Attorney’s Fees Properly Awarded in Unsuccessful Trade Secret Misappropriation and Civil Theft Suit

by | Aug 26, 2020 |

The US Court of Appeals for the Fifth Circuit affirmed a take-nothing judgment and an attorney’s fees award against plaintiffs in a trade secret misappropriation and civil theft suit under Texas law, finding that the fee award did not need to be segregated to various claims. ATOM Instrument Corp. v. Petroleum Analyzer Co., L.P., Case Nos. 19-29151, -20371 (5th Cir. Aug. 7, 2020) (Southwick, J.). The Court also remanded for an additional award of appellate attorney’s fees.

Olstowski was a consultant for Petroleum Analyzer Co., L.P. (PAC), during which time he developed a krypton-chloride-based excimer lamp to detect sulfur with ultraviolet fluorescence. Although he developed the lamp independently, he used PAC resources to test the technology.  Olstowski and PAC negotiated but failed to agree on licensing. Olstowski founded ATOM Instrument to assist him in the licensing discussions. Subsequently, PAC filed a declaratory judgment action in Texas court alleging that it owned the lamp technology. The state court ordered the claim to arbitration. The arbitration panel declared Olstowski the owner of the technology and enjoined PAC from using it. The state court confirmed the arbitral award, and a Texas appellate court upheld the confirmation order.

PAC thereafter developed a new sulfur-detecting excimer lamp called MultiTek that also used krypton-chloride with UV fluorescence. Olstowski and ATOM filed in state court for contempt of the injunction, but the state court denied the contempt motion as moot because PAC had ceased selling MultiTek.

ATOM filed for bankruptcy the following year. Olstowski and ATOM initiated a district court proceeding against PAC alleging misappropriation of trade secrets, unfair competition and civil theft. After holding a bench trial, the court found that MultiTek did not practice Olstowski’s technology and therefore entered a take-nothing judgment in favor of PAC. The district court also awarded attorney’s fees to PAC under a provision of the Texas Theft Liability Act (TTLA) that awards fees to prevailing parties. Olstowski and ATOM appealed both issues, and PAC sought an award of its appellate attorney’s fees.

As to liability, ATOM argued that the district court erred in finding that the MultiTek lamp did not practice Olstowski’s technology. ATOM characterized the error as a legal one regarding interpretation of the arbitral award, but the Fifth Circuit held that “whether one company used another’s protected technology” is a factual question for which Olstowski and ATOM had failed to carry the burden of proof at trial. ATOM further argued that the district court had ignored the alleged law of the case in deviating from the scope of technology defined in the arbitral award, but the Court again rejected ATOM’s argument because the district court had explicitly stated that the description of Olstowski’s technology in the arbitral award remained in effect.

As to the award of attorney’s fees, ATOM argued that the district court had not appropriately segregated fees related to the TTLA claim from those related to other claims. Applying Texas law, the Fifth Circuit affirmed that the TTLA claim was sufficiently related to the other claims [...]

Copyright Board Ordered to Take a New Look at Streaming Services Rate Structure

by | Aug 26, 2020 |

Reversing the Copyright Royalty Board’s (Board) determination of a revised rate structure governing musical works, the US Court of Appeals for the District of Columbia Circuit concluded that the Board reached a final structure without providing adequate notice. George Johnson v. Copyright Royalty Bd., Case No. 2019-1028 (D.C. Cir. Aug. 7, 2020) (Millett, J.).

Every five years, the Board holds a proceeding to determine the royalty rate and terms for reproducing and distributing musical works, where interested stakeholders are permitted to present evidence and argument. At issue in Johnson is the Board’s decision, made after a five-week evidentiary hearing, setting the compulsory rate for the right to reproduce and distribute recordings of copyrighted musical works, known as a mechanical license, through streaming services for the period of January 1, 2018, to December 31, 2022.

