Google LLC et al. v.HEADWATER RESEARCH LLC
The PTAB held that claims 1‑17, 19, 21‑27, 29 and 30 of Headwater Research’s ’733 patent are unpatentable. Google and Samsung successfully proved obviousness over the MMS 3GPP spec and the Ogawa encryption device.
AT&T Corp et al. v.Daingean Technologies Ltd.
The Board issued a Final Written Decision finding all challenged claims unpatentable. The patent relates to random access procedures in LTE/5G apparatuses and involved significant claim construction regarding power ramping functions.
Samsung Electronics Co., Ltd. et al. v.Headwater Research LLC
The Board found all challenged claims of patent 8406733 unpatentable over prior art references TS-23.140 and Ogawa by a preponderance of the evidence. The decision hinged on demonstrating that conventional design choices, such as using SSL/TLS and implementing modems, would have been obvious to one skilled in the art.
AT&T Corp. et al. v.Daingean Technologies Ltd.
The PTAB granted the Patent Owner's revised motion to amend claims 7 and 8, replacing original claims 1-4. The Board found that these substitute claims did not introduce new matter or enlarge the scope of the patent, successfully defeating the Petitioner’s anticipation and obviousness arguments.
Visa, Inc. v.Cortex MCP, Inc.
The PTAB Board upheld the validity of Cortex MCP's claims (1-17) related to electronic credentials and tokenization. The Board rejected arguments that the claimed features were obvious over prior art references like Oborne, Neafsey, and Stafford.
Visa, Inc. v.Cortex MCP, Inc.
The Board found that the majority of claims (24 out of 33) were unpatentable over various combinations of prior art references. The key finding was that Oborne teaches core tokenization elements, while other combinations failed to provide sufficient motivation for the claimed improvements.
Visa, Inc. v.Cortex MCP, Inc.
The PTAB found most claims of the '859 patent unpatentable based on obviousness (103). The Board adopted Petitioner's view regarding the level of ordinary skill in the art and construed key terms like 'OVER file.' Claims 2, 10, 19, and 21 survived the challenge.
Visa, Inc. v.Cortex MCP, Inc.
The PTAB found numerous claims of U.S. Patent No. 11329973 unpatentable based on obviousness (103). The Board determined that the prior art, particularly Oborne, discloses key limitations related to token generation and issuing agency verification in digital credential systems. Claims 1, 3–8, and 10–16 were found invalid, while claims 2, 9, and 17 survived.
Intel Corporation et al. v.TELEFONAKTIEBOLAGET L M ERICSSON et al.
The PTAB found multiple claims of the '430 patent unpatentable over prior art, primarily Taniguchi. The Board adopted Petitioner's construction that key claim terms were not limiting, supporting obviousness findings across several grounds.
Cisco Systems, Inc. v.Lionra Technologies Limited
The PTAB found claims unpatentable under 35 U.S.C. § 103(a) based on a combination of prior art references (Gai, Yip, Kwan, and Georgiou). The Board determined that an ordinary skilled artisan would have been motivated to combine these teachings to enhance network security and implement advanced ACL functions.
TESLA, INC. v.Autonomous Devices, LLC
The PTAB issued a Final Written Decision finding that several original claims were unpatentable over Buibas in view of Sinyavskiy. However, the Board subsequently found the petitioner's substitute claims obvious over combinations of Grotmol and Zhu prior art, leading to further rejection.
Cellco Partnership d/b/a Verizon Wireless et al. v.Headwater Partners I LLC
The Board found all 18 challenged claims unpatentable under 35 U.S.C. § 103 (obviousness). The Petitioner successfully argued that the combination of prior art references, including Limont, Wright, and Xu, disclosed the claimed invention. This final decision provides a strong defense against infringement claims in wireless communications technology.
Charter Communications, Inc. v.Iarnach Technologies Limited
The PTAB issued a Final Written Decision finding Claim 5 unpatentable over Bernstein and Tsuge based on obviousness (103). Claims 1-3 and 6-11 were found patentable, despite extensive claim construction disputes regarding 'service auto-configuration method.'
Cisco Systems, Inc. v.Lionra Technologies Limited
The PTAB found the claims unpatentable under 35 U.S.C. § 103 because they were obvious in light of prior art references (Cornett, Paatela, Nelson, Russell). The Board adopted a construction of 'concurrently writing' that aligned with both parties and district court precedent. Petitioner successfully demonstrated that the combination of disclosures taught all limitations of the claims for high-speed packet processing.
QUALCOMM INCORPORATED et al. v.COBBLESTONE WIRELESS, LLC,
The PTAB found several claims unpatentable based on obviousness (35 U.S.C. § 103) using various prior art combinations in the field of multi-carrier communication systems. The Board adopted a broad construction of 'information' as 'data,' which was critical to its findings against the Patent Owner.
BMW of North America, LLC et al. v.Foras Technologies Limited
BMW challenged claims of Foras Technologies' patent related to switching the boot processor role in multi-processor systems. The PTAB issued a Final Written Decision finding that the petitioner failed to prove unpatentability over prior art references.
BMW of North America, LLC et al. v.Foras Technologies Limited
The PTAB issued a Final Written Decision rejecting all claims of the '781 patent based on obviousness (35 U.S.C. § 103). The Board found that while prior art references describe processor swapping or task management, they fail to teach the specific transfer of the 'role' of boot processor during runtime as claimed.
Visa, Inc. v.Cortex MCP, Inc.
Visa, Inc., successfully petitioned for institution in a high-stakes IPR against Cortex MCP, Inc.'s digital credentialing patent (9251531). The Board adopted key claim constructions favorable to the Petitioner and found sufficient evidence of obviousness based on prior art references.
