I am trying to conduct a specific search on WIPO. The User's Guide is not helping me at all. I would like to search EP patents from December 1, 2017 to January 31, 2018 for any patents issued to Waters Corporation. I only want issued patents. Can someone help me with the search string?

Thank you,

Jerry O'Connor-Fix

  1. Jerry, I just tried it and believe this is what you're looking for:

    1. Go to https://patentscope.wipo.int/search/en/structuredSearch.jsf
    2. Under Publication Date, copy [12.01.2017 TO 01.18.2018] into the text box field to the right of that option
    3. Under Applicant, copy Waters Corporation into the text box field to the right of that option
    4. Under Office Code, copy EP into the text box field to the right of that option

    It returned 7 results.  In the first list, a couple of the listed publication dates were before/after the period, but if you look at the "documents" tab for them, you'll see they have another published version.  I did this quickly but did not see a way to limit to grants only.  That might be possible with a different code, but the list was small enough that I thought you'd want to know this method asap.


  2. Hi Jerry

    There are some issues with your question to start with but Matthew is mostly right with the general approach. There are a couple of things that should be done instead, and this may be to guide Matthew as much as you.  Firstly, the date string should conform to 'the rest of the world' and be in dd.mm.yyyy format, so [01.12.2017 TO 18.01.2018].  Secondly I would use Waters Corp* or perhaps even just Waters in the applicant field.  I'm not sure how familiar you are with searching but the asterisk allows you to pick up Corp as well as Corporation.

    In terms of your question, I doubt PatentScope will provide the answers, so I tried Espacenet https://worldwide.espacenet.com/advancedSearch?locale=en_EP but for some reason it won't pick up granted applications by publication date, but really should be able to do the job.

    There's also some issue with who you're searching for.  Is it just Waters Corp or is it Waters Technologies Corp or who, because there are a few names coming up.

    I needed to use something a little more powerful to get you some answers seeing as I'm having trouble showing you how.  Look at









    These are the applications fitting your criteria above.



  3. Not sure why you would go to PATENTSCOPE for EP patents.  Espacenet is the obvious choice https://worldwide.espacenet.com 

    The way to find granted EPs is to enter EPB in the publication number field. This generally works for other B kind code documents from other authorities.

  4. Hi Jerry,

    the problem here is that with Espacenet and Patentscope the publication date is searched ONLY as the publication date of the application and not as the publication date of the issued patent. Selecting the date range must consider this.

    Compared to the prior suggestions I would recommend to changing the date range in Patentscope to [20170101 TO 20180131]. This will result in a list of 20 documents with #19 as the only one granted (EP3118503B, publication date 20170118, issue date 20171227). In this case the examination period was quite short, so the granted patent was issued within one year. In other cases the date range should be increased step by step.

    Using Espacenet the date range should be 201701:201801. As Nigel pointed out you can restrict the result list to issued patents by asking for EPB, using Smart search enter PN=EPB. The result list will include only the one granted patent (EP3118503B, publication date 20170118, issue date 20171227).

    Concerning the applicant's name I would recommend to try only the main part of the company name, Waters alone works for this firm. In case of too many results I would add a further part of the main name, here tech*. Generally I avoid to use the legal form of a company because this is often omitted and also often changed.

    Hopefully this was helpful.

  5. Hi Jerry,

    there is a further free Patent database offered by the German Patent and Trademark Office DPMA. This one called DEPATISnet allows for quite sophisticated searches. And this database searches for publication dates of applications and issued patents. There is an English user interface available.

    To get the list Frazer published you could use the DEPATISnet expert search https://depatisnet.dpma.de/DepatisNet/depatisnet?action=experte
    and enter:
    PUB>=01.12.2017 and PUB<=31.01.2018 and PA=waters and PC=EP and PCOD=B#

    PUB=publication date
    PC=publication country
    PCOD=publication code / kind code, B#=publication code B for granted EP-Patents with # standing for an additional character (mostly 1, but can also be 2, 3, 8, 9)

    But be aware, that not all patent offices use or used B as kind code for granted patents. WIPO published an INVENTORY OF KINDS OF PATENT DOCUMENTS LISTED ACCORDING TO THE ISSUING INDUSTRIAL PROPERTY OFFICE, that can be found here: http://www.wipo.int/export/sites/www/standards/en/pdf/07-03-02.pdf
