One of the big themes in Asia’s automaking industry this year has been a significant move by Japanese and Korean brands to join defensive patent alliances. It’s a strategic shift for the industry that in many ways is being led by companies in this part of the world, rather than their North American and European counterparts. But Chinese companies have not yet followed the same path in significant numbers, and industry observers say with litigation on the rise there, buy-in from players in China will be crucial for these alliances going forward.
