Patent Lens, a public patent database containing more than 6 million US, EP and WO patent documents, now allows searchers to limit searches by the predicted expiry date for granted US patents. The date is displayed in the body of the record.
Searchers should note that the predicted expiry date is calculated and does not take into account terminal disclaimers, term extensions or adjustments.
Patent Lens is operated as a "public good global resource for increasing patent transparency" by Cambia, an independent, non-profit scientific research institute located in Canberra Australia.
About Me
- Michael White
- I'm the librarian for research services in the Engineering and Science Library at Queen's University in Kingston, Ontario. I've been working with patent information since 1991, including seven years at the U.S. Patent and Trademark Office. I believe that the dissemination of patent information is a public good and should be promoted, especially in the education of science and engineering students.
