Costs for obtaining a patent

Obtaining a patent can be a costly enterprise. My hourly rate for new clients is $200/hour with a minimum fee for preparing and filing a new U.S. patent application (provisional - $4000; non-provisional - $5000). 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 $5000 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 01/01/2016.  Please note: all fees are subject to change without notice.
