How to Patent a Product: Requirements, Fees, and Timeline

To patent a product in the United States, you file an application with the U.S. Patent and Trademark Office showing that your invention is useful, new, and not an obvious variation on something that already exists. For a utility patent — the type most product inventors need — government filing fees run about $2,000 for a large entity, $800 for a small entity, and $400 for a micro entity, and the examination process typically takes close to three years from filing to a final decision. Attorney fees for preparing the application usually cost several times more than the government fees, and the quality of that drafting has a bigger effect on the patent’s value than almost anything else you do.

The Three Legal Requirements Your Product Has to Meet

Federal law puts three hurdles in front of every patent application. Miss any one and the application fails.

Utility means the product does something practical. Under 35 U.S.C. § 101, a patent can cover a new and useful machine, manufactured item, or composition of matter.¹ The bar is low, but abstract ideas, laws of nature, and naturally occurring substances are out.

Novelty means the invention is genuinely new. Under 35 U.S.C. § 102, if the product was already patented, described in a publication, publicly used, or on sale before your effective filing date, it counts as prior art and you cannot patent it.² There is a one-year grace period for disclosures traced back to the inventor: if you publicly demonstrate or sell your own product, you still have twelve months to file.³ The grace period does not cover a third party who independently publishes the same idea before you file.

Non-obviousness blocks patents on trivial tweaks. Under 35 U.S.C. § 103, the examiner asks whether someone with ordinary skill in the relevant technical field would have found the differences between your product and existing products obvious before your filing date.⁴ Combining two known components in a predictable way rarely clears this bar, and this is where most rejections happen.

Choose the Type of Patent That Fits Your Product

Before you draft anything, decide which type of patent matches what makes your product valuable.

A utility patent protects how a product works — its function, mechanism, or chemical composition. It lasts twenty years from the filing date and is the standard choice for mechanical devices, manufactured goods, and new materials.⁵
A design patent protects the ornamental appearance of a product — its shape, surface pattern, or visual configuration — but not how it works. It lasts fifteen years from grant. Consumer electronics companies often file both a utility patent for the internal technology and a design patent for the external look.⁶
A plant patent covers a new and distinct plant variety that has been asexually reproduced. Tuber-propagated plants and plants found in the wild are excluded.⁷

Most product inventors need a utility patent, and the rest of this guide focuses there. If your product’s value is its look rather than its operation, a design patent has a shorter, simpler application format with its own rules.

Provisional Application First, or Straight to a Full Filing

A provisional patent application is an inexpensive way to lock in a filing date before you commit to a full application. The government fee is $325 for a large entity, $130 for a small entity, or $65 for a micro entity.⁸ The USPTO does not examine it and does not require formal claims. It holds the description you submit and stamps a priority date on it.

That priority date is the point. If you file a provisional in January and a competitor independently files for the same invention in June, your January date wins. You then have twelve months to file a nonprovisional application claiming the benefit of the provisional’s date.⁹ Miss that twelve-month window and the provisional expires and the priority date is gone.

The catch: your provisional must describe the invention thoroughly enough for someone skilled in the field to build and use it. A vague sketch filed just to grab a date will not hold up during examination or in court. Treat the provisional like a less formal version of the full specification, not a placeholder.

What Goes Into a Nonprovisional Utility Application

The nonprovisional application is the real filing. It has several required parts, each doing a specific legal job.

Specification and Claims

The specification is the written description of your invention. Federal law requires it to explain the product clearly enough that a person skilled in the relevant technical field could build and use it without guessing.¹⁰ It includes a title, a brief summary, and a detailed description of the components, how they fit together, and how the product operates. Cover the preferred version and any important variations.

The claims section is the most legally significant part of the entire application. Claims define the boundaries of your patent rights and are what a court reads when deciding whether someone infringed. Each claim is a single sentence, often long and carefully structured, that identifies the specific combination of features you own. Broad claims cover more ground but are harder to defend against prior art. Narrow claims survive examination more easily but give competitors room to design around your patent. Balancing that is where patent attorneys earn their fees and the biggest reason most inventors hire professional help.

Technical Drawings

Drawings are required whenever they are necessary to understand the invention’s physical structure, and nearly every product patent includes them. The USPTO enforces strict formatting rules on line thickness, shading, numbering, and margins. Each numbered part in the drawings has to correspond to a specific term in the written description. Professional patent draftspersons typically charge $100 to $500 per sheet depending on complexity.

Information Disclosure Statement

Everyone involved in preparing and filing the application has a legal duty to disclose information that could affect whether the patent should be granted.¹¹ The Information Disclosure Statement is how you do it: list every patent, publication, and prior product you know about that relates to your invention, and provide copies of foreign patents and non-patent publications. Hiding prior art that later surfaces can render the entire patent unenforceable.

