Antitrust Law is Not Appealing to the Federal Circuit

Posted on by

In Chandler v. Phoenix Services LLC, [2020-1848] (June 10, 2021), the Federal Circuit transferred the appeal of a Walker Process antitrust case to the Court of Appeals for the Fifth Circuit.

Appellants were asserting antitrust claims based on the attempted enforcement of U.S. Patent No. 8,171,993, which had been held unenforceable due to in-equitable conduct.

The Federal Circuit concluded that it did not have jurisdiction over the appeal. The Federal Circuit has jurisdiction over the appeal of a final decision of a district court “in any civil action arising under . . . any Act of Congress relating to patents.” 28 U.S.C. § 1295(a)(1). However, the Federal Circuit noted, “while Walker Process antitrust claims may relate to patents in the colloquial use of the term, our jurisdiction extends ‘only to those cases in which a well-pleaded com-plaint establishes either that federal patent law creates the cause of action or that the plaintiff’s right to relief necessarily depends on resolution of a substantial question of federal patent law, in that patent law is a necessary element of one of the well-pleaded claims.” Because appellant’s cause of action arises under the Sherman Act rather than under patent law, and because the claims do not depend on resolution of a substantial question of patent law, the Federal Circuit lacked subject matter jurisdiction.

The Disclaimer Doctrine Prevents Patent Owners from Construing the Claims Differently in Court than in the PTO

In Speedtrack, Inc. v. Amazon.com, Inc., [2020-1573, 2020-1660] (June 3, 2021), the Federal Circuit affirmed the district court’s final judgment of noninfringement of U.S. Patent No. 5,544,360, on a computer filing system.

At issue was the meaning of the claim term category descriptions. The district court concluded that category descriptions based on predefined hierarchical field-and-value relationships were disclaimed.

The Federal Circuit began by noting that claim terms “must be read in view of the specification.” Further, “the prosecution history can often inform the meaning of the claim language by demonstrating how the inventor understood the invention and whether the inventor limited the invention in the course of prosecution, making the claim scope narrower than it would otherwise be. The Federal Circuit said that “[a] patentee may, through a clear and unmistakable disavowal in the prosecution history, surrender certain claim scope to which he would otherwise have an exclusive right by virtue of the claim language.” Vita-Mix Corp. v. Basic Holding, Inc., 581 F.3d 1317, 1324 (Fed. Cir. 2009).

The Federal Circuit noted that during prosecution argued that the claims were not directed to a hierarchical system:

“Unlike prior art hierarchical filing systems,” the applicants explained, “the present invention does not require the 2-part hierarchical relationship between fields or attributes, and associated values for such fields or attributes.

The applicants continued: “At the most basic level, the present invention is a non-hierarchical filing system that allows essentially ‘free-form’ association of category descriptions to files without regard to rigid definitions of distinct fields containing values.”

The Federal Circuit further noted that in contrast, the applicants observed, the prior art was a hierarchical system that uses predefined field-and-value relationships.

The Federal Circuit said that “Prosecution disclaimer can arise from both claim amendments and arguments.” Tech. Props. Ltd. v. Huawei Techs. Co., 849 F.3d 1349, 1357 (Fed. Cir. 2017). In the instant case the Federal Circuit found both. The Federal Circuit that “[i]n no uncertain terms” the applicant[]s argued that the prior art had a ‘hierarchical’ relationship between fields and values that fell outside the scope of the amended claims.

The patentee argued that it distinguished the prior art on other grounds as well but the Federal Circuit said “that changes nothing.” The Federal Circuit said “[a]n applicant’s argument that a prior art reference is distinguishable on a particular ground can serve as a disclaimer of claim scope even if the applicant distinguishes the reference on other grounds as well.” Andersen Corp. v. Fiber Composites, LLC, 474 F.3d 1361, 1374 (Fed. Cir. 2007).

Ultimately, the doctrine of prosecution disclaimer ensures that claims are not construed one way in order to obtain their allowance and in a different way against accused infringers. That is what the patentee was attempting to do.

