I follow most Tesla items fairly closely. I think Elon Musk is perhaps the most interesting person on the planet. That said, I read a article last week that was saying the patent thing at this point was not much of a factor for folks.
The next big impact for Tesla might be the Gigafactory. A Gigafacory is a massive battery factory Telsa is building with Panasonic. It may drop the cost of batteries significantly.
