Your moat: defensibility that assessors and investors believe

"Moat" is the investor's word for what stops a rival copying you once the idea is shown to work. Assessors ask the same question as "freedom to operate", "barriers to entry" and "how you will protect and exploit the outputs". By the end you can write a truthful moat paragraph for a grant, a deck and a tender, and know which claims to drop.

The reality

Nobody scores the word "moat". Innovate UK scores your grasp of "any similar innovation identified and its current limitations" and whether barriers to entry are "identified and addressed"⁷; Sequoia wants your direct and indirect competitors and "a plan to win"⁹.

How it is judged

Freedom to operate (FTO) means you can make and sell the product without infringing anyone else's patents or trade marks. Evidence "can include results of patent searches, literature surveys and competitor analyses"⁸: say who searched, when, where, and what they found.

The EIC Accelerator requires a "Freedom to Operate analysis" with the full proposal, and from 2026 a technology expert "fact-checks, verifies claims cross checking with third party sources"¹⁰. An EIC evaluator since 2010, in a deck from about 2023 (before the 2026 rules), lists weak novelty claims: "No other innovation ever before has achieved such a result" and "X product is the first and only"¹¹.

A benefit is not a moat: the seven powers

Hamilton Helmer defines Power as "the set of conditions creating the potential for persistent differential returns". Each of his seven pairs a benefit (why you earn more) with a barrier (why a rival cannot copy it)². Write both halves or you have described a feature.

Helmer's Power Progression sets the timing. At origination, before the market takes off, only Cornered Resource and Counter-Positioning are open: "no lasting benefits of leading the pack". Network, Scale and Switching Costs arrive at take-off; Process Power and Branding at stability, once explosive growth ends (Helmer's rule of thumb: when it falls below 30 to 40% a year)².

So the honest line for a grant-stage company is: "We hold an origination-stage power (named) plus IP (stated, with its FTO result), and the project builds the next barrier (named, dated, measured)."

Test every network-effect claim

NFX calls network effects the strongest of "the four remaining defensibilities in the digital age, including brand, embedding, and scale" and sorts them into 16 types in five categories: direct, two-sided, data, tech performance and social¹. Run its tests before an assessor does.

• Value alone or value together? If a customer gets full value without any other user, there is no network effect. Name what the tenth customer adds to the first.
• Viral growth is not a network effect. "Network effects are not viral effects": virality is cheap acquisition, not defensibility¹.
• Data effects need a usage-to-data loop. The effect is strong only "if data is really central to the way the product benefits users"; where usage does not generate the data, "there is no network effect; it's merely a scale effect" (NFX's example is Experian)¹. "Proprietary AI" without a proprietary data loop is a scale claim, and a small one.
• Asymptotic effects are weak. When each extra user adds less value, a rival can match you with a smaller network (NFX's example: ride-hailing)¹.
• Multi-tenanting. If users can sit on a rival's network at the same time, the moat is thin unless you build lock-in, especially on the supply side¹.

Evidence switching costs, data, regulation and know-how

Switching costs work against you first: "Do not underestimate the inertia barrier… It is often preferable to stick with the status quo even if a better solution exists, because it is a known pain versus an unknown potential gain"⁸. Show how your first customers get over the incumbent's switching costs before you claim your own.

IP: state the position, not the hope

Patents count when you give the number, the status and an FTO result. "Patent pending" with no FTO search proves you filed, not that you can sell. Trade secrets and know-how count when they are documented and access-controlled; "secret sauce" does not. Do the first prior-art look yourself on Espacenet (150m+ documents) or Google Patents (120m+ publications), both free⁵⁶, then pay an attorney to confirm it.

Innovate UK allows an IP contribution of up to £7,500 per SME in eligible project costs, for filing new project IP; trade marks are ineligible and an unused amount cannot be moved to other costs⁴. The Intellectual Property Office (IPO) part-funds an IP Audit under IP Advance: "£2,250 (including VAT)", with the business contributing "£750", for trading businesses with fewer than 250 staff whose growth depends on IP (GOV.UK page published 8 October 2026)¹⁹. In 2025/26 the audit gave a bespoke report and a follow-up meeting, and "funding is not guaranteed"³; 342 SMEs took one that year²⁰.

