Not a Bullseye: Defendant Must Rebut Presumption That Claims Lacking “Means” Language Don’t Fall Under § 112 ¶ 6

by Paul Devinsky | Mar 31, 2022 | Patents

Reversing a district court finding of indefiniteness under 35 U.S.C. § 112 ¶ 6, the US Court of Appeals for the Federal Circuit found that the district court erred by ignoring unrebutted evidence that the challenged claim terms would have been understood to connote sufficiently definite structure to avoid means-plus-function construction. Dyfan, LLC v. Target Corp., Case No. 21-1725 (Fed. Cir. Mar. 24, 2022) (Lourie, Dyk, Stoll, JJ.)

Dyfan sued Target for infringement of two patents directed to location-based message delivery. During claim construction proceedings, Target argued that certain claim limitations should be construed as means-plus-function limitations and that the specification failed to disclose the requisite corresponding structure. The district court found that three claim terms were subject to § 112 ¶ 6. For the terms “code” and “application,” the court assigned a “special-purpose computer function” as the corresponding structure and found that the specification did not disclose a requisite algorithm for the functions of the computer. The district court also found that the claim term “system” was subject to § 112 ¶ 6 because it recited purely functional language without disclosing sufficient corresponding structure, and that it was unclear which of the recited components performed the recited function. The district court concluded that all three terms were indefinite under § 112 ¶ 2 for lack of corresponding structure. Dyfan appealed.

Reviewing de novo, the Federal Circuit first addressed whether the claim language invoked § 112 ¶ 6. As the Court had stated previously, there is a rebuttable presumption that a claim limitation is not drafted in a means-plus-function format if it does not contain the term “means.” However, that presumption can be overcome if a challenger demonstrates that the term fails to recite sufficiently definite structure. The Court also explained that for purposes of § 112 ¶ 6, certain “nonce words that reflect nothing more than verbal constructs” are tantamount to using the word “means.”

Turning to the case merits, the Federal Circuit first considered the terms “code” and “application.” Given the absence of “means” language, Target was required to show by a preponderance of the evidence that persons of ordinary skill in the art would not have understood those terms to connote structure considering the claim as a whole. The Court found that the district court erred in concluding that Target overcame the presumption that § 112 ¶ 6 did not apply. The Court relied on unrebutted testimony from Target’s expert witness that the district court ignored. The expert testified that both terms would have connoted structure, such as off-the-shelf software. The Court found that this unrebutted testimony demonstrated that neither claim limitation recited purely functional language.

The Federal Circuit explained that the district court failed to follow its 2018 decision in Zeroclick v. Apple. In that case, the Court reversed a district court’s finding that the claim terms “program” and “user interface” invoked § 112 ¶ 6, finding that both terms were references to conventional program code existing in the prior [...]

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 [...]

Re-Poster Child for § 230: Immunity under the CDA for Reposting Content of Another

by Sarah J. Fischer | Mar 31, 2022 | Copyrights

The US Court of Appeals for the First Circuit affirmed a district court’s decision to dismiss claims for defamation under the Communications Decency Act (CDA), 47 USC § 230, and for copyright infringement under the fair use doctrine. Monsarrat v. Newman, Case No. 21-1146 (Kayatta, Lipez, Gelpí, JJ.).

The parties’ dispute arose from a series of posts on a community message board. Residents of the Davis Square neighborhood in Massachusetts maintained a Live Journal forum for several years. In response to a revision of the Live Journal terms of service in 2017, Ron Newman, a member of the community, copied the entirety of the content from the Live Journal forum to another online platform: Dreamwidth. The copied content included a series of allegedly defamatory posts about Jonathan Monsarrat and a post that Monsarrat had copyrighted. Monsarrat sued Newman for both defamation and copyright infringement. Newman moved to dismiss the defamation claim under the CDA, § 230, and the copyright claim under the fair use doctrine. After the district court granted the motions, Monsarrat appealed.

The First Circuit first addressed the defamation claim under § 230. Newman argued that § 230 provided him immunity from defamation. Specifically, § 230 states “[n]o provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.” It also provides a shield from state law claims that would be “inconsistent with this section.” Courts apply a three-part analysis to determine whether a defendant is entitled to immunity under § 230:

Is the defendant a “provider or user of an interactive computer service”?
Is the claim based on “information provided by another information content provider”?
Does the claim treat the defendant “as the publisher or speaker” of that information?

Monsarrat did not challenge the fact that Newman was a “user” under the first prong. Regarding the second prong, the analysis hinged on whether Newman was an “information content provider,” which in turn relied on whether Newman was responsible for the allegedly defamatory content in whole or in part. The factual record showed that Newman did nothing but copy the allegedly defamatory posts that had been created by another. Monsarrat unsuccessfully argued that Newman was responsible because Newman copied the posts from Live Journal to a different digital platform with an allegedly different audience. The First Circuit was not persuaded, ruling that providing essentially the same content on a different platform did not make a defendant responsible for that content under § 230. Regarding the third prong, Monsarrat’s complaint clearly alleged that Newman was acting as a publisher. The Court affirmed the dismissal of the defamation claim under § 230.

Monsarrat’s copyright claim related to a Live Journal post by Monsarrat in the Davis Square forum. He had created a post with a link to Live Journal’s harassment policy, a quotation from the policy and a brief message regarding his attempts to report the abuse he felt he had suffered by other [...]

