If you’ve created something genuinely new and useful, a patent can be a powerful moat around your competitive edge. But how much does a patent cost in the UK, really?
In this guide, we break down the cost of a patent in plain English - including official UKIPO fees, typical attorney costs, renewal fees and international options - so you can budget with confidence and decide whether patent protection is the right move for your business.
We’ll also share practical ways to manage patent costs, common mistakes that make applications more expensive, and how patents fit alongside other intellectual property (IP) options like trade marks and licensing.
Why Patents Matter For Small Businesses
A granted UK patent gives you the right to stop others from making, using, selling or importing your invention in the UK for up to 20 years (subject to paying renewals). That exclusivity can help you:
- Protect your R&D investment from copycats
- License the technology to generate revenue
- Increase business valuation for fundraising or exit
- Negotiate stronger partnerships and distribution deals
If you’re weighing up patentability or the best route for your particular invention, speaking with an intellectual property lawyer early can save time and rework later.
What Is The Real Cost Of A UK Patent?
The total cost of patenting depends on the complexity of your invention, how many countries you want coverage in, and how much professional help you use. Broadly, you should budget across four buckets: official fees, professional fees, international filings, and ongoing renewals.
1) Official UKIPO Fees (The “Government” Fees)
Official fees payable to the UK Intellectual Property Office (UKIPO) are relatively modest compared to professional costs. As a ballpark, the combined filing, search and substantive examination fees are typically in the low hundreds of pounds spread over the first 12–18 months. There can be additional charges for longer specifications or other extras.
Because UKIPO fees can change, always check the latest schedule before filing. The bigger cost driver is usually the work required to draft, amend and prosecute your application.
2) Professional Fees (Drafting And Prosecution)
This is where most businesses spend their patent budget. Typical UK ranges are:
- Initial patentability review and strategy: roughly £500–£1,500, depending on scope
- Prior art search by a professional: roughly £800–£2,000+ (optional but often worthwhile)
- Drafting a UK patent application: roughly £3,000–£6,000 for a relatively simple invention; £6,000–£10,000+ for more complex tech, software-implemented processes or electronics
- Prosecution (handling UKIPO reports, amendments, arguments): plan for £1,000–£3,000+ over the life of the application, depending on objections and iterations
Each invention (and each drafter) is different, so treat these as indicative. If your product includes software or data-driven features, it’s worth considering whether aspects are better protected by patenting your app, trade secrets, or a combination.
3) International Protection (PCT And National Filings)
If you only need UK coverage, you can stop at the UK application. If you need protection in multiple markets, you have two main routes:
- File directly in target countries within 12 months of your first filing (claiming priority).
- Use the Patent Cooperation Treaty (PCT) to buy time (usually 30/31 months from your first filing) before entering national phases worldwide.
Expect international filings to multiply costs. As a rough guide:
- PCT filing: often £3,000–£5,000+ in professional fees plus international authority fees
- National phase filings: commonly £2,000–£5,000+ per country in professional fees and local official fees (some markets cost more)
Be strategic: prioritise markets where you manufacture, sell, or expect competitors to compete. You don’t have to file everywhere.
4) Renewal Fees (Keeping Your Patent Alive)
In the UK, renewals are due annually from the 5th year after the filing date. Official renewal fees start relatively low and increase each year. As a ballpark, they begin at around £70 in year 5 and rise gradually to roughly £600 by year 20, plus any service charges if an attorney pays on your behalf.
Build renewals into your long-term budget and be honest about whether the patent is still valuable each year. If a patent no longer supports your commercial strategy, you can let it lapse to save ongoing costs.
UK Patent Application Timeline And When Costs Fall Due
Here’s a practical, high-level timeline for a standard UK application and where costs tend to land:
Pre-Filing (0–2 Months)
- Patentability review and strategy discussion
- Optional prior art search to identify similar inventions
- Drafting the specification, claims and drawings
Costs incurred: professional fees for search and drafting.
Filing (Month 0)
- Submit UK patent application (to secure a priority date)
- Pay the UKIPO filing fee (often small and sometimes deferred briefly if needed)
Costs incurred: official filing fee, any final drafting costs.
Search And Substantive Examination (Months 6–18+)
- Request search and pay the search fee (often within 12 months)
- UKIPO issues a search report identifying prior art
- Request substantive examination and pay the examination fee
- Respond to examination reports; amend claims as needed
Costs incurred: search and examination fees; professional fees for prosecution and amendments.
Grant And Renewal (Typically 18–36+ Months)
- If the application meets requirements, the UKIPO grants the patent
- Pay any grant-related official fees
- Renew annually from year 5 onwards to keep the patent in force
Costs incurred: grant-related charges (if applicable); annual renewals from year 5.
International route? If you plan to file abroad, calendar your 12-month priority deadline (for direct filings) or the PCT national phase deadlines (usually 30/31 months). Those are the big cost “cliffs” for going global.
Ways To Manage And Reduce Patent Costs
Patents are an investment, but there are smart ways to control your spend without compromising protection.
1) Start With A Focused IP Strategy
You don’t always need to patent every feature. Identify the core inventive concepts that truly drive your advantage and focus your claims there. For brand and customer trust, consider a trade mark to protect your name or logo alongside any patent filings. You can register a trade mark to secure exclusive rights to your brand, and it’s usually cheaper and faster than a patent.
2) Stage Your Spend
- File in the UK first to secure your priority date while you validate market fit.
