A Goldilocks Dilemma: What is the “Right Amount” When Pleading Patent Infringement Cases?

Addressing the issue of pleading requirements for patent infringement cases, the US Court of Appeals for the Federal Circuit clarified that patentees need not prove their case at the pleading stage on an element-by-element basis but can plead themselves out of court by presenting facts that are inconsistent with their infringement claims. Bot M8 LLC v. Sony Corp. of Am., Case No. 20-2218 (Fed. Cir. July 13, 2021) (O’Malley, J.)

Bot M8 filed suit against Sony and alleged that Sony’s PlayStation 4 and PlayStation network infringed Bot M8’s asserted patents, which are all generally directed to casino, arcade and video games. The asserted patents describe an “authentication mechanism to verify that a game program has not been manipulated,” a “gaming machine [that stores] gaming information and a mutual authentication program on the same medium,” a “gaming device with a fault inspection system,” and a “gaming machine that changes future game conditions based on players’ prior game results.”

The district court sua sponte instructed Bot M8 to file an amended complaint, “specifying ‘every element of every claim that [Bot M8] say[s] is infringed’” and to reverse engineer Sony’s products to prove its case. Bot M8 did not challenge the district court’s order and agreed to file claim charts. Following Bot M8’s service of the first amended complaint, Sony filed a motion to dismiss, which the district court granted. On an unrelated patent, both parties filed summary judgment motions. The district court entered final judgment in favor of Sony, and Bot M8 subsequently appealed both the dismissals and the grant of summary judgment.

On appeal, the Federal Circuit emphasized that “patentees need not prove their case at the pleading stage” and thus found that the district court had erred by misapplying Iqbal and Twombly. Apparently exasperated by the need to reiterate the proper pleading standard, the Court emphasized that “[a] plaintiff is not required to plead infringement on an element-by-element basis.”

While reaffirming a standard favorable to patentees, the Federal Circuit explained that for a complaint to pass muster under Iqbal and Twombly, it still must provide sufficient factual allegations to “articulate why it is plausible that the accused product infringes the patent claim.” Thus, “a patentee may subject its claims to early dismissal by pleading facts that are inconsistent with the requirements of its claims.” The Court explained that Bot M8’s allegations conflicted with claim 1 of Bot M8’s patent. Whereas that claim required a motherboard separate from the authentication and game programs, Bot M8’s claim charts expressly alleged that “[t]he authentication program for the PlayStation 4 hard drive, operating system, and games is stored on PlayStation 4 . . . Serial Flash Memory” and that “[t]he PlayStation 4 motherboard contains flash memory.” According to the Court, it was “not even possible, much less plausible” for Bot M8 to prevail because of this inconsistency between Bot M8’s allegations and its patent with respect to the location of the authentication and game programs relative to the motherboard. By pleading “too much rather [...]

Venue Manipulation Obviates Geographically Bounded Claims in Venue Analysis

The US Court of Appeals for the Federal Circuit issued a rare grant of two mandamus petitions directing the US District Court for the Western District of Texas to transfer the underlying patent infringement actions to the US District Court for the Northern District of California pursuant to 28 U.S.C. § 1404(a). In re: Samsung Elecs. Co., Ltd., Case Nos. 21-139, -140 (Fed. Cir. June 30, 2021) (Dyk, J.)

Ikorongo Technology owned four patents directed to functionalities allegedly performed by applications run on the accused mobile products sold by Samsung and LG. Ikorongo Technology assigned to Ikorongo Texas—an entity formed only weeks before—exclusive rights to sue for infringement of those patents within specified parts of the state of Texas, including certain counties in the Western District of Texas, while retaining the rights to the patents in the rest of the United States.

Ten days later, Ikorongo Texas sued Samsung and LG in the Western District of Texas. Although Ikorongo Texas claimed to be unrelated to Ikorongo Technology, the operative complaints indicated that the same five individuals owned both Ikorongo Texas and Ikorongo Technology, and that both entities shared office space in North Carolina.

The day after filing the initial complaints, Ikorongo Texas and Ikorongo Technology filed first amended complaints, this time naming both Ikorongo Technology and Ikorongo Texas as co-plaintiffs, noting that together Ikorongo Texas and Ikorongo Technology owned the entire right, title and interest in the asserted patents, including the right to sue for past, present and future damages throughout the United States and the world.

