Patent Filing Costs: What to Budget in 2026
The sticker price of a patent application is only the beginning. Attorney fees, government fees and maintenance costs stack up over the life of a patent, and underestimating them is the most common budgeting mistake.
A complete picture matters because a patent lasts up to 20 years, and you will keep paying small fees the whole way to keep it alive.
Where the money goes
- Attorney drafting: often the single largest line item
- Government filing, search and examination fees
- Drawings and formal illustrations
- Office action responses as the examiner pushes back
- Maintenance fees due at years 3.5, 7.5 and 11.5
Ways to keep costs down
- File a provisional first to lock a date cheaply
- Do your own prior art search before hiring help
- Compare flat-fee packages from boutique firms
- Qualify for small or micro entity discounts
Budget for the full life of the patent, not just the filing day, and you will never be caught off guard by a renewal invoice.
The hidden costs
Renewal fees are easy to forget but add up fast, and abandoning a patent at the wrong moment wastes everything you already spent.
- Maintenance fees rise at each milestone
- Foreign filings multiply the total
- Track every due date from day one
