"(and not copyrighted, surprisingly) part of original source code"
I am truly surprised by the quoted above . How can you think the original source code is not copyrighted? As far as I know, US copyright law doesn't have distinction between different parts of software code.
Unless the upstream put the work in public domain explicitly as in the GPL FAQ link below, I don't think you understanding about copyright is any close to right.

Of course, I meant that there is no copyright notice inside the patch file. Does it mean that the distribution of any patch file, patching GPL code is illegal? Because it by itself clearly breaks
publish on each copy an appropriate copyright notice
