The esp@cenet network
http://ep.espacenet.com/
esp@cenet is a free service on the internet provided by the European
Patent Organisation through the EPO and the national offices of its members
states. It is possible to search all the patent applications published
in the past two years (or more in some cases) by any national office in
the European Patent Organisation. esp@cenet can also be used to find
English-language abstracts of documents in the European Patent Office's
in-house databases of patents from throughout the world. A
large proportion of the data goes back to 1970. Following an online
search, esp@cenet displays the bibliographic data and an English-language
abstract for each document. If a patent document was published in several
countries, then one representatieve document has been selected for inclusion
in the esp@cenet data. If they are
available, drawings and the full text of the documents are provided online.
In addition, images of the paper publications are available back to 1920
for the most important countries.
