I agree; problem is, as you say, the legislation is decades old and has not been brought up-to-date to mirror the world today.
In my day (early 70's) most of the Apple "look and feel" type patents would not have been given Patent protection. Maybe they could have been a registered design but I feel they are too broad even for that.
As I've said before, the Patent Offices of the world simply don't have the resources to keep up any more.
