Burst.com announced today that it had reached a mutual agreement with Apple to postpone the original February 17 deadline for a response to Apple's complaint until March 20. Burst, a provider of media delivery technology, was sued in U.S. District Court in San Francisco on January 4 by Apple for declaratory relief, alleging patent invalidity or non-infringement. The suit followed a break-down in protracted negotiations for issuance of a license of Burst's patents to cover Apple’s iPod and iTunes products. Since a $60 million Microsoft settlement, the company has been in patent licensing discussions with several companies engaged in the distribution of audio and video content on computer networks.
