No One Likes a Sore Winner: IPR Prevailing Party Can’t Appeal

Reaffirming precedent, the US Court of Appeals for the Federal Circuit reiterated the rule that the prevailing party in an inter partes review (IPR) cannot appeal a Patent Trial & Appeal Board decision. Termax Co. v. Illinois Tool Works, Inc., Case Nos. 23-1252; -1254 (Fed. Cir. Mar. 8, 2023) (Dyk, Reyna, Chen, JJ.)

Illinois Tool Works (ITW) asserted that Termax had infringed a patent directed to an automobile fastener. Termax challenged the asserted patent by filing a petition for IPR. The petition was granted, and ultimately the Board agreed with Termax that all the challenged claims of ITW were unpatentable. Both parties appealed.

ITW moved to voluntarily dismiss its own appeal and to dismiss Termax’s cross-appeal. Termax opposed, arguing that the Board erred in its construction of certain claim limitations that have also been incorporated into a new ITW patent.

The Federal Circuit dismissed both appeals. Citing what it called a “familiar rule,” the Court stated that the winner in a lower court or other tribunal cannot ordinarily seek relief in the appellate court. The Court was not persuaded by Termax’s argument that the Board erred in its construction of certain claim limitations, noting that Termax sought to appeal the constructions in the hopes that a Federal Circuit decision in its favor would “collaterally estop Illinois Tool Works from asserting those newly issued claims.” However, the Court refused to hear the appeal prematurely, stating that if ITW asserts the claims of its new patent against Termax in the future, Termax can address the issue at that time.

Practice Note: While an IPR can be a powerful tool for accused infringers, it is not without future risks.

Prior Art Coherency and Cache Incoherency: “Known-Technique” Rationale for Motivation to Combine

By Jake B. Vallen on Mar 23, 2023

The US Court of Appeals for the Federal Circuit, addressing the issue of whether certain factual and legal conclusions relating to obviousness were supported by substantial evidence, held that the Patent Trial & Appeal Board improperly rejected evidence of “known-technique” rationale to provide a motivation to combine. Intel Corp. v. PACT XPP Schweiz AG, Case No. 22-1037 (Fed. Cir. Mar. 13, 2023) (Newman, Prost, Hughes, JJ.)

PACT owns a patent that “relates to multiprocessor systems and how processors in those systems access data.” The claimed multiprocessor system addressed cache incoherency, a problem associated with the use of multiple cache memories to store data, particularly local copies of the same data stored on multiple processors. Cache incoherency (i.e., inconsistencies among different cache processors) “may arise if one processor changes its local copy of the data and that change isn’t propagated to the other copies of that data.”

Intel petitioned for inter partes review of claims 4 and 5 of the patent, relying on two prior art references, Kabemoto and Bauman. Kabemoto and Bauman both address the problem of cache incoherency. As the Federal Circuit explained, Kabemoto maintains cache coherency “by ‘snooping’ along a shared ‘bus,’” while Bauman “us[es] a global, segmented secondary cache.”

The Board upheld the patentability of the challenged claims, concluding that “Intel failed to prove the obviousness of each limitation of [independent] claim 4,” from which claim 5 depended. Intel had contended that a person of ordinary skill in the art would combine Kabemoto and Bauman to teach all limitations in claim 4 by “replac[ing] Kabemoto’s secondary caches” with “Bauman’s segmented global [secondary cache],” which is a separate cache. PACT did not dispute that the combination of Kabemoto and Bauman taught each limitation of claim 4 but argued that Intel failed to demonstrate a motivation to combine Kabemoto and Bauman.

The Board nevertheless found that Intel failed to demonstrate that the prior art disclosed the segment-to-segment limitation and concluded that Intel failed to show that a person of ordinary skill in the art would have been motivated to combine the teachings of Kabemoto and Bauman. Intel appealed.

The Federal Circuit first addressed Intel’s contention “that substantial evidence d[id] not support the Board’s determination that the prior art fails to disclose the segment-by-segment limitation” of claim 4. The Court found that “Bauman’s Figure 6 teaches—if not plainly illustrates—the segment-to-segment limitation of the claims interconnect system” and reversed the Board’s contrary conclusion.

