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 .
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 (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 the appropriate paragraphs of 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 –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1-15, and 17, and 19 are rejected under 35 U.S.C. 102(a)(1) and 102(a)(2) as being anticipated by Busch et al (Patent Application Publication DE102020133405A1, hereinafter “Busch”). In regards to claim 1, Busch teaches an endoscope (figure 1 element 2) comprising:
a handle (figure 2 element 6) or interface
an insertion cord (Figure 1 element 12) extending from the endoscope handle or interface and configured to be inserted into a patient’s body cavity
the handle or interface comprising a Y-connector (figure 3 element 100) including: a first branch (figure 3 element 108 pointed two by the right arrow below) or socket having a first opening (figure 3 element 112) from which a first channel extends

In regards to claim 17, Busch teaches an endoscope wherein the first channel is formed to be configured to pre-bend an instrument inserted into the instrument insertion channel inside the first branch or socket through its curvature (channel is curved, and a straight, flexible instrument would be “pre-bent” by said curve as it enters the channel).
In regards to claim 19, Busch teaches a visualization system comprising: an endoscope and a monitor connectable to the endoscope (paragraph 2 “the present disclosure relates to… a system comprising the endoscope and a monitor” and paragraph 58 “such that the patient’s body cavity can be illuminated and inspected and can be viewed via the monitor M”).
Claim Rejections - 35 USC § 103
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.
Claim 16 is rejected 35 U.S.C. 103 as being unpatentable over Busch. In regards to claim 16, Busch teaches an endoscope wherein a diameter or circumference of the suction channel is smaller than a diameter or circumference of the instrument insertion channel. Busch fails to explicitly disclose wherein the diameter of the suction channel is smaller than that of the diameter of the instrument insertion channel.
However, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to make the diameter of the suction channel of Busch smaller than that of the instrument insertion channel since it has been held that “where the only difference between the prior art and the claims was a recitation of relative dimensions of the claimed device and a device having the claimed relative dimensions would not perform differently than the prior art device, the claimed device was not patentably distinct from the prior art device” Gardner v. TEC Syst., Inc., 725 F.2d 1338, 220 USPQ 777 (Fed. Cir. 1984), cert. denied, 469 U.S. 830, 225 SPQ 232 (1984). In the instant case, the suction channel would not operate differently with the claimed smaller diameter than that of the instrument insertion channel. Further, Applicant places no criticality on the range claimed, indicating that, in paragraph 38 of the specification, ”preferably, a cross-section, in particular a diameter or circumference, of the suction channel may be smaller than a cross-section, in particular a diameter or circumference, of the instrument insertion channel.” The specification does not impart criticality upon the relative dimensions of the suction and instrument insertion channels due to the limitation being something that “may” be included, meaning that a different relative relationship would also perform the intended function.
Claim 18 is rejected under 35 U.S.C. 103 as being unpatentable over Busch in view of Kunuki (U.S. Patent Application 2023/0320575). While Busch teaches the limitation of claims 1 and 12, it fails to teach an endoscope wherein the Y-connector is manufactured as an integral plastic piece. Kunuki teaches an endoscope wherein the Y-connector is manufactured as an integral plastic piece (paragraph 60 ”the branching member 50 is configured such that the body part 53 and the connecting member 60 are separate bodies, but these may be integrally molded”). It would have been obvious before the effective filing date of the claimed invention to one of ordinary skill in the art to modify the Y-connector of Busch to be manufactured as a single piece in order to save in manufacturing costs, as integral molding eliminates the need for assembly of multiple component pieces.
