In order for your invention to get a patent, it must meet certain requirements.

It must:

  • be new
  • possess inventiveness
  • be industrially applicable

Novelty: The invention must not have been known previously at the time the patent application was filed. It does not matter by whom or where in the world it has been published. The invention will be considered to have become known even it was you who used or published it.

Inventiveness: ‘Inventiveness’ or ‘inventive step’ means that the invention must differ significantly from anything that has been known previously. The solution may also not have been easily made by a person skilled in the ‘art’, the field of technology of the invention. This means that new ways of combining known methods or objects will not necessarily be patentable.

Industrially applicable: The requirement that the invention must be industrially applicable means that it must have a technical nature and technical effect and be reproducible.

A technical nature means that the invention must pertain to something tangible, such as a product or a process, and not just a theory, for example.

Technical effect means that the invention must function and that it must solve a problem in a technical manner. However, the effect does not need to be new or better than earlier solutions.

Reproducibility means that the results must be the same every time the invention is applied.

A patent can be valid for a maximum of 20 years. The validity of a patent can end for five reasons: The patent term has expired. The annual fee has not been paid to the Swedish Patent and Registration Office (PRV). The patent holder requests for the patent to no longer be valid. The patent is revoked after opposition. The patent is declared invalid by a public court.

You can get basic help at the Swedish Patent and Registration Office (PRV), such as how to file an application and what fields are compulsory. PRV does not help with technical descriptions and advanced knowledge about your invention. If you need help with this, you can turn to a patent attorney, for example.

Here is a guide for how to complete your application, step by step.

You can find patent information in the Swedish Patent Database and other databases. Here, you can search patents and read the documents in full text.

A patent is an exclusive right for the holder to use an invention in various ways. A Swedish patent is only valid in Sweden and you must yourself apply for patents in other countries. If the invention is mainly intended for the Swedish market, it may be enough to have a Swedish patent. You must then be aware that anyone has a right to manufacture, sell or use your invention abroad.

This question is complex and the answer depends on many factors. We have therefore prepared cost examples to provide a good picture of the costs. All fees for applying and maintaining patents are presented on our fee list.

The Swedish Patent and Registration Office (PRV) fee list for patents

The payment is to be made through Bankgiro.

All information on fees and payment for patents can be found here.

If you failed to pay for a patent, and it has thereby lapsed, there are very limited possibilities to revive the patent. If you discover, within 12 months of the extended deadline for paying the annual fee, that the annual fee has not been paid, there is a possibility.

Through a special procedure according to Section 72 of the Patent Act, you can request that the Swedish Patent and Registration Office (PRV) declare that a late annual fee is to be considered to have been paid on time.

The prerequisites in order for PRV to be able to grant such a request are that the patent holder can show that he or she took all due care required by the circumstances, meaning that the unmade payment may not be due to carelessness, ignorance or that one changed one’s mind. Accordingly, a reinstatement of the patent is not automatic.

There are three different alternatives:

A. An alternative is to file an international Patent Cooperation Treaty (PCT) application. An international PCT application can lead to a protection in around 140 countries, including Sweden. You can file your PCT application via the Swedish Patent and Registration Office (PRV), via the European Patent Office (EPO) or directly with the World Intellectual Property Organization (WIPO). At the same time, you choose which authority, PRV or EPO, will examine your application.

B. Another alternative is to send in separate patent applications directly to the individual countries’ patent offices where you want patents. This is a good way if you know that your market is in certain, relatively few countries. There are also a number of non-European regional patent authorities.

C. A third alternative is to file a regional application to the EPO (a European Patent Convention, EPC, application). With an EPC application, you can get protection in more than 40 countries in Europe, including Sweden. This may be favourable if, for example, you are certain that your invention is new and that the market for the invention is not in Sweden.
