The technology sector got more than its share of attention on the equities markets on Tuesday as Advanced Micro Devices announced that it has filed a lawsuit against Intel.

The suit charges that Intel forced clients to buy their chips rather than AMD’s product.

While two investigations by the US Federal Trade Commission have been closed without finding any wrongdoing on Intel‘s part, AMD has filed a complaint of anti-competitive practices by Intel to the European Commission.

A ruling by the Fair Trade Commission in Japan found that Intel had violated anti-trust laws when it offered rebates to five Japanese companies if they would limit purchases of chips made by AMD.

After news of the lawsuit was released, AMD’s shares gained 6.3 percent to $17.70, and Intel’s stock were up by 1.8 percent to $26.33.