Samsung and LG separately moved under 28 U.S.C. § 1404(a) to transfer the suits to the Northern District of California, arguing that “three of the five accused third-party applications were developed in Northern California, where those third parties conduct significant business activities and no application was developed or researched in Western Texas.” Samsung and LG also argued that potential witnesses and sources of proof were located in the Northern District of California.

The district court first concluded that Samsung and LG failed to establish § 1404(a)’s threshold requirement that the complaints “might have been brought” in the Northern District of California. Because Ikorongo Texas’s rights under the asserted patents were limited to the state of Texas and could not have been infringed in the Northern District of California, the district court held that venue over the entirety of the actions was improper under § 1400(b), which governs venue in patent infringement cases. Alternatively, the district court analyzed the traditional public- and private-interest factors, finding that defendants had not met their burden to show cause for transfer. Samsung filed for mandamus to the Federal Circuit.

The Federal Circuit found that the district court erroneously disregarded Ikorongo Technology and Ikorongo Texas’s attempts to manipulate venue when analyzing venue under § 1404(b). While no act of infringement of Ikorongo Texas’s geographically bounded rights took place in the Northern District of California, the Federal Circuit determined that “the presence of Ikorongo Texas is plainly recent, ephemeral, and [...]

Diehr Alice, Yu are Superimposing Novelty onto Patent Eligibility. Love, Newman.

The US Court of Appeals for the Federal Circuit affirmed the district court’s grant of a Rule 12(b)(6) motion to dismiss on the basis that, under the two-step Alice analysis, the patent claims—directed to a digital camera—were directed to ineligible subject matter under 35 U.S.C. § 101. Yu, et al. v. Apple Inc., et al., Case Nos. 20-1760; -1803 (Fed. Cir. June 11, 2021) (Prost, J.) (Newman, J., dissenting)

The patent claim under consideration recited an “improved digital camera” that has two lenses, two image sensors, an analog-to-digital converter, a memory and a digital image processor for “producing a resultant digital image from said first digital image enhanced with said second digital image.” Yu conceded that “the idea and practice of using multiple pictures to enhance each other has been known by photographers for over a century” and that the components recited in the claim “are themselves generic and conventional.”

Applying the Supreme Court’s two-step Alice v. CLS Bank test for determining patent eligible subject matter, the Federal Circuit determined at step one that the claim was “directed to the abstract idea of taking two pictures . . . and using one picture to enhance the other in some way.” At step two, the Court held that the claim failed to otherwise define a patent eligible invention because the digital camera “is recited at a high level of generality and merely invokes well-understood, routine, conventional components to apply the abstract idea of [using one picture to enhance the other in some way].” The Court rejected Yu’s attempts to use portions of the patent’s specification to support eligibility, explaining that the eligibility analysis is limited to the literal recitations of the asserted claims.

Then, along came Judge Pauline Newman. With a chainsaw.

In dissent, Judge Newman argued that the majority was improperly enlarging the § 101 analysis to include other “substantive requirements of patentability.” Judge Newman emphasized (twice) that the claim literally recited an electromechanical camera, not an abstract idea. In her view, the camera recited in the claim met the requirements of § 101 as a new and useful machine, without regard to whether the claimed camera also met the novelty requirements of §§ 102 and 103. Referring to the Supreme Court’s 1981 holding in Diamond v. Diehr, Judge Newman wrote that “[i]n contravention of [Diehr‘s] explicit distinction between Section 101 and Section 102, the majority now holds that the [claimed] camera is an abstract idea because the camera’s components were well-known and conventional and perform only their basic functions.” Judge Newman further proclaimed that “the principle that the majority today invokes was long ago discarded.”

Judge Newman also admonished the majority for the destabilizing effects that similar holdings have already had on US patent policy. She noted that “[i]n the current state of Section 101 jurisprudence, inconsistency and unpredictability of adjudication have destabilized technologic development in important fields of commerce,” and that “[t]he fresh uncertainties engendered by the majority’s revision of Section 101 are contrary to the statute and [...]

