What Is a Patent?
As defined by the United States Patent and Trademark Office (USPTO): A [US] patent for an invention is the grant of a property right to the inventor, issued by the Patent and Trademark Office. A patent refers to a right granted to anyone who invents or discovers any new and useful process, machine, article of manufacture, or composition of matter, or any new and useful improvement thereof.
Moreover, a patent is a property right that gives the patent holder the right, for a limited time, to exclude others from making, using, offering to sell, selling, or importing into the United States the claimed invention in exchange for a full disclosure of the invention. In simplified terms, a patent is a way of protecting an invention (any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof).
Therefore, without a patent, anyone can legally make, use, sell or import your invention.
Note: Ideas are not patentable, but rather the knowledge of how to make and/or use the idea is patentable.
To be patentable the law specifies three primary patentability requirements wherein the subject matter of the invention must be:
• Useful – To have utility as in an invention must be capable of some beneficial use.
• Novel – The invention must be new (different from the prior art) and an invention is not new if it has been described in a printed publication, known or used by others, or has been in public use or for sale. If an invention is not new, then the invention is not patentable (i.e., anticipated by the prior art).
• Non-obvious If the differences between the invention sought to be patented and the prior art (what is known) would have been obvious to a person having ordinary skill in the art then the invention is obvious and not patentable.
Example: Obvious non-patentable subject matter includes the substitution of one color for another, or changes in size or obvious changes or improvements over the prior art.