Before the Board’s determination, depending on the type of service provided, the service provider owed a royalty based on a formula that considered two factors: (1) the service provider’s revenue associated with the particular offering, known as the “revenue prong,” and (2) the royalties paid by the service provider to sound recording copyright holders, known as the “total content cost prong.” For some streaming service offerings, the royalty was subject to a mechanical floor, and for some, the total content cost prong was subject to a cap. The Board’s final determination uncapped the total content cost prong and decided to phase in, for all categories over five years, a 15.1% revenue rate and a 26.2% total content cost rate, both higher than prior rates. Streaming services Amazon, Google, Pandora and Spotify, along with copyright owners and pro se songwriter George Johnson, appealed various aspects of the ruling.

On appeal, the challenges ran the gamut of administrative arguments: among others, that the Board’s decision was improperly retroactive, that the Board failed to give proper notice before settling on the rate structure in its final determination and fixed rates arbitrarily and capriciously, that it rejected certain evidence without an adequate explanation, and that it made certain changes to its decision without statutory authority to do so.

Although the D.C. Circuit found most of these arguments unavailing, it was convinced of a few, warranting remand to the Board for further proceedings. Primarily, the Court concluded that the Board failed to provide proper notice that it would uncap the total content cost prong combined with a significant increase in the mechanical royalty license rate. Specifically, the Court held that the Board’s ultimate rate structure, while adopting pieces from various proposals (some of which were never even offered at or before the hearing), was not within the zone of reasonably contemplated outcomes. By eliminating the cap on total content cost for all categories and increasing the royalty rates, the mechanical royalty licenses would be subject to the copyright owners’ unchecked market power.

The D.C. Circuit found two other errors. First, the relevant stakeholders had a settlement history from which the Board could draw conclusions regarding an appropriate rate structure. Nonetheless, the [...]

Diamonds to Dust? Too Many Factual Disputes Precludes Summary Judgment

by | Aug 26, 2020 |

The US Court of Appeals for the Second Circuit vacated a district court’s summary judgment grant in favor of a fine jewelry producer for trademark infringement, counterfeiting and unfair competition because factual disputes exist around whether the accused infringer’s use of the word “Tiffany” was merely descriptive of a particular ring setting, thereby supporting a fair use defense to infringement. Tiffany and Company v. Costco Wholesale Corporation, Case Nos. 17-2798-cv, -19-338, -19-404 (2nd Cir. Aug. 17, 2020) (Livingston, J.).

In 2012, a Costco customer alerted Tiffany that she believed Costco was selling diamond engagement rings advertised as Tiffany rings. When Tiffany approached Costco about the issue in December 2012, Costco asserted that its point-of-sale displays bearing the Tiffany name referred to the diamond setting styles of its rings, and that other similar point-of-sale displays also identified common ring settings such as “bezel” or “cathedral” settings. Costco also claims that within one week after Tiffany’s December 2012 outreach, it voluntarily removed all uses of “Tiffany” from its jewelry displays and has not since used the word “Tiffany” to identify any rings or setting styles.

Nevertheless, in 2013, Tiffany filed suit against Costco for trademark infringement and counterfeiting under the Lanham Act, and unfair competition in violation of New York state law, based on Costco’s sales of otherwise unbranded diamond engagement rings identified by point-of-sale signs containing the word “Tiffany.” In response, Costco raised the affirmative defense of fair use, arguing that its use of “Tiffany” on certain signage for rings was not as a source-identifying trademark, but merely to describe a particular six-prong diamond setting style. Costco also filed a counterclaim seeking to cancel certain federal trademark registrations for the TIFFANY mark as “generic” for a specific jewelry setting, and not entitled to registered trademark protection.

The district court granted Tiffany’s motion for summary judgment finding Costco liable for trademark infringement and counterfeiting as a matter of law. The district court then revised a jury’s damages award finding that Costco was liable for willful or intentional infringement to the tune of more than $21 million. Costco appealed.

