I'll research this company to write an accurate profile.
Ericsson AB — Company Profile
Ericsson AB (Swedish reg. no. 556056-6258) is a Swedish telecommunications company and the principal operating subsidiary of Telefonaktiebolaget LM Ericsson (publ), which owns 100% of it, per Ericsson's Form 20-F filings. It is headquartered with the parent group at Torshamnsgatan 21, Kista, Stockholm. The parent traces its incorporation to August 18, 1918, and is publicly listed (Nasdaq Stockholm: ERIC B; Nasdaq: ERIC ADR). Group headcount was 94,236 at year-end 2024, and group net sales were about SEK 248 billion (~US$24 billion) in 2024.
Products / operations
Ericsson AB designs, manufactures and markets fixed and mobile telecommunications systems and equipment. Group reporting segments are Networks (radio access, base stations, 5G RAN — roughly two-thirds of sales), Cloud Software and Services (network management, systems integration, managed services), and Enterprise. Ericsson is an operating technology company and a major cellular-standard contributor (2G through 5G), not a patent-assertion entity; it holds a large standards-essential patent portfolio that it licenses, but it is not characterized here as an NPE.
Patent-litigation posture
The database shows Ericsson AB in one tracked case, as a defendant only (0 as plaintiff, 1 as defendant). That is consistent with an operating company being sued rather than an entity asserting patents. The single case sits in the U.S. District Court for the Eastern District of Texas, a historically plaintiff-friendly venue.
Notable case
Fenner Investments, Ltd. v. Juniper Networks, Inc. et al. (E.D. Tex., filed January 6, 2005) is the tracked matter. Plaintiff Fenner Investments — a Texas patent-holding limited partnership asserting patents acquired from inventor Peter R. Fenner — sued Juniper, Cisco, Nokia, Nortel, Lucent, UTStarcom and others over packet source-filtering technology (U.S. Patent Nos. 5,561,706 and 6,819,670). Ericsson AB, Ericsson Inc. and Telefonaktiebolaget LM Ericsson were added by amended complaint on May 17, 2005. Court records show Ericsson and Fenner executed a settlement and release; the related claims were dismissed without prejudice in 2006.
