Creative Technology plans to pursue other MP3 player and music phone manufacturers to protect its Zen user interface patent, following its $100 million settlement with Apple.

Creative spokesman Phil O'Shaughnessy confirmed the company's intentions this week, speaking to Dow Jones. "As the patent covers the hierarchical user interface on portable media players, many manufacturers are using the Zen patent today," he said.

The spokesman observed that the company is open to reaching "amicable solutions" with any company using the patented technology, which governs a menu-based user interface for media devices.

Discussing the company's decision to pursue the patent against other firms, IDC analyst Claudio Checchia stressed the need for an amicable settlement: "I think it has been acknowledged that Creative was there first, so they won the patent - so their rights have been recognised. If they are going to go after other manufacturers, it really depends on what they goal is, and the problem with these lawsuits is that they can be quite expensive."
