Title is not original and worse, may be false. I need some more expert clarification here but two possible issues: Prior art rules for publication are relevant re patentablity, but invalidation is a different matter than patent granting. IANAL but I believe any proof of priority before the claimed date of invention (?) can obviate a patent (which is different than the rules for granting a patent.) Nor are courts the only place patents are invalidated. Also, in the past "publication" could mean public display. One doesn't want to end up in the position where a technique millions use already, is patentable.
