What does it mean that the solution involves an inventive step?
If a solution involves an inventive step it means that the set of its technical features is not obvious to a specialist in a given field. A technical solution can be patented if it meets certain criteria, e.g. the premise of an inventive step. This means that its development was not possible by merely combining several previous solutions, tests, and features, but required the creative input of the inventor or researcher.