On appeal, Costco argued it had successfully raised a question of material fact as to its liability for trademark infringement and counterfeiting and was entitled to present its fair use defense to a jury. The Second Circuit addressed the lower court’s trademark “likelihood of confusion” assessment under its own Polaroid factors and explained that if a factual inference must be drawn to arrive at a particular finding on a Polaroid factor, and if a reasonable trier of fact could reach a different conclusion, the district court may not properly resolve that issue on summary judgment. Here, the Court determined that Costco raised a triable question of fact as to at least three of the Polaroid factors, namely, (1) whether Costco’s customers were actually confused as to the source or affiliation of its diamond engagement rings, (2) whether Costco adopted Tiffany’s trademark in bad faith and (3) whether the relevant population of consumers was sufficiently [...]

Standard Essentiality Is a Question for the Fact Finder

by | Aug 20, 2020 |

Affirming a jury verdict of infringement, the US Court of Appeals for the Federal Circuit concluded that the question of whether patent claims are essential to all implementations of an industry standard should be resolved by the trier of fact. Godo Kaisha IP Bridge 1 v. TCL Comm. Tech. Holdings Ltd., Case No. 19-2215 (Fed. Cir. Aug. 4, 2020) (O’Malley, J.).

IP Bridge owns patents that it contends are essential to the Long-Term Evolution (LTE) standard, and accused TCL of infringing the patents based on the sale of LTE-compliant mobile phones and tablets. Relying on the Federal Circuit’s 2010 decision in Fujitsu Ltd. v. Netgear Inc., IP Bridge presented evidence at trial that (1) the asserted claims are essential to mandatory sections of the LTE standard and (2) the accused products comply with the LTE standard. TCL did not present any evidence to counter that showing. The jury found that TCL was liable for infringement of the asserted claims and awarded damages. Following the verdict, TCL filed a motion for judgment as matter of law, contending that IP Bridge could not rely on the methodology approved in Fujitsu because Fujitsu only approved that methodology in circumstances where the patent owner asks the district court to assess essentiality in the context of construing the claims of the asserted patents. The district court rejected TCL’s argument and concluded that substantial evidence supported the jury’s verdict. TCL appealed.

The Federal Circuit affirmed the district court’s rulings but explained that it was writing to refute TCL’s contention that whether a patent is essential to a standard is a question of law to be resolved in the context of claim construction. TCL argued that while standard compliance may be used to prove infringement, a district court must make a threshold determination as part of claim construction that all implementations of a standard infringe the claims. TCL argued that since IP Bridge never asked the district court to conduct such an analysis, the question should not have gone to the jury. IP Bridge responded by arguing that whether a patent is essential to a standard is a classic fact issue and is in the province of the factfinder.

The Federal Circuit agreed with IP Bridge and found that TCL’s appeal rested on a misreading of Fujitsu. In Fujitsu, the Court noted that if a district court finds that the claims cover any device that practices a standard, then comparing the claims to that standard is the same as the traditional infringement analysis of comparing the claims to the accused product. The Court explained that the passing reference to claim construction is a recognition that the first step in any infringement analysis is claim construction; it is not a statement that the district court must determine whether the claim covers every implementation of the standard. The Court also explained that determining standard essentiality of patent claims during claim construction does not make sense from a practical perspective because essentiality is a question about whether the claim elements [...]

Senator Tillis Urges USPTO to Adopt Patent Reform Proposals

by | Aug 18, 2020 |

On August 10, 2020, Senator Thom Tillis of North Carolina urged the Director of the United States Patent and Trademark Office (USPTO), Andrei Iancu, to adopt two patent reform proposals suggested by Lisa Larrimore Ouellete and Heidi Williams. Senator Tillis is the Chairman of the Senate Judiciary Committee’s Subcommittee on Intellectual Property. Stanford University professors Lisa Larrimore Ouellete and Heidi Williams proposed the reforms in a paper, Reforming the Patent System, The Hamilton Project, Policy Proposal 2020-12 (June 2020).

