What IP documentation do EU investors require from startups?

EU investors conducting due diligence typically require: (1) IP ownership proof: evidence that the company, not individual founders, owns the core technology, designs, and content; (2) IP assignment agreements: signed and dated agreements from all founders and key contributors who created IP before or during employment; (3) IP creation timeline: version-controlled development records, qualified electronic timestamps on key milestones, or patent priority dates establishing when IP was created; (4) Trademark and patent registrations: filings in EU markets; (5) Non-disclosure and non-compete agreements with all parties who had access to proprietary IP. Qualified electronic timestamps from an eIDAS QTSP are increasingly used to satisfy the IP creation timeline requirement at low cost.

How do EU data protection rules (GDPR) affect startup IP protection?

GDPR (EU Regulation 2016/679) intersects with IP protection when the IP involves personal data: user data, customer databases, AI training datasets containing personal information, or research data. Under GDPR Art. 5, personal data must be processed lawfully, fairly, and for specified purposes. If a startup's IP consists of or relies on personal data, the legal basis for that data processing must be documented and maintained. Qualified electronic timestamps on data processing agreements, consent records, and GDPR documentation establish a clear legal timeline for IP built on personal data. This is critical for due diligence by EU investors who face joint liability for portfolio companies' GDPR compliance.

Should startups file patents or use trade secrets to protect technology in the EU?

The choice depends on: (1) Reverse-engineerability: if competitors can replicate your technology from the product alone, a patent is more protective (patents make it illegal to independently recreate the invention); if the technology can be kept secret, trade secret protection may last longer (patents expire in 20 years); (2) Cost and timeline: EU patents (via EPO) cost €10,000 to €50,000+ including translations and maintenance, take 3 to 5 years, and require public disclosure; trade secrets have no upfront cost but require active confidentiality measures; (3) Market strategy: for deep-tech where you plan to license technology to large companies, patents are essential; for B2B SaaS where the moat is execution and data, trade secrets may suffice. Qualified electronic timestamps serve both strategies: they establish creation date evidence before a patent is filed and document trade secret existence.

What is the EU Trade Secrets Directive and how does it help startups?

The EU Trade Secrets Directive (2016/943/EU), implemented in all EU member states, provides a harmonised framework for protecting trade secrets, including startup algorithms, processes, and know-how. It defines a trade secret as information that: is secret, has commercial value because it is secret, and is subject to reasonable steps to maintain its secrecy. The Directive gives holders of trade secrets the right to prevent misappropriation and seek civil remedies across all EU jurisdictions. For startups, the key requirement is proving that secrecy measures were in place. Qualified electronic timestamps on confidential documentation, combined with access logs and NDAs, provide the evidential basis to claim trade secret protection under the Directive.

How should a startup assign IP from founders to the company before raising EU investment?

IP assignment should happen before external investment closes. The process: (1) Identify all IP created by founders (code, designs, content, algorithms, brand assets) from before and during their work for the company; (2) Draft an IP assignment agreement specifying what is transferred, from whom, for what consideration (often nominal consideration is sufficient if founders receive equity); (3) Sign the agreement with qualified electronic signatures, which creates a legally binding contract and establishes the transfer date; (4) Apply a qualified electronic timestamp to the executed agreement, which proves the assignment date for future disputes; (5) Update the company's IP register. EU investors will review this documentation; gaps, missing signatures, or unclear ownership chains are common reasons for investment delays or reduced valuations.

En avril 2025, une startup fintech amsterdamoise a atteint l'etape du term sheet avec un capital-risqueur munichois. L'offre portait sur EUR 4 millions pour une valorisation pre-money de EUR 20 millions. L'equipe juridique de l'investisseur a ouvert la due diligence avec une seule question : pouvez-vous prouver quand votre algorithme central a ete cree et qu'il appartient a la societe et non a l'ingenieur fondateur a titre personnel ? Le CTO a produit un depot GitHub, un dossier Google Drive partage et un export Slack. Les avocats ont passe trois semaines a examiner ces elements, puis ont recommande a la VC de reduire la valorisation de 30 % pour tenir compte du risque PI non quantifie. L'operation a finalement ete conclue a EUR 14 millions de pre-money. Le cout d'une documentation PI qualifiee manquante : EUR 1,8 million de valorisation implicite perdue.

La propriete intellectuelle est l'actif le plus precieux qu'une startup apporte dans un tour de financement. C'est aussi le plus souvent sous-prepare. Les equipes fondatrices passent des mois a peaufiner le deck et le modele financier, pour decouvrir en due diligence que leurs preuves de propriete ne satisfont pas les normes juridiques requises par les investisseurs et leurs avocats.
