Often when you are searching for patents you are trying to determine if anyone else has invented your product or to determine what else has been done. Most likely you are doing a keyword search. Keyword searching can provide a lot of false hits. To think of keywords think of:

  • What is the function? Is it a product or process?
  • How will the invention be used?
  • What is the stucture of the invention?

Typically it is best to avoid terms such as device as well as trademarks or product names (because these are often not included in the patent application).
