Back in July, we reported that Matsushita had filed a lawsuit against CMC Magnetics, claiming that they infringed upon three of their DVD patents. According to an article at Reuters.com, Matsushita and CMC have settled their suit. As part of the settlement, the two companies have formed a cross licensing agreement, with CMC paying royalties to Matsushita for 10 years.
Panasonic maker Matsushita Electric Industrial Co. Ltd. and Taiwan's CMC Magnetics Corp. said on Monday they have reached a settlement on a DVD-related patent infringement lawsuit.
