The US has announced a shift in anti-monopoly policy that could lead to closer scrutiny of the business operations of technology giants like Google, Intel and Oracle.
Later this week, the European Commission is expected to announce a substantial fine against Intel over charges that the company unlawfully provided rebates and price reductions to customers.
Christine Varney, head of the Justice Department's anti-trust division, has signalled a new aggressive approach to anti-competitive practices in the US, according to the New York Times.
In a speech to the Center for American Progress, Varney announced a new enforcement policy that reverses the Bush administration's approach of favouring defendants against anti-trust claims.
Varney said: "The Bush administration policy lost sight of an ultimate goal of antitrust laws - the protection of consumer welfare."
The policy shift could see an increase in anti-competitive investigations against bigger tech companies that will help level the playing field for smaller companies, according to US media reports.
