	I am not going to pay an attorney $200 so that I can write
a netnews article, and I doubt that you would either.  Do you remeber
where you heard about this principle?  Please post your answer to the
net as that I think such a reference will be useful to many
gnu.misc.discuss readers.

	My only recollection of such a principle had to do with some
discussion either on the net or in person (I don't remember which)
about Unisys's letter to _Dr. Dobbs Journal_ about their patent on
LZW data compression.

	I suspect that there exists some "sleeping on one's rights"
principle for copyrights, but I'd like to know the details.  For
example, I'd like to know how this principle allegedly prevents
Apple from suing other competing GUI developers after the Microsoft
lawsuit, but did not prevent Lotus from waiting until after the
Paperback lawsuit to sue Borland.
