The Tokyo District Court ruled Friday that evidence collected by the Fair Trade Commission of Japan (JFTC) as part of a year-long investigation into Intel's business practices in Japan should be disclosed, Advanced Micro Devices claims.

The court ruling was made at a hearing related to two lawsuits filed in June this year by AMD's Japanese subsidiary against Intel's Japanese unit. AMD, Intel's rival in the computer processor market, intends to use the evidence as part of its case that alleges Intel violated Japan's Antimonopoly Act, it said in a statement.

The Japan lawsuit was filed days after AMD hit Intel with a broad antitrust suit in the US and came three months after the JFTC found Intel had abused its monopoly power in the Japanese microprocessor market, substantially restraining competition. Intel disagreed with the findings but didn't officially challenge them and pledged to refrain from several types of business practices.

AMD is seeking damages of $50 million in the Tokyo High Court and "millions of dollars in damages" in Tokyo District Court for "various anticompetitive acts" by Intel, it said at the time of the filings.

Intel could not immediately be reached for comment.
