MOSCOW, August 31 - RAPSI, Sergei Feklyunin. The Ninth Commercial Court of Appeals has held in favor of the Moscow Commercial Court, which prohibited Yandex from using Mikhail Lvov's Dictionary of Antonyms, the court told the Russian Legal Information Agency (RAPSI).

The court has dismissed Yandexs appeal against the first-instance court.

The Moscow Commercial Court prohibited Yandex from using the dictionary under a lawsuit filed by AST-Press Kniga in June. The court recovered 500,000 rubles (roughly $17,854) from Yandex for violating reproduction rights.

AST-Press Kniga told RAPSI that Yandex illegally posted on its website the Dictionary of Antonyms, which AST-Press Kniga published in 2008.

The publishing house entered into an agreement with Lvov in 2002.

AST-Press was founded in 1990. The holding comprises a network of publishing and trade organizations, according to the companys website.

Yandex is a major Russian search engine.
