Ser. corresponds to...?

[snoopy82]

Hi everyone,

I am translating a patent application, but I don't know what "Ser." means in the following sentence. Can you tell me what that word means?

This application is a continuation-in-part of each of U.S. Ser. Nos. [numbers], filed [date], Ser. No. XXXXXX, filed [date], and Ser. No. XXXXXXX, filed [date], the disclosures of which are hereby incorporated herein by reference.

Thanks in advance
