BioWorld has replaced its publication of European patent disclosures with a free, more extensive and more timely patent index on the home page of its online site, www.bioworld.com.

The offering, made in collaboration with affiliate company Derwent Information, provides patent extracts from the Derwent World Patents Index database on filings made with European, U.S., Japanese, World and Great Britain patent authorities. The information is sorted by month of publication, and now includes records back through June.

All BioWorld subscribers have free access to the data. However, subscribers who have not registered on the online site must do so before accessing information for the first time. Registration afterward is not required.

Each patent listing includes a summary, the issuing authority, the patent number, publication date and an accession number, which can be used to access the Derwent records for detailed data on an individual filing.
