Searching Tips

To be most effective in your search for patents you must determine how your invention works, NOT how you will use your invention.

  • Start by making a list of words that describe your idea (including synonyms)
  • Record class/subclass of any related terms
  • Ask yourself:
    • What does the invention do?
    • What is the end result/anything unique/special/ unexpected? 
    • What is it made of/method or material of fabrication? 
    • What is it used for? (think verbs, as well as nouns)
  • Keep track of useful and non-useful patents (by patent number) to avoid duplication of efforts
