Advanced searching chemical structures in patents

May 2011 Author: ()

Patents allow you a limited monopoly on your invention. Equally important, they allow your competitors the same monopoly on their inventions. Chemical structures in patents are frequently described in broad terms called Markush structures. This talk will describe some of the typical Markush structure searches of chemical patents, which are used to determine

  • structures that are covered by many patents versus the “white space”;
  • drug candidates structures that are not in the scope of the patented Markushes but are likely to have the same properties;
  • whether an invention is patentable;
  • whether you might have freedom to operate; or
  • whether a third party’s patents are valid or can be “busted”.
