Patents can often be worked around. Almost all "real" patents can be worked around (BS "business method" patents are not "real" patents by my definition).
I also think Tesla has a bright future. But I hope they're relying on their brand value rather than transient advantages like patents. If I hear from Musk that he thinks their patents are going to be competitive advantage, I will be factor that (negatively) in my opinion of the company's prospects.
