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 .
Specification
Applicant is reminded of the proper language and format for an abstract of the disclosure.
The abstract should be in narrative form and generally limited to a single paragraph on a separate sheet within the range of 50 to 150 words in length. The abstract should describe the disclosure sufficiently to assist readers in deciding whether there is a need for consulting the full patent text for details.
The language should be clear and concise and should not repeat information given in the title. It should avoid using phrases which can be implied, such as, “The disclosure concerns,” “The disclosure defined by this invention,” “The disclosure describes,” etc. In addition, the form and legal phraseology often used in patent claims, such as “means” and “said,” should be avoided.
The abstract of the disclosure is objected to because: a plurality of lines state the phrase "said", which is considered to be implied language. Correction is required. See MPEP 608.01(b). A corrected abstract of the disclosure is required and must be presented on a separate sheet, apart from any other text. See MPEP § 608.01(b).
Claim Rejections - 35 USC § 103
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 (i.e., changing from AIA to pre-AIA ) 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 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- 20 are rejected under 35 U.S.C. 103 as being unpatentable over MacLachlan (United States Patent US 7,070,043 B1) in view of Andersen (United States Patent Application US 2011/0017576A1).
Regarding Claim 1, MacLachlan discloses A modular conveyor belt link configured to be assembled in interfitting relationship with a plurality of like modular conveyor belt links, which may be connected together with connection pins to form an endless conveyor belt with a load carrying surface and an underside opposite the load carrying surface, the endless conveyor belt defining a forward direction and a rearward direction extending in opposing directions along a conveying path, and a belt thickness between the load carrying surface and the underside of the belt, (Figure 2: Conveyor belt 10)the modular conveyor belt link comprising: a main body having a first thickness configured to define the belt thickness when the link is assembled with other links; (Figure 23: Module 24 with a thickness defining the belt thickness)a plurality of central eye parts extending perpendicularly from said main body in forward and rearward directions, each said central eye part also being of said first thickness;(Figure 3: Hinge eyes 42, 43).
However, MacLachlan does not disclose an outermost end structure on a first end of said modular conveyor belt link, said outermost end structure comprising: a first end eye part being of said first thickness, extending from said main body in a first direction along the conveying path, providing an engagement surface for engaging a driving rib of a drive element, and defining an outer side surface of the link, and a second end eye part extending from said main body in a second direction opposite the first direction along the conveying path and including a rib blocking structure having a second thickness that is less than said first thickness, said rib blocking structure being configured to prevent lateral engagement of the driving rib inward between the link and an adjacent link beyond said rib blocking structure.
Andersen discloses a similar modular conveyor belt link comprising an outermost end structure on a first end of said modular conveyor belt link, said outermost end structure comprising: a first end eye part being of said first thickness, extending from said main body in a first direction along the conveying path, providing an engagement surface for engaging a driving rib of a drive element, and defining an outer side surface of the link,(Paragraph 0027: "The edge element 20 together form an outwardly predominantly closed guide surface 34 as the edge elements 20 at the front, i.e. in the direction of movement, has a lower forward projecting part 36 and at the rear a upper rearward projecting part 38 such that, as seen from above, a predominantly closed guide surface 34 is formed, which e.g. will prevent the sharp edges of the vertical curve guides 8 from interfering with the lateral apertures 18 which are now well out of the way behind the edge elements 20.", wherein Figure shows inner side part 24 of edge element 20, which forms a first end eye part on the right side of the link) and a second end eye part extending from said main body in a second direction opposite the first direction along the conveying path and including a rib blocking structure having a second thickness that is less than said first thickness, (Figure54: Lower forward projecting part 36)said rib blocking structure being configured to prevent lateral engagement of the driving rib inward between the link and an adjacent link beyond said rib blocking structure.(Paragraph 0027: "The edge element 20 together form an outwardly predominantly closed guide surface 34 as the edge elements 20 at the front, i.e. in the direction of movement, has a lower forward projecting part 36 and at the rear a upper rearward projecting part 38 such that, as seen from above, a predominantly closed guide surface 34 is formed, which e.g. will prevent the sharp edges of the vertical curve guides 8 from interfering with the lateral apertures 18 which are now well out of the way behind the edge elements 20.").
It would have been obvious to one skilled in the art before the effective filing date of the claimed invention to have modified MacLachlan to include the engagement surface for a rib, as well as a rib blocking structure as taught by Andersen. The motivation for the modification would have been to allow for a substantially closed guide surface to counteract issues of lateral incisions or apertures at the belt edges (Paragraph 0005).
Regarding Claim 2, MacLachlan in view of Andersen discloses the modular conveyor belt link of claim 1, as seen above.
