DETAILED ACTION
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 .
Claim Objections
Claims 15-17 are objected to because of the following informalities: Claim 16 is missing within the claim set filed on 05/23/2023. If there is no claim 16, it is recommended that claim numbering be corrected.
Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
Claims 13-20 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor, or for pre-AIA the applicant regards as the invention.
Regarding claim 13, lines 6 and 8, the phrase “vehicle near”, and “boom near”, it is unclear what is meant by “near” and how far away the vehicle or boom need to be in order to satisfy the limitation of being “near” the railroad track requiring welding.
For the purposes of substantive examination, the word “near” is construed as the vehicle and boom are located in a position where they are still capable of allowing the welding unit to be placed over the rails that need to be worked.
Claims 14-20 are also rejected based on their dependence to Claim 13.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1, 3-4, 7, 12-13, 15, and 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Coomer (US 20050067381 A1) in view of Barger et al. (US 3482076 A, hereinafter Barger).
Regarding claim 1, Coomer discloses a deployable mobile welding system (Abstract, “a mobile weld delivery unit”) comprising:
a vehicle (Para. 0078, “The preferred weld delivery unit 100, shown in FIG. 25, will essentially be a welding skid 506 mounted in a transport vehicle such as a truck 104.”);
a slidable base unit disposed on a track within the vehicle (Para. 0095, “The robot 500 welding range from the weld delivery unit is only limited by the length of the umbilical 510. Thus the robot 500 can be readily and quickly stored or deployed for use.”, where Fig. 24 shows that the welding robot 500 includes a railing system that allows it to extend out of the vehicle and where the extension is limited by the umbilical cord 510, where Fig. 22 shows that the railing system to allowing the welding robot to extend is located within the vehicle);
a mounting platform attached to an end of an extension from the slidable base unit (Para. 0094, “It will be seen that the robot, as is known to one in the robotics art, has a base 430 mounted to rotational bearing 432”, and Fig. 22, where the mounting platform of the robot extends from the structure holding onto the rails within the vehicle 426); and
a welding unit extending from the mounting platform (Para. 0094, “base 430 having a series of joints 438 and, for this application, terminates in welder head 440.”).
Coomer does not disclose:
a boom extending from the slidable base unit.
However, Barger discloses, in the similar field of mobile welding systems (Section 1, lines 55-57, “a base assembly traveling on a set of tracks for the purpose of alignment with respect to the plates to be welded.”), where a boom can extend out from a slidable base unit (Claim 5, “a side beam car slideably mounted on said horizontal ram so as to permit relative movement therebetween; an actuating means for reciprocally moving said side beam car with respect to said horizontal ram”; and Claim 1, “a traveling base assembly; a vertical mast mounted on said base assembly; a vertically adjustable ram supporting means mounted on said vertical mast; a horizontal ram supported by said ram supporting means; a welding means reciprocally mounted on said horizontal ram”, where the traveling base is the slidable base unit, where the ram is the boom, and where the welding means or welding robot is mounted on the ram through the side beam car). It would have been obvious for one of ordinary skill in the art before the effective filling date of the claimed invention to have modified the slidable base unit and robot in Coomer to include a boom located in between the two structures as taught by Barger.
One of ordinary skill in the art would have been motivated to make this modification in order to gain the advantage of being able to increase the range of motion for the robot welder, where the boom can be extended to increase the distance that the robot can be placed from the vehicle, as stated by Barger, Section 5, lines 2-8, “The motor 28 is actuated to raise or lower the apron assembly 22 on tracks 52 to the particular height at which the welding seam is to be initiated whereupon the horizontal ram 24 is moved longitudinally with respect to the supporting apron assembly 22 until the forward end thereof is adjacent the vertical welding groove between the work pieces.”, where the boom or ram allows for the welding device to reach the correct positions for welding.
Regarding claim 3, modified Coomer teaches the apparatus according to claim 1, as set forth above.
Modified Coomer does not disclose:

