Office Action

§103
CTNF 18/502,693 CTNF 86565 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-fti AIA The present application is being examined under the pre-AIA first to invent provisions. Double Patenting 08-33 AIA The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg , 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman , 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi , 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum , 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel , 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington , 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA/25, or PTO/AIA/26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/process/file/efs/guidance/eTD-info-I.jsp. Claims 11-18 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-7 of U.S. Patent No. 10888947. Application 18/502693 Patent 10888947 11. A welding system, comprising: 1. A welding system, comprising: a visual acquisition system comprising an imaging device and configured to acquire a visual representation of a weld part having a weld joint and to convert the visual representation into data representative of weld part features ; and a visual acquisition system comprising an imaging device configured to acquire a visual representation of a workpiece and to convert the visual representation into data representative of the visual representation ; and a part recognition component comprising processing circuitry configured to: a workpiece recognition component comprising processing circuitry configured to: receive the data; Not explicitly recited identify one or more features of the weld part in response to receipt of the received data ; identify one or more characteristic geometric features of the workpiece based on the data; compare the received data to stored data of a plurality of weld parts stored in a weld part database to match one or more identified features to a known weld part of the plurality of weld parts stored in the weld part database; compare the one or more characteristic geometric features of the workpiece to a plurality of known workpieces stored in a first database to match the workpiece to a matching known workpiece of the plurality of known workpieces stored in the first database; identify weld settings stored in a weld parameter database associated with the matching known weld part of the plurality of weld parts stored in the weld part database; and identify weld settings stored in a second database associated with the two or more of the plurality of known workpieces stored in the first database; send the weld settings to a welding power supply to be implemented during a weld operation. send the weld paramete r set to a welding power supply. While the ‘947 Patent does not explicitly recite that the processing circuitry is configured to receive the data from the visual acquisition system, such limitation is either inherent or implied since the processing circuity is claimed as being configured to identify one or more geometric features of the workpiece based on the data. In order for this limitation to be met the processing circuitry must receive the data. That is, in order for the processing circuitry to perform the function of identifying a geometric feature of the workpiece based on the data from the visual acquisition system (i.e., imaging device), the processing circuitry must receive the data by some means (e.g., electronically receiving the data; the data being input into the circuitry manually by a user, etc.). Furthermore, while the ‘947 Patent does not explicitly disclose the workpiece (weld part) “having a weld joint” such limitation does not impart a meaningful difference to the claimed welding system as such limitation pertains to the material or article worked upon by the claimed structure which does not limit nor define the structure being claimed. Although the claims at issue are not identical, they are not patentably distinct from each other because claim 1 of the ‘693 application is anticipated by claim 1 of the ‘947 Patent. Application 18/502693 Patent 10888947 12. The welding system of claim 11, comprising the welding power supply configured to communicate with the part recognition component to receive the weld settings and to alter setup of the welding power supply to implement the weld settings prior to initiation of a weld operation. 2. The welding system of claim 1, comprising the welding power supply configured to communicate with the workpiece recognition component to receive the weld parameter set and to alter setup of the welding power supply to implement the weld parameter set prior to initiation of a weld operation. 18. The welding system of claim 11, wherein the visual acquisition system is disposed in or on a welding helmet configured to be worn by a welding operator. 3. The welding system of claim 1, wherein the visual acquisition system is disposed in or on a welding helmet configured to be worn by a welding operator. 14. The welding system of claim 11, wherein the imaging device comprises a digital camera configured to capture the visual representation and to convert the visual representation to the data. 4. The welding system of claim 1, wherein the imaging device comprises a digital camera configured to capture the visual representation and to convert the visual representation to the data. 15. The welding system of claim 11, wherein the visual acquisition system comprises a power source and a power regulator configured to cooperate to supply power to the imaging device. 