I was thinking of patenting the device I designed and built last semester for a graduate school project. I talked to a professor who has experience applying for patents, and he tells me that it costs on the order of $10,000 to obtain a patent and even more to try to enforce it. I get the impression that the patent process is heads-I-win-tails-you-lose. If nobody attempts to exploit your idea, it's probably because there isn't much of a market for it. If there is a big market for it, several entities will exploit your idea, and they will have deeper pockets for legal battles against you.
So when does it make sense to file for a patent? In case you are wondering, my device is a better SWR/wattmeter. It doesn't involve any exotic physical or chemical principles - it's something I decided to create because of shortcomings in existing designs that I thought could be overcome. The most it can do is take the world of amateur radio world by storm. It won't make me the next Bill Gates.
Should I file for the patent? Or is it too much time and money for too dubious a benefit?
