Office Action

§102
DETAILED ACTION The communication dated 10 / 18 /20 23 has been entered and fully considered. Claims 1-4 are currently pending. 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. 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. Claim Rejections - 35 USC § 102 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. Claims 1-4 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by R amanan et al. U.S. Publication 2020/0237607 (henceforth referred to as Ramanan) . As for claim 1 , Ramanan teaches a leg massager (Fig. 22: part 22004) comprising: a flexible foot enclosure ( Fig. 22: part 22004 -C ) , having a lower end and an upper end, comprising a foot internal volume; a flexible calf enclosure ( Fig. 22: part 22004 -B specifically the lower portion) , having a lower end and an upper end, comprising a calf internal volume; a flexible knee portion ( Fig. 22: part 22004-B specifically the upper portion ) , having a lower end and an upper end; a flexible thigh enclosure ( Fig. 22: part 22004 -A) , having a lower end and an upper end, comprising a thigh internal volume; at least one zipper (paragraph [0359]) ; wherein, the upper end of the foot enclosure connects the lower end of the calf enclosure, the upper end of the calf enclosure connects the lower end of the knee portion, the upper end of the knee portion connects the lower end of the thigh enclosure (Fig. 22) , at least one zipper adapts and runs along the leg massager from the foot enclosure to the thigh enclosure through the calf enclosure and the knee portion ( paragraph [0359] ; Fig. 22) . As for claim 2 , Ramanan further teaches a means for providing pressurized fluid (Fig. 22: part 1002) ; a first fluid passage for supplying and removing fluid between the means for providing pressurized fluid and the foot internal volume (Fig. 22: parts 1006, 22008-A, 22442-A, 22008-B, 22422-B, and 22008-C) ; a second fluid passage for supplying and removing fluid between the means for providing pressurized fluid and the calf internal volume (Fig. 22: parts 1006, 22008-A, 22442-A, and 22008-B) ; a third fluid passage for supplying and removing fluid between the means for providing pressurized fluid and the thigh internal volume (Fig. 22: parts 1006 and 22008-A) . As for claim 3 , Ramanan further teaches a first valve (Fig. 22: part 22008-C) , connected between the means for providing pressurized fluid and the first fluid passage for opening and closing the throw of the fluid into the foot internal volume; a second valve (Fig. 22: part 22008- B ) , connected between the means for providing pressurized fluid and the second fluid passage for opening and closing the throw of the fluid into the calf internal volume; a third valve (Fig. 22: part 22008- A ) , connected between the means for providing pressurized fluid and the third fluid passage for opening and closing the throw of the fluid into the thigh internal volume. As for claim 4 , Ramanan further teaches a controller ( Fig. 22: part 1002 ) configured to control the open and close of the first valve, second valve and third valve.
