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.  Searching Espacenet is a good option.  Doing a regular Google search with the title or patent number is another good way to search.

 

  • 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.
