Office Action

§103
DETAILED ACTION 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. Claim Rejections - 35 USC § 103 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) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over US 20190388118 A1 to Kirn et al. (Kirn) in view of US 20050049701 A1 to Brennan. Regarding claim 1: Kirn discloses: A device (figures 1-4) for removing a breast implant (I/M), fill material, and/or a capsule from a patient (D), comprising: a housing (12/14) having proximal (12) and distal (14) portions which together define an interior chamber (see the interior chamber A in figure 1 below) for receiving the breast implant (I/M), fill material, and/or capsule; a rigid ring (26) fixed to the proximal portion (12) and defining a funnel (funnel of outer lip 32 (flared, rounded, or rolled outer lip)(¶0048)) for deforming and guiding the breast implant (I/M), fill material, and/or capsule toward an inlet (see the inlet B in figure 1 below) of the interior chamber (A in figure 1 below); and a suction port (34). Kirn fails to disclose: The funnel having a continuously tapering inner diameter extending from a proximal end of the funnel toward the inlet. Brennan teaches: A breast augmentation method/device that includes a housing (90) with an interior chamber (90). Further, the system includes a funnel (112) that includes a continuously tapering inner diameter (as shown in figure 4) extending from a proximal end (see the proximal end J in figure 3 below) of the funnel toward the inlet (106) of the interior chamber. The reference further indicates the funnel (funnel shape) aids in directing the breast implant (70) into the interior chamber (¶0007 and ¶0035). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Kirn to further modify the funnel in Kirn to extend from the proximal end of the funnel to the inlet of the interior chamber as taught Brennan so the funnel shape aids in directing the breast implant into the interior chamber (Brennan, ¶0007 and ¶0035).

Regarding claim 3: Kirn discloses: The device of claim 2, wherein an inner diameter (see the inner diameter of 14 as shown in figure 1 above) of the distal portion (14) of the housing (12/14) decreases (see the decrease in diameter form point F to G in figure 1 above) from a proximal end (see the proximal end F in figure 1 above) of the distal portion (14) of the housing (12/14) to a distal end (see the distal end G in figure 1 above) of the distal portion (14) of the housing (12/14). Regarding claim 4: Kirn discloses: The device of claim 3, wherein an inner diameter (the inner diameters at points E and F are the same/overlap since they mate as shown in figure 1 above) of a distal end (end E in figure 1 above) of the proximal portion (12) of the housing (12/14) and an inner diameter of a proximal end (end F in figure 1 above) of the distal portion (14) of the housing (12/14) are the same. Regarding claim 5: Kirn discloses: The device of claim 4, wherein the proximal (12) and distal (14) portions of the housing (12/14) are separable and are separated (“Of course, other types of mechanical connections may be utilized in lieu of the threaded mechanism in alternate embodiments such as, but not limited to, press fit connections, friction fit connections, butt connections with a separate connection ring, or a compression band with each sufficient to maintain the two portions 12, 14 in substantially parallel alignment to ensure a good seal”, ¶0052) by a connecting portion (see the connecting portion H in figure 1 above) having an inner diameter (inner diameter of 12 and 14 at the point that the mate as shown in figure 1 above) substantially the same from a proximal end to a distal end of the connecting portion (see the diameters of the mating portions as shown in figure 1 above at points E and F that are the same allowing for mating of 12 and 14). Regarding claim 6: Kirn discloses: The device of claim 1, wherein a narrowest inner diameter (see the diameter at location B) of the proximal portion (12) of the housing (12/14) is substantially the same (the diameter of the two is the same since the two components blend into one another and therefore must have and overlapping diameter as shown in figure 1 above) as the narrowest inner diameter (see the diameter at lip 32) of the funnel (funnel of outer lip 32) and increases (see increase in diameter form B to E as shown in figure 1 above) from a proximal end (see the proximal end B in figure 1 above) of the proximal portion (12) toward a distal end (see the distal end E in figure 1 above) of the proximal portion (12). Regarding claim 7: Kirn discloses: The device of claim 1, wherein each of the proximal (12) and distal (14) portions of the housing (12/14) provide at least 25% of the total volume (12 and 14 define the whole volume of the interior chamber A as shown in figure 1) of the interior chamber (A in figure 1 above). Regarding claim 8: Kirn discloses: A device for removing a breast implant (I/M), fill material, and/or a capsule from a patient (D), comprising: a housing (12/14) having proximal (12) and distal (14) portions which together define an interior chamber (A in figure 1 above) for receiving the breast implant (I/M), fill material, and/or capsule; a rigid ring (26) attached to the proximal portion (12) and defining a continuously tapering funnel (see the continuously tapering inner diameter of lip 