This Mashup Is Not a Place You’ll Go – Seuss Copyright Will ‘Live Long and Prosper’

by | Jan 7, 2021 | ,

Presented with a publishing company defendant’s mashup of Dr. Seuss’ copyrighted works with Star Trek in a work titled Oh, the Places You’ll Boldly Go!, the US Court of Appeals for the Ninth Circuit tackled claims of both copyright and trademark infringement, including the defense of fair use and the use of trademarks in expressive works. The Ninth Circuit reversed the district court’s summary judgment in favor of defendants on the copyright infringement claim and affirmed the district court’s dismissal and grant of summary judgment in favor of defendants on the trademark claim. Dr. Seuss Enterprises, L.P. v. ComicMix LLC, et al., Case No. 19-55348 (9th Cir. Dec. 18, 2020) (McKeown, J.)

Seuss Enterprises owns the intellectual property in the works of late author Theodor S. Geisel, better known as Dr. Seuss. Seuss Enterprises carefully yet prolifically licenses the Dr. Seuss works and brand across a variety of entertainment, media, art and consumer goods, including derivative works of Dr. Seuss’ final book, and graduation favorite, Oh, the Places You’ll Go! When Seuss Enterprises encountered a Kickstarter campaign to raise funds for the Oh, the Places You’ll Boldly Go! mashup work created by ComicMix (a company whose employees include an author of Star Trek episodes), it filed suit for copyright and trademark infringement. The district court granted ComicMix’s motion for summary judgment, holding that the Boldly work was a fair use of Dr. Seuss’s Oh, the Places You’ll Go! and that Seuss Enterprises did not have a cognizable trademark infringement claim under the Lanham Act. Seuss Enterprises appealed.

On appeal, ComicMix asserted its defense of fair use by arguing that its copying of the Dr. Seuss works (described at one point in the record as painstaking attempts to create “identical” illustrations) resulted in a parody of the works. The Ninth Circuit examined the facts under the four non-exclusive factors of fair use reflected in § 107 of the Copyright Act:

  • The purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes
  • The nature of the copyrighted work
  • The amount and substantiality of the portion used in relation to the copyrighted work as a whole
  • The effect of the use upon the potential market for, or value of, the copyrighted work.

Remarking that the outcome of the purpose and character of the use factor influences the assessment of the third and fourth factors, the Ninth Circuit concluded that the Boldly work was not transformative as a parody or otherwise, and that the “indisputably commercial” nature of the work weighed against fair use. The Court explained that a parody exists only if the resulting work critiques or comments on the underlying copyrighted work. The Ninth Circuit cited its decision in another Seuss case (Dr. Seuss Enters. v. Penguin Books), which involved the retelling of the O.J. Simpson murder trial through the lens of The Cat in the Hat. Here, the Court similarly found that Boldly only “evokes” Oh, the Places [...]

“Icy” Guidance on Polaroid Factors

by | Dec 3, 2020 |

In a “somewhat unusual” trademark case involving directly competing products and marks using the same words, the US Court of Appeals for the Second Circuit reversed in part and affirmed in part the grant of summary judgment for the accused infringer on trademark infringement and dilution claims. The Court found that the similarity of the marks and bad faith on part of the accused infringer weighed in favor of finding infringement. Car Freshner Corp. v. American Covers, LLC, Case No. 19-2750 (2d Cir. Nov. 19, 2020) (Newman, J.)

Car Freshner and American Covers both sell car air freshener products. Car Freshner filed a lawsuit against American Covers alleging that Car Freshner’s trademark “Black Ice” was infringed and diluted by American Covers’ sale of air freshener products using the words “Midnight Black Ice Storm.” The district court rejected Car Freshner’s trademark infringement claim, concluding that “Midnight Black Ice Storm” was not similar enough to “Black Ice” to create a likelihood of confusion about the source of the products. The district court also rejected Car Freshner’s trademark dilution claim, concluding that the marks in question were not sufficiently famous. Car Freshner appealed.