Next, the Federal Circuit addressed Intel’s contention that the Board’s determination that there was no motivation to combine Kabemoto and Bauman was not supported by substantial evidence. On this issue, the Court reasoned that under KSR, it was “enough for Intel to show that there was a known problem of cache incoherency in the art, that Bauman’s secondary cache helped address that issue, and that combining the teachings of Kabemoto and Bauman wasn’t beyond the skill of an ordinary artisan.” As the Court put it, “[n]othing more is required to show a motivation to combine under KSR.”

Actual or Potential Consumers in Related Goods Context Doesn’t Require PURE Overlap

By Benjamin Ediger, Ph.D. on Mar 23, 2023
Posted In Trademarks

The US Court of Appeals for the Federal Circuit reminded us that, in the context of related goods, the likelihood of confusion analysis does not require that actual or potential consumers of the goods be the same, but only that there be sufficient overlap. In re Oxiteno S.A. Industria e Comercio, Case No. 22-1213 (Fed. Cir. Mar. 9, 2023) (Dyk, Bryson, Prost, JJ.)

Oxiteno filed an intent-to-use trademark application for OXIPURITY, with its goods and services statement ultimately amended to include dozens of chemical products “for use in the pharmaceutical, veterinary, flavor and fragrance, and cosmetic fields.” The application was refused on likelihood of confusion grounds in view of FMC Corporation’s registered OXYPURE mark, largely because the hydrogen peroxide products covered by the OXYPURE registration moved through the same channels of trade as products recited in the Oxiteno application.

Oxiteno appealed the refusal to the Trademark Trial & Appeal Board. The Board analyzed likelihood of confusion using the DuPont factors and found the first four factors most relevant:

Factor 1: The similarity of OXIPURITY and OXYPURE. The Board concluded (as had the Examiner) that the two marks were “similar in sound, meaning and commercial impression,” and found that this factor strongly favored a likelihood of confusion.

Factor 2: The similarity of the covered goods. The Board agreed with the Examiner that the respective goods, while not the same, were sufficiently related to favor a likelihood of confusion finding.

Factor 3: The similarity of channels of trade. The Board reviewed the third-party websites that the Examiner considered particularly dispositive. The websites sold hydrogen peroxide goods covered by the OXYPURE mark and the chemicals Oxiteno intended to sell under the OXIPURITY mark. The Board concluded that the same sources manufactured FMC’s established products and Oxiteno’s intent-too-use products, and directly sold these products to largely overlapping industries.

Factor 4: “[t]he conditions under which and buyers to whom sales are made.” Of the four most relevant factors in this case, this was the only factor that the Board found to favor registration. The Board concluded that the consumers of the established and intent-to-use products would be sophisticated and not act on impulse.

Despite the potential consumers’ presumed sophistication, the Board found that factors 1 through 3 “rendered confusion likely” and thus affirmed the Examiner’s refusal. Oxiteno appealed.

Oxiteno argued that likelihood of confusion could not be found when the actual or potential consumers of the respective products covered by two marks were not the same, as with the relevant products here.

The Federal Circuit affirmed the Board, noting statements made by a company selling Oxiteno’s products that explained why almost every business is a potential purchaser of FMC’s OXYPURE hydrogen peroxide products. The Court also noted that FMC’s brochures stated that it sold its hydrogen peroxide products under OXYPURE and other brand names to the same key industries to which Oxiteno sold its products. The Court, therefore, concluded that substantial evidence supported that at least some [...]

Not Today, HAL: Copyright Still Requires Human Input

By Anisa Noorassa on Mar 23, 2023

The US Copyright Office (USCO) issued a policy statement on March 16, 2023, clarifying its position on the use of artificial intelligence (AI) in copyrighted materials. This statement came in the wake of the USCO’s recent decision to revoke partial copyright protection over AI-generated images in a graphic novel.

