on the Board's rejection of anticipation arguments based on prior art related to wireless data formats.
T-Mobile USA, Inc. et al. v.Wireless Alliance, LLC et al.
Petitioners T-Mobile USA and AT&T Services challenge four claims of the '662 Patent based on obviousness (35 U.S.C. § 103) and priority date rejection (35 U.S.C. § 102). They argue that combining prior art references Lee et al. and Kim et al. renders the claimed carrier aggregation/HARQ methods obvious. The petition also challenges the patent's priority, arguing lack of support for specific limitations.
T-Mobile USA, Inc. et al. v.Wireless Alliance, LLC et al.
A group of major carriers, including T-Mobile, AT&T, Verizon, Nokia, and Ericsson, challenged the validity of a patent owned by Wireless Alliance using obviousness grounds.

Samsung Electronics America filed a petition challenging the validity of Cobblestone Wireless's '802 patent, asserting that its multi-carrier transmission claims are obvious in light of mid-2000s prior art. The petitioner argues that established technologies like Suzuki and Fernandez render the claimed methods predictable modifications to known systems.
Samsung Electronics America, Inc. et al. v.Cobblestone Wireless LLC
The PTAB institution decision found a reasonable likelihood of success for Samsung Electronics America, Inc. in challenging Cobblestone Wireless LLC's patent (7924802).

Comcast Corporation et al. v.Entropic Communications LLC
Comcast Cable Communications challenged Entropic's patent (11381866) in an IPR, asserting that the claims are anticipated or obvious over various prior art references. The petitioner argues that Zhang anticipates key features and combinations of Zhang with Reisman, Jackson, and Pandey render other claims obvious. The Board has instituted the proceeding based on these compelling unpatentability challenges.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB institution decision found that the Petitioner successfully demonstrated unpatentability of numerous claims under 35 U.S.C. § 103.

This outcome significantly strengthens the petitioner's position in the ongoing litigation.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB denied Comcast's request to institute an IPR against Entropic's patent, citing the existence of a parallel petition. The Board determined that one petition was sufficient and denying the second would prevent unnecessary burden.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB instituted the IPR, finding a reasonable likelihood of prevailing for Comcast's claims against Entropic Communications. The grounds centered on anticipation and obviousness using prior art references like Zhang, Reisman, Jackson, and Pandey.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB denied Comcast's request to institute IPR against Entropic's wideband tuner patent (9210362) because the petitioner had filed a parallel petition on the same claims.
