The front page of Annex 1

The front page may reveal interesting information:
  • the proprietor: is there another annex of the same proprietor, be extra alert for 'first application' issues
  • priority country: WTO state and Annex 1 is a Euro-PCT, check the transitional provisions
  • priority claimed from a US continuation: invalid, it can never be the first application;
    from a US continuation in part - only valid for the later added matter
  • warning that claims have been added after filing (it must thus be under EPC2000): all claims must be examined also for added subject-matter
  • a B1 publication: if the client indicates that a central limitation has taken place (and what) be aware that you must attack the limited claims and not the claims of the B1 publication
