Any person who invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement may obtain a patent fulfilling the conditions and requirements of the respective country where the person wants to file the patent.

Process: The word process is defined as a process, act, or method, and primarily includes industrial or technical processes.

Machine: The term machine used in the statute needs no explanation.

Manufactured: The term manufacture refers to articles that are made, and includes all manufactured articles.

Composition: The term composition of matter relates to chemical compositions and may include mixtures of ingredients as well as new chemical compounds.

These classes of subject matter taken together include practically everything that is made by man and the processes for making the products.

A patent cannot be obtained upon a mere idea or suggestion. The patent is granted upon the new machine, manufacture, etc., as has been said, and not upon the idea or suggestion of the new machine. A complete description of the actual machine or other subject matter for which a patent is sought is required.
