Toshiba Files Lawsuit Against Katun, Says it Infringed on Toshiba Toner-Cartridge Patents

toshiba toner cartridgeToshiba America Business Solutions (TABS), together with co-plaintiff Toshiba TEC Corporation (TTEC), today reported it’s filed a patent-infringement lawsuit against Katun Corporation – a popular supplier of OEM-alternative toner and imaging supplies to office-equipment dealers – with Toshiba alleging that Katun’s OEM-alternative toner cartridges designed for use in Toshiba copier/MFPs infringed upon nine Toshiba U.S. toner patents. Toshiba filed the lawsuit in the United States District Court for the Central District of California on November 25th.

Toshiba says it’s filing the patent-infringement lawsuit against Katun to defend its intellectual property rights, while protecting its customers from infringing products claiming to be an alternative to Toshiba’s own products.

“TABS and TTEC have made substantial investments in their innovative and patented technology, which drives the reputation of Toshiba-branded products in the market as a go-to provider of reliable and trusted printing solutions,” said Tom Walter, TABS vice president of distribution and aftermarket sales at Toshiba America Business Solutions. “Despite numerous warnings from TABS and TTEC over the span of several years, Katun has continued to manufacture and sell products that infringe our patents. This lawsuit was a necessary response to Katun’s actions in the marketplace.”

Toshiba is not the only major copier/MFP company to file a toner-cartridge patent-infringement lawsuit against Katun. In May 2014, Canon Inc. filed a toner-cartridge lawsuit against Katun, along with many other OEM-alternative suppliers (see story here). The results of the Canon lawsuit are still pending.
