Keep Calm and Party On: New Issue Prohibition Doesn’t Apply to Motions to Amend

by Amol Parikh | Jan 25, 2024 | Patents

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board obviousness determination, explaining that inter partes review (IPR) statutory provisions that prohibit an otherwise time-barred party from introducing new issues into the proceeding do not apply to motions to amend. CyWee Group Ltd. v. ZTE (USA), Inc. et al., Case No. 21-1855 (Fed. Cir. Jan. 18, 2024) (Prost, Hughes, Stoll JJ.)

CyWee owns a patent directed to a “three-dimensional (3D) pointing device capable of accurately outputting a deviation including yaw, pitch and roll angles in a 3D reference frame and preferably in an absolute manner.” ZTE filed a petition for IPR of the patent asserting that certain claims were unpatentable. The Board instituted the IPR. LG later filed an IPR petition challenging the patent and moved to join ZTE’s ongoing IPR, stating that it would “act as a passive ‘understudy’ and [would] not assume an active role unless [ZTE] ceases to participate in the instituted IPR.”

While LG’s motion was pending, CyWee moved to amend its patent claims, contingent on cancellation of the original claims. ZTE opposed the motion to amend. The Board gave preliminary guidance that the proposed claims lacked written description support and introduced new matter, and also that one of the proposed claims was invalid over the asserted prior art.

The Board granted LG’s motion to join ZTE’s IPR proceeding but placed restrictions on LG’s participation that required LG to consolidate filings with ZTE, rely on ZTE to take and defend depositions, refrain from requesting or reserving additional deposition or oral hearing time, and agree to other procedural concessions to minimize delay to the IPR proceeding.

After LG’s joinder, CyWee filed a revised motion to amend. ZTE indicated that it did not oppose the motion. LG, arguing that ZTE was no longer actively participating in the IPR, moved for leave to oppose CyWee’s motion to amend. Ultimately, the Board permitted LG to present argument and evidence independent from ZTE. LG filed an opposition arguing that CyWee’s proposed revised claims were obvious over Withanawasam, Bachmann and Bachmann2. Notably, ZTE had not cited Withanawasam in its opposition to CyWee’s initial motion to amend.

After the Board issued its final decision finding that the proposed revised claims were obvious over Withanawasam, Bachmann and Bachmann2, CyWee appealed.

CyWee argued that the Board erred by allowing LG to oppose CyWee’s motion to amend in a manner that violated the terms of LG’s joinder and by allowing LG to raise Withanawasam in opposition to the motion to amend. The Federal Circuit rejected both arguments. The Court explained that the Board concluded that although ZTE still participated in the IPR, the proceeding “no longer appear[ed] to be meaningfully adversarial” as to the revised motion to amend. The Court found no error in the Board’s conclusion that ZTE was no longer an active participant in the IPR proceeding, and thus there was no violation of the joinder terms.

The Federal Circuit also concluded that the Board did not err [...]

Strings Attached: No Amendment for Trademark Application in Inter Partes Opposition Proceeding

by Joshua Revilla | Feb 2, 2023 | Trademarks

The Trademark Trial & Appeal Board (Board) designated as precedential a decision denying a motion to amend and granting partial summary judgment based on a mistaken identification that did not match the goods sold using the trademark. Fender Musical Instruments Corporation v. Win-D-Fender, LLC, Opp. No. 91272326 (TTAB Sept. 22, 2022) (designated precedential Jan. 12, 2023) (Wolfson, Heasley, Cogins, ATJs) (By the Board).

Win-D-Fender applied for a trademark to register the mark EN-D-FENDER for “musical instruments.” Fender opposed this registration on grounds of nonuse, likelihood of confusion and dilution by blurring and filed a motion for summary judgment on the ground of nonuse. Win-D-Fender then filed a motion to amend the identification of goods in its application from “musical instruments” to “musical instrument accessories, namely, an ambient wind foot joint guard for flute family instruments.”

The Board first considered Win-D-Fender’s motion to amend. Under the relevant trademark rules, an application that is subject to an inter partes proceeding may only be amended if the other party consents (Fender did not) and the Board gives approval, or if the Board grants a motion to amend.

