SciFinder-n: key features

if you are interested in finding chemistry-related patents, these are the advantages of using SciFinder:

  • It indexes substance names, molecular formulas and registry numbers
  • You can search by structure, substructure or reaction, not just text
  • The PatentPak feature provides easy access to substances in patents

But you cannot search by patent classification code.


PatentPak is a feature of SciFinder-n which presents information from 46 of the patent authorities in a format which is designed to provide quicker and easier access.  For example it extracts chemical structures and links directly to the patent PDF.  For more information there is a video from CAS.
