The governmental fees are about $1,500. The attorney fees will vary quite a bit depending upon the complexity of the invention and the skill of the attorney. While the lowest cost patent attorney will likely get you a bad patent, the highest cost patent attorney will not necessarily get you the best patent. For a simple invention, you can figure on paying a total of about $9K-$10K over the next three years. You might pay more or less depending upon how many similar devices the Patent Office finds are already out there. If you get quoted less than that by a patent attorney, I would question whether you are being quoted all of the anticipated fees and/or the skill and experience of the patent attorney.
