What is the cost of filing a patent application?

The cost of filing a patent application with the US Patent and Trade Office (USPTO) varies based on several factors. For a basic utility patent application, the filing fee ranges from $70 to $280, depending on the size of the entity. However, additional fees might apply, such as the examination fee and search fee, which range from $120 to $480. Legal assistance or patent attorney fees can add to the cost, as their services are not included in the USPTO filing fees. To receive accurate and up-to-date information on the total cost, it is recommended to consult the USPTO's official fee schedule or seek guidance from a patent professional.
