Patentability refers to the ability of an invention to meet the requirements for obtaining a patent. For an invention to be patentable, it must consist of patentable subject matter, be novel or consist of a novel step or improvement, be non-obvious to those versed in the art, and be useful or have utility. Patentability research will identify relevant patent references in order to determine whether the proposed invention is novel and non-obvious and therefore patentable. The research may also be used to support claims of utility. Patentability research will include a review of published patent applications and granted patents, either domestic, foreign or both, and may include a review of scientific, academic, technical, industrial, trade and business publications.
