KR – Korean Publication and Application Numbers

When importing Korean documents into the PatentSight, 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, 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:

Make sure that your list only contains application numbers
Add one application number of an entirely different format (e.g., the PCT application number WO1978US00001) to your list, so that PatentSight will recognize that you are importing application numbers.
During the import process, uncheck the additional application number (e.g., WO1978US00001) so that it will not be added to your tag.

Since the application number of one Korean document can also exist in 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.
