Here is a link to Tesla's 'thoughts' on open source patents to speed development of battery technology. I wonder if Apple will be thinking the same, probably not:

'Technology leadership is not defined by patents, which history has repeatedly shown to be small protection indeed against a determined competitor, but rather by the ability of a company to attract and motivate the world’s most talented engineers. We believe that applying the open source philosophy to our patents will strengthen rather than diminish Tesla’s position in this regard.'

As Musk said today, the same applies to their powerwall technologies.
