What is Prior Art?

  • Prior art in patent law represents any (technical) information that has been made available to the public through written or oral descriptions, through use or in any other way.
  • Even if a formerly published invention has been forgotten and only appeared once in a newspaper clipping of a local newspaper in Mongolia, it is still part of the prior art.
  • An invention is patentable only if it goes beyond prior art at the time of the patent application.
  • In addition, an invention must fulfil the conditions on inventiveness to be patentable.
