What are the main sections of the International Preliminary Examination Report (IPER)?

The International Preliminary Examination Report (IPER) consists of several main sections as outlined in MPEP 1879:

  • Cover sheet (Form PCT/IPEA/409): Contains bibliographic data and classifications.
  • Basis of the report: Indicates which documents form the basis for the examination.
  • Box No. I: States whether the report has been established.
  • Box No. II: Contains any observations on the application’s priority.
  • Box No. III: Addresses non-establishment of opinion for certain claims.
  • Box No. IV: Addresses lack of unity of invention.
  • Box No. V: Contains the reasoned statement with regard to novelty, inventive step, and industrial applicability.
  • Box No. VI: Lists certain documents cited.
  • Box No. VII: Contains certain defects in the international application.
  • Box No. VIII: Contains certain observations on the international application.

The MPEP states: “The examiner must complete the first sheet of the PCT/IPEA/409 by filling in boxes I to VIII. The examiner must indicate in Box No. I whether or not the report was established on the basis of the international application in the language in which it was filed.”
