Office Action

§102
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. This office action is in response to applicant’s communication of 6/17/2022. Currently claims 1-10 are pending and rejected below. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of pre-AIA 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 – (b) the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country, more than one year prior to the date of application for patent in the United States. Claim(s) 1-5, 7, and 9-10 is/are rejected under pre-AIA 35 U.S.C. 102(b) as being anticipated by Harrison et al. (US 5,554,119). Harrison (as in figures 1-12) discloses a balloon (such as 210, 212, 214, 216, 218, 220) for an inflatable structure apparatus, comprising: a plurality of balloon segments (such as 210, 212, 214, 216, 218, 220) arranged into an annular balloon structure and attached to each other (see figure 11), wherein the plurality of balloon segments form one inflation/deflation volume (see balloon tubing as in figure 11 interior of 210), the balloon forms a central fluid passage (interior 224), and the balloon segments comprise cylindrical balloon segments or spiral ring balloon segments (note spiral shape as in figure 11). PNG media_image1.png 513 771 media_image1.png Greyscale Concerning claim 2 and comprising a plurality of flexion sections (see 222 sections between the balloons) connecting the cylindrical balloon segments with each other, wherein the diameter of the flexion sections is smaller than or equal to the diameter of the cylindrical balloon segments (note diameter as in figure 11 where the balloons are not is smaller than where the diameter where the balloons are). Concerning claim 3 and an annular balloon structure (see figure 1-8b) for an inflatable structure apparatus, comprising: a plurality of individual balloons (multiple 50/52 as in figure 8b for example) arranged into an annular structure and attached to each other wherein the annular balloon structure forms a central fluid passage (interior 58) and the individual balloons are essentially cylindrical balloons or toroidal balloons (note the balloons in figures 1-8b are donut or toroidal in shape), with at least one inflation/deflation port each (see figure 8b which shows an example of the inflation ports near 54 for example). Concerning claim 4 and the interior volumes of the individual balloons are connected together (note the common volume 56). Concerning claim 5 and a system, comprising the balloon as described in the rejection of claim 1 above and a shell (222) in the shape of a hollow cylinder (see figure 11 and 11a), entirely or partially covering the balloon segments (see figure 11-11a). Concerning claim 7 and the shell is sized to compress or squeeze the inflated balloon segments such that they are deformed (see para column 15 lines 5-60 examiner is of the position that the materials of the shell 222 are elastic in nature and that the device states that it collapses when deflated and it is the examiners position that in order for the balloons to collapse when deflated the shell which is made of a elastic material would compress or squeeze an inflated balloon segment). Concerning claim 9 and comprising a hollow shaft in the central fluid passage (note shaft such as 224 as formed in the central fluid passage). Concerning claim 10 and with spiral ring balloon segments; and a balloon strap attached to the balloon (see material as on sheath 222 between the balloon segments or material around 240 which examiner is of the position are straps of material that hold the balloon segments together). Allowable Subject Matter Claims 6 and 8 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
