Espacenet release notes (March 2016) - v.2 

1. Full-text search in the worldwide collections

Espacenet now supports full-text (FT) search in English, French and German. 

To use full-text search, you must first select the collection you wish to search in, i.e.

  • Worldwide EN - collection of published applications in English offers full-text search in English for all documents published in English which are available in full text (description and claims) from the worldwide database, or
  • Worldwide FR - collection des demandes publiées en Français offers full-text search in French for all documents published in French which are available in full text (description and claims) from the worldwide database, or
  • Worldwide DE - Sammlung veröffentlichter Anmeldungen auf Deutsch offers full-text search in German for all documents published in German which are available in full text (description and claims) from the worldwide database.

These collections include the content of the former EP and WIPO full-text databases.

1.1. Full-text search: Advanced search

Make the appropriate choice from the drop-down menu in the field Select the collection you want to search in:

Then enter at least one keyword in that language in the Enter keywords field: 

KEYWORDS 

1.2. Full-text search: Smart search

Enter keyword(s) and click Search as usual.

FREE ACCESS

Then click Refine search as indicated below:

refine search

This takes you to the Smart search screen where you can choose a full-text collection from the drop-down menu and use the following field identifiers in connection with your search terms:

ftxt = to search full text in the description and claims

desc = to search full text in the description

claims = to search full text in the claims.

The default (field identifier = txt) is for searching in the title and abstract as well as in the applicant and inventor fields.

2. Search using combination sets of classifications

Combination sets ("C-sets", "Combi sets") are ordered lists of linked CPC symbols created by patent examiners. Combination sets classify technical features in context or "taken in combination". The scope of a combination set can vary across technical fields.

These classification combination sets are now searchable in Espacenet. Please note you can only search for combination sets in Smart search and to do so you must use the field identifier "cpcc".

You can enter up to ten classification symbols in the search field each separated by a space and the system will use a default Boolean AND operator.

Example:

free access 2

This example retrieves patent documents that have been assigned combination sets that include C08F8/30 and C08F287/02.

You can also refine your search by using the Boolean operators AND or OR along with proximity operators.

Examples: 

  • Boolean: cpcc=C08F8/30 OR cpcc=C08F297/02
  • Boolean: cpcc=C08F8/30 AND cpcc=C08F297/02
  • Proximity: cpcc=C08F8/30 prox/distance<3 cpcc=C08F297/02

For further information on the use of Boolean and proximity operators, please refer to Help in Espacenet.

The combination sets are also visible in the Bibliographic data panel under C-sets.

These appear once you click more (if applicable) in the cooperative field:
