CAMBIA’s Patent Lens.

Posted in General Commentary, Practice Commentary by Jake Ward on May 25, 2007

Some time back, Michael Gorman of the Tech LawForum had notified AT! about a company called CAMBIA, located in Canberra, Australia.  CAMBIA has established the “Patent Lens” project; a free, searchable patent database designed primarily for bio-tech patent searching. 

According to CAMBIA, the Patent Lens resource comprises a fully text-searchable patents database, and contains over 5,500,000 patents and patent applications from the PCT, US, and EPO databases.  Patent Lens includes the life sciences collections from these jurisdictions and has recently added all patent classifications from the US applications and granted patents.

We’ve had an opportunity to try out the Patent Lens search engine, and found it fairly useful.  The service allows keyword searching of the full text, as well as specific sections of patents and patent applications. It also provides easy access to INPADOC family and legal status data.  From a biotech and life sciences standpoint, the service now appears to include a search function for protein and DNA sequences.

Further notable features are: 1) a “predicted expiry date” function (although the function admittedly does not take into account features such as terminal disclaimers, term adjustments, etc.) that allows searching for patents that are in-force versus expired; and 2) RSS alerts for automatic updates on patent search queries.

    FYI. Neglected to add that the Tech LawForum also has a post comparing Patent Lens and the Google Patent Search function here: . Enjoy.

    Hi guys,
    Thanks for the constructive comments. The Patent Lens is expanding alot, and we’d love if your readers would keep trying it out and continuing to give us feedback.

    We have a press release coming out today that we’ve now added all Australian granted patents as full text (since 1998 – about 115,000 documents) and (in a few hours) the Australian applications (about 580,000 documents). All full text.
    And we’ve improved the interface we think. Further feedback to us is welcome. We’re here as a public-good resource.
