Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Claims 1-20 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of copending Application No. 18/134,243 (reference application). Although the claims at issue are not identical, they are not patentably distinct from each other because each claims a radiation shielding material and composition comprising heavy metals in a matrix polymer.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
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 (i.e., changing from AIA to pre-AIA ) 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.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1, 3-9, 15-20 is/are rejected under 35 U.S.C. 102((a)(1)) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Rebar et al, U.S. Patent Application Publication No. 2014/0117288.
Rebar discloses a filled composition for radiation shielding. The composition can be used to form garments. See paragraph 0002. The garments can comprise a filled composition including at least one polymer and one metal containing filler. See paragraph 0005. The polymers can be polyolefins including polyolefin copolymers and elastomeric polyolefins. See paragraph 0005. The metal filler can comprise Sb, W, Ba, Pb, Bi, and alloys, oxides and salt thereof or can be substantially free of Pb. See paragraph 0009. The polymer component can be from 0.4-35 Wt% and the metal containing filler can comprise 50-95.5 wt%. See paragraph 0011. The composition can further comprise additives paraffinic oil, aromatic oil, antioxidants, compatibilizers, adhesion promoters and processing aids. See paragraph 0014. When the composition is formed into a garment, the structure can further comprise at least one layer of fabric. See paragraph 0015. The composition can be crosslinked or uncrosslinked. See paragraph 0015. The fabric can nylon or polyester. See paragraph 0030. The layer of fabric can have a thickness of15-25 mils. See paragraph 0030. The metal containing fillers can be combined, for example Sb and Bi, Sb and W, Sb and BaSO4, Bi and BaSO4 and any other mixture. See paragraph 0047. The particles size can be 0.1-74 microns. Note that a 0.1 micron particle is construed as having nano dimensions. See paragraph 0047. The garments can block X-rays. See paragraph 0076. The structure can comprise a plurality of layers to provide improved properties. See paragraph 0072. The heavy metals have a Z number of greater than 50. See paragraph 0046. The particles can have a range of sizes. See examples. The composition can further comprise fiber fillers such as microfibers of nylon, polyester or PTFE which corresponds to the limitations of claim 6. See paragraph 0051.
With regard to claim 7, either the filler fibers or the fabric onto which the composition is applied can correspond to a fiber onto which the heavy metal particles are coated.
With regard to the limitation that the composition provides protection from both primary and scatter x-rays, since Rebar teaches providing protection from x-rays generally and teaches the same structure, it is reasonable to expect that the composition of Rebar provides protection from primary and scatter x-rays, or, in the alternative, it would have been obvious to have selected the appropriate composition and mixture which produced the desired protection.
Claim(s) 1-5, 9-10, 16-17, 19 is/are rejected under 35 U.S.C. 102((a)(1)) as anticipated by or, in the alternative, under 35 U.S.C. 103 as obvious over Khandkar et al, U.S. Patent Application Publication No. 2015/0083941.
Khandkar discloses radiation shielding systems. See abstract. The systems can include heavy metal particles disposed in an polymeric binder combined with fabrics or other reinforcing materials. The particles can include metals having a X number, of 56 or greater and include the claimed types of metals. See paragraph 0059. The binder can include polyvinyl chloride or polyurethane. See paragraph 0060. The binder may be present in amounts of 3- 25% while the heavy metal particles are present in amounts of up to 97%. See paragraph 0061. The particles can be uniformly dispersed or dispersed so as to form a gradient. See paragraph 0047.
With regard to the limitation that the composition provides protection from both primary and scatter x-rays, since Khandkar teaches providing protection from x-rays generally and teaches the same structure, it is reasonable to expect that the composition of Rebar provides protection from primary and scatter x-rays, or, in the alternative, it would have been obvious to have selected the appropriate composition and mixture which produced the desired protection.
Claim(s) 10-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Rebar et al, U.S. Patent Application Publication No. 2014/0117288.
Rebar discloses a composition as set forth above.
Rebar differs from the claimed invention because while it teaches forming blends of more than one of the lead free metal particles, it does not teach the claimed proportions.
However, since Rebar teaches forming blends generally, it would have been obvious to have formed blends as taught by Rebar and varied the relative proportions of the components in order to arrive at a protective material which provided the desired level of protection.
Applicant's arguments filed 11/4/25 have been fully considered but they are not persuasive.
With regard to the obviousness-type double patenting rejection, Applicant argues that the copending application requires lead while the instant application excludes lead. However, since lead is a well-known and conventional radiation shielding material with known benefits and drawbacks, the person of ordinary skill considering the claims of ‘243 would have been able to select to use lead or a combination of the other heavy metals claimed excluding lead to form a radiation shielding material.
With regard to both art rejections, Applicant argues that the applied art does not teach the specific arrangement of the materials as claimed. However, the claims do not recite any structure regarding the arrangement of materials. Further, the specification does not teach any special method of arranging the at least two metals other than by mixing, blending, or compounding the metals with the materials of the matrix. See paragraph 0196 of the instant specification. Since this is the same method employed in the prior art references, which also use the same materials, there is a reasonable basis to expect that the claimed arrangement would be present and that the materials of the prior art would have the claimed properties, since like materials must have like properties.
Applicant’s amendments have overcome the 112 rejections.
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
