I'm a non-american individual who wants to apply for patent in USA. My invention is related to energy generation. How much will it cost?

Why is working with a patent attorney so expensive? Will applying for the patent myself reduce the cost? What would be the cost?

  • You don't need a U.S. attorney. It's better to work with a patent agent locally. Beside cost in term of $, you should also consider the cost in term of time. Patent examination takes time. If you file your own patent, your unfamiliarity with the process can delay the patent grant, before which you are totally unprotected.

It’s impossible to give an adequate quote and set of options without detail about how the technology works and a better sense of your business plan moving forward. The variety of options is extremely large. The cost to draft and file a patent application could be from $500 - $30,000 (US) depending on a variety of factors.

You should talk with a patent attorney about your options and the costs. Drafting and/or filing the application yourself would reduce costs, but is not advisable if you want viable protection.

Also, you might find the following resources helpful when comparing patent attorneys and quotes for patent applications:
