The Command Line Interface

Esp@cenet does not offer a command line interface. However, there is at least one way to modify an esp@cenet search by using qualifying terms in addition to normal search terms within the classification search fields. To accommodate all the various types of IPC-8 class codes, there are several esp@cenet field qualifiers that can be input as modifiers into the IPC classification search field. These are:

  • c: selects IPC core level
  • a: selects IPC advanced level
  • ci: selects IPC core level, invention information
  • cn: selects IPC core level, additional information
  • ai: selects IPC advanced level, invention information
  • an: selects IPC advanced level, additional information


For example, in the Advanced search form:

A search on (ci: G11B5/62) will return hits with G11B5/62 indexed as the Core IPC class.
A search for (an:G11B5/84) will return hits with G11B5/84 indexed as an Advanced Non-Invention IPC class.
