Search fields (master data) - patents/utility models

The following overview lists the data fields available (master data) in the input forms of the search modes.

Please note that the number and kind of included fields have been subject to changes over the years. If your search relates to older data, you cannot rely on all relevant fields being available electronically for each IP right or each IP application.

The first column of the following table contains the respective INID code - where attributed - for the identification of bibliographic data.
An overview of all INID codes for bibliographic data relating to patents (including supplementary protection certificates, utility models and topographies) is available in the WIPO Standard ST.9.

The second column contains the actual field names of the individual search fields.

The corresponding search field code (acronym) is indicated in the third column. You need the acronyms to create a query in the Expert search mode. On the respective input form you will find many helper functions in the form of drop-down lists.

The fourth column shows the type of IP attributable to each individual field.
P = patent
Z = supplementary protection certificate
G = utility model
T = topography
Example: The field Inventor (IN) refers exclusively to patents (type of IP) while the field Applicant/owner (INH) covers all four types of IP.

The columns "Basic search", "Monitoring" and "Expert search" show whether a data field is searchable within the specific search mode. Searchable fields are identified by a plus sign, fields not searchable within a specific mode, by a minus sign.

The "Type of entry" column contains a note for the respective search field, indicating which form can be used for creating a search.

The last column contains an explanation of the individual fields. The integrated hyperlinks chosen relate to specific topics but the selection is not exhaustive.
An example for the Expert search is shown for each field, provided the field is searchable in that search mode. Detailed information on how to perform expert searches are available in the help pages section Search modes.
