IP budget: what to file at pre-seed

1. Core idea and who it's for#

Patent costs follow a steep, predictable curve :

• Month 0: the first filing (a provisional or first application) is cheap.
• Month 12: the PCT application costs a few thousand dollars.
• Month 30 or 31: national-phase entry is where the bill multiplies, with one set of fees, translations and attorneys per country.
• After that: prosecution and renewals continue for years.

At pre-seed, the discipline is to buy time cheaply, spend on drafting quality, and push the expensive country-by-country decisions until you have the money and the market evidence to make them.

Three rules of thumb:

1. Spend on the first draft, not the filing fee. The provisional or priority application sets what you can claim later. A thin, rushed provisional saves money now and can cost you the patent. Official fees are small, and the attorney's drafting time is the real cost and the real value.
2. File where the value is, not everywhere. Most deeptech startups end up in 3–6 jurisdictions: usually the US, Europe and the home country, plus one or two that matter for manufacturing or customers, such as China, Japan or Korea. Use the landscape (2.19) and the go-to-market plan to choose.
3. Budget 30 months ahead, and match the spend to your rounds. The PCT's 30- or 31month national-phase deadline usually lands after the seed round. Plan it so the big bill falls after the raise, not before.

Who this is for: pre-seed founders deciding how much to spend on patents in the first two to three years, and in what order. It is especially useful if a university is paying for patents under the licence (2.07), because you'll inherit those costs and decisions.

2. Evidence: official fees and typical total costs#

First filing: official fees are small.

The PCT international phase, at month 12. You pay three fees: a transmittal fee, the international filing fee and the search fee (WIPO).

• The international filing fee was CHF 1,435 for up to 30 pages in 2025, plus CHF 16 for each extra page (UpCounsel, citing WIPO).
• Search fees range from about CHF 150 to CHF 2,000 depending on the searching authority (WIPO FAQ).
• At the USPTO, the transmittal fee is $285, or $114 for small and $57 for micro entities (USPTO).
• Reductions are available for individuals, small entities, applicants from lower-income countries and electronic filing (WIPO).

In total, expect roughly $4,000–$7,000 in official fees, plus $2,000–$5,000 in attorney fees for the PCT filing, depending on the searching authority and on how much redrafting you need.

National phase, at month 30 (US) or 31 (India and the EPO): the big step. At this point each country charges its own fees and needs local attorneys, and many need translations (Patsnap). European official fees alone are significant. From 1 April 2026:

• the European search fee is €1,595;
• the examination fee is €2,010;
• the designation fee is €720;
• the grant and publication fee is €1,135 (Finnegan).

Rough planning numbers for total cost to grant per jurisdiction, including attorney fees, vary widely with complexity:

• US: often $15,000–$30,000 or more;
• Europe: $20,000–$40,000 or more, before validation and renewals;

• India: often a few thousand dollars, with startup concessions;

• China and Japan: $10,000–$25,000 each, including translation.

Treat these as planning ranges and get real quotes.

What it adds up to. A single invention taken into five jurisdictions often costs $80,000– $150,000 or more over 5–7 years , and most of that comes after month 30. That's why the first filing and the PCT are cheap options to keep open, and national phase is the real investment decision.

3. Method: a filing plan and a 30-month budget#

Step 1. Rank your inventions. List each invention, from the quarterly IP review (2.18), and give each a tier.

• Tier 1 — core: without it there's no company. Patent it broadly and file internationally.
• Tier 2 — important: improvements, a second product line, a manufacturing method you can detect being used. File a priority application, and decide at month 12 whether to go to the PCT.
• Tier 3 — defensive or speculative: consider defensive publication, keeping it as a trade secret (2.18), or a cheap home-country filing only.

Step 2. Choose where to file first, and how.

• US provisional if the US is your main market and you're a US company.
• UK filing for a real search report early and cheaply.
• Indian provisional, with the startup fee concession , for Indian companies. Remember that foreign-filing permission is needed for inventions made in India (2.05).

Whichever route you take, pay for a strong draft that covers several embodiments and fallback positions.

Step 3. Use the 12 months well. File follow-up provisionals as new data comes in. A US provisional can't be extended, so merge them into one PCT or non-provisional at month 12. Run the landscape and an initial FTO on the Tier 1 product (2.19, 2.06).

