First question clients often ask is: How much does it cost to file a patent application?

The cost to file a patent application can vary depending on whether you are filing a provisional patent application or a regular patent application. Provisional patent applications have less stringent requirements and lower filing costs than a regular patent application. Filing a simple provisional patent can cost under $1,000. The cost to prepare and file a regular patent application is typically greater than $6,000. The majority of the cost for the regular patent application is professional time for drafting the patent application.

The initial regular patent application can be filed in additional English-speaking countries for $1,500 to $2,500 or as an international patent application for $4,000. The initial patent application can be filed with the European Patent Office for $6,000 to $7,000, which is much higher but includes multiple European countries. Filing in non-English language countries can be expensive due to the high cost of technical translations and typically ranges from $5,000 to $7,000 per country.
