According to Federal Law No. 11 of 2021, an invention is considered to involve an inventive step if it is not obvious to a "person skilled in the art" based on the current state of technology, or prior art.
Invention has to be a creative leap, not just a logical extension. If a professional in your field looks at your idea and says, "That's the obvious way to go," it probably doesn't meet the criteria. It has to be an unconventional solution to a technical challenge.
According to the law, an invention must be "industrially applicable," meaning it can be physically produced or used in an industrial process. If it only exists as a concept in a notebook and cannot be built or utilized, it won't qualify.