On appeal, the Second Circuit reversed the district court’s entry of judgment for American Covers on the trademark infringement claim. Reviewing the trademark infringement claim using the eight Polaroid factors, the Court noted the lack of guidance regarding how much weight to accord each of the factors. Despite this lack of guidance, the Court was particularly persuaded by two of the Polaroid factors: the similarity of the marks, and bad faith on the part of the accused infringer. As to the similarity of the marks factor, the Court noted that “[i]t is extremely unusual for the mark of a junior user to include two identical words of a senior user’s mark in sequence[,]” particularly when both users are competitors in the same market. Despite the differences in packaging between the two products, the Court found that the similarity of the marks weighed heavily in favor of a finding of trademark infringement. As to the bad faith factor, the Court found that emails produced by American Covers, which revealed that its employees specifically chose product names meant to encourage customers to form a connection between American Covers’ products and Car Freshner’s products, were “explicit evidence of bad faith” on the part of American Covers.

As to the dilution claim, the Second Circuit affirmed the district court’s summary judgment finding, concluding that there was no evidence that either of the marks in question was famous.

Practice Note: Although courts have not provided guidance on how to weigh the Polaroid factors in trademark cases, this case demonstrates that two of the factors (similarity of the marks and bad faith on the part of the accused infringer) can be especially persuasive, particularly when the evidence for these factors is strong.

Wave Goodbye to Lost Arguments: Waiver Versus Forfeiture Law

by | Nov 24, 2020 | ,

The US Court of Appeals for the Federal Circuit concluded that a patent owner forfeited claim construction arguments on appeal by not presenting them first to the Patent Trial and Appeal Board for consideration. In re: Google Tech. Holdings LLC, Case No. 19-1828 (Fed. Cir. Nov. 13, 2020) (Chen, J.)

Google submitted an application to the US Patent and Trademark Office (PTO) seeking patent claims covering certain means and methods for transferring content to video-on-demand systems. During examination, the examiner rejected Google’s proposed claims based on obviousness in light of certain references. After receiving a final rejection, Google appealed to the Board, relying heavily on block quotes from the references and proposed claims to argue that the examiner improperly found obviousness.

The Board affirmed the examiner’s rejection. Applying the broadest reasonable interpretation standard, the Board construed two claim terms: “costs” and “network impact.” In defining those terms, the Board noted that Google had not, in the course of appealing the examiner’s decision, “cited to a definition of ‘costs’ or ‘network impact’ in the [s]pecification that would preclude the [e]xaminer’s broader reading.” Google appealed.

Google argued that the Board erred in its constructions. The Federal Circuit never reached the merits, however, instead concluding that Google had not properly presented its arguments first to the PTO. The Court described the oft-forgotten difference between waiver (the voluntary and knowing relinquishment of a right) and forfeiture (the failure to make a timely assertion of a particular right). This case, the Court reasoned, was an example of forfeiture, because Google had failed to urge the claim constructions to the PTO in the first instance.

Google contended that the Federal Circuit should nonetheless review the Board’s determination, because the Board actually ruled on the claim constructions and those issues were ripe for decision before the Court. The Court rejected these arguments, largely because Google identified no excuse for failing to raise the issue earlier, and because the Board’s final decision was not unexpected in the course of the proceedings.

Practice Note: Ultimately, the Court’s opinion presents one approach (perhaps not one consistently followed) regarding what an appellant must do in order to maintain its right to review. Appellees seeking to foreclose appellate review should consider whether, regardless of the Board’s ultimate decision, the appellant appropriately pressed the arguments on the error for which it later seeks appellate review.

Federal Circuit Will Not Second-Guess IPR Institution Denials

by | Nov 11, 2020 | ,

In a series of non-precedential orders, the US Court of Appeals for the Federal Circuit reiterated that it lacks jurisdiction to hear appeals on whether the Patent Trial and Appeal Board properly decided to deny inter partes review (IPR) petitions based on parallel district court litigation. Cisco Systems Inc. v. Ramot at Tel Aviv University, Case Nos. 20-2047, -2049 (Fed. Cir. Oct. 30, 2020); Google LLC v. Uniloc 2017 LLC, Case No. 20-2040 (Oct. 30, 2020); In re: Cisco Systems Inc., Case No. 2020-148 (Fed. Cir. Oct. 30, 2020); Apple Inc. v. Maxell, Ltd., Case No. 20-2132, -2211, -2212, -2213, 21-1033 (Fed. Cir. Oct. 30, 2020).

The 2011 Leahy-Smith America Invents Act (AIA) created various mechanisms for challenging the validity of issued patents in post-grant proceedings before the US Patent and Trademark Office PTO) by adding transitional covered business method and post-grant review proceedings to existing ex parte re-examination, and expanding and renaming inter partes re-examination to inter partes review (IPR).

