Let me verify the litigation context and entity details.
Let me verify a couple of remaining details.
Alltel Communications, Inc. ("ACI") was a Delaware corporation and wholly owned subsidiary of Alltel Corporation, headquartered at One Allied Drive, Little Rock, Arkansas. ACI served as the group's principal U.S. wireless operating and financing subsidiary — borrower under Alltel's credit facilities and co-issuer of debt securities alongside Alltel Communications Finance, Inc. Its parent, Alltel Corp., traced to 1943 as Allied Telephone, took the Alltel name in 1983 after merging with Mid-Continent Telephone, and grew into the fifth-largest U.S. wireless carrier. Around 2007 Alltel reported roughly 12 million wireless customers, about $8 billion in annual revenue, and approximately 15,000 employees; it was a NYSE-listed company (ticker AT) until taken private in November 2007 by TPG Capital and GS Capital Partners in a $24.7 billion buyout. Verizon Wireless acquired Alltel Corp. in January 2009 for about $28.1 billion. Alltel Corporation remains a listed principal subsidiary of Verizon Communications. ACI itself was converted to Alltel Communications, LLC in 2009 and merged into WWC License LLC in 2015, per Arizona Corporation Commission records.
Operations: ACI operated CDMA/analog wireless service, primarily on the 850 MHz cellular band, including 3G 1xEV-DO data, prepaid service ("U Prepaid"), the unlimited-calling "My Circle" feature, and Wi-Fi hotspot offerings. Following Alltel's 2006 spinoff of its wireline business into Windstream, the Alltel group was wireless-only. The Alltel brand later survived under Atlantic Tele-Network's Allied Wireless (2010–2013) before AT&T acquired and retired it in 2016.
Litigation posture: ACI is a pure defendant in the tracked data — 0 plaintiff cases, 2 defendant cases — consistent with an operating carrier absorbing patent assertions rather than asserting patents itself.
Notable case: Freedom Wireless, Inc. v. Alltel Corp. et al., No. 2:06-cv-00504, filed Nov. 30, 2006 in the Eastern District of Texas, Marshall Division (Judge T. John Ward). Freedom Wireless, a small Phoenix patent holder that the Stanford NPE Litigation Database categorizes as an individual-inventor-started asserter, alleged infringement of prepaid cellular patents (including the '067, '823, and '851 patents) covering prepaid wireless billing and account-crediting methods. The case terminated in 2010. ACI's two tracked appearances are the same matter.
