Trade body favors Samsung in patent dispute, says InterDigital

Wireless technology firm InterDigital received a blow in an ongoing patent infringement case with the US International Trade Commission's staff recommending in favor of South Korea's Samsung Electronics, a Reuters report said.

The news sent InterDigital's shares down as much as 28%, the report added.

In a statement, InterDigital said the US ITC staff recommended that Samsung, the world's No. 2 mobile handset maker, did not engage in unfair trade practices related to third-generation mobile technology.

InterDigital has maintained that Samsung engaged in unfair practices by selling certain 3G handsets and components in the United States that infringe five of InterDigital's patents.

Last week, InterDigital and Nokia agreed to drop patent cases in British courts against each other.