Outlier? Split Federal Circuit Denies En Banc Review of Written Description Requirement

by Jenny Chen, Ph.D. | Mar 31, 2022 | Patents

The US Court of Appeals for the Federal Circuit denied a patent owner’s request for en banc rehearing of a panel decision that invalidated a patent for lack of written description on the basis that a person of skill in the art would not be able to recognize the clinical efficacy of the claimed dose and thus would not recognize that the inventors were in possession of the claimed invention at filing. Biogen International GMBH, Biogen MA, Inc. v. Mylan Pharmaceuticals Inc., Case No. 20-1933 (Fed. Cir. March 16, 2022) (per curiam) (Moore, C.J., Lourie, Newman, JJ., dissenting).

Biogen owns a patent relating to the drug Tecfidera®. The patent claims a method of treating multiple sclerosis with dimethyl fumarate (DMF) at a specific dose of 480 mg per day via oral administration (DMF480). In the written description, the patent describes a method for treating a neurological disease using DMF and states that the neurological disease can be multiple sclerosis. The patent discloses that an effective dose of DMF for oral administration can be “from about 0.1 g to 1 g per day, 200 mg to about 800 mg per day (e.g., from about 240 mg to about 720 mg per day, or from about 480 mg to about 720 mg per day; or about 720 mg per day).”

Biogen sued Mylan for infringement after Mylan submitted an abbreviated new drug application (ANDA) for a generic version of Tecfidera®. Mylan challenged the validity of the patent based on lack of written description. The district court invalidated the patent, finding that the claimed method lacked written description support because the DMF480 dose was listed only once in the specification and finding that the specification’s focus on basic research and broad DMF-dosage ranges showed that the inventors did not possess a therapeutically effective DMF480 dose at the time of filing. Biogen appealed.

In a 2–1 panel decision, the Federal Circuit affirmed the district court finding, explaining that “a skilled artisan would not have recognized, based on the single passing reference to a DMF480 dose in the disclosure, that DMF480 would have been efficacious in the treatment of MS, particularly because the specification’s only reference to DMF480 was part of a wide DMF-dosage range and not listed as an independent therapeutically efficacious dose.”

Judge O’Malley issued a dissenting opinion, questioning whether the district court erred in requesting clinical data showing efficacy of the claimed DMF480 dose under the written description context.

Biogen timely petitioned for en banc review, raising two questions:

Must a “written description” prove the invention’s efficacy?
Is there a need to repeatedly emphasize elements of the invention in order to satisfy the written description requirement?

The Federal Circuit issued a 6–3 decision denying the en banc petition. Judge Lourie wrote in dissent, joined by Chief Judge Moore and Judge Newman, calling this case “an outlier” at “the farthest end of the spectrum of cases where written description has not been found” given that every claim limitation was expressly described [...]

So You Wanna Play with Copyright? “Joyful Noise” Ostinato Isn’t Original Expression

by Jodi Benassi | Mar 24, 2022 | Copyrights

The US Court of Appeals for the Ninth Circuit affirmed a district court’s order vacating a jury award of damages for copyright infringement and granting judgment as a matter of law, explaining that the musical work alleged to have been copied did not qualify as an original work of authorship but consisted only of “commonplace musical elements.” Marcus Gray PKA Flame et al. v. Katheryn Elizabeth Hudson PKA Katy Perry et al., Case No. 20-55401 (9th Cir. Mar. 10, 2022) (Clifton, Smith, Watford, JJ.)

Key Definitions:

A musical scale is a sequence of musical notes or tones by pitch.
A subset of seven notes is called the minor scale and can be referred to with alphabetic names (A, B, C, etc.) or scale degrees (1, 2, 3, etc.).
An ostinato is a repeating musical figure (for example, 3-3-3-3-2-2).

In 2007, Marcus Gray (Flame) purchased an ostinato and used it in the song “Joyful Noise.” The song was released in 2008. While “Joyful Noise” did not achieve significant commercial success or airtime, it received millions of views online. In 2013, American singer-songwriter Katy Perry created “Dark Horse,” which was a hit, resulting in her performance at the Super Bowl halftime show in 2015.

The “Joyful Noise” ostinato consists of notes, represented as 3-3-3-3-2-2-2-1 and 3-3-3-3-2-2-2-6, whereas Dark Horse’s ostinato contains 3-3-3-3-2-2-1-5. Both have a uniform rhythm and equal note duration in time.

Plaintiffs sued Perry and her co-defendants for copyright infringement. Plaintiffs presented circumstantial evidence that the defendants had a reasonable opportunity to access “Joyful Noise” and that the ostinatos in both songs were substantially similar. Plaintiffs did not present direct evidence that Perry and the others had copied elements of the song, instead relying on testimony from their expert musicologist, Dr. Todd Decker.

Decker testified that the ostinatos were similar in many aspects, but he also testified that there was no single element that caused him to believe the ostinatos at issue were “substantially similar” when viewed “in isolation.” The jury also heard testimony from Perry’s expert, who disagreed altogether that the ostinatos were substantially similar.

The jury found that the defendants had a reasonable opportunity to hear “Joyful Noise” before composing “Dark Horse,” that the two songs contained substantially similar copyrightable expression and that “Dark Horse” used protected material from “Joyful Noise.” The jury found the defendants liable for copyright infringement and awarded $2.8 million in damages. The district court vacated the award and granted judgment as a matter of law to defendants, concluding that the evidence at trial was legally insufficient to show that the “Joyful Noise” ostinato was a copyrightable original expression. The plaintiffs appealed.

The Ninth Circuit explained that because the plaintiffs did not present any direct evidence that the defendants copied the “Joyful Noise” ostinato, they were required to show that the defendants had access to the work and that the ostinatos
