`
`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 of this title, 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 1-13 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.

`Art Unit: 3742
`
`2.
`
`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: alternatively generating a
`
`short-circuit state and an arc state by feeding the welding wire in periodically alternating
`
`forward and backward directions at a predetermined frequency and a predetermined
`
`velocity amplitude with reference to a basic wire feed speed based on a set
`
`current(abstract); and
`
`3.
`
`controlling a speed of periodic feeding of the welding wire in such a manner that
`
`a waveform (para 63) to feed the welding wire is different between portion of the feeding
`
`performed at a speed above the basic wire feed speed and a portion of the feeding
`
`performed at a speed below the basic wire feed speed (fig 1,5,para 60-64).
`
`4.
`
`The claims at best differ in that there is a difference between waveforms for a
`
`particular direction.
`
`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,
`
`wherein the welding operation includes an arc state and a short circuit state that is
`
`repeated or cycled. See also Narayanan para 2, 71, fig 14. The references show
`
`changing and different waveforms for different directions and effects therefor.
`
`

`

`Application/Control Number: 13/820,557
`
`Page 4
`
`Art Unit: 3742
`
`6.
`
`It would have been obvious 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 spatter,
`
`defective beads and penetration. 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. See Fujiwara para 12,62, Huismann column 4, lines 6-22, col 8 line 44-52,
`
`Narayanan para 2, 71, fig 14.
`
`7.
`
`For claim 2: wherein the speed of periodic feeding of the welding wire is
`
`controlled in such a manner that the predetermined velocity amplitude is different
`
`between the forward and backward directions(fig 1,5).
`
`8.
`
`For claim 3: wherein a velocity amplitude in the forward direction is smaller than
`
`a velocity amplitude in the backward direction(fig 1,5).
`
`9.
`
`For claim 4: wherein a ratio of a short circuit period to an arc period is adjusted
`
`by setting a velocity amplitude in the fonNard direction to a product of a velocity
`
`amplitude in the backward direction and a ratio smaller than 1, thereby making the
`
`velocity amplitude in the forward direction smaller than the velocity amplitude in the
`
`backward direction(fig 1,5).
`
`10.
`
`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.
`
`

`

`
`Page 5
`
`Art Unit: 3742
`
`11.
`
`For claims 6,10-13: wherein the welding wire is fed in such a manner that the
`
`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.
`
`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 Fujiwara); and
`
`feeding a welding wire in periodically alternating forward and backward directions at a
`
`predetermined frequency and a predetermined velocity amplitude with reference to a
`
`basic wire feed speed based on the set current(abstract); wherein a feed speed of the
`
`welding wire is controlled in such a manner that an upper waveform of the feed speed
`
`higher than the basic wire feed speed is different from a lower waveform of the feed
`
`speed slower than the basic wire feed speed(fig 5 Fujiwara). See rejection of claim 1.
`
`For claim 15: wherein an upper velocity amplitude of the upper waveform is
`
`different from a lower velocity amplitude of the lower waveform(para 40,46,56 Fujiwara,
`
`col 8-10 Huismann, para 70,71 Narayanan).
`
`For claim 16: wherein the upper velocity amplitude is smaller than the lower
`
`velocity amplitude(matter of design choice and optimization relative to suitable operating
`
`parameters, not critical or producing any new or unexpected results).
`
`For claim 17: 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(fig 14 Narayanan, see claim 16).
`
`

`

`Application/Control Number: 13/820,557
`
`Page 6
`
`Art Unit: 3742
`
`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 Fujiwara).
`
`For claim 20: 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 Huismann, fig 14 Narayanan) .
`
`For claim 21 : wherein each shape of the upper waveform and the lower
`
`waveform is a part of a sinusoidal wave or trapezoidal wave(see claim 20).
`
`For claim 22: wherein each shape of the upper waveform and the lower
`
`waveform is a part of a sinusoidal wave or trapezoidal wave(see claim 20).
`
`For claim 23: wherein each shape of the upper waveform and the lower
`
`waveform is a part of a sinusoidal wave or trapezoidal wave(see claim 20).
`
`Applicant's arguments filed 6/29/2015 have been fully considered but they are
`
`not persuasive. The term "predetermined" in Fujiwara is not interpreted to just mean
`
`equal. 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. Claim 1
`
`is argued. Fig 5 of Fujiwara teaches different waveforms
`
`above and below the AV. The teachings of Fujiwara are broader than applicants’
`
`interpretation. See para 11,39-at least one of,46. Para 60,61 ,62 are one embodiment
`
`showing a trapezoid. See col 3 lines 50-60 of Huismann and para 2,71 of Narayanan for
`

`
`improvements similar to Fujiwara and applicants. Thus the remarks on page 9 second
`
`full paragraph are not understood.
`
`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.
`
`Applicant's amendment necessitated the new ground(s) of rejection presented in
`
`this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP
`
`§ 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37
`
`CFR1.136(a).
`
`A shortened statutory period for reply to this final action is set to expire THREE
`
`MONTHS from the mailing date of this action.
`
`In the event a first reply is filed within
`
`TWO MONTHS of the mailing date of this final action and the advisory action is not
`
`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.
`
`In no event, however, will the statutory period for reply expire later
`
`than SIX MONTHS from the date of this final action.
