Linex Technologies has filed suit against the makers of several technology companies, accusing them of violating patents it owns on wireless communications.

Hewlett-Packard, Apple, Aruba Networks, Meru Networks, and Ruckus Wireless are listed in the complaint filed with the International Trade Commission on May 6. Linex has asked the commission to ban the import of offending products. Among the products listed are HP's Pavilion and Envy laptops, Apple's MacBook, MacBook Air, MacBook Pro, Airport Extreme, and Time Capsule.

Linex, a Florida company that licenses wireless technologies, also filed a lawsuit in the U.S. District Court in the District of Delaware against the same companies. In that suit it is asking for monetary damages for the violation of its patents.

The patents concern space diversity and coding, spread-spectrum antenna and method, which uses multiple transmitter antennas and multiple receiving antennas to improve a signal's reliability, and multiple-input multiple-output spread spectrum system and method, which uses multiple antennas to maximize a wireless signal indoors.
