Vidal Vacates Board’s Denial of IPR Institution on Auto Part Patent

U.S. Patent and Trademark Workplace (USPTO) Director Kathi Vidal vacated and remanded a choice of the Patent Trial and Enchantment Board (PTAB) on Friday that had denied establishment of an inter partes assessment (IPR) requested by auto elements producer, Mahle Behr Charleston, Inc.

U.S. Patent No. RE47,494 E is owned by inventor Frank Amidio Catalano and covers “a tool to forestall corrosion [in motor vehicle radiators] brought on by electrolysis.” Mahle Behr requested IPR of the patent, arguing {that a} prior artwork reference known as Godefroy anticipates and renders apparent sure claims, whereas the patent proprietor countered that the prior artwork particularly fails “to show ‘a sacrificial anode [that] is put in inside ten inches of a scorching liquid inlet of the radiator as recited in claims 12, 25, or 37…” and thus “It might not have been apparent to switch the prior artwork radiators, gadgets and strategies to reach on the combos embodied by [those] claims.”

The Board ultimately agreed with Catalano that there was not an inexpensive probability that the petitioner would prevail with respect to at the very least one of many challenged claims. In its determination, the Board relied on Hockerson-Halberstadt, Inc. v. Avia Group International, Inc., 222 F.3d 951 (Fed. Cir. 2000), which mentioned partially that “[p]atent drawings don’t outline the exact proportions of the weather and is probably not relied on to indicate specific sizes if the specification is totally silent on the difficulty.” Mahle Behr’s skilled admitted that the prior artwork didn’t present actual dimensions with Determine 1, so the Board concluded that it couldn’t be relied on “to show or counsel the 10-inch limitation of the challenged claims”. However Mahle Behr argued that the PTAB misapplied Hockerson and “disregarded the prior artwork’s facial educating of the dimensional vary.” Mahle Behr petitioned for Director Review in November 2023.

In her determination granting Director Assessment, Vidal agreed that the Board failed to contemplate Mahle Behr’s arguments that the prior artwork was “clear on its face” as to the exact proportions and famous that, in keeping with Cummins-Allison Corp. v. SBM Co., 484 F. App’x 499, 507 (Fed. Cir. 2012), the place “an individual of talent within the artwork might derive the claimed dimensions from the patent’s disclosure, there is no such thing as a further requirement that the specification should explicitly disclose the exact proportions or specific sizes.”

On remand, Vidal ordered the Board to find out “whether or not Petitioner has demonstrated that Determine 1 of Godefroy ‘is evident on its face’ or would have moderately recommended the position of Godefroy’s sacrificial anode ‘inside 10 inches’ of the new liquid inlet.” Particularly, Vidal mentioned the Board ought to contemplate whether or not the skilled testimony offers adequate “technical element, clarification, or statements supporting why the skilled determines that the function in query was required or would have been apparent based mostly on the prior artwork disclosure.”
