MOSCOW, April 10 - RAPSI. The Moscow Commercial Court has postponed the hearing of Wolta GmbH's lawsuit against the Russian Optkomplekt company over the illegal use of its registered Wolta brand, RAPSI reports from the courtroom on Wednesday.

The German company has asked the court to prevent Optkomplekt from using the brand. It also claims 163 million rubles ($5.2 million) in compensation from Optokomplekt and its partner Svet Expert.

Wolta earlier signed a license agreement with Svet Expert for the use of the brand, its representative said at the hearing. An inspection held in December revealed that Svet Expert has not been purchasing equipment directly from the plant in China, but from Optkomplekt, an intermediary.

Meanwhile, Wolta has not granted Optkomplekt the right to use the brand, the lawyer said. The plaintiff said this is a case of gray imports, as the products were imported into Russia without the copyright owner's permission, and the producer price remained undisclosed.

Meanwhile, Optkomplekt's lawyer said the plaintiff has not proved that the brand ownership has been infringed upon. Optkomplekt purchased the equipment from two Russian companies and resold it to Svet Expert in packages that were not marked with the disputed brand. The packages were branded by Svet Expert, which has been licensed to use the Wolta brand.

The lawyer also said one document presented by the plaintiff as evidence of the equipment delivery was a fake. He said Optkomplekt's director never signed the document.

Wolta is a German supplier of energy-saving equipment and original energy-saving solution. The company opened representative offices in Russia in 2005.
