Patent Lens Adds Predicted Expiry Date for US Patents

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.
