Strategies for Searching Patents

When you are ready to explore the patent literature

What you already know and your motivation for searching the patent literature will guide your work:

  • By number.  With a patent number or patent application number, finding the document should be not too hard.  It should be just a matter of finding a database with the right content and matching the required format.  Espacenet is a good choice.  Doing a regular Google search with the title or patent number can also be successful.
  • Keyword searching is appropriate for exploratory work that can be less than comprehensive or as a strategic approach to classification searching.  Google Patents is a good place to do that. 
  • Classification searching is the formal approach to subject searching recommended by patent examiners.  Espacenet - Classification Search and the U.S. Patent and Trademark Office Seven Step Strategy both offer guidance on this approach.  Also, Google Patents: Advanced Search and Google Patents link to classification information.
