Design Patent - $2,400*Design patents protect the appearance of an invention. They last 14 years and do not require the payment of any maintenance fees. Design patents, however, are of limited value as they are usually very easy to design around.
* Small entity, e.g. less than 500 employees - add $630 for a large entity. Payment schedule: 50% upfront and 50% upon receiving a Notice of Allowance. If I don't get your patent application allowed, you don't pay that last 50% amount. |
