The FTC has been informally investigating chip maker Intel for the past two years because of complaints from competitor AMD that the company is violating anti-trust regulations. That investigation has recently been formalized in order to allow the FTC legal access to Intel documents that have been kept private pending litigation between AMD and Intel. That litigation isn’t expected to go to trial for another two years so the FTC formalized the issue in order to subpoena documents from both parties. Intel says that the company is doing nothing wrong and cites a recent drop in sales as evidence that competition in the industry is as strong as ever. In addition to the U.S. investigation, Intel faces similar charges in other parts of the world.
