Second Sheet of the International Search Report, Box B

The following sections are under Box B (Fields Searched) of the second sheet of the International Search Report (ISR).

Minimum documentation searched

Refer to 6.1.2.4 Extent of Search and paragraph 16.54 of the PCT International Search and Preliminary Examination Guidelines.

If International Patent Classification (IPC) marks were searched without using keywords to restrict the search, enter the marks searched. DO NOT use ‘IPC: AS ABOVE’.

If keywords were used in conjunction with IPC marks to restrict the search, then leave this section blank.

Documentation searched other than minimum documentation

This section is used for non-electronic databases searched, for example, paper or microfilm. PCT third party observations may also be entered here – see 6.3.5.3 PCT Third Party Observations.

Electronic database consulted

Always include

  • The names of any electronic databases consulted

  • Any broad (Subclass Level or lower) IPC marks (if used for searching)

  • Keywords (search terms), if they are used  

Keywords

If a large number of keywords is used, then a representative sample of the keywords could be used. For example, ‘Keywords:  A, B, C, and similar terms’. Truncation symbols need not be included. The logic used in relation to the search terms should not be included.

Partial structure searches

Partial structure searches are not conveniently indicated on the search report. If a partial structure search was carried out, this can be conveyed using a statement such as ‘partial structure search carried out based on the quinoline nucleus in formula (I)’.

Sequences searches

Sequence searches should be dealt with in the same way as partial structure searches. An example statement is ‘search of SEQ ID 1-5’.

Examples – electronic database consulted section

The following is a non-exhaustive list of examples of formats in which electronic databases consulted information may be presented in an ISR.

Single databases

  • JAPIO & keywords: A, B, C, and similar terms

  • MEDLINE & keywords: A, B, C, and similar terms

  • CA: Structure searched based on Formula (I)

  • Espacenet keywords: A, B, C

Multiple databases

  • DWPI & keywords: A, B, C, and similar terms
    (note that DWPI includes WPAT, WPI, WPIL)

  • DWPI IPC A01B 1/- & keywords: A, B, C

  • CA & WPIDS: IPC C07D 409/- & keywords: A, B, C

  • EPODOC, WPIAP, Google Patents, Google, Google Images, Espacenet, TXTE

  • IPC/CPC: A61M 16/20, A62B 9/02, A62B 18/10, A61F 5/56
    Keywords: A, B, C, D, E, or the like, Applicant Name​​​​​​​

Applicant/Inventor search

If an applicant/inventor search was carried out, it should be indicated in this box. This could be done as a generic statement and does not need to be as detailed as in the Search Information Statement. For example, ‘<database>: Applicant/Inventor name search’, inserting the databases used.

Note:

  • It is not acceptable to merely put ‘keywords searched’ without specifying the actual keywords used.

  • There is no need to indicate the way the database was accessed. For example, there is no need to specify that Espacenet was accessed via the Internet, or MEDLINE via STN.