Under 35 USC §§ 311, 312, a petition for IPR must identify all real parties in interest, identify and support the prior art grounds for challenges to the claims, and provide “such other information as the Director may require by regulation.” Under 35 USC § 314 and 37 CFR 42.4(a), the Board institutes a trial on behalf of the PTO Director, and a “determination by the Director whether to institute an inter partes review under this section shall be final and nonappealable.” In deciding whether to institute the trial, the Board considers, at a minimum, whether a petitioner has satisfied the relevant statutory institution standard. Even when a petitioner has satisfied the institution standard, the Director has statutory discretion under 35 USC 314(a) and 324(a) to deny a petition.

In 2016, the Supreme Court of the United States held in Cuozzo Speed Techs. v. Lee that “the agency’s decision to deny a petition is a matter committed to the Patent Office’s discretion,” and that there is “no mandate to institute review.” The Supreme Court also found that the Director is given broad discretion under 35 USC 315(d) and 325(d) to determine the manner in which “multiple proceedings” before the PTO involving the same patent may proceed, “including providing for stay, transfer, consolidation, or termination of any such matter or proceeding.” Subsequent PTO policies and precedential Board decisions set forth factors affecting the case-specific analysis of whether to institute an AIA proceeding, and particularly a follow-on or serial petition, or discretionary denial due to the timing of parallel district court proceedings.

In Cisco v. Ramot, the Board denied Cisco’s petitions to institute IPRs against two patents that Ramot had asserted against it in a district court case. The decisions denying Cisco’s petitions cited the Board’s discretion under 35 USC § 314(a) not to institute review and relied on the factors determining whether efficiency, fairness and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding. Specifically, the Board [...]

Cookie Trade Dress Infringement Case Crumbles in Face of Functionality Challenge

by | Oct 29, 2020 |

The US Court of Appeals for the Third Circuit found that trade dress protection did not extend to the design of a chocolate-dipped, stick-shaped cookie, because the product configuration was useful. Ezaki Glico Kabushiki Kaisha v. Lotte Int’l America Corp., Case No. 19-3010 (3d Cir. Oct. 8, 2020) (Bibas, J.).

Ezaki Glico is a Japanese confectionary company that makes and sells the snack food Pocky, which is a thin, stick-shaped cookie with one side dipped in chocolate (or a flavored cream) and the other uncoated. Pocky cookies have been sold in the United States for more than 40 years, during which time Ezaki Glico obtained two trade dress registrations for the Pocky design and a patent for a “Stick Shaped Snack and Method for Producing the Same.”

In 2015, Ezaki Glico sued its competitor, Lotte, alleging that Lotte’s similarly designed cookie, Pepero, infringed the Pocky trade dress. The district court granted Lotte’s motion for summary judgment, finding the Pocky product configuration functional and therefore not protected by trade dress. Ezaki Glico appealed.

Ezaki Glico argued that the Pocky trade dress is not functional because it is not essential to its design. The Third Circuit disagreed, stating “that test is too narrow.” The Court explained that functionality applies to features that are useful, even if they are not necessarily essential. The Court enumerated four indicators of functionality:

  • Evidence that the feature or design makes the relevant product work better
  • Examples of marketing materials touting the usefulness of the feature or design
  • Existence of a utility patent
  • Availability of other designs.

The Third Circuit found that most of these factors supported the finding of functionality. First, the design makes the product work better because “[e]very feature of Pocky’s registration relates to the practical functions of holding, eating, sharing, or packing the snack.” Ezaki Glico’s advertisements also promoted the functional features of Pocky’s design: they featured phrases such as “convenient design,” “the no mess handle of the Pocky Stick,” and “easier for multi-tasking without getting chocolate on your hand.” Likewise, the Court was unpersuaded by Ezaki Glico’s evidence of alternative designs, finding that “[e]very aspect of Pocky is useful. The nine other designs do not make it less so.”

The existence of the utility patent, however, was not a supporting factor in the functionality analysis. The Third Circuit explained that “the patent’s innovation is a better method for making the snack’s stick shape. The method is useful for making the shape whether or not the shape itself is useful for anything.” Although the district court improperly considered this factor in its analysis, the Third Circuit noted that the misstep was “immaterial” given that the district court ultimately reached the correct conclusion.

