Samsung’s patent deals are being looked into by the European Commission.
Competition regulators are investigating whether the firm used some of its intellectual property rights to “distort competition in European mobile device markets”.
The commission says it wants to know if Samsung has failed to live up to a commitment to license key technologies to rivals.
The action comes as the company is involved in patent battles with Apple.
A statement by the South Korean firm said: “Samsung Electronics has not received any formal notice and is unable to discuss the matter at this time.”
The inquiry centres on Frand commitments – a promise by industry players to license innovations that are essential to an industry standard on fair, reasonable and non-discriminatory terms.
This means that the owner cannot discriminate who gets to use its invention and that its fee cannot be excessive.
The commission notes that in 1998 Samsung offered an “irrevocable commitment” to the European Telecommunications Standards Institute to respect Frand terms.
But the regulator says that: “In 2011, Samsung sought injunctive relief in various member states against competing mobile device makers based on alleged infringements of certain of its patent rights which it has declared essential to implement European telephony standards.”