However, Barger discloses where the slidable base unit includes rollers for rolling the slidable base along a track (Section 2, lines 57-59, “A base 12, having wheels 14, 14' cooperating with the tracks 16, 16' is propelled by a motor 17 of any well-known type.”). It would have been obvious for one of ordinary skill in the art before the effective filling date of the claimed invention to have modified the slidable base unit along a track within a vehicle in modified Coomer to include rollers on the base unit for sliding as taught by Barger.
One of ordinary skill in the art would have been motivated to make this modification in order to gain the advantage of being able to use a structure that can be moved along a track, where rollers are shown as one such structure that allows for movement along a track, as stated by Barger, Section 2, lines 57-59, “A base 12, having wheels 14, 14' cooperating with the tracks 16, 16' is propelled by a motor 17 of any well-known type.”.
Regarding claim 4, modified Coomer teaches the apparatus according to claim 1, as set forth above, discloses wherein the boom is extendable (Teaching from Barger, Section 5, lines 2-8, “The motor 28 is actuated to raise or lower the apron assembly 22 on tracks 52 to the particular height at which the welding seam is to be initiated whereupon the horizontal ram 24 is moved longitudinally with respect to the supporting apron assembly 22 until the forward end thereof is adjacent the vertical welding groove between the work pieces.”).

Regarding claim 12, modified Coomer teaches the apparatus according to claim 1, as set forth above, discloses wherein the welding unit comprises a cold metal transfer (CMT) welding head, a laser hot wire welding head, a laser powder welding head, or a metal inert gas welding head (Coomer, Claim 2, “The on site railroad rail welding repair apparatus of claim 1 wherein the arc welder is a gas shielded arc welder, or electroslag arc welder, or a hidden arc welder, or an inert gas arc welder.”, where the inert gas arc welding to used for metals, Claim 1, “an arc welder that fills the void with appropriate molten metal and causes the molten metal and the rail at the rail-void interface to bond.”).
Regarding claim 13, Coomer discloses a method of using a deployable mobile welding system (Para. 0072, “The welding operation will be accomplished by the following steps: placing a ceramic base mold below the rail base and then commencing the welding operation whereby approximately a 1 to 3 inch void between the rail walls 22 and 24 is filled by welding material.”), the method comprising the steps of:
providing a vehicle (Para. 0078, “The preferred weld delivery unit 100, shown in FIG. 25, will essentially be a welding skid 506 mounted in a transport vehicle such as a truck 104.”) comprising a slidable base unit disposed on a track within the vehicle (Para. 0095, “The robot 500 welding range from the weld delivery unit is only limited by the length of the umbilical 510. Thus the robot 500 can be readily and quickly stored or deployed for use.”, where Fig. 24 shows that the welding robot 500 includes a railing system that allows it to extend out of the vehicle and where the extension is limited by the umbilical cord 510, where Fig. 22 shows that the railing system to allowing the welding robot to extend is located within the vehicle),

placing the vehicle near a railroad track requiring welding (Para. 0078, “The preferred weld delivery unit 100, shown in FIG. 25, will essentially be a welding skid 506 mounted in a transport vehicle such as a truck 104. Equipped with a boom not shown, the weld delivery unit 100 can deploy the rail repair alignment device 201, the weld containment device 290 and the portable welding robot 500 which together are called the robotic welding head 508.”, where the transport vehicle would first need to be placed near the rail that needs repair);

Equipped with a boom not shown, the weld delivery unit 100 can deploy the rail repair alignment device 201, the weld containment device 290 and the portable welding robot 500 which together are called the robotic welding head 508.”, where after the vehicle is positioned near the rail that needs repair, the weld delivery unit is deployed through sliding along a track and the welding robot with an extension of the robotic arms would be extended out of the vehicle, where the track is shown in Fig. 22);
positioning the extension near the railroad track requiring welding (Para. 0094, “While the robot 408 is typical in that it operates in three dimensions using controller 410, the ability to remotely place the robot at a specific weld location provides a major departure from known art. This portability provides considerable advantages when used in the field as a robotic welding head 508. Instead of a work piece being brought to and located proximate a fixed robot, this apparatus brings the welder to the work piece-in this case railroad rail 10-and uses interfacing with rail 10 to automatically weld the slot 28 in rail 10.”, where the entire robotic welding system is brought close to the railroad track that requires repair, where the extension connected to the robotic head that has the welder would also be close to the railroad track because the robotic head is directly connected to the extension; therefore if the head is close to the railroad track, then the extension must also be close; where in the teaching from Barger below, the extension can be an extendable boom, and the boom would then be close to the railroad track); and
manipulating the welding unit to weld the railroad track (Para. 0094, “Instead of a work piece being brought to and located proximate a fixed robot, this apparatus brings the welder to the work piece-in this case railroad rail 10-and uses interfacing with rail 10 to automatically weld the slot 28 in rail 10.”, where the robotic welding head is brought close to the railroad track that needs repair and starts welding to repair the track).
Coomer does not disclose:

