Decision Denying Petitioner’s Requests For Rehearing, General Plastic Industrial Co., Ltd. v. Canon Kabushiki Kaisha, Nos. Case IPR2016-01357, 01358, 01359, 01360, 01361 (P.T.A.B. September 6, 2017) (expanded panel)
Last year, the Patent Trial and Appeal Board (“PTAB”) set out seven factors that could be considered in determining whether to grant or deny a subsequent petition for inter partes review (“IPR”) after denial of a previous petition—a so-called “follow-on” petition. Moving forward, IPR participants should pay close attention to how the PTAB applies these factors and whether it adds more.
In September 2015, General Plastic filed two IPR petitions challenging claims in Canon patents. The PTAB denied institution on the merits in March 2016 and subsequently denied General Plastic’s requests for rehearing. Then, in July 2016, General Plastic filed five subsequent petitions, again challenging claims of the same Canon patents. Again, the PTAB denied those petitions.
