Does an invention have to be a major advance to obtain a patent?
Not necessarily. To obtain a patent for an invention, the invention must be new and inventive. An invention is new if it has not been disclosed to the public anywhere in the world before a patent application for the invention is filed. An invention is considered to be inventive if, when compared to everything else that is available to the public, it would not be obvious to a person with reasonable knowledge and experience of the subject area of the invention.
