Um, well, yeah, I guess copying a spellbook without permission is clearly
1. Copyright infringement
2. Breach of confidence - theft of trade secrets
3. If it's a 'name' spell like Tenser's Floating Disk, TM infringement
4. Or if not #2, possibly infringing a patented spell
5. And I expect there could be registered design right in a spell's aesthetic elements
6. If you strip the name out to avoid #3, infringement of the spell author's moral right of paternity
7. And there may be a sui generis spell protection right.
Why summon demons to get your spell book back, when you can sumon lawyers?
1/ What copyright? Copyright is
created by the current laws of our world. It's not something that exists in all ages across history. It's not something
ever mentioned in the laws of any D&D world I've ever seen.
2/ Only if the spell were researched and never shared with anyone. Without a license, any sharing = full disclosure.
3/ Trademark is something our laws
created. See point (1).
4/ Patents, like copyrights and trademarks, don't exist unless laws create them. See point (1).
5/ "Look & feel" issues? See point (1).
6/ Moral right? I don't see any notes in copying a spell about the act
ever being [Evil], and since D&D has concrete, absolute morality, I don't see a whole lot of wiggle room here.
7/ Again, see point (1).
D&D World has no inherent legal context, so while these issues may exist in some worlds, they would require a significant change in some default assumptions.

However, peeking into someone's spellbook uninvited is most certainly
rude, and that's more than sufficient reason for that someone to kill you.
