Explain the concept and elements of patentability with the exclusions.

The patent = the invention's exclusive right (the limited-term monopoly in exchange for the disclosure — the invention's publication to the world). The patentability's three elements(the exam's core):1. Novelty (the new-to-the-world: the prior-art's absence — the absolute-novelty standard; the prior-use's-and-publication's destruction);2. Inventive step (the non-obviousness: the person-having-ordinary-skill's surprise — the obvious-to-try's bar);3. Industrial applicability (the utility: the making-or-using in any industry). The exclusions'catalogue (the TRIPS-and-national faces): the discoveries-scientific-principles-and- mathematical methods; the business methods; the plant-and-animal varieties' traditional bar (the UPOV's separate world — U6.4); the diagnostic-therapeutic-and-surgical methods; the immoral-and-ordre-public inventions. The types: the product-and-process patents (the process's reach into the product's proof — the reverse-burden's lore); the national's filing-types (the ordinary-and-the convention applications (the Paris priority's claim)); the PCT's international-route faces.
