Does someone offer a comprehensive "Patent it yourself" course? This would be very useful, not necessarily to actually write patents but rather to truly understand the subject. It could save entrepreneurs time and money and, yes, some could actually use the knowledge to write their own patents. Patents are very expensive. The small entrepreneur often has to choose between protecting IP and having cash to run the business. Spending $15K to $25K on a patent is out of the question for most small businesses. In that context, the idea of writing multiple patents is nothing less than fantasy. Such a course, if well done, could easily be worth a few thousand dollars. It would also help equalize the disparity of IP "power" between large corporations and the little guy. When someone has the financials to write hundreds of patents per year, while the other side can barely (financially) approach one every five years, that creates a serious asymmetry that is hard to resolve.
