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.
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 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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
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.
Canadian Solar Inc. et al. v.Maxeon Solar Pte. Ltd.
The PTAB issued a Final Written Decision rejecting all challenged claims (10-16 and 19) in this IPR regarding solar cell fabrication techniques. The Board found that the Petitioner failed to provide sufficient motivation to combine prior art references, particularly concerning optimal dopant concentrations.
Canadian Solar Inc et al. v.Maxeon Solar Pte. Ltd.
The PTAB issued a Final Written Decision finding that claims 9, 10, and 11 of patent 8222516 were obvious over the combination of Froitzheim and Gan. The Board rejected the challenge to claim 12 due to specific limitations in the prior art references.
Canadian Solar Inc. et al. v.Maxeon Solar Pte. Ltd.
The PTAB issued a Final Written Decision finding claims 9-20 of the patent unpatentable based on obviousness (35 U.S.C. § 103). The Board found that substituting known elements, such as polysilicon emitters for diffused emitters, was predictable and rendered the claimed technology obvious over combinations of prior art references like Gan and Froitzheim.
Canadian Solar Inc. et al. v.Maxeon Solar Pte. Ltd.
The PTAB issued a Final Written Decision denying the Petitioner's arguments that claims 10-16 and 19 were unpatentable. The Board found insufficient motivation in the prior art to combine references, particularly regarding optimal dopant concentrations for solar cell fabrication techniques.
Hanwha Solutions Corporation v.Maxeon Solar Pte. Ltd. et al.
The PTAB issued a final written decision denying Petitioner's challenge to claims 10-20 of Maxeon Solar Pte. Ltd.'s patent. The Board construed the key term 'metal impurities' as 'unintentional foreign metals,' rejecting arguments that intentional dopants qualified. Ultimately, the Petitioner failed to demonstrate unpatentability by a preponderance of the evidence.
Hanwha Solutions Corporation v.Maxeon Solar Pte. Ltd.
The PTAB issued a Final Written Decision finding all 20 challenged claims unpatentable based on obviousness (103). The Petitioner successfully demonstrated that various combinations of prior art—including Froitzheim, Gan, Smith, and Li—would render the Maxeon patent obvious to a person skilled in the art.
Hanwha Solutions Corporation v.Maxeon Solar Pte. Ltd.
The PTAB issued a Final Written Decision finding that claims 1-11 are unpatentable over combinations of prior art references (Froitzheim, Gan, Sheats). Claim 12 was not shown to be unpatentable. The Board found the Petitioner met its burden regarding reasonable expectation of success for several claims.
R.J. Reynolds Vapor Company et al. v.Healthier Choices Management Corp.
The PTAB issued a Final Written Decision finding all four challenged claims of U.S. Patent No. 9538788 unpatentable under 35 U.S.C. § 103.
