JAPAN (From news reports) -- Nippon Paper Crecia has filed a lawsuit against Daio Paper for an alleged infringement of its patents for toilet paper with rolls three times as long as conventional products.
In the suit, filed with Tokyo District Court, Nippon Paper Crecia demands that Daio stop making and selling similar products and pay ¥33 million in damages, the subsidiary of Nippon Paper Industries said Tuesday.
Nippon Paper Crecia believes that Daio's toilet rolls 3.2 times longer than conventional products, sold under the Elleair brand, infringe its three patents for making its Scottie-brand threefold toilet paper more durable and softer than conventional products.
Following talks with Nippon Paper Crecia, some other makers that had released similar products agreed to stop production and sales of the items in question, according to the parent company.
But the subsidiary's negotiations with Daio failed to reach any solution.
A Daio official declined to comment, saying that the company has not received a written complaint.
