The patent

A patent protects an invention of a technical or chemical nature. In order for an invention to be protected by a patent, it must be new and inventive compared to the relevant prior art, and it must be susceptible of industrial application. A patent protects an invention for 20 years.

There are many different strategies to best protect an invention. For example, there is the possibility of filing a Swiss patent application. A Swiss patent application leads to a Swiss patent, which allows you to prohibit your competitor from copying your invention within Switzerland.

However, patents are national property rights. In other words, if you want your invention to be protected outside Switzerland, one or more applications must be filed abroad. To avoid having to file an application in every single country, it is possible to file a European patent application or an international patent application.

With a European patent, protection can be obtained in any country of the European Patent Convention. Currently, there are 38 countries (

With an international application, a single application can be filed with effect for currently 153 countries ( However, this application must be continued in each country where protection is actually to be obtained.

The costs

The preparation of a patent application costs about 4000 to 5000 Swiss francs for a simple invention. For a complex invention these costs can reach 10’000 to 12’000 Swiss Francs. In addition, the official fees incurred with the application must be paid.

Thus, for a moderately complex invention, the cost of a Swiss patent application is approximately 5’000 to 6’000 Swiss francs, and for a European patent application it is 8’000 to 9’000 Swiss Francs and for an international patent application approx. approx. 11’000 to 12’000 Swiss francs.
