An invention shall be considered to have an inventive level if it is not apparent to the connoisseur in an obvious manner from the state of the art. The solution does not have a level of inventive, if the connoisseur does not go beyond the usual technical progress and is clearly and logically from the state of the art, ie. A specialist who knows the closest state of the her technique without creative input in a professional and routine way to come to a proprietary solution using the usual logic of reasoning. Inventive levels do not have a solution to:

  • Change only the size of the product that makes it portable;
  • A combination of several known solutions or elements, provided that this does not lead to a change in their function or to a more favourable effect than the sum of the partial results;
  • Changed components to known equivalents.
