Published Nov. 11 & 19 (EPO) & Nov. 12 (WO)
BioWorldLs weekly European patent preview lists inalphabetical order by assignee, and briefly summarizes, allsalient biotechnology patent applications as they are madepublic in Europe.
European patent offices publish full texts of patent applicationsworldwide within six months of their filing, and months toyears before the corresponding U.S. patent issues.
Two organizations and Great Britain (GB) comprise theEuropean system:
-- The European Patent Office (EPO) covers the dozen membercountries of the European Economic Community.
-- The World Intellectual Property Organization (WO) serves alarger number of countries around the world.
As a reader service, BioWorld will supply full texts of Europeanpatent disclosures upon request. (These can run anywherefrom half a dozen to 100 pages.) A flat fee of $55 each, payablein advance by credit card, defrays airmail postage and handlingcosts from Europe. Allow 10 days to two weeks for delivery.
To order, call 1-800-879-8790. Cite the date the disclosureappeared in BioWorld, the assignee and the serial number.
