Office Action

§102 §103
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 . Information Disclosure Statement The information disclosure statement (IDS) submitted is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. 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. Claim(s) 16-21, 28, 29, and 32-35 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Morimoto (JP 2578380). Regarding claim 16, Morimoto discloses an elongated housing component of an injection device (cylinder 3 in fig. 3), the elongated housing component comprising: a body (body of cylinder 3 in fig. 3) comprising a first longitudinal end (see below), an intermediate section (see below), and a second longitudinal end opposite to the first longitudinal end (see below), wherein the intermediate section is located longitudinally between the first longitudinal end and the second longitudinal end (see below), PNG media_image1.png 338 686 media_image1.png Greyscale wherein the body comprises a sidewall extending from the first longitudinal end to the second longitudinal end (see above), the sidewall confining a hollow interior space sized to accommodate a medicament container (the sidewall of cylinder 3 receives syringe 6 in fig. 3), and a magnifier extending through the sidewall or integrated into the sidewall to increase a visual appearance of at least a portion of the medicament container when the medicament container is inside the hollow interior space (cover 1 and lead glass 2 in fig. 3 form the “magnifier”; paragraph 5 of translation discloses that “a lens covers lead glass and has a transparent surface on which the inside of the radiation shielding device is magnified”). Regarding claim 17, Morimoto discloses the magnifier comprises a bulged section extending outwardly from the sidewall (fig. 2). Regarding claim 18, Morimoto discloses the magnifier is elongated and extends in a direction parallel to a longitudinal axis of the body (fig. 3). Regarding claim 19, Morimoto discloses the magnifier is located in the intermediate section of the body (see annotated figure above). Regarding claim 20, Morimoto discloses the magnifier extends along the intermediate section of the body (see annotated figure above). Regarding claim 21, Morimoto discloses the intermediate section comprises a first outer diameter (see below), the second longitudinal end comprises a second outer diameter (see below; the examiner notes that “diameter” is defined by Merriam-Webster as “the length of a straight line through the center of an object”; the diameter below is the length of the straight line extending through wing 4 which is part of the second longitudinal end), and the first outer diameter is smaller than the second outer diameter (see below). PNG media_image2.png 304 520 media_image2.png Greyscale Regarding claim 28, Morimoto discloses the second longitudinal end comprises a connector operable to mechanically connect to a corresponding connector of a further housing component of the injection device (wing 4 in fig. 6 is functionally capable of connecting to a further housing since the particulars of the housing are not further claimed). Regarding claim 29, Morimoto discloses the magnifier (i) comprises a bulged section extending outwardly from the sidewall (fig. 2), (ii) is elongated and extends in a direction parallel to a longitudinal axis of the body (fig. 3), (iii) is located in the intermediate section of the body (fig. 3 and see annotated figure above), and (iv) extends along the intermediate section of the body (fig. 3 and see annotated figure above). Regarding claim 32, Morimoto discloses an injection device for injecting of a dose of a liquid medicament (fig. 3), the injection device comprising: a first housing (cylinder 3 and wing 4 in fig. 6 are the “first housing”) comprising an elongated housing component (cylinder 3 in fig. 3), the elongated housing component being configured to accommodate a medicament container at least partially filled with the liquid medicament (fig. 3 shows cylinder receiving syringe 6); a magnifier extending through a sidewall of the elongated housing component or integrated into the sidewall to increase a visual appearance of at least a portion of the medicament container when the medicament container is arranged in the elongated housing component (cover 1 and glass 2 in fig. 2 and 3 form the “magnifier”; paragraph 5 of translation discloses that “a lens covers lead glass and has a transparent surface on which the inside of the radiation shielding device is magnified”); and a second housing component connectable or connected to the elongated housing component (cap 5 is connected to cylinder 3 in fig. 3), the second housing component being sized or configured to accommodate a drive mechanism configured to engage with the medicament container to expel or to withdraw the dose of the liquid medicament from the medicament container (fig. 3 shows that cap 5 comprises a hole 8 which accommodates plunger 9 therethrough which engages with the syringe 6 to expel the fluid within syringe 6). Regarding claim 33, Morimoto discloses the medicament container arranged inside the elongated housing component (syringe 6 in fig. 3), the medicament container at least partially filled with the liquid medicament (paragraph 5 of the provided translation discloses the syringe “is pre-filled with a radiopharmaceutical solution”). Regarding claim 34, Morimoto discloses the magnifier comprises a bulged section extending outwardly from the sidewall of the elongated housing component (fig. 2). Regarding claim 35, Morimoto discloses the magnifier is configured to magnify at least the portion of the medicament container (paragraph 5 of the provided translation discloses “a lens that covers the lead glass and has a transparent surface on which the inside of the radiation shielding device is magnified”). 