subsequent and binding Federal Circuit event has overtaken the rationale upon which Gustavsson is based. The event was In re McGrew, 120 F.3d 1236, 43 USPQ2d 1632 (Fed. Cir. 1997), in which the Federal Circuit made it crystal clear that § 135(b) is a statute of repose. 120 F.3d at 1237, col. 2, 43 USPQ2d at 1634, col. 1.
