An overview of a patent application and maintenance process
Determine the type of Intellectual Property protection that you need
To protect your invention, you may need a patent, trademark, copyright, marketing plan, trade secrets, or some combination of these. Before you begin preparing a patent application, find out if you really need a patent or some other form of Intellectual Property protection.
Determine if your invention is patentable
To determine if you can patent your invention, you will need to know the answers to a few simple questions. Go to our Patent FAQ page and enter these questions to learn more about the Patent Process -
- Who can apply for a patent?
- What can and cannot be patented?
- How do I know if my invention is patentable?
- How long does patent protection last?
- How much does it cost to get a patent?
Search to see if your invention has already been publicly disclosed
- You cannot get a patent if your invention has already been publicly disclosed. Therefore, a search of all previous public disclosures should be conducted. A search of foreign patents and printed publications should also be conducted.
If you are not experienced at performing patent searches, a registered attorney or agent is recommended.
- Attorneys and agents with licenses to practice before the USPTO
- Are you an inventor or small business who has limited resources and needs help applying for a patent on an invention? If so, you may be eligible to receive pro bono (“for free”) attorney representation through either the Law School Clinic Program or the Patent Pro Bono Program. Additionally, the USPTO maintains several other legal assistance resources and programs for independent inventors, entrepreneurs, and small businesses.

What kind of patent do you need?
There are three types of patents - Utility, Design, and Plant.
Utility patents may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or compositions of matters, or any new useful improvement thereof. By far, most patent applications filed at the USPTO are utility applications.
- Applying for a Utility Patent
- Maintaining your Utility Patent
- Biotechnical Sequence listing Validation and Authoring tools
- Business Method Patent issues
Design patents may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.

Plant patents may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant.
Get ready to apply
Once you have determined the type of Patent that you need, you can consider your application strategy and whether to use professional legal services.
How much is this going to cost?
A patent application is subject to the payment of a basic fee and additional fees that include a search fee, an examination fee, and issue fee. Depending on your application, there may also be excess claims fees.
- Fees vary depending on the type of patent application that you submit
- Additional $200 fee for small entity applications if they are filed by mail or hand-delivery
- Current Fee Schedule
- For Information on Fees under AIA and Prioritized examination go to our AIA FAQ page and filter on "Fees"
How long will this take?
Estimate how long it will be until you receive your first letter from the USPTO in response to your application.
See the Patents Data Visualization Center for an overall average First Office Action estimate and Total Pendency.
Consider expedited examination options. The USPTO Patent Application Initiatives Timeline displays various programs and initiatives that are available to applicants during each phase of the application process. Each program is designed to advance the progress of a patent application and to provide applicant assistance. View a detailed Matrix of programs available Prior to Examination.
Do you need International protection?
- International Patent Legal Administration (formerly PCT Legal)
- Filing a new International Application under the Patent Cooperation Treaty (PCT)
Do you want to file a Provisional or Nonprovisional application?
- Utility and Plant patent applications can be filled using either a provisional or nonprovisional application. A provisional application is a quick and inexpensive way for inventors to establish a U.S. filing date for their invention which can be claimed in a later filed nonprovisional application.
- Provisional Patent Application
Should you hire a Patent Attorney or Agent?
The preparation of an application for patent and the conducting of the proceedings in the United States Patent and Trademark Office (USPTO or Office) to obtain the patent is an undertaking requiring the knowledge of patent law and rules and Office practice and procedures, as well as knowledge of the scientific or technical matters involved in the particular invention.
Inventors may prepare their own applications and file them in the USPTO and conduct the proceedings themselves, but unless they are familiar with these matters or study them in detail, they may get into considerable difficulty. While a patent may be obtained in many cases by persons not skilled in this work, there would be no assurance that the patent obtained would adequately protect the particular invention.
Most inventors employ the services of registered patent attorneys or patent agents

Work with your examiner
If your application is incomplete, you will be notified of the deficiencies by an official letter from the USPTO, known as an Office Action. You will be given a time period to complete the application filing (a surcharge may be required). If the omission is not corrected within a specified time period, the application will be returned or otherwise disposed of; the filing fee if submitted will be refunded less a handling fee as set forth in the fee schedule. Learn more about responding to Office Actions.
Estimate how long it will be until you receive your first official correspondence from the USPTO in response to your application.
Once your application has been accepted as complete, it will be assigned for examination.
Your examiner will review the contents of the application to determine if the application meets the requirements of 35 U.S.C. 111(a).
- If the examiner does not think your application meets the requirements, the examiner will explain the reason(s). You will have opportunities to make amendments or argue against the examiner's objections.
- If you fail to respond to the examiner's requisition, within the required time, your application will be abandoned.
If your application is twice rejected, you may appeal the examiner's decision to the Patent Trial and Appeal Board (PTAB)
- If your response to a Final Action does not overcome all of the examiner's objections or if any of the claims have been twice rejected.You can consider filing an appeal with the Patent Trial and Appeal Board (PTAB)
If you have chosen legal representation, remember that once an application is filed by a patent attorney or agent, the USPTO will only communicate with the attorney or agent. Inventors often call the USPTO for updates, but they have a designated attorney or agent representing them. The USPTO does not engage in double correspondence with an applicant and a patent practitioner (37 CFR 1.33).
Sign up to view your pending application and documents in Private PAIR. You can also sign up for the PAIR e-Office Action Program to receive an email notification when a new Office communication is available for viewing and download in PAIR.
Consider an Interview with your examiner - The USPTO encourages examiners to take a proactive approach to examination by reaching out and engaging our stakeholders in an effort to resolve issues and shorten prosecution.

Receive your approval
If the examiner determines that your application is in satisfactory condition and meets the requirements, you will receive a Notice of Allowance.
- The notice of allowance will list the issue fee and may also include the publication fee that must be paid prior to the Patent being issued.
- Frequently asked Questions about the Notice of Allowance and the Issue fee.
- Patent Fee Table - Issuance Fees
Utility and reissue patents are issued within about four weeks after the issue fee and any required publication fee are received in the Office. A patent number and issue date will be assigned to an application and an Issue Notification will be mailed after the issue fee has been paid and processed by the USPTO.
The patent grant is mailed on the issue date of the patent. It includes any references to prior patents, the inventor(s)') names, specification, and claims (to name a few). It is bound in an attractive cover and includes a gold seal and red ribbon on the cover.
Order certified documents - Order certified documents with the USPTO ribbon and seal as well as the signature of an authorized certifying officer.
Maintain your patent
Pay Maintenance Fees and Check the Status
Maintenance fees are required to maintain a patent in force beyond 4, 8, and 12 years after the issue date for utility and reissue utility patents. If the maintenance fee and any applicable surcharge are not paid in a timely manner, the patent will expire.
- See the Maintain Your Patent page for more information.
