Office Action

§112 §DP
DETAILED ACTION Notice of Pre-AIA or AIA Status 1. 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. Double Patenting 2. 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 conflicting claims 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); 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 nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). 3. Claims 21-40 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-17 of U.S. Patent No. 12,226,269. - Application claims 21-36 correspond to Patent claims 1-15. - Application claims 37-38 correspond to Patent claim 16. - Application claims 39-40 correspond to Patent claim 17. Although the claims at issue are not identical, they are not patentably distinct from each other because: The difference between the application claims and the patent claims lies in the fact that the patent claims include more element(s) and are thus much specific. For example: The patent independent claim 1 includes “(iii) a third surface positioned adjacent to the second surface and opposite to the first surface” and “(v) a second plurality of openings passing through the second surface, the second plurality of openings being configured for positioning on a buccal side of the alveolar ridge of the patient”, the underlined features are excluded from the application corresponding claim 21. Furthermore, the application claims 21-40 recite the element “(b) a placement-checking element” (claim 21 line 24) which is considered to be equivalent to or broader than the element “(b) a prosthetic” recited in the corresponding patent claims because a prosthetic essentially is or can serve as a placement-checking element. The application claim 38 recites the element “a buccal portion” which is considered to be broader than the element “a buccal wall” recited in patent claim 16. That is, “a buccal wall” is much specific than a “buccal portion”. Thus the invention of the patent claims is in effect a “species” of the “generic” invention of the application claims. It has been held that the generic invention is “anticipated” by the “species”. See In re Goodman, 29 USPQ2d 2010 (Fed. Cir. 1993). Since the application claims are anticipated by the patent claims, they are not patentably distinct from the patent claims. Claim Rejections - 35 USC § 112 4. The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. 5. Claims 21-36 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Claim 21 recites “a first plurality of openings passing through the first surface and through the second surface” (claim 21 lines 19-20) which lacks support from the specification. The specification discloses the bone foundation guide 20 having a first/front surface 24 and a second/top surface 34 of buccal wall 24, wherein a first plurality of openings (apertures 38 in Fig. 1, or channels 226 in Fig. 29) passing through the first/front surface 24, not also the second/top surface 34. Therefore, neither the drawings nor the written description describes the underlined features in the recitation “the first plurality of openings passing through the first/front buccal surface 24 and through the second/top surface 34”. Conclusion 6. The pending claims are rejected under Double Patenting and 35 U.S.C. 112 as detailed above. No grounds of rejection under prior art.
