Caveats
To keep an eye on the progress of someone else's 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 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published, or withdrawn, refused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registered, or withdrawn, refused or abandoned after publication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

- patent surrendered
or revoked
- assignment
application received
- patent assigned,
either partially or in full
- anything else
