Yes. They specifically mentioned a product. Isnt the standard whether the claims at issue are substantially the same as that during publication, if so then you have provisional rights dating from publication? I think making that determination would be very difficult, in that, you would be on the hook in a scenario wherein you stated it was ok to proceed, when it was later determined improper. Is there a good amount of case law on this?
Actually I think under § 252, the granted claims are to be "substantially identical" to those published if the patentee is to have provisional rights dating back to the publication. And I've not seen a case spending time explicating what is "substantially" identical (anyone??). In other words, I've seen little case law and in my current ignorance believe "substantally identical" means "identical except for amendments as to matters of form only".
In your own situation, then, and basing a premise on my ignorance, are there claims currently in prosecution that match (for now, say, "are identical") to the pub'd claims? (second half of question for thoughts only and no reason to answer out loud), ". . . , and which also reasonably read on a product"?). If no original independent claims remain, then past damages (from date of pub) should not be an issue.
Going forward from the (unlikely?) issue date, if there have been amendments to the independent claims, do these currently pending (and finally rejected as you mention) claims still read on your product? (don't answer aloud). Even if so, as I understand the statute, there can only be damages counting from the date of eventual grant (which obviously may never even happen). Might you now want to discuss (internally) design arounds in case these rejected claims do issue? In like situation I have also considered obtaining an independent (outside and not otherwise involved) counsel opinion regarding the validity (or in-validity) of the pending rejected claims (any including dependents that an unreasonable assignee of the letter-sending sort might think would read on my product).
PS, I've wondered what the heck is a tataboxinhibitor? Must be quite some story behind the name . . .