Federal Circuit Lacks Appellate Jurisdiction over Standalone Walker Process Claims

The US Court of Appeals for the Federal Circuit ordered the transfer of a case asserting standalone Walker Process antitrust claims involving an unenforceable patent to the regional circuit, in this case the US Court of Appeals for the Fifth Circuit. Chandler v. Phoenix Services LLC, Case No. 20-1848 (Fed Cir. June 10, 2021) (Hughes, J.) The case originated in the US District Court for the Northern District of Texas, over which the Fifth Circuit has appellate jurisdiction. The decision to transfer was based on a subject matter jurisdiction analysis for Walker Process claims. The Federal Circuit reiterated that its precedent does not mandate exclusive Federal Circuit jurisdiction over all Walker Process cases.

In 2006, Phoenix Services and Mark Fisher (collectively, Phoenix) acquired a company called Heat On-The-Fly and its patent to protect a purported proprietary fracking process. Heat-On-The-Fly, and later Phoenix, sought to enforce the patent against numerous parties. During the patent application process, however, Heat On-The-Fly had failed to disclose numerous public uses of the fracking process prior to the application filing. In 2018, in an unrelated case, Energy Heating, LLC v. Heat On-The-Fly, the Federal Circuit, held that “failure to disclose prior uses of the fracking process rendered the . . . patent unenforceable due to inequitable conduct.” The plaintiffs in the case at hand, Ronald Chandler, Chandler MFG., Newco Enterprises and Supertherm Heating Services (collectively, Chandler), alleged that Phoenix’s continued enforcement of the patent violated Walker Process pursuant to § 2 of the Sherman Act.

Walker Process monopolization claims originate from a 1965 Supreme Court decision that recognized an antitrust cause of action under the Sherman and Clayton Acts when a party fraudulently obtains a patent for the purpose of attempted monopolization. Walker Process Equipment, Inc. v. Food Machinery & Chemical Corp. To succeed on a Walker Process claim, a plaintiff must satisfy two elements:

  • The plaintiff must show that the defendant obtained the patent through knowing and willful fraud on the US Patent & Trademark Office and enforced that patent with knowledge of its fraudulent procurement.
  • The plaintiff must be able to satisfy all other elements for a Sherman Act monopolization claim.

Pursuant to 28 U.S.C. § 1295(a)(1), the Federal Circuit retains jurisdiction over any civil case arising under any act of Congress relating to patents. In this instance, the Federal Circuit stated that Walker Process antitrust claims may relate to patents “in the colloquial use of the term,” but under 1988 Supreme Court precedent, Christianson v. Colt Indus., the Federal Circuit’s jurisdiction only extends to cases where the cause of action is created under federal patent law, or where the plaintiff’s right to relief “necessarily depends on resolution of a substantial question of federal patent law.”

Here, the Federal Circuit relied on its own 2018 precedent where it analyzed subject matter jurisdiction for Walker Process claims. Xitronix Corp v. KLA-Tencor Corp. (Xitronix I). Xitronix I involved alleged fraud by the defendants to obtain a patent. The Court acknowledged [...]

What You Say Can and Will be Used Against You – Prosecution History and Prior Infringement Arguments

Noting patent owner’s prior litigation statements, the US Court of Appeals for the Federal Circuit upheld a district court ruling that a clear and unmistakable disclaimer in the prosecution history affected claim construction of an asserted patent. SpeedTrack, Inc. v. Amazon.com, Inc., Case No. 20-1573 (Fed. Cir. June 3, 2021) (Prost, J.)

In 2009, SpeedTrack filed suit against various online retailers alleging infringement of its patent directed to a method for accessing files in a filing system leveraging “category descriptions” to aid in organizing the files. The patent describes associating category descriptions with files using a “file information directory.” A “search filter” then searches the files using their associated category descriptions. A limitation that “the category descriptions hav[e] no predefined hierarchical relationship with such list or each other” was added during prosecution to overcome a prior art reference that leveraged hierarchical field-and-value relationships.

The district court initially adopted a proposed claim construction that lacked any reference to a field-and-value relationship, noting that the construction “account[ed] for the disclaimers made during prosecution.” Following a motion by SpeedTrack, the court concluded there was still a fundamental dispute about the scope of the claim term. After further analyzing SpeedTrack’s prosecution history, the court concluded that the history “demonstrate[d] clear and unambiguous disavowal of category descriptions based on hierarchical field-and-value systems” and issued a second claim construction order explicitly disclaiming “predefined hierarchical field-and-value relationships” from the scope of “category descriptions.” SpeedTrack subsequently stipulated to noninfringement under the second claim construction and appealed.

