Costs for obtaining a patent

Obtaining a patent can be a costly enterprise. My hourly rate is $250/hour with a minimum fee ($5000) for preparing and filing a new U.S. patent application. In the table below I have summarized typical costs for preparing, filing, and prosecuting a new U.S. patent application, obtaining an issued patent, maintaining a patent in force after issue, patent searching, filing an international patent application, and managing foreign patent filings. For most new applications I require an advance deposit of at least $6000 before beginning work, and payment of any remaining balance of PTO and professional fees upon completion and prior to filing in the PTO. I provide written cost estimates before beginning work.
Effective 10/01/2023.  Please note: all fees are subject to change without notice.
