The Delhi High Court has restricted iBall from importing mobile handsets and other devices that infringe Ericsson?s registered patents. This comes after Ericsson had appealed against iBall on grounds that the company had not agreed to sign a license agreement on standard-essential patents, required for making mobile phones and other devices.

According to Ericsson, iBall has not entered into a licensing agreement under the Fair, Reasonable, and Non-Discriminatory (FRAND) norms, which cover patents on wireless technology standards such as GSM, EDGE and third generation. Meanwhile, iBall has argued that Ericsson had not provided enough information and therefore the suit could not proceed.

Ericsson had earlier filed a similar case against Micromax, in which the court had ordered the latter to pay royalty as an interim measure.
