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) 1-2, 4, 8, 14-15, 18-19, and 21-23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wakalopulos (US 6140657 A) in view of BILSTAD (US 20060110282 A1) and TAKEMOTO (US 20180161554 A1).
Regarding claim 1, Wakalopulos (US 6140657 A) teaches a plasma welding apparatus (Figure 2), comprising:
an operation chamber (chamber 35);
a plasma generator having at least one plasma head disposed within the operation chamber and in proximity to an end contact surface of a first profile within the operation chamber and an end contact surface of a second profile within the operation chamber (Figure 2 Column 3 Line 66 – Column 4 Line 4, beam 15 is directed toward tubing 29 and 31 for an operation which involves a fill operation of cutting the bags for filling and then resealing the tubes together; Figures 1-2 Column 4 Lines 18-22, chamber 35 is equipped with a beam tube with a window 13 for generating a plasma cloud in the volume surrounding the surfaces to be sterilized at target zone 34; Figure 1, electron beam tube 11 and gas nozzle are located in proximity to the target zone), wherein each of the first profile and the second profile comprises a tube having a lumen (Figure 1, tubing 29 and 31 each have an internal lumen for carrying fluids),
wherein the operation chamber forms a substantially sealed environment (Column 2 Lines 23-27, sterilization chamber; Column 4 Lines 27-29, ionization radiation is kept inside of the sterilization chamber which indicates that the operation chamber is sealed), and wherein the operation chamber confines the plasma treatment within the substantially sealed environment (Column 4 Lines 27-29, ionization radiation is kept inside of the sterilization chamber which indicates that the operation chamber is sealed)1, wherein the mechanical motion module is configured to manipulate the one or more lumens of the first profile and the second profile prior to plasma welding, so that the first profile and the second profile can remain open or closed during the plasma treatment and/or joining the first profile and the second profile (Figure 2 Column 3 Line 66 – Column 4 Line 4, manipulating the lumen of the first and second profile prior to connecting and resealing by cutting the tubing from each bag such that the tubing can be connected for the filling operation and then resealed later).
Wakalopulos fails to explicitly teach:
wherein the plasma head is configured to apply a plasma treatment to the end contact surfaces of the first profile and the second profile to directly join a thermoset elastomer of the first or second profile to the other profile, wherein at least one of the first profile and the second profile are formed from the thermoset elastomer comprising a silicone elastomer, a diene elastomer, a butyl rubber, a natural rubber, an ethylene propylene diene monomer rubber, an isoprene rubber, a nitrile rubber, a styrene butadiene rubber, a blend, or combination thereof; and
a mechanical motion module configured to axially align and bring into contact the end contact surfaces of the first profile and the second profile by rotary motion of at least one of the end contact surface first profile or the end contact surface of second profile, wherein the tube and lumen of each of the first profile and second profile define a terminal end in an axial direction, wherein the end contact surfaces of the first and second profiles are located at the terminal ends of the first and second profiles,
BILSTAD (US 20060110282 A1) teaches a method for manipulating pre-sterilized components in an active sterile field, wherein:
wherein each of the first profile and the second profile comprises a tube having a lumen (Paragraph 38, ends of components 10 and 12 are cut off such as to reveal open ends while still within the field)
wherein the plasma head is configured to apply a plasma treatment to the end contact surfaces of the first profile and the second profile (Figure 3D Paragraph 39, plasma atmosphere is created to achieve a sterile field; Paragraph 40, connection of the open ends together is accomplished while the contacting ends are exposed within the field; Paragraph 45, permeant seal between the contacting ends is accomplished while the contacting ends are exposed within the field),
a mechanical motion module configured to axially align and bring into contact the end contact surfaces of the first profile and the second profile by rotary motion of at least one of the end contact surface first profile or the end contact surface of second profile (Paragraph 40, mechanism uses a pair of automated clamps which engage a portion of components 10 and 12 just behind the ends such as to actuate in the direction of the arrows and are capable of rotational movement to maintain the alignment ends of the components with one another; Figures 8A-8D, tubes are sealed together by being in contact with each other), wherein the tube and lumen of each of the first profile and second profile define a terminal end in an axial direction, wherein the end contact surfaces of the first and second profiles are located at the terminal ends of the first and second profiles (Paragraph 30, components have sealed ends which by connecting together which allow for a fluid pathway to be created at the time of joining between the two components; Figures 3A-3D Paragraph 38, the lumen of the first and second components extend in an axial direction and the location where the components are connected are each at a terminal end of the components), wherein the mechanical motion module is configured to manipulate the one or more lumens of the first profile and the second profile prior to plasma welding, so that the first profile and the second profile can remain open or closed during the plasma treatment and/or joining the first profile and the second profile (Paragraph 38, exposing the lumens of the first and second components by cutting them off by means of a mechanical blade such as to keep them open during connection).
It would have thus been obvious to someone of ordinary skill in the art before the filing date of the claimed invention to have modified Wakalopulos with BILSTAD and included a mechanical motion module for aligning ends of the first and second profile together. This would have been done to help maintain the alignment of ends of the tubes with one another during the processing (BILSTAD Paragraph 40).

It would have further been obvious to someone of ordinary skill in the art before the filing date of the claimed invention to have modified Wakalopulos with TAKEMOTO_2 and have the first and second tubes be made at least partially of acrylic resin. This would have been done as TAKEMOTO teaches that the degree of freedom of selecting a tube material is large (TAKEMOTO Paragraph 12) wherein there is no particular limitation for the materials of the first tube and the second tube as long as they are synthetic resins (TAKEMOTO Paragraph 45) and TAKEMOTO_2 teaches that synthetic resins used in plasma surface activation process includes silicone resin and acrylic resin wherein acrylic resin is particularly beneficial when light transmittance is desired (TAKEMOTO_2 Paragraph 57).
Claim(s) 7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wakalopulos (US 6140657 A) in view of BILSTAD (US 20060110282 A1) and TAKEMOTO (US 20180161554 A1) as applied to claim 1 above, and further in view of Therond (US 20030102293 A1).

the fluorine (Paragraph 4, gas includes fluorine) containing gas comprises sulfur hexafluoride (SF6), trifluoromethane (CHF3), tetrafluoromethane (CF4) (Paragraph 4, CF4), octafluorocyclobutane (C4F8), or a combination thereof.
It would have thus been obvious to someone of ordinary skill in the art before the filing date of the claimed invention to have modified Wakalopulos with LEE and use CF4 as the gas. This gas is known in the art in plasma processing and one of ordinary skill in the art would use such air as an alternative to dry air or clean dry air, or when dry air or clean dry air is not available.
The Office further notes that the use of sulfur hexafluoride and trifluoromethane are known in the art to be used as the gas to be ionized to generate plasma for plasma processing as evidenced by Mahoney (US 5521351 A).

at least one of the plurality of plasma heads is configured to sterilize the environment within the operation chamber (Paragraphs 105-106, combination of operations includes the plasma-assisted processes of welding and sterilizing).
It would have thus been obvious to someone of ordinary skill in the art before the filing date of the claimed invention to have modified Wakalopulos with Dougherty and have at least one of the plasma heads sterilize the environment. This would have been done to perform detoxification and cleaning the area which is a beneficial use of plasma torches known in the art as evidenced by PATRIGI (US 20140263202 A1).