Practice Note: It is not necessary for a design feature to be essential for it to be considered functional. Trade dress may be considered functional—and therefore not protectable via trademark law—if it is merely useful to the design.

PTO Seeks Comments on Proposed Rulemaking for Denying Patent Reviews

by | Oct 29, 2020 | ,

The US Patent and Trademark Office (PTO) requested public comments on considerations for instituting trials under the Leahy-Smith America Invents Act (AIA). Comments are due by November 19, 2020.

Patent practitioners have grown accustomed to reviewing the PTO Patent Trial and Appeal Board (Board) administrative guide, precedential or informative opinions, and other published filings and decisions to discern best practices for filing petitions for and defending against inter partes review, post-grant review, covered business method and derivation proceedings before the Board. For example, the latest Board Consolidated Trial Practice Guide (Nov. 2019) (CTPG) is available here. The PTO is considering codifying or modifying its current policies and practices through formal rulemaking and wishes to gather public comments on its current approach and other approaches suggested by stakeholders.

PTO policies and Board decisions such as General Plastic, Valve Corp. I, Valve Corp. II, NHK Spring and Fintiv set forth factors for analyzing whether to institute an AIA proceeding (and particularly a follow-on or serial petition) or issue a discretionary denial due to the timeline for parallel district court proceedings. Many of these policies and cases are also discussed in the CTPG. The PTO already has received input from stakeholders on these policies that expand on the PTO director’s discretionary authority to institute an AIA trial. Most stakeholder comments suggested that the case-specific analysis outlined in precedential opinions and the CTPG achieves the appropriate balance and reduces gamesmanship—for example, by ensuring that AIA proceedings do not create excessive costs and uncertainty for the patent owner or the system, while allowing meritorious challenges to patents to be heard. However, some stakeholders have proposed that the PTO adopt brightline rules, regardless of the case-specific circumstances, to:

  • Use its discretion to preclude claims from being subject to more than one AIA proceeding
  • Permit more than one AIA proceeding only if the follow-on petitioner is unrelated to the prior petitioner
  • Place no limits on the number of petitions that can be filed or the number of AIA trials that can be instituted against the claims of a patent, so long as the petition complies with statutory timing requirements and the institution threshold of showing that at least one claim of the patent is unpatentable
  • Preclude institution of an AIA trial against challenged claims if the patent owner opposes institution and a related district court or US International Trade Commission (ITC) action (in which any of the challenged claims are or have been asserted against the petitioner, the petitioner’s real-party-in-interest or a privy of the petitioner) is unlikely to be stayed
  • Eliminate any consideration of the status of any district court or ITC actions involving the challenged patent, so long as the petition complies with statutory timing requirements and the institution threshold.

These contrasting views prompted the PTO to issue a request for comments on the factors that should be considered as part of a balanced assessment of the relevant circumstances when exercising its discretion to institute an AIA trial. The PTO [...]

Only Human: Broadest Reasonable Interpretation Standard Applies to Intentionally Expired Patent

by | Oct 22, 2020 | ,

Affirming an invalidity finding by the Patent and Trial Appeal Board (PTAB), the US Court of Appeals for the Federal Circuit found that the claims of the now-expired patent should be construed under the broadest reasonable interpretation (BRI) standard, and not under the Phillips standard, because the patent owner intentionally gave up the remainder of the patent term only after the appeal was fully briefed. Immunex Corp. v. Sanofi-Aventis U.S. LLC, Case Nos. 19-1749, -1777 (Fed. Cir. Oct. 13, 2020) (Prost, C.J.).

Immunex owns a patent directed to human antibodies that inhabit certain receptors to treat inflammatory diseases such as arthritis. After being sued for infringement, Sanofi and Regeneron (collectively, Sanofi) requested inter partes review (IPR) of the patent, which the PTAB instituted. Based on the IPR filing date and because the patent was unexpired during the pendency of the IPR proceeding, the PTAB used the BRI standard to construe various claim terms. Had the patent been expired, the PTAB would have used the more stringent Phillips standard to construe the claims. Ultimately, the PTAB found all of the challenged claims unpatentable. Immunex appealed.

After appellate briefing was complete, Immunex filed a terminal disclaimer of its patent. The US Patent and Trademark Office accepted the terminal disclaimer, and as a result the patent term expired approximately two months before oral argument. Immunex then filed a citation of supplemental authority informing the Federal Circuit of the terminal disclaimer and asking the Court to change the applicable claim construction standard from BRI to Phillips.

