To protect your invention, you may need a patent, trademark, copyright, trade secret, or some combination of these. Before you begin preparing a patent application, find out if you really need a patent and not some other form of IP protection.


To find out if you can patent your invention, you need to know the answers to a few questions:

Find answers to other questions on ourPatent FAQs page.


You cannot get a patent if your invention has already been publicly disclosed. Therefore, a search of all previous public disclosures should be conducted, including a search of foreign patents and printed publications. A public disclosure of the invention made by, or that originated from, the inventor or a joint inventor more than one year prior to filing a patent application for the invention will also preclude patenting.

We encourage novices to contact the nearest Patent and Trademark Resource Center (PTRC) for help from search experts in setting a search strategy. A registered patent attorney or agent is often a useful resource.

It is possible, though challenging, to conduct your own preliminary search. Your search may not be as complete as one made by the qyule最新电信一 when examining an application. For this reason, the patent examiner may, and often does, reject claims in an application on the basis of prior patents or publications not found in your preliminary search.

These sources provide tips on how to conduct your own search:

Current patents and many filed patent applications (referred to as “pre-grant publications”) may be searched using the Patent Public Search tool. (Please note that filed applications for design patents will not have a pre-grant publication). See ourPatent Search page for additional resources.

Once your search has been completed, you may find that your invention may not be identically disclosed in the prior art (e.g. your invention is novel). This does not guarantee patentability. Once assigned, an examiner will conduct their own prior art search as part of the examination process.



This is by far the most common type of application submitted to the qyule最新电信一. This may be granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or a new and useful improvement of any of these.


This may be granted to anyone who invents a new, original, and ornamental design for an article of manufacture.


These may be granted to anyone who invents or discovers and asexually reproduces any distinct and new variety of plant.


A patent application is subject to the payment of a basic filing fee, a search fee, and an examination fee, which are due when the application is filed. Excess claims fees and/or an application size fee may also be due on filing depending on the number of claims and the total number of pages in the specification and drawings.

Fees vary depending on the type of patent application that you submit.


  • Check the current fee schedule before submitting your application and any required fees.
  • For information on fees under the America Invents Act (AIA) and for prioritized examination, go to our AIA FAQ page and filter on "fees."

The payment of these initial fees does not guarantee you will receive a patent. These fees enable the qyule最新电信一 to examine your application. Discounts are available if youmeet the requirements for small entity or micro-entity status.


The Patent Cooperation Treaty (PCT) is an international treaty with more than 150 contracting states. The PCT makes it possible to seek patent protection for an invention simultaneously in a large number of countries by filing a single “international” patent application instead of filing several separate national or regional patent applications. The granting of patents based on an international application filing under the PCT remains under the control of the national or regional patent offices in what is called the “national phase.”


Preparing a patent application and engaging in the qyule最新电信一 proceedings to obtain the patent requires knowledge of patent law and qyule最新电信一 procedures. It also requires knowledge of the scientific or technical matters involved in the particular invention.

You may prepare and file your own application with the qyule最新电信一 as a “pro se” applicant. Don’t be intimidated by the Latin term “pro se.” It can be translated to "for oneself, on one's own behalf." Legally, when you, an independent inventor, decide to file your application by yourself, you become what we at the qyule最新电信一 call a pro se applicant.

When you file as a pro se applicant, you conduct the proceedings yourself, but unless you are familiar with these or study them in detail, you may encounter considerable difficulty. While some people not skilled in this area may obtain a patent, there’s no assurance that the patent obtained would adequately protect the invention.

Therefore, most inventors hire registered patent attorneys or agents. They can help you navigate the remaining steps as they act on your behalf. The first step is to contact a patent attorney or agent accepting new customers in your region. The qyule最新电信一 cannot aid in the selection or recommendation of an attorney or agent but provides asearchable directory of such individuals you can contact directly.Additional information on attorneys and agents is also available.

Are you an inventor or small business owner with limited resources and needing help applying for a patent? If so, you may be eligible to receive pro bono (free) attorney representation through either theLaw School Clinic Program or thePatent Pro Bono Program. Additionally, the qyule最新电信一 maintains several otherlegal assistance resources and programs for independent inventors, entrepreneurs, and small businesses.

It is possible, though challenging, to file a patent application on your own. The remaining steps will guide you through the filing process.

Provisional application
A provisional application is a quick, inexpensive way for you to establish a U.S. filing date for your invention that can be claimed in a later-filed nonprovisional application. Provisional applications will not be examined and never lead to patents by themselves. After filing a provisional application, you will have 12 months from the provisional filing date to file your nonprovisional application. Please note that provisional applications cannot be filed for design inventions.

