The following general guidelines are merely estimates of prosecution costs. Your costs may, of course, vary. If you want a more specific estimate, please contact Quine Law describing your particular circumstances. An estimate is an estimate, and patent prosecution is notoriously unpredictable.

Filing a patent with the U.S. Patent and Trademark Office (PTO) generally runs from about $6000 to about $15,000 or more, including Patent Office fees, depending on the complexity of the case. At the Quine IP Law Group the draft application will normally include well formulated claims and supportive specification. We make an effort to provide broad support in the specification for claim amendments that may be necessary during prosecution of the case.

Prosecution of a patent generally comprises the tasks of responding to office actions from the PTO and various associated administrative tasks. Responding to an office action is expected to cost between about $2000 and $4000 or more, depending on the complexity. Over the course of several years, the total cost of pursuing a patent can range, e.g., from about $10,000 to $25,000 or more; including attorney and patent office fees, depending on the complexity and the particular Patent Examiner you may encounter.

The PTO usually does not send a first office action until at least 2 years after the application has been filed. Prosecution of an application typically takes from about 2 years to about 5 years from the filing date of the application. Currently, about half of all applications filed at the USPTO, ultimately result in an issued patent.

Finally, when a case is allowed, there are Patent Office Fees involved ranging from about $1200 to $2400. About half of applications are abandoned over insurmountable rejections, or lack of adequate financial resources to continue prosecution.

Quine Law is very experienced in filing Patent Cooperation Treaty foreign country applications and supervision of foreign prosecution. Should you desire to file sister applications in foreign jurisdictions, such as, e.g., Europe, China, Japan or Australia, we are the ready to serve you. Be aware that foreign patent prosecution is typically more expensive than it is in the U.S.


Our current billing rates are highly competitive due to our low overhead and flexibility to assign the right Attorney or Associate for each task, as required.

Deposit Fee: A deposit is generally required for initiation of representation for patent prosecution. Client account deposits for simple inventions can range as low as $5000 to about $10,000 for complex inventions. Additional retainers may be required as prior retainers are exhausted. Excess retainer fees are returned at completion or termination of services.
