Short Summary
The Board instituted the IPR petition against Patent No. 10589225, finding a reasonable likelihood of prevailing on multiple grounds. The institution decision addressed complex issues regarding real party in interest and written description support for genus claims related to flue gas treatment.
Detailed Summary
The Petitioner successfully convinced the Patent Trial and Appeal Board (PTAB) that there was a reasonable likelihood of prevailing on several asserted grounds against Patent No. 10589225, leading to institution. The petition challenged claims using anticipation by Olson-235 (under § 102) and obviousness over Sjostrom/Eckberg and Sjostrom/Olson-646 (under § 103). Crucially, the Board rejected the Patent Owner's argument that the petition was time-barred due to lack of privity in related district court litigation. Furthermore, the Board found insufficient evidence regarding written description support for the genus claims based on the Provisional Application.
