Caveats

To keep an eye on the progress of someone else's patent application or patent, you can register a caveat with us.

A caveat is a warning, or notification, that some action has taken place on a patent application or patent. We do not tell the applicant or patent owner of the patent that a caveat is in place.

You can ask us to notify you of any of the following events or actions:

  • application published, or withdrawn, refused or deemed abandoned before publication
  • opposition filed against an application
  • application registered, or withdrawn, refused or abandoned after publication
  • patent not renewed
  • patent renewed or expired
  • patent surrendered or revoked
  • assignment application received
  • patent assigned, either partially or in full
  • anything else