It would have been obvious for one of ordinary skill in the art before the effective filling date of the claimed invention to have modified the slidable base unit and robot in Coomer to include a boom located in between the two structures as taught by Barger.
One of ordinary skill in the art would have been motivated to make this modification in order to gain the advantage of being able to increase the range of motion for the robot welder, where the boom can be extended to increase the distance that the robot can be placed from the vehicle, as stated by Barger, Section 5, lines 2-8, “The motor 28 is actuated to raise or lower the apron assembly 22 on tracks 52 to the particular height at which the welding seam is to be initiated whereupon the horizontal ram 24 is moved longitudinally with respect to the supporting apron assembly 22 until the forward end thereof is adjacent the vertical welding groove between the work pieces.”, where the boom or ram allows for the welding device to reach the correct positions for welding.

further comprising the step of: extending the boom from the slidable base unit when positioning the boom near the railroad track requiring welding (Coomer, Para. 0094, “While the robot 408 is typical in that it operates in three dimensions using controller 410, the ability to remotely place the robot at a specific weld location provides a major departure from known art. This portability provides considerable advantages when used in the field as a robotic welding head 508. Instead of a work piece being brought to and located proximate a fixed robot, this apparatus brings the welder to the work piece-in this case railroad rail 10-and uses interfacing with rail 10 to automatically weld the slot 28 in rail 10.”, where the entire robotic welding system is brought close to the railroad track that requires repair, where the extension connected to the robotic head that has the welder would also be close to the railroad track because the robotic head is directly connected to the extension; therefore if the head is close to the railroad track, then the extension must also be close; where in the teaching from Barger below, the extension can be an extendable boom, and the boom would then be close to the railroad track).