Win-D-Fender filed its application via the Trademark Electronic Application System (TEAS). In a TEAS application, only the goods listed in the proper field can be considered for the identification of goods and broadening the scope of the identification is not permitted. In Win-D-Fender’s application, the only goods listed in the “Identification” field were “musical instruments.” Win-D-Fender argued that its application included a miscellaneous statement reading, “For Musical Instrument Accessories namely a wind guard mounted to a flute.” The Board determined, however, that the description was not in the proper field and therefore was not considered in the identified goods. The Board explained that the TEAS Plus instructions warn applicants to not use the TEAS Plus “Identification” field if it does not contain an accurate listing of the goods and services and to instead use the TEAS Standard filing option. The Board noted that although the identification of “musical instruments” may have been a mistake, it is settled that an established identification cannot later be expanded. The Board concluded that Win-D-Fender was limited to amendments that would narrow or clarify the type of “musical instruments.”

Win-D-Fender also argued that musical instrument accessories would fall under the general umbrella of musical instruments. The Board stated that while musical instruments may use accessories, the accessories themselves are not musical instruments and are not encompassed in the “musical instrument” class. The Board, therefore, denied the motion to amend the identification of goods.

The Board next considered Fender’s motion for summary judgment on the ground of nonuse. An application based on use of the mark in commerce is void if the mark was not used in commerce in connection with the goods identified in the application. As the Board had already decided, Win-D-Fender’s mark was limited to musical instruments and did not include accessories. Fender specifically pointed to an interrogatory response in which Win-D-Fender stated that the products sold under the [...]

Only under Rare Circumstances Can the Patent Trial & Appeal Board Find Proposed Substitute Claims Unpatentable on Its Own

by James M. Oehler | Mar 31, 2022 | Patents

The US Court of Appeals for the Federal Circuit addressed, for the first time, the issue of when the Patent Trial & Appeal Board (Board) may raise a ground of unpatentability that was not advanced by a petitioner in relation to proposed substitute claims. The Court upheld the standard defining the “rare circumstances” in which such a ruling is proper while questioning the Board’s reasoning and application of the standard. Hunting Titan, Inc. v. DynaEnergetics Europe GMBH, Case Nos. 20-2163; -2191 (Fed. Cir. Mar. 24, 2022) (Prost, C.J., Reyna, Hughes, JJ.) (Prost, C.J., concurring).

Hunting Titan challenged DynaEnergetics’ patent in an inter partes review (IPR) based on anticipation and obviousness grounds. The Board found all the original claims of the patent unpatentable as anticipated. DynaEnergetics moved to amend to add proposed substitute claims. Hunting Titan opposed the motion to amend but advanced only obviousness grounds against the proposed substitute claims. The Board determined sua sponte that the proposed substitute claims were unpatentable as anticipated and, therefore, denied the motion to amend. DynaEnergetics requested rehearing, and the Precedential Opinion Panel (POP) reversed the Board’s denial of the motion to amend and determined that Hunting Titan did not prove that the proposed substitute claims were unpatentable.

The POP decided that “only under rare circumstances” should the Board sua sponte raise a ground for unpatentability not advanced by the petitioner in relation to proposed substitute claims. The rare circumstances include only two situations:

When the petitioner is not involved in the motion to amend, such as when a petitioner chooses not to oppose the motion or ceases to participate in the proceeding altogether
When evidence of unpatentability is readily identifiable and persuasive, such as if the substitute claims are unpatentable for the same reasons as the original claims.

The POP stated that in most circumstances, it is best to rely on the adversarial system and expect the petitioner to raise the unpatentability grounds for consideration.

The Federal Circuit upheld the POP’s standard for when the Board may sua sponte find proposed substitute claims unpatentable but also found the POP’s reasoning “problematic” because it placed too much emphasis on the adversarial system. The Court noted that Board proceedings, such as IPRs, are fundamentally a review of an earlier administrative proceeding, as opposed to civil litigation, The POP’s rationale was based on the public interest being served by an adversarial system rather than on the public interest being served by maintaining integrity of the patent system.

The Federal Circuit also questioned the POP’s application of its new standard to the case at hand, noting that the readily identifiable evidence exception should have been applied when the Board found the proposed substitute claims unpatentable for the same reasons it found the original claims to be unpatentable.

In her concurring opinion, Chief Judge Prost noted that “[i]t makes little sense to limit the [Board], in its role within the agency responsible for issuing patents, to the petitioner’s arguments.” Instead, “the Board must determine whether the [...]
