5. How much does it cost to obtain a patent?

Do not be mislead, patents are not cheap! The PTO has established the following patent fees: For utility patents the filing fee for individual inventors (as opposed to corporations having 500 or more employees) is $515. If the patent is allowed, there is then an issue fee of $720. Commencing three and one half years after issue, the inventor must pay three periodic maintenance fees. For design patents the application fee is $220, the issue fee is $410, and there is no maintenance fee. The PTO fees are from time-to-time adjusted upward for inflation. The PTO fees are in addition to the fees charged by the patent attorney or agent for the preparation of the application, associated drawings, and amendments if required. Patent attorneys charge more for their services than do patent agents. Additionally, if the applicant desires a patent search (usually recommended) may be performed prior to application preparation and submission. The search cost can be as low as $500, but may be higher depending upon the complexity of the invention.