The Federal Circuit found that the application of the BRI standard to Immunex’s patent was appropriate. Although the PTAB currently applies the Phillips claim construction standard in all newly filed IPRs, at the time that Sanofi filed its IPRs, the PTAB applied the Phillips standard only to expired patents. For unexpired patents, it applied the BRI standard. The Court noted that the use of the Phillips standard in cases where the patent expired during the appellate process should not be an absolute, particularly when the patent term expired at an unexpected early date, such as through the filing of a terminal disclaimer.

The Federal Circuit further affirmed the PTAB’s claim construction under the BRI standard and the invalidity finding predicated on that claim construction. The issue on appeal was whether a “human antibody” must be entirely human (as asserted by Immunex) or whether it may also be “partially human,” including “humanized” (as asserted by Sanofi and construed by the PTAB). The Court agreed with the PTAB and found that the patent’s specification supported the conclusion that the BRI of “human antibody” “includes both fully human and partially human antibodies.” The Court also found that “human antibodies” in the context of the patent-in-suit is a broad category that encompasses both partially and completely human antibodies. The Court therefore affirmed the PTAB’s finding.

The Federal Circuit also commented on the PTAB’s departure from an earlier claim construction ruling by a district court in which “human” was construed to mean “fully [...]

Supreme Court to Consider Whether PTAB Judges Are Unconstitutionally Appointed

by | Oct 22, 2020 |

The Supreme Court of the United States agreed to consider whether Patent Trial and Appeal Board (PTAB) judges are unconstitutionally appointed. The United States of America v. Arthrex, Inc., Case Nos. 19-1452, -1458, -1459 (Supr. Ct. October 13, 2020) (certiorari granted).

In what quickly turned into a controversial decision, the US Court of Appeals for the Federal Circuit held the appointment of administrative patent judges at the PTAB unconstitutional. Arthrex, Inc. v. Smith & Nephew, Inc.  The Federal Circuit found that PTAB judges were appointed as if they were “inferior officers” but vested by the PTAB with authority that is reserved for Senate-confirmed “principal officers.” Smith & Nephew, Arthrex and the United States of America petitioned the Supreme Court for review of the decision.

The questions presented are:

  1. Whether, for purposes of the Appointments Clause, US Const. Art. II, § 2, Cl. 2, administrative patent judges of the US Patent and Trademark Office are principal officers who must be appointed by the president with the Senate’s advice and consent, or “inferior officers” whose appointment Congress has permissibly vested in a department head.
  2. If administrative patent judges are principal officers, whether the court of appeals properly cured any Appointments Clause defect in the current statutory scheme prospectively by severing the application of 5 USC 7513(a) to those judges.

Eye Don’t: No Counterfeiting Without Likelihood of Confusion

by | Oct 15, 2020 |

Referring to the act of counterfeiting as “hard core” or “first degree” trademark infringement, the US Court of Appeals for the Ninth Circuit for the first time confirmed that the Lanham Act requires a likelihood of confusion in order for the trademark holder to prevail on a counterfeiting claim. Arcona, Inc. v. Farmacy Beauty, LLC, et al., Case No. 19-55586 (9th Cir. Oct. 1, 2020) (Lee, J.) In doing so, the Court affirmed a grant of summary judgment in favor of defendant Farmacy Beauty in a counterfeiting action brought by skin care brand Arcona.

Arcona’s counterfeiting claims (which remained in the district court action after Arcona requested dismissal of its trademark infringement and unfair competition claims) stemmed from Farmacy Beauty’s use of the term EYE DEW on its skincare products, which Arcona asserted to be counterfeit versions of its eye cream sold in the United States under the registered EYE DEW trademark. The district court, however, found that dissimilar packaging and branding made it “implausible” that consumers would be tricked into believing that Farmacy’s EYE DEW product was actually one of Arcona’s skin care products, and granted partial summary judgment for Farmacy on the counterfeiting claim. Arcona appealed.

Arcona argued that it was not required to show a likelihood of consumer confusion with respect to the parties’ EYE DEW eye creams in order to pursue its trademark counterfeiting claim. The Ninth Circuit starkly disagreed, finding that the plain language of the Lanham Act, 15 USC § 1114, expressly states that likelihood of confusion is a requirement for a counterfeiting claim.

