Re: Issue with Collecting Patent Data

Hi,
Thank you for your explanation. I have one more question here.
For US patents, I find there are two types of publn_nr, one is ten-digit such as "2001000344", and the other is seven-digit such as "6077663". The seven-digit matches the patent number I find from USPTO website, and I wonder what the ten-digit patent number means?
Is it the so-called "dummy publication" mentioned in the previous post as "When the EPO receives data that a certain publication/application has been cited without that publication//application being in our database, then the EPO will create a so-called 'dummy' publication"? If so, after the "dummy publication" publication gets a solid publication number from USPTO, do you consolidate the "dummy" one with the read one?
For Chinese patents, there are also two types of publn_nr, one is nine-digit such as "100334102", and the other is seven-digit such as "1665922". Does that difference have the same meaning as US patents? Thank you.
Best regards,
Wei
