Last Friday, In re Mostafazadeh was argued before the CAFC (argument here). The case explored the boundaries of the patent reissue recapture rule. At dispute in the appeal was whether or not the third step of the rule, as outlined in MPEP 1412.02, is tied to the “critical limitation” (i.e., originally surrendered subject matter) or not. {10:30 min. mark}
The three step analysis of In re Clement is as follows:
(1) first, we determine whether, and in what respect, the reissue claims are broader in scope than the original patent claims;
(2) next, we determine whether the broader aspects of the reissue claims relate to subject matter surrendered in the original prosecution; and
(3) finally, we determine whether the reissue claims were materially narrowed in other respects, so that the claims may not have been enlarged, and hence avoid the recapture rule. (emphasis added)
In considering the case, the CAFC found both the MPEP discussion of step (3) and BPAI decision on this point to be confusing. {14.50 min mark} Continue Reading Recapture Doctrine Before The CAFC