The first proposed reform would require patent applicants to more clearly distinguish between hypothetical experimental results and actual experimental results. The USPTO allows applicants to include so-called “prophetic examples” in a patent application. The patent applicant is supposed to distinguish between prophetic examples and actual working examples by the verb tense used to describe the example. Prophetic examples should be described in the present or future tense, while working examples should be described in the past tense. However, the verb tense is not always clear. Moreover, the verb tense distinction may not be appreciated by foreign language translators, scientists and engineers, especially in countries where prophetic examples are not allowed. Ouellette and Williams proposed that prophetic examples in patent applications be clearly labeled. This would reduce confusion by the public. Senator Tillis noted that confusing data in patent applications could be used to mislead the public and pump up profits for a company that has little to offer the economy or the public.

The second proposed reform would require patent owners to disclose ownership of patents in a more transparent and standardized manner. The lack of a transparent and standardized recording of patent assignments increases the costs and uncertainties of freedom-to-operate searches, licensing, negotiations and patent litigation. There is currently no requirement by the USPTO that the assignment records be updated when there is an ownership change of a patent. There is no requirement that hidden owners of patents be listed in an assignment record. Moreover, a single patent owner can be referred to by different names in different patents. Ouellette and Williams proposed: 1) Congress or the USPTO should require standardization of entity and inventor names across patent records, 2) Congress or the USPTO should increase incentives to record changes in patent assignments, and 3) at least for patents involved in litigation, parties having ownership interests in the patents should be identified.

Ouellette and Williams also proposed adjusting patent terms for pharmaceuticals so that pharmaceuticals that have to undergo a lengthy clinical trial would still have a sufficient patent term once they are approved by the Food and Drug Administration. However, patent term changes require a change to the patent statute, and therefore this proposal needs to be approved by Congress.

Senator Tillis explained that the two proposed reforms would enhance “the patent system so that it provides optimal incentives for innovators and inventors while also minimizing transactional costs that may discourage the development of new products.” Senator Tillis noted the two proposed reforms could be implemented by the USPTO [...]

Challenge to PTAB’s Finding of Non-Obviousness Fails to Pay Out

by | Aug 13, 2020 | ,

Addressing whether the Patent Trial and Appeal Board (PTAB) ran afoul of the Administrative Procedure Act (APA) in finding that a dependent claim was valid despite the patent owner’s lack of validity arguments beyond those advanced for the corresponding and invalid independent claim, the US Court of Appeals for the Federal Circuit affirmed the PTAB’s ruling and found no APA violation. FanDuel, Inc. v. Interactive Games LLC, Case No. 19-1393 (Fed. Cir. July 29, 2020) (Hughes, J.) (Dyk, J. concurring in part and dissenting in part).

Interactive Games owns a patent directed to a method for allowing users to gamble remotely via a mobile device, according to certain game configurations. Specifically, the independent claim is directed to altering a user’s game outcome based on the gaming configuration associated with the location of a user’s mobile gaming device. A dependent claim adds the additional limitation of “accessing a lookup table which contains an ordered list of locations and associated game configurations.”

FanDuel petitioned for inter partes review (IPR) of the patent as obvious based on three references. The first reference (Carter) disclosed a mobile wagering system capable of determining a gambler’s location and restricting access based on the location. Carter’s system used a database that correlated various locations with applicable access levels. Importantly, the reference generally indicated that the system may employ various components such as “memory elements, processing elements, logic elements, look-up tables, and the like.” The second reference (Walker) disclosed enabling or disabling certain features on a mobile gaming device based on a user’s location. And the third reference (the webpage) included a list of slot payouts by casino, city and state, alphabetically organized by state. FanDuel also submitted an expert declaration that the use of look-up tables was well known in the art and that it would have been an obvious design choice to store Carter’s jurisdictional information in an “ordered list” similar to the webpage.