Regarding claim 18, modified Coomer teaches the method according to claim 13, as set forth above, discloses wherein the welding unit comprises a rotatable mounting base extending from a surface of the mounting platform (Coomer, Para. 0094, “robot 500 has articulated arm 436 which is articulated to bearing 432 and base 430 having a series of joints 438 and, for this application, terminates in welder head 440.”, where the mounting platform or base 430 includes a bearing 432 that rotates the welding unit 440),
further comprising the step of: rotating the welding unit when manipulating the welding unit to weld the railroad track (Coomer, Para. 0094, “rotational bearing 432 which enables the robot to rotate around a rotational axis 434”, and Para. 0073, “Using a continuous precisely controlled welding cycle will move the welding element back and forth across the void resulting in the filling of the void with metal material having mechanical properties commensurate with that of the metal in the rail itself.”, where the robot is moved back and forth during the weld and is moved toward the railroad that needs repair, where this movement would require rotating the welding unit).
Modified Coomer does not disclose:
where the welding unit is disposed on a bottom surface of the mounting platform.
However, Tamura discloses, in the similar field of movable welding apparatuses (Page 2, Para. 3, “welding apparatus 1 shown in FIG. 1 includes a base 2, a support 3, a laterally stretchable body 4, a longitudinally stretchable body 5, and a robot 6.”), where the welding unit extends from a bottom surface and is disposed on the bottom surface of the mounting platform (Page 6, Para. 1, “The robot 6 is attached to the lower end of the longitudinally extending body 5.”, and where the longitudinally extending body 5 or mounting platform is connected to the boom, Page 6, Para. 1, “The vertical stretchable body 5 is attached to the distal end of the horizontal stretchable body 4”, where when the longitudinally extending body is not extended, the welding robot would be disposed on the bottom surface of the mounting platform). It would have been obvious for one of ordinary skill in the art before the effective filling date of the claimed invention to have modified the mounting platform with joints connecting to a welding unit in modified Coomer to include a direct connection between the mounting platform and the welding unit as taught by Tamura.
One of ordinary skill in the art would have been motivated to make this modification in order to gain the advantage of being able to reduce the complexity of the attachments between the mounting platform and the welding unit, where a singular transverse and longitudinal connection can still provide the welding unit with repositioning abilities, as stated by Tamura, Abstract, “The post is made movable according to the movement of the running body, and is equipped with two or more longitudinal expansion bodies capable of expanding in the longitudinal direction so that the welding apparatus can be stepwise extended or stepwise shrunken to the original position before the extension. The welding apparatus may comprise both a transverse expansion body and a longitudinal expansion body.”.
Regarding claim 19, modified Coomer teaches the method according to claim 13, as set forth above, discloses wherein the welding unit further comprises a first rotatable arm extending from a rotatable mounting base (Coomer, Para. 0094, “robot 500 has articulated arm 436 which is articulated to bearing 432 and base 430 having a series of joints 438 and, for this application, terminates in welder head 440.”, where the mounting platform or base 430 includes a bearing 432 that rotates the welding unit 440, where after the bearing 432 or the rotatable mounting base is an articulated arm 436 that is the first rotatable arm that extends from the rotatable mounting base), and
further comprises a second rotatable arm extending from an end of the first rotatable arm (Coomer, Para. 0094, “robot 500 has articulated arm 436 which is articulated to bearing 432 and base 430 having a series of joints 438 and, for this application, terminates in welder head 440.”, where the series of joints 438 are the second rotatable arm connected after the first rotatable arm 436, where the features are shown in modified Fig. 22), and
further wherein a rotatable welding head extends from an end of the second rotatable arm (Coomer, Para. 0094, “robot 500 has articulated arm 436 which is articulated to bearing 432 and base 430 having a series of joints 438 and, for this application, terminates in welder head 440.”, where after the series of joints 438 that are the second rotatable arm, the system includes a welding head 440 that is shown in modified Fig. 22 to be rotatable).
Modified Coomer does not disclose:
wherein the rotatable mounting base is disposed on a bottom surface of the mounting platform.
However, Tamura discloses, in the similar field of movable welding apparatuses (Page 2, Para. 3, “welding apparatus 1 shown in FIG. 1 includes a base 2, a support 3, a laterally stretchable body 4, a longitudinally stretchable body 5, and a robot 6.”), where the welding unit extends from a bottom surface and is disposed on the bottom surface of the mounting platform (Page 6, Para. 1, “The robot 6 is attached to the lower end of the longitudinally extending body 5.”, and where the longitudinally extending body 5 or mounting platform is connected to the boom, Page 6, Para. 1, “The vertical stretchable body 5 is attached to the distal end of the horizontal stretchable body 4”, where when the longitudinally extending body is not extended, the welding robot would be disposed on the bottom surface of the mounting platform). It would have been obvious for one of ordinary skill in the art before the effective filling date of the claimed invention to have modified the mounting platform with joints connecting to a welding unit in modified Coomer to include a direct connection between the mounting platform and the welding unit as taught by Tamura; where the robot head connected to a bearing connected to the mounting platform in Coomer would have the bearing and robot be placed at the bottom surface of the mounting platform from the teaching of Tamura.
One of ordinary skill in the art would have been motivated to make this modification in order to gain the advantage of being able to reduce the complexity of the attachments between the mounting platform and the welding unit, where a singular transverse and longitudinal connection can still provide the welding unit with repositioning abilities, as stated by Tamura, Abstract, “The post is made movable according to the movement of the running body, and is equipped with two or more longitudinal expansion bodies capable of expanding in the longitudinal direction so that the welding apparatus can be stepwise extended or stepwise shrunken to the original position before the extension. The welding apparatus may comprise both a transverse expansion body and a longitudinal expansion body.”.
