Steps to Apply for a Patent

Applying for a patent in the United States involves a multi-step legal process managed by the United States Patent and Trademark Office (USPTO). Because patent applications are complex legal documents, the Patent Office recommends consulting a licensed patent attorney or agent. This article is written by a licensed patent attorney who has practiced in patent law for over 10 years.

1. Confirm Eligibility and Type

Eligibility: Your invention must be novel (new), useful, and non-obvious to someone skilled in the field.
Determine which category fits your invention:
Utility: For new processes, machines, or compositions of matter (most common).
Design: For new, original, and ornamental designs for an article of manufacture.
Plant: For distinct and new plant varieties.

2. Conduct a Patent Search

An Information Disclosure Statement (IDS) is a formal submission to the U.S. Patent and Trademark Office (USPTO) that lists prior art or other information known to the applicant that may be relevant to patentability. Filing an IDS fulfills the applicant’s duty of candor and good faith to the USPTO under 37 C.F.R. § 1.56. In short: if you know about prior art that could matter, you must disclose it. That’s why you need to conduct a Prior Art Search before filing a patent.

Free patent search databases like Google Patents, USPTO Patent Public Search, and Espacenet provide basic searching functionality with access to millions of patents at no cost. These platforms serve well for initial exploration, basic prior art searching, and educational purposes. However, free patent search tools are often difficult to use because they are designed for technical precision rather than user-friendliness, and they frequently suffer from data gaps, unintuitive interfaces, and a lack of advanced filtering.

So should you find a Paid Search Service? If you are planning to bring a product to market or seeking significant investment, a missed patent could lead to a $3 million+ infringement lawsuit. If your invention is in a highly technical field like biotech or software, professional researchers use specialized databases for chemical structures or biological sequences that free tools cannot handle. Professional searches provide expert interpretation, helping you draft stronger legal claims that are less likely to be rejected by the Patent Office.

3. Choose Between Provisional and Non-provisional for Utility Patent

If you need to protect how your invention looks, go filing a Design application, else you need to protect how your invention works, Utility Patent will be your choice, keep reading.

Provisional (Utility) Patent is often used as a lower-cost placeholder. It establishes an early filing date and gives you 12 months to refine the invention while using the term “patent pending”.

While the Non-provisional Utility Patent is the formal application that is actually examined by the USPTO and can eventually lead to a granted patent.

This distinction is critical: the provisional application secures priority but lacks legal enforceability, whereas the non-provisional initiates substantive examination—requiring Claims, formal Drawings, and full Specification. Filing both strategically maximizes protection while allowing time for market testing and iterative development.

4. Prepare the Utility Patent Application

A complete Non-provisional Utility application must include:
1) Specification: A written description of the invention and how to make and use it.
2) Claims: Numbered sentences that define the legal boundaries of your invention’s protection.
3) Drawings: Required if they are necessary to understand the invention.
4) Oath or Declaration: A formal statement by the inventor(s).
5) Application Data Sheet (ADS): Containing basic administrative information.
6) Information Disclosure Statement (IDS): listing prior art or other information known to the applicant that may be relevant to patentability.
7) POA: Power of Attorney signed by the applicant.

5. File and Pay Fees

You must pay filing, search, and examination fees. Fees vary by entity size; individuals often qualify as “Micro Entities“, receiving up to an 80% discount. Small businesses with less than 500 employees and universities often qualify as “Small Entities“, receiving up to an 60% discount.

6. Request Expedited Examination (Optional)

After filing, the USPTO generally takes 18-26 months to issue the first Office Action for non-expedited utility applications. Plus the time of prosecution period and 2-4 months after the Notice of Allowance and payment of the issue fee, it normally takes around 3 years to get an utility patent granted.

If 3 years is too long for your business goals, there are several “fast-track” options available to move your application to the front of the line.

Choosing the right approach for your situation to expedite the examination requires professional expertise, we encourage you to consult a patent attorney for help.
