Do you need a patent to win EU grant funding?

In brief: A patent is not mandatory to secure EU grant funding. However, applicants, particularly deep-tech companies applying to the EIC Accelerator, must demonstrate a credible and defensible strategy for protecting and exploiting their innovation. Patents can provide valuable evidence of technological novelty and defensibility, but they are neither necessary nor sufficient. Depending on the technology and business model, an effective IP strategy may combine patents with trade secrets, proprietary know-how, software rights, exclusive licences, data assets or contractual protection. Evaluators will also consider whether the applicant owns or controls the relevant IP and has sufficient freedom to commercialise the proposed solution. Under the 2026 Work Programme, the EIC Accelerator offers grants of up to €2.5 million, combined, where appropriate, with an EIC Fund investment of €1 million to €10 million. Applicants must have completed TRL 5, while grant-supported activities generally cover further development and validation at TRL 6–8. At this stage, broad claims of being “breakthrough” or “disruptive” are unlikely to withstand scrutiny unless they are supported by convincing technical evidence, a clear comparison with the state of the art and a robust IP strategy. 

Every founder pursuing EU funding hears the same warnings: competition is intense, the process is demanding and success rates are low. What receives far less attention is the role that IP can play in the evaluation: not simply as a legal asset, but as part of the evidence that the technology is genuinely differentiated, commercially defensible and capable of generating impact. 

We sat down with Alice Mussard, a grants advisor at Evolution Europe whose team has helped clients secure more than €200 million in EU funding, to examine how patents and wider IP strategies influence EU grant applications. 

If you are building a deep-tech company and considering both public funding and private investment, this is an important part of any IP-for-fundraising conversation. EU evaluators and investors may approach IP from different perspectives, but both want to understand the same fundamentals: what makes the technology different, whether the company can protect that advantage and whether it has a credible route to market.

Two very different kinds of funding, two very different questions about IP

Founders often treat public funding and private investment as part of the same fundraising process. The two are connected, but evaluators and investors look at IP through different lenses.

A VC typically wants to know: Can this company protect its competitive advantage, scale the business and generate a return on our investment?

For the EIC Accelerator, the questions are broader: Is the technology genuinely breakthrough and significantly better than existing alternatives? Does the company have an adequate IP strategy, a credible route to market and the potential to create or transform a substantial market?

Horizon Europe evaluators take a slightly different perspective. They assess whether the project advances beyond the state of the art, contributes to the call’s expected outcomes and impacts, and presents a credible strategy for exploiting its results. In collaborative projects, ownership, access rights and the ability of consortium partners to use the project’s results can be just as important as patent ownership.

This distinction is often underestimated. A relevant patent or patent application can strengthen the case for technical novelty and defensibility, but it is not conclusive evidence that a technology is disruptive or commercially valuable. A filed application may not yet have been examined, while even a granted patent does not prove market uniqueness, customer demand or freedom to operate.

A patent is therefore a useful signal. Not a verdict. 

The strongest applications combine an appropriate IP strategy with technical validation, quantified comparisons against the state of the art, a clear competitive landscape, evidence of market need and a credible exploitation plan. That combined evidence is what makes a breakthrough claim convincing.

Where patents actually show up in an EU grant application

EU innovation funding often follows the Technology Readiness Level scale, from fundamental research at the earliest TRLs to commercial deployment at TRL 9. The appropriate IP strategy should evolve alongside the technology. But this does not mean filing a patent as early as possible in every case.

Early TRL — EIC Pathfinder, typically TRL 1–4: At this stage, applicants are not normally expected to hold a granted patent. The technology and its potential applications may still be evolving, so filing too early can result in claims that fail to cover the final innovation. Nevertheless, teams should already understand the relevant prior art, clarify ownership of background IP and establish how future results will be protected and exploited.

Timing matters. An enabling public disclosure, through a scientific paper, public presentation, demonstration or unrestricted pitch deck, may undermine the novelty required for a European patent application. By contrast, sharing information in a confidential grant proposal or with consortium partners subject to appropriate confidentiality obligations does not automatically constitute public disclosure. Patent advice should therefore be sought before publicly revealing the core invention.

