How much does a patent cost in total?

For a typical utility patent, total cost from filing to issue generally runs $12,000 to $25,000, spread over two to four years. That covers attorney fees to prepare and file, USPTO fees based on entity size, and one to three office action responses during examination. A provisional application alone costs substantially less.

What is the difference between the Standard and Litigation-Ready tiers?

Standard Filing covers everything needed to prepare, file, and prosecute a solid application: disclosure interview, prior art search, full specification and claim set, formal drawings, filing, and docketing. Litigation-Ready adds analysis aimed at surviving a challenge: claim-strength review against known invalidity theories, tiered fallback claims, a competitor patent landscape review, freedom-to-operate flags on your actual product, a claim construction memo, and an estoppel budget governing prosecution amendments.

Why do patent costs vary so much?

The two biggest drivers are technical complexity and how difficult examination turns out to be. A simple mechanical device takes far less drafting time than a multi-component software system. An application allowed after one office action costs thousands less than one requiring three rounds plus an appeal.

What are USPTO entity sizes and how do they affect fees?

The USPTO discounts its fees by applicant size. Micro entity status offers the largest discount and requires meeting income and prior-filing limits. Small entity status applies to businesses under 500 employees, universities, and nonprofits. Large entities pay full fees. Claiming a discount you do not qualify for can render a patent unenforceable, so entity status should be verified carefully.

Are there ongoing costs after a patent issues?

Yes. U.S. utility patents require maintenance fees at 3.5, 7.5, and 11.5 years after issue, and the amounts increase at each stage. Missing one causes the patent to expire permanently. Design patents require no maintenance fees.

Our fees

Two tiers, both flat-fee

We quote a fixed fee in writing and you approve it before any work begins. If scope changes, we re-quote rather than surprise you. Hourly billing on drafting creates an incentive we'd rather not have.

Standard Filing

$7,000–$11,000Attorney fees · USPTO fees separate

Invention disclosure interview with the attorney who drafts it
Prior art search and written patentability opinion
Complete specification and claim set
Formal drawings to USPTO standards
Inventor declaration, IDS, entity-status filings
Electronic filing and filing-receipt review
Full deadline docketing for the life of the matter

Right for: a first patent in an uncrowded field, or a primarily defensive filing where you don't expect to enforce.

Litigation-Ready

$14,000–$24,000Attorney fees · USPTO fees separate

Everything in Standard Filing, plus:
Claim-strength review — your claim set run against the standard invalidity theories under §§ 101, 102, 103, and 112
Tiered fallback claims — independently meaningful positions so one bad reference doesn't take the whole set
Competitor patent landscape mapped before drafting starts, so we know what we're drafting around
Freedom-to-operate flags on your actual product, while design changes are still cheap
Claim construction memo — how we expect each key term to be read, and why
Estoppel budget — every narrowing amendment priced against surrendered equivalents before we file it
Continuation strategy — a plan for keeping the family alive past first allowance

Right for: founders facing due diligence, companies in crowded fields, and anyone who expects to enforce.

Start your application

Which one do you need?

We'll tell you honestly, and it's often Standard. The premium tier only earns its cost when your patent is genuinely likely to be tested — we wrote out when you don't need it rather than leaving you to guess.

Everything else

Other work, same flat-fee approach

Fees for additional patent services
Service	What it covers	Fee
Provisional application	Filing date and patent pending status, drafted with the rigor of a full application because a thin provisional protects nothing.	$2,500–$4,500
Design patent	Formal design drawings in all required views plus the single design claim.	$1,800–$3,000
Patentability search	Prior art search plus written opinion. Credited toward your application if you proceed with us.	$800–$2,000
Freedom-to-operate analysis	Whether your product can ship without infringing live claims. Scope depends on how crowded the field is.	$5,000–$15,000
Portfolio audit	Your existing patents read against real invalidity and enforceability failure modes, with a fixable/not-fixable verdict on each.	$2,500–$6,000
Office action response	Analysis of cited references, claim amendments, and legal argument — with the estoppel cost priced before we amend.	$1,500–$4,000
Examiner interview	Preparation and conduct of an interview with the examiner, in person or by video.	$600
Provisional → non-provisional conversion	Expanding a provisional into a full application with formal claims and drawings.	$5,000–$10,000
PCT international application	Preparation and filing of the PCT application. National phase entries quoted per country.	$4,000–$7,000
Appeal to the PTAB	Appeal brief and supporting argument when prosecution reaches an impasse.	$5,000–$12,000

Government fees

What the USPTO charges on top

These go to the government, not to us. The amount depends on your entity size — the single easiest lever on the cost of a patent.

Micro entity

The largest discount. Requires meeting gross-income limits and a cap on prior applications filed, or affiliation with an institution of higher education.

Lowest USPTO fee tier.

Small entity

Independent inventors, businesses with fewer than 500 employees, universities, and nonprofits. The most common status among our clients.

Reduced USPTO fee tier.

Large entity

Everyone else — typically companies of 500 or more employees, or applicants who have licensed rights to one.

Full undiscounted fees.

Get entity status right

Claiming a discount you don't qualify for isn't a minor paperwork error — it can render an issued patent unenforceable. Licensing rights to a large company can silently change your status mid-prosecution. We verify status at filing and revisit it whenever your business situation changes.

The USPTO fees you'll encounter

USPTO fees by stage
Fee	When it's due
Provisional application filing fee	At provisional filing
Filing, search, and examination fees	At non-provisional filing
Excess claim fees	At filing, if over 20 total or 3 independent claims
Track One prioritized examination (optional)	At filing, to compress examination to roughly a year
Extension of time fees	Only if a response deadline needs extending
Request for Continued Examination (RCE)	If prosecution continues past a final rejection
Issue fee	After a Notice of Allowance
Maintenance fees	3.5, 7.5, and 11.5 years after issue — increasing each time

USPTO fee amounts change periodically. Current official amounts are published at uspto.gov. We confirm the current figures for your entity size in your written quote.

Budgeting

What actually drives the number

Technical complexity

A mechanical device with six parts takes far less drafting time than a distributed software system with a dozen interacting components and multiple claim types. Complexity affects the specification, the drawings, and the claim set at once.

How many embodiments you want covered

Broad, durable protection comes from describing variations — alternative materials, configurations, and methods. Each adds drafting time, and each makes the patent harder to design around. After Amgen, it's also what keeps a broad claim enabled. This is usually money well spent.

How examination goes

The biggest variable, and unpredictable at filing. An application allowed after a single office action costs thousands less than one requiring three rounds, an RCE, and an appeal. Examiners vary, art units vary, luck is real. A good prior art search up front is the best lever you have on this.

Foreign filing

Costs multiply per country — filing fees, translations, local agents, and separate prosecution in each. This is why we push hard on which countries genuinely matter to your business. For most clients the honest answer is one or two, not ten.

A realistic total

For a typical utility patent taken from filing through issue, plan on $12,000–$25,000 all-in, spread across two to four years rather than paid at once. Most clients pay in stages as each phase begins, which makes it considerably easier to absorb than the total suggests.
