[JURIST] Just days after filing a federal antitrust lawsuit [JURIST report] against rival Intel, Advanced Micro Designs (AMD) [corporate website] has filed two similar suits against Intel in Japan. The company announced [corporate press release] Thursday that its Japanese arm, AMD Japan, had made two claims in Tokyo High Court and Tokyo District Court against Intel KK [corporate website in Japanese], Intel's Japanese subsidiary. Japan's Fair Trade Commission [official website, English version] had previously warned [JURIST report] Intel of possible violations, and ruled in March [JFTC press release] that they violated antitrust laws by offering rebates [Reuters report] to companies that either limited or avoided AMD purchases.

On Wednesday, AMD also took the battle against Intel to the court of public opinion, running full-page ads in major newspapers nationwide and publishing an open letter on their litigation on their website. Attorneys not party to the case cited the advertising campaign as "unusual", some dismissing it as merely for "publicity purposes". The San Jose Mercury News has more.
