The PTAB recently exercised its discretion under 35 U.S.C. ' 314 to deny institution of inter partes review for inefficient use of the PTAB's time and resources notwithstanding that the petitioner met the threshold for institution as to one challenged claim. Salem Fabrication Techs. Grp., Inc., v. Uniglass Eng'g Oy, No. IPR2022-01517, Paper 9 at 25 (P.T.A.B. Mar. 22, 2023)("Decision"). The PTAB's Decision highlights that under 35 U.S.C. ' 314(a), whereby the PTAB may not institute an IPR "unless . . . there is a reasonable likelihood that a petitioner will prevail with respect to at least 1 of the claims challenged," institution remains discretionary even where a petitioner is reasonably likely to prevail on one challenged claim. Id. at 23-24 (citing SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1356 (2018) and Harmonica Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016)).
Salem Fabrication Technologies Group, Inc. ("Petitioner") petitioned for IPR of Uniglass Engineering Oy's patent relating to a glass tempering furnace, challenging all fifteen of the patent's claims multiple times as obvious under 35 U.S.C.

The PTAB found that six grounds suffered from hindsight bias because Petitioner did not establish motivation for a person of ordinary skill in the art to combine or modify the prior art. Id. at 14. The PTAB noted that a petitioner must "explain[] . . . how or why the references would be combined to produce the claimed invention" and that Petitioner provided "no reason whatsoever." Id. (quoting Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d 1342, 1368 (Fed. Cir. 2012)). Simply asserting that references are from the same field as the claimed invention or that they would have been considered by the POSITA is insufficient to show motivation. Id. at 15-16.
The PTAB found that Petitioner's arguments and evidence of obviousness met...
