patent final · Apr 29, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00792

The PTAB issued a Final Written Decision denying the petitioner's arguments that claims 1-6 of patent 11468957 were unpatentable. The Board found the anticipation argument failed because Suzuki did not disclose a distinct 'pre-verify stage,' and obviousness arguments failed due to insufficient establishment of required elements over prior art combinations.

patent denied · Apr 26, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00793

The PTAB denied Micron Technology's IPR challenge against Yangtze Memory Technologies regarding NAND Flash patents, finding insufficient evidence to prove obviousness over the cited prior art (Seo and Choi).

patent denied · Apr 26, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00793

The PTAB denied Micron Technology's request for rehearing after institution was previously denied on claims of the NAND Flash patent 11,600,342. The Board found that Petitioner failed to provide objective evidence demonstrating how prior art references inherently teach fast charge removal.

patent instituted · Apr 18, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00789

Micron Technology successfully challenged Yangtze Memory Technologies' patent claims in a PTAB institution decision. The Board adopted a narrow construction of 'dummy source structure,' finding that the Petitioner met its burden for obviousness over Tessariol and Park. This paves the way for further litigation against the patent owner.

patent instituted · Apr 18, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00790

Micron Technology successfully challenged Yangtze Memory Technologies' patent claims in a PTAB Institution Decision regarding obviousness over Kim and Tessariol. The Board adopted the Petitioner's definition of 'surrounding' as 'encircling,' finding a reasonable likelihood that Micron will prevail against the patent.

patent Final Written Decision · Apr 18, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00790

The PTAB issued a Final Written Decision finding claims 1-3 unpatentable over Kim due to obviousness (103), while claims 4 and 5 were found patentable. The Board construed the key term 'surrounding' as meaning 'all around' or 'encircling.'

patent final · Apr 18, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2024-00789

The PTAB found claims 1–6 and 11–13 unpatentable over Tessariol, while finding them patentable over Park. The Board's decision hinged on claim construction, specifically defining 'dummy source structure' as one that does not function as a source to memory cells. This outcome significantly impacts the validity of the asserted claims in 3D Memory Devices (NAND).

patent denied · Apr 10, 2024

Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.

· IPR2025-00005

The PTAB denied the IPR petition against claims 1-4 of U.S. Patent No. 9,457,541, finding that the combination of prior art references did not render the copper foil obvious. The Board ruled that the petitioner failed to demonstrate a reasonable expectation of success when combining properties from materially different sources.

patent denied · Apr 10, 2024

Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.

· IPR2025-00005

Solus Advanced Materials Co., Ltd.'s request for rehearing was denied by the PTAB, upholding the initial decision to deny institution of IPR against SK nexilis's copper foil patent.

patent terminated or settled · Mar 15, 2024

Capital One, National Association et al. v.--

· IPR2024-00643

Hulu and Capital One settled their dispute with patent owner Implicit over U.S. Patent 8,056,075 B2. The PTAB granted a motion to terminate the IPR and ordered the settlement agreements kept confidential.

patent Final Written Decision · Feb 28, 2024

Teladoc Health, Inc. v.Data Health Partners, Inc.

· IPR2024-00616

The PTAB issued a Final Written Decision finding that numerous claims of the patent were unpatentable based on obviousness. The Petitioner successfully demonstrated that various combinations of prior art references rendered the claimed features predictable to one skilled in the art.

patent final · Feb 23, 2024

Air Products and Chemicals, Inc. v.EVONIK OPERATIONS GMBH et al.

· IPR2024-00611

The IPR petition against EVONIK's gas separation membrane technology failed as the Petitioner could not establish unpatentability. The Board found that the combination of cited prior art references lacked a sufficient motivation to combine, upholding the patent's validity.

patent instituted · Feb 12, 2024

Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.

· IPR2025-00191

Micron Technology successfully challenged several claims in the NAND Flash patent, establishing a reasonable likelihood of prevailing on its obviousness grounds. The Board found that modifying TAC shapes and implementing dummy channels were simple advancements supported by prior art.

patent terminated or settled · Feb 5, 2024

Capital One, National Association v.--

· IPR2024-00878

Capital One and Implicit, LLC settled their IPR dispute over a payment‑card fraud patent, leading the PTAB to terminate the proceeding before a trial was instituted.