Complying with All Rules and Paying $7 Million in Fees Can Still Constitute Prosecution Laches

In Hyatt v Hirshfeld, [2018-2390, 2018-2391, 2018-2392, 2019-1038, 2019-1039, 2019-1049, 2019-1070] (June 1, 2021), the Federal Circuit vacated and remanded the district courts determination that the Patent and Trademark Office failed to prove prosecution laches, retaining jurisdiction over anticipation and written description issues.

Appellant Hyatt is the named inventor on 399 patent applications, 381 of which he filed during the “GATT Bubble” the period before the changes in law changed the term of a patent from 17 years from issuance to 20 years from filing. At issue were four of Hyatt’s applications relating to various computer technologies, and claiming priority to applications filed in the 1970s and 1980s. On October 24, 1995, about five months after Hyatt filed his GATT Bubble applications, PTO group Director Nicholas Godici met with Hyatt to discuss the applications. Director Godici asked Hyatt, and Hyatt agreed, to focus each application’s claims on distinct subject matter. As a result. Hyatt’s the number of claims in Hyatt’s application grew to 115,000, including approximately 45,000 independent claims. The four specific applications at issue included a total of 1,592 claims (an average of 398 claims per application). From 2003 to 2012, the PTO stayed the examination of many of Hyatt’s applications pending litigation. In 2013, the PTO resumed examination of Hyatt’s applications, and created an art unit, comprised originally of 12 experienced examiners dedicated to examining Hyatt’s applications.

To facilitate the examination process, from August to October 2013, the PTO issued 11 notifications to Hyatt called “Requirements,” one for each of the 11 parent applications of Hyatt’s Gatt Bubble applications. The PTO instructed Hyatt to (i) select no more than 600 total claims to pursue for each of the 11 specifications; (ii) identify the priority date and support for that date with respect to each chosen claim; and (iii) submit a clean copy of the claims. The applications were eventually finally rejected, Hyatt appealed to the PTAB, making some progress, and in 2005 initiated actions under 35 USC 145 in the U.S. District Court for the District of Columbia on some of the applications, and additional 145 actions on the remaining applications in 2009. After cross motions for summary judgement, the USPTO filed motions to dismiss for prosecution laches. The PTO argued that Hyatt had engaged in a “pattern of delay in prosecuting his nearly 400 patent applications from 1969 through the present day — even disregarding the 9 years when the USPTO stayed Hyatt’s applications.

The PTO argued that Hyatt forfeited his patent rights by, for example, claiming priority to ap-plications more than 45 years old; bulk-filing about 400 photocopies of 11 applications in the days before the U.S.’s patent term changed on June 8, 1995; and agreeing to focus each application on a different invention but not doing so and later revealing that he never had a “master plan” for demarcating the applications.

Hyatt responded that his prosecution of applications other than the four at issue was legally irrelevant; that the PTO itself engaged in extensive delays in administering his applications; that the PTO did not warn him, as allegedly required, that he was in jeopardy of losing his patent rights; and that the PTO failed to prove intervening rights as necessary to establish prosecution laches. Hyatt also argued that his delays were explainable be-cause, for example, PTO rules permitted Hyatt to add and amend claims, and Hyatt did so to correctly capture his inventions and steer clear of prior art.

The Prosecution laches defense originates from two Supreme Court cases: In Woodbridge v. United States, 263 U.S. 50 (1923), the PTO agreed with Woodbridge’s request to delay the issuance of his patent for one year, but at the end of the year, the PTO neglected to issue the patent. Woodbridge waited an additional eight-and-a-half years before sending a letter to the PTO calling attention to the application and explaining that he had waited because the delay enabled him to best avail himself of the patent’s value. Woodbridge then sought to amend the specification and claims to capture related innovations that arose during the course of the delay. The Court held that, by delaying to make the term of the monopoly square with the period when the commercial profit from it would have been highest, Woodbridge forfeited the right to a patent by designed delay. The Court said:

[a]ny practice by the inventor and applicant for a patent through which he deliberately and without excuse postpones beyond the date of the actual invention, the beginning of the term of his monopoly, and thus puts off the free public enjoyment of the useful invention, is an evasion of the statute and defeats its benevolent aim.