32 from proximal end D to the distal end C (in figure 2 above) which aligns with ¶0048 which indicates lip 32 can be flared (funnel shaped) and as further evidenced by Self which shows a suction cup with a flared end (128; see ¶0011 where this end is described as flared) that is funneled shaped with a continuously tapering inner diameter from a proximal end to a distal end) for guiding the breast implant (I/M), fill material, and/or capsule toward an inlet (see the inlet B in figure 1 above) of the interior chamber (A in figure 1 above); and a suction port (34), wherein an inner diameter (see the inner diameter of 14 as shown in figure 1 above) of the distal portion (14) of the housing (12/14) decreases (see the decrease in diameter form point F to G in figure 1 above) from a proximal end (see the proximal end F in figure 1 above) toward a distal end (see the distal end G in figure 1 above) of the distal portion (14) of the housing (12/14). Kirn fails to disclose: The funnel having a continuously tapering inner diameter extending from a proximal end of the funnel toward the inlet. Brennan teaches: A breast augmentation method/device that includes a housing (90) with an interior chamber (90). Further, the system includes a funnel (112) that includes a continuously tapering inner diameter (as shown in figure 4) extending from a proximal end (see the proximal end J in figure 3 below) of the funnel toward the inlet (106) of the interior chamber. The reference further indicates the funnel (funnel shape) aids in directing the breast implant (70) into the interior chamber (¶0007 and ¶0035). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Kirn to further modify the funnel in Kirn to extend from the proximal end of the funnel to the inlet of the interior chamber as taught Brennan so the funnel shape aids in directing the breast implant into the interior chamber (Brennan, ¶0007 and ¶0035). Regarding claim 9: Kirn discloses: The device of claim 8, wherein inner diameters (see the inner diameter of 12 and 14 as shown in figure 1 above) of a distal end (end E in figure 1 above) of the proximal portion (12) of the housing (12/14) and an inner diameter of a proximal end (end F in figure 1 above) of the distal portion (14) of the housing (12/14) are the same (the inner diameters at points E and F are the same/overlap since they mate as shown in figure 1 above) of the distal end (end E in figure 1 above). Regarding claim 10: Kirn discloses: The device of claim 8, wherein the proximal (12) and distal (14) portions of the housing (12/14) are separable and are separated (“Of course, other types of mechanical connections may be utilized in lieu of the threaded mechanism in alternate embodiments such as, but not limited to, press fit connections, friction fit connections, butt connections with a separate connection ring, or a compression band with each sufficient to maintain the two portions 12, 14 in substantially parallel alignment to ensure a good seal”, ¶0052) by a connecting portion (see the connecting portion H in figure 1 above) having a substantially uniform inner diameter (inner diameter of 12 and 14 at the point that the mate as shown in figure 1 above). Regarding claim 11: Kirn discloses: The device of claim 8, wherein a narrowest inner diameter (see the diameter at location B) of the proximal portion (12) of the housing (12/14) is substantially the same (the diameter of the two is the same since the two components blend into one another and therefore must have and overlapping diameter as shown in figure 1 above) as a narrowest inner diameter (see the diameter at lip 32) of the funnel (funnel of outer lip 32) and increases (see increase in diameter form B to E as shown in figure 1 above) from a proximal end (see the proximal end B in figure 1 above) of the proximal portion (12) to a distal end (see the distal end E in figure 1 above) of the proximal portion (12). Regarding claim 12: Kirn discloses: The device of claim 8, wherein each of the proximal (12) and distal (14) portions provide at least 25% of the total volume (12 and 14 define the whole volume of the interior chamber A as shown in figure 1) of the interior chamber (A in figure 1 above). Regarding claim 13: Kirn discloses: A device for removing a breast implant (I/M), fill material, and/or a capsule from a patient (D), comprising: a housing (12/14) having proximal (12) and distal (14) portions separated by a central portion (see the connecting portion H in figure 1 above) which together define an interior chamber (A in figure 1 above) having a total volume for receiving the breast implant (I/M), fill material, and/or capsule, each of the proximal (12) and distal (14) portions of the housing (12/14) providing at least 25% of the total volume (12 and 14 define the whole volume of the interior chamber A as shown in figure 1) of the interior chamber (A in figure 1 above); a rigid (26) ring attached to a proximal end (see the proximal end B in figure 1 above) of the proximal portion (12) and defining a continuously tapering funnel (see the continuously tapering inner diameter of lip 32 from proximal end D to the distal end C (in figure 2 above) which aligns with ¶0048 which indicates lip 32 can be flared (funnel shaped) and as further evidenced by Self which shows a suction cup with a flared end (128; see ¶0011 where this end is described as flared) that is funneled shaped