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

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 [...]

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

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 [...]

Technical Issues Affirm Patent Validity but Preclude Pre-Suit Damages

In a split decision, the US Court of Appeals for the Federal Circuit affirmed the subject matter eligibility of claims directed to collection, comparison and classification of information. The Court also unanimously found that the patent owner was not entitled to pre-suit or enhanced damages because it failed to prove pre-suit patent marking by its licensees. Packet Intelligence LLC v. Netscout Systems, Inc., Case No. 19-2041 (Fed. Cir. July 14, 2020) (Lourie, J.) (Reyna, J., dissenting in part).

This dispute began when Packet Intelligence sued Netscout for infringing three of its patents that were directed to a system and method for monitoring packets exchanged over a computer network. The case was tried before a jury, which found the patents-in-suit valid and infringed. The jury further determined that Packet Intelligence was entitled to pre-suit and post-suit damages, as well as enhanced damages. Netscout filed a motion for judgment as a matter of law that Packet Intelligence was not entitled to pre-suit damages, which the district court denied. Following a bench trial, the district court held that the claims of the patents-in-suit were not invalid under 35 USC § 101. Netscout appealed.

Netscout challenged the district court’s § 101 decision and the denial of Netscout’s motion for judgment as a matter of law on pre-suit damages. In a split panel decision, the Federal Circuit affirmed the district court’s determination on subject matter eligibility under § 101. Netscape specifically argued that the claims were directed to an abstract idea because the claims were merely directed to the collection, comparison and classification of information.

The majority reiterated that the Federal Circuit has recognized that software-based innovations may be deemed patent-eligible subject matter at Alice step 1. For example, in Enfish, the Court held that software claims were valid at step 1 because the claims were directed to a technical improvement over conventional systems. Similarly, in SRI International, the Court held that software claims were valid because the claims at issue were “necessarily rooted in computer technology in order to solve a specific problem in the realm of computer networks.” Applying these principles, the majority found that the claims were patent eligible because they presented a technical solution to a technical problem. Notably, the majority relied on the patent specification’s disclosures regarding the invention’s improvements over conventional systems.

Judge Reyna dissented. In his view, the claims were directed to an abstract idea because they lacked specific technological means for the collection, analysis and display of data. Because a concrete technical solution was absent, Reyna argued that the claims were distinguishable from the SRI International case on which the majority relied. He would have found the claims invalid under step 1 and remanded the case to the district court to fully address Alice step 2.

Regarding pre-suit damages, the Federal Circuit unanimously held that Packet Intelligence was not entitled to such damages. The primary issue was whether a Packet Intelligence licensee had properly complied with the marking requirements in order to provide the required constructive notice to [...]

Can’t Have Layered Architecture Cake and Eat It Too: No Importing Limitations from Specification in § 101 Analysis

Addressing both the availability of appeal in the absence of a Rule 50(b) motion and the appropriateness of importing limitations from the specification in a 35 USC § 101 analysis, the US Court of Appeals for the Federal Circuit reversed a district court’s ruling that a patent was not invalid under § 101. Ericsson Inc. v. TCL Commc’n Tech. Holdings Ltd., Case No. 18-2003 (Fed. Cir. Apr. 14, 2020) (Prost, CJ.) (Newman, J., dissenting).
