Following the lead of foreign regulators, New York's attorney general, Andrew M. Cuomo, filed a federal antitrust lawsuit Wednesday against Intel, the world's largest chip maker.

The lawsuit charges that Intel violated state and federal laws by abusing its dominant position in the chip market to keep its main rival, Advanced Micro Devices, at bay. Intel has faced similar lawsuits in Asia and Europe, and in May the European Commission fined the company a record $1.45 billion for antitrust violations.
