The state of the art refers to all matter which has been made available to the public anywhere in the world, by publication in tangible form, sale or marketing.

b. - Inventive step

An invention involves an inventive step if it is not obvious to a person skilled in the art.

c. - Industrial application

The invention must be capable of industrial application, in principle, being made or used in any industry, whether manufacturing, handicrafts, mining, agriculture, or other.
