Coverage of the worldwide database
The worldwide database enables you to search for information about published patent applications from over 80 different countries and regions.
It is based on the PCT minimum documentation
, which is defined by WIPO
as the minimum requirement for patent collections used to search for prior-art documents for the purpose of assessing novelty and inventiveness. The EPO has expanded the coverage of its internal database far beyond the PCT minimum documentation to include data from other countries and other time periods. Moreover, additional information, such as ECLA symbols and references to cited documents, is added to other fields by examiners in the course of their work.
Abstracts of non examined Japanese patent applications filed by Japanese applicants since October 1976 and all patent applications filed since 1998 which do not have a Japanese priority are available in the worldwide database since January 2005.
Due to the translation process from Japanese into English, these abstracts are not available until six months after publication.
esp@cenet® holds data on more than 60 million patents from 85 countries. A total of 30.5 million of these patents have a title, while 29.5 million have an ECLA class and 19.5 million an abstract in English.
