Requirements: new, inventive and susceptible of industrial application

The law provides that an invention must meet certain requirements. First of all it must be new.: no one else may know of the invention. Once an invention has been made public, it can no longer be protected. Secondly, an invention must involve an inventive step: it may not be obvious. Thirdly, the invention must be susceptible of industrial application, which means that the industry must be able to produce or use it.
