What Is a "Pro Se" Patent Application?
The USPTO allows any inventor to file their own patent application without legal representation. This is called filing "pro se" — Latin for "on one's own behalf." There are no rules preventing it. The USPTO even provides basic filing guides and forms.
So yes — you can file a patent yourself. The real question is whether you should.
What the Data Says About Pro Se Patents
Multiple studies of USPTO examination outcomes show a consistent pattern: patent applications filed without an attorney have significantly lower grant rates than those filed with professional representation. But grant rate is only part of the picture.
The more consequential difference is in claim scope. Even when a pro se application is granted, the resulting patent often contains narrow claims that are easy for competitors to design around. A patent with narrow claims can be nearly worthless in a real enforcement situation.
This happens because writing patent claims — the numbered sentences at the end of a patent that legally define the scope of protection — is a highly technical skill. It requires both legal expertise and a deep understanding of the prior art landscape.
What a Registered USPTO Patent Attorney Actually Does
A registered USPTO patent attorney (or agent) has passed the USPTO's technical examination and is authorized to prosecute patent applications before the USPTO. Here is what that representation actually involves:
- Prior art search and patentability analysis: Before you spend money on a full application, an attorney can assess whether your invention is likely to be patentable in light of existing patents and publications.
- Claims drafting: This is the most critical and most misunderstood part. Well-drafted claims are broad enough to cover variations of your invention, specific enough to be granted, and strategically structured to be difficult to design around.
- Application preparation: The specification, drawings requirements, abstract, and formal statements must meet strict USPTO rules. Errors can create legal vulnerabilities that last the life of the patent.
- Office action responses: When the USPTO rejects (most applications are rejected at least once), an attorney responds to the examiner's arguments and negotiates the scope of allowable claims.
- Strategic prosecution: An experienced attorney knows which battles to fight with an examiner, when to amend, and how to build a prosecution history that supports future enforcement.
When Pro Se Filing Might Make Sense
There are limited situations where filing without an attorney might be reasonable:
- Provisional patent applications for early-stage inventors who primarily need "patent pending" status and 12 months of time to evaluate commercial potential before committing to a full application. Even here, professional help improves the document.
- Very simple, single-claim inventions in a technology area with a sparse prior art landscape — rare in practice.
- Inventors with technical patent drafting experience who understand claim construction and USPTO practice.
In nearly every other case, the cost of professional representation is justified by the improved quality and scope of protection.
The Real Cost Comparison
Many inventors think they are saving money by filing pro se. Consider the true cost comparison:
- A pro se utility patent application might cost $1,000–$3,000 in USPTO fees alone.
- A professionally filed utility patent application typically costs $8,000–$15,000 total (fees + attorney), depending on technology complexity.
- A patent that is too narrow to enforce, or that a competitor can work around with minor changes, has near-zero commercial value — regardless of what you paid to obtain it.
- Correcting a poorly drafted patent after the fact is often impossible without starting over.
When you factor in the potential value of the IP being protected — and the cost of rebuilding a position if the first application fails — professional representation is typically the better investment.

Frequently Asked Questions
Can I convert a pro se application to attorney representation later?
Yes. You can hire a patent attorney at any point during prosecution. However, certain strategic options — such as certain claim amendments and prosecution history arguments — become limited or unavailable as prosecution advances. Earlier representation generally produces better outcomes.
What is the difference between a patent attorney and a patent agent?
Both are registered with the USPTO and authorized to prosecute patent applications. A patent attorney is also a licensed attorney and can provide broader legal advice — including contracts, licensing, litigation, and IP strategy. A patent agent is authorized for USPTO prosecution only.
Does a patent attorney need to be located in North Dakota?
No. USPTO patent prosecution is a federal practice — your patent attorney can be located anywhere in the United States. That said, many inventors prefer working with a local attorney for easier communication and someone who understands the regional business context. Fargo Patent Law serves clients throughout North Dakota, Minnesota, and nationwide.
