Macrovision sues Altiris, claiming patent breaches

Macrovision Corp., a Santa Clara, Calif.-based maker of software to prevent copying of digital music and DVDs, sued Altiris Inc., claiming infringement of two patents covering a system for managing product licenses.

In a complaint filed Tuesday in federal court in San Jose, Macrovision asked for a court order blocking Altiris from using its patented technology without permission. Macrovision is also seeking monetary damages.

Macrovision said it feared that Altiris was planning to sue it over an Altiris patent and asked for a court order declaring that it was not in violation of the patent.

A spokesman for Lindon, Utah-based Altiris did not return a call seeking comment.
