PatentPlex Claim Diff Tool

The inspiration for new Patent Bots features frequently comes from frustrations I encounter as a patent practitioner.  Recently, I was working on a child application, and I wanted to see the differences between the claims of the parent and the grandparent.  This is what I had to do:

  • Copy the claims of the grandparent into a Word doc
  • Copy the claims of the parent into a Word doc
  • Use the Word compare documents feature to see the differences

While this works, it is tedious and time consuming... To not have to do this any more, I created the PatentPlex Claim Diff Tool:


To see the differences between the claims of two patents, you just enter the patent numbers and select the claims you want to compare!  Our Claim Diff Tool is available for free for the next two weeks on our PatentPlex page.  Afterwards, you will need a PatentPlex subscription.
