Despite ongoing investigations in Korea and by the European Commission, the US Federal Trade Commission (FTC) won't conduct a formal anti-trust investigation into the world's biggest chip maker, Intel.

The New York Times reports that the commission has been conducting an informal review for more than a year following complaints from Intel rival AMD, but that its chairwoman, Deborah Majoras has rejected requests to escalate it into a formal investigation which would give staff members the authority to issue subpoenas and compel testimony from executives of the companies involved.
FTC officials say that two of the five commissioners recommended a formal investigation, but that Majoras declined, without elaborating, to authorise one.
Recently, regulators in Korea and with the EC have separately accused Intel of anti-trust violations by offering large discounts to computer makers in exchange for not using AMD products. The EC has given Intel until 4 January to answer the accusations.
The investigations are part of an ongoing legal, political and public relations battle between Intel and AMD over the $225-billion global chip market. AMD has also sued Intel in US federal court in Delaware where the trial is scheduled for mid-2009.
