Demands injunction against iTunes, iPods.

Four months after Apple Computer asked the courts to dismiss its patent claims, has filed a patent infringement lawsuit demanding an injunction against the iTunes Music Store, iPod devices, and other Apple software.

Burst’s software aids in the delivery of audio and video files over networks. The company claims it’s technology has been “essential to Apple’s success,” according to a statement.

Of the four patents listed in the suit, three were named in a similar suit against Microsoft. Microsoft settled that lawsuit by agreeing to pay Burst $60 million for a nonexclusive license in March of last year.

Burst had been negotiating with Apple to agree upon a similar licensing agreement over the course of last year. But in January, Apple filed for a declaratory judgment stating it is not infringing on any Burst patent and that now licensing structure is necessary.