In Webster Elec. Co. v. Splitdorf Elec. Co., 264 U.S. 463 (1924), the applicant filed a patent application in 1910. In 1915, to provoke an interference against a separate, recently issued patent, the applicant filed a divisional application copying the patent’s claims. The applicant lost the interference but then amended the divisional application by adding two new claims, claims 7 and 8, which issued in 1918 and were the subject of the litigation. The Court held claims 7 and 8 unenforceable, noting it had “no hesitation in saying that the delay was unreasonable, and, under the circumstances shown by the record, constitutes laches, by which the petitioner lost whatever rights it might other-wise have been entitled to.”

The Federal Circuit recognized the doctrine of prosecution laches in Symbol Techs., 277 F.3d at 1363, 1366–68, and applied it for the first time in In re Bogese, 303 F.3d 1362, 1363 (Fed. Cir. 2002), where the patent owner had engaged in “deliberate and consistent course of conduct that has resulted in an exceptional delay in advancing the prosecution and the issuance of a patent,” filing twelve continuation applications without amendment or addressing the reasons for the rejection and each time abandoned the previous application.

The Federal Circuit concluded that the district court misapplied the legal standard for prosecution laches in several respects. First, the Federal Circuit said that the district court failed to properly consider the totality of the circumstances. The district court stated that the totality principle does not apply in a manner as to require this Court to account for the entirety of the prosecution history of each related application from its inception to final disposition. In addition, the district court then focused predominantly on the PTO’s role in the prosecution of Hyatt’s four applications at issue and repeatedly discounted or ignored evidence showing that Hyatt’s conduct caused unreasonable and unexplained delay.

Second the Federal Circuit said that rather than analyze the evidence to determine whether Hyatt’s conduct warrants a finding of prosecution laches, the court repeatedly placed blame on the PTO for the slowness with which Hyatt’s applications were prosecuted. The Federal Circuit has said that “a delay by the PTO cannot excuse the appellant’s own delay. The Federal Circuit concluded that the district court erred by improperly focusing the analysis on the PTO’s conduct rather than Hyatt’s conduct.

The Federal Circuit concluded that the PTO’s prosecution laches evidence and arguments presented at trial are enough to shift the burden to Hyatt. Beyond merely the magnitude of Hyatt’s delay in filing his claims, The Federal Circuit found that Hyatt adopted an approach to prosecution that all but guaranteed indefinite prosecution delay. The Federal Circuit thus remanded the case to the district court for the limited purpose of affording Hyatt the opportunity to present evidence on the issue of prosecution laches, consistent with the standards set forth in this opinion.

The Federal Circuit added that to carry his burden, Hyatt must show by preponderance of evidence that Hyatt had a legitimate, affirmative reason for his delay, and quipped that it could “divine no reason in the record currently before the court that would suffice, but Hyatt is entitled as a matter of fairness to present evidence and be heard on this issue.”

The References are not the Only Sources a Person of Ordinary Skill Would Consider

In Becton, Dickinson and Company v. Baxter Corporation Englewood, [2020-1937] (May 28, 2021), the Federal Circuit reversed that PTAB determination that certain claims of U.S. Patent No. 8,554,579 were not invalid as obvious. The’579 Patent is directed to systems for preparing patient-specific doses and a telepharmacy method in which data captured while following a protocol associated with each received drug order and specifying a set of steps to fill the drug order are provided to a remote site for review and approval by a pharmacist.

At issue was whether the art disclosed a verification step. Baxter successfully argued to the PTAB that the art taught that there may be a verification step, but not that there must be a verification step. The Federal Circuit concluded that the Board’s determination was not supported by substantial evidence. The Federal Circuit said that in the context of the prior art, “may” does not mean “occasionally,” but rather that one “may” choose to systematically check each step. Examining the reference, the Federal Circuit concluded that the purpose was to provide verification, and thus it satisfied the verification step.

Also at issue was whether the art diclosed the highlighting limitation, which requires “an interactive screen that includes prompts that can be highlighted by an operator to receive additional information relative to one particular step.” The Federal Circuit found that one of the references teaches highlighting in the pharmacy context, and said that the Board erred in looking to the reference as the only source a person of ordinary skill would consider for what “additional information might be relevant. A person of ordinary skill is also a person of ordinary creativity, not an automaton.

