Analogous Art Includes Reference a Skilled Artisan Would Reasonably Consult

Addressing the standard for determining whether a prior art reference constitutes analogous art for purposes of an obviousness analysis, the US Court of Appeals for the Federal Circuit vacated and remanded a Patent Trial and Appeal Board decision that a reference was not analogous. The Court explained that the Board did not consider the purpose and problems to which the prior art and challenged patent relate. Donner Tech., LLC v. Pro Stage Gear, LLC, Case No. 20-1104 (Fed. Cir. Nov. 9, 2020) (Prost, C.J.)

Pro Stage owns a patent directed to an improved guitar effects pedalboard. Guitar effects pedals are electronic devices that affect the amplified sound of a guitar. The pedals are controlled by foot operation switches in order to leave the user’s hands free to play the instrument. When multiple pedals are used, they must be interconnected by cables, which are typically daisy-chained between each separate pedal. Once interconnected, the pedals are placed on a wooden pedalboard and covered with foam so that the cables are not exposed. This leads to difficulty when swapping or adding new pedals because the foam must be removed from the board and the cables repositioned. Pro Stage’s patent attempts to remedy this issue by elevating one side of the pedalboard from the stage floor and providing a mounting surface and cable connection openings such that cables can pass beneath the mounting surface, as demonstrated by the patent figures shown below.

Donner petitioned for inter partes review of the patent, challenging various claims as obvious under 35 USC §103. Donner asserted three grounds of invalidity, all relying at least in part on the teachings of the Mullen patent. Mullen relates to an improved structure for supporting one or more electrical relays and for providing wiring-channel space for receiving wires connected to the relays in order to connect the relays to various control circuits. As part of its petition, Donner claimed that certain embodiments of Mullen (below), disclose a structure that is analogous to the structure claimed in the challenged patent.

The Board rejected that Donner’s obviousness challenges, finding that Donner did “not put forth any argument or evidence to explain what would have compelled a pedalboard inventor in 1999 or 2000 to consider potential solutions arising from early 1970s-era relay technologies,” notwithstanding arguments, expert and other testimony, and other evidence submitted by Donner to the contrary. Donner appealed.

The Federal Circuit reversed, explaining the relevant tests to analyze whether a prior art reference is analogous. The two separate tests are (1) whether the art is from the same field of endeavor, regardless of the problem addressed, and (2) if the reference is [...]

PTO Exam Guide: Post Booking.com, Generic.com Terms Still Face Uphill Battle for Registration

Addressing the Supreme Court of the United States’ ruling in USPTO v. Booking.com B.V., the US Patent and Trademark Office (PTO) recently issued guidance on the examining procedures for “generic.com terms.” (Examination Guide No. 3-20, Generic.com Terms after USPTO v. Booking.com, October 2020.)

Booking.com had been engaged in a prolonged battle to secure registration for its BOOKING.COM trademark in connection with hotel reservation services. Earlier this year, the Supreme Court addressed the issue in Booking.com, rejecting the PTO’s proposed per se rule that a generic term combined with a generic top-level domain (a “generic.com term”) is necessarily generic and therefore ineligible for trademark protection. As the Supreme Court concluded, “[W]hether any given ‘generic.com’ term is generic . . . depends on whether consumers in fact perceive that term as the name of a class or, instead, as a term capable of distinguishing among members of the class.”

In light of this holding, the PTO issued Exam Guide 3-20, which outlines new guidance for examining generic.com terms. The PTO emphasized that the registrability of generic.com terms should be assessed on a case-by-case basis, but that these terms would often face an uphill battle for registration: “[G]iven the nature of these terms, the available evidence will likely support a conclusion that they are, at least, highly descriptive, and thus consumers would be less likely to believe that they indicate source in any party. Thus, for generic.com terms, applicants will generally have a greater evidentiary burden to establish that the proposed mark has acquired distinctiveness.”

The procedure for refusing registration of a generic.com term remains largely unchanged. Typically, an examining attorney cannot issue an initial refusal for genericness; the office action should instead refuse registration for mere descriptiveness under Trademark Act Section 2(e)(1). Depending on the examining attorney’s assessment of whether the relevant generic.com term is even capable of serving as a source identifier, the office action may include language suggesting (or advising against) a claim of acquired distinctiveness under Section 2(f) or amendment to the supplemental register.

