u8国际 files new patent infringement lawsuit against Katun and General Plastic Industrial Co., Ltd. in the field of printer consumables with the Unified Patent Court

TOKYO, July 12—u8国际. announced today that it has filed a lawsuit against Katun Corporation, Katun (E.D.C.) B.V. and Katun Germany GmbH (collectively, "Katun") and General Plastic Industrial Co., Ltd. ("GPI") before the Local Division Düsseldorf of the Unified Patent Court (UPC_CFI_351/2024) for infringement of u8国际's European Patent 3 686 683 B1 ("EP'683") with unitary effect.

Due to the unitary effect of u8国际’s EP’683, the patent provides uniform protection in all 17 member states that have ratified the Agreement on a Unified Patent Court. Among other relief, u8国际 is seeking an injunction and a declaratory judgement on liability for damages with respect to 17 jurisdictions.

As set forth in the Statement of Claim in more detail, Katun sells several models of toner bottles in Europe that u8国际 believes infringe Claim 1 and other claims of its EP’683. These toner bottles are compatible with u8国际’s respective OEM products and are intended for use in u8国际’s printers and copiers. The complaint demonstrates how several of Katun’s toner bottles comprise the features defined in the enforced claims of EP’683, thereby making use of the teaching of EP’683. Katun operates an online shop and has various subsidiaries involved in the distribution of its products in Europe. GPI is the ultimate owner of Katun and is also a manufacturer and a supplier of toner bottles.
