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) 20-26, 31 is/are rejected under 35 U.S.C. 103 as being unpatentable over Garben in view of Sardari et at. (US 20180264225 A1) (“Sardari”). Re Claim 20, Garben fails to disclose wherein the filling surface is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface, and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a1, Fig. 5e) is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface (as filling start and mot pressure applied to 612 wall ¶0144), and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface (and wherein as 607b is capable to be move due to the controlled pressured in 603-2 see ¶0144). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so that the filling surface is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface, and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144). Re Claim 21, Garben fails to disclose wherein the first angular amount is substantially equal to the second angular amount. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a1, Fig. 5e) is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface (as filling start and mot pressure applied to 612 wall ¶0144), and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface (and wherein as 607b is capable to be move due to the controlled pressured in 603-2 see ¶0144) and wherein the first angular amount is substantially equal to the second angular amount ( the angular amount is the same (Fig 5f and Fig. 5g). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so that the first angular amount is substantially equal to the second angular amount as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144). Re Claim 22 Garben fails to disclose wherein the first angular amount varies by no more than twenty percent of the second angular amount or the second angular amount varies by no more than twenty percent of the first angular amount. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a1, Fig. 5e) is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface (as filling start and mot pressure applied to 612 wall ¶0144), and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface (and wherein as 607b is capable to be move due to the controlled pressured in 603-2 see ¶0144) and the first angular amount varies by no more than twenty percent of the second angular amount or the second angular amount varies by no more than twenty percent of the first angular amount (the angular amount is the same (Fig 5f and Fig. 5g). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so that the first angular amount varies by no more than twenty percent of the second angular amount or the second angular amount varies by no more than twenty percent of the first angular amount as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144). Re Claim 23, Garben fails to disclose wherein the filling surface is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface, and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a1, Fig. 5e) is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface (as filling start and mot pressure applied to 612 wall ¶0144), and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface (and wherein as 607b is capable to be move due to the controlled pressured in 603-2 see ¶0144). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so that the filling surface is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface, and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144). Re Claim 24, Garben fails to disclose wherein the first angular amount is different from the second angular amount. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a1, Fig. 5e) is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface (as filling start and mot pressure applied to 612 wall ¶0144), and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface (and wherein as 607b is capable to be move due to the controlled pressured in 603-2 see ¶0144) and wherein the first angular amount is different from the second angular amount ( the angular amount is the different when the wall 607b is flexible ¶0151 and the Fig 5f and Fig. 5g). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so wherein the first angular amount is different from the second angular amount as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144). Re Claim 25, Garben fails to disclose wherein a magnitude of the first angular amount is greater than a magnitude of the second angular amount. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a1, Fig. 5e) is configured to be out of plumb by a first angular amount when the gas removal apparatus is arranged in the liquid receiving position on a level surface (as filling start and mot pressure applied to 612 wall ¶0144), and wherein each of at least one of the one or more first contact surfaces is out of plumb by a second angular amount when the gas removal apparatus is arranged in the another position different from the liquid receiving position on the level surface (and wherein as 607b is capable to be move due to the controlled pressured in 603-2 see ¶0144) and wherein a magnitude of the first angular amount is greater than a magnitude of the second angular amount ( Fig, 5f is vertical straight with lower surface and the second angular amount can be less as the wall 607b is flexible ¶0151 and the Fig 5f and Fig. 5g). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so wherein a magnitude of the first angular amount is greater than a magnitude of the second angular amount as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144). Re Claim 26, Garben fails to disclose wherein a magnitude of the first angular amount is nominally twice the magnitude of the second angular amount. The instant disclosure describes the parameter of the magnitude of angular amount as being merely preferable (see ¶0129), and does not describe the magnitude of angular amount as contributing any unexpected results to the system. As such, parameters such as the magnitude of angular amount are considered to be matters of design choice, well within the skill of the ordinary artisan, obtained through routine experimentation in determining optimum results. Thus, it would have been obvious to one having ordinary skill in the art at the time the invention was made that the limitation of the magnitude of angular amount would be dependent on the actual application of the system and, thus would be a design choice based on the actual application. Re Claim 31, Garben fails to disclose wherein the filling surface and at least one first contact surface among the one or more first contact surfaces oppose each other for a first distance, and a second distance between the filling surface and the at least one first contact surface increases as at least part of the first distance is traversed away from the end of the filling surface, where the first opening is arranged. However, Sardari discloses a gas removal apparatus (Fig. 16b) and wherein the filling surface (607a) and at least one first contact surface ( 607b) among the one or more first contact surfaces oppose each other for a first distance (Fig, 5f), and a second distance between the filling surface and the at least one first contact surface increases as at least part of the first distance is traversed away from the end of the filling surface, where the first opening is arranged (Fig. 5g). Thus, it would have been prima facie obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modify filling surface Garben so that the filling surface and at least one first contact surface among the one or more first contact surfaces oppose each other for a first distance, and a second distance between the filling surface and the at least one first contact surface increases as at least part of the first distance is traversed away from the end of the filling surface, where the first opening is arranged as taught by Sardari for the purpose of controlling the level of the liquid as by controlling the pressure inside the chamber (Sardari, ¶0144).
