This action is in response to the filing on 10/8/20252. Since the previous filing, claims 1, 3, 6, 11-13 and 15-19 have been amended, claims 2, 5 and 7-10 have been cancelled and no claims have been added. Thus, claims 1, 3, 4, 6 and 11-20 are pending in the application. In regards to the previous Claim Objections, Applicant has amended to overcome these objections and they are therefore withdrawn with new objections entered as needed. In regards to the previous 112 Rejections, Applicant has amended to overcome these rejections and they are therefore withdrawn with new rejections added as needed. In regards to previous 102 and 103 Rejections, Applicant has amended to overcome these rejections and they are therefore withdrawn with new rejections entered below. Claim Objections Claims 6 are objected to because of the following informalities: Claim 6 should depend from claim 1 and not cancelled claim 2 Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(d): (d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph: Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers. Claim 6 is rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claim upon which it depends, or for failing to include all the limitations of the claim upon which it depends. Claim 6 repeats the limitation of a “seal structure removably disposed within at least one of said supplementary ports” as seen in preceding claim 1 line 14-15. Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
