Innovative Start-ups entwickeln schnell – und veröffentlichen dabei oft (zu) früh: Pitch-Decks, Website, Pilotkunden, Messen, Github oder LinkedIn. Genau hier liegt das Risiko: Eine Offenbarung vor der Anmeldung einer Erfindung zum Patent kann die Patentfähigkeit gefährden. Die zeitliche Abfolge entsprechender Schritte muss daher vorab sinnvoll geplant werden, um sich die Chancen für einen späteren Patentschutz nicht selbst zu verbauen (wichtig: auch eigene Veröffentlichungen stehen einer späteren Patentanmeldung als Stand der Technik entgegen).
A good patent strategy does not have to be expensive or bureaucratic — it mainly needs to be early, focused, and aligned with your funding situation.
Why patents are more than just “protection against copying” for start-ups
Patents (and even patent applications) are often strategically relevant in early stages because they:
- make value visible (IP as an asset in financing rounds and cooperations),
- strengthen negotiation positions (licenses, partnerships, market access),
- signal professionalism (a traceable IP rationale instead of “innovative” as a buzzword).
Not every business model requires patents. However, anyone innovating technically (e.g., mechanical engineering, MedTech, technical processes, materials, software with a technical effect) should “think IP” from the very beginning.
The key: “First filing” — done right
What does “first filing” mean?
The first filing is the initial patent application for an innovation that establishes the filing date and priority. After that, the invention can be disclosed, and the international strategy and scope can be further planned within the priority period (typically 12 months) — for example by filing follow-up applications in additional countries or divisional applications covering specific sub-aspects.
A common mistake
“We’ll file once everything is finished.”
In the start-up reality, this often means: too late — because disclosures have already happened.
A practical approach
A first filing does not have to be “perfect”, but it must be substantial:
- the technical core and problem-solution concept should be clearly described,
- variants/alternatives should be considered, and
- sufficient detail should be included so the disclosure supports later prosecution.
Budget planning: making patents manageable instead of “all or nothing”
Instead of large one-off investments, an incremental, phased model is usually best for start-ups.
Phase 1: Idea/MVP (Pre-Seed)
Goal: secure the option for protection.
- IP screening: What is the core innovation, what is merely a feature?
- quick plausibility check against the prior art,
- first filing before the next major step into the public domain.
Phase 2: Pilot & product maturity (Seed–Series A)
Goal: align the scope of protection with product and market feedback.
- follow-up filings for improvements/variants,
- claims focus: protect what will be monetized,
- portfolio roadmap aligned with the product roadmap.
Phase 3: Scaling/internationalization
Goal: prepare markets and enforcement.
- international filing strategy based on markets/production/sales/competitors,
- competitor monitoring,
- contractual and documentation foundation for cooperations/licenses.
Core idea: not as many filings as possible, but the right filings at the right time.
Typical pitfalls in investor discussions (and how to address them)
1) “We have IP” — but the application does not cover the product
Investors check whether the application is substantively relevant or merely “marketing”.
Better: explain in 2–3 sentences what the technical core is and how the portfolio supports it.
2) Unclear ownership (freelancers, university, ex-employer)
Classic red flags: missing assignments, unclear inventor chain, external developers without clean transfer of rights.
Better: clarify early by contract (employment/consulting agreements, assignments, documentation).
3) No protection mix (patent vs. trade secret vs. trademark/design)
Some aspects are better protected as trade secrets, others as trademarks/designs for market presence.
Tip: make a conscious choice: What will be disclosed (patent/utility model) — what stays internal (trade secret) — what additionally secures market appearance (trademark/design)?
4) Freedom-to-operate (FTO) too late
Having your own patents does not automatically mean “freedom to operate”.
Better: plan FTO as a milestone in good time before market entry.
Conclusion
A start-up-ready patent strategy combines:
- first filing before any public disclosure,
- budget planning instead of cost shock,
- clear ownership and documentation,
- an IP story that fits your product and go-to-market roadmap.
