Published Sept. 2 (WO) and Sept. 3 (EPO)

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 comprise the European 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.