Finally, the Federal Circuit said that Baxter does not meaningfully argue that the weak showing of secondary considerations here could overcome the showing of obviousness based on the prior art.

Don’t Forget to Claim What the Device Is, Not Just What the Device Does

In Bio-Rad Laboratories, Inc. v. ITC, [2020-1475, 2020-1605] (May 28, 2021), the Federal Circuit affirmed the Com-mission’s determination that 10X did not infringe the claims of U.S. Patent No. 9,500,664, and that 10X infringed the claims of U.S. Patent Nos. 9,636,682 and 9,649,635.

The relate generally to the field of microfluidics, and specifically to the generation of microscopic droplets, and in particular to systems and methods for generating microscopic droplets by using a micro-fluidic device commonly referred to as a “chip.”

Regarding the ‘664 patent, the ALJ determined that because the accused Chip GB does not involve a “sample,” it “does not include a ‘sample well,’ a sample channel, sample-containing droplets, or the claimed ‘droplet generation region.’” The Federal Circuit found that the patent distinguished between samples and reagents, and that the accused product was used with reagents and not samples as required by the claims. 10X and the ITC argued that the ALJ applied the exact construction of “sample” to which the parties agreed, and that Bio-Rad’s challenge is really directed at the ALJ’s factual application of that construction to the accused Chip GB, which the Federal Circuit found was supported by substantial evidence.

Bio-Rad also contended that, regardless whether the monomer solution in the accused Chip GB is a “sample,” the claims recite structural limitations all of which are included in the accused Chip GB. The Federal Circuit rejected the argument for several reasons. First, it was not clear that Bio-Rad raised this argument before the Commission. Second, the argument is premised on rewriting the claims in an oversimplified form and removing all limitations that differentiate the recited structures from each other. The Federal Circuit noted that the inventors did not seek patent protection for a broad claim to “a chip with three wells and interconnecting channels.” Nor did the inventors choose to differentiate the wells and channels from each other based on physical characteristics (e.g., shape, size, depth, location, etc.). Instead, the inventors chose to characterize the wells and channels based on the material contained within them. “Bio-Rad cannot escape that choice by pointing to the general proposition of law that “apparatus claims cover what a device is, not what a device does.”

With respect to the appeal of the finding infringement of the ‘682 and ‘635 patents, 10X argued error with respect to the ITC construction of “droplet-generation region.” However, the Federal Circuit found that the ALJ’s construction of the term “droplet-generation region” was consistent with the intrinsic evidence, and like the ITC, the Federal Circuit rejected 10X’s attempt to impose an unclaimed limitation that requires a channel to extend directly from the sample well to the droplet-generation region. The Federal Circuit found that under the ALJ’s correct construction, substantial evidence supported the Commission’s finding that the use of 10X’s accused chips directly infringes the asserted claims of the ’664, ’682, and ’635 patents.

On the issues of contributory infringement and inducement of infringement, the Federal Circuit concluded there was substantial evidence to support the ALJ’s findings.

Applying Vitiation to “Annular Cover” was Circular Reasoning

In Edgewell Personal Care Brands, LLC v. Munchkin, Inc., [2020-1203] (May 26, 2021 modifying March 9, 2021, opinion), the Federal Circuit vacated-in-part, reversed-in-part, and remanded the district court’s summary judgement of no infringement of U.S. Patent Nos. 8,899,420 and 6,974,029 on Diaper Genie refills.

The claims of the ‘420 patent were directed to a cassette intended for use in the Diaper Genie.  The Federal Circuit noted that a cassette has a clearance that will ensure proper insertion whether a space remains after insertion or not. We thus conclude that the district court erred by adding this limitation into its construction. The clearance limitation is satisfied when the cassette itself is constructed with a clearance. The claim does not require a clearance after insertion; in fact, such a requirement would be at odds with many of the disclosed embodiments and is simply not required by the claims. The Federal Circuit reasoned: “The clearance limitation is satisfied when the cassette itself is constructed with a clearance. The claim does not require a clearance after insertion; in fact, such a requirement would be at odds with many of the disclosed embodiments and is simply not required by the claims.”

