Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
The PTAB denied the IPR petition against claims 1-4 of U.S. Patent No. 9,457,541, finding that the combination of prior art references did not render the copper foil obvious.

Apple Inc. v.RJ Technology LLC
Apple Inc. filed a Petition challenging the validity of RJ Technology LLC's patent '641, asserting that claims 1-18 are anticipated or obvious over prior art references like Uemura and Abe. The petitioner argues that the claimed battery characteristics are fully disclosed or rendered obvious by combining these existing technologies.
Apple Inc. v.RJ Technology LLC
The PTAB issued a Final Written Decision finding multiple claims of the patent unpatentable as obvious in view of prior art. The Board focused heavily on claim construction, specifically defining 'charge cut-off voltage' based on practical full-cell operation rather than just applied charging potential. Claims 2–4 and 6–18 were found invalid under 103.
