Runergy Alabama Inc et al. v.Trina Solar Co. Ltd.
The Petitioner successfully demonstrated that all 17 challenged claims are unpatentable under 35 U.S.C. § 103(a). The Board found specific combinations of prior art, notably Chang and Jin, rendered the claimed solar cell structures obvious.
Runergy Alabama Inc et al. v.Trina Solar Co. Ltd.
The PTAB issued a Final Written Decision finding all 11 challenged claims unpatentable under 35 U.S.C. § 103(a). The Board found that the Petitioner successfully demonstrated obviousness over combinations of prior art, specifically involving Chang and Jin for isolation regions in solar cells.
Mundra Solar PV Ltd. et al. v.Trina Solar Co. Ltd.
The PTAB issued a Final Written Decision finding that all 11 challenged claims of the solar cell patent were obvious over prior art references. The Board credited the petitioner's evidence, concluding that an ordinary artisan would have combined Chang and Jin to achieve the claimed isolation features with reasonable success.
Mundra Solar PV Ltd. et al. v.Trina Solar Co. Ltd.
The PTAB found all 17 challenged claims unpatentable under 35 U.S.C. § 103, concluding that the combination of prior art references was sufficient to teach the claimed solar cell structure. This decision validates the Petitioner's arguments regarding obviousness in photovoltaic technology.
Canadian Solar (USA) Inc. et al. v.Trina Solar Co. Ltd.
The PTAB found all 11 challenged claims of the solar cell patent unpatentable based on obviousness (35 U.S.C. § 103). The Board determined that combining prior art references, particularly Chang and Jin, would motivate an ordinary skilled artisan to make the claimed structure with a reasonable expectation of success.
Canadian Solar (USA) Inc. et al. v.Trina Solar Co. Ltd.
The PTAB found all 17 challenged claims unpatentable under 35 U.S.C. § 103(a) for the solar cell technology. The Board concluded that Petitioner successfully demonstrated obviousness over Chang in view of Jin, or other combinations.
Runergy Alabama Inc et al. v.Trina Solar Co. Ltd.
The PTAB institution decision granted the petitioner a reasonable likelihood of prevailing on all challenged claims related to solar cell technology. The grounds for obviousness centered on combining prior art references like Jin and Feldmann to achieve predictable improvements in TOPCon structure efficiency.
Runergy Alabama Inc et al. v.Trina Solar Co. Ltd.
The PTAB has issued an Institution Decision for IPR2025-00007, finding that the Petitioner demonstrated a reasonable likelihood of prevailing on at least one challenged claim. The case involves obviousness challenges (103) against Trina Solar's solar cell patent using combinations of prior art from Jin, Feldmann, Chang, Seo, and Watabe.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
Zhuhai CosMX Battery Co., Ltd.'s IPR challenge against Ningde Amperex Technology Ltd. was denied by the PTAB. The Board found insufficient evidence to overcome anticipation and obviousness grounds related to lithium-ion battery separator materials.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
Zhuhai CosMX Battery Co. successfully petitioned the PTAB, leading to the institution of IPR proceedings against Ningde Amperex Technology Ltd.'s lithium-ion battery patent (11,923,498). The Board found a reasonable likelihood of success on obviousness grounds over multiple prior art references.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
Zhuhai CosMX Battery Co., Ltd. successfully petitioned to institute IPR proceedings against Ningde Amperex Technology Ltd.'s patent (11769910). The Board found sufficient evidence that the claims are unpatentable under 35 U.S.C. § 103 over various prior art references, including Zeng and Zhou. This ruling advances a critical battery technology dispute into trial.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
Zhuhai CosMX Battery Co., Ltd. successfully demonstrated a reasonable likelihood of success in its IPR against Ningde Amperex Technology Ltd.'s patent, focusing on obviousness under 35 U.S.C. § 103. The Board found that the petitioner adequately showed Murakami discloses key features and that combinations with Beard and Akiike were motivated and predictable.
ITM Isotope Technologies Munich SE v.The Johns Hopkins University et al.
ITM Isotope Technologies Munich SE challenged The Johns Hopkins University's claims regarding FAP-α targeting moieties based on obviousness and patentability issues (103/112). The Board instituted the PGR, finding that the claims face significant challenges related to enablement and indefiniteness.
ITM Isotope Technologies Munich SE v.The Johns Hopkins University et al.
ITM Isotope Technologies and Johns Hopkins University settled their dispute over U.S. Patent 12,115,233, leading the PTAB to terminate the post‑grant review before institution.
Cargill, Incorporated v.Bunge Loders Croklaan USA, LLC
Cargill's request for rehearing was denied after the PTAB previously denied institution of IPR against Bunge Loders Croklaan USA regarding a vegetable fat composition patent. The Board found that Cargill’s arguments relied on hindsight bias, specifically in selecting prior art examples to meet claimed triglyceride ranges.
Cargill, Incorporated v.Bunge Loders Croklaan USA, LLC
The PTAB denied institution of an IPR challenge brought by Cargill against Bunge Loders Croklaan regarding vegetable fat composition claims. The Board found that the petitioner failed to overcome obviousness grounds, specifically rejecting arguments based on hindsight bias when converting prior art data.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
The PTAB institution decision found that the challenged claims related to lithium-ion battery electrolytes were obvious over various combinations of prior art references. The Petitioner successfully argued that a Person of Ordinary Skill in the Art would be motivated to combine elements from Zeng, Sunose, and Matsuoka to achieve improved performance. This ruling advances the scope of obviousness findings in advanced energy storage technology.
Zhuhai CosMX Battery Co., Ltd. v.Ningde Amperex Technology Ltd.
The PTAB granted institution for the petitioner's IPR challenge against U.S. Patent 12,015,118 B2, covering lithium-ion battery electrode structures. The Board found reasonable likelihood of prevailing on both anticipation (Ishigaki) and obviousness grounds over multiple prior art references.
Syngenta Crop Protection AG v.Inflexion Point Technologies, LLC
Syngenta Crop Protection AG's petition to invalidate Inflexion Point Technologies' patent was denied by the PTAB. The Board found insufficient evidence of anticipation or obviousness across multiple grounds, rejecting all challenges including enablement.