- Use the 12-month priority window (or PCT) to refine your product and decide which countries justify protection.
- Prepare an international shortlist before big deadlines to avoid rushed, expensive filings.
3) Keep Your Invention Confidential Before Filing
Public disclosure before filing can kill patentability - and waste your entire budget. Use a Non-Disclosure Agreement when discussing your invention with potential partners, suppliers or advisers. Make sure your team understands what they can and cannot share publicly.
4) Invest In Quality Drafting Upfront
A well-drafted application can reduce objections, shorten prosecution, and lower long-term costs. Poor drafting may save a little initially but lead to expensive amendments, narrower protection, or rejection later.
5) Consider Alternatives Or Complements To Patents
- Trade secrets: Keep “how it works” confidential (processes, methods, data). No official fees, but you must maintain secrecy with contracts and controls.
- Trade marks: Protect the brand customers recognise; you can also trade mark your logo for extra protection.
- Designs: If the visual appearance is what’s new, a registered design can be quicker and cheaper than a patent.
6) Use Commercial Tools To Monetise Or Share Cost
- Licensing: Monetise your patent by allowing others to use it in defined markets while you collect fees. Put a robust IP Licence in place to set scope, territory, royalties and quality control.
- Assignments: If you’re selling the IP or transferring it to a spinout, secure value with a clear IP Assignment.
These agreements help convert your IP into revenue - or make deals possible - even while patent applications are pending.
Budgeting: Patent Costs Vs Other IP Options
It’s sensible to weigh the cost of patents against other protection tools and your commercial goals. A typical first-year patent budget (search + drafting + filing + early prosecution) can range from ~£4,000 to £10,000+ depending on complexity. International filings will add substantially.
By comparison, many SMEs secure brand protection sooner, because it’s relatively affordable, fast, and underpins marketing and sales. If that’s part of your plan, consider whether to register a trade mark early so you can scale brand awareness confidently while your patent strategy progresses.
If your innovation is in software, data or UX, protection can be nuanced - some claims can be patented if they provide a technical contribution, while other aspects are better handled through confidentiality, contracts and brand protection. In these cases, a blended approach led by an intellectual property lawyer can keep costs aligned with value.
Common Mistakes That Increase Patent Costs
Avoiding these pitfalls can save significant time and money:
- Disclosing before filing: A public pitch, press release or trade fair demo without protection can destroy novelty.
- Filing too early: If the invention changes materially after filing, you may need a new application or complex claim strategy.
- Under-specifying the invention: A thin description gives you less room to amend claims, leading to narrow protection or avoidable objections.
- Over-claiming everything: Dozens of broad claims can trigger objections and extra fees; focused claims often prosecute faster.
- Missing priority and national phase deadlines: Late filings can require restorations or force you to abandon markets entirely (both are costly).
- Skipping commercial planning: Filing in countries where you won’t sell, manufacture or license drains budget with limited ROI.
If you’re collaborating with contractors or co-founders, make sure ownership is clear from day one. Your development agreements should ensure the company owns the resulting IP, and your core team should sign NDAs, assignment clauses and invention disclosure processes. When in doubt, speak to an intellectual property lawyer about a simple, workable IP policy for your team.
FAQs: Quick Answers On Patent Costs
How Much Does A Patent Cost In The UK?
For a straightforward UK-only application drafted by a professional, many SMEs budget in the range of £4,000–£10,000 across the first 12–18 months, including official fees and early prosecution. Complex inventions can exceed this. International filings multiply costs.
What Are The UKIPO Fees?
Official UKIPO fees cover filing, search, examination and eventual renewals. They’re generally modest compared to professional drafting and prosecution costs. Always check the UKIPO’s current fee schedule before filing.
When Do Renewal Fees Start?
In the UK, renewals are due annually from the 5th year after your filing date and increase each year until year 20.
Should I File A PCT?
A PCT can be a great way to defer large international costs while you test the market, but it adds its own filing cost. If you only need UK protection, you don’t need a PCT.
Can I Reduce Costs By Filing Myself?
You can file without a patent attorney, but patents are technical legal documents. DIY filings often lead to narrower protection or higher downstream costs to fix issues. For most businesses, investing in quality drafting upfront is more cost-effective long term.
Do I Need Contracts While I’m Patent-Pending?
Yes. Use NDAs for confidential discussions, ensure consultants and employees assign IP to the company, and put licensing terms in writing if you’re commercialising pre-grant. Consider a Non-Disclosure Agreement and speak with us about fit-for-purpose IP clauses in your team and supplier contracts.
Key Takeaways
- Plan for four cost areas: official UKIPO fees, professional drafting/prosecution, international filings, and annual renewals from year 5.
- A typical UK-only patent for a simple invention can run ~£4,000–£10,000 across the first 12–18 months; complexity and global filings increase budget.
- Protect confidentiality before filing - use a Non-Disclosure Agreement and keep public disclosures off-limits until you’ve secured a filing date.
- Be strategic: focus claims on what truly drives your advantage, and consider complementary tools like trade secrets and trade marks.
- Good drafting reduces downstream costs. A well-prepared application can mean fewer objections, quicker grant and stronger protection.
- Commercialise smartly with contracts: use an IP Licence to monetise and an IP Assignment when transferring ownership.
- If your innovation relates to software or platforms, assess which parts suit patenting versus confidentiality - our team can guide your approach to patenting your app and brand protection like trade marking a logo.
