Roxio has responded to litigation commenced against it by Optima Technology, which could threaten all manufacturers in the CD-authoring business.

The legal action was revealed earlier this week. It asserts that Roxio is infringing Optima's patent for a "Recordable CDROM Accessing System," software that enables users to burn photographs, music, video and data onto recordable CD's. Optima is seeking unspecified damages, royalties and legal fees from Roxio.

Optima Technology's legal brief, Robert Lyon said: "Companies like Roxio, selling or using the software that Optima wrote, without a license from Optima, shall be required to compensate them for their lost revenues. Optima believes most every company in the CD burner industry may be infringing."

Roxio's response follows: "We are aware of the Optima patent and the claims within and believe that any claim of infringement by Roxio's software products is utterly without merit.

"At Roxio, we respect the legitimate intellectual property rights of others but in this instance there is no colourable argument that the claims set forth in the patent read on any Roxio products."

It presently appears the case will go to court. Roxio said: "We intend to aggressively defend ourselves in this litigation."
