[Page] 205 [My Comments] And this is the only Patry’s proposal with which I wholeheartedly agree. There are indeed millions of works that their owners don’t care to protect or capitalize on. If the creators expect the courts to enforce their rights against all kinds of unauthorized uses, it is only fair to ensure that the creators value these rights sufficiently to demonstrate interest in their protection not only when they managed to catch some deep pockets using their works without permission. This is especially true if the potential term of protection will be perpetual. [Quote from Patry’s book] 
The way to resolve this problem is through mandatory use of formalities that require copyright owners to take steps to affirm their continued desire to claim their rights, principally the requirement that the copyright owner file a document with a government agency expressing a continued interest in the work.
