3. Searched claims did not comply with unity of invention
If, at the search stage, an objection of lack of unity was raised but exceptionally it was chosen not to request the applicant to pay additional search fees, the examination is carried out on the entire application. No invitation to pay additional fees (Form 405) is sent; instead, the WO-IPEA/IPER is established for all searched inventions. Under Section IV, it is indicated that the requirement of unity is not fulfilled.
