What does it cost to file and prosecute a patent?
Typically, the cost of preparing (filing) a patent will be between $6,000 to $9,000 depending on the complexity of the application. Prosecution of the application (the process of shepherding the application thru various stages of the patent review process prior to issuance) will increase the total cost between $13,000 to $25,000. Foreign patents can be extremely expensive, often in excess of $100,000 to $150,000 from filing to issue depending on the country.