With respect to the claims of the ‘029 patent, the Federal Circuit found that although the district court correctly construed “annular cover” as being a single structure, the district court erred in concluding that Edgewell’s theory of infringement under the doctrine of equivalents vitiates or renders meaningless the “annular cover” claim element. The Federal Circuit explained that vitiation has its clearest application where the accused device contains the antithesis of the claimed structure.  But warned that, as it explained in Deere & Co. courts should be cautious not to shortcut this inquiry by identifying a ‘binary’ choice in which an element is either present or not present.  The determination of equivalence depends not on labels like ‘vitiation’ and ‘antithesis’ but on the proper assessment of the language of the claimed limitation and the substantiality of whatever relevant differences may exist in the accused structure.”). Applying these concepts to the facts of this case, the Federal Circuit concluded that the district court erred in evaluating the element as a binary choice between a single-component structure and a multi-component structure, rather than evaluating the evidence to determine whether a reasonable juror could find that the accused products perform substantially the same function, in substantially the same way, achieving substantially the same result as the claims. Because the district court based its grant of summary judgment of noninfringement of the ’420 patent on an erroneous construction, the Federal Circuit vacated that judgment and remanded. Because the district court erred in granting Munchkin summary judgment of noninfringement of the ’029 patent, the Federal Circuit reversed that judgment and remanded

Federal Circuit Ignores Forum Selction Clause Allowing IPR to Proceed

In New Vision Gaming & Development, Inc., v. SG Gaming, Inc., [2020-1399, 2020-1400](May 13, 2021) the Federal Circuit vacated PTAB decisions that U.S. Patent Nos. 7,451,987 and 7,325,806, as well as proposed substitute claims, are patent ineligible under 35 U.S.C. § 101, and remanded the case for further proceedings consistent with Arthrex.  The Federal Circuit said that because Arthrex issued after the Board’s final-written decisions and after New Vision sought Board rehearing, New Vision had not waived its Arthrex challenge by raising it for the first time in its opening brief before the Court.

.

Judge Newman agreed that Arthrex applied but dissented because the Court did not address the forum selection clause in the license between the parties.  The parties agreed that “any dispute between any of the parties that cannot be resolved amicably” should be resolved in the state and federal courts in the State of Nevada, and thus Judge Newman argued that the forum question requires resolution, for if the parties are committed to a Nevada forum instead of the PTAB, there is no basis for new PTAB proceedings on remand.

Thus, while I Judge Newman agreed that the Board’s decision must be vacated under Arthrex, she respectfully dissented from remand without resolving the issue of forum selection.

A Cease and Desist Letter Can Confer Personal Jurisdiction

Posted on by

In Trimble Inc., Innovative Software Engineering, LLC, v. Perdiemco LLC, [2019-2164] (May 12, 2021), the Federal reversed the dismissal of Trimble’s declaratory judgment noninfringement action against PerDiemCo LLC for lack of personal jurisdiction.

Base upon Red Wing Shoe Co. v. Hockerson-Halberstadt, Inc., 148 F.3d 1355 (Fed. Cir. 1998), the United States District Court for the Northern District of California held that it would be unreasonable to assert personal jurisdiction over PerDiemCo based on its communications to Trimble in California. However the Federal Circuit concluded that Red Wing does not preclude personal jurisdiction on the facts of this case and that the district court had personal jurisdiction over PerDiemCo.

