Office Action

§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 . 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) 15-18, 21-23 and 27 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sato et al. (US 2012/0040113) in view of West et al.(US 7,819,251). In re claim 15: A multilayer laminate capable of producing a tubular container ([0098]), comprising at least one paper layer ([0052]), a sealable exposed polymer layer on one side of the at least one paper layer, and a polymer coating from an olefin-based material applied directly on the at least one paper layer on an other side of the at least one paper layer facing away from the sealable polymer layer ([0054] – [0057]), wherein the polymer coating is a protective polymer coating with a weight per area in the range from 0.5 g/m2 to 4.9 g/m2 ([0074]), and where the protective polymer coating is either exposed towards the outside or carries applied printing (see [0056], [0098], [0100] and [0103]). Sato et al. discloses the claimed invention as discussed above with the exception of the following specific limitation that is suggested by West et al.: West et al. teaches the provision of a multilayer laminate tubular container which using a heavy thickness of paper depending on the desired rigidity of the tubular container in combination with very thin layers of protective coating starting at 0.0001mm. With this in mind, it would have been obvious to one of ordinary skill in the art at the time of the invention to modify the multilayer laminate of Sato et al. with such a weight fraction of the paper as suggested by West et al. This combination teaches the general conditions of the claimed invention except for the express disclosure of the total weight per area of the laminate is at least 75%. It would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to incorporate at least one paper layer out of the total weight per area of the laminate is at least 75%, since the claimed values are merely an optimum or workable range. It has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. In re claim 16: the protective polymer coating comprises at least one acid-modified olefin or consists of such ([0056]). In re claim 17: the protective polymer coating exhibits a weight per area in the range from 1 g/m2 to 2.5 g/m2 ([0074]). In re claim 18: the protective polymer coating carries applied printing which is formed from a layer of overprint varnish and a layer region of printing inks arranged between the overprint varnish layer and the protective polymer coating, where the overprint varnish is exposed with its surface facing away from the at least one paper layer (see [0056], [0074], [0098], [0100] and [0103]). In re claim 21: the overprint varnish is an acryl-based varnish ([0103]). In re claim 22: the sealable exposed polymer layer comprises a polyethylene and/or a cyclo-olefin copolymer or consists of such material (see [0056], [0065], [0088], and [0096]). In re claim 23: the laminate exhibits at least one barrier layer for reducing an oxygen permeability and/or a water vapor permeability of the laminate, where the at least one barrier layer comprises a vinyl alcohol polymer and/or a metallization and/or a metal oxide or is formed from such material ([0065] -([0070]). In re claim 27: the laminate exhibits more than one paper layer, where one of the paper layers carries the barrier layer ([0065] -([0070]). 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) 19-20 and 24-25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sato et al. (US 2012/0040113) in view of West et al. (US 7,819,251). Sato et al. discloses the claimed invention as discussed above with the exception of the following specific limitations: In re claim 19: the applied printing exhibits a thickness of less than 3 µm. Sato et al. in view of West et al. teaches the general conditions of the claimed invention except for the express disclosure of a printing thickness of less than 3 µm. It would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to incorporate a printing thickness of less than 3 µm, since the claimed values are merely an optimum or workable range. It has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. In re claim 20: the overprint varnish is an acryl-based varnish ([0103]). In re claim 24: the laminate exhibits a weight per area in the range from 200 g/m2 to 450 g/m2. Sato et al. in view of West et al. teaches the general conditions of the claimed invention except for the express disclosure of a laminate weight per area in the range from 200 g/m2 to 450 g/m2. It would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to incorporate a laminate weight per area in the range from 200 g/m2 to 450 g/m2, since the claimed values are merely an optimum or workable range. It has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. In re claim 25: the weight per area of the at least one paper layer in the laminate lies in the range from 80 g/m2 to 350 g/m2. Sato et al. in view of West et al. teaches the general conditions of the claimed invention except for the express disclosure of a laminate weight per area in the range from 80 g/m2 to 350 g/m2. It would have been obvious to one having ordinary skill in the art at the time the invention was effectively filed to incorporate a laminate weight per area in the range from 80 g/m2 to 350 g/m2, since the claimed values are merely an optimum or workable range. It has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art. In re Aller, 105 USPQ 233. Claim(s) 28-29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Sato et al. (US 2012/0040113) in view of West et al.(US 7,819,251) and in further view of Yoshida et al. (US 2018/0099787). Sato et al. in view of West et al. teaches the claimed invention as discussed above with the exception of the following specific limitation that is taught by Yoshida et al.: In re claim 28: A tubular body formed from a laminate according to Claim 15, where the tubular body 10a comprises a tube laminate blank which is rolled about a tubular body longitudinal axis, where end regions of the tube laminate blank which face towards one another in the circumferential direction about the tubular body longitudinal axis are bonded with one another through sealing 11, forming a sealed seam 11 running in the direction along the tubular body 10a longitudinal axis, where the sealed seam 11 either i) is an overlap sealed seam (fig. 4a) in which the sealable polymer layer overlaps the protective polymer coating in an overlap region, where the overlap region extends in the circumferential direction and in the direction along the tubular body longitudinal axis and where the sealable polymer layer and the protective polymer coating are firmly bonded in the overlap region with one another (see [0092] and [0093] of Yoshida et al.), or ii) is a butt sealed seam, in which the end regions which face towards one another in forming a butt joint which proceeds in the direction along the tubular body longitudinal axis and radially away from the tubular body longitudinal axis, approach one another where the butt joint on at least one radial side with respect to the tubular body longitudinal axis is covered by a sealing strip which extends along the butt joint, spans the butt joint in the circumferential direction, and on each of the two circumferential sides of the butt joint is firmly bonded with an exposed surface section of the tube laminate in the end regions. In re claim 29: a tube top 20 bonded with the tubular body 10a which exhibits at least one exposed surface from a polyolefin encircling the tubular body longitudinal axis, where an exposed surface of the tubular body 10a is firmly bonded through sealing with the encircling exposed surface of the tube top 20 (see [0093] of Yoshida et al.). It would have been obvious to one of ordinary skill in the art at the time the invention was effectively filed modify the multilayer laminate container of Sato et al. in view of West et al. with the tube container as taught Yoshida et al. in order to allow users to squeeze products out of the container when in use (see [0006] of Yoshida et al.). Response to Arguments Applicant’s arguments with respect to the claim(s) have been considered but are moot because the new ground of rejection does not rely on the reference combination applied in the prior rejection of record. 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.
