            <div>Client has what it believes to be a US patent that
              anticipates several claims of a competitor's US patent. 
              The patent to be cited was only published after the filing
              of the competitor patent, the patent to be cited has an
              earliest date (provisional application filing date) that
              precedes the earliest date for the competitor patent, and
              thus is citable under 102 and 103.</div>
            <div><br>
            </div>
            <div>A submission under 35 USC 301/37 CFR 1.501 must contain
              a statement about the relevance of the cited
              publication(s) to at least one claim of the patent. No
              problem there, in this case.</div>
            <div><br>
            </div>
            <div>What I'm wondering about is the following: the
              competitor patent claims the benefit of a provisional that
              discloses X, but the patent also discloses X+Y, which
              means that the competitor patent is only entitled to the
              actual non-prov filing date for any claims on X+Y.</div>
            <div><br>
            </div>
            <div>We think the anticipatory patent already shows X+Y from
              its earliest date, viz. from before the filing of the
              competitor provisional. Thus, to make our case, it's not
              necessary to show that the competitor patent is only
              entitled to the later filing date for X+Y.  I think it
              would nevertheless be worthwhile to point this out in the
              35 USC 301/37 CFR 1.501 submission, if only to have that
              statement in the record in order to weaken the
              competitor's position.</div>
            <div><br>
            </div>
            <div>What I'm wondering is, since showing that X+Y isn't
              necessary in order to get the anticipatory patent admitted
              as prior art and to make the showing of anticipation,
              might the PTO bounce our submission for including
              extraneous material? As I read the statute and rule, I
              don't think we're precluded form including the extra
              information, but if anyone knows for sure the PTO will
              frown on this, I'd like to know beforehand.</div>
            <div><br>

            <div>(And FWIW, the client is still weighing whether or not
              to pony up the ex parte reexamination fee. It does not
              have the funds for an IPR.)</div>
