Before you apply for a patent
Check if someone else has protected a similar invention
You may be wasting time and money developing technology that has already been invented or patented? It is therefore a good idea to check which rights exist in Norway, and avoid spending time and energy developing a product that others have the rights to.

We can carry out a preliminary search for you

Need help to formulate your application?
Patenting is a complex field where it is easy to make mistakes. If you have limited experience with patenting or limited time to work on your application, you should consider using a professional patent agency or patent attorney. A patent agency can help you prepare and formulate your patent application. Strict requirements and deadlines apply. A patent agency will assist you in monitoring these deadlines, and various payments such as annual fees. A list of professional patent agents can be found on the website iprhjelp.no: Rådgiverdatabasen (in Norwegian only) or on Google.
If you are planning to apply abroad
If you have filed a patent application in one country (e.g. Norway) and wish to file an application for the same invention in other countries, it is important to note that this application must be filed within 12 months of the first application. This ensures that you have the same "priority" (LINK) date, and that the novelty aspect of your invention will be assessed as if it had been filed at the same time as the first application.

Patent applications and national security considerations
A small number of patent applications may have significance to the defence of the realm and hence become subject to directions under the Norwegian Patents Act, section 71. You may file a patent application for this type of invention. However, special conditions apply with regard to filing, communication and handling of these applications.
