Answer:
Novel; patent; the inventor; sale; public.
Step-by-step explanation:
Patent can be defined as the exclusive or sole right granted to an inventor by a sovereign authority such as a government, which enables him or her to manufacture, use, or sell an invention for a specific period of time.

Basically, the three (3) main ways to protect an intellectual property is to employ the use of
I. Trademarks.
II. Patents.
III. Copyright.
One of the requirements for a patent is that the invention be new, or novel. An invention will not satisfy this requirement if it has already received a patent or been described in a printed publication, unless the publication was made by the inventor in the year before filing the patent application. In addition, if the invention was in public use, on sale, or otherwise available to the public elsewhere in the world, the invention is not patentable.
