Four leading companies have commenced a worldwide joint licensing programme for Blu-ray (BD) and DVD patents essential for BD products.

The patent licences from Mitsubishi Electric Corporation, Thomson Licensing, Toshiba Corporation and Warner Bros Home Entertainment (collectively, the "BD4C Licensing Group") are key to BD decoders, BD encoders, BD players, BD read-only discs, BD recordable discs, BD drives, BD/DVD hybrid discs, BD recorders and BD Products that incorporate DVD functionality, said a statement.

The potential licensees will benefit from one-stop shopping for the essential patents owned or controlled by the four companies, which will facilitate the development of the BD market.

The license portfolio consists of BD and DVD patents, owned or controlled by the four companies, that are essential for BD Products. Licenses for the portfolio will be available for products that comply with the specifications for the BD formats promulgated by the Blu-ray Disc Association.

Interested parties are also free to negotiate separate license agreements, rather than taking a single portfolio license, with each of the four companies, which have committed to provide such licenses for their respective essential patents under fair, reasonable and nondiscriminatory terms and conditions.

The companies have authorized Toshiba to act as licensor for the BD4C licensing group in licensing their essential BD patents for this joint licensing program. – TradeArabia News Service
