DETAILED ACTION
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.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 1-10, 20-26, and 34 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, 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.
Claim 1 recites the limitation:
but one independently controllable motor of the at least one independently controllable motor
it is unclear if the “but one independently controllable motor” is a single motor or any one motor, for the purpose of examination the examiner is interpreting the limitation to mean “a first motor”.
Claim 20 recites the limitation:
but one independently controllable motor of the at least one independently controllable motor
it is unclear if the “but one independently controllable motor” is a single motor or any one motor, for the purpose of examination the examiner is interpreting the limitation to mean “a first motor”.
Claim 20 recites the limitation:
a coupling that couples each arm in the first pair of SCARA arms simultaneously and substantially continuously to the at least one independently controllable motor by a coupling
it is unclear if the “a coupling that couples” and “motor by a coupling” refers to the same coupling or a different coupling, for the purpose of examination the examiner is interpreting the limitation as a typo with the correct form “a coupling that couples each arm in the first pair of SCARA arms simultaneously and substantially continuously to the at least one independently controllable motor by THE coupling”.
Claim 26 recites the term:
"substantially"
is a relative term which renders the claim indefinite. The term:
"substantially"
is not defined by the claim, the specification does not provide a standard for ascertaining the requisite degree, and one of ordinary skill in the art would not be reasonably apprised of the scope of the invention. It is unclear what stationary means in the context of “the other one of the crank links remains substantially stationary with respect to the support”. For the purpose of examination, the Examiner has interpreted the limitation “substantially stationary” to mean that the movement of the other one of the cranks links is substantially less than the movement of the one of the crank links driven to rotate the to cause movement of its respective transmission.
Regarding Claims 2-10, 21-25, and 34:
the claims are rejected for depending from a rejected claim
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of pre-AIA 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(e) the invention was described in (1) an application for patent, published under section 122(b), by another filed in the United States before the invention by the applicant for patent or (2) a patent granted on an application for patent by another filed in the United States before the invention by the applicant for patent, except that an international application filed under the treaty defined in section 351(a) shall have the effects for purposes of this subsection of an application filed in the United States only if the international application designated the United States and was published under Article 21(2) of such treaty in the English language.

pair of SCARA arms are spaced apart side by side (Fig. 16) and coupled to the but one independently controllable motor of the at least one independently controllable motor in order to effect a coordinated simultaneous extension and retraction of each of the first pair of arms [Column 23 Lines 54-63 & Column 26 Lines 11-64].
It would have been obvious to one of ordinary skill in the art at the time of invention to modify the transport apparatus having an articulated arm including a pair of SCARA arms extendable in a first direction which are independently actuatable relative to one another by a single drive motor taught by Saeki with the transport apparatus having an articulated arm including a pair of SCARA arms extendable in opposite directions with a coupling that couples the SCARA arms to a single drive motor in order to effect simultaneous extension and retraction of each of the first pair of arms taught by Okayama in order to provide a transfer apparatus with increased capacity and increased range for servicing multiple substrate processing chambers positioned both adjacent to and opposite to one another thereby increasing throughput in the system.
Regarding Claim 24, Saeki teaches:
the first and second SCARA arms are coupled together to independently extend and retract the first and second SCARA arms [0079 & 0080 & 0081 & 0082 & 0083].
Saeki does not teach:
the first and third SCARA arms are coupled together to simultaneously extend and retract and the second and fourth SCARA arms are coupled together to simultaneously extend and retract.
Okayama teaches:
the first pair of SCARA arms includes a first and third SCARA arms (101 & 104) or a second and fourth SCARA arms (101 & 104), coupled together and to the but one independently controllable motor of the at least one independently controllable motor in order to effect a coordinated simultaneous extension and retraction of each of the first and third SCARA arms or the second and fourth SCARA arms [Column 23 Lines 54-63 & Column 26 Lines 11-64].
It would have been obvious to one of ordinary skill in the art at the time of invention to modify the transport apparatus having an articulated arm including a pair of SCARA arms extendable in a first direction which are independently actuatable relative to one another by a single drive motor taught by Saeki with the transport apparatus having an articulated arm including a pair of SCARA arms extendable in opposite directions with a coupling that couples the SCARA arms to a single drive motor in order to effect simultaneous extension and retraction of each of the first and third SCARA arms or the second and fourth SCARA arms taught by Okayama in order to provide a transfer apparatus with increased capacity and increased range for servicing multiple substrate processing chambers positioned both adjacent to and opposite to one another thereby increasing throughput in the system.
Regarding Claim 25, Saeki teaches:
the coupling includes a first link (94A) coupled at one end to the but one independently controllable motor (Fig. 1 & Fig. 2 & Fig. 3 & Fig. 4) and at the other end to a first transmission coupling the first or third SCARA arm to the first link (Fig. 1 & Fig. 2) and a second link (94B) coupled at one end to the but one independently controllable motor (Fig. 1 & Fig. 2 & Fig. 3 & Fig. 4) and at the other end to a second transmission coupling the second or fourth SCARA arm to the second link (Fig. 1 & Fig. 2) [0079 & 0080 & 0081 & 0082 & 0083].
Saeki does not teach:
the first link coupled at the other end to a first transmission coupling the first and third SCARA arms to the first link and the second link coupled at the other end to a second transmission coupling the second and fourth SCARA arms to the second link
Okayama teaches:
the first pair of SCARA arms includes a first and third SCARA arms (101 & 104) or a second and fourth SCARA arms (101 & 104), coupled together and to the but one independently controllable motor of the at least one independently controllable motor in order to effect a coordinated simultaneous extension and retraction of each of the first and third SCARA arms or the second and fourth SCARA arms [Column 23 Lines 54-63 & Column 26 Lines 11-64].

Claim(s) 33 is/are rejected under 35 U.S.C. 103 as being unpatentable over Bacchi et al. (US 5741113 A) in view of Okayama et al. (US 6742977 B1).
Regarding Claim 33, Bacchi does not teach:
the connection between the first and second transmission members comprises a magnetic coupling.
Okayama teaches:
the connection between the first and second transmission members comprises a magnetic coupling [Column 26 Lines 18-37].
It would have been obvious to one of ordinary skill in the art at the time of invention to modify the transport apparatus having an articulated arm including an arm link and an end effector rotatably connected and longitudinally extendable in a first direction with a drive coupling utilizing transmission members to effect longitudinal motion in the system taught by Saeki with the articulated arm including an arm link and an end effector rotatably connected and longitudinally extendable in a first direction with a drive coupling utilizing transmission members to effect longitudinal motion in the system where the connection between the first and second transmission members comprises a magnetic coupling taught by Okayama in order to provide a transfer apparatus with a transmission assembly which has a motion transmission system which has an increased positive connection with less flaccidity in the connection in order to prevent misalignment due to stretching or slipping in the drive members.
