Prior Art

What is "Prior Art"?

Prior art is considered by the Patent and Trademark Office (PTO) in determining patentability, and by courts in patent litigation concerning the validity of the patent. Examples of "prior art" include any of the following items:

  • any product that was publicly known or used by others in the United States before the patented invention was made;
  • other patents that issued more than one year before the filing date of the patent, or before the invention was made;
  • publications having a date more than one year before the filing date of the patent, or before the invention was made;
  • any product that was in public use or on sale in the United States more than one year before the patent was filed; and
  • any product that was made by anyone before the named inventors created the patented product where the product was not abandoned, suppressed, or concealed.
