Symantec has sued Microsoft accusing it of having stolen its data storage techniques:
As part of the complaint, the security software maker has asked the federal court to issue an injunction stopping further development on Microsoft's next operating system – Vista.
Microsoft is alleged to have “misappropriated” features from 'Volume Manager' a security software made by Symantec. This software enhances PC's capacity to store and manage great amounts of data. The technology was developed by Veritas Software which Symantec acquired for $13.5bn last year. It was licensed to Microsoft for use in its Windows 2000 operating system and Veritas reserved the exclusive right to develop and sell more advanced products for the O/S. However, Microsoft built some of those advanced features into its next O/S – Vista, infringing the contractual provision that reserved the right with Veritas.
