JIANGSU FAVORED NANOTECHNOLOGY CO., LTD. v.P2i Ltd.
JIANGSU FAVORED NANOTECHNOLOGY CO., LTD. successfully petitioned to overturn a discretionary denial of IPR for P2i Ltd.'s patent (11041087). The Board found that the prior art was sufficiently evaluated during prosecution, leading to the institution of the case on § 103 grounds.
Air Products and Chemicals, Inc. v.EVONIK OPERATIONS GMBH et al.
Air Products challenges EVONIK's membrane technology patent (10471380), arguing the claims are obvious over prior art references Ungerank and Scholz. The petitioner asserts that skilled artisans would have been motivated to combine these teachings to achieve the claimed features in gas separation.
Air Products and Chemicals, Inc. v.EVONIK OPERATIONS GMBH et al.
The IPR petition against EVONIK's gas separation membrane technology failed as the Petitioner could not establish unpatentability. The Board found that the combination of cited prior art references lacked a sufficient motivation to combine, upholding the patent's validity.
Air Products and Chemicals, Inc. v.EVONIK OPERATIONS GMBH et al.
Air Products successfully convinced the PTAB to institute an IPR on 23 claims of EVONIK's patent, finding a reasonable likelihood that at least Claim 1 would be obvious over Ungerank and Scholz. The Board rejected arguments that the prior art taught away from the claimed invention.
