How long does it take to file a patent in Europe?

Introduction

Filing takes days to weeks on a platform, or two to four months through a traditional firm. Granting takes three to five years. Most of a patent's legal value is available from the moment of filing, not the moment of grant. These are two entirely different timelines, and founders who conflate them end up either delaying their filing or giving up prematurely.

This article separates them and explains which deadlines actually affect your business decisions.

‍

Filing vs. granting: what is the difference?

Two timelines matter, and they are entirely different.

• Time to filing: how long from "we want to file a patent" to "the application is filed at the patent office". This is the operational timeline. Platform: days to weeks. Traditional firm: two to four months.
• Time to grant: how long from filing to a granted patent. This is the examination timeline. Typically three to five years. You do not control it; it depends on the EPO's examination backlog.

Most of what matters legally attaches to the first timeline. The second is real but largely runs in the background.

‍

How long does filing take through a traditional firm?

A traditional patent firm typically takes two to four months from first contact to filing:

• Week 1-2: Initial call, conflict check, engagement letter, retainer invoice.
• Week 3-4: Kick-off meeting for invention disclosure, often delayed by scheduling.
• Week 5-6: First draft of the application produced by the attorney.
• Week 9-12: Revision rounds, client review, finalisation.
• Week 13-16: Final sign-off and filing.

The time is not spent on drafting. It is spent on scheduling, sequential review, and billing cycles. Actual drafting work is perhaps 10-20 hours. The rest is overhead.

‍

How long does filing take through a platform?

A platform like ptntpwr compresses the same process significantly:

• Day 1-2: Founder completes the guided wizard.
• Day 3-5: AI maps prior art and produces a structured draft for attorney review.
• Day 5-8: Attorney reviews, revises, and produces an attorney-grade draft.
• Day 8-14: Founder review, revisions, final sign-off.
• Day 14-21: Filing at the EPO or other office.

Total: roughly two to three weeks, not two to three months. The compression comes from eliminating sequential scheduling bottlenecks, not from reducing attorney work. The attorney still spends the hours. The hours just do not wait for calendar slots.

‍

Why does filing speed matter?

Patent rights go to the first to file. In a first-to-file system, a three-month delay is not just a scheduling inconvenience. It is three months during which another company could file the same invention and take the priority date. Similar inventions from independent teams arriving at similar times is normal, especially in fast-moving fields.

The difference between a two-week filing timeline and a three-month filing timeline can be the difference between owning the invention and being blocked by it.

‍

Does the grant timeline actually matter for startups?

Once filed, the EPO takes three to five years to grant a typical patent. During this time, your application is "pending". Pending is a legally meaningful status.

A pending application gives you:

• The priority date, worldwide, from the moment of filing.
• The ability to cite it in funding applications, investor pitches, and commercial negotiations.
• A block on competitors patenting the same invention.
• Legal uncertainty for anyone thinking of copying, which often acts as a practical deterrent.

For most startups, pending status provides 90% of the commercial benefit of a granted patent, years before grant arrives.

‍

The dates that actually need to be in your calendar

• Month 12 from filing: deadline to file PCT or direct national extensions if you want international coverage. Miss this and your international options close.
• Month 30 from priority (PCT route): deadline to enter national stages in individual PCT countries.
• Annual renewal fees: start at month 24 and continue for the life of the patent. Missing a renewal is a common, avoidable way to lose a patent.

Your patent attorney or platform should track these and send reminders. If they do not, switch providers.

‍

What is accelerated examination and is it worth it?

The EPO offers a programme called PACE that accelerates examination, typically bringing grant forward by one to two years. It is free to request. It makes sense when:

• You need a granted patent quickly for a specific commercial reason (e.g. litigation, a deal that requires grant status).
• You are confident the application will grant with minimal prosecution.

For most early-stage startups, accelerated examination is not the priority. Securing the filing date is.

‍

Conclusion

Filing a patent in Europe is a weeks-to-months task. Granting is a years-long background process. The priority date is locked at filing, and for startup purposes, that is the date that creates legal rights, investor signal, and competitive blocking. Do not confuse the two. Do not delay filing because grant feels distant. Most of what you need becomes available the day you file.

File your patent in days, not months. Fixed pricing, no scheduling delays.

Frequently asked questions

‍

How long does it take to get a patent granted in Europe?

From the date of filing, a European patent typically takes three to five years to be granted by the EPO. This timeline is determined by the EPO's examination backlog and the complexity of the application. However, the priority date, which is the legally critical date for establishing your rights, is secured on the day you file, not the day you receive the grant.

‍

What is the difference between a patent filing date and a grant date?

The filing date is when your application is submitted to the patent office. It establishes your priority date and immediately blocks anyone else from patenting the same invention. The grant date is when the EPO formally approves your patent after examination, typically three to five years later. Most of a patent's commercial and legal value, including investor signalling and competitor deterrence, is available from the filing date.

‍

What does "patent pending" mean and what rights does it give you?

"Patent pending" means your application has been filed and is under examination. It gives you a legally recognised priority date worldwide, the ability to cite the application in investor and commercial contexts, and a deterrent effect against potential copiers. Once the patent is granted, you can enforce your rights retroactively back to the filing date. Pending status is legally meaningful and commercially useful from day one.

‍

What is the PCT and when should a startup use it?

The Patent Cooperation Treaty is an international filing system that allows you to file a single application covering 150-plus countries simultaneously. It extends your decision window to approximately 30 months from your original filing date before you must commit to specific countries. Startups should consider a PCT filing if they have international commercial ambitions and want to keep multiple markets open without committing to country-by-country costs at month 12.