What they accept and what they discount

Accepted:

• patents, granted or filed, with a stated FTO result (who, when, where, finding)
• documented, access-controlled trade secrets or know-how
• an exclusive data source or partnership, clause and term stated
• workflow embedding with numbers (integrations, data history, migration effort)
• approvals or certifications, with the time and cost to replicate
• a model the incumbent cannot copy without hurting its own revenue

Discounted:

• "first-mover advantage" or "speed" alone
• "proprietary AI" without a proprietary data loop
• "network effects" where a user gets full value alone
• "patent pending" with no FTO result
• "no competitors": the form asks for similar innovations "including those close to market or in development"⁷; the status quo is always one
• "first and only" and other superlatives without a benchmark¹¹

Peter Thiel, per Blake Masters' notes on his Stanford class: "find a small target market, become the best in the world at serving it"; owning a market takes "some combination of brand, scale cost advantages, network effects, or proprietary technology"¹⁶. Small and dominant is a story a reader can check; large and 1% is not.

Write the paragraph

Each version has five parts: the nearest alternative and its limit; the benefit, quantified; the barrier, named; the IP position with its FTO result; the next barrier with a date. Keep the numbers identical across every answer.

Innovate UK, Approach and innovation

The nearest similar innovation is [product or approach] from [company or
research group], which [limitation, quantified, source]. Ours achieves
[metric] against their [metric] (benchmark: [who measured, when]). The
difference holds because [barrier: exclusive licence / counter-positioned
model / data loop], which [competitor] cannot replicate without [cost or
damage]. IP: [patent number or application, status]; a freedom-to-operate
search by [firm] on [date] across [territories] found [result]; know-how in
[area] is documented and access-controlled. By month [n] the project adds
[certification / integrations / data loop], measured by [metric].

A deck slide

Title: Why this holds: [the barrier, in six words]
Left:  alternatives, including "do nothing", and what stops each following
Right: barrier today (named power, evidence); barrier at scale (named
       power, date, metric)
Foot:  IP [status, FTO result]. Exclusivity [partner, term].

A tender's "why us"

You asked for [requirement, in your words]. Our [approach] delivers
[outcome], evidenced by [named contract, date, measured result]. The
difference comes from [capability only we hold: approval / accredited
process / tool], which gives you [lower risk / faster / cheaper],
measured as [KPI we will report, frequency]. [Named person] owns it.

Score yourself before they do

Write "no" where it is true. Innovate UK Business Connect: "Don't claim too much – the assessor knows what is possible"⁸.

Pitfalls

• "First mover." Being early is a date, not a barrier; at origination there are "no lasting benefits of leading the pack"². Name the asset being first gave you, or drop it.
• "No competitors." The status quo, the spreadsheet and the research group two years behind you are competitors; name them and quantify their limits⁷.
• "Patent pending" as proof. A filing proves a filing. Give the FTO result, or date the search in the project plan.
• Brand confused with awareness. Branding is a willingness to pay more, built by "a long period of continual investment"². Followers are not a moat.

Checklist

• Nearest similar innovation named, its limitation quantified and sourced
• Each claimed advantage written as benefit plus barrier
• Every power claimed is available at your stage, or is dated as a plan
• Any network-effect claim passes the value-together, data-loop and multi-tenanting tests
• Patent number, status and FTO search (who, when, territories, result) stated; know-how controls described
• Exclusivity clauses, approvals and integrations quoted with term, cost or count
• The incumbent's inertia addressed before your own switching costs are claimed
• "First mover", "no competitors", "first and only", "unassailable" deleted
• Same benchmark numbers in the Approach, Market and Route to market answers
• Patent filing (up to £7,500 per SME) budgeted if planned; IP Audit requested if eligible

Questions

What is a moat in a grant application?

A benefit plus a barrier: something that makes your product better or cheaper, and a reason rivals cannot copy it. Innovate UK scores it as evidenced differentiation and freedom to operate, not as the word itself.

Do I need a patent to win an Innovate UK grant?

No. The guidance asks how you will protect and exploit the outputs, which can be "know-how, patenting, designs or changes to your business model". What loses marks is a protection claim without evidence.

What is freedom to operate?

Freedom to operate (FTO) means you can make and sell your product without infringing other people's patents or trade marks. The evidence is a search of patents, literature and competitors with a stated date, territories and result.

How do I know if I really have network effects?

Ask whether a customer gets full value alone. If yes, you do not. A data advantage counts only if ordinary usage generates the data and the data is central to the product's value. Viral growth is not a network effect.

What does the IP Audit cost and how do I get one?

Under IP Advance the IPO pays £2,250 (including VAT) and the business pays £750 (GOV.UK, October 2026). In England you apply through Innovate UK Business Growth, which paused new requests outside its existing programmes at October 2026; ask your growth hub or a BIPC for the current route. Funding is not guaranteed.
