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.

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.
