Key property rights

Patent and utility model
A patent is considered to be the key technical property right. Due to the complex and precise examination procedure, the granted patent as a monopoly right is of very high importance in the industry. It serves to secure the company’s market position and the proprietary know-how. In addition, the term “patented” indicates the high quality of your invention.
The most important prerequisites for the patentability of an invention are:
- Novelty
- Inventive step
- Industrial applicability
When the patent is granted, the property right is valid for a maximum of 20 years from the date of filing.

Trademark
Trademarks are used to identify the goods and services of a company so that they can be distinguished from similar goods and services of other companies.
The trademark is your company’s fingerprint!
It serves as a hallmark of quality, an advertising medium or an indication of the country of origin of your goods and services. Trademarks are versatile and can be registered as word components, picture elements, three-dimensional images or as colors. The duration of the protection period is initially 10 years and can be extended as often as desired.

Design
Designs serve to protect two-dimensional objects, such as wallpaper or fabrics, and three-dimensional shapes, such as furniture, accessories, or cars.
If an invention lacks the technicality required for a patent, it is by all means possible to protect the design of the product or a part of the product. The design is therefore to be seen as a completion of the technical property rights. Upon registration, the owner has the sole right of use and may prohibit use by third parties.
The design has a maximum protection period of 25 years.
