Responding to an April lawsuit from Apple alleging breach of contract, Sorenson has filed a countersuit, the company announced today. The dispute stems from Sorenson’s license of its compression technology to Macromedia, which Apple claims it has exclusive rights to. “Apple’s lawsuit claims that Apple has exclusive rights to the very same things to which Mr. Jobs’ admits that Apple does not have exclusive rights,” Sorenson said, quoting a previous email from Steve Jobs that said Apple has exclusive rights to past versions of the technology, but not future ones.
