Walgreens Sues Rite Aid, CVS, Shopko Over Mobile Refill Scans

Walgreens, armed with a new patent, sued Rite Aid, CVS and Shopko Stores Inc., claiming they're misappropriating its technology for refilling prescriptions with mobile phone scanners. Walgreens, the largest U.S. drugstore chain, with $72 billion in sales last fiscal year, got a patent last month for a system to "express refill" prescriptions and is entitled to exclusive use of the invention, the Deerfield, Ill.-based company said in complaints filed Jan. 31 in federal court in Wilmington, Del.
