Great! Just to clarify: A and B are employed by a Company and the
employer has all rights on code they produce. A has an assignment and
contributes code to FSF. This code is also included in a closed-source
product, distributed by the Company in binary-only form. B makes a patch
to the code and wants to propagate it into the FSF copy. B doesn't have
an assignment. IIUC, the above says this patch can't be accepted (I
understand "authorship" as personal, not corporate), even though it's
the Company who had donated code. Does this mean that, in order to have
the patch included, B (and only B, not anyone else from the Company) has
to sign a copyright assignment?

Thanks again,
