Answers · Patent Costs & Budgeting
How much should a startup budget for patents at each funding stage?
Updated June 2026
The short answer
Published stage-by-stage guides commonly suggest a patent budget in the low five figures through pre-seed and seed (enough for one or two priority filings), roughly $50,000 to $150,000 across Series A as the family and first international filings build out, and six figures per year from Series B onward for broad foreign coverage. The single US filing underneath those numbers is commonly cited at $15,000 to $30,000 or more through grant.
The pattern that matters more than any range: patent costs arrive in waves tied to decisions made years earlier, so the stage where you commit to international protection is two stages before the one where you pay for it. And if your strategy includes a 'game over' IP play, where blanketing a field with filings is the moat, you will need far more patents than these stage ranges suggest and should budget accordingly.
Startup patent budgets by stage (hedged planning ranges, not quotes)
| Funding stage | What the patent budget typically covers |
|---|---|
| Pre-seed | One or two provisional applications to lock priority dates on the core invention. Commonly low four figures to low five figures with professional drafting. |
| Seed | Convert the best provisional to a US utility filing; optionally file a PCT to keep international options open. Published guides commonly suggest $20,000 to $60,000 across the stage. |
| Series A | Second and third families, continuations tracking the roadmap, first office action responses. Commonly $50,000 to $150,000 across the stage. |
| Series B and beyond | PCT national phase entries (the 30-month cliff), foreign prosecution, first maintenance fees. Commonly six figures per year for broad international coverage. |
What each stage is actually buying
Pre-seed money buys priority dates. One or two well-drafted provisionals on the core invention preserve your position for 12 months at modest cost while the product finds its shape. Seed money converts: the strongest provisional becomes a US utility application, and a PCT international application can hold options open in more than 150 countries for roughly 18 additional months without committing to any of them.
Series A money builds the family: continuations that track the product roadmap, filings on the second and third inventions, and the first office action responses on the early applications. Series B money pays the bill the seed-stage PCT created: national phase entries, foreign prosecution, and eventually the first US maintenance fees.
The 30-month cliff
The largest single budget event in a young portfolio is PCT national phase entry, due roughly 30 months from the earliest priority date. Each country carries its own government fees, local counsel, and often translation costs; published estimates commonly run $3,000 to $8,000 or more per country at entry, with prosecution costs following in each one. Enter eight or ten countries across two or three families and a single quarter's IP spend can exceed everything filed to date. Broad international coverage is commonly cited at 10 to 15 times a US-only budget over a patent's life.
Startups get surprised by this cliff constantly, because the decision (filing the PCT) and the payment (national phase) are separated by two and a half years and usually one funding round. Put it in the financial model now.
Selection is the startup's real budget lever
A startup cannot outspend an incumbent on filings and should not try. The working strategy is one or two genuinely strong families on the inventions that make the company fundable and hard to copy, protected in the three to five countries where the market and the competitors actually are. In our engagements the highest-leverage spend at this stage is on deciding and documenting: which inventions justify a filing, written up so counsel drafts efficiently.
ipCapital Group does that selection and documentation work. We do not bill attorney or government fees, and we are a consultancy, not a law firm, so the filing budget itself goes to your patent counsel and the patent offices. Our job is making sure it goes to the right filings.
Related questions
Should we file before or after the raise?
Before, if the core invention will be exposed: pitching is risky disclosure territory, and a provisional is cheap insurance for the priority date. Investors also check whether you filed before public disclosure. Confirm timing with patent counsel; the US one-year grace period does not exist in most other countries.
Do investors actually scrutinize the patent budget?
Sophisticated ones check the portfolio against the story. One thoughtful family beats a scatter of thin filings in diligence, because diligence teams read claims, not counts.
What if we cannot afford to maintain everything we filed?
That is normal portfolio management, not failure. Every maintenance and annuity date is a decision point, and pruning assets that no longer map to the business funds the ones that do.
Can ipCG tell us which inventions to file on?
Largely yes: we run structured invention capture, score candidates against business value and the prior art, and deliver filing-ready disclosure documents to your counsel. The legal filing itself belongs to a registered patent attorney or agent.