Mid-to-late TRL — EIC Accelerator, activities at TRL 6–8: At this point, the IP case becomes much more concrete. The EIC Accelerator supports companies that have already validated their technology in a relevant environment and are ready to advance demonstration, market readiness and scale-up.

Applicants are expected to present adequate IP protection and a sound IP strategy, but this does not necessarily mean holding a granted patent. Depending on the innovation, protection may include pending patents, trade secrets, proprietary know-how, software rights, exclusive licences or other contractual arrangements. Applicants should also demonstrate that they own or control the IP required to commercialise the solution and have considered freedom to operate.

EIC technology experts will test whether the claimed breakthrough is credible and significantly better than existing alternatives. An unsupported statement that a technology is “unique” will rarely survive that scrutiny. The strongest applications combine a defensible IP position with technical results, quantified benchmarking, a robust analysis of the state of the art and a credible route to market.

The co-financing test, and why patents help you pass it

Here is a detail that often confuses first-time applicants: the EIC Accelerator grant component generally covers up to 70% of eligible project costs. The remaining 30% must be financed by the beneficiary from its own resources. This does not mean that applicants must already have secured private investment or national funding before applying.

For companies requesting the EIC investment component, however, the ability to attract additional capital remains important. The EIC will assess whether its participation is necessary to overcome a genuine funding gap and whether it can help mobilise other investors. Existing investor interest, previous fundraising or credible discussions with potential co-investors can strengthen the application, but they are not automatic prerequisites for EIC support.

This is where IP and fundraising strategies begin to intersect. A credible IP position can reassure both EIC evaluators and private investors that the company has the right to commercialise its technology and a realistic way to defend its competitive advantage. But a patent alone does not make a company investable.

The strongest case combines appropriate IP protection with convincing technical validation, a significant market opportunity, a scalable business model, a capable team and a realistic financing strategy. Leaving the IP discussion until the end can create problems in both grant evaluation and investor due diligence, precisely when the company needs its technology, commercial and financing narratives to reinforce one another.

The three failure patterns worth knowing before you apply

Across her work with clients, Mussard has seen the same weaknesses undermine otherwise promising applications.

• A funding wish instead of a funding strategy. Public grants and private investment should not be treated as disconnected opportunities. Applicants need to explain what the EIC funding will finance, why those activities cannot be funded on acceptable terms elsewhere and how the project fits into the company’s wider financing and scale-up plan. Not every applicant must already have private investors, but the financing strategy must be credible.
• No market evidence to support the commercial case. A patent or patent application may support the company’s IP and defensibility strategy, but it does not prove that customers need the solution. Nor does commercial traction prove technological disruptiveness. The two questions require different evidence. Strong applications support their technical claims with validation data and quantified benchmarks, while demonstrating market demand through pilots, letters of intent, customer engagement, partnerships or early sales.
• A team unable to connect the technology with the business. During the EIC jury interview, whether conducted remotely or in another format specified by the EIC, the team must be able to defend the full proposal under demanding questioning. This includes the technology, market opportunity, competitive landscape, IP position, business model, implementation plan, financial needs and scale-up strategy.

The CEO should normally lead the discussion, but the company should select the strongest combination of team members permitted under the applicable interview rules. The objective is not for one person to know every technical detail. It is to demonstrate that the management team collectively has the expertise, credibility and alignment required to bring the innovation to market.

A practical timing rule

If there's one number to take away: Mussard recommends starting the EIC Accelerator application process three to six months before submission, and, if you're planning to work with a grants advisor, reaching out at least three months ahead of your first submission. Patent strategy needs to run on a similar or earlier clock, or even earlier timeline, rather than being added hastily once the deadline is approaching . An enabling public disclosure made before filing may destroy the novelty required to obtain patent protection in Europe, so sequencing matters as much as the substance.

