If your code is really that valuable, then some one will get a programmed chip,
and remove the epoxy so they can get at the bare chip. It would then be a
reasonably simple process to erase the code protect bits and read your code.
Especially if the person(s) involved are in any way familiar with the Microchip
die layouts. Even if they were not familiar, it would not be too hard to figure
out likely places to bombard with alpha particles to clear the relevant
protection bits.

Information on how to remove the epoxy has been on this list in the past - look
for references to fuming nitric acid if I remember correctly.

If this has already been covered by others, I apologize, but have just read this
message while catching up after a holiday weekend, and busy week.
