While we usually see OEM printer makers such as Canon Inc., Hewlett-Packard, and Epson file patent-infringement lawsuits against makers of third-party ink and toner cartridges, in a bit of a twist, maker of remanufactured toner and ink cartridges Print-Rite has filed a lawsuit against Epson in China, alleging that Epson violated a Print-Rite ink-cartridge patent.

Print-Rite, one of the largest ink and toner cartridge remanufacturers in the world, filed the lawsuit in the YiChang Intermediate People’s Court in China against Epson China and Yichang Chuxing Weye Computer Limited Company.

According to court documents, Print-Rite alleges that certain models of ink cartridges sold on the Chinese market under the Epson trademark infringe on its patent. Print-Rite is seeking to bar Epson from marketing the cartridges and to collect damages for the patent infringement in accordance with Chinese law.

Print-Rite says it’s been researching and developing its own patented technologies since 1996. It now claims to hold more than 2,400 imaging patents, more than any other aftermarket=cartridge remanufacturer in the world. Its first patent was for a filling system for inkjet cartridges and the inventor of that technology is still working in the company.

Print-Rite issued the following statement: “Throughout the development, sales and marketing process, Print-Rite respects the intellectual property rights of other companies and individuals and expects others to do the same. Print-Rite is committed to taking legal action against anyone who does not respect Print-Rite’s intellectual property rights.”