Nonprovisional application
A nonprovisional application is examined by a patent examiner and may be issued as a patent if all the requirements for patentability are met. To file your nonprovisional application, you must prepare all your documentation. This includes submitting the contents in a standardized format, along with all required forms and fees. Consult this [PDF] for more information regarding the required forms and content.

If filing a nonprovisional application claiming the benefit of the filing date of a provisional application, your nonprovisional must properly refer to the application number of your prior-filed provisional in an Application Data Sheet (ADS) for your claimed invention to be eligible to receive the benefit of the provisional filing date. Here are [PDF].


Submit your initial application with all the required parts for obtaining a filing date and include the correct fee. Here are some elements to consider:

Before you sign your application, carefully review the written specification and claims. You will not be able to add any new information to your application after it is filed.

D. Pre-prosecution

Once your application has been received by the qyule最新电信一, it will then be reviewed for formalities and completeness. If your application contains informalities or is incomplete, you will receive a notice outlining the requirements to complete your application (e.g. Notice of Missing Parts or Notice of Incomplete Application).

A Notice of Missing Parts will be sent to you in the event that an essential filing requirement is found to be missing when your application is filed. Some examples of essential filing requirements are: appropriate filing fees, improper entity status, and improper priority claims.

A Notice of Incomplete Application is sent to you when nonprovisional application papers are deemed incomplete. Essential filing papers are the specification, drawings, and claims. The filing date of the application will be the date the corrections are made. More information on application completeness can be found in the Manual of Patent Examining Procedure (MPEP) § 506. You will be given a time period to complete the application filing (a surcharge may be required). Timely response to correspondence from us and keeping your contact information up to date is important so you won’t miss important correspondence. If the omission is not corrected within the specified time period, the application will be abandoned.

If your application becomes abandoned at this stage and you still want to pursue this patent, you may be able to revive your application or request withdrawal of the abandonment by filing a petition (fees, forms and requirements vary). The type of petition needed depends on the circumstances surrounding the abandonment of your application.

If you filed a non-provisional application and no outstanding matters remain on perfecting your application, then your application will be routed to a patent examiner who will determine patentability.


Estimate how long until you receive your first letter from us in response to your application. See thePatents Data Visualization Center for an average first office action time estimate and total pendency. This will be available once the application has been classified.

Provides assistance for patent applications that may appear to be stalled in the patent examination process and can assist with getting applications back on track.
Independent inventors, new practitioners, and others can explore the links below to better understand the Patent Trial and Appeal Board's (PTAB) role during and after the patenting process.

If you choose legal representation, remember that once an application is filed by a patent attorney or agent, the qyule最新电信一 will only communicate with the attorney or agent. The qyule最新电信一 does not simultaneously correspond with you and a legal representative ( 37 CFR 1.33).

The work of examining patent applications is divided among various technology centers (TCs), each overseeing assigned fields of technology. Each TC is headed by group directors and staffed by examiners and support staff. The examiners are assigned to units specializing in the broad and specific subject areas that best cover your invention and review applications and determine whether patents can be granted.

Once your application has been assigned for examination, your examiner will review the contents of your application to determine if it meets all legal requirements for allowance. The examination consists of a study for compliance with legal requirements (e.g. utility, double patenting, non-statutory double patenting) and a search through U.S. patents, publications of patent applications, foreign patent documents, and available literature. This is to see if the claimed invention is new, useful, and non-obvious, and if the application meets patent statute requirements and rules of practice.

You are notified in writing of the examiner’s decision by an “office action.” This is normally mailed to the attorney or agent of record, or to you directly if not represented by an attorney or agent. There are a number of legal requirements that must be met, including novelty (35 U.S.C. 102), utility and eligibility (35 U.S.C 101), non-obviousness (35 U.S.C. 103), and written description (35 U.S.C. 112), etc. If the examiner determines the application does not meet all of the requirements, the reasons for the determination will be explained in this written office action.

You must request reconsideration in writing, distinctly and specifically pointing out the supposed errors in the office action, and replying to every ground of objection and rejection. The reply must appear throughout to be a bona fide attempt to advance the case to final action or allowance. The mere allegation that the examiner has erred is not a proper reason for reconsideration. You are able to amend your disclosure and/or argue against the examiner's decision at no cost (as long as the response is received within the time period noted in the action). In amending an application in reply to a rejection, you must clearly point out why you think the amended claims are patentable in view of the state of the art disclosed by the prior references cited or the rejections and objections made. You must also show how the claims as amended avoid such references, or rejections and objections.