In its Preliminary Patent Owner Response, Interactive incorporated its validity arguments for the independent claim into its arguments for the dependent claim, but did not otherwise advance any substantive arguments specific to the dependent claim. The PTAB instituted IPR for all challenged claims. Following institution, Interactive submitted a patent owner response, which again did not advance any substantive arguments specific to the dependent claim. While Interactive did submit an expert declaration, the statements made by FanDuel’s expert specific to the dependent claim were uncontested. Ultimately, the PTAB found the independent claim invalid, but found the dependent claim valid. FanDuel appealed.

FanDuel argued that the PTAB’s decision with respect to the dependent claim violated the APA because the PTAB changed its obviousness theory midstream. FanDuel alleged that no further record development was presented regarding the dependent claim after institution, and therefore a finding of validity in light of the PTAB’s decision to institute amounted to a changed position by the PTAB, to which FanDuel was entitled notice and an opportunity to respond.

The Federal Circuit disagreed and affirmed the PTAB’s decision. In finding [...]

Explain Yourself: “Untethered” Obviousness Determination Reversed

by | Aug 13, 2020 | ,

The US Court of Appeals for the Federal Circuit vacated in part and remanded a Patent Trial and Appeal Board (Board) determination of unpatentability because the Board did not adequately support its reasoning as to certain claims. Alacritech, Inc. v. Intel Corp., Case No. 19-1467 (Fed. Cir. July 31, 2020) (Stoll, J.).

Intel petitioned for inter parties review (IPR) of a patent owned by Alacritech that is directed to performing network processes on a dedicated network card (INIC) instead of on a computer’s central processing unit (CPU). Intel asserted that the claims would have been obvious over prior art Thia in view of Tanenbaum. The Board agreed, finding claims of the patent were obvious. Alacritech appealed.

Addressing the standard of review as set forth in the Administrative Procedure Act, the Federal Circuit explained that the Board is obligated to provide a record which shows the evidence on which its findings are based, as well as its reasoning in reaching its conclusions. While “perfect explanations” are not required, it must be sufficient for the Court to see that the agency has “done its job.” The Court found that the Board’s analysis as to three claims in the patent did not meet this standard.

The Court explained that the Board, after only briefly reciting the parties’ arguments, “merely concluded” that the relevant claim limitation was present in the subject claims and the prior art, and in so doing “misapprehend[ed] both the scope of the claims and the parties’ arguments.” The Court went on to explain that the crux of the dispute was where the claim limitation at issue took place—in the CPU (as in the prior art), or in the INIC (as required by the claims). The Court found that the Board’s analysis did not acknowledge this aspect of the parties’ dispute or explain how the prior art taught such a limitation. Without an explanation of its reasoning, the Court could not reasonably discern whether the Board followed the proper path in making its determination.

Intel argued that, while the Board did not itself expound on its reasoning, it did sufficiently support its position by citation to and adoption of Intel’s arguments. While the Federal Circuit noted that it has upheld Board determinations that flowed from the rejection or adoption of a party’s arguments, in this case the Board’s decision was “untethered from either party’s position.” Specifically, both parties focused their arguments on the Thia reference, while the Board relied on Tanenbaum to support its findings. Thus the Court was unable to infer the Board’s argument from those founded on a different basis.

The Federal Circuit also rejected as “fundamentally incorrect” Intel’s assertion that any evidentiary support in the record—even if not cited to by the Board—is sufficient to support the Board’s determination. The Court retorted that Intel’s sole citation to a footnote in a 2002 case was at odds with the clear precedent confining the Court’s review to the actual grounds on which the Board relied. Accordingly, the Court vacated the [...]

Check Step One: It’s Not Ova until the Court Compares Claims

by | Aug 13, 2020 |

The US Court of Appeals for the Federal Circuit reversed a district court’s decision finding a patent directed to a method of sorting particles using flow cytometry technology ineligible under 35 U.S.C. § 101. The Federal Circuit also vacated the district court’s conclusion that the patent owner was precluded from asserting certain patents based on claim preclusion. XY, LLC v. Trans Ova Genetics, LC, Case No. 19-1789 (Fed. Cir. July 31, 2020) (Stoll, J.).