The USCO had previously issued copyright registration to Kris Kashtanova for a graphic novel. Upon learning that the images had been generated using Midjourney, an AI that produces images based on text prompts, the USCO revoked copyright protection over the images consisting of mixed text and images. Zarya of the Dawn, Registration No. VAu001480196 (USCO, Feb. 21, 2023) (Kasunic, Asso. Register of Copr.)

The USCO explained that the images lacked the requisite “minimum creative spark” required to make the images copyrightable. The USCO further emphasized that a human author with ultimate creative control is necessary for copyright protection and that providing an AI with word prompts is insufficient to qualify. Therefore, the copyright registration for the images in Kashtanova’s novel was revoked. However, because the work consisted of images and text and the text was all written by Kashtanova, that aspect of the work did satisfy the requirements for copyright protection and retained its registration. The USCO did allow that if Kashtanova could exhibit “substantive edits” to an AI-generated image, those edits could prove human authorship and therefore qualify the image for copyright protection.

In its March 16 policy statement, the USCO reiterated that non-humans are firmly excluded from authorship and, therefore, solely AI generated works are ineligible for copyright registration. Applicants should not list AIs as authors, but authors do have a duty to disclose the use of AI in their work and provide an explanation of their own human contribution compared to that of the AI. The USCO explained that the use of AI tools does not necessarily exclude a work from copyright registration. The salient issue in such cases would be the extent of creative control that the human author had over the work and its creative expression. As long as the human-made modifications to the AI-generated work meet the “minimum creative spark” requirement, such works could be subject to copyright protection.

Show Your Work: PTO Director’s Procedure for Issuing Instructions Is Reviewable

By Rodney Swartz, PhD on Mar 23, 2023

The US Court of Appeals for the Federal Circuit affirmed the district court’s finding under the Administrative Procedure Act (APA) that the substance of the US Patent & Trademark Office (PTO) Director’s instructions is unreviewable but reversed the finding that the cloak of unreviewability extended to the procedure used in issuing the instructions. Apple v. Vidal, Case No. 22-1249 (Fed. Cir. Mar. 13, 2023) (Lourie, Taranto, Stoll, JJ.)

The creation of the inter partes review (IPR) program opened new avenues for reviewing the validity of patents following issuance. Since the program’s inception, Congress has recognized that there is a possibility of parallel proceedings at the Patent Trial & Appeal Board and in the district court, that such proceedings could result in conflicting decisions and reduced efficiency in the system. However, Congress left it to the discretion of the two branches to work out such situations among themselves.

As one lever to overcome these issues, Congress provided the Director with unreviewable discretion in deciding whether to institute an IPR. Recently, the Director attempted to leverage this power to increase efficiencies and reduce gamesmanship by instructing the Board on what to consider when instituting an IPR.

Apple and four other companies challenged these instructions in the district court. Apple argued that the Director’s instructions violated the APA by being contrary to the IPR provisions, arbitrary and capricious, and issued without the notice-and-comment rulemaking required under the APA.

Following a motion to dismiss, the district court concluded that Apple’s challenges were directed at the Director’s actions, making them unreviewable by the court. Apple appealed.

On appeal, the Federal Circuit considered all three of Apple’s APA challenges to the instructions, along with whether Apple had standing to bring the suit. The Court agreed with the district court that the question of whether an instruction violates the APA by being contrary to the IPR provisions or by being arbitrary and capricious is directed to the substance of the Director’s action and is not reviewable: “§ 314(a) invests the Director with discretion on the question whether to institute review . . . : The determination by the Director whether to institute an inter partes review . . . shall be final and nonappealable.” As the Federal Circuit noted, this conclusion rests on the well-supported need for the PTO Director to give guidance to delegatees on how to make institution determinations.

The Federal Circuit disagreed that the announcement procedure the Director used for issuing the instructions to the Board was unreviewable, however. As the Court noted, the procedure employed by an agency to announce guidelines is “quite apart” from the substance of those guidelines. Given this distinction, the Court concluded that the procedure the Director used to announce the instructions was reviewable: “The government here has not shown that anything in § 314(d) or elsewhere in the IPR statute supplies clear and convincing evidence that there was to be no judicial review of the choice of announcement procedure, a matter for which generally applicable standards exist.”
