Bedford’s iRobot Corp. said Friday that it has obtained preliminary injunctions from a German court over allegations that two related Chinese companies have infringed on four German patents that cover technology that iRobot developed for its Roomba vacuum-cleaning robots.

The Chinese companies are Shenzhen Silver Star Intelligent Technology Co. Ltd. and Shenzhen Silver Star Intelligent Electronic Ltd. Shenzhen Silver Star can appeal the court’s decision. An attempt to reach Shenzhen Silver Star was not immediately successful.

The preliminary injunctions were served on Shenzhen Silver Star and infringing goods were seized from the company today at IFA, a trade show for consumer electronics and home appliances in Berlin, iRobot said in a press release.

Shenzhen Silver Star manufactures vacuum-cleaning robots in China that are sold under various brand names in Europe.

In a statement, iRobot chairman and chief executive Colin Angle said: “IRobot has made significant investments to protect its intellectual property. The company has sold more than 10 million home robots worldwide and intends to protect its global patent portfolio by the appropriate means available domestically and abroad.”

The company does not specifically break out Roomba sales, but says that the majority of its home robot sales are of the Roomba.
