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.

Worth Repeating: PatentScope Graphics
This week the WIPO formally announced the newest feature in its PatentScope database: the ability to display search results in graphic format. The tool has been available in beta version for several months.
The tool converts search results into four graphic charts: 1) year of publication, 2) country of publication, 3) applicant name (first named) and 4) IPC subclass. This is the first public patent database that (to the best of my knowledge) has a search results graphical display capability.

Inventors mentioned include Frampton Ellis III (naturally contoured shoe), Daniel Davala (butter knife) and Matt Fleming (tabletop game). This month one hundred years ago, Thomas Edison received a patent on an electrical welding machine (847,746).
