When it comes to entrepreneurship, one of the concerns that arises from the outset is how to protect an idea from investors or competitions. The fear that a third party will appropriate an innovative concept without having made the effort to develop it is as common as it is legitimate. Therefore, if you are about to launch your start-up or have a promising idea in the pipeline, it is essential that you take legal and strategic measures from the outset.
How can you protect an idea from investors?
To begin with, we must say that an idea on its own, without development or concrete form, cannot be registered or protected as such. Current laws do not provide for the protection of abstract concepts. This means that you cannot patent a simple business notion or a general approach. Spanish legislation, in particular Article 4 of the Patent Law, makes it clear that economic methods, business plans, general ideas and software as such are not patentable.
So, does this mean that you are unprotected? Not at all. Although the raw idea cannot be registered, there are effective tools to protect its specific manifestations and prove your authorship.
Protect the key elements of your project
The first step in protecting an idea from investors is to identify which parts of your project can be registered. For example, if your idea is embodied in creative content (such as texts, presentations, graphic or audiovisual design, or even developed software), you can take advantage of the protection offered by copyright. This right is automatically generated upon creation, but to reinforce its legal effectiveness, it is advisable to register the work in the Intellectual Property Register, which you can do in person or online.
The same applies if you have a logo, trade name or graphic trademark that you wish to protect. The same applies to inventions or utility models involved in the idea. In these cases, we are talking about intellectual property, and the way forward is to register them with the Spanish Patent and Trademark Office (OEPM). This not only proves authorship or ownership, but can also serve as evidence in the event of a legal dispute. We will mention key points in some of these cases:
Trademark and logo
Registering a trademark with the OEPM (Spanish Patent and Trademark Office) is one of the first recommended actions. Before doing so, it is advisable to carry out a search to ensure that the name does not conflict with already registered trademarks. This step also applies if you want to register at European level (with the EUIPO) and avoid problems in wider markets.
Patents and utility models
If your project involves an innovative technical development, a patent or a utility model may be the best option for protecting an idea from investors. Specifically, to patent an invention in Spain, it must be truly new, it must not have been published anywhere in the world prior to the application, and it must have a specific utility. The State of the Art Report will help you check whether your invention already exists or whether you can proceed.
Web domains
Although it may seem secondary, securing your project’s domain is essential to preserving your digital identity. At ISERN Patents and Trademarks, we are official registrars for .es and .eu domains, as well as being able to register any territorial or generic domain. It is important to seek legal advice in order to obtain the best domain name for your trademark.
Accredit authorship in public or visible media
On the other hand, if your idea is already reflected on a website, in an application or even in a physical product, you can include simple mechanisms to record your authorship. Adding a legal notice to your website that clearly identifies the owner of the project, or placing labels with your name and the date on the product, are simple but useful ways to prove that you were the first person to develop it. In reality, they do not guarantee absolute protection, but they can help you in the event of a dispute.
Use confidentiality agreements to protect an idea from investors… but do so wisely
One of the most recommended legal instruments for protecting an idea from investors is a confidentiality agreement, better known as an NDA (Non-Disclosure Agreement). This document establishes that the individuals or entities that sign it—partners, potential investors, collaborators, etc.—may not disclose or use the shared information without your consent.
Specifically, the NDA is especially useful when you want to explore a collaboration, seek funding, or file a more detailed business model. Precisely because it protects information that is not yet on the market and that may be key to your competitiveness. In this particular case, we can include strategies, formulas, algorithms, monetisation ideas, among others.
However, you must be realistic. Many investors, especially venture capital funds, accelerators, or business angels, are reluctant to sign an NDA when you are only going to file your pitch or explain a general idea. They do not take it as a sign of mistrust, but rather as standard practice. In fact, these entities receive dozens of proposals every month and do not want to be legally bound by something they are just getting to know. Even so, if after that first contact the investor shows genuine interest, that will be the ideal time to propose signing the agreement.
Include intellectual and industrial property clauses: a necessary step
Any contract related to your project — whether with partners, employees, freelancers or suppliers — must contain a clause that expressly regulates intellectual property and industrial property rights. It is not enough to rely on the measures you take and general legislation to protect an idea from investors. Including a clear clause specifying that all rights to the trademark, product, website or content belong to the start-up (and not to those who execute or develop them) gives you extra coverage.
Although the law already establishes that authorship belongs to the creator, putting it in writing avoids misunderstandings and protects your position in the event of possible disputes. You can also limit the use of that property by third parties and even establish the conditions for a future licence if you wish. This is especially relevant in agreements with developers, agencies or designers who may be involved in the creation of essential elements of the business.
Blockchain and AI: technological allies to protect your ideas
Incidentally, emerging technologies are also opening up new avenues for protecting intellectual property. The use of blockchain, for example, allows you to generate immutable proof of authorship, digitally sealing a creation with a date and time on a blockchain. This type of certification is useful for proving that an idea or content existed on a specific date, without the need to resort to official registers. At ISERN, we have developed our e-Proof tool to register proof of use through blockchain technology.
On the other hand, artificial intelligence tools can also help monitor unauthorised use of your assets, such as images, texts or trademarks, alerting you if someone is using them without your permission on the internet.