PerDiemCo’s current sole owner, officer, and employee is Robert Babayi. He lives and works in Washington, D.C. PerDiemCo rents office space in Marshall, Texas. Mr. Babayi has never visited the rented space, and PerDiemCo has no employees in Marshall.  In October 2018, Mr. Babayi, on behalf of PerDiemCo, sent a letter to ISE in Iowa accusing ISE’s products and services of using technology covered by at least PerDiemCo’s electronic-logging-device patents. The letter also explained that PerDiemCo actively licences its patents and listed at least ten companies that had entered into nonexclusive licenses after the companies had “collectively spent tens of millions of dollars in litigation expenses.” Attached to PerDiemCo’s letter was an unfiled complaint for the Northern District of Iowa, which asserted nine of PerDiemCo’s patents against ISE’s products and services, and a claim chart that provided further detail re-garding the alleged infringement. The letter also offered ISE a nonexclusive license to PerDiemCo’s patents, proposed that the parties engage in negotiations, and attached a draft nondisclosure agreement to facilitate the parties’ discussions.  The parties entered negotiations, during which PerDiemCo communicated with Trimble via letter, email, or telephone at least twenty-two times.  In this correspondence and telephone calls, PerDiemCo threatened to sue Trimble for patent infringement in the Eastern District of Texas and identified counsel that it had retained for this purpose.

In Red Wing Shoe Co. v. Hockerson-Halberstadt, Inc., 148 F.3d 1355 (Fed. Cir. 1998), the Federal Circuit states that a patentee should not subject itself to personal jurisdiction in a forum solely by informing a party who happens to be located there of suspected infringement because grounding personal jurisdiction on such contacts alone would not comport with principles of fairness,  The Fedeal Circuit noted three subsequent developments that have clarified the scope of Red Wing.

First, the Supreme Court cases following Red Wing have made clear that the analysis of personal jurisdiction cannot rest on special patent policies.  Second, the Supreme Court has held that communications sent into a state may create specific personal jurisdiction, depending on the nature and scope of such communications.  Third, the Supreme Court’s recent decision in Ford has established that a broad set of a defendant’s contacts with a forum are relevant to the minimum contacts analysis.

Given these developments and consistent with the Supreme Court’s instruction to treat “isolated or sporadic [contacts] differently from continuous ones,” the Federal Circuit concluded that Red Wing remains correctly decided with respect to the limited number of communications involved in that case. However, there is no general rule that demand letters can never create specific personal jurisdiction. The Federal Circuit said the central question under Red Wing is now whether a defendant’s connection to a forum is sufficient to satisfy the minimum contacts or purposeful availment test and, whether the exercise of jurisdiction con-forms to the due process and fairness criteria of precedent.  The Federal Circuit concluded that the minimum contacts or purposeful availment test was satisfied

The Federal Circuit said that PerDiemCo thus has not made a compelling case that the presence of some other considerations would render jurisdiction unreasonable, and it reversed the district court’s order finding a lack of personal jurisdiction and remanded for further proceedings.

Intrinsic Evidence > Dictionary Definitions, Analogies, and Purported Plain Meaning

 In Uniloc 2017 LLC v. Apple Inc., [2020-1403, 2020-1404] (May 12, 2021), the Federal Circuit affirmed the PTAB determination that claims 1–17 and 23–25 of  U.S. Patent No. 8,539,552 were invalid for obviousness.

The ’552 patent is directed to a system and method to police the use of various optional features, such as caller-ID, call waiting, multi-line service, and different levels of service quality known as the “codec specification.”

On appeal, Uniloc contended that the Board’s construction of “intercepting” in the independent claims was erroneous and that the Board incorrectly held claims 1–17 and 23–25 invalid as a result. In its cross-appeal, Apple argued that the Board erroneously rejected its challenge to claims 18–22.

As to Unilock’s appeal the Federal Circuit noted that because the receiving client device is the ultimate “intended recipient” does not mean that the sending client device cannot intentionally direct the message to the intercepting entity.  The Federal Circuit held that the claims encompass the situation in which a sending client device intentionally sends a signaling message to the intermediate network entity that per-forms the interception. Contrary to Uniloc’s contention, the Federal Circuit said that construction is not at odds with the plain meaning of the claims. The receiving client device is still “the intended recipient” of the message because it is the ultimate, in-tended destination of that message.  The Federal Circuit further further noted that the Board’s construction is supported by the prosecution history. The Federal Circuit said it arrived at its construction by focusing on the prosecution history, the specification, and the context of the particular claims in which the term “intercepting” appears, which outweighed Uniloc’s reliance on dictionary definitions, analogies, and the purported plain meaning of “intercepting” in isolation.
