To apply for a patent in the United States, you file an application with the U.S. Patent and Trademark Office (USPTO) after confirming your invention qualifies, preparing a written description with formal claims and drawings, and paying government fees that start around $2,000 for a utility patent filing. From filing to a first response from an examiner, expect roughly 22 months. The details you get right at the start decide whether you end up with meaningful protection or a patent so narrow that competitors can design around it.
Confirm Your Invention Qualifies
Three requirements sit at the heart of patentability. Your invention must be novel, meaning it hasn’t been described in an existing patent, published anywhere, or offered for sale before your filing date.1Office of the Law Revision Counsel. 35 U.S. Code 102 – Conditions for Patentability; Novelty It must be non-obvious, meaning someone with ordinary knowledge in your field wouldn’t easily arrive at it by looking at existing technology.2Office of the Law Revision Counsel. 35 U.S. Code 103 – Conditions for Patentability; Non-obvious Subject Matter And it must be useful, meaning it does something practical.3govinfo. 35 U.S.C. 101 – Inventions Patentable
Non-obviousness trips up more applicants than any other requirement. An invention can be completely new and still be deemed obvious if it merely combines existing ideas in a way that would be predictable to someone in the field. Most rejections land here, and arguing back requires knowledge of patent case law.
Certain subject matter is off-limits regardless of how novel it is: abstract ideas, laws of nature, and natural phenomena including naturally occurring products.4United States Patent and Trademark Office. MPEP 2106 – Patent Subject Matter Eligibility An invention isn’t automatically disqualified for touching one of these areas, though. If it applies an abstract idea or natural law in a way that adds something significantly beyond the exception itself, it can still qualify. You can’t patent the mathematics behind an encryption method, but you may be able to patent a novel software system that implements it.
Protect Your Idea Before You File
One of the fastest ways to destroy your rights is to talk about your invention publicly before filing. Under federal law, a prior publication, sale, or public availability generally forfeits your patent rights, with one exception.1Office of the Law Revision Counsel. 35 U.S. Code 102 – Conditions for Patentability; Novelty The United States allows a one-year grace period: if you publicly disclose your own invention, you still have 12 months to file.
Relying on that grace period is risky. Most countries outside the U.S. require absolute novelty, so any public disclosure before filing kills your rights there. And the 12-month clock starts whether you notice or not. A social media post, a conference talk, or offering your product for sale can all trigger it.
When you need to discuss the invention with manufacturers, investors, or partners before filing, use a non-disclosure agreement. Conversations covered by an NDA generally don’t count as public disclosure. You don’t need an NDA to talk to a patent attorney; attorney-client privilege protects those conversations even if you never hire them.
Pick the Right Type of Patent
The USPTO issues three types of patents, each protecting something different.5U.S. Patent and Trademark Office. Description of Patent Types
- A utility patent covers how an invention works: its function, structure, or composition. This is what most people mean by “patent.” It lasts 20 years from the filing date and requires maintenance fees.
- A design patent protects the ornamental appearance of a functional item, not how it works. It lasts 15 years from issuance and has no maintenance fees.
- A plant patent covers new and distinct plant varieties reproduced asexually through cuttings, grafting, or cloning. Tuber-propagated plants such as potatoes and plants found in the wild don’t qualify.
Most individual inventors are filing utility patents, and the steps below focus on that path. A design patent application is simpler and cheaper, but the protection is narrower.
Provisional or Non-Provisional
Utility patent applicants have two filing options, and the choice matters.
A provisional application is a simpler, cheaper placeholder. It establishes an early filing date, lets you label your invention “patent pending” for 12 months, and doesn’t require formal claims or an oath. The tradeoff: it’s never examined and can never become a patent on its own. You must file a full non-provisional application within 12 months to claim the benefit of the provisional’s filing date. That deadline cannot be extended. Miss it and the priority date is gone.6United States Patent and Trademark Office. Provisional Application for Patent
A non-provisional application is the real thing. It gets examined and, if approved, becomes an issued patent. Filing a non-provisional directly, with no provisional first, is perfectly acceptable. Many applicants do exactly that.
Prepare the Application
The quality of what you file decides what protection you end up with. Preparation happens in stages.
Document the Invention Thoroughly
Before writing a single page of the application, put together a detailed invention disclosure. Describe what the invention does, how it works, every component or step involved, and what distinguishes it from existing solutions. Add sketches or diagrams. This document isn’t filed, but your application draws from it. The more detail you capture, the stronger your eventual claims can be.
Do a Prior Art Search
A prior art search identifies existing patents, published applications, and other public documents describing inventions similar to yours. It tells you whether your invention is actually patentable before you spend thousands on the application, and it helps you position your claims around what’s genuinely new. A professional search typically costs $500 to $2,000, with complex inventions in crowded technology areas running $3,000 to $10,000. You can search the USPTO database yourself for free, but professionals know how to dig deeper and read the results.
Assemble the Non-Provisional Application
The law requires your application to include a written description detailed enough that someone skilled in your field could build and use the invention, along with the best way you know of to carry it out.7Office of the Law Revision Counsel. 35 U.S. Code 112 – Specification The full application also needs:
- Claims. These are numbered statements that define exactly what the patent covers. Claims are the legal boundaries of your protection and are the most technically demanding part to draft.
- Drawings. Required whenever they help explain the invention, which in practice means almost always for mechanical or electrical inventions.
- An abstract. A brief summary used for search purposes.
- Inventor information. Names and addresses of every inventor.
Attorney or Pro Se
You can file on your own, called filing “pro se.” The two biggest pitfalls for self-filers are missing critical deadlines they didn’t know existed and failing to overcome non-obviousness rejections. Arguing against an obviousness rejection requires sophisticated knowledge of patent case law.
