A patent protects a specific solution to a technical problem. The patent gives exclusive rights for a limited period of time during which you can deny competitors the right to use the same solution for as long as the patent remains in force.

What is patent protection?

A patent is a documented exclusive right to an invention. This exclusive right can last for a maximum of 20 years. During this period, you will have exclusive rights to produce, import and sell the invention/product which you have patented. The invention must be described as a specific solution to a technical problem. It must be completely new and cannot have been referred to publicly before you submit your application for a patent (e.g. it cannot have been presented at a trade fair or referred to in an industry periodical). It must also differ significantly from previously known technology within the industry.

What is the duration of a patent?

A patent can normally be held valid for up to 20 years, starting from the date on which you submit your application. The patent must be renewed every year by paying an annual fee.

When should you consider applying for a patent?

Developing products can often be a time-consuming and expensive process.

The application process for patents is also time-consuming, so obtaining a patent is often most relevant for products which will remain on the market for many years, and for procedures or applications which will be used for a reasonably long period of time. A patent is not necessarily profitable for your invention, but it can be a good idea to consider the need for such protection. 

If you want to check if your invention is a new one, you can order a preliminary search from the Norwegian Industrial Property Office.

Employee inventions

Employees generally have the same rights to their inventions as other inventors. However, subject to certain conditions, the Act on employee inventions gives the employer the right to take over an invention. This only applies to patentable inventions. This does not mean that you have to apply for a patent, but the conditions for being granted a patent must be met.

The employer's right to take over an invention is determined on the basis of the employee's duties within the business, and what agreement the employee has entered into with the employer. If an employer wishes to take over an invention, the employee may be entitled to compensation.
