SBC Internet Services, Inc. (also recorded in some filings as SBC Internet Services LLC) is a California-organized, wholly owned subsidiary of AT&T Inc. (NYSE: T). Its principal place of business is 2623 Camino Ramon, San Ramon, California, and it is also recorded as doing business as AT&T Internet Services. FCC Form 499 filings list Dallas-based officers and an AT&T Services, Inc. service agent. The entity is a corporate affiliate inside the AT&T family rather than a separately reporting company; no standalone revenue or headcount is disclosed. Parent AT&T is a large public telecom (roughly $122B revenue in 2024, ~140,000 employees), per its 10-K.
Operations. Per Bloomberg, SBC Internet Services offers internet access and web hosting services. It is the AT&T-branded internet-service affiliate whose lineage traces to predecessor SBC-family internet units — FCC records list aliases including AT&T Internet Services, Pacific Bell Internet Services, Southwestern Bell Internet Services, and Ameritech Interactive Media Services. Public utility filings describe it as an "administrative affiliate" with no customers of its own in several states; in 2016 it was merged into AT&T Corp. in an internal AT&T reorganization. It is an operating telecom/ISP entity, not a patent-assertion vehicle.
Litigation posture. The database shows one tracked case, all as defendant and none as plaintiff — the profile of an operating company being sued rather than a party asserting a portfolio. The sole matter sits in the U.S. District Court for the Northern District of Texas, Fort Worth Division.
Notable case. Vonage Holdings Corp. v. SBC Internet Services, Inc., No. 4:04-cv-00548-Y (N.D. Tex., Fort Worth), consolidated with Nortel Networks Inc. v. Vonage Holdings Corp., No. 4:05-cv-00224-Y. Vonage alleged SBCIS and co-defendants Sprint Communications, Central Telephone Company of Texas, and Bell Atlantic Communications (d/b/a Verizon Long Distance) infringed U.S. Patent No. 4,782,485, "Multiplexed Digital Packet Telephone System." The suit reflects the mid-2000s wave of VoIP/packet-telephony patent disputes involving Vonage, Sprint, Nortel, and Verizon. Outcome details are not reflected in the case data reviewed.
