Patent Cost Calculator


Calculating the cost of filing a patent is an essential step for inventors and businesses looking to protect their intellectual property. Whether you are applying for a utility patent or a design patent, understanding the associated fees is crucial for budgeting and decision-making. In this article, we provide a simple Patent Cost Calculator to help you estimate the total cost of patent filing.


The formula for calculating the total patent cost is straightforward:

Total Cost = Filing Fee + Attorney Fee + Additional Patent Type Cost

  • Filing Fee: The fee required to submit your patent application to the relevant patent office.
  • Attorney Fee: The cost of hiring a patent attorney to assist you throughout the patent application process.
  • Additional Patent Type Cost: Depending on the type of patent (utility or design), there may be additional costs associated with the application.

How to Use

  1. Select the type of patent you are applying for from the dropdown menu (Utility Patent or Design Patent).
  2. Enter the filing fee, which is the fee required by the patent office to process your application.
  3. Enter the attorney fee, which is the cost of hiring a patent attorney to guide you through the process.
  4. Click the “Calculate” button to determine the total cost of your patent application.


Let’s say you are applying for a Utility Patent, and the filing fee is $5000, and your attorney charges $3000 for their services. After clicking “Calculate,” the total cost would be calculated as follows:

Total Cost = $5000 (Filing Fee) + $3000 (Attorney Fee) + $1500 (Additional Utility Patent Cost) = $9500

The estimated total cost of your Utility Patent application would be $9500.
