Charter Communications, Inc. v.Iarnach Technologies Limited
The PTAB instituted the IPR for Charter Communications against Iarnach Technologies, finding sufficient evidence that claims of Patent No. 9287982 are obvious over various prior art references (Bernstein, Tsuge, MEF 6.1). The Board addressed numerous claim construction issues, confirming some preambles were limiting while others were not.
Charter Communications, Inc. v.Iarnach Technologies Limited
Charter Communications, Inc. failed to invalidate 13 claims covering Passive Optical Networks (PON) and multicast encryption technologies before the PTAB. The Board denied institution based on insufficient evidence showing obviousness over prior art including RFCs and Murakami.
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.'
Nikon Corporation et al. v.Optimum Imaging Technologies LLC
Nikon and other camera manufacturers settled with Optimum Imaging Technologies, leading the PTAB to terminate the inter partes review of patent 8,451,339 and related patents. The settlement agreement is confidential under statutory provisions.
Nikon Corporation et al. v.Optimum Imaging Technologies LLC
The PTAB granted institution of trial in this IPR concerning digital camera image processing and aberration correction. The Board found sufficient likelihood of unpatentability based on obviousness arguments combining prior art references (Niikawa and Enomoto).
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.
Olympus Corporation et al. v.Optimum Imaging Technologies LLC
The PTAB denied Optimum Imaging’s request for rehearing of the institution decision in IPR2024-01220, keeping the review of the Olympus‑related lens‑correction patent alive. The Board found no abuse of discretion and rejected the discretionary denial argument under § 314(a).
Olympus Corporation et al. v.Optimum Imaging Technologies LLC
Olympus and other camera makers settled with Optimum Imaging Technologies, leading to the termination of four inter partes review proceedings covering patent 10,873,685. The Board granted the joint motion to terminate and ordered the settlement agreement to be kept confidential.
Olympus Corporation et al. v.Optimum Imaging Technologies LLC
Olympus Corporation et al. successfully navigated the institution phase in an IPR against Optimum Imaging Technologies, LLC regarding imaging systems technology. The Board preliminarily found a reasonable likelihood of unpatentability based on multiple grounds of obviousness (103).
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.
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.
Cisco Systems, Inc. v.Lionra Technologies Limited
Cisco Systems successfully petitioned to institute IPR against Lionra Technologies regarding patent 7,738,471, challenging claims related to high-speed packet header processing.
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.
Ubiquiti Inc. v.Intellectual Ventures I
Ubiquiti Inc.'s IPR challenge against Intellectual Ventures I LLC was denied by the PTAB. The Board found that Petitioner failed to demonstrate a reasonable likelihood of success, particularly regarding the key SIFS limitation in wireless communication claims.
Cisco Systems, Inc. v.Croga Innovations Ltd.
Cisco Systems and Croga Innovations settled their IPR dispute over U.S. Patent 7,738,368. The parties filed a joint motion to terminate the proceeding, and the Board granted the termination.

FUJIFILM Corporation et al. v.Optimum Imaging Technologies LLC
The PTAB instituted the IPR on all 30 challenged claims for FUJIFILM Corporation et al. against Optimum Imaging Technologies LLC, finding a reasonable likelihood of unpatentability over Sarbadhikari and Katagiri. The decision was based on Petitioner's diligent filing and favorable factors regarding parallel district court litigation despite Patent Owner arguments to the contrary.
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.
Cisco Systems, Inc. v.Croga Innovations Ltd.
Cisco Systems' IPR challenge against Croga Innovations regarding network security claims was denied by the PTAB. The Board found that the cited prior art did not teach or suggest the critical 'internal firewall' limitations required by the patent claims.