On appeal, the Federal Circuit stressed that prosecution-history disclaimer can arise from both claim amendments and arguments. Here, the prosecution history showed that the applicants “repeatedly highlighted predefined hierarchical field-and-value relationships” as a difference between the prior art and the patent claims in no uncertain terms. That SpeedTrack distinguished the prior art on other grounds did not moot its disclaimer statements.

The Federal Circuit also noted that SpeedTrack argued in litigation against another defendant that the purpose of the amendment was to distinguish the category descriptions from attributes that “have a ‘hierarchical’ relationship between fields and their values.” While the Court agreed with SpeedTrack that such litigation statements were not a disclaimer on their own (since they were not the inventors’ prosecution statements), these litigation statements further supported not accepting SpeedTrack’s arguments. The Court reminded SpeedTrack that it has cautioned (in Aylus and Southwall) that “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.’”

After assessing SpeedTrack’s prior statements, the Federal Circuit considered whether the disclaimer was clear and unmistakable. The Court concluded it was. In rejecting SpeedTrack’s argument that prior decisions not expressly finding disclaimer supported that prosecution statements were not clear and unambiguous, the Court noted the construction had not been fully considered in those judgments. Similarly, the Court rejected the notion that the district court’s issuance of a second claim construction order showed there was no clear and [...]

Submarine Sunk: Patent Prosecution Laches Pops GATT Bubble

Addressing for the first time whether the US Patent & Trademark Office (PTO) can assert prosecution laches as a defense in a civil action brought under 35 U.S.C. §145, the US Court of Appeals for the Federal Circuit held that the PTO could assert prosecution laches as a defense against four patent applications in a case where the plaintiff delayed presenting the claims for these applications over a period of at least 10 years. Hyatt v. Hirshfeld, Case Nos. 2018-2390; -2391; -2392; 2019-1038; -1039; -1049; -1070 (Fed. Cir. June 1, 2021) (Reyna, J.)

Gilbert Hyatt is well known for having built a prolific patent application portfolio based on nearly 400 initial filings made just before the United States changed from an issuance-based patent exclusivity system to a filing-based patent exclusivity system under the Uruguay Round of the General Agreement on Tariffs and Trade (GATT). By 2003, those 400 initial filings had exploded into 45,000 independent claims. Hyatt’s applications were so labor intensive that the PTO developed a separate examining unit specifically dedicated to their review. Many of these applications have been rejected.

After the PTO finally rejected four of Hyatt’s computer software patent applications, in 2005 Hyatt filed a § 145 action in the district court. Throughout the litigation, the PTO argued that Hyatt had routinely delayed prosecuting his patent applications and never complied with his verbal agreement with the PTO to streamline each application to apply for only one invention. Ultimately, after a five-day bench trial, the district court found that the PTO failed to prove it had taken sufficient action to advance prosecution of Hyatt’s applications. The PTO appealed.

Resolving the threshold issue on appeal of whether prosecution laches is even available to the PTO in a § 145 action, the Federal Circuit explained that the right to assert laches as an affirmative defense flows naturally from the PTO’s rights to reject applications based on laches and defend such rejections on appeal in the Federal Circuit on the same grounds. Any other conclusion, the Court recognized, would create incongruence and undermine the PTO’s authority. Such a defense is available even if raised for the first time in the district court, as “§145 actions open the door to new evidence.”

The Court found significant errors in the district court’s application of prosecution laches law. First, the Federal Circuit held that the district court too narrowly focused on the PTO’s specific conduct without considering the totality of the circumstances, including delays caused by Hyatt’s sweeping amendments and prosecution of other patent applications, as well as the relative costs and burdens of examining Hyatt’s gargantuan application portfolio. The Court was particularly critical regarding the district court’s assignment of blame to the PTO in its attempts to manage the unwieldy task before it.

After reviewing the evidence presented by the PTO, the Federal Circuit found that the PTO had amassed significant evidence of Hyatt’s delay of prosecution of his applications—i.e., “patterns of prosecution conduct [that] created a perfect storm that overwhelmed the [...]

