The R&D and IP settlement criterion for Innovator Founders

For founders building technical products, criterion (iii) looks like a natural fit for settlement. Research and development is often the whole point of the business. But the criterion has a second limb that is easy to overlook until late: an application for UK intellectual property protection. A business with years of genuine R&D and no UK IP application does not meet the criterion as the guidance describes it.

This article looks at criterion (iii) from the settlement section of the Home Office caseworker guidance "Innovator Founder" version 11.0 (4 August 2026). It covers what each limb asks for, why IP timing matters, and how to keep records your endorsing body can rely on.

The two limbs

Your settlement endorsement letter must confirm at least two of seven criteria. If R&D and IP is one of them, both limbs need to be in place when the endorsing body assesses you.

Limb one: significant R&D

The guidance does not, in the description we rely on, put a figure on "significant". That leaves the judgement with your endorsing body, which must be satisfied before it confirms the criterion.

What helps an endorsing body reach a view is a clear record. Consider keeping:

• A short R&D log: the technical questions you set out to answer, approaches tried, and results
• Spending on R&D, separated in your accounts where possible
• Who did the work, whether founders, employees or contractors
• Outputs: prototypes, datasets, technical reports, test results
• How the R&D relates to the business plan in your previous endorsement

The last point matters because the settlement letter separately has to confirm significant achievements against the business plan assessed in your previous endorsement. R&D that advances the agreed plan supports both confirmations; R&D on an unrelated side project helps far less.

Limb two: applied for UK IP protection

The criterion refers to having applied for UK intellectual property protection. Three points follow from that wording.

Applied, not granted. The description does not require the protection to have been granted by the time you apply for settlement. Keep proof that the application was made.

UK protection. The criterion names UK protection. If your business has only filed in other jurisdictions, take advice early from your endorsing body and an IP professional about whether that will be accepted for your case.

Relevance. It is sensible for the protection you apply for to relate to the R&D you are relying on. An IP application unconnected to the research is unlikely to make the overall case more persuasive.

Which form of protection fits your work is a question for an IP adviser, not for this article. The point for settlement planning is that preparing an application takes time, so if criterion (iii) is part of your plan, start that conversation well before year three.

Timing it against your settlement date

The settlement endorsement letter must be no more than three months old when you apply, and you need three years' continuous residence with your last permission being Innovator Founder. Work backwards:

See the three-month endorsement letter window for how to time the letter.

Pairing criterion (iii) with a second criterion

You need at least two criteria, and the same criterion cannot count twice. R&D-heavy businesses often have long pre-revenue periods, so the revenue criteria may be out of reach at three years. Combinations worth considering:

• R&D and IP + £50,000 invested and actively spent. Research often consumes investment, so the two can be evidenced from the same accounts, though they remain separate criteria. See the investment criterion.
• R&D and IP + jobs. If you have hired researchers or engineers in roles that meet the job tests. See the jobs criteria.

If you have co-founders on the route, the guidance says team members applying for settlement cannot share the same means. Ask your endorsing body how that applies if more than one of you wants to rely on the same R&D and IP.

Do not forget sustainability

A research-led business may be spending heavily with little income. The settlement letter must confirm the business is sustainable for at least the next 12 months, based on assets and expected income against current and planned expenses. Strong R&D does not replace that confirmation. Read the 12-month sustainability test alongside this article, and the full settlement checklist.

Key takeaways

• Criterion (iii) has two limbs: significant R&D activity and an application for UK IP protection.
• The wording refers to having applied for protection, not to protection being granted.
• There is no numeric threshold for "significant", so document your R&D in a form your endorsing body can assess.
• Start IP discussions early, because preparing an application takes time.
• Pair it with a different criterion, and remember the separate 12-month sustainability confirmation.
