Prior Art Search


Blue Background


What is prior art search?

An invention is eligible to receive a patent only if 

  1. It covers patentable subject matter

  2. It is novel

  3. It is not an obvious combination of pre-existing inventions

A prior art search (also called a patent search) reveals whether (or which portions of) the invention is truly novel and truly non-obvious, in light of all published literature (including patents, technical papers, products, manuals, even university theses). 

For new inventions, prior art search helps you determine how likely is it that your invention (or portions thereof) will receive a patent. For existing patents, prior art search helps you challenge their validity (for example, through an Inter Partes Review at the Patent Trial and Appellate Board).