Building an IP-for-fundraising checklist

Before you put together an EU grant application (or, frankly, before your next investor conversation), it's worth running your own quick patent valuation and ip due diligence pass:

• Have you identified the core innovation, and is it protected through the most appropriate combination of patents, trade secrets, know-how, software rights or contractual arrangements?
• Would an independent technical expert find your breakthrough claim credible when compared with the state of the art and existing alternatives?
• If you have filed a patent application, do its claims cover the technology and competitive advantage at the heart of the proposal, or only a peripheral feature?
• Does the company own or control the IP required to develop and commercialise the solution?
• Have relevant third-party rights and potential freedom-to-operate risks been considered?
• Has the core innovation been publicly disclosed before filing through a paper, presentation, demonstration or unrestricted pitch deck? If so, what may remain protectable?
• Can the team explain its IP position clearly, including what is protected, who owns it and why the chosen strategy supports commercialisation? 

This initial groundwork can begin internally, before engaging a grant advisor or IP specialist. However, conclusions concerning patentability, claim scope, public disclosure and freedom to operate should be validated by a qualified IP professional.

A well-prepared IP strategy strengthens the company’s credibility with EIC evaluators and juries, Horizon Europe experts, investors and potential acquirers. The objective is not simply to possess a patent strategy for startups, but to demonstrate that the company understands, controls and can defend the competitive advantage to any credible to any audience, EU juries, VCs, or acquirers down the line.

The bigger pattern: patents as an "investable" signal, not just a legal shield

The central message from the conversation with Mussard was not simply about grant mechanics. It was that a deliberate IP strategy signals that a founder is building a defensible business, not only an interesting research project. That matters whether the audience is an EIC jury, a private investor or a potential strategic acquirer.

Public funding supports ambitious innovation that can generate significant economic, societal or strategic value, particularly where technological uncertainty, long development cycles or market failures make private financing difficult to secure on its own. But “high-risk” and “unprotectable” are not the same thing. Evaluators and investors both want to understand whether the company can control and defend the competitive advantage underpinning its innovation.

A relevant patent or patent application can be a valuable part of that evidence when patent protection is appropriate. However, the strongest signal is a coherent IP position: clear ownership or access rights, appropriate protection mechanisms, consideration of freedom to operate and a credible plan for exploiting the innovation commercially. A patent is one possible component of that strategy, not a substitute for it.

FAQ

Do I need a granted patent to apply for the EIC Accelerator, or is a pending application enough?
Neither a granted patent nor a pending patent application is automatically required. The EIC Accelerator assesses whether the applicant has adequate IP protection and a sound IP strategy. A relevant patent application may strengthen that case, but its value depends on factors such as claim scope, ownership, commercial relevance and the territories covered. Other protection mechanisms, including trade secrets, know-how, software rights and exclusive licences, may also be appropriate. 

Does having a patent guarantee EU grant funding? 
No. IP is one input among several, No. A patent is only one element of a much broader evaluation. Depending on the programme, evaluators will consider factors such as technological ambition, advancement beyond the state of the art, technical feasibility, market opportunity, expected impact, commercialisation strategy, team capacity and implementation quality. A strong patent position may support the novelty and defensibility case, but it cannot compensate for weaknesses elsewhere in the proposal. 

Is EU grant funding only for university spin-outs? 
No. EIC and Horizon Europe funding opportunities are available to different types of organisations, including startups, SMEs, research organisations, universities, public bodies and, under certain instruments, larger companies. Eligibility and consortium requirements depend on the specific programme and call. A startup can therefore qualify whether its technology originated in a university laboratory or was developed independently within the company. 

How does this differ from IP due diligence for a VC round? 
There is considerable overlap. Both investors and EU evaluators may examine IP ownership, protection, freedom to operate and the company’s ability to defend its competitive advantage. A private investor focuses primarily on risk, scalability and the potential return on investment. EIC evaluators also assess whether the innovation is breakthrough, whether it can create significant European impact and whether public support is justified. In collaborative Horizon Europe projects, evaluators additionally consider how project results will be owned, accessed, disseminated and exploited by the consortium.
