A patent (in Dutch: ‘octrooi’) gives it's owner the legal right to prevent others from commercially exploiting their technical invention without their permission. An invention usually is a product or a process that provides, in general, a new way of doing something, or offers a new technical solution to a problem. 

In order to be patented, the invention must be novel, inventive and suitable for industrial application.


An invention is basically know-how that the inventor does not want to disclose until they have filed a patent application. However, how can you negotiate with future financial or business partners without disclosure? By storing your idea in a BIP SXM i-Envelope, you can prove that you had the idea at the date of filing. The BIP SXM i-Envelope issues a date stamp and, unless you choose to make it public, remains closed to third parties. You can, for example, mention the number of your i-Envelope in a non-disclosure agreement (NDA). This will give you the possibility to negotiate more freely with financial or business partners. If a potential partner discloses your invention, you will be in a better position to prove that they breached the non-disclosure agreement.

Do not disclose your invention until you have filed a patent application! If you reveal your invention to the public too early, it will no longer be considered novel and will become unpatentable.

What is the practical advantage?

A patent (in Dutch: ‘octrooi’) gives you the opportunity to prevent others from commercially exploiting your technical invention without your permission. If you are able to challenge infringement, this could eventually lead to a monopoly on the invention.

How long is it valid?

A patent is valid for a maximum of twenty years.

All patents contain information on the applicant and inventor, along with a description of the invention. All patents all over the world are used to describe innovative products and processes. This allows users to find answers to such questions as:

  • Does my invention already exist?
  • What products and techniques are there already?
  • Who are my potential customers and suppliers?
  • What are my competitors up to?
  • Who are my potential (commercial) partners and collaborators?
  • How do I decide on a strategic innovation policy?

NB. Patents are regulated by Kingdom Law.


What are the criteria for a Patent?

Patent applications must satisfy the following three criteria:

  • Novelty

    This means that your invention must not have been made public – not even by yourself – before the date of the application.
  • Inventive step

    This means that your product or process must be an inventive solution. It cannot be a solution that would be obvious to a skilled professional. Take the example of a different attachment method. Instead of welding the tubes of a swing together, they might be screwed together. This may well be a new method of making swings. But for someone involved in making them, it is too obvious a solution to be called an inventive step.
  • Industrial applicability

    This criterion implies that it must be possible to actually manufacture the new invention. In other words, you can apply for a patent on a new kind of playing card that is easier to hold than existing cards. But you can’t obtain a patent for an idea for a new card game.

These rules are laid down in the Patents Act 1995.

Maintenance fees


In order to maintain your patent rights, you must pay the first maintenance fee (€ 40) starting from the 4th year after filing. These costs increase every year. If you pay the maintenance fees annually, your patent will remain valid for a maximum of 20 years. Of course you have the choice to stop paying this fee before the maximum period of twenty years, the patent will then cease to be valid.
