3. 11. Lack of unity during the PCT Chapter II procedure

If an invitation to pay additional fees was issued during Chapter I and the applicant paid some or all of the required additional fees, and if, where applicable, the objection as to lack of unity was at least partly upheld during a protest procedure, then under Chapter II the applicant will normally be invited (using Form 405) to pay additional preliminary examination fees if all the searched inventions are also to be examined under Chapter II. Inventions for which no search fees were paid cannot be pursued and will thus also not be objected to or commented on. See GL/PCT‑EPO C‑V.