Administrative Forms

The Application Data Sheet gives your legal name, residence, contact information, and the invention title. The inventor’s declaration is a sworn statement that you are the original inventor and have complied with your duty to disclose relevant information.¹² Both are available on the USPTO website, though the office does not require its specific forms as long as your submission includes all legally required information.

Filing Fees and Entity Size

The USPTO charges different rates depending on the size of the applicant, so classify yourself correctly before you file.

Large entity is the default. Anyone who does not qualify as small or micro pays full price.
Small entity covers individuals who have not assigned their patent rights to a large company, businesses with fewer than 500 employees, and nonprofit organizations. Small entities pay roughly 60% less than large entities on most fees.
Micro entity is a small entity that also meets two more tests: gross income in the prior year did not exceed $251,190, and neither the applicant nor the inventor has been named on more than four previous U.S. patent applications. Micro entities pay roughly 80% less than large entities.¹³

For a utility patent filed electronically, the combined basic filing fee, search fee, and examination fee totals $2,000 for a large entity, $800 for a small entity, or $400 for a micro entity.⁸ Filing on paper instead of electronically adds a $400 non-electronic filing surcharge ($200 for small and micro entities). These are only the initial government fees. You will also owe an issue fee if the patent is granted and maintenance fees afterward.

Attorney fees dwarf the government costs. Expect roughly $5,000 to $15,000 for a patent attorney or agent to prepare a standard-complexity utility application, with more complex inventions running higher. A professional prior art search before filing typically costs $300 to $3,500. A poorly drafted application with weak claims may get filed for the price of the government fees, but it rarely results in a patent worth owning.

What Happens After You File

All nonprovisional utility applications are filed through the USPTO’s Patent Center, which fully replaced the older EFS-Web portal in November 2023.¹⁴ Once filed, you get a confirmation with a unique application number and your official filing date. From that point you can mark your product “patent pending,” but the label carries no enforceable rights against infringers until the patent actually issues.

Your application is assigned to an examiner with expertise in the relevant technical field. As of early 2026, the average time from filing to a first office action is about 22 months, and the average total time from filing to a final decision is roughly 33 months.¹⁵ Your application is typically published 18 months after the earliest filing date, making the details public.¹⁶ You can request non-publication if you will never file the application in a foreign country, but most applicants do not.

The examiner searches existing patents and published literature and compares your claims against everything found. Most applicants receive an office action: a formal letter listing reasons for rejecting some or all claims, or requesting clarifications. This is normal, not a sign the application is doomed. The shortened deadline for responding is typically two or three months, and you can buy extensions up to a six-month statutory maximum by paying additional fees.¹⁷ Miss the six-month outer deadline and the application is treated as abandoned.¹⁸

If the examiner accepts your responses, you receive a Notice of Allowance. You pay the issue fee — $1,290 for a large entity, $516 for a small entity, or $258 for a micro entity — and the patent grants.⁸

If your amended claims still do not satisfy the examiner, you receive a final rejection. “Final” is somewhat misleading. It does not end the process, but it does limit your options: file a request for continued examination for an additional fee, amend the claims within the narrow window allowed after final rejection, or appeal to the Patent Trial and Appeal Board.¹⁹

Track One if You Cannot Wait Three Years

If waiting nearly three years is not workable, the USPTO offers a Track One prioritized examination program for utility patents. Track One applications receive a final decision within about twelve months of the filing date and the program does not require a pre-examination prior art search.²⁰

The cost is steep: $4,515 on top of the regular filing fees for a large entity, $1,806 for a small entity, or $903 for a micro entity.⁸ The USPTO caps acceptance at 20,000 prioritized requests per fiscal year, so the program can fill up. For products in fast-moving markets, a two-year head start on competitors often justifies the extra expense.

After the Patent Issues: Marking and Maintenance

Once your patent issues, mark the product with the patent number. Marking is not required for the patent to be valid, but skipping it has a real financial consequence: without proper marking, you generally cannot recover damages from an infringer unless you can prove they had actual notice of the patent.²¹ The simplest approach is to print “Pat.” followed by the patent number on the product. If the product is too small, virtual marking works: print a URL on the product or packaging that links to a free, publicly accessible webpage listing the patent number associated with that product. Falsely marking a product as patented when it is not can result in a fine of up to $500 per offense.²²

A utility patent does not simply last twenty years on autopilot. You have to pay maintenance fees at three intervals after issuance or the patent expires. As of 2026:⁸

3.5 years after issuance: $2,150 large entity, $860 small, $430 micro
7.5 years after issuance: $4,040 large, $1,616 small, $808 micro
11.5 years after issuance: $8,280 large, $3,312 small, $1,656 micro

Miss a payment and there is a six-month grace period during which you can still pay with a $540 surcharge ($216 small, $108 micro). After that, the patent expires. Calendar the due dates the day your patent issues; this is one of the most avoidable ways to lose patent protection. Design patents, by contrast, require no maintenance fees, and their fifteen-year term runs from the grant date with no additional payments.