5. The welding system of claim 1, wherein the visual acquisition system comprises a power source and a power regulator configured to cooperate to supply power to the imaging device. 17. The welding system of claim 11, wherein the weld settings include selection of an appropriate welding process or regime. 8. The welding system of claim 1, wherein the weld settings include selection of an appropriate welding process or regime. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 12, 14, 15, 17 and 18 of the ‘693 application are anticipated by claims 2-5 and 6 of the ‘947 Patent. Claim Rejections - 35 USC § 103 07-20-fti The following is a quotation of pre-AIA 35 U.S.C. 103(a) which forms the basis for all obviousness rejections set forth in this Office action: (a) A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negated by the manner in which the invention was made. 07-23-fti The factual inquiries for establishing a background for determining obviousness under pre-AIA 35 U.S.C. 103(a) 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. 07-21-fti Claim 11-14, 16 and 17 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Conrardy (US 2011/0117527) in view of Endo (US 2004/0050905) . With respect to the limitations of claim 11, Conrardy teaches a welding system (Figs 1-5, title, abstract), comprising: a visual acquisition system comprising an imaging device (0027, data capturing component 100 which includes at least one digital camera or imaging device) and configured to acquire a visual representation of a weld part having a weld joint (0005, the “data capturing component…for capturing images of the target”), and to convert the visual representation into data representative of weld part features (the image of the target captured by the imaging device/camera) (See also Abstract; the data generating component operates “in real time and derives data from an actual manually-executed weld”); and a part recognition component (0072, data processing and visualization component 200; data capturing component 100 is in electronic communication with data processing component 200 which is in electronic communication with data visualization component 300. 200 and 300 may reside within or on the same computer based system) comprising processing circuitry (0005, “The data processing and visualization component further includes: at least one computer for receiving and analyzing information captured by the data capturing component, wherein the at least one computer is running software that includes a training regimen module, wherein the training regimen module includes a variety of weld types and a series of acceptable welding process parameters associated with creating each weld type”) configured to: receive the data (Figure 5; image processing step 112; 0029, “The data processing and visualization components of the present invention (200 and 300 respectively) typically include at least one computer for receiving and analyzing information captured by the data capturing component 100.”); identify one or more features of the weld part in response to receipt of the received data (0028, “The input aspect of image processing step 112 includes analyzing individual images of the target looking for a match to a known "trained" object (i.e., the calibrated target).”); compare the received data to stored data of a plurality of weld parts stored in a weld part database to match one or more identified features to a known weld part of the plurality of weld parts stored in the weld part database (0028, “The input aspect of image processing step 112 includes analyzing individual images of the target looking for a match to a known "trained" object (i.e., the calibrated target). Upon recognition of a known object, position and orientation are calculated relative to the "trained" object position and orientation.”); identify weld settings stored in a weld parameter database associated with the matching known weld part of the plurality of weld parts stored in the weld part database ( 0028, “The input aspect of image processing step 112 includes analyzing individual images of the target looking for a match to a known "trained" object (i.e., the calibrated target). Upon recognition of a known object, position and orientation are calculated relative to the "trained" object position and orientation….The output aspect of i mage processing step 112 includes creation of a text file that includes x-axis, y-axis, and z-axis positional data and roll, pitch, and yaw orientation data, as well as time stamps and software flags…The input aspect of data processing step 212 includes raw positional and orientation data typically requested at about 15-20 times per second, while the output aspect includes transforming this raw data into useful welding parameters with algorithms specific to a selected process and joint type. The input aspect of data storage step 214 includes storing welding trial data as a *.dat file, while the output aspect includes saving the data for review and tracking, saving the date for review on a monitor at a later time, and/or reviewing the progress of the student at a later