I recently added four new RSS feeds.  You will now be able to view the 20 most recent posts for each of the Federal Register, General, Patent, and Trademark notices from the USPTO website.  I am not aware of any other site or tool which offers these feeds.  Rethink(IP) had similar RSS feeds but they haven't been updated for a number of months.  Thus, to my knowledge, this is an exclusive feature of the Patent Pal.

In adding these RSS feeds, I deleted the fedcirc.us feeds and the Patents tracked by gov feeds since there has been little activity on those for a few months.   If there is a lot of interest from users in restoring those feeds I will do so.
