Appeal 2007-0040 Application 10/170,069 Patent 6,073,699 (12) Materially Narrowed in Overlooked Aspects When reissue claims are narrower than the patent claims with respect to features other than the surrender generating feature, then the reissue claims may be materially narrowed relative to the claims prosecuted and issued in the patent, thereby avoiding the recapture rule. The Federal Circuit in North American Container characterized the second and third steps in applying the recapture rule as determining “whether the broader aspects of the reissue claims relate to subject matter surrendered in the original prosecution” and “whether the reissued claims were materially narrowed in other respects, so that the claims may not have been enlarged, and hence avoid the recapture rule.” 415 F.3d at 1349, 75 USQ2d at 1556 (emphases added), citing for authority Pannu, 258 F.3d at 1371, 59 USPQ2d at 1600. The language “materially narrowed in other respects” relates for comparison back to the earlier recited “broader aspects of the reissued claims” (i.e., surrendered subject matter). Thus, by using the phrase “in other respects” to modify “materially narrowed,” the court makes clear that reissue claims will avoid the recapture rule if materially narrowed in respects other than the broader aspects relating to surrendered subject matter. This plain language in North American Container indicates that the recapture rule is avoided if the added limitations are a materially narrowing in respects other than the broader aspects relating to surrendered subject matter. - 33 -Page: Previous 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 Next