Applicants seeking registration for a generic.com term on the principal register under Section 2(f) should be prepared to present substantial evidence that consumers recognize the mark as a source identifier, including, for example:

  • Consumer surveys
  • Consumer declarations
  • Evidence as to the duration, extent and nature of the mark’s use
  • Advertising expenditures.

The PTO warned that evidence of five years’ use or reliance on a prior registration alone is likely insufficient. Additionally, surveys should be accompanied by a report outlining “the procedural aspects of the survey and statistical accuracy of the results, . . . [i]nformation regarding how the survey was conducted, the questionnaire itself, the universe of consumers surveyed, the number of participants surveyed, and the geographic scope of the survey.” If the examining attorney believes the generic.com term is capable of functioning as a trademark but the proffered evidence is insufficient to establish acquired distinctiveness, the examining attorney may allow the applicant to amend the registration to the supplemental register.

Federal Circuit Will Not Second-Guess IPR Institution Denials

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 [...]

Venue in Hatch-Waxman Cases Limited to District Where ANDA Is Submitted

The US Court of Appeals for the Federal Circuit found that in cases brought under the Hatch-Waxman Act, for purposes of determining venue, infringement occurs only in districts where actions related to the submission of an abbreviated new drug application (ANDA) occur, and not in all locations where future distribution of the generic products specified in the ANDA is contemplated. Valeant Pharmaceuticals North American LLC v. Mylan Pharmaceuticals Inc., Case No. 19-2402 (Fed. Cir. Nov. 5, 2020) (O’Malley, J.).

Valeant holds a new drug application for the brand name drug Jublia®, which is used to treat toenail fungal infections. In 2018, Mylan Pharmaceuticals Inc. (MPI) executed an ANDA seeking approval to market a generic version of Jublia®. MPI sent the ANDA from its West Virginia corporate office to the US Food and Drug Administration, located in White Oak, Maryland. The ANDA included a Paragraph IV certification that the Orange-Book-listed patents for Jublia® were invalid, unenforceable or would not be infringed by the ANDA product. After the ANDA was filed, Valeant filed suit in the District of New Jersey against MPI, Mylan Inc. and Mylan Laboratories Ltd. (MLL) pursuant to the Hatch-Waxman Act, alleging infringement of the Orange-Book-listed patents. Valeant also filed an essentially identical lawsuit in the Northern District of West Virginia against the same three defendants. MPI is a West Virginia corporation with a principal place of business in Morgantown, West Virginia. Mylan Inc. is a Pennsylvania corporation with a principal place of business in Canonsburg, Pennsylvania. MLL is an Indian corporation with a principal place of business in Hyderabad, India.

The Mylan entities moved to dismiss the New Jersey litigation, arguing that venue was improper under 28 USC § 1400(b) because none of the Mylan defendants reside or have a regular and established place of business in New Jersey, and the only alleged act of infringement (submission of the ANDA) did not occur in New Jersey. In response, Valeant argued that it was unduly narrow to limit “act of infringement” to the act of submitting the ANDA, and that the court should consider the Mylan entities’ planned future acts, which included acts of infringement in New Jersey. The district court granted the Mylan entities’ motion based on improper venue, finding that the ANDA was submitted from West Virginia and thus venue was proper there. Valeant appealed.

The two issues presented on appeal were the proper venue in Hatch-Waxman cases after TC Heartland v. Kraft Foods, and the proper venue for patent cases brought against foreign entities. Starting with the first issue, the Federal Circuit explained that determining whether venue is proper under § 1400(b) in a district other than the state in which a defendant is incorporated requires determining where the defendant committed acts of infringement. Under the Hatch-Waxman Act, it is an act of infringement to submit an ANDA for a drug claimed in a patent if the purpose of the submission is to obtain approval to engage in commercial activities related to the drug before [...]

