Not entirely - public domain as a result of failure to defend a copyright was overturned in 2014 when the Supreme Court issued its opinion in Petrella v. Metro-Goldwyn-Mayer, Inc.
However, in that judgement, blatant failure does lead to the IP passing into PD.
The belief however persists in most owners of IP, that they MUST protect at all costs!

True for TMs, of course!
