PayOne has filed a patent infringement lawsuit against The Home Depot in the Northern District of California. In its complaint, PayOne asserts that The Home Depot retail store deployment and use of PayPal’s in-store checkout infringes on multiple PayOne patents including the use of a mobile phone number and a PIN to complete the checkout process and payment at point of sale. The complaint seeks unspecified damages and a court-ordered injunction against future infringement by The Home Depot. The asserted PayOne patents include United States Patent No. 7,848,500, entitled "Method And Apparatus To Validate A Subscriber Line"; and United States Patent No. 7,848,504, entitled "Method And Apparatus To Validate A Subscriber Line."
