IP Protection for Startups: Patents, Trademarks, and Trade Secrets
When patents are worth pursuing versus when they're a distraction, how trademark registration works, trade secrets as a viable strategy, IP assignments from co-founders and contractors, and EU vs US basics.
Intellectual property protection divides founders into two camps: those who over-invest in it (spending $100K on patents before they have a product worth protecting), and those who ignore it until they need it (discovering during due diligence that their core IP isn't properly assigned to the company). The right approach is neither — it's targeted, staged, and tied to what actually creates competitive value in your business.
Patents: When They're Worth Pursuing
The patent system was designed for the invention economy of the 19th century. For software and most internet-era startups, it doesn't map cleanly to competitive advantage, and the cost-benefit calculation often doesn't work out.
The core patent tradeoffs:
Cost: A single US utility patent costs $15,000–$30,000 in legal fees from application to grant, takes 2–4 years to grant, and requires maintenance fees every few years to keep active. A European patent validated in multiple countries costs more. Building a meaningful patent portfolio is a multi-hundred-thousand-dollar exercise.
Time to protection: A pending patent ("patent pending") does provide some protection and deterrence, but you can't sue on an ungranted patent. Given 2–4 year timelines, the landscape you're protecting may have changed substantially.
Enforcement: Patents are only valuable if you can enforce them. Enforcement requires litigation, which costs $1M+ in the US and is similarly expensive in Europe. For most startups, you don't have the resources to sue a large competitor even if you have a valid patent.
Software patents specifically: The US has narrowed software patentability significantly through Alice Corp v. CLS Bank (2014) and related cases. In Europe, software patents are theoretically excluded under the European Patent Convention (though there's a workaround for "technical implementations"). Many software patents, if challenged, don't survive scrutiny.
When patents make sense for startups:
- Deep tech (biotech, materials science, hardware) where the core innovation is a genuine technical invention
- Situations where an exit acquirer will value the patent portfolio (common in pharma, medical devices, some semiconductor contexts)
- Defensive filing to prevent competitors from patenting around you, even if you won't enforce aggressively
- When you have genuine novel, non-obvious technical claims that survive the abstract idea exception
For most SaaS startups, the money and time spent on patents is better deployed on product development and customer acquisition.
Trademarks: Where Founders Delay Too Long
Unlike patents, trademark registration is relatively fast, cheap, and valuable — which makes it frustrating that founders routinely wait too long to file.
A trademark protects your brand — your company name, product name, logo, and distinctive brand elements — within a specific class of goods/services in a geographic territory.
In the EU: File through EUIPO (European Union Intellectual Property Office) for a European Union Trade Mark (EUTM), which covers all 27 EU member states. Filing fee starts at €850 for one class. Processing typically takes 4–6 months if there are no oppositions. One registration; 27 countries.
In the UK: File through the UK IPO. Separate from the EU post-Brexit. £200–£300 for one class.
In the US: File through the USPTO. ~$250–$350 per class for online filing. Processing takes 12–18 months but priority date is the filing date.
The most common founder mistake: waiting until you have a successful product before filing. Trademark rights in Europe are first-to-file (you get priority based on when you filed, not when you started using the mark). If a squatter or a competitor files your brand name before you do, you'll spend significantly more money in an opposition or cancellation proceeding than you would have spent just filing.
File your company name and product name as early as the brand is established and you're reasonably committed to it.
Doing a Trademark Search First
Before filing, run a clearance search to check whether someone else has already registered a similar mark in your class. A basic search using the EUIPO's eSearch and the USPTO's TESS databases is free. A comprehensive clearance search by a trademark attorney (which catches phonetically similar marks, design marks, and prior common law use) costs €500–€1,500 and is worth it before you've built significant brand equity.
Trade Secrets as IP Strategy
For many startups, trade secret protection is more practically valuable than patents — and almost entirely free.
A trade secret is any information that has commercial value because it's not known to the public and that you take reasonable measures to keep confidential. Classic examples: algorithms, model weights, customer lists, pricing formulas, manufacturing processes.
What makes trade secrets work:
- No application or registration — protection exists automatically when you treat the information as confidential
- No expiration — a trade secret lasts as long as it remains secret (vs 20 years for a patent)
- Broad coverage — you can protect any valuable information, not just patentable inventions
What makes them risky:
- No protection against independent development — if a competitor independently develops the same thing, they haven't infringed your trade secret
- No protection if the secret leaks — once it's public, it's gone
- Enforcement requires evidence of misappropriation — you need to prove someone took your secret improperly, not just that they know the same thing
To rely on trade secrets, you need to take active steps to protect the information: NDAs with employees and partners, access controls on sensitive technical documentation, confidentiality provisions in employment and contractor agreements, and clear internal policies about what information is confidential.
IP Assignments: The Foundational Step
All the trademark filings and patent applications in the world are useless if the underlying IP doesn't actually belong to the company.
At incorporation: Any IP created before the company existed — by the founders, in their personal capacity — must be formally assigned to the company. This is an IP assignment agreement, signed by each founder. It covers code, designs, inventions, and know-how developed in connection with the business idea.
From co-founders: If a co-founder later leaves without having signed an IP assignment, and they wrote significant code or invented something central to your product, you may not own that IP. This is a due diligence killer. Standard shareholders' agreements include IP assignment provisions; make sure yours does.
From contractors: Contractors do not automatically assign IP to you. Under most countries' laws, the IP in work created by an independent contractor belongs to the contractor unless there's a written agreement saying otherwise. Every contractor agreement should include a clear work-for-hire clause and IP assignment.
From employees: In most EU jurisdictions, employers automatically own IP created by employees in the course of their employment. But the boundaries are less clear for work done on personal time with personal tools — explicit IP assignment clauses in employment contracts remove the ambiguity.
These are the assignments that institutional investors check in due diligence. Clean IP ownership documentation is a must-have, not a nice-to-have, by the time you're in a Series A process. Founders approaching a fundraising process benefit from working through their IP situation with advisors who have been through due diligence before — a platform like Founderboard can surface the gaps in your IP posture before an investor's lawyers do.
