Depending on the complexity, writing and filing a patent application may cost roughly $8,000 to $15,000. Additional costs are incurred as the patent office reviews the application (the patent prosecution process) and even after the patent issues so that a single US patent, over its lifetime, may cost on the order of $30,000 and often more.
