patent Final Written Decision

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

· IPR2024-00788

Micron successfully established the unpatentability of five claims (15, 16, 17, 19, and 20) over prior art references Toyama, Mushiga, and Makala. The Board found that various embodiments in the prior art taught all limitations of the challenged claims.

patent final

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 Final Written Decision

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 Written Decision

Micron Technology, Inc. et al. v.YANGTZE MEMORY TECHNOLOGIES COMPANY, LTD.

· IPR2024-00791

The PTAB issued a Final Written Decision denying the Petitioner's challenge to four claims related to 3D memory devices. The Board found that the Petitioner failed to establish obviousness over prior art references, specifically Toyama.

patent final

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 Final Written Decision

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

· IPR2024-00795

The PTAB issued a Final Written Decision finding that the patent claims were unpatentable over combinations of prior art references. Specifically, the Petitioner successfully demonstrated obviousness against Zhao and Lee, leading to the rejection of nearly all challenged claims.

patent final

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

· IPR2024-00794

The PTAB issued a Final Written Decision finding that Claims 1 and 6 were unpatentable over prior art (Park), while the remaining claims were patentable. The Board clarified claim terms like 'formed in the BSG' to encompass both gate-first and gate-last embodiments, rejecting Petitioner’s obviousness arguments based on hindsight bias.

patent final

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

· IPR2024-00911

The PTAB issued a Final Written Decision finding that dependent claim 10 of U.S. Patent No. 10,937,806 was not unpatentable over Toyama. The challenge failed because the Petitioner could not demonstrate obviousness for its base independent claim 8.

patent final

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

· IPR2024-00909

The PTAB found claims 1-7 and 18 unpatentable over the prior art reference Toyama under 35 U.S.C. § 103. The Board issued a Final Written Decision after addressing several key claim construction disputes regarding isolation regions, dielectric structures, and local contacts.

patent denied

Next Step Group, Inc. v.Deckers Outdoor Corporation

· IPR2024-00525

The PTAB denied institution for Next Step Group's IPR against Deckers Outdoor Corporation regarding the Pull Tab Functional '161 patent.

patent denied

NJOY, LLC et al. v.JUUL Labs, Inc.

· IPR2024-00536

The PTAB denied institution of the IPR petition for NJOY against JUUL Labs, finding that Petitioner failed to demonstrate a reasonable likelihood of prevailing on obviousness grounds. The Board found insufficient motivation or reasonable expectation of success in combining various prior art references across multiple claims.

patent denied

NJOY, Inc. v.JUUL Labs, Inc.

· IPR2024-00567

The PTAB denied NJOY's request to challenge JUUL's electronic cigarette patent (RE49114), finding that the Petitioner failed to meet the burden of showing a reasonable likelihood of prevailing on any claim.

patent instituted

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.
