The simple answer is "no."
Only the United States has interferences, and one or more of the patent
applications involved has to be a pending application. Anything that happens
during prosecution of a pending patent application is kept secret by the USPTO,
so no announcements of ongoing interferences are made.
On rare occasions, the owner of an issued patent involved in an interference may
make the information public. When the interference is settled and claims are
cancelled in an issued patent, the information is published in the Official
Gazette, but there's no announcement if the issued patent prevails.

Subject: Interferences
Is there anyway of finding out if a patent is in interference?
Thanks
