`
`The present application is being examined under the pre-AIA first to invent
`
`provisions.
`
`DETAILED ACTION
`
`Claim Rejections - 35 USC § 103
`
`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 negatived by the manner in which the invention was
`made.
`
`This application currently names joint inventors. In considering patentability of the
`
`claims under pre-AIA 35 U.S.C. 103(a), the examiner presumes that the subject matter
`
`of the various claims was commonly owned at the time any inventions covered therein
`
`were made absent any evidence to the contrary. Applicant is advised of the obligation
`
`under 37 CFR 1.56 to point out the inventor and invention dates of each claim that was
`
`not commonly owned at the time a later invention was made in order for the examiner to
`
`consider the applicability of pre-AIA 35 U.S.C. 103(0) and potential pre-AIA 35 U.S.C.
`
`102(e), (f) or (g) prior art under pre-AIA 35 U.S.C. 103(a).
`
`1.
`
`Claims 1,3-6,11-14,16-19,21-23 are rejected under pre-AIA 35 U.S.C. 103(a) as
`
`being unpatentable over Fujiwara et al (WO 2011/013321, counterparts EP 2402104
`
`and US 2012/0111842, supplied by applicants) in view of Narayanan et al (US
`
`2006/0070983) and Huismann et al (US 7,102,099). Reference for Fujiwara is to US
`
`counterpart for convenience.

