MPEP Chapter 1800 (Patent Cooperation Treaty) consistently generates 8–10 questions per Patent Bar Exam. First, know who can file in the U.S. Receiving Office (RO/US): at least one applicant must be a U.S. resident or U.S. national (MPEP § 1805); if no applicant is a U.S. resident or national, the application is forwarded to the International Bureau (RO/IB) in Geneva.
Second, distinguish PCT Article 19 amendments (claims only, filed directly with the International Bureau within 2 months of transmittal of the ISR or 16 months from the priority date, whichever is later, under MPEP § 1853) from PCT Article 34 amendments (claims, description, and drawings, filed with the International Preliminary Examining Authority under Chapter II prior to establishment of the IPRP).
Third, know U.S. National Stage entry under 35 U.S.C. 371 (MPEP § 1893): the 30-month deadline from the priority date, what is required to obtain a National Stage receipt date (basic national fee + copy of the international application unless previously communicated by IB), and the difference between a 35 U.S.C. 371 national stage entry and a 35 U.S.C. 111(a) bypass continuation.
Under PCT Rule 42.1 and MPEP § 1842(VII), the time limit for establishing the International Search Report is 3 months from the receipt of the search copy by the International Searching Authority or 9 months from the priority date, whichever time limit expires later.
PCT Article 19 allows amendments to the claims only (filed with the IB after receiving the ISR), whereas PCT Article 34 allows amendments to the claims, description, and drawings during Chapter II International Preliminary Examination before the IPEA.
Under MPEP § 1893.03(d) and § 823, a 35 U.S.C. 371 national stage application is examined under the PCT "Unity of Invention" standard (PCT Rule 13 and 37 CFR 1.475), whereas a 35 U.S.C. 111(a) bypass continuation is examined under the U.S. " independent and distinct" restriction standard (35 U.S.C. 121).
