No. The only case where you can lose "IP" (a deliberately misleading term that lumps together several completely unrelated legal constructs, none of which are property) is in the case of a trademark being diluted to the point that no reasonable person can be expected to know it's a trademark. Things like heroin, trampoline, escalator, dumpster, dry ice, etc. That's it. Copyrights and patents, which are different things from trademarks, aren't lost until they expire.
