Toshiba Files Patent Infringement Lawsuit Against Katun

IRVINE, Calif. (Dec. 2, 2015) — Toshiba America Business Solutions (TABS), together with co-plaintiff Toshiba TEC Corporation (TTEC), has filed a patent infringement lawsuit against Katun Corporation (Katun) in the United States District Court for the Central District of California.  The lawsuit, filed on Nov. 25, alleges Katun’s infringement of nine United States patents co-owned by TABS and TTEC related to toner cartridges used in Toshiba-branded multifunction products.   

Toshiba is filing a patent infringement lawsuit against Katun to defend its valuable intellectual property rights while protecting its customers from infringing products claiming to be an alternative to Toshiba’s own high-quality 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.”