Sticky Situation? Circumstantial Evidence Can Support Intent to Confuse in Trade Dress Claims

The US Court of Appeals for the 11th Circuit reversed a district court’s grant of summary judgment for the defendant on trade dress infringement and trade dress dilution claims, finding that evidence relating to the likelihood of confusion was not viewed in the light most favorable to the plaintiff. However, the Court affirmed the grant of summary judgment for the defendant on the plaintiff’s false advertising claims because the allegedly deceptive advertising was not material to consumer purchasing decisions. J-B Weld Co., LLC v. Gorilla Glue Co., Case No. 18-14975 (11th Cir. Oct. 20, 2020) (Tjoflat, J.) (Carnes, J., concurring).

J-B Weld and Gorilla Glue are competitors specializing in heavy-duty adhesive products. Gorilla Glue introduced an adhesive under the brand name GorillaWeld that mimicked the packaging of a J-B Weld product. Gorilla Glue advertised GorillaWeld as a steel bond epoxy based on the strength of the bond and its similarity to an epoxy-group polymer, even though the product was not a chemical epoxy and did not contain any steel. J-B Weld sued, alleging trade dress infringement based on the Lanham Act and Georgia law, trade dress dilution based on Georgia law, and false advertising under the Lanham Act. The district court granted Gorilla Glue summary judgment on all claims, finding no trade dress infringement or dilution based on insufficient evidence of likelihood of confusion, and no false advertising because the evidence did not demonstrate that Gorilla Glue’s steel bond epoxy claim was material to consumer purchasing decisions. J-B Weld appealed, arguing that the district court did not properly view the evidence in the light most favorable to J-B Weld.

The 11th Circuit reversed on the trade dress infringement and dilution claims and affirmed on the false advertising claim. On the trade dress infringement claims, the 11th Circuit found that the district court did not view the evidence in the light most favorable to J-B Weld in analyzing the likelihood of confusion between the respective trade dress of J-B Weld and GorillaWeld, as required in the context of summary judgment. The 11th Circuit found that the district court did not properly credit evidence relevant to the similarity of the designs, Gorilla Glue’s intent and instances of actual confusion. For example, despite multiple similarities between the J-B Weld and GorillaWeld packages (including a V-shape tube arrangement and the use, emphasis and location of certain text), the district court found that the presence of the Gorilla Glue logo, brand name and color scheme negated a finding of similarity. The 11th Circuit deemed this finding error in the context of summary judgment. The Court also determined that communications from Gorilla Glue’s packaging design team that repeatedly referenced J-B Weld’s packaging and expressed a desire to use similar elements (including a communication in which a Gorilla Glue employee referred to the GorillaWeld design as a “knock off”) were improperly ascribed to innocuous motives based on self-serving testimony from a Gorilla Glue employee. As the Court explained, summary judgment required drawing all inferences in the light [...]

Too Good to Be True? Federal Circuit Demands Evidence of Reliance on Favorable Ruling, Stipulation

The US Court of Appeals for the Federal Circuit held that notwithstanding a stipulation on claim construction, a party may still induce infringement absent proof that it actually relied on the stipulation, and that mere inaction, absent an affirmative act to encourage infringement, cannot be the basis for a claim of inducement. The Federal Circuit also affirmed the district court’s reduction of the jury’s damages award to $0 despite a finding of direct infringement because the plaintiff failed to prove damages. TecSec, Inc. v. Adobe Inc., Case Nos. 19-2192, -2258 (Fed. Cir. Oct. 23, 2020) (Taranto, J.).

TecSec owns several patents on systems and methods for multi-level security for network-distributed files. TecSec sued Adobe (among other defendants) in this now-10-year-old-case, which the Federal Circuit has considered several times. As relevant here, the district court entered a claim construction in 2011 that led to a stipulation of non-infringement, and the Federal Circuit reversed that claim construction in 2013. On remand, the district court barred TecSec from introducing evidence of inducement in the 2011–2013 period on the grounds that it was reasonable for Adobe to have relied on the district court’s ruling and the stipulation. On the new claim construction, Adobe stipulated to one act of direct infringement. Adobe also moved for summary judgment of patent ineligibility, which the district court denied, stating that its rationale supported judgment for TecSec that the patents claimed eligible subject matter. At trial, the jury found that the claims were valid and that Adobe directly infringed but did not induce infringement. The jury awarded TecSec $1.75 million in damages. On Adobe’s post-trial motion, the district court reduced the damages award to $0 because TecSec had not proved inducement and had proved no damages associated with the single act of direct infringement. Both parties appealed.

