Dobson Cellular Systems, Inc.

Dobson Cellular Systems, Inc. ("Dobson Cellular") was the wireless operating subsidiary of Oklahoma City–based Dobson Communications Corporation, headquartered at 14201 Wireless Way, Oklahoma City, Oklahoma. The Dobson telephone business dates to the 1920s as an Oklahoma wireline carrier; Dobson entered wireless in 1990 and grew into the largest independent rural wireless provider in the U.S. The parent was publicly traded on Nasdaq (ticker DCEL). In 2006 Dobson reported roughly $1.3 billion in revenue and about 1.7 million subscribers across 17 states, making it the ninth-largest U.S. wireless carrier by subscribers. AT&T Inc. (NYSE: T) agreed to acquire Dobson on June 29, 2007 for approximately $2.8 billion (~$13/share) plus assumption of about $2.3 billion in debt; the deal closed November 15, 2007, and Dobson became part of AT&T Mobility.

Operations. Dobson Cellular sold wireless voice and data service under the Cellular One brand in rural and suburban markets, primarily in the Midwest, Alaska, and other regions. Its network ran AMPS/D-AMPS and GSM/GPRS/EDGE on 850 MHz and 1900 MHz spectrum, and it provided voice and data roaming to other carriers. The company bought rights to the Cellular One name from Alltel in December 2005 and, through affiliate Cellular One Properties, LLC, licensed the brand to roughly nine other carriers. It also served resellers and MVNOs such as TracFone.

Litigation posture. An operating company, not an NPE: Dobson appears once in the tracked data, as a defendant with zero plaintiff cases. The single suit, Freedom Wireless, Inc. v. American Cellular Corp. et al. (E.D. Tex., filed April 2007), was a patent-infringement action brought against Dobson Cellular alongside American Cellular and Ericsson. It was filed in the Marshall Division of the Eastern District of Texas, a plaintiff-friendly venue, before Judge T. John Ward.

Context. Freedom Wireless was a patent-holding/licensing entity (successor to Cellexis) asserting prepaid-wireless billing patents; it had previously won a large verdict against Boston Communications Group (BCGI) and several carriers over the same portfolio. Dobson's involvement fits the pattern of a carrier defending a patent-assertion suit while its acquisition by AT&T was pending. Employee count and current financials are not available because the entity no longer exists as a standalone company.
