Arendi S.A.R.L. (“Arendi”) appeals from final judgments of the United States District Court for the District of Delaware holding that Google LLC (“Google”) and Oath Holdings Inc. (“Oath”) do not infringe the asserted claims of U.S. Patent No. 7,917,843 (the “’843 patent”) and that those claims are invalid as both anticipated and obvious over the prior art, and from the court’s grant of judgment on the pleadings under Federal Rule of Civil Procedure

ARENDI S.A.R.L. v. OATH HOLDINGS INC. 3

12(c) holding that the asserted claims of U.S. Patents No. 7,496,854 (the “’854 patent”), No. 7,921,356 (the “’356 patent”), and No. 8,306,993 (the “’993 patent”) are directed to patent-ineligible subject matter under 35 U.S.C. § 101. See Arendi S.A.R.L. v. Google LLC, No. 13-cv-919, Dkt. No. 616 (D. Del. Feb. 2, 2024) (“Final Judgment”); Arendi S.A.R.L. v. Google LLC, No. 13-cv-919, Dkt. No. 625 (D. Del. Jan. 14, 2026) (“Amended Final Judgment”); Arendi S.A.R.L. v. Google LLC, No. 13-cv-919, Dkt. No. 201 (D. Del. Jan. 2, 2020) (“Rule 12(c) Order”). Google argues as an alternative ground for affirmance that the ’843 patent is also directed to patent ineligible subject matter under section 101. For the following reasons, we affirm and hold that the asserted claims of each of the four patents claim patent ineligible subject matter under section 101. Accordingly, we do not reach the other issues.

BACKGROUND

Arendi filed two related infringement suits in the District of Delaware, one against Google and one against Oath. Arendi alleged that Google infringed the ’843 patent, the ’854 patent, the ’356 patent, and the ’993 patent. Arendi alleged that Oath infringed the ’843 patent, the ’356 patent , and the ’993 patent.

The ’843, ’356, and ’854 patents share a common specification . The ’993 patent has a similar specification and is directed to similar subject matter. The asserted patents generally concern identifying information in a document and using that information to search for related information in an external source, such as a contact database. See ’843 patent col. 1 l. 16–col. 2 l. 40.

The parties treat claim 1 of the ’843 patent, claim 93 of the ’854 patent, claim 2 of the ’356 patent, and claim 1 of the ’993 patent as representative. Since we write for the parties, we assume familiarity with the representative claim language.

After claim construction, Google and Oath moved for judgment on the pleadings under Rule 12(c), arguing that the asserted claims were directed to patent-ineligible subject matter under 35 U.S.C. § 101. Rule12(c) Order at 5–6. The district court granted the motion as to the representative claims of the ’854, ’356, and ’993 patents, but denied the motion as to the ’843 patent. Id. at 2.

The case then proceeded on the ’843 patent. Google moved for summary judgment of noninfringement as to asserted claims 23 and 30 of the ’843 patent. The district court granted the motion as to Google’s Linkify and Smart Linkify products because the alleged “documents” were not editable but denied the motion as to other Google products. Oath separately moved for summary judgment of noninfringement of claim 23 of the ’843 patent. The district court granted Oath’s motion, concluding that Arendi had not shown that Oath directly infringed the asserted computerreadable -medium claim. The district court then entered judgment in favor of Oath, and Arendi appealed.

The remaining Google claims proceeded to trial. The jury found that Arendi had not proven that Google infringed claims 23 or 30 of the ’843 patent and that Google had proven by clear and convincing evidence that those claims were invalid as anticipated and obvious. See Arendi S.A.R.L. v. Google LLC, No. 13-cv-919, 2024 WL 406405, at *1 (D. Del. Feb. 2, 2024) (“JMOL Order”). Arendi moved for judgment as a matter of law on anticipation and obviousness . Id. at *2. The district court denied Arendi’s motion , noting that because Google did not seek a declaratory judgment of invalidity, the Court “has discretion to not consider Arendi’s [invalidity] arguments” and elects to exercise that discretion to avoid “a waste of judicial resources.” Id. at *2–3. The district court then entered a judgment stating that “[j]udgment is entered in favor of Defendant and against Plaintiff on Plaintiff’s claim of patent infringement of U.S. Patent No. 7,917,843.” Final Judgment at 1. Arendi appealed.

ARENDI S.A.R.L. v. OATH HOLDINGS INC. 5

After oral argument, we ordered the parties to seek clarification from the district court as to whether the judgment rested on noninfringement alone or also incorporated the jury’s invalidity verdict. The district court entered an amended final judgment clarifying that the jury found noninfringement , anticipation, and obviousness as to claims 23 and 30 of the ’843 patent, and that “all of the jury’s findings remain undisturbed and have not been set aside.” Amended Final Judgment, at 1. Arendi timely appealed the amended judgment. We then consolidated the appeals and ordered supplemental briefing concerning Arendi’s appeal from the amended judgment.

DISCUSSION

I

The parties devote substantial attention to the scope of the district court’s final judgment and, relatedly, to what issues are properly before us on appeal. In particular, the parties initially disputed whether the judgment as to the ’843 patent rested solely on noninfringement or also incorporated the jury’s invalidity findings.

The district court’s amended judgment resolves that dispute. It clarifies that, as to the ’843 patent, the jury found both noninfringement and invalidity, and that “all of the jury’s findings remain undisturbed and have not been set aside.” Amended Final Judgment at 1. Thus, the judgment rests on both infringement and invalidity grounds as independent bases for judgment. Both infringement and invalidity are therefore before this court on appeal.

Google has preserved its invalidity arguments on appeal as to the ’843 patent. Google argued in its initial response brief that, like the other asserted patents, the ’843 patent is directed to ineligible subject matter, and it renewed that position in supplemental briefing following the amended judgment. Google Br. 36–39; Google Supp. Br. 5.