The Ninth Circuit also rejected Arcona’s alternative argument, that there should be a presumption of likelihood of confusion based on the parties’ use of the identical mark EYE DEW. The Court explained that in a claim of counterfeiting—even with identical trademarks—there is no presumption of consumer confusion if the products themselves are not identical. Here, evidence demonstrated that the parties sold their respective EYE DEW products in very different packages, with Arcona’s eye cream being in a “tall, cylindrical, silver bottle encased in a slim, cardboard outer box,” and Farmacy’s eye cream sold in a “short, wide, white jar, along with a squarish outer box.” In reviewing the parties’ respective products as a whole, including prominent displays of the respective house marks FARMACY and ARCONA, as well as differences in packaging, size, color, shape and “all other attributes,” the Court determined that the parties’ products were not identical and that there was no presumption of consumer confusion.

The Ninth Circuit concluded that summary judgment of no counterfeiting was proper because there was no genuine dispute of material fact about the likelihood of consumer confusion factor. The Court acknowledged that the parties’ eye cream products do compete in the same space and in the same geographic markets, but explained that a claim of counterfeiting nevertheless requires that the parties’ marks be “considered in their entirety and as they appear in the marketplace.” Noting that the available evidence demonstrated significant differences between [...]

Logic to Modify: Even Deceptive Intent Does Not Bar Inventorship Correction

by | Sep 16, 2020 |

The US Court of Appeals for the Federal Circuit vacated a district court invalidity determination finding that judicial estoppel prevented a patent owner from relisting an inventor previously removed for strategic litigation purposes. Egenera, Inc. v. Cisco Sys., Inc., Case Nos. 19-2015, -2387 (Fed. Cir. Aug. 28, 2020) (Prost, C.J.).

Egenera sued Cisco for infringement of a patent directed to a reconfigurable virtual network that included a “logic to modify” and transmit received messages. In response Cisco petitioned for inter partes review (IPR). During the IPR’s pendency, Egenera realized that all claim limitations were conceived of before inventor Schulter began working at the company, and petitioned the US Patent and Trademark Office (PTO) to remove Schulter as a listed inventor. The Patent and Trial Appeal Board (PTAB) declined to institute Cisco’s IPR, and the PTO granted Egenera’s petition to remove Schulter shortly thereafter.

During the litigation, the district court construed the patent claims’ “logic” terms as means-plus-function elements and concluded that the “logic to modify” limitation corresponded to a “tripartite structure” described in the specification. Cisco then asserted invalidity under pre-America Invents Act (AIA) § 102(f), contending that Schulter invented the tripartite structure, and that the patent therefore did not list all inventors. Egenera attempted to re-correct inventorship to include Schulter, but the court rejected the attempt. The district court found the patent invalid under § 102(f), reasoning that judicial estoppel precluded Egenera from “resurrecting” Schulter’s inventorship. Egenera appealed both the means-plus-function construction and the judicial estoppel finding.

The Federal Circuit first addressed whether Egenera could correct inventorship absent any judicial estoppel. The Court looked to the plain meaning of post-AIA § 256, which provides that “the error of omitting inventors . . . shall not invalidate the patent . . . if it can be corrected.” Notably, post-AIA § 256 removed the requirement that an inventorship error occur “without . . . deceptive intent.” The Federal Circuit stated it plainly: “‘Error’ is simply the incorrect listing of inventors” and does not exclude even deceptive intention. The Court explained that the inequitable conduct rules provide a safety valve for such actions, not § 256. The Court also noted that at the time Egenera removed Schulter as an inventor, no one had argued that “logic to modify” was means-plus-function language, which it presumptively was not. Egenera’s preferred construction of that term was consistent with its assertion that Schulter was not an inventor. The omission of Schulter as inventor was thus an “error” within the scope of § 256.

The Federal Circuit next turned to whether Egenera was judicially estopped from relisting Schulter as an inventor. Applying the First Circuit’s New Hampshire factors, the Federal Circuit looked to whether Egenera’s positions were inconsistent, whether its first position was successfully accepted by the court, and whether Egenera would derive an unfair advantage if not estopped. The Federal Circuit found that the district court erred in finding Egenera’s changing inventorship positions inconsistent. The Court explained that inventorship is complex and can depend on claim [...]
