Need help to formulate your application?
Patenting is a complicated 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.
