U.S. chipmaker Nvidia has sued EU antitrust regulators for accepting an Italian request last year to scrutinise its acquisition of AI startup Run:ai, saying they had flouted an earlier court ruling restricting their merger powers on minor deals.

Nvidia (NVDA) has filed a suit against a European Union regulator over what it views was an unnecessary probe into Nvidia's acquisition of Run:ai last year, according to Reuters.

The US company argues that the Commission disregarded a prior court ruling that limited its ability to review minor mergers.
