Darren Mitchell

Partner - Patent Attorney

Darren works with both innovative and ambitious technology driven start-ups and the investors who provide the funding they need to progress. His extensive insight into the way both sides work allows Darren to instantly see the situation from his clients’ respective perspectives so that he can provide them with the very best advice.

For start-ups this means building the robust IP strategy that will ensure they secure investment and increase exit valuation. It means ensuring that technology driven businesses looking to attract a buyer or additional investment have an IP portfolio that is “due diligence ready” so sale or investment progresses smoothly.

For investors it means conducting comprehensive IP due diligence that stress-tests the assumptions others have made about valuation and uncovers any associated IP risks in the most pragmatic and cost-effective way.

This avoids investors being asked to pay over-the-odds for their stake or taking on unknown risks and liabilities. It also makes it much easier for them to integrate the target business into their portfolio.

Darren’s decades of experience protecting technological innovations as diverse as explosive detectors, performance apparel, and cardiac ablation devices, means he can quickly build trust and confidence between the parties as he leads them to a deal. He will show that underlying innovations are sound and can be protected, that IP is correctly managed, and that the risks relating to IP have been identified, evaluated and tackled.

Darren also has considerable experience before the UK Intellectual Property Office and overseas Patent Offices, both in relation to patents and designs. As a qualified Patent Attorney Litigator he has also been involved in complex multi-jurisdictional disputes.

Awards & Recognition

Darren is known to go ‘over and above’ for clients and they often say how enjoyable it is working with him. 


After (responsibly) enjoying real ale for many years, a gluten allergy forced Darren to explore the world of artisanal ciders. He continues to face this challenge with stoic resolve.