Inducement

The Federal Circuit reversed the district court’s decision on Adobe’s motion in limine barring inducement evidence for the 2011–2013 period. The district court’s primary rationale for granting the motion had been the reasonableness of Adobe’s reliance on the claim construction order and stipulation of non-infringement. However, the Federal Circuit reasoned that the intent prong of inducement is a subjective inquiry, and that inducement could still be found upon a showing that Adobe subjectively believed that the claim construction order was wrong and would subsequently be reversed.

Jury Instructions

The Federal Circuit next addressed two challenges by TecSec to jury instructions. The first instruction was predicated on three facts: (i) that Adobe had admitted that a certain sequence of steps constituted direct infringement, (ii) that Adobe had performed the steps on at least one occasion, and (iii) that “the parties agree that the one time for which Adobe had admitted infringement . . . occurred before TecSec filed its lawsuit.” The Court found that this instruction was factually accurate and therefore not erroneous. The second instruction explained that inducement required “an affirmative act to encourage infringement,” and that “[e]vidence of mere inaction, or a failure to stop or prevent infringement, does not [...]

No Stay, But Please Fix

The US Court of Appeals for the Federal Circuit denied a motion to stay issuance of a mandate while a petition for certiorari regarding patentability under § 101 was pending before the Supreme Court of the United States, finding no irreparable harm if it did not do so. American Axle & Manufacturing, Inc. v. Neapco Holdings LLC, Case No. 18-1763 D.I. 139 (Fed. Cir. Oct. 23, 2020) (Dyk, J.) (Moore, J., concurring). In her concurrence, Judge Moore encouraged the Supreme Court to grant certiorari in order to clarify the scope of § 101.

This decision was the fourth opinion issued by the Federal Circuit in this case. In the Court’s first opinion, a divided panel affirmed that method claims for a mechanical invention were invalid under 35 USC § 101. American Axle & Manufacturing I. The patent owner, American Axle, filed a petition for rehearing and a petition for rehearing en banc. American Axle & Manufacturing II. Several amicus briefs were filed, including one by former Federal Circuit Chief Judge Paul R. Michel. In view of these petitions and amicus briefs, the original panel modified and re-issued its opinion to affirm that certain claims were invalid and to reverse its holding that one claim was invalid. Subsequently, the full Federal Circuit denied the petition for a rehearing en banc, polling 6–6 and demonstrating the Court’s division on the application and scope of § 101.

American Axle filed a petition for certiorari at the Supreme Court and sought a stay from the Federal Circuit of the issuance of the mandate. The Federal Circuit denied a stay, citing Rule 41 of the Federal Rules of Appellate Procedure, which “provides that a motion for stay of the mandate ‘must show that the petition would present a substantial question and that there is good cause for a stay.’” Fed. R. App. P. 41(d)(1). The Court explained that a three-prong test determines whether a stay in a patent case is appropriate under this rule. The applicant must show (1) a reasonable probability that four justices will grant certiorari, (2) a fair prospect that the Supreme Court will reverse judgment, and (3) a likelihood that irreparable harm will result if the stay is denied.

Relying exclusively on irreparable harm, the Federal Circuit denied a stay. With respect to the invalid patent claims, the Court explained that a stay was not warranted because no further action was required by the district court. The Court dismissed American Axle’s argument that it would have to recall its mandate if reversed by the Supreme Court, explaining that this occurrence is common for every case that is reversed. With respect to the valid patent claim, the Court explained that the burden of litigation and litigation expenses is insufficient to show irreparable harm. Thus, the Court dismissed American Axle’s motion to stay the mandate.

Judge Moore filed a concurring opinion asking the Supreme Court to grant certiorari. Moore explained that the Supreme Court often grants cases where there is a [...]

