Hard-disk maker Cornice has filed a countersuit in response to a patent infringement lawsuit filed in June by rival hard-disk maker Seagate Technology.
Seagate's lawsuit alleged that Cornice's 1-inch Storage Element hard drives violate six of Seagate's patents covering a range of hard-disk technologies, including the guiding system for the actuator arm that scans the surface of the disk for data. The lawsuit seeks to prevent Cornice from selling the Storage Element drives in the US as well as unspecified monetary damages.
In July, Seagate took its claims of patent infringement to the US International Trade Commission, seeking to block the import of any device that contains a Storage Element hard drive.
Available in 1GB, 1.5GB and 2GB versions, Cornice's Storage Element hard-disk drives are found in several portable electronics devices including MP3 players from Sony, which uses them in its Aiwa brand players, Digital Networks' Rio brand audio products, and South Korea's iRiver and Digitalway.
Cornice's countersuit seeks a ruling by the US District Court for the District of Delaware that Seagate's patents are invalid, unenforceable, and not infringed by Cornice's products, the company said.
In addition, Cornice alleged that Seagate's lawsuit was baseless and constitutes unfair competition and tortious interference, entitling Cornice to damages from Seagate, it said.
The statement did not specify the amount that Cornice was seeking from Seagate in damages.
Cornice and Seagate could not immediately be reached for comment.
In addition to the allegations of patent infringement brought by Seagate, Cornice faces similar charges from another hard-disk maker, Western Digital.
In June, Western Digital filed a patent infringement lawsuit against Cornice in the US District Court for the District of Orange County in California. In that suit, Western Digital alleged that Cornice had infringed on seven of its patents related to hard-disk technology and was seeking monetary damages and a ruling that would prevent Cornice from infringing its patents.
