As you see in sibling replies, in many industries where a given hand writable concept has intellectual property value readily assessed in the millions to billions, and/or the deliverable itself may be in written or sketch form, it's quite often true that: (a) employees aren't allowed to have/use their own paper notebooks in the first place (b) if they do, then, yes, the notebooks don't leave unless Security reviews (if removal is even allowed) However, any number of such traditional approaches stop working when remote work is a thing. Technologies are needed if a firm wishes to retain the same level of awareness of what's happening to its IP while allowing employee flexibility (which, hopefully, firms are learning they should strive to allow).
