WIPO has announced that due to privacy concerns it will remove address data for inventors and individual applicants from its PatentScope database. The data will not be indexed or displayed in Internet search engines. This will not affect PatentScope searches or RSS search alerts. I ran several test searches based on city names and postal codes and retrieved the expected documents, although address data did not appear in individual records. However, address data will still appear on the frontpage of PCT documents in PDF format.
It is unclear if this policy will apply to WIPO data obtained by third-party database producers such as FreePatentsOnline and Patent Lens. As of December 30, inventor address data from PCT documents was still indexed and displayed in Patent Lens.
