I have some updated news (or maybe rumour) from a friend working at one of the biggest automobile companies in China. BYD almost confirmed they will not use any of Tesla's patents; their boss had said that in public that their own technology is more advanced. Certainly, I doubt what he said. May or may not be true, nevertheless, they couldn't deliver what they said so far. Geely top managements are mostly very excited the possibility to use Tesla patents. (Geely's owner called Elon Must as "God Man" in his personal blog.) They are having some big meetings recently to discuss about this particular project, the major discussion in the meetings is about the initial cost, and their ability to use or copy or improve Tesla patents. Current result seems to agree to create a new product line and development team and focus on a mid-price EV car; suppose similar and to be targeted on Tesla Gen3. They believe the range and quality may not as good as Gen3, but price should be about 1/3 lower compare to Gen3. Some of the more aggressive and ambitious managers even suggest to devote 1/3 or half of the cooperation's resource in Tesla patent related EV development. One special note, it seems most Chinese automobile makers aren't worry about the battery supply at all. Per their conclusion is that 18650 is widely available in China; quality varies, but really plenty of them. Many battery suppliers, large and small factories all can make plenty of them. "Because they are not trying to make EV car as perfect as, or better than, Model S. " A few other automobile companies already bought Model S for research purpose or "copy". What I mean copy, is not 100% copy, but copy some big selling points of and success of Model S. Especially after Tesla open the patents, they have nothing need to worry about how to copy. I believe we may see some cars from Chinese makers, using very big LCD display running Google or Apple CarPlay, or have frunk. In fact, they may have some cars more practical then Model S; likely within 2015. I love Tesla cars and all other EV cars; therefore, I will be very happy to see them pay big attention and resource in development of EV. All in all, I believe Elon Musk's open patent strategies indeed working, at least at China, EV development is really speeding up with turbo. This single step is like equal to 5 years of effort of EV development in China.
