Office Action

§102 §103
DETAILED ACTION 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 . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 1/16/2026 has been entered. Response to Arguments Applicant's arguments filed 1/16/2026 have been fully considered. Rejection under 35 U.S.C. 102(a)(1) as being anticipated by or Mora et al (2012/0232652), in the alternative, under 35 U.S.C. 103 as obvious over Mora et al in view of Burnett et al (2009/0012372). Mora et al clearly teaches a shell comprising a first layer, a second layer and a filler. Further, said shell is round/spherical under 102/103. Third, the remainder of the limitations include, “wherein the viscosity of the fluid is configured to allow the fluid to respond to gravity to maintaining a symmetrical configuration of the shell about at least two planes of symmetry and maintain the round shape” is functional language. Under what gravity? Semi-floating in a preservative? When implanted? Neither Mora et al nor Burnett et al teach they are configured to not maintain a symmetrical configuration in response to gravity. Finally, “wherein the viscosity of the fluid is configured to allow the fluid to respond to gravity to maintaining a symmetrical configuration of the shell about at least two planes of symmetry and maintain the round shape” does not claim that the posterior side and the anterior side remain symmetrical after responding to gravity, the language claims only two planes of symmetry. For example, if a round shell was placed on a table under extremely high gravity producing a flat portion, the shell would still have an infinitive number of planes of symmetry despite a plane parallel to the flat portion not producing symmetrical halves. Claim Rejections - 35 USC § 102 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. Claim Rejections - 35 USC § 103 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 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. Claims 1-2, 4-9 and 14 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by or Mora et al (2012/0232652), in the alternative, under 35 U.S.C. 103 as obvious over Mora et al in view of Burnett et al (2009/0012372) or Power-Cooper et al (2020/0330216). Mora discloses a medical implant comprising a shell formed of a biocompatible material. Mora discloses that “the present implants are suitable for implantation in the human body and the flexible colored shell is accordingly sized and shaped” (par. 21) and that “typical long-term implantable devices, which are often selected for these procedures, include round, anatomical or molded silicone gel filled shapes” (par. 3). Merriam-Webster’s, synonym for “round” is a sphere (spherical). A sphere has an infinite number of planes of symmetry. PNG media_image1.png 340 1034 media_image1.png Greyscale Further, round can be defined as “spherical or shaped like a ball”. Therefore, Mora discloses that the implant can be round (sphere) in shape. Par. 67 of the instant application’s specification explains that round implants have three planes of symmetry with one corresponding to the equator of the implant. Therefore, it is inherent that the round implant of Mora has at least two planes of symmetry, one of which corresponds to an equator of the implant dividing a posterior side from and an anterior side. Mora also discloses the shell includes at least one first layer formed from at least one first material (i.e. par. 0014 silicone elastomer) and at least a second layer 2 arranged more inwardly relative to the at least one first layer (as shown in the bottom-right embodiment of fig. 1), the second layer formed from a second material (differently colored silicone elastomer, see pars. 14-15, 17, 20, claims 3-5). Mora also discloses the implant being “suitable for implantation in the human body” (par. 21), therefore, inherently discloses the implant can be either a breast implant, gluteal implant or tissue expander (which functions as a dissector); see par. 8. The at least one first layer and at least one second layer forming a cavity filled with silicone gel (see abstract) filler in contact with the at least one second layer; said filler includes a fluid (silicone gel) having a viscosity, the filler inherently is configured to cooperate with the at least one first layer and the at least one second layer. Wherein the viscosity of the fluid is configured to allow the fluid to respond to gravity to maintaining a symmetrical configuration of the shell about at least two planes of symmetry and maintain the round shape. This wherein clause is functional language. Under how much gravity? When semi-floating in a preserving fluid? When implanted? Mora et al does not teach the shell with the filler is configured not to maintain a symmetrical configuration in response to gravity. It is the examiner’s position that the implant of Mora et al fulfills this claim language and all limitations. Finally, said wherein clause can be interpreted as not pertaining to the posterior side and the anterior side remaining symmetrical but can be any other two planes remaining symmetrical after responding to gravity. For example, if a round shell was placed on a table under extremely high gravity, the shell may develop a flat portion in contact with the table. However, an