Omaha Company Suing Cell Phone Providers

An Omaha company is suing five cell phone service providers for allegedly using its patent-protected computer technology without permission. Prism Technologies alleges that the companies took advantage of a system that controls which smart phones, tablets and broadband mobile cards can access an Internet service. The lawsuits in U.S. District Court of Nebraska were filed against AT&T, Verizon Wireless, T-Mobile USA, Sprint PCS and U.S. Cellular. The lawsuit says the company secured a patent for its inventions in October 2007. The company is seeking royalty payments with interest, as well as a judge's order for the companies to stop the alleged violation.
