Office Action

§101 §DP
DETAILED ACTION Examiner’s Comments The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. Column and line (or Paragraph Number) citations have been provided as a convenience for Applicants, but the entirety of each reference should be duly considered. Any recitation of a Figure element, e.g. “Figure 1, element 1” should be construed as inherently also reciting “and relevant disclosure thereto”. Specification The first paragraph of Applicants' specification should be updated to reflect the current status of any listed related U.S. patent applications. Statutory Double Patenting A rejection based on double patenting of the “same invention” type finds its support in the language of 35 U.S.C. 101 which states that “whoever invents or discovers any new and useful process... may obtain a patent therefor...” (Emphasis added). Thus, the term “same invention,” in this context, means an invention drawn to identical subject matter. See Miller v. Eagle Mfg. Co., 151 U.S. 186 (1894); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Ockert, 245 F.2d 467, 114 USPQ 330 (CCPA 1957). A statutory type (35 U.S.C. 101) double patenting rejection can be overcome by canceling or amending the claims that are directed to the same invention so they are no longer coextensive in scope. The filing of a terminal disclaimer cannot overcome a double patenting rejection based upon 35 U.S.C. 101. Claims 1 – 6 are rejected under 35 U.S.C. 101 as claiming the same invention as that of claims 1 - 6 of prior U.S. Patent No. 12,125,621 B2. This is a statutory double patenting rejection. Regarding claims 1 – 6, the Examiner believes that the claims in the present Application recite verbatim the subject matter of the claims in parent case 12,125,621 B2. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the claims at issue are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on a nonstatutory double patenting ground provided the reference application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO internet Web site contains terminal disclaimer forms which may be used. Please visit http://www.uspto.gov/forms/. The filing date of the application will determine what form should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to http://www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 1 – 6 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1 - 6 of U.S. Patent No. 12,125,621 B2 (the parent Application). Although the claims at issue appear to be exactly identical (see statutory double patenting rejection, above), the Examiner is applying this rejection, as well, in case a preliminary amendment had been filed but not matched with this Application or if the Examiner overlooked a minor difference in the claims (though careful review of the two claim sets _appears_ that they are identical). Finally, the Examiner notes that any amendment to distinguish from the prior claim set would move the double patenting rejection from the, above, statutory double patenting, into an obviousness double patenting rejection situation. As such, in the interest of expedited prosecution, the Examiner has set forth this rejection should Applicants desire to amend the claims and file a terminal disclaimer at the same time. As noted above, a terminal disclaimer alone is not sufficient to overcome a statutory double patenting rejection. Allowable Subject Matter The following is a statement of reasons for the indication of allowable subject matter: the subject matter of the present claims are deemed allowable for the same reasons as set forth in the parent Application. Regarding the ‘hand waving’ rejection set forth in the International Written Opinons provided on the submitted IDSs, the Examiner notes that there is no specificity to (1) add additional magnetic layers and, most importantly, to add these additional magnetic layers in such a way to meet the claimed relative permeability limitations with regard to each pair of adjacent layers starting from the first layer to the nth layer. As such, the Examiner maintains that under US doctrine of patentability, the present claims are allowable for the reason of record as there is no motivation to teach or render obvious the totality of the limitations of claim 1. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
