How Much Does It Actually Cost to Patent an Invention?
One of the most common questions we hear from inventors is: "How much will patenting my invention cost?" The answer isn't simple, because patent costs vary dramatically based on your choices: filing strategy, whether you use an attorney, which type of patent you pursue, and how many countries you target.
This guide breaks down every cost category you'll encounter, from initial USPTO filing fees to international protection and ongoing maintenance. By the end, you'll know exactly what to budget for your patent journey.
USPTO Filing Fees (2026)
The U.S. Patent and Trademark Office sets official filing fees. These vary based on entity type and patent type.
Micro-Entity Rates (Lowest Cost)
If you qualify as a "micro-entity," you get an 80% reduction on most USPTO fees. Most independent inventors qualify. To be a micro-entity, you must:
- Qualify as a small entity (independent inventor, small business with fewer than 500 employees, nonprofit, or university)
- Have gross income in the prior year less than 3× the median U.S. household income (approximately $241,830 for 2025)
- Not have been named as inventor on more than 4 prior non-provisional applications (excluding provisional, foreign-only, or applications filed under prior employment)
- Not have assigned (or be obligated to assign) the application to an entity that itself fails the income test
- File a certification of micro entity status (Form PTO/SB/15A or PTO/SB/15B) at filing — without it, you'll be charged at large-entity rates
Below are the actual USPTO fees as of the January 19, 2025 fee schedule (last revised April 1, 2026):
| Fee | Micro-Entity | Small Entity | Large Entity |
|---|---|---|---|
| Provisional Application Filing Fee | $65 | $130 | $325 |
| Non-Provisional Utility — Basic Filing Fee | $70 | $140 | $350 |
| Non-Provisional Utility — Search Fee | $154 | $308 | $770 |
| Non-Provisional Utility — Examination Fee | $176 | $352 | $880 |
| Non-Provisional Utility — All three combined | $400 | $800 | $2,000 |
Small Entity Rates
If you don't qualify for micro-entity status but are an independent inventor, small business with fewer than 500 employees, nonprofit, or university, you qualify for small entity status and a 60% reduction on most USPTO fees. You must file a certification of small entity status (or check the small-entity box in Patent Center) at filing.
How to File: The Two-Path Strategy
Most inventors use a two-step strategy that balances cost and protection.
Path 1: Provisional + Non-Provisional (Recommended)
Year 1: Provisional Patent
- Filing fee (micro-entity): $65 (small entity $130; large entity $325)
- DIY preparation cost: $0 to $500 (materials, software)
- Professional help (optional): $500 to $1,500
Year 1-2: Non-Provisional Patent
- USPTO filing + search + examination fees (micro-entity): $400 combined (small entity $800; large entity $2,000)
- Attorney preparation (optional): $1,500 to $5,000
Total for U.S. protection via provisional + non-provisional: $465 in USPTO fees alone at micro-entity rates ($930 small / $2,325 large), or up to ~$7,000 with attorney support.
Path 2: Direct Non-Provisional Filing
Skip the provisional application and file directly to the USPTO. This saves the provisional fee but requires more work upfront.
- USPTO filing + search + examination fees (micro-entity): $400 (small entity $800; large entity $2,000)
- Attorney preparation: $2,000 to $6,000
Total for direct non-provisional: $400 (micro-entity DIY) to $8,000 (large entity with attorney).
Most inventors prefer the provisional route because it provides a 12-month grace period to refine the invention and prepare a stronger non-provisional application.
Attorney and Professional Fees
Patent attorneys and agents charge significantly for their expertise. Here's what to expect:
Patent Attorney Fees (Hourly or Flat-Fee)
- Hourly rates: $150 to $400+ per hour (varies by location and experience)
- Provisional application prep: $800 to $2,500
- Non-provisional application prep: $2,000 to $5,000+
- Office Action response: $500 to $2,000 per response
- Amendment and prosecution: $300 to $1,500 per revision
Patent Agents (Lower-Cost Alternative)
Patent agents are not lawyers but are certified by the USPTO to draft and prosecute patents. They typically charge 20-30% less than attorneys.
- Provisional application prep: $600 to $1,800
- Non-provisional application prep: $1,200 to $3,500
- Hourly rates: $100 to $250/hour
Maintenance Fees: The Hidden Cost
Once your utility patent issues, the USPTO requires maintenance fees to keep it active. These are due at 3.5, 7.5, and 11.5 years after issuance.
| Maintenance Period | Micro-Entity | Small Entity | Large Entity |
|---|---|---|---|
| 3.5 years | $430 | $860 | $2,150 |
| 7.5 years | $808 | $1,616 | $4,040 |
| 11.5 years | $1,656 | $3,312 | $8,280 |
| Total over 20 years | $2,894 | $5,788 | $14,470 |
If you miss a maintenance fee deadline, there is a 6-month grace period with a surcharge (currently $160 for micro-entity, $320 for small entity, $800 for large entity). After the grace period, the patent expires and the invention enters the public domain.
International Patent Costs
If your invention has global market potential, protecting it internationally is essential. However, costs escalate significantly.
PCT Filing (Patent Cooperation Treaty)
The PCT allows you to file once and extend to 190+ countries. Key costs:
- PCT application fee: $1,600 to $2,000 (micro-entity)
- Search report: $300 to $600
- Preliminary examination (optional): $400 to $800
National Phase Filing
After the PCT, you must file in individual countries. Typical costs per country:
- Europe (EPO): $1,500 to $3,000 per application
- Japan (JPO): $1,200 to $2,500
- China (CNIPA): $800 to $1,500
- Canada: $800 to $1,500
- Australia: $600 to $1,200
Example: Filing in U.S., Europe, Japan, and China:
PCT application: $2,000 + National filings (~$7,000–$10,000) = $9,000–$12,000 in filing fees alone, plus translation costs (~$2,000–$4,000) and attorney representation in each country (additional $5,000–$15,000).
Most independent inventors focus on U.S. protection first, then expand internationally only if market demand justifies the cost. Learn more in Module 5: International Strategy.

| Maintenance fees (3.5, 7.5, 11.5 yrs) | $2,894 | $2,894 | $2,894 |
| Total 20-year cost | ~$3,360 | ~$6,960–$7,460 | ~$10,360–$11,360 |
When Is It Worth Patenting?
The total cost of patenting at micro-entity rates ranges from ~$3,000 (DIY) to $11,000 (with attorney) for U.S. protection alone. Ask yourself:
- Will this invention generate at least $5,000–$10,000 in revenue?
- Do competitors have the ability and motivation to copy it?
- Is there a sustainable market for 10+ years?
- Could patent protection help you secure investment or partnerships?
If the answer is yes to most of these, patenting is likely worth the investment. If you're unsure, use our Patent Filing Decision Flowchart to evaluate your specific situation.
Cost-Saving Strategies
- File provisionally first: Defers the larger non-provisional filing fees ($400 micro / $800 small / $2,000 large) by 12 months and gives you time to refine the application and confirm market demand
- Verify micro-entity status: Cuts USPTO fees by 80% — combined non-provisional fees drop from $2,000 to $400. Don't forget to file the certification of micro entity status; without it, you'll be charged at large-entity rates
- Do initial work yourself: Prepare detailed documentation before hiring an attorney
- Use patent agents instead of attorneys: Often 20-30% cheaper with comparable quality
- Prioritize countries: File in the U.S. and key markets first; expand as revenue grows
- Budget for maintenance fees: Micro-entity total over 20 years is ~$2,894 — set aside roughly $145/year to be ready when each fee comes due
Patenting is an investment, not an expense. With careful planning and strategic decisions, you can protect your invention for a reasonable cost.
