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.

“The gifts he gave were that some would be apostles, some prophets, some evangelists, some pastors and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until all of us come to the unity of the faith and of the knowledge of the Son of God, to maturity, to the measure of the full stature of Christ.”
—Bible: New Testament, Ephesians 4:11.
“As the unity of the modern world becomes increasingly a technological rather than a social affair, the techniques of the arts provide the most valuable means of insight into the real direction of our own collective purposes.”
—Marshall McLuhan (1911–1980)
“For this invention of yours will produce forgetfulness in the minds of those who learn it, by causing them to neglect their memory, inasmuch as, from their confidence in writing, they will recollect by the external aid of foreign symbols, and not by the internal use of their own faculties. Your discovery, therefore, is a medicine not for memory, but for recollection,—for recalling to, not for keeping in mind.”
—Plato (c. 427–347 B.C.)
