Sprint fires off lawsuit at cable giants

Sprint Nextel has sued several cable providers over what it claims is the illegal use of its digital phone technology, further fraying an already strained relationship between the carrier and the cable industry.

In separate lawsuits filed yesterday, Sprint alleged that Comcast, Time Warner Cable, Cox Communications, and the Washington Post's Cable One all infringed on 12 patents related to digital phone technology it secured in the '90s.
