Section 101 of Title 35 (U.S. Code)

Section 101 of Title 35 of the U.S. Code defines what can be considered patent-eligible inventions. It states that a patent can be granted for new, useful, and non-obvious processes, machines, manufactures, or compositions of matter, or improvements of them. However, laws of nature, natural phenomena, and abstract ideas are not patentable. This section provides the fundamental criteria for determining whether an invention qualifies for patent protection, ensuring that patents are granted only for genuine innovations rather than basic scientific principles or natural phenomena.