infinitive number of planes of symmetry will still remain despite a plane parallel to the flat portion not produce symmetrical halves. In the alternative, under 35 U.S.C. 103 as obvious over Mora et al (US 20120232652) in view of Burnett et al (2009/0012372) or Power-Cooper et al (2020/0330216). If Mora et al does not inherently teach the medical implant includes at least two planes of symmetry: Burnett et al also teaches a silicone gel-filled implant. Par. 0081 of Burnett et al teaches a medical implant having “a spherical shell 4 (as would be the case for many breast implants and gastric balloons)”. Further, see round or symmetric in par. 0123. Further, Burnett et al teaches the filler can be a cured polymeric large silicones (par. 0004) which would have been obvious to have used in the combination medical implant configured to maintain a symmetrical configuration in response to gravity. Power-Cooper et al also teaches a spherical breast implant shown below and described in at least the abstract. PNG media_image2.png 767 545 media_image2.png Greyscale It would have been obvious to one skilled in the art to have made the implants of Mora et al spherical, round or symmetric having at least two planes of symmetry wherein one plane divides the posterior side from the anterior sided as taught by Burnett et al or Power-Cooper et al for a well-known medical implant shape. Claim 2 is rejected under both 102 and 103. Round, spherical, round or symmetric have three planes of symmetry, as evidenced by specification par. 67 of the instant application. Claim 4 is rejected under both the 102 and 103 rejections teaching round/spherical. Claim 5 is rejected under both the 102 and 103 rejections, Mora discloses the implant includes a shell and a filler (par. 14) and a patch (Mora claim 1). Claims 6 and 8 are rejected under both the 102 and 103 rejections. The implant is round/spherical which inherently has an infinite number of planes of symmetry that divide the implant into a posterior and an anterior half. Mora discloses the implant has a patch (Mora claim 1). There are a numerous number of planes of symmetry dividing the posterior and anterior sides such that the patch is located between an apex and the plane of symmetry. Claims 7-8 are rejected under 35 U.S.C. 103 only. Mora et al teaches a patch in at least claim 5. Burnett et al also teaches a patch 5. However, neither Mora et al, or Mora et al in view of Burnett et al, explicitly disclose a diameter of the patch. The Courts have held that “where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device” (see MPEP 2144.04(IV) (B)). It appears that the implant of Mora would operate equally as well with the claimed patch diameter since changing the patch diameter to be within the claimed range would not result in a change in the mechanics or function of the device. Further, the applicant has not disclosed that the claimed range solves any stated problem or is for any particular purpose, indicating simply that the patch diameter “may” be within the claimed range or even that it “may range from about 10 mm to about 40 mm” (specification par. 39). It would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to modify the patch diameter of Mora to be less than or equal to 30mm because it appears to be a mere difference in relative dimension which fails to patentably distinguish over Mora. Claim 9 is rejection under 35 U.S.C. 103 rejection only. Burnett et al provides evidence that a medical breast implant including a transponder (abstract, par. 104, fig. 9) are known in the art to include a transponder. See all rejections for claim 1 above. It would have been obvious to one of ordinary skill in the art to modify the implant of Mora et al to include a transponder, as taught by Burnett, to provide the implant with the capability “to communicate with an external device alerting a user or a healthcare provider that the integrity of the implant is failing” (Burnett par. 23). Claim 14 is rejected under both the 102 and 103 rejections, Mora discloses that the shell may include one low diffusion barrier layer that forms an innermost surface of the shell (pars. 14-15, bottom-right embodiment of fig. 1). Claim 11 is rejection under 35 U.S.C. 103 as obvious over Mora et al, or, Mora et al in view of Burnett et al (2009/0012372) or Power-Cooper et al, and further in view of Quiros et al (20150282926). Mora et al, or Mora et al in view of Burnett et al or Power-Cooper et al, do not disclose specifics of the texture of the outside surface of the implant. Quiros teaches a breast implant, in the same field of endeavor, that has multiple planes of symmetry and at least a first and second layer (par. 0031) and has a nano-textured or micro-textured outer surface (Quiros par. 0005 and 0030). It would have been obvious to one of ordinary skill in the art to have modified the outer surface of the implant of Mora, or Mora et al in view of Burnett et al, to include a nano-textured or micro-textured, as taught by Quiros, to provide a relatively smooth outer surface that negates the complications that can develop from aggressively textured outer surfaces, such as irritation of the local tissues (Quiros pars. 24 and 30). Allowable Subject Matter Claims 15, 18-19, 23, 26-28, 32-34 are allowed.