It’s Highlighted and Verified: Reversal of PTAB Non-Obviousness Decision

In a relatively unusual outcome, the US Court of Appeals for the Federal Circuit reversed a Patent Trial & Appeal Board (Board) decision finding non-obviousness in an inter partes review (IPR). Becton, Dickinson, and Co. v. Baxter Corp. Englewood, Case No. 20-1937 (Fed. Cir. May 28, 2021) (Dyk, J.)

Becton petitioned the Board for IPR of Baxter’s pre-America Invents Act (AIA) patent, directed to a system for preparing patient-specific doses and a method for telepharmacy. The Board decided that the patent claims were not shown to be invalid as obvious, but also found that Baxter’s secondary considerations evidence was “weak.” Becton appealed based on two contested limitations: a verification limitation and a highlighting limitation. The Federal Circuit reversed the Board, concluding that the challenged claims were obvious and explained that weak evidence of secondary considerations could not overcome the strong showing of obviousness.

First, the Federal Circuit decided that the Board erred in finding that a prior art reference that taught a remote pharmacist may verify a dose preparation did not render obvious a claimed method where a remote pharmacist must verify. The reference made clear that a non-pharmacist could not further process work without the verification step. Baxter’s own expert witness conceded that, in accordance with the teachings of the prior art, a non-pharmacist would be disciplined for continuing to process dose preparation without authorization. The Court concluded there was no significant difference between the teaching in the prior art reference and Baxter’s verification requirement.

Second, the Federal Circuit decided that the Board erred in finding that the “highlighting” limitation as it relates to a set of drug preparation steps on a computer was non-obvious. In what it characterized as a “close case,” the Board decided that a prior art reference’s teachings highlighting patient characteristics when dispensing repackaged medication did not make obvious highlighting, in a drug formulation context, prompts for additional information. Citing KSR v. Teleflex, the Court explained that the “combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” The reference taught highlighting in terms of various inputs and information delivered. Becton’s expert testified that one of ordinary skill would understand from the reference that other information, such as prescription order information, could be displayed on the user interface. Baxter’s expert did not contradict Becton’s expert. Because “a person of ordinary skill is also a person of ordinary creativity, not an automaton,” the Board erred in using that one reference as the only source for what one of ordinary skill would consider.

Lastly, Baxter unsuccessfully argued that under pre-AIA 35 U.S.C. § 102(e)(2), one of the patent references was ineligible as prior art. Sec. 102(e)(2) provides that a prior art reference may be a “patent granted” on another’s application filed in the United States before the invention by the applicant. Baxter argued that since the claims of the reference were cancelled after a 2018 IPR, the reference no longer qualified as a “patent granted” [...]

Not With a Bang but a Whimper

In a non-precedential Order issued by the US Court of Appeals for the Federal Circuit—on remand from the US Supreme Court’s April 2021 decision upholding Google’s fair use defense to Oracle’s copyright infringement claim—the Court recalled its mandate in the case “solely with respect to fair use,” leaving intact the Federal Circuit’s May 2014 judgment favoring Oracle on the question of copyrightability. Oracle America Inc. v. Google LLC, Case Nos. 17-1118; 1202 (Fed. Cir. May 14, 2021)(PER CURIAM). After recalling its mandate, the Federal Circuit issued its order without further briefing by the parties.

New Perspective on Specific Personal Jurisdiction in Patent DJ Venue

The US Court of Appeals for the Federal Circuit concluded that the minimum contacts or purposeful availment test for specific personal jurisdiction was satisfied where a patent owner sent multiple infringement notice letters and other communications to a resident of California who then filed for declaratory judgment of non-infringement in federal district court in California. Trimble Inc. v. PerDiemCo LLC, Case No. 19-2164 (Fed. Cir. May 12, 2021) (Dyk, J.)

