2. An international application was filed on 4 July 2025 without claiming priority. The description refers to drawings, but none are included. The drawings are submitted on 20 July 2025. Which statement(s) is/are correct? (multiple choice)
❌ A. The international filing date remains 4 July 2025.
✅ B. The international filing date will become 20 July 2025.
❌ C. The international filing date can remain 4 July 2025 if the applicant adds a declaration to priority to an earlier application which contained the same drawings, at the latest when the missing drawings are filed.
❌ D. It is not possible to file the drawings later, so they will be disregarded.
✅ E. In case the receiving Office does not notice the missing drawings, the latest day to file them is 4 September 2025.
Answer: Filing missing drawings is possible under Rule 20.5(a) PCT. The filing date will change to the date when the rO receives the missing part under Rule 20.5(c) PCT. Incorporation by reference under R.20.6 PCT is not possible as priority was not claimed on the date of filing. Time limit is indeed 2 months from 4 July 2025, legal basis: Rule 20.7(a)(ii) PCT.
