Before LOURIE, DYK, and CHEN, Circuit Judges.

LOURIE, Circuit Judge.

Braemar Manufacturing, LLC and CardioNet, LLC (collectively "CardioNet") appeal from two decisions of the United States District Court for the Eastern District of Pennsylvania holding that the asserted claims of U.S. Patents 7,941,207 ("the '207 patent), 7,212,850 ("the '850 patent"), 7,907,996 ("the '996 patent"), and 7,587,237 ("the '237 patent") are ineligible for patent under 35 U.S.C. § 101. CardioNet, LLC v. ScottCare Corp., 388 F. Supp. 3d 442 (E.D. Pa. 2019); CardioNet, LLC v. ScottCare Corp., 325 F. Supp. 3d 607 (E.D. Pa. 2018).

In light of our recent decisions in CardioNet, LLC v. InfoBionic, Inc., No. 20-1018 (Fed. Cir. July 1, 2020), and CardioNet, LLC v. InfoBionic, Inc., 955 F.3d 1358 (Fed. Cir. 2020), we affirm as to the '850 and '996 patents, vacate the district court's judgment of ineligibility of the asserted claims of the '207 patent, and remand for further proceedings on the '207 patent. Because we conclude that the asserted claims of the '237 patent recite patent-ineligible subject matter, we affirm the district court's decision with respect to that patent.

BACKGROUND

CardioNet owns the '207, '850, '996, and '237 patents (collectively "the asserted patents"), which are generally directed to systems and methods for cardiac monitoring. In 2012, CardioNet sued The ScottCare Corporation ("ScottCare") for infringement of the asserted patents in the Eastern District of Pennsylvania. Subsequently in 2015, CardioNet sued InfoBionic, Inc. for infringement of the '850 and '996 patents in the District of Massachusetts. In 2017, CardioNet brought an additional claim against InfoBionic in the District of Massachusetts for infringement of the '207 patent.

On May 4, 2017, the Massachusetts district court issued an order determining that certain claims of the '850 and '996 patents are ineligible for patent under 35 U.S.C. § 101. CardioNet, LLC v. InfoBionic, Inc., 2017 WL 1788650 (D. Mass. 2017) ("'850/'996 Mass. Decision"). Thereafter, in this case, ScottCare filed a motion for judgment on the pleadings as to the '850 and '996 patents, arguing that CardioNet was collaterally estopped from continuing to assert infringement of those patents based on the determination of ineligibility in the '850/'996 Mass. Decision. The Pennsylvania district court granted ScottCare's motion on July 12, 2018. CardioNet, LLC v. ScottCare Corp., 325 F. Supp. 3d 607, 613 (E.D. Pa. 2018).

On September 11, 2018, ScottCare filed an additional motion for judgment on the pleadings, arguing that the asserted claims of the '207 and '237 patents are ineligible for patent under § 101. Before the Pennsylvania district court ruled on ScottCare's motion, the Massachusetts district court issued a second order determining that claims 1-3, 7, 10-12, and 22 of the '207 patent are ineligible for patent under § 101. CardioNet, LLC v. InfoBionic, Inc., 348 F. Supp. 3d. 87 (D. Mass. 2018) ("'207 Mass. Decision"). In this case, CardioNet also asserted claims 8, 9, 21, and 23 of the '207 patent. ScottCare filed additional briefing in the Pennsylvania district court arguing that CardioNet was collaterally estopped from continuing to assert infringement of all asserted claims of the '207 patent based on the '207 Mass. Decision, including the claims that were not specifically addressed by the Massachusetts district court.

On July 11, 2019, the Pennsylvania district court granted ScottCare's motion. CardioNet, LLC v. ScottCare Corp., 388 F. Supp. 3d 442 (E.D. Pa. 2019) ("'207/'237 Pa. Decision"). Regarding the '207 patent, the district court held that CardioNet was collaterally estopped from asserting claims 1-3, 7, 10-12, and 22 of the '207 patent based on the '207 Mass. Decision. Id. at 460. The court held that CardioNet was also collaterally estopped from asserting claims 8, 9, 21, and 23, which were not addressed in the '207 Mass. Decision, because the court determined that the differences between those claims and the previously-adjudicated claims do not materially alter the question of validity under § 101. Id. at 462-66.