PerDiem accused Trimble of infringing several of PerDiem’s patents. PerDiem exchanged 22 communications with Trimble in California over a period of three months, some through Trimble’s subsidiary ISE in Iowa and other communications through its chief IP counsel in Colorado. The communications started with a letter (sent to ISE in Iowa) that had attached an unfiled complaint and which PerDiem used to try to launch license negotiations. This unfiled complaint asserted nine of PerDiem’s patents. After ISE brought Trimble, its parent, into the discussion, PerDiem accused Trimble’s products of infringing 11 patents and sought to enter into binding mediation on its infringement allegations. PerDiem also threatened to sue Trimble in the Eastern District of Texas and identified the counsel it planned to use for this purpose. Trimble filed for a declaratory judgment of non-infringement in the Northern District of California. The district court dismissed the complaint, relying on the Federal Circuit’s 1998 decision in Red Wing Shoe v. Hockerson-Halberstadt, concluding that it would be unreasonable to assert personal jurisdiction over PerDiem based on its communications. Trimble appealed.

The sole issue in the appeal was whether the district court erred in holding that there was no specific personal jurisdiction over PerDiem in the Northern District of California. The Federal Circuit explained that PerDiem’s contacts with California were far more extensive than those in Red Wing, noting the manner in which PerDiem amplified its threats of infringement as the communications continued, asserted more patents, and accused more of Trimble and ISE’s products of infringement. The Court noted that PerDiem even identified the counsel it retained to sue Trimble and the venue in which it planned to file suit. Overall, the Court found that PerDiem’s 22 communications over the course of about three months fell well outside the “sufficient latitude” the Court sought to grant patentees “to inform others of [their] patent rights without subjecting [themselves] to jurisdiction in a foreign forum” on the basis of three letters sent over a similar time period in Red Wing.

Practice Note: It remains to be seen how useful this case may be in the context of obtaining specific personal jurisdiction over non-practicing entities (or other patent owners) based on sending demand letters into a potential declaratory judgment venue viewed as less hospitable to patent owners.

Arthrex Argument May Be Available in Round Two

The US Court of Appeals for the Federal Circuit found that a party did not waive the Patent Trial & Appeal Board’s (Board) constitutionality argument by raising it for the first time in its opening brief because the Court’s decision in Arthrex, Inc. v. Smith & Nephew, Inc. was issued after the party sought rehearing. New Vision Gaming v. SG Gaming, Inc., Case Nos. 20-1399, -1400 (Fed. Cir. May 13, 2021) (Moore, J.) (Newman, J. concurring in part, dissenting in part)

New Vision appealed two covered-business method (CBM) review final written decisions in which the Board found that all claims of the patents, as well as its proposed substitute claims, were directed to patent ineligible subject matter under 35 U.S.C. § 101. In its opening brief before the Federal Circuit, New Vision requested the Court vacate and remand the Board’s decisions in light of Arthrex. SG Gaming argued New Vision had waived its right to a challenge under Arthrex since it raised it for the first time on an appeal. The Court disagreed, finding that New Vision had not waived its ability to challenge the Board’s decision under Arthrex since Arthrex was issued after the Board’s final written decisions and after New Vision sought Board rehearing. The Court vacated the Board’s final written decisions in the CBMs and remanded for further proceedings consistent with Arthrex without reaching the merits or any other issues.

In her partial dissent, Judge Pauline Newman agreed that Arthrex applied and vacating the Board’s final written decisions was appropriate. She also argued that another threshold issue (venue) should have been resolved, rendering the remand under Arthrex unnecessary and unwarranted. Additionally, Judge Newman agreed with New Vision that since the parties agreed to a different forum for dispute resolution in their license agreement, compliance with the parties’ patent license agreement would be appropriate. Under that agreement, if “any dispute” arose, jurisdiction would be “exclusive” in the appropriate federal or state court in the state of Nevada. New Vision filed suit in the federal district court in Nevada before SG filed CBM petitions before the Board. The Board stated it “[does] not discern, nor has Patent Owner pointed to, any portions of chapter 32 or § 18 of the AIA, or authority otherwise, that explicitly provide for a contractual estoppel defense,” in its decision and proceeded to a final decision despite the forum selection agreement.

Both parties briefed the forum selection question, with New Vision citing the Federal Circuit 2019 decision in Dodocase VR v. MerchSource in which a case was removed from the Board based on an agreed choice of forum. SG countered that the Board’s rejection of choice of forum is an unreviewable “institution” decision under Thryv vs. Click-to-Call. Andrei Iancu, the Director of the US Patent and Trademark Office (USPTO), intervened in the appeal, arguing that the Board’s decision is “final and nonappealable” under 35 U.S.C. § 324(e). As to the Board’s “conduct” in declining to [...]
