Congress, apparently, has decided that false marking is only a crime on paper, and that it there should never actually be any instances where it should be enforced.
Just one of a long list of great shames in the AIA.
I, respectfully, dissent. The penalties were not proportional to any harm to consumers, at least for expired patents. Also, this law was unnecessary as there is no reason to believe that expired patent markings affect actual purchasing habits, or affect potential competitors. The qui tam craze was just the new cybersquatting, and, similarly, passed as the previous fad.
Not entirely. IIRC, we even had a post here by some manufacturer whose competitor had done just that -- falsely marked "patent pending" on a product to intimidate others from copying it. But now the manufacturer must show some form of harm before he has standing to sue, and what if there really turns out to be an application pending?
The AIA "fixed" false-marking suits by adding a standing requirement (note: I read it before final passage; it may have been changed again during reconciliation. I haven't had time to go back and check). That arguably destroys the intent of the original statute and is relatively meaningless -- now, instead of some ambulance-chaser trying to make a buck through a shakedown suit, suddenly it's competitors who will sue each other for commercial advantage.
So, now, instead of a bored attorney suing Brooks Brothers over their expired patent marking, it'll be another clothing retailer.
Instead, IMHO, Congress SHOULD have simply acknowledged that technology has changed the situation, anyone can find out when a patent expired with a few minutes of web research, and marking of an applicable patent number on a product is at worst a means of educating the public (and competitors) about the product! Even the courts could have done this.
This would limit false-marking suits to marking an inapplicable number on the product, or falsely marking "patent pending" to try to scare off competitors, both of which IMHO should still be lawsuit-worthy.
