Defendant
2 cases as defendant.
NortonLifeLock Inc. was the corporate name of the consumer cybersecurity company now known as Gen Digital Inc. (Nasdaq: GEN). The NortonLifeLock name was adopted in 2019 after Broadcom acquired Symantec's enterprise security business; the company changed its name to Gen Digital in November 2022 following its merger with Avast. It is headquartered in Tempe, Arizona, with major operations in Prague. Its corporate lineage traces to Symantec, founded in 1982. It is publicly traded, with roughly 3,400–3,900 employees, revenue of about $3.9 billion in fiscal 2025 (ended March 2025) and reported figures near $5.0 billion for fiscal 2026, and a market capitalization in the $16–18 billion range.
The company is an operating company, not a non-practicing entity. It sells subscription-based consumer "cyber safety" software and services: device security (Norton 360, Norton AntiVirus), VPN and online privacy, parental controls (Norton Family), and identity-theft protection and restoration (LifeLock). Its brand portfolio also includes Avast, AVG, Avira, CCleaner, and ReputationDefender; press accounts report an April 2025 acquisition of financial-wellness firm MoneyLion. Over 90% of revenue comes from recurring subscriptions.
Litigation posture: a two-way but defense-leaning litigant, consistent with the case data (2 appearances as defendant, 1 as PTAB petitioner/plaintiff). Notably, the opposing party is itself an operating company, Kajeet, Inc. (IoT connectivity for schools), not an NPE. All tracked matters sit in the District of Delaware or the PTAB — none in the Eastern District of Texas.
Notable matters: Kajeet sued NortonLifeLock in Kajeet, Inc. v. NortonLifeLock Inc. (D. Del., 1:20-cv-01339, filed October 2020, Judge Noreika), asserting U.S. Patent 8,667,559 on server-side, policy-based "feature management" of mobile devices — the technology behind parental-control products. NortonLifeLock also appears as a defendant in the related consolidated action Kajeet, Inc. v. Gryphon Online Safety, Inc. (D. Del., 1:19-cv-02370), where the court addressed § 101 eligibility. In turn, NortonLifeLock petitioned the PTAB in NortonLifeLock Inc. v. Kajeet, Inc. (October 2021, IPR2022-00001), challenging the Kajeet patent. Kajeet asserted the same patent family against other parental-control vendors, including Trend Micro, Asavie, and Qustodio.
Kajeet, Inc. sued Gryphon Online Safety, Inc. (and NortonLifeLock Inc. per one source). The court denied a Section 101 motion as to US 8,667,559 and US 7,899,438 but granted a motion to dismiss direct/indirect infringement with leave to amend.
Kajeet, Inc. sued NortonLifeLock Inc. in the District of Delaware before Judge Noreika. Exhibits in IPR2022-00001 reference interrogatories/RFAs served on Kajeet in this case; outcome not confirmed.
