Shortly for Utility models

The main differences between utility models and patents are the following:


  • The requirements for acquiring a utility model are less stringent than for patents. The"inventive step" or "non-obviousness" may be much lower or absent altogether. 


  •  The term of protection for utility models is shorter than for patents


  • The registration process is often significantly simpler and faster


  • Utility models are much cheaper to obtain and to maintain


In some countries the protection can only be obtained for certain fields of technology and only for products but not for processes.
