A filing that appeared Tuesday in an east Texas court reveals that Google is being sued for patent infringement by Purple Leaf LLC, reports All About Patents. Purple Leaf claims that a patent related to online payments and receipts is being infringed upon by Google’s online payment systems, including Google Checkout.
Purple Leaf claims that “Google, Inc. has been and now is infringing the ‘311 Patent in the State of Texas, in this judicial district, and elsewhere in the United States by making, using, importing, selling or offering to sell services and products that practice methods and utilize devices for conducting a transaction using a medium based on a receipt having payment remittance information.”
The company then goes on to target Google Checkout stating, “Google, Inc. services that practice such methods and products that employ such devices include, but are not limited to “Google Checkout”, a service which allows a transaction to be conducted using a medium based on a receipt having payment remittance information.”
Because the suit applies to Google Checkout, which is used across Google’s empire, it would also apply to all Android phones and tablets. Note that the claims mention Google Checkout specifically, but also say that the patent may be infringed by other products that Google offers in the online payment space.
If the ruling is in its favor, Purple Leaf is looking to recoup damages related to loss of profits as well as court costs for pursuing the infringement case.
Currently, Purple Leaf LLC is also involved in patent suits with American Express, CitiGroup, Inc., Fiserv, Inc., JPMorgan Chase & Co., PNC Bank, N.A. and SAP America, Inc. over what appears to be claims of infringement due to the same ‘311 patent.