XY, Beckman Coulter and Inguran (collectively, XY) sued Trans Ova in 2016 for infringement of seven patents relating to technology for sex selection of non-human mammals. Trans Ova filed a motion for judgment on the pleadings, arguing that the asserted claims of one of the patents are ineligible under 35 U.S.C. § 101. Applying the Supreme Court’s two-step Alice framework for determining patent eligibility, the district court determined that the claims are ineligible under § 101. At Alice step one, the district court found that the patent’s sole independent claim was directed to the abstract idea of a “mathematical equation that permits rotating multi-dimensional data.” At Alice step two, the district court found that the asserted claims lacked an inventive concept because XY admitted that each claim element was known in the art.

Trans Ova also filed a motion to dismiss, arguing that the district court should hold XY’s infringement allegations barred by claim preclusion. The argument was based on XY’s 2012 lawsuit against Trans Ova on infringement of different patents directed to similar technology (which was pending on appeal when the 2016 case was filed). The district court granted Trans Ova’s motion to dismiss infringement allegations of three patents cited in the 2016 suit, and stayed proceedings on XY’s remaining causes of action pending the outcome of the 2016 suit’s appeal. XY appealed the district court’s dismissal decision.

On appeal, the Federal Circuit found that the district court erred in finding that the claims are directed to a mathematical equation under Alice step one. The Court concluded that the asserted claims are directed to a patent-eligible improvement of a method of sorting particles using flow cytometry technology, not to an abstract idea. XY’s claim described detailed improvements to a physical technique, a step-by-step method for a laboratory process, which is patent eligible.

As to the issue of claim preclusion, the parties’ only dispute was whether the district court properly concluded that XY’s 2012 and 2016 lawsuits present the same cause of action. A cause of action is defined based on the transactional facts from which it arises, which in a patent case include both the asserted patents and the accused activity. Claim preclusion will be triggered by different patents only if the scope of the asserted patent claims in the two suits is essentially the same.

XY argued that the district court erred by failing to compare the currently asserted patent claims to the previously asserted patent claims to determine whether the causes of action in the two lawsuits are essentially the same. The Federal Circuit [...]

Unlikely to Succeed: Preliminary Injunction Denied Despite Stipulation to Irreparable Harm

by | Aug 13, 2020 |

In a dispute over the terms of a settlement agreement, the US Court of Appeals for the Federal Circuit found that a patent owner was not entitled to a preliminary injunction despite a stipulation that it would be irreparably harmed if the accused infringer breached certain provisions of the agreement. Takeda Pharmaceuticals U.S.A., Inc. v. Mylan Pharmaceuticals, Inc., Case Nos. 20-1407, -1417 (Fed. Cir. July 31, 2020).

Takeda originally sued Mylan to prevent Mylan’s launch of a generic version of Takeda’s branded drug Colcrys. The parties ultimately settled under terms set forth in a settlement/license agreement, including a provision in Section 1.2(d) stating that Mylan would be entitled to launch a generic product after a Final Court Decision holding that all unexpired claims of the licensed patents that were asserted and adjudicated against a third party were either (i) not infringed or (ii) any combination of not infringed and invalid or unenforceable. The licensed patents included 17 Orange-Book-listed patents that Takeda had asserted against Mylan. The parties further agreed that a breach of this provision “would cause Takeda irreparable harm.”

While Takeda and Mylan were negotiating the settlement, another patent litigation that involved some of the licensed patents was ongoing (the West-Ward litigation). The West-Ward litigation involved a different party and a different drug product. Takeda did not assert all 17 patents in the West-Ward litigation. It only asserted eight and ultimately dismissed five with prejudice. On summary judgment, the district court in the West-Ward litigation found that the asserted claims of the remaining three patents were not infringed.

