I will point a couple:
- He says that contractors "by default" own the IP of the work they do for their employers. This is actually exactly the opposite: "work for hire" means that the employer owns the IP by default: http://contently.net/2013/07/09/find-work/work-made-for-hire...
- He glosses over / minimizes the fact that most of these "invention assignment" clauses are doomed in a court of law more often than not (even ignoring the states that outright prohibit them) if they do not fall within the scope of employment (sorry, I don't have a reference here, but I have heard of many such cases being thrown out in court)
As a business owner, he comes across as having a very clear agenda which is at odds with the reality of the law and the actual outcomes of these cases in court.
