Introduction to Patent Searching

Searching the patent literature can help you to learn about other engineers' novel approaches to solving design and analysis problems similar to your own. A thorough patent search can also help you to determine if your solution can be patented!

Patent Searching Tutorial

Patent Searching

  • Patent searching is complex and time consuming.  Plan on spending a few hours learning the search process and additional hours searching and evaluating results.

  • You will need to document your search.  Keep careful records of what databases you search, what terms and classification numbers you search in the databases, document numbers of the patent and application documents that you retrieve and examine, and the date and time of your search.

  • Keyword searching alone is never enough.  A comprehensive patent search requires that you search by classification and sub-classification numbers.
