Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology successfully secured institution at the PTAB against Yangtze Memory Technologies regarding claims related to 3D memory devices. The Board found sufficient evidence for unpatentability under both §102 and §103 over prior art references Toyama, Mushiga, and Makala.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology successfully petitioned the PTAB to challenge Yangtze Memory Technologies' patent claims related to 3D-NAND memory operation, leading to the institution of the IPR. The Board found a reasonable likelihood that Micron would prevail on its challenges regarding anticipation and obviousness over multiple prior art references.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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).
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.'
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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).
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled their inter partes review dispute over U.S. Patent 11,212,146. The Board granted the parties' joint motions to terminate the IPRs and treated the settlement agreement as confidential.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled their dispute, leading to the termination of eight inter partes review proceedings covering patents on wireless networking. The Board granted the parties' joint motions to terminate and treated the settlement agreements as confidential.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled eight inter partes review proceedings before they were instituted. The Board granted the parties' joint motions to terminate and treated the settlement agreement as confidential.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled eight inter partes review proceedings covering wireless patents. The Board granted joint motions to terminate the IPRs and treated the settlement agreements as confidential.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled eight inter partes review proceedings before any trial was instituted. The Board granted the joint motions to terminate and treated the settlement agreements as confidential.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled their dispute, leading the PTAB to terminate eight inter partes review proceedings, including the IPR challenging patent 10,291,449 B2, before any trial was instituted.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled eight inter partes review proceedings covering wireless patents. The Board granted termination motions and treated the settlement agreements as confidential.
DELL INC. et al. v.AX Wireless, LLC et al.
Dell and AX Wireless settled eight IPRs before they were instituted, leading the PTAB to terminate the proceedings and keep the settlement agreements confidential.
Micron Technology, Inc. et al. v.YANGTZE MEMORY TECHNOLOGIES COMPANY, LTD.
Micron Technology challenged YANGTZE MEMORY TECHNOLOGIES COMPANY over its 3D NAND Memory technology in an IPR proceeding. The PTAB institution decision found a reasonable likelihood of obviousness based on prior art, moving the case into trial preparation.
Micron Technology, Inc. et al. v.YANGTZE MEMORY TECHNOLOGIES COMPANY, LTD.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
HARMAN INTERNATIONAL INDUSTRIES, INC. v.ST CasesTech, LLC et al.
Harman and CasesTech settled their IPR dispute, filing joint motions that led the Board to terminate the proceeding before trial. The settlement agreement was deemed confidential, and counsel withdrawals were approved.