Step 4. At month 12, file the PCT for Tier 1, and maybe Tier 2. Choose the searching authority with care: the EPO is often valued for search quality, other authorities can be cheaper. Use the search report and written opinion to tighten the claims.

Step 5. At about month 24, decide on the national phase. Do it six months before the deadline. Decide country by country:

• markets for the first product;
• where competitors manufacture;
• where you could realistically enforce;
• where acquirers care.

Budget for each country. Consider the Unitary Patent , which covers most EU member states with one renewal fee, plus separate UK and Swiss patents if needed.

Step 6. Match the spend to the money. Put the national-phase money into the seed budget, explicitly, and tell investors. If the seed round slips, decide early which countries to drop.

Worked example (illustrative): a 30-month IP budget#

An Indian-incorporated photonics startup has one Tier 1 invention and one Tier 2. It plans to sell in the US and Europe, and manufacture in India.

The total of roughly $32,000–$39,000 over 31 months fits a typical pre-seed budget, with most of it falling after the seed round. US and EPO prosecution, grant and validation follow from year 3 to year 5 at a further $30,000–$60,000, paid for by later rounds.

4. India / US / UK: ways to save money#

India#

• The DPIIT startup concession cuts official patent fees by about 80% to the individual or startup rate, and allows expedited examination , which can bring grant in about a year. Get DPIIT recognition before you file.
• SIPP. The Startup Intellectual Property Protection scheme, which reimbursed facilitator fees, ended for new filings after 31 March 2026, so budget for attorney fees in full.
• Foreign-filing permission (section 39) is needed before filing abroad first for inventions made in India. Building it into the timeline costs nothing. State schemes and incubators sometimes reimburse patent costs. Ask your incubator (1.11).

US#

• Small-entity status (fewer than 500 employees, including affiliates) gives a 60% discount, and micro-entity status an 80% discount. Micro status has income and filing-count limits, or applies through university employment. Check eligibility carefully, because claiming it wrongly can be serious.
• Provisionals are cheap placeholders, but the quality of the draft decides what you can claim later.
• Track One prioritised examination costs more but gets a decision in about 12 months, which is useful before a Series A.
• University-paid patents: under many licences the company reimburses past and future patent costs (2.07). Negotiate to defer or cap the reimbursement until the seed round.

UK#

• A UK first filing costs about £405 in official fees for filing, search and examination after April 2026, and gives an early search report. It is often the cheapest informative first step.
• Patent Box applies a 10% corporation-tax rate to profits from patented inventions. That doesn't matter at pre-seed, but it is part of the case for UK or EP patents covering the UK later.
• Unitary Patent and the UPC. One European patent with unitary effect covers 18 or more EU states with a single renewal fee. The UK is not included, so UK cover comes through the EP validation or a UK national patent.
• Innovate UK grants can sometimes cover patent costs as an eligible project expense. Check the competition rules.

5. Scripts, mistakes, related playbooks and sources#

Scripts#

Asking your attorney for a phased quote:

"Please quote three stages separately: a strong priority filing with fallback claims, a PCT at month 12 with the EPO as searching authority, and national phase in the US, at the EPO and in India at month 30. Please flag any page or claim fees we can avoid by drafting carefully."

Telling investors:

"Our IP spend to month 31 is about $35,000. National-phase entry, which is about $15,000–$20,000, falls in month 30, after the seed round. It's a line in the use of funds. We're filing in the US, Europe and India because those are our markets and where manufacturing happens."

To the TTO about patent costs under the licence:

"We'll take over prosecution and future costs. Can past patent costs be reimbursed after the seed round, or in instalments, and can we agree together which countries to file in at national phase?"

Common mistakes#

1. A cheap, thin provisional that doesn't support the claims you need later.
2. Filing everywhere at month 30 without a market rationale, which wastes money that should go into product.
3. Missing the 30- or 31-month deadline. It's usually not recoverable, and the rights are lost.
4. Filing abroad first from India without permission. This can mean penalties and a risk to the Indian patent.
5. Claiming micro-entity status wrongly in the US.
6. No budget line for patents. Patent costs surprise the CFO in month 30.
7. Patenting Tier 3 inventions that would be better kept secret or published defensively.