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(s) 22-24 is/are rejected under 35 U.S.C. 103 as being unpatentable over Morimoto, as applied to claim 16 above, and further in view of Sexton (US 20200101232) and in view of Jensen (US 6312413). Regarding claim 22, Morimoto discloses all of the claimed limitations set forth in claim 16, as discussed above, but does not teach or disclose the intermediate section comprises a polygonal cross-section with at least a first sidewall section, a second sidewall section, and a third sidewall section, and the first sidewall section, the second sidewall section, and the third sidewall section are adjoined to each other along a first or second tangential direction. Sexton is drawn to an elongated housing component (syringe body 60 in fig. 2) which is adapted to receive a medicament container (cartridge 22 in fig. 2). Sexton teaches that the length of the elongated housing component comprises a circular cross-section (fig. 2) but can alternatively be triangular (paragraph 30). Jensen is directed towards an injection device comprising a triangular cross-section (fig. 1) and teaches that this type of cross-section comprises a first sidewall section, a second sidewall section, and a third sidewall section (see below), and the first sidewall section, the second sidewall section, and the third sidewall section are adjoined to each other along a first or second tangential direction (see below). PNG media_image3.png 388 464 media_image3.png Greyscale Therefore, it would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have modified the elongated housing component (cylindrical body 3 in fig. 3), including the intermediate section, and the medicament container (syringe 6 in fig. 3) of Morimoto to be triangular, as taught by Sexton, so that the intermediate section comprises a polygonal cross-section with at least a first sidewall section, a second sidewall section, and a third sidewall section, and the first sidewall section, the second sidewall section, and the third sidewall section are adjoined to each other along a first or second tangential direction, as taught by Jensen. Jenson teaches that modifying the shape of the components to be triangular with the claimed sidewall sections will not impact operation of a device, specifically by providing an injection device which is configured to deliver a fluid. Additionally, it has been held that a change in form or shape is generally recognized as being within the level of ordinary skill in the art. In re Dailey, 149 USPQ 47 (CCPA 1976). Regarding claim 23, in the modified device of Morimoto, Jensen discloses the first sidewall section adjoins in the first tangential direction to the second sidewall section along a first ridge portion, the second sidewall section adjoins in the first tangential direction to the third sidewall section along a second ridge portion, the first sidewall section adjoins in the second tangential direction to the third sidewall section along a third ridge portion, and the second tangential direction is opposite to the first tangential direction (see below). PNG media_image4.png 340 427 media_image4.png Greyscale Regarding claim 24, in the modified device of Morimoto, the magnifier of Morimoto (cover 1 and glass 2 in fig. 3) extend along a minor part of the circumference of the perimeter of the body (cylindrical body 3 in fig. 1). The examiner asserts that POSITA would recognize that modifying the body of Morimoto (i.e. cylindrical body 3 in fig. 1) to comprise a triangular shape taught by Sexton and Jenson above would encompass placing the magnifier on one of the sidewall sections between ridges with this sidewall being considered the “first sidewall section”. Claim(s) 25 and 31 is/are rejected under 35 U.S.C. 103 as being unpatentable over Morimoto in view of Sexton and in view of Jensen, as applied to claims 16, 22, and 29 above, and further in view of Oakley (US 20160166775). Regarding claim 25, modified Morimoto teaches all of the claimed limitations set forth in claims 16 and 22, as discussed above, but does not teach or disclose at least the first sidewall section has a convex shape along the first tangential direction. Oakley is directed towards a drug delivery device (fig. 1) comprising an elongated body (housing 10 in fig. 1) which comprises a triangular cross-section paragraph 128; fig. 9 and 10) having first, second, and third sidewall sections (figs. 9 and 10) which are each convex along a first tangential direction (figs. 9 and 10; paragraph 128 discloses a “rounded” triangular shape). Therefore, it would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have modified the sidewall sections of modified Morimoto to be convex along the first tangential direction, as taught by Oakley, since Oakley teaches that this shape is comfortable to hold and handle the device (paragraph 120). Regarding claim 31, Morimoto discloses all of the claimed limitations set forth in claims 16 and 29, as discussed above, but does not teach or disclose the intermediate section comprises a polygonal cross-section with at least a first sidewall section, a second sidewall section, and a third sidewall section, the first sidewall section adjoins in a first tangential direction to the second sidewall section along a first ridge portion, the second sidewall section adjoins in the first tangential direction to the third sidewall section along a second ridge portion, the first sidewall section adjoins in a second tangential direction to the third sidewall section along a third ridge portion, the second tangential direction is opposite to the first tangential direction, the magnifier is located on the first sidewall section between the first ridge portion and the third ridge portion, and at least the first sidewall section has a convex shape along the first tangential direction. As discussed previously, Sexton is drawn to an elongated housing component (syringe body 60 in fig. 2) which is adapted to receive a medicament container (cartridge 22 in fig. 2). Sexton teaches that the length of the elongated housing component comprises a circular cross-section (fig. 2) but can alternatively be triangular (paragraph 30). Jensen is directed towards an injection device comprising a triangular cross-section (fig. 1) and teaches that this type of cross-section comprises first sidewall section, a second sidewall section, and a third sidewall section (see below), and the first sidewall section adjoins in the first tangential direction to the second sidewall section along a first ridge portion, the second sidewall section adjoins in the first tangential direction to the third sidewall section along a second ridge portion, the first sidewall section adjoins in the second tangential direction to the third sidewall section along a third ridge portion, and the second tangential direction is opposite to the first tangential direction (see below). PNG