      Importing Data into PatentSight

      Overview of Import Functions

      Users can import their own lists of patent numbers and internal information regarding these numbers into the PatentSight BI. The sets of patents imported and the information mapped to them can be used in various analyses. To import your patent data, you can choose from the three import options below:

      • Quick import search results
        "Quick import search results" is a convenient option to directly apply a list of patent numbers to the PatentSight search filter. Your tag will be automatically created and saved in a folder called "Quick imports" which can be found in your user folder. Once imported, you can always rename the tag or save it in a different folder.
        NOTE: The option "Quick import search results" does not allow you to review and/or edit mismatched patent numbers during the import process. We therefore only recommend this option if you are working with a list of patent numbers that is importable into the PatentSight BI. If you want to make sure if and how a list of patent numbers imported has been matched, we recommend using one of the other import options. 
      • Import patents to Tag
        The option "Import patents to Tag" allows you to review numbers that could not be matched or have resulted in ambiguous matches. In many cases, the numbers can be matched correctly in the import dialogue by changing the format according to the PatentSight guidelines as outlined below. Moreover, you can export an overview of the matching results via the import dialogue.
        Note that the option "Import patents to Tag" does not create a tag fully automatically.  In the final step of the import process, you will have to name your tag and save it in a folder of your choice. Click HERE for more details on Tags and Tagging.
      • Import data to Custom Fields
        Similarly to Tags, Custom Fields also allow you to import sets of patents of your choice. In contrast to tags, Custom Fields can be used not only as filter elements and groupings in charts and tables – they can also be used as measures, e.g. on chart axes. Click HERE for more details on Custom Fields.

       

      Important Points to Keep in Mind  

      • The list of patent numbers to be imported
        In general we recommend importing only publication numbers (or registration numbers). If your list contains both application and publication numbers, there is an increased risk of mismatches. Therefore, we highly recommend importing either a list with application numbers only or a list with publication numbers only.

      • Recently filed patents
        Please note that patents that have been only recently filed or published at a local patent office might not yet be available in the PatentSight database. 

      • Other IP rights
        Please note that if you import other IP rights, such as utility models or design patents, even if these documents are matched correctly, they might not be available for analysis. 

      • Difference between the number of patent documents imported and the import results in PatentSight
        There may be a difference between the number of patent documents (rows) you have imported and the number of patent families your documents have been matched to. This can happed for the following reasons:
        • If you import a list of patent documents, in most cases, several documents will be matched to and aggregated into one patent family (Simple Patent Family) in the PatentSight BI. 
        • If your list contains inactive patents and utility models, these rights will not be automatically included in your analysis per default. If you want to include these rights, turn on "Incl. inactive" and/or "Incl. other IP rights" at the top of the search filter.

       

       

      CN – Chinese Publication and Application Numbers

      In general, Chinese publication numbers (公开号; 授权公告号) can be imported in the same format as they are stated in the original patent specifications. 

      To import Chinese patent numbers (专利号),  "ZL" needs to be replaced by "CN". If the kind code is ".X", this kind code needs to be deleted.

      When importing Chinese application numbers (申请号), the country code "CN" needs to be added. If the kind code is ".X", this kind code needs to be deleted.

      DE – German Publication and Application Numbers

      German application numbers can also be imported in the same format as they are stated in the original patent specifications. However, here too, we recommend deleting all spaces.

      Note: 
      Please make sure to import either a list of only publication numbers or a list of only application numbers! Mixing different kinds of numbers can result in mismatches.

      JP – Japanese Publication and Application Numbers


      If converting into Latin transcription, in general, Japanese patent numbers can be imported using the following number format:

      country code　＋　serial number　＋　kind code

      Here, "serial number " refers to either the publication number or the application number. However, we recommend importing publication numbers. If you also want to import application numbers, we recommend making two separate lists (one with publication numbers and one with application numbers) and importing them separately.

      Note: Depending on the publication or application number, several different documents may be matched (ambiguous match). To obtain more accurate matching results, we therefore recommend adding the kind code of the document  following its serial number.

      KR – Korean Publication and Application Numbers

      When importing Korean documents into the PatentSight BI, we highly recommend using a list of publication numbers.  It is necessary to add the country code "KR" and the kind code "A". Moreover, the serial number must consist of 7 digits.

      To import Korean registration numbers, it is necessary to add the country code "KR" and the kind code "B1". Moreover, just like for publication numbers, the serial number must consist of 7 digits.

      Although it is possible to import Korean application numbers into the PatentSight BI, we strongly recommend importing publication numbers instead. Since the application number of one Korean document can also exist as publication number of a different Korean document,  PatentSight might interpret a list of application numbers as publication numbers. If you only have a list of Korean application numbers, we recommend the following workaround.

      Workaround to import Korean application numbers:

      1. Make sure that your list only contains application numbers 
      2. Add one application number of a different format (e.g. the PCT application number WO1978US00001) to your list, so that our system will recognize that you are importing application numbers (and not publication numbers).
      3. During the import process, uncheck the additional application number (WO1978US00001), so that it will not be added to your tag (see picture below).

      Since the application number of one Korean document can also exist in exactly the same format as the publication number of a different Korean document, we highly recommend importing publication numbers instead of application numbers.  When importing application numbers, please use a list that only contains application numbers and double-check your matching results.

        US – US Publication and Application Numbers

        In general, US publication numbers can be imported in the same format as they are stated in the original patent specifications:

        USyyyy123456(7)(A1)

        country code (US)　+　year (4 digits)　+　serial number (6-7 digits)　(+　kind code)

         

        US patent numbers can also be imported in the same format as they are stated in the original patent specifications:

        US1234567(Bn)

        country code (US)　+　serial number (1-7 digits)　(+　kind code)
         

        US application numbers can be also imported into the PatentSight BI – however, we strongly recommend importing publication numbers instead. In order to import US application numbers, the year (4 digits) must be added and, in some cases, the series code (≠ serial number) needs to be deleted.
