Application and validation

A patent is an exclusive right that protects a new product, working method or technology. A patent allows the inventor to benefit from his invention, forbidding competitors to copy the invention. A patent is granted by the government offering the inventor the possibility to act against companies copying the patented invention. Competitors are thus kept at a distance.

Patent applications

Patents are national rights. Each patent only provides protection in one single country. So basically protection must be requested wherever protection is desired. NLO will be pleased to arrange both national and international applications on your behalf, so there is no need for you to contact the patent authorities yourself.

Within the first 12 months – the priority year – from submitting the first patent application, a continuation application may be submitted for another country or region on the basis of the first patent application.
