does msft license this from sybase.

I don't know the full history of that relationship. As I recall (and I can't find news stories to confirm my recollection), Microsoft and Sybase had some kind of co-development deal for the first few versions of SQL Server and both sold products with that name which shared enough commonality that many third-party add-ons worked with either system. (I found several pages from '96 or so which tout such products.) Sybase doesn't use the "SQL Server" name anymore. "Adaptive Server" seems to be the current product name.

I believe Microsoft went its own way eventually (as they usually do).
This page shows that MS now tries to get db admins to switch away from Sybase products:
microsoft.com

SQL, itself, is an open standard, developed originally by E.F. Codd at IBM. Since it's open, no royalties need be paid to use it, but the database engines themselves are proprietary. It's possible Microsoft and Sybase still share some common code. My preview copy of MSSQL 6 has expired or I'd check the Help:About dialog. If there's still a relationship of any kind, one would see a copyright notice there. Perhaps someone with a copy of it could look.