Attorney fees for preparing and filing a utility patent application typically run $9,000 to $17,000, with simple mechanical inventions at the low end and software or medical device inventions higher. Complex applications can exceed $17,000. These fees are on top of the USPTO’s charges. Claims written by an experienced attorney tend to give broader protection.
Know the Fees and Your Entity Status
The USPTO charges fees at every stage, and your entity status decides how much you pay.8United States Patent and Trademark Office. Save on Fees with Small and Micro Entity Status
- Large entity is the default rate for anyone who doesn’t qualify for a reduction.
- Small entity status, for individuals, small businesses, and qualifying nonprofits, gives a 60% discount on most patent fees.
- Micro entity status requires small entity status plus two more things: you’ve been named on no more than four previous patent applications, and your gross income last year didn’t exceed the annual threshold. Micro entities get an 80% discount.
For a non-provisional utility patent, the combined filing, search, and examination fees at the large entity rate total $2,000 ($350 filing plus $770 search plus $880 examination). A micro entity pays $400 for the same filing. A provisional application costs $325 for a large entity, $130 small, or $65 micro.9United States Patent and Trademark Office. USPTO Fee Schedule
One fee catches people off guard: the USPTO charges a $430 surcharge (large entity) if you file in any format other than DOCX. Small entities pay $172, and micro entities pay $86. Filing in DOCX avoids the charge entirely.
Submit Through Patent Center
Applications go to the USPTO primarily through its online Patent Center system, which handles document uploads and fee payments. You can file by mail, but electronic filing is faster, cheaper, and gives immediate confirmation.10United States Patent and Trademark Office. Applying for Patents
After submission, you’ll receive a filing receipt with a confirmation number and your official filing date. That date matters. It’s the date used to judge novelty against prior art, and the 20-year patent term runs from it.
What Happens After You File
Filing is the beginning. What follows is a back-and-forth with a USPTO examiner that can stretch across months or years.
Waiting for the First Office Action
Your application is assigned to an examiner who specializes in your technology area. As of early 2026, the average wait for the first Office Action is about 22 months.11United States Patent and Trademark Office. Patents Pendency Data Some technology centers average under 19 months, others approach 27.12United States Patent and Trademark Office. First Action Pendency by Technology Center
Responding to Office Actions
Most first Office Actions contain rejections. That’s normal. The examiner explains why specific claims were rejected, usually for obviousness or lack of novelty, and identifies the prior art relied on. You can then amend claims, argue against the rejections, or both.
The USPTO typically sets a shortened response period of three months. You can purchase extensions in one-month increments up to a total of six months from the Office Action’s mailing date, which is the statutory maximum.13United States Patent and Trademark Office. MPEP 710 – Period for Reply Each month of extension has a fee. Miss the deadline entirely and your application is abandoned.
Allowance and Issuance
Once the examiner is satisfied that your claims are patentable, you receive a Notice of Allowance.14United States Patent and Trademark Office. MPEP 1303 – Notice of Allowance You then have three months, not extendable, to pay the issue fee, which is approximately $1,200 for a large entity utility patent. After payment, the patent is granted and published.
Track One if You Can’t Wait Two Years
If waiting close to two years isn’t viable, the USPTO’s Track One prioritized examination program aims to reach a final decision within 12 months of filing. The added cost is real: $4,665 for a large entity ($4,515 request fee plus $150 processing), $1,866 for a small entity, or $933 for a micro entity.9United States Patent and Trademark Office. USPTO Fee Schedule First Office Actions under Track One typically arrive within one to three months. “Final disposition” means an allowance, a final rejection, or an abandonment inside the 12-month target, not a guaranteed patent.
Confirm You’re Entitled to File
Before filing, make sure the invention is yours to file on. The default rule is that the inventor owns the patent rights. Employment agreements often change that.
If you were hired to invent or solve a technical problem, your employer likely owns whatever you create in that role. The same applies if you signed an invention assignment agreement when you started; most tech and engineering companies require them. Corporate officers have a fiduciary duty to assign work-related inventions to the company regardless of any written agreement.
Even for something invented on your own time with your own equipment, your employer may hold “shop rights,” a non-exclusive royalty-free right to use the invention, if the company paid your salary while you developed relevant skills or provided any workspace or materials. If you work in a technical field, read your employment agreement carefully before filing in your own name. When patent rights need to transfer, that’s called an assignment, and it should be recorded with the USPTO’s Assignment Recordation Branch through the online Assignment Center using a Recordation Cover Sheet and the assignment document.15United States Patent and Trademark Office. Patents Assignments: Change and Search Ownership
Plan for What Comes After Issuance
Getting the patent issued isn’t the last expense. Utility patents require maintenance fees at 3.5, 7.5, and 11.5 years after issuance to stay in force, totaling $14,470 over the life of a large entity patent.16United States Patent and Trademark Office. Maintain Your Patent Small and micro entities pay proportionally less. Each due date has a six-month grace period with a surcharge; miss that too and the patent lapses. Design patents and plant patents have no maintenance fees. The 20-year utility term runs from the filing date, so time spent in examination eats into your period of protection.
A U.S. patent only covers the United States. If your invention needs protection abroad, you’ll need to file elsewhere too, and you first need a foreign filing license from the USPTO for any invention made in the U.S. When you file a U.S. application, the license is usually granted automatically and appears on your filing receipt. Filing abroad without it can result in the U.S. patent being declared abandoned.17United States Patent and Trademark Office. MPEP 140 – Foreign Filing Licenses The most practical path to multi-country protection is a Patent Cooperation Treaty (PCT) application, which reserves your right to seek patents in over 150 countries and buys you time (generally 30 months from your earliest filing date) to decide which national filings to pursue.18WIPO. PCT – The International Patent System There’s no such thing as an international patent; each country still issues its own.