Mylan informed Takeda that it would launch its generic product, arguing that summary judgment in the West-Ward litigation triggered Section 1.2(d), allowing it to launch its generic product because all of the asserted claims remaining in the suit had been found not infringed. In response, Takeda filed a complaint alleging breach of contract and patent infringement, and sought a preliminary injunction to enjoin Mylan from its launch. The preliminary injunction motion was denied. Takeda appealed.

A plaintiff seeking a preliminary injunction must show (i) that it is likely to succeed on the merits, (ii) that it will suffer irreparable harm in the absence of preliminary relief, (iii) that the balance of equities tips in its favor, and (iv) that an injunction is in the public interest. The Federal Circuit’s decision focused on the first two factors: likelihood of success and irreparable harm.

The Federal Circuit’s analysis of the likelihood of success prong turned on the meaning of Section 1.2(d). Takeda argued that Section 1.2(d) had not been triggered because not all unexpired claims that were asserted in the West-Ward litigation had been found not infringed, specifically the asserted claims of the five withdrawn patents. Mylan argued that triggering Section 1.2(d) only required that all unexpired claims that had been asserted and adjudicated to be found not infringed or invalid, and because the asserted claims of the five dismissed patents were not adjudicated, it was not necessary that the dismissed claims be [...]

“Method of Preparation” Claims Still Patent Eligible Under § 101 in Modified Opinion

by | Aug 13, 2020 |

The US Court of Appeals for the Federal Circuit denied an accused infringer’s petition for rehearing en banc and issued a modified opinion with additional analysis maintaining its prior finding that patent claims directed to a method of preparation were patent eligible. Illumina, Inc. v. Ariosa Diagnostics, Inc., Case No. 19-1419 (Fed. Cir. Aug. 3, 2020) (Lourie, J.) (Reyna, J., dissenting).

In its original decision in Illumina v. Ariosa, the Federal Circuit found that claims directed to methods of preparing a fraction of cell-free DNA that is enriched in fetal DNA were not directed to a patent-ineligible natural phenomenon. In its modified opinion, the Court again concluded that the claims were patent eligible under § 101 because they were not directed to a natural phenomenon, but to an exploitation of that natural phenomenon, by inventing a method for preparing a mixture enriched in fetal DNA that selectively removed maternal DNA. In the modified opinion, the majority further explained that the claimed size thresholds were not dictated by any natural phenomenon, but were “human-engineered parameters that optimize the amount of maternal DNA that is removed from the mixture and the amount of fetal DNA that remains in the mixture in order to create an improved end product that is more useful for genetic testing than the original natural extracted blood sample.” The Court emphasized that the claimed methods achieve more than an observation or detection of a natural phenomenon because the claims include “physical process steps that change the composition of the mixture, resulting in a DNA fraction that is different from the naturally occurring fraction in the mother’s blood.” The Court distinguished Myriad by stating that the claims were ineligible in that case because they covered a gene that the inventors isolated but did not invent, whereas in this case, the inventors claimed an innovative method using human-engineered size parameters to perform the separation—not the separated DNA itself. The Court concluded that the claimed methods were patent eligible under § 101 because they “utilize the natural phenomenon that the inventors discovered by employing physical process steps and human-engineered size parameters to selectively remove larger fragments of cell-free DNA and thus enrich a mixture in cell-free fetal DNA.”

Judge Reyna again dissented, arguing that the claims were patent ineligible under § 101 because they were directed to an undisputed natural phenomenon (i.e., the “surprising” discovery of size discrepancy of cff-DNA in a mother’s blood), and the application of the natural phenomenon used routine steps and conventional procedures that are well known in the art. He explained that “[l]ike in Alice, the claims here are directed to a natural phenomenon because they involve a fundamental natural phenomenon, that cff-DNA tends to be shorter than cell-free maternal DNA in a mother’s blood, to produce a ‘mixture’ of naturally-occurring substances.” Judge Reyna argued that the majority ignored the Court’s “claimed advance precedent” by reasoning that the claims belong in a distinct category of “method of preparation” claims, but such characterization should be treated [...]
