Unity of Invention

In most patent laws, unity of invention is a formal administrative requirement that must be met by a patent application to become a granted patent. Basically, a patent application can relate only to one invention or a group of closely related inventions. The purpose of this requirement is administrative, as well as financial. That is, the requirement serves to preclude the option of filing one patent application for several inventions, while paying only one set of fees (filing fee, search fee, examination fee, renewal fees, and so on). Unity of invention also makes the classification of patent documents easier.

When a patent application is objected to on the ground of a lack of unity, it may be still considered for patent protection, unlike in the case where the invention is found to be lacking novelty. A divisional application can usually be filed for the second invention, and for the further inventions, if any. Alternatively, a patent prosecutor may make a technical argument that there is unity of invention.

    I therefore, the prisoner in the Lord, beg you to lead a life worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, making every effort to maintain the unity of the Spirit in the bond of peace.
    Bible: New Testament, Ephesians 4:1-3.

    Art expresses the one, or the same by the different. Thought seeks to know unity in unity; poetry to show it by variety; that is, always by an object or symbol.
    Ralph Waldo Emerson (1803–1882)

    “Art” is an invention of aesthetics, which in turn is an invention of philosophers.... What we call art is a game.