media_image5.png 340 427 media_image5.png Greyscale Therefore, it would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have modified the elongated housing component (cylindrical body 3 in fig. 3), including the intermediate section, and the medicament container (syringe 6 in fig. 3) of Morimoto to be triangular, as taught by Sexton, so that the intermediate section comprises a polygonal cross-section with at least a first sidewall section, a second sidewall section, and a third sidewall section, and the first sidewall section adjoins in the first tangential direction to the second sidewall section along a first ridge portion, the second sidewall section adjoins in the first tangential direction to the third sidewall section along a second ridge portion, the first sidewall section adjoins in the second tangential direction to the third sidewall section along a third ridge portion, and the second tangential direction is opposite to the first tangential direction, as taught by Jensen. Jenson teaches that modifying the shape of the components to be triangular with the claimed sidewall sections will not impact operation of a device, specifically by providing an injection device which is configured to deliver a fluid. Additionally, it has been held that a change in form or shape is generally recognized as being within the level of ordinary skill in the art. In re Dailey, 149 USPQ 47 (CCPA 1976). The examiner notes that the magnifier of Morimoto (cover 1 and glass 2 in fig. 3) extend along a minor part of the circumference of the perimeter of the body (cylindrical body 3 in fig. 1). The examiner asserts that POSITA would recognize that modifying the body of Morimoto (i.e. cylindrical body 3 in fig. 1) to comprise a triangular shape taught by Sexton and Jenson above would encompass placing the magnifier on one of the sidewall sections between ridges with this sidewall being considered the “first sidewall section”. Oakley is directed towards a drug delivery device (fig. 1) comprising an elongated body (housing 10 in fig. 1) which comprises a triangular cross-section paragraph 128; fig. 9 and 10) having first, second, and third sidewall sections (figs. 9 and 10) which are each convex along a first tangential direction (figs. 9 and 10; paragraph 128 discloses a “rounded” triangular shape). Therefore, it would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have modified the sidewall sections of modified Morimoto to be convex along the first tangential direction, as taught by Oakley, since Oakley teaches that this shape is comfortable to hold and handle the device (paragraph 120). Claim(s) 26, 27, and 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Morimoto, as applied to claims 16 and 29 above, and further in view of Shonfeld (US 5891104). Regarding claim 26, Morimoto discloses all of the claimed limitations set forth in claim 16, as discussed above, but does not teach or disclose the body comprises at least one through opening extending through the sidewall to provide access to the medicament container when the medicament container is in the body. Shonfeld is directed towards an injection device (fig. 1A) comprising a body (barrel 10 in fig. 1B) which is adapted to receive a medicine container (ampoule 40 in fig. 1). Shonfeld further teaches that the body comprises at least one through opening extending through the sidewall to provide access to the medicament container when the medicament container is in the body (notches 17 in fig. 1B are shown to extend through the sidewall of barrel 10 and would allow for access to a portion of the ampoule 40). Shonfeld further teaches that these openings are part of a track (groove 16 in fig. 1B) which allows for needle retraction (fig. 4A/B). Therefore, it would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have modified the device of Morimoto to allow for needle retraction by modifying the body to comprise at least one through opening extending through the sidewall as well as a track which can engage a needle head of the device, as taught by Shonfeld, in order to prevent accidental needle sticks (2:1-3). Regarding claim 27, in the modified device of Morimoto, Shonfeld discloses the at least one through opening comprises a first through opening and a second through opening (see below), the first through opening and the second through opening extending through the sidewall (see below), and the first through opening is located diametrically opposite to the second through opening (see below). PNG media_image6.png 330 342 media_image6.png Greyscale Regarding claim 30, Morimoto discloses all of the claimed limitations set forth in claims 16 and 29, as discussed above, but does not teach or disclose the body comprises a first through opening and a second through opening, the first through opening and the second through opening extending through the sidewall to provide access to the medicament container when the medicament container is in the body, and the first through opening being located diametrically opposite to the second through opening. As discussed above, Shonfeld is directed towards an injection device (fig. 1A) comprising a body (barrel 10 in fig. 1B) which is adapted to receive a medicine container (ampoule 40 in fig. 1). Shonfeld further teaches that the body a first through opening and a second through opening, the first through opening and the second through opening extending through the sidewall to provide access to the medicament container when the medicament container is in the body, and the first through opening being located diametrically opposite to the second through opening (see annotated figure for claim 27 above; notches 17 in fig. 1A/B are shown to extend through the sidewall of barrel 10 and would allow for access to a portion of the ampoule 40). Shonfeld further teaches that these openings are part of a track (groove 16 in fig. 1B) which allows for needle retraction (fig. 4A/B). Therefore, it would have been obvious to one of ordinary skill before the effective filing date of the claimed invention to have modified the device of Morimoto to allow for needle retraction by modifying the body to comprise the claimed first and second through openings extending through the sidewall as well as a track which can engage a needle head of the device, as taught by Shonfeld, in order to prevent accidental needle sticks (2:1-3).
