Currently US, EP, WO, and CA patent documents are handled. A future update will also handle documents from other jurisdictions such as DE. - FreePatentsOnline - Espacenet We do our best to present the claims trees and information correctly, but we cannot guarantee results because the supported websites are dynamic and often changing. The extension is provided ‘As-Is’ without any express or implied warranty of any kind.
