Objective Indicia of Nonobviousness for Design Patents: Same Nexus Requirement as Utility Patents

The US Court of Appeals for the Federal Circuit reversed two decisions by the Patent Trial & Appeal Board (Board), finding that a soup company and soup dispenser manufacturing company failed to prove the unpatentability of two design patents covering can dispensers. The Court also concluded that the analysis for objective indicia of nonobviousness for utility patents also applies to design patents. Campbell Soup Co. v. Gamon Plus, Inc., Case Nos. 20-2344, 21-1019 (Fed. Cir. Aug. 19, 2021) (Moore, J.)

Gamon Plus owns two design patents directed to “the ornamental design for a gravity feed dispenser display,” or a can dispenser. Gamon’s commercialized embodiment is called the iQ Maximizer gravity feed dispenser. For nearly a decade, Gamon sold tens of millions of dollars’ worth of its iQ Maximizer to Campbell Soup. Campbell attributed increased soup sales in part to the iQ Maximizer in its 10-K Securities and Exchange Commission reports (an industry publication) and in an internal marketing study. Campbell later began purchasing similar gravity feed dispensers from Trinity Manufacturing.

Gamon sued Campbell and Trinity for design patent infringement. Campbell and Trinity then petitioned for inter partes review (IPR) of Gamon’s patents. In its final written decisions, the Board found that Campbell and Trinity failed to prove unpatentability because the prior art was not similar enough to the claimed designs to constitute a proper primary reference. Trinity (Campbell) appealed.

In that appeal, the Federal Circuit disagreed, vacated and remanded. On remand, the Board again held that Campbell and Trinity failed to prove unpatentability, finding that the claimed designs would not have been obvious over the prior art. The Board reasoned that although the prior art alone had the same overall visual appearance as the claimed designs, there existed objective indicia of nonobviousness, including Gamon’s commercial success in selling iQ Maximizers to Campbell, Campbell’s praise of—and commercial success in—using the iQ Maximizer and Trinity’s copying of the iQ Maximizer. The Board presumed a nexus between those objective indicia evidences and the claimed designs because it found the iQ Maximizer to be coextensive with the claims, meaning that the product was essentially the disclosed invention with unclaimed features being insignificant. The Board also found that Gamon established such a nexus regardless of the presumption. Campbell and Trinity again appealed.

Again the Federal Circuit reversed, concluding that the claimed designs would have been obvious over the prior art. In doing so, the Court confirmed the Board’s finding that the prior art and the claimed designs shared the same overall visual appearance (which Gamon did not challenge) but found that the Board’s presumption of nexus and finding of a nexus-in-fact between the claimed designs and the evidence of commercial success and praise were not supported by substantial evidence. As for the presumption, the Court considered whether the iQ Maximizer was coextensive with the claimed invention. Nexus is presumed if the objective indicia evidence is tied to a specific product that is “coextensive” with the claimed invention. The Board recognized that the claimed portions of [...]

Even Judges Have a Boss: PTAB Must Sufficiently Articulate its Obviousness Reasoning

Addressing the sufficiency of the Patent Trial & Appeal Board’s (PTAB) justification of its inter partes review (IPR) determination, the US Court of Appeals for the Federal Circuit reversed the PTAB’s obviousness determinations, concluding that the PTAB’s findings regarding motivation to combine were not supported by substantial evidence. Chemours Company FC, LLC v. Daikin Industries, Ltd., Daikin America, Inc., Case No. 20-1289, -1290 (Fed. Cir., July 21, 2021) (Reyna, J.) (Dyk, J., concurring in part and dissenting in part).

Chemours, owner of the challenged patents, appealed the PTAB’s final written decisions in two IPRs initiated by Daikin. The challenged claims relate to a unique polymer for insulating communication cables formed by pulling wires through melted polymer to coat and insulate the wires, a process known as “extrusion.” The challenged claims of the patents recite that the polymer has a specific melt flow range of about 30+/- g/10 mins. The polymer’s melt flow range correlates with how fast the melted polymer can flow under pressure during extrusion. A higher melt flow rate means a faster coating of the polymer onto a wire. During the IPRs, the PTAB found all challenged claims unpatentable as obvious.

The Federal Circuit reviews the PTAB’s legal determinations de novo and its factual findings for substantial evidence, which “requires more than a ‘mere scintilla’ and must be enough such that a reasonable mind could accept the evidence as adequate to support the conclusion.” Obviousness is a question of law necessarily made on underlying findings of fact, and in making factual findings, the PTAB “must have both an adequate evidentiary basis for its findings and articulate a satisfactory explanation for those findings.”

In this instance, the Federal Circuit found that the PTAB’s obviousness findings were not supported by substantial evidence. According to the Court, while the PTAB may rely on prior art other than the references being applied or combined to inform itself of the state of the art at the time of the invention, the scope of the relevant prior art encompasses only that which is “’reasonably pertinent to the particular problem with which the inventor was involved.”’ Here, the Court explained that the only prior art reference relied on was not appropriate because it expressly taught away from the claimed invention and relied on teachings from other references that were not concerned with the particular problems the prior art sought to solve. As the Court noted, the PTAB “did not adequately grapple with why a skilled artisan would find it obvious to increase [the reference’s] melt flow rate to [the] claimed range while retaining its critical ‘very narrow molecular-weight distribution.’” To support its obviousness conclusion, the PTAB needed “competent proof showing a skilled artisan would have been motivated to, and reasonably expected to be able to, increase the melt flow rate of [the reference’s] polymer to the claimed range when all known methods for doing so would go against [the reference’s] invention by broadening molecular weight distribution.” By failing to provide its reasoning, the PTAB relied [...]