First-to-File Rule Must Be Followed Unless Compelling Circumstances Justify Exception

Vacating and remanding a district court’s decision not to transfer a case, the US Court of Appeals for the Federal Circuit granted a petition for a writ of mandamus because the district court did not consider whether the first-to-file rule favored keeping the case in the second-filed court. In re: Nitro, Case No. 20-142 (Fed. Cir. Oct. 28, 2020) (Reyna, J.).

In 2018, Cameron International filed a suit against Nitro in the Southern District of Texas alleging that Nitro’s fracturing-fluid delivery systems infringed three of Cameron’s patents. In February 2020, Cameron filed a second suit against Nitro in the Western District of Texas, alleging that the same accused products infringed two of Cameron’s other related patents. Relying on the first-to-file rule, which generally dictates that the court in which an action is first filed is the appropriate court to determine whether subsequently filed cases involving substantially similar issues should proceed, Nitro moved the Western District of Texas to decline jurisdiction or transfer the action to the Southern District of Texas.

The district court rejected the application of the first-to-file rule, but not because the two cases lacked substantial overlap. Instead, the district court relied on US Court of Appeals for the Fifth Circuit precedent stating that even where there is such overlap, the court still must determine whether there are “sufficiently ‘compelling circumstances’ to avoid the rule’s application.” The district court determined that it was appropriate to use a balance of the traditional transfer factors to make that determination, concluding that when a balance of transfer factors “does not weigh in favor of transfer[,] . . . compelling circumstances exist in order to avoid application of the first-to-file rule.” Applying this standard, the district court denied Nitro’s motion. The district court found that although two of the factors (relative ease of access to sources of proof, and local interest in having localized interests decided at home) favored transfer, the administrative difficulties flowing from court congestion, co-pending suits against another defendant involving the same patents, and the district court’s ability to more quickly schedule a trial weighed against transfer. Nitro filed for mandamus.

Proceeding from the district court’s premise that transfer pursuant to the first-to-file rule would be proper absent the existence of compelling circumstances, and that a balance of the transfer factors can support such an exception, the Federal Circuit explained that consideration of Nitro’s petition turned on the correctness of the district court’s application of those factors. The Court explained that the district court had it backwards by concluding that the first-to-file rule is only applicable when the balance of factors favors the first-filed court. Instead, the proper inquiry is that unless the balance of transfer factors favors keeping the case in the second-filed court, there are no compelling circumstances to keep the case in the second-filed court.

The Federal Circuit found that the district court did not resolve the critical issue of whether a balance of the factors favored the second-filed court. The Federal Circuit explained that although [...]

Trademark Cancellation Is Appropriate Sanction for Misconduct

In upholding a grocery store chain’s standing to petition for cancellation of a US trademark registration, the US Court of Appeals for the Federal Circuit affirmed the Trademark Trial and Appeal Board’s (TTAB’s) express authority to impose cancellation of a trademark by default judgment as a sanction in a TTAB proceeding. Corcamore, LLC v. SFM, LLC, Case No. 19-1526 (Fed. Cir. Oct. 27, 2020) (Reyna, J.).

SFM owns US federal trademark registrations for the mark SPROUTS for use in connection with its retail grocery store services. SFM filed a petition to cancel Corcamore’s US trademark registration for the mark SPROUT for use in connection with vending machine services, alleging a likelihood of consumer confusion with SFM’s prior trademark rights. The TTAB denied Corcamore’s motion to dismiss the cancellation petition for lack of standing. Relying on Empresa Cubana del Tabaco v. General Cigar Co., the TTAB confirmed SFM’s standing based on its “real interest” in the cancellation petition and a “reasonable belief of damage” caused by the continued registration of Corcamore’s SPROUT trademark.

Following the TTAB’s denial of its motion to dismiss, Corcamore undertook a series willful, bad-faith procedural maneuvers that resulted in two separate sanctions. When Corcamore’s further procedural misconduct violated both sanctions orders, the TTAB entered default judgment cancelling Corcamore’s SPROUT trademark registration. Corcamore appealed.