`
`2.
`
`Regarding claim 1, Fujiwara discloses: A consumable electrode arc welding
`
`control method in which short-circuit welding is performed by alternating short-circuits
`
`and arcs while a welding wire is fed automatically(abstract), the method comprising:
`
`determining a basic wire feed speed, the basic wire feed speed being an average feed
`
`speed for a set welding current(para 13,40,44-determine;para 6,7,11,13,40,-welding
`
`wire feed rate suitable for a welding current is determined); and alternatively generating
`
`a short-circuit state and an arc state by feeding the welding wire at a predetermined
`
`frequency and a predetermined velocity amplitude with reference to the basic wire feed
`
`speed (abstract, para 34,39,46) (para 11-feeding rate according to a welding current,
`
`para 12,40-current is determined as ...feeding rate, 46,56,61,62 Fujiwara); and
`
`3.
`
`wherein an upper velocity amplitude of the wire feed speed above the
`
`basic wire feed speed is different from a lower velocity amplitude of the wire feed speed
`
`below the basic wire feed speed (para 40,46,56,63) (fig 1,5,para 60-64)(col 8-10
`
`Huismann,para 70,71 Narayanan).
`
`4.
`
`The claims at best differ in that there is a difference between velocity amplitudes
`
`above and below a basic wire feed speed which is an average feed speed for a set
`
`welding current. Average speed is taught in the reference as noted above.
`
`5.
`
`Huismann shows a welding wire feeding rate having a trapezoidal form (see
`
`Figure 8) having a combination of slowing, stopping, and retracting advancement of a
`
`feed wire as the welding operations are performed (see column 4, lines 6-22, col 8 line
`
`44-52), and Huismann also shows a welding operation that is timed to a peak time, a
`
`rising time, or a falling time, having the upper and lower limits as shown in Figure 8,
`
`
`
`Application/Control Number: 13/820,557
`
`Page 4
`
`Art Unit: 3742
`
`wherein the welding operation includes an arc state and a short circuit state that is
`
`repeated or cycled.
`
`6.
`
`See also Narayanan para 2, 71, fig 14. The references show changing and
`
`different waveforms for different directions and effects therefor.
`
`7.
`
`Huismann teaches advantages therefor in col 3 lines 50-65: Control of energy to
`
`the weld is affected using the output current or voltage magnitude, wave shape, time,
`
`etc. Thus, the transitions are caused to occur by controlling the wire movement, and
`
`current can be coordinated with, the transitions to reduce spatter, instability, or other
`
`undesirable features, by, for example, changing the current as the transition occurs, or
`
`in anticipation of the transition.
`
`The advantage is to reduce spatter, instability, or other undesirable features
`
`8.
`
`It would have been obvious for a person of ordinary skill in the art at the time of
`
`the invention to modify Fujiwara, if necessary, with the feeding wire rate having different
`
`trapezoidal or sinusoidal waveforms as known in Huismann and Narayanan that show
`
`the rate at which the feeding wire is advanced including a sloped rise and fall of the rate
`
`that is the representative of the feeding wire supplied by a motor to optimize, to improve
`
`control, spatter, defective beads and penetration.
`
`9.
`
`Regarding claim 14 at least, a different waveform to feed the wire between
`
`fonNard and backward directions is not critical or produces any new or unexpected
`
`results and is optimization although that recitation has been deleted from the claim. See
`
`Fujiwara para 12,46,62,72, Huismann column 4, lines 6-22, col 8 line 44-52, Narayanan
`
`para 2, 71, fig 14. Fujiwara teaches:
`
`
`
`Application/Control Number: 13/820,557
`
`Page 5
`
`Art Unit: 3742
`
`1.
`
`By virtue of the structure above, the apparatus employs a frequency and a
`
`velocity amplitude suitable for each welding current, providing optimum welding
`
`operation for each welding current (as will be described later). The structure minimizes
`
`the following problems: defective bead, increase in spatters, and lack of penetration.
`
`These problems can be as a result of instability of arc affected by increase in speed of
`
`welding and disturbances, such as change in wire extension and a gap in object 23 to
`
`be welded. Besides, the structure suppresses an adverse effect on production efficiency
`
`and working environment, providing an excellent arc welding apparatus.
`
`2.
`
`For claim 3: wherein the upper velocity amplitude is smaller than the lower
`
`velocity amplitude (fig 1,5).
`
`4.
`
`For claim 4: wherein a ratio of a short circuit period to an arc period is adjusted
`
`by setting the upper velocity amplitude to a product of the lower velocity amplitude and
`
`a ratio smaller than 1, thereby making the upper velocity amplitude smaller than the
`
`lower velocity amplitude (fig 1,5).
`
`5.
`
`For claim 5: wherein the ratio is determined based on at least one of a set
`
`current, a diameter of the welding wire, a type of the welding wire, an extension of the
`
`welding wire(abstract, and shielding gas(expedient in the art) to be used.
`
`6.
`
`For claims 6,11-13: wherein the welding wire is fed in such a manner that a
`
`waveform to feed the welding wire is changed either sinusoidal or trapezoidal with
`
`reference to the basic wire feed speed(para 63 Fujiwara). See the rejection of claim 1.

`
`Art Unit: 3742
`
`7.
`
`For claim 14: An arc welding control method, in which short-circuit states and arc
`
`states are alternately repeated, comprising: setting a set current before the arc welding
`
`(para 11-feeding rate according to a welding current, para 12,40-current is determined
`
`as ...feeding rate, 46,56,61,62 Fujiwara); and determining a basic wire feed speed, the
`
`basic wire feed speed being an average feed speed for the set current(para 13,40,44-
`
`determine;para 6,7,11,13,40,-welding wire feed rate suitable for a welding current is
`
`determined);
`
`8.
`
`feeding a welding wire at a predetermined frequency and a predetermined
`
`velocity amplitude with reference to the basic wire feed speed (abstract); wherein an
`
`upper waveform of the feed speed above the basic wire feed speed is different from a
`
`lower waveform of the feed speed below the basic wire feed speed(fig 5 Fujiwara). See
`
`rejection of claim 1.
`
`9.
`
`For claim 16: wherein an amplitude of the upper waveform is smaller than the an
`
`amplitude of the lower waveform(matter of design choice and optimization relative to
`
`suitable operating parameters, not critical or producing any new or unexpected results).
`
`11.
`
`For claim 17: wherein a ratio of a short circuit period to an arc period is adjusted
`
`by setting the amplitude of the upper waveform to a product of the amplitude of the
`
`lower waveform a ratio smaller than 1(fig 14 Narayanan, see claim 16).
`
`12.
`
`For claim 18: wherein the ratio is determined based on at least one of the set
`
`current, a diameter of the welding wire, a type of the welding wire, an extension of the
`
`welding wire, and shielding gas to be used(para 39 Fujiwara).

