Electronic giant Motorola Mobility's patent lawsuits have become the subject of two separate investigations by the European Commission.
The action comes after Apple and Microsoft both complained Motorola tried to block sales of their products.
Currently in the process of being taken over by fellow technology goliath Google, Motorola is accused of failing to license technologies on fair and reasonable terms.
This contravenes the Frand (Fair, reasonable and non-discriminatory) principles, which state that all technologies deemed to be essential to the market are made available at a free price to all competitors.
Motorola has, however, denied this and stated that it has always upheld the Frand obligations and complied with anti-trust laws that are in place.
The firm added it would be continuing to work with the European Commission to resolve this matter.
A commission statement read: “The commission will examine whether Motorola's behaviour amounts to an abuse of a dominant market position.”