Regarding the '237 patent, the court determined that the asserted claims are ineligible for patent under § 101. The district court treated claims 25 and 37 as representative of those asserted, and CardioNet does not challenge that determination on appeal. Claim 37 recites:

37. An article comprising one or more machine-readable media storing instructions operable to cause one or more machines to perform operations for monitoring a cardiac biological signal using electrocardiographic monitoring instrumentation, the operations comprising:

receiving a cardiac biological signal that includes information describing events, wherein events comprise periods in time when an information content of the cardiac biological signal is of increased relevance to a particular purpose and the events are demarcated by periods of time that are not of increased relevance to the particular purpose;

determining a measure of merit of information describing each event, wherein the measure of merit embodies both the severity of the cardiac condition indicated by the information describing the event and an amount of noise in the information describing the event;

comparing the measure of merit of information describing the event with a merit criterion; transmitting, for medical purposes, information describing a first proper subset of the events that have measures of merit meeting the merit criterion to a remote medical receiver; and

discarding information describing a second proper subset of the events that have measures of merit that fail to meet the merit criterion.

'237 patent col. 18 l. 59-col. 20 l. 3.

The district court considered the claims of the '237 patent under the Supreme Court's two-step Alice framework for determining patent-eligibility. At step one, the court determined that the claims are directed to the abstract idea of "collecting, classifying, or otherwise filtering data into different groups based on identifying characteristics and transmitting relevant information for review." '207/'237 Pa. Decision, 388 F. Supp. 3d at 454. At step two, the court concluded that "[t]he claim elements, individually or collectively, recite performing the abstract idea with conventional technology and fail to provide any specific, inventive technological improvement." Id. at 456.

The district court entered final judgment of patent invalidity of the '207, '237, '850, and '996 patents in favor of ScottCare, and CardioNet appealed. We have jurisdiction under 28 U.S.C. § 1295(a)(1).

DISCUSSION

We review a district court's grant of judgment on the pleadings under Rule 12(c) according to the law of the regional circuit. Allergan, Inc. v. Athena Cosmetics, Inc., 640 F.3d 1377, 1380 (Fed. Cir. 2011) (citing Imation Corp. v. Koninklijke Philips Elecs. N.V., 586 F.3d 980, 985 (Fed. Cir. 2009)). The Third Circuit reviews orders granting judgment on the pleadings de novo. Zimmerman v. Corbett, 873 F.3d 414, 417 (3d Cir. 2017) (citing Allah v. Al-Hafeez, 226 F.3d 247, 249 (3d Cir. 2000)).

I. '207 Patent

This court recently reversed the '207 Mass. Decision and held that claims 1-3, 7, 10-12, and 22 of the '207 are patent-eligible. CardioNet, LLC v. InfoBionic, Inc., 955 F.3d 1358 (Fed. Cir. 2020). Here, CardioNet has also asserted claims 8, 9, 21, and 23. Because the judgment underlying the district court's application of collateral estoppel has been reversed, we vacate the district court's judgment of ineligibility of all of the asserted claims of the '207 patent and remand for further proceedings.

II. '850 and '996 Patents

This court recently affirmed the '850/'996 Mass. Decision holding that claims 1-3, 5-6, 8-9, 21, and 31-32 of the '850 patent and claims 12 and 23 of the '996 patent are patent-ineligible. CardioNet v. InfoBionic, Inc., No. 20-1018, slip op. at 2 (Fed. Cir. July 1, 2020). Here, CardioNet has asserted claims 31 and 32 of the '850 patent and claims 1, 12, and 23 of the '996 patent. Because the judgment underlying the district court's application of collateral estoppel has been affirmed and CardioNet does not otherwise argue that the district court erred in its application of the doctrine, we affirm the district court's judgment of invalidity of claims 31 and 32 of the '850 patent and claims 12 and 23 of the '996 patent. Because claim 1 of the '996 patent recites materially indistinct subject matter from claim 12, we affirm the district court's judgment of invalidity of that claim as well.

III. '237 Patent

We now address the eligibility of the asserted claims of the '237 patent. Patent eligibility under § 101 is an issue of law that may involve underlying issues of fact. See Berkheimer v. HP Inc., 881 F.3d 1360, 1365 (Fed. Cir. 2018) (citing Mortg. Grader, Inc. v. First Choice Loan Servs. Inc., 811 F.3d 1314, 1325 (Fed. Cir. 2016)). We review the district court's ultimate conclusion on patent eligibility de novo. Id.

To determine whether a patent claims eligible subject matter, we follow the Supreme Court's familiar two-step framework. See Alice Corp. v. CLS Bank Int'l, 573 U.S. 208, 217 (2014); Mayo Collaborative Servs. v....
