A group of lawyers, researchers and software experts are taking aim at companies who hold patents the group claim are too sweeping.

The Electronic Frontier Foundation is seeking to overturn 10 patents they claim are too sweeping, the New York Times reported on Monday.

The foundation, which includes lawyers, researchers and software experts, takes aim at the patents of several little-known companies, but names two media and entertainment leaders: Clear Channel Communications Inc., the No. 1 U.S. radio station owner, and video-game maker Nintendo Co. Ltd. according to the article.

Clear Channel’s intellectual property includes method of distributing concert recordings, while Nintendo has the rights to some platform software for hand-held games, according to the article.

The report said the list of targets was drawn from 200 submission solicited through a Web site operated by San Francisco-based EFF.

Other targets of the lawsuit include Acacia Research, which has a patent on systems that transmit and receive “digital content over the Internet, cable, satellite and other means,” according to the report.

Test Central, a company that holds patents on online testing, is also in the group’s cross-hairs.
