Appeal 2006-1454
Application 09/004,524
Patent 5,483,421
recapture analysis, North American Container has clarified the application of the
three-step framework analysis. North American Container holds that the “inner
walls” limitation (a portion of the issued claim that was added to the rejected claim
by amendment) was “subject matter that was surrendered during prosecution of the
original-filed claims.” 415 F.3d at 1350, 75 USPQ2d at 1557.
It is believed that the Substep (3)(a) rationale of the Eggert majority (1) is
not consistent with the rationale of the Federal Circuit in North American
Container and (2) should no longer be followed or be applicable to proceedings
before the USPTO.