time. Student progress may include total practice time, total arc time, total arc starts, and individual parameter-specific performance over time. The input aspect of data display step 310 includes welding trial data that further includes work angle, travel angle, tip-to-work distance/torch offset, travel speed, torch proximity to axis, voltage, current, wire-feed speed, while the output aspect involves data that may viewed on a monitor, in-helmet display, heads-up display, or combinations thereof, wherein parameters are plotted on a time-based axis and compared to upper and lower thresholds (see FIG. 6) or preferred variations, such as those trained by recording the motions of an expert welder. Current and voltage may be measured in conjunction with travel speed to determine heat input and the welding process parameters may be used to estimate arc length. Position data may be transformed into weld start position, weld stop position, weld length, weld sequence, welding progression, or combinations thereof and current and voltage may be measured in conjunction with travel speed to determine heat input.”). Conrardy inherently discloses a welding power supply, but, Conrardy does not explicitly discloses sending the weld settings to a welding power supply to be implemented during a weld operation. However, Endo discloses sending (Abstract; machining apparatus, “which is applicable to soldering or the like”) (Figure 2) for processing circuitry (controller 8) the weld settings to a welding power supply (Figs 1, 2, power supply 101, 0047) to be implemented during a weld operation (0057, “controller 8 reads a machining condition corresponding to a current machining position from machining condition storage unit 104 and supplies the machining condition to light-energy power supply 101 in order to machine workpiece 13. Simultaneously, camera 9 captures a machining status, and thus, image recognition device 10 recognizes a machining result. Comparator 102 compares the machining result recognized with information about proper machining that is stored in machining status storage unit 103, and then, machining condition storage unit 104 receives feedback from comparator 102. The machining condition is corrected based on the information fed back and is supplied to light-energy power supply 101 for soldering or the like.”) is known in the art. Therefore, it would have been obvious to someone with ordinary skill in the art at the time the invention was made to modify Conrardy with Endo, by adding to the processing circuitry, with respect to the weld settings, of Conrardy, with the teachings of Endo, in order to provide feedback control to the power supply to ensure proper welding of the workpiece. With respect to the limitations of claims 12, 13, 14, 16 and 17, Conrardy in view of Endo discloses comprising the welding power supply (Endo, power supply 101) configured to communicate with the part recognition component (Endo, image recondition device 10, 0091) to receive the weld settings and to alter setup of the welding power supply to implement the weld settings prior to initiation of a weld operation (Endo, 0057, “controller 8 reads a machining condition corresponding to a current machining position from machining condition storage unit 104 and supplies the machining condition to light-energy power supply 101 in order to machine workpiece 13. Simultaneously, camera 9 captures a machining status, and thus, image recognition device 10 recognizes a machining result. Comparator 102 compares the machining result recognized with information about proper machining that is stored in machining status storage unit 103, and then, machining condition storage unit 104 receives feedback from comparator 102. The machining condition is corrected based on the information fed back and is supplied to light-energy power supply 101 for soldering or the like.”); the weld settings comprise a set of welding parameters (Conrardy, 0028, “The input aspect of data display step 310 includes welding trial data that further includes work angle, travel angle, tip-to-work distance/torch offset, travel speed, torch proximity to axis, voltage, current, wire-feed speed, while the output aspect involves data that may viewed on a monitor, in-helmet display, heads-up display, or combinations thereof, wherein parameters are plotted on a time-based axis and compared to upper and lower thresholds (see FIG. 6) or preferred variations, such as those trained by recording the motions of an expert welder. Current and voltage may be measured in conjunction with travel speed to determine heat input and the welding process parameters may be used to estimate arc length. Position data may be transformed into weld start position, weld stop position, weld length, weld sequence, welding progression, or combinations thereof and current and voltage may be measured in conjunction with travel speed to determine heat input.), the welding power supply (Endo, power supply 101) configured to alter setup of the welding power supply to implement the weld settings prior to initiation of a weld operation (Endo, 0057, “controller 8 reads a machining condition corresponding to a current machining position from machining condition storage unit 104 and supplies the machining condition to light-energy power supply 101 in order to machine workpiece 13.