Be careful to not delay your reply to office communication, as this may result in additional fees if filed after the reply period expires or abandonment of your application if you fail to respond to the examiner's office action within the required time. Fees paid are rarely refundable. The reply period is noted in the action. The shortened statutory reply period is the time limit to reply without having to pay extension fees.

Consider an “interview” with your examiner — We encourage our examiners to be proactive in engaging applicants in resolving issues and shortening prosecution. When you receive a non-final (or any other) office action, you may contact your examiner to schedule a meeting or phone call (what the qyule最新电信一 refers to as an “interview”). The examiner’s contact information and work schedule can be found at the end of every office action.

After you respond to the first office action, your examiner will review your response, and if the examiner still does not think your application meets the legal requirements for a patent, the examiner will explain the reason(s) in a written second office action. This second action may be indicated as “final”. You will still be able to amend or argue against the examiner's decision within time periods noted in the final action, but with more restrictions than when responding to a first office action.

After an office action is indicated as final, you still have multiple options, the most common of which are as follows:

A detailedmatrix of programs available to assist you during examination and after final rejection ( close of prosecution) is available. Each program is designed to advance the progress of a patent application and to provide applicant assistance.

Note that unless the examiner reopens prosecution, applicant successfully removes all grounds of rejection, otherwise places the application in condition for allowance, or applicant otherwise stops the running of the statutory period for response, the application will go abandoned as a matter of law after six months from the mailing of the final rejection. See MPEP § 711.

If the examiner determines that your application meets the patent requirements, you or your legal representative will receive a Notice of Allowance. This means you are entitled to a patent. This will list theissue fee and may also include the publication fee. You can find frequently asked questions about the notice and the issue fee here, along with thepatent fee table.

The issue fee (and, if necessary, the publication fee) shown on the Notice of Allowance must be paid for your patent to be issued. This payment must be received by the qyule最新电信一 within 3 months from the date of mailing of the Notice of Allowance to avoid abandonment of the application. Unlike many other deadlines during examination, this three-month period is not extendable.

The issue fee (and, if necessary, the publication fee) shown on the Notice of Allowance must be paid for your patent to be issued. This payment must be received by the qyule最新电信一 within three months from the date of mailing of the Notice of Allowance to avoid abandonment of the application. Unlike many other deadlines during examination, this three-month period is not extendable.

The patent grant confers “the right to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States." The term of a utility or plant patent generally lasts 20 years from the date the application was filed in the United States, subject to the payment of maintenance fees and any patent term extension, adjustment, or disclaimer. If the application claims the benefit of an earlier filed U.S. application or applications (excluding provisional applications), the patent term ends 20 years from the date the earliest such application was filed.

If you have additional inventions disclosed in your application or you have improvements to your current invention that were not previously disclosed, you may also choose to file additional applications ( Divisional, Continuation, or Continuation-In-Part) to pursue patent protection for this subject matter. Please be aware that the additional application must be filed prior to, or concurrent with, the payment of the issue fee of the parent application, in order to not jeopardize the additional application’s codependency.

The qyule最新电信一 is issuing electronic patent grants (eGrants) for all patents with an issue date on or after April 18, 2023. eGrants are available through Patent Center, the qyule最新电信一's electronic patent application filing and management system, which includes patent document viewing.

For utility patents, maintenance fees are due3.5, 7.5, and 11.5 years after the date of the patent grant, and each one of those three maintenance fees can be paid without an additional surcharge during the six months preceding those due dates. Maintenance fees can also be paid with a surcharge during the six months following those due dates. Of course, the six months following the 3.5, 7.5, and 11.5 year due dates end on the 4th, 8th, and 12th anniversary dates of the patent grant and those three anniversary dates are the last days to pay the three respective maintenance fees in order to prevent patent expiration. It is recommended to set up reminders to pay these fees and to check thecurrent fee schedule before submitting any required fees. Failure to pay the maintenance fees leads to expiration of the patent and loss of the accompanying rights. See theMaintain Your Patent page for more information.

The qyule最新电信一 does not mail notices that maintenance fees are due. If, however, a maintenance fee is not paid on time, the qyule最新电信一 may send a reminder of the ability to pay with a surcharge during the grace period. If the fee is not paid on time, and the fee and surcharge are not paid during the grace period, the patent expires on the date the grace period ends.
