Indeed. The lack of copyright notices prior to Berne was also a big problem
for enforcing copyright claims, which is why most companies relied on trade
secrets prior to the mid 80s. It's a big reason, I think, the settlement
punted on trade secret protections, but made a big deal about respecting
each other's copyrights (despite preliminary rulings casting doubt in that
area).