The machining condition is corrected based on the information fed back and is supplied to light-energy power supply 101 for soldering or the like.”); the imaging device comprises a digital camera (Conrardy, 0027, data capturing component 100 which includes at least one digital camera or imaging device) configured to capture the visual representation and to convert the visual representation to the data (Conrardy, the image of the target captured by the imaging device/camera) (Abstract; 0023, the data generating component operates “in real time and derives data from an actual manually-executed weld”); the part recognition component (Conrardy, 200/300m, 0072) is configured to distinguish between multiple parts (individual welding targets) having respective associated weld settings based on one or more visual representations of the multiple parts and respective characteristic geometric features of the multiple parts (0005, “data processing and visualization component further includes: at least one computer for receiving and analyzing information captured by the data capturing component, wherein the at least one computer is running software that includes a training regimen module, wherein the training regimen module includes a variety of weld types and a series of acceptable welding process parameters associated with creating each weld type; an object recognition module for recognizing the target; and a data processing module for comparing the information in the training regimen module to the information processed by the object recognition module; and at least one display device in electrical communication with the at least one computer for allowing the trainee to visualize the processed data in real time, wherein the visualized data is operative to provide the trainee with useful feedback regarding the characteristics and quality of the weld.”) (0028, “The input aspect of image processing step 112 includes analyzing individual images of the target looking for a match to a known "trained" object (i.e., the calibrated target). Upon recognition of a known object, position and orientation are calculated relative to the "trained" object position and orientation….The output aspect of image processing step 112 includes creation of a text file that includes x-axis, y-axis, and z-axis positional data and roll, pitch, and yaw orientation data, as well as time stamps and software flags…The input aspect of data processing step 212 includes raw positional and orientation data typically requested at about 15-20 times per second, while the output aspect includes transforming this raw data into useful welding parameters with algorithms specific to a selected process and joint type.

Position data may be transformed into weld start position, weld stop position, weld length, weld sequence, welding progression, or combinations thereof and current and voltage may be measured in conjunction with travel speed to determine heat input.”); the weld settings include selection of an appropriate welding process or regime (Conrardy; as set forth in the rejection of claim 1 above) . 07-21-fti Claim s 15 and 18 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Conrardy (US 2011/0117527) in view of Endo (US 2004/0050905) as applied to claim 11, further in view of Becker (US 2009/0231423) . With respect to the limitations of claims 15 and 18, Conrardy teaches a welding helmet configured to be worn by a welding operator (Conrardy; para. 0023 and 0028) and that the visual acquisition system/imaging device of Conrardy inherently possesses a power source in order to function as intended. Conrardy in view of Endo discloses the claimed invention except for explicitly showing the visual acquisition system comprises a power source and a power regulator configured to cooperate to supply power to the imaging device; the visual acquisition system is disposed in or on a welding helmet configured to be worn by a welding operator. However, Becker discloses that it is known in the art of welding systems for recording welding operations (Figures 2-5, 0002) for a weld recording system (10) to be positioned in or on a welding helmet (12) worn by a welder (14, 0020). Becker, in Figures 2 and 3, discloses the recording system (10) including a camera assembly (36, 0022). Becker further discloses the welding recording system comprises a power source (56) and a power regulator (54) configured to cooperate to supply power to the imaging device (36) (0025, “A power supply 52 module provides power for the system, and may include a central power regulator 54 that receives power from a battery 56 and/or photovoltaic cells 40, a switch 58, and a low power detector 60. The power regulator 54 may consist of one or more DC-DC voltage regulators that convert battery power and/or light energy into power levels that the weld recording system 10 can use and supplies the camera assembly 36 with power”). Therefore, it would have been obvious to someone with ordinary skill in the art at the time the invention was made to modify Conrardy in view of Endo, with Becker by adding to the power supply of the visual acquisition system of Conrardy, with the teachings of Becker, in order to provide a power regulator that converts electrical power from the power supply into power levels that the visual acquisition system can use. Additionally, Becker discloses that it is known in the art of welding systems for recording welding operations (Figures 2-5, 0002) for a weld recording system (10) to be positioned in or on a welding helmet (12) worn by a welder (14, 0020). Becker, in Figures 2 and 3, discloses the recording system (10) including a camera assembly (36). Therefore, it would have been obvious to someone with ordinary skill in the art at the time the invention was made to modify Conrardy in view of Endo, with Becker by replacing the position of the imaging device of Conrardy, with the teachings of Becker, in order to provide an imaging device placement that encompasses the area where the welding operation is occurring and includes both the welding arc and a portion of the surrounding environment such that the field of view overlaps with the field of view of the welding operator (para. 0020).
