Epson U.S. Printer Cartridge Patents

Seiko Epson Corporation believes that the following products, or components of the following products, may be covered by one or more of the indicated U.S. patents in the United States and, by reference to this web page, are marked pursuant to 35 U.S.C. § 287. However, the absence of a patent number associated with a product does not necessarily mean that the product is not covered by a particular patent either listed or not listed below. Furthermore, the omission of a product from this chart does not necessarily indicate that such product is not covered by a patent either listed or not listed below. Products remanufactured by Epson that retain their original Epson components have exhausted their patent coverage upon their first sale by Epson.
