  1. Full list of IPE Patent Search Toolbar's content is now available here:

    1. Hi Mikk, hope my photo doesn`t scare you! There is an interesting product called PatOffice which I have used and is very good for in house database development, full text searching and autmoated ranked updates. Have you tried it?

      1. Hi Edward!

        Thank you for the PatOffice link! This is something new, never seen it it free tool? Or do you have also link where we can find more information about it?

        1. Hi Kristin and Mikk,

          Patoffice solves alot of problems for the in house manager, searcher and attorney. Basically you can upload all the numbers of a patent search, Patoffice will retrieve the xml and then you can full text search, rank and notate. You can then set parameters for automated ranking on a weekly or monthly basis, you also distribute documents to team members and mark them as reviewed or not.

          So you can build your own database.

          The guys at Patoffice Guenther Gottshalk and Lino Gartzen are all very friendly and always interested to hear from search professionals, and

          It has been updated recently but I am not aware of these updates as I am now working on some products myself. May ask some of you for opinions or collaborations, patent pending!


  2. Hi Eddie,

    I hope you're doing well!  Thanks for posting about the PatOffice product - I created a wiki page for this product over on Intellogist..

    But I can't find much information about the product at the link you posted.  Would you like to explain a little bit more about what the product does?  If so, I can capture it on the wiki so that the community can learn more about it- or you can edit the wiki page yourself (after registering on Intellogist). 

    Has anyone else had any experience with this system that they'd like to share?


    1. Kristin,

      Thats good to know, I`ll tell the lads at Patoffice to get some content together.


  3. Hi Eddie,

    It would be also nice to create English language interface as well, not all of us can understand German. Another quick observation: Sitemap link on the website dosn't work even in German interface.


    1. Sorry Yuri, maybe this is the better url

      I have informed Guenther and Lino that this is being discussed, so I hope to get them involved. They own it after all! But thanks for your comment and interest. I wish I had PatOffice in my last job.


  4. Hi Friends,

    All bibliographic and abstracts with full citation and legal status information of Japanese unexamined patents dating back to 1989 would be made available in English language without no time lag in publication date. Please refer to World Patent Information 31 (2009) 131-134. The name of this database is JP-NETe.


  5. I just wanted to add that for anyone who is interested in learning more about JP-NETe, Intellogist has published a free report at
