- 5
In NetSoc v. Chegg, Judge Abrams dismissed NetSoc’s patent claims because an earlier ruling had already invalidated the patent.
NetSoc, LLC’s patent-infringement claims against Chegg Inc. were dismissed, and Chegg received the benefit of the earlier ruling that invalidated the asserted patent claims.
What happened
NetSoc, LLC sued Chegg Inc., claiming that Chegg’s website infringed NetSoc’s ’107 patent. Chegg moved to dismiss, including on the ground that the patent covered ineligible subject matter.
After another federal court invalidated the same patent claims in a case involving Match Group, NetSoc agreed that the earlier ruling barred its claims against Chegg. The court independently found that the requirements for issue preclusion were met.
Judge Abrams dismissed NetSoc’s claims against Chegg and directed the Clerk to close the case. The opinion does not independently decide whether the patent claims are valid; it applies the earlier invalidity ruling to this case.

Background
NetSoc, LLC brought a patent-infringement action against Chegg Inc. NetSoc alleged that Chegg’s website infringed one or more claims of U.S. Patent No. 9,978,107, which NetSoc owned by assignment. Chegg moved to dismiss under Federal Rule of Civil Procedure 12(b)(6), arguing, among other things, that the patent did not claim patent-eligible subject matter under 35 U.S.C. § 101.
The opinion concerns one of several infringement actions NetSoc filed in 2018. In a separate action against Match Group, LLC, the Northern District of Texas held that the ’107 Patent claims were directed to patent-ineligible abstract ideas and lacked an inventive concept under the two-step test from Alice Corp. Pty. Ltd. v. CLS Bank International. That court dismissed NetSoc’s claims with prejudice. NetSoc’s motion for a new trial was denied, and the Texas case was on appeal when the Southern District of New York ruled. The court stated that the pending appeal did not change the preclusion analysis.
Issue Preclusion
Issue preclusion, also called collateral estoppel, prevents a party from obtaining another decision on an issue that was already litigated and decided. The court identified four requirements: the issues must be identical; the issue must have been actually litigated and decided; the party must have had a full and fair opportunity to litigate it; and the issue must have been necessary to a valid, final judgment on the merits.
The court found all four requirements satisfied. Both cases involved NetSoc, the same ’107 Patent, and challenges under § 101 asserting that the patent claims covered abstract ideas without an inventive concept. The Northern District of Texas resolved the issue after full briefing and a hearing. The court also found that NetSoc had a fair opportunity and incentive to litigate the patent’s validity and that the § 101 ruling was necessary to the Texas court’s dismissal with prejudice.
Ruling
The court held that NetSoc’s claims against Chegg were barred by collateral estoppel. It dismissed those claims and directed the Clerk of Court to terminate the motion pending at docket entry 24 and close case number 18-CV-10262. The ruling applied the earlier invalidity decision rather than independently deciding the patent’s validity in the Chegg case.