On appeal, Corcamore alleged that the TTAB (1) erred in applying Empresa Cubana rather than the Supreme Court of the United States’ Lexmark v. Static Control framework in affirming SFM’s standing, and (2) abused its discretion in granting default judgment as a sanction. On the issue of standing, the Federal Circuit rejected the TTAB’s “unduly narrow” conclusion that the Supreme Court’s Lexmark framework was inapplicable, since Lexmark related to a claim of false advertising under § 1125(a) of the Lanham Act, while Empresa Cubana addressed the right to bring a cancellation proceeding under § 1064. The Federal Circuit concluded that Lexmark applied to § 1064 and § 1125(a) because both are statutory causes of action. Nevertheless, the Court found no meaningful substantive difference between the analytical frameworks for standing expressed in Lexmark and Empresa Cubana, and found that the Lexmark “zone-of-interests” proximate cause analysis and the “real interest” and “reasonable belief of damage” requirements under Empresa Cubana similarly provided a right to bring a cause of action. As such, the Court ultimately agreed with the TTAB’s conclusion that SFM’s pleaded allegations of a likelihood of consumer confusion based on a similarity of the parties’ SPROUTS and SPROUT trademarks, and their respective goods and services, were sufficient to demonstrate a reasonable belief of damage under Empresa Cubana and thus supported the right to challenge Corcamore’s registered trademark via cancellation.

With regard to the TTAB’s grant of default judgment, Corcamore did not challenge the TTAB’s express authority to grant default judgment as a sanction under 37 CFR § 2.120(h) and Fed. R. Civ. P. 37(b)(2). Instead, Corcamore argued that the TTAB had no factual or legal basis to enter default judgment in the first [...]

Size Matters in Obviousness Analysis

The US Court of Appeals for the Federal Circuit affirmed in part and reversed in part two Patent Trial and Appeal Board (Board) decisions, finding that the Board erred in its construction of certain claim terms relating to an artificial heart valve that does not require removal of the damaged native heart valve. St. Jude Medical, LLC v. Snyders Heart Valve LLC, Case Nos. 19-2108, -2109, -2140 (Fed. Cir. Oct. 15, 2020) (Taranto, J.).

St. Jude filed two petitions for inter partes review (IPR) of a patent for an artificial heart valve and a system for inserting the valve. Both petitions were instituted by the Board and resulted in final written decisions. In the first decision, the Board found that St. Jude failed to establish unpatentability of the challenged claims, rejecting St. Jude’s contention that all challenged claims were anticipated by and obvious over the Leonhardt prior art reference. In the second decision, the Board found that certain claims were anticipated by the Bessler prior art reference, but rejected St. Jude’s contentions as to all other claims. St. Jude appealed, arguing that the Board erred in the first decision by erroneously construing the term “band” and erred in the second decision by finding that St. Jude failed to prove that a skilled artisan would have made a particular combination of Bessler and the Johnson prior art. Snyders cross-appealed in the second decision as to the claims the Board found were anticipated by Bessler.

The Federal Circuit affirmed the Board’s conclusions in the first decision, finding that not only was the Board’s construction of the term “band” proper, but that it was actually broader than St. Jude’s proposed construction—and that St. Jude expressly accepted the Board’s construction. The Board construed the heart valve band to mean “a structure generally in the shape of a closed strip or ring” (replacing St. Jude’s “circular” with “closed”). In the prior art, Leonhardt discloses a graft material which extends the length of the entire structure. The Federal Circuit agreed with the Board’s finding that Leonhardt’s graft material was “like a sleeve” as opposed to “a closed strip or ring.” St. Jude argued that an ordinary skilled artisan’s understanding of the term “band” does not include a length restriction, that a Leonhardt’s material was just a long band, and that the Board effectively changed its construction of the term. The Federal Circuit, however, was not persuaded by St. Jude’s unlimited-length definition of “band,” instead turning to dictionary definitions that included terms like “thin” and “narrow,” and looking to the patent specification that did not explicitly disclaim any length restrictions. The Court ultimately rejected St. Jude’s arguments, finding that St. Jude should have proposed a claim construction that precluded any limitations on length if it wished to argue such. The Federal Circuit affirmed the Board’s findings as to first decision.

The Federal Circuit next addressed Snyder’s cross-appeal. Snyder disputed the board’s construction of the “size[] and shape[]” of a frame that the patent requires must be inserted [...]