`
`For claim 19: wherein each shape of the upper waveform and the lower
`
`waveform is a part of a sinusoidal wave or trapezoidal wave(para 63,fig 5 Fujiwara, fig 8

`
`14.
`

`
`waveform is a part of a sinusoidal wave or trapezoidal wave(see claim 19).
`
`Response to Arguments
`
`18.
`
`Applicant's arguments filed 5/5/2016 have been fully considered but they are not
`
`persuasive.
`
`On page 6 of the remarks to page 9, applicant argues features not disclosed in
`
`the applied references:
`
`...determining a basic wire feed speed, the basic wire feed speed being an
`
`average feed speed for a set welding current...
`
`...feeding the welding wire at a predetermined frequency and a predetermined
`
`velocity amplitude with reference to the basic wire feed speed,
`
`wherein an upper velocity amplitude of the wire feed speed above the basic wire
`
`feed speed is different from a lower velocity amplitude of the wire feed speed below the
`
`basic wire feed speed.
`
`However the PTO disagrees.
`
`
`
`Application/Control Number: 13/820,557
`
`Page 8
`
`Art Unit: 3742
`
`The term “basic" means average. It includes average which can be zero. Para 75
`
`in the present publication says that basic comes from a table and in para 78 that it is
`
`determined by experimentation. The relationship between current and feed speed is
`
`taught in the references including Fujiwara as cited in the rejection. Basic wire feed
`
`speed is based on a set current in the art.
`
`Fujiwara teaches in the abstract and as cited above in the rejection:
`
`An arc welding method relates to consumable electrode arc welding in which a
`welding wire feeding rate suitable for a welding current is determined as an average
`feeding rate, and the short circuit state and the arc generation state are alternately
`generated by changing the wire feeding periodically and repeatedly between the
`fonNard feeding and the reverse feeding. The method offers arc welding with the
`average feeding rate according to a welding current, a predetermined frequency, and a
`predetermined velocity amplitude. In the method, at least any one of the frequency and
`the velocity amplitude is set to a value suitable for the welding current.
`
`Thus the determining feature for an average feed speed is taught for a suitable
`
`welding current at a predetermined frequency and velocity amplitude para 14, 40.
`
`19.
`
`Huismann teaches different speeds in col 8-10. A difference in speeds is
`
`considered optimization as noted in para 12 in Fujiwara.
`
`The Fujiwara reference is applicants' patent.
`
`Claims 1, 14 are argued. Fig 5 of Fujiwara teaches different waveforms above
`
`and below the AV. See para 11,39-at least one of,46. Para 60,61 ,62 are one
`
`embodiment showing a trapezoid. See (para 63) (fig 1,5,para 60-64) for different
`
`amplitudes. See col 3 lines 50-60 of Huismann and para 2,71 of Narayanan for
`
`improvements similar to Fujiwara and applicants.

`
`The prior art made of record and not relied upon is considered pertinent to
`
`applicant's disclosure. See WO 2007/094090 (US 2008/0314884) supplied by
`
`applicants.
`
`THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time
`
`policy as set forth in 37 CFR 1.136(a).
`
`A shortened statutory period for reply to this final action is set to expire THREE

`
`mailed until after the end of the THREE-MONTH shortened statutory period, then the
`
`shortened statutory period will expire on the date the advisory action is mailed, and any
`
`extension fee pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of
`
`the advisory action.
`