with a continuously tapering inner diameter from a proximal end to a distal end) having a narrowing inner diameter (funnel of outer lip 32 (flared, rounded, or rolled outer lip)(¶0048)) extending from the proximal end (B in figure 1 above) for guiding the breast implant (I/M), fill material, and/or capsule toward an inlet (see the inlet D in figure 2 above) of the housing (12/14); and a suction port (34). Kirn fails to disclose: The funnel having a continuously tapering inner diameter extending from a proximal end of the funnel toward the inlet. Brennan teaches: A breast augmentation method/device that includes a housing (90) with an interior chamber (90). Further, the system includes a funnel (112) that includes a continuously tapering inner diameter (as shown in figure 4) extending from a proximal end (see the proximal end J in figure 3 below) of the funnel toward the inlet (106) of the interior chamber. The reference further indicates the funnel (funnel shape) aids in directing the breast implant (70) into the interior chamber (¶0007 and ¶0035). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Kirn to further modify the funnel in Kirn to extend from the proximal end of the funnel to the inlet of the interior chamber as taught Brennan so the funnel shape aids in directing the breast implant into the interior chamber (Brennan, ¶0007 and ¶0035). Regarding claim 14: Kirn discloses: The device of claim 13, wherein an inner diameter (see the inner diameter of 12 as shown in figure 1 above) of the proximal portion (12) of the housing (12/14) increases (see the increase in diameter from B to E as shown in figure 1 above) from the inlet (see the inlet B in figure 1 above) of the housing (12/14) to the central portion (see the distal end E as shown in figure 1 above) of the housing (12/14). Regarding claim 15: Kirn discloses: The device of claim 14, wherein an inner diameter (see the inner diameter of 14 as shown in figure 1 above) of the distal portion (14) of the housing (12/14) decreases (see the decrease in diameter form point F to G in figure 1 above) from a proximal end (see the proximal end F in figure 1 above) of the distal portion (14) of the housing (12/14) toward a distal end (see the distal end G in figure 1 above) of the distal portion (14) of the housing (12/14). Regarding claim 16: Kirn discloses: The device of claim 15, wherein the inner diameters (the inner diameters at points E and F are the same/overlap since they mate as shown in figure 1 above) of the distal end (end E in figure 1 above) of the proximal portion (12) of the housing (12/14) and the proximal end (end F in figure 1 above) of the distal portion (14) of the housing (12/14) are the same. Regarding claim 17: Kirn discloses: The device of claim 16, wherein the proximal (12) and distal (14) portions of the housing (12/14) are separable (“Of course, other types of mechanical connections may be utilized in lieu of the threaded mechanism in alternate embodiments such as, but not limited to, press fit connections, friction fit connections, butt connections with a separate connection ring, or a compression band with each sufficient to maintain the two portions 12, 14 in substantially parallel alignment to ensure a good seal”, ¶0052) and the inner diameters (inner diameter of 12 and 14 at the point that the mate as shown in figure 1 above) of the distal end (end E in figure 1 above) of the proximal portion (12) of the housing (12/14) and the proximal end (end F in figure 1 above) of the distal portion (14) of the housing (12/14) are substantially the same (the inner diameters at points E, F and H are the same/overlap since they mate as shown in figure 1 above) as an inner diameter (center of 12/14 or H in figure 1 above) of the central portion of the housing (12/14). Regarding claim 18: Kirn discloses: The device of claim 13, wherein a narrowest inner diameter (see the diameter at location B) of the proximal portion (12) of the housing (12/14) is substantially the same (the diameter of the two is the same since the two components blend into one another and therefore must have and overlapping diameter as shown in figure 1 above) as a narrowest inner diameter (see the diameter at lip 32) of the funnel (funnel of outer lip 32) and increases (see increase in diameter form B to E as shown in figure 1 above) from a proximal end (see the proximal end B in figure 1 above) of the proximal portion (12) of the housing (12/14) to a distal end (see the distal end E in figure 1 above) of the proximal portion (12) of the housing (12/14).

Response to Arguments Applicant’s arguments, see remarks, filed 6/17/26, with respect to the rejection(s) of claim(s) 1-20 under 35 USC 103 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of US 20190388118 A1 to Kirn et al. (Kirn) in view of US 20050049701 A1 to Brennan. Regarding the 35 USC 103 rejection with Kirn: First, the applicant argues that in Kirn does not mention or teach a funnel (see page 7 of the remarks). However, the office is not persuaded by this argument as indicated above. While the reference does not explicitly state a funnel it describes the shape of the funnel when it indicates the end of Kirn maybe “flared” which is the same as a funnel shape (Kirn, ¶0048). For this reason, the above rejection is made with Kirn by modifying the funnel (flared) lip/end. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
