Hmm, the idea seem to be patented by Microsoft, i.e. this patent from
(and other patents by Microsoft if you search for "hotpatching").
And those patent descriptions, by the way, remind the way kexec works
("A software module is hotpatched by loading a patch into memory and
modifying an instruction in the original module to jump to the patch"),
which was released much earlier... In essence, they patented kexec ;)
