What is intellectual property, actually? A founder's plain-English guide

Introduction

Most founders build something before they understand the legal rules for owning it. That's the normal order. You have an idea, you sketch it out, you write some code or build a prototype, and only later does someone ask the awkward question: "so who actually owns this?" The answer involves intellectual property. The term gets used loosely in startup conversations to mean anything from a patent to a brand to a piece of code, and that looseness is part of why founders get confused. IP isn't one thing. It's four different legal tools, each designed to protect a different kind of intangible asset, each with different costs and different time horizons. Choosing the right one for the right asset is the whole game. This article is for founders who've heard the word "IP" but have never had it properly explained. No prior legal knowledge assumed.

Why you cannot own an idea (and what you can own instead)

A common misconception: "my idea is my IP." It isn't. You can't own an idea. Ideas aren't legally protectable anywhere in the world. What you can own is a specific expression, implementation, or distinctive identifier of that idea.

Imagine two founders have the same idea: a subscription service for curated coffee. Neither owns the idea. What they can own separately is their specific brand name and logo, their specific website and marketing copy, their specific packaging design, and potentially their specific roasting or blending technique. The idea is free. The expressions of it are protected.

This is the foundation of everything else. Once you understand that IP protects specific implementations rather than ideas, the four types start to make sense as a system.

The four types of IP, without the jargon

Patents: for inventions

A patent protects a technical invention. If you have invented a new mechanism, chemical process, medical device, algorithm with a technical effect, or manufacturing technique, a patent gives you a legal monopoly on using it for up to 20 years, in exchange for publicly describing how it works.

Patents are the most powerful IP right for technical startups, and the most expensive to obtain. They require a formal application, a search against everything ever publicly disclosed before your filing date, and examination by a patent office. They protect things that're new, inventive, and useful in an industrial sense.

Typical cost: a few thousand euros for a European filing, rising to tens of thousands for global coverage over time. Typical timeline: filing in days to weeks, grant in three to five years.

Trademarks: for names, logos, and brand identifiers

A trademark protects the signs that distinguish your business in the market: your brand name, your logo, your tagline, sometimes even a distinctive colour or sound. It prevents other businesses from selling similar products under a confusingly similar identifier.

Trademarks are relatively cheap and renewable indefinitely. A trademark that's actively used can last forever. They're usually the first IP right a startup formally registers, typically around the time of launch or first funding.

Typical cost: a few hundred euros for a European Union trademark. Typical timeline: four to six months for registration.

Copyright: for creative and written work

Copyright protects original creative expression: text, images, music, video, and importantly for startups, software code. Copyright is automatic. The moment you write the code or the copy, you own the copyright. No registration required in Europe.

Copyright protects the specific expression, not the underlying idea. Your codebase is protected the moment you write it, but copyright doesn't stop a competitor from writing different code that does the same thing. That's why copyright alone is rarely enough for a technical startup. The functional innovation needs a patent.

Typical cost: zero (automatic). Typical timeline: instant.

Trade secrets: for information you keep confidential

A trade secret is any commercially valuable information that derives its value from being kept confidential: customer lists, proprietary formulas, source code you never release, pricing algorithms, internal methodologies. Coca-Cola's recipe is the canonical example.

Trade secrets are free, indefinite, and require no registration. But they evaporate the moment the information becomes public. You protect them through contracts and internal practices: NDAs, employment agreements, access controls.

Typical cost: zero to file, but ongoing cost in contracts and controls. Typical timeline: forever, as long as the secret holds.

Which one do you actually need

For most technical startups, the honest answer is two or three of them at once.

A trademark for the company name and logo. Copyright (automatic) over the code, website, and content. A patent if there is a genuinely novel technical invention at the core of the product. Trade-secret protection for anything deliberately kept private.

The decision that most affects defensibility, and the one most founders defer too long, is the patent decision. Trademarks and copyright are largely hygiene. A patent's a strategic asset: it raises valuations, unlocks grants, and blocks competitors from copying the technical thing that makes the product interesting.

How the IP decisions stack up over time

A typical trajectory for a technical European startup:

Pre-launch: register the trademark. Make sure copyright in founder-written code is assigned to the company, not to the individual founder.

Pre-fundraise: file a patent on the core technical invention if there is one. This is the highest-leverage IP action available at the early stage.

Post-Series A: formalise trade-secret protection through employment agreements and NDAs. Consider a second patent filing on subsequent inventions.

Scale-up: build a small portfolio. Consider international coverage via the PCT system. Think about licensing.

The one IP decision that cannot wait

Trademarks, copyright, trade secrets: important, but not acutely time-sensitive. The patent decision is the one where waiting has an asymmetric downside.

Patents go to the first to file, not the first to have the idea. Every day you delay is a day a competitor can file the same invention and take the priority date. Every public disclosure you make before filing is a potential problem. In European patent law, there's no grace period: show the world how your invention works before filing, and you may have permanently forfeited the right to patent it.

If you've built anything technically novel and you haven't yet thought about patenting, the right first move is a patentability check. It takes two minutes and tells you honestly whether what you've built is eligible for protection. If it is, the window to act is now, not after the next funding round.

Frequently asked questions

What is intellectual property and why does it matter for startups?

Intellectual property is the legal system for owning intangible assets: inventions, brand identifiers, creative works, and confidential information. For startups, it matters because it determines who legally owns the technology, brand, and content you build. Without the right IP protections in place, a competitor can copy your product, your name, or your code with limited recourse.

‍

What is the difference between a patent and a trademark?

A patent protects a technical invention, giving you an exclusive right to use it for up to 20 years. A trademark protects a brand identifier, such as a company name or logo, and can be renewed indefinitely. Patents protect what your product does. Trademarks protect how people recognise you. Most startups need both.

‍

Does copyright automatically protect my software code in Europe?

Yes. Copyright in software code is automatic in Europe from the moment you write it. No registration is required. However, copyright only protects the specific code as written. It does not stop a competitor from building the same functionality in different code. For that, you need a patent on the underlying technical invention.

‍

Which type of IP should a startup prioritise first?

For most technical startups, the priority order is: patent first if there is a novel technical invention, because the window to file is time-sensitive and public disclosure can destroy the right permanently. Then trademark, to protect the brand before launch. Copyright is automatic and requires no action beyond ensuring assignment clauses are in founder and contractor agreements.
