Office Action

§102 §103
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 Objections Claim 28 is objected to because of the following informalities: Claim 28 repeats "organism specific monoclonal antibody". Appropriate correction is required. 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) 21, 23-26, 28, 30 is/are rejected under 35 U.S.C. 102(1) as being anticipated by Chen et al. (US Pub No. 2018/0289616 A1, herein Chen). Regarding claim 1, Chen discloses a therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) comprising: a bandage matrix (substrate 31, Fig. 4); and an array of microneedles (dissolvable supporting structures 32 and carriers 33, Fig. 4) extending from the bandage matrix (“The dissolvable supporting structures are disposed on the substrate.” – Abstract, Fig. 4), each of the microneedles including a first layer (dissolvable supporting structures 32, Fig. 4) that encapsulates a first therapeutic agent (substances S2, Fig. 4) (“The substances S2 encapsulated in the dissolvable supporting structures 32…" - Para [0071]) and a second layer (carriers 33, Fig. 4) that encapsulates a second therapeutic agent (substances S1, Fig. 4) ("… the substance S1 encapsulated in the carriers…" - Para [0071]), wherein the array of microneedles is configured to deliver at least one of the first therapeutic agent or the second therapeutic agent from the bandage matrix (substrate 31, Fig. 4) into the skin of a patient (“…a delivery system capable of delivering substances through tissues, especially through skin…” – Para [0028]). Regarding claim 23, Chen discloses the therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) recited above, wherein the first layer (dissolvable supporting structures 32, Fig. 4) is configured to release the first therapeutic agent at a first rate ("… the dissolvable supporting structures 32 is able to release the substances S2 rapidly…" - Para [0072]), and the second layer (carriers 33, Fig. 4) is configured to release the second therapeutic agent at a second rate that is less than the first rate ("… the carriers 33 is able to provide the substances S1 in a sustained-release manner…" - Para [0072]). Examiner interprets S2 being released rapidly and S1 being released in a sustained-release manner as S1 being released at a different and slower rate than S2. Regarding claim 24, Chen discloses the therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) recited above, wherein the first layer (dissolvable supporting structures 32, Fig. 4) defines a first length ("…a height of the dissolving supporting structures ranges from 600 µm to 900 µm…" - Para [0026]) and the second layer (carriers 33, Fig. 4) defines a second length ("…a height of the dissolving supporting structures ranges from 600 µm to 900 µm…" - Para [0026]), the first layer being configured to release the first therapeutic agent at a first tissue depth (epidermis T1, Fig. 6A), the second layer being configured to release the second therapeutic agent at a second tissue depth (dermis T2, Fig. 6A) ("… the carriers 13 are able to penetrate the stratum corneum and reach the dermal layer of the skin…" - Para [0064]) that is different PNG media_image1.png 244 352 media_image1.png Greyscale than the first tissue depth (See Fig. 6A). Regarding claim 25, Chen discloses the therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) recited above, wherein the first layer is formed from a mixture of polyvinylpyrrolidone (PVP) and polyvinyl alcohol (PVA) ("… the supporting structures were made by different materials: PVP/PVA supporting structures…" - Para [0051]) and the second layer is formed from poly(lactic-co-glycolic acid) (PLGA) (“… the degradable carriers include… poly(lactic-co-glycolic acid)…" - Para [0015]) Regarding claim 26, Chen discloses the therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) recited above, wherein at least one of the first therapeutic agent and the second therapeutic agent comprise at least one of an immunomodulatory compound, a biological agent or an antimicrobial agent ("The substances delivered by the substance delivery device 1 of the present invention are not limited. Preferably, the substances may include a drug or biological active substances." - Para [0066]) Regarding claim 28, Chen discloses the therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) recited above, wherein the biological agent comprises at least one of an organism specific monoclonal antibody, anti-MecA anti-alpha toxin, or an organism-specific monoclonal antibody ("The biological active substances include but not limited to… antibody…" - Para [0066]) Examiner interprets antibody to include organism specific monoclonal antibody. Regarding claim 30, Chen discloses a method for fabricating a therapeutic bandage (“…the manufacturing method of the substance delivery device…” – Para [0078]), the method comprising forming a bandage matrix (substrate 31, Fig. 4) (“Manufacture of Dissolvable Supporting Structure… including the substrate of the present invention…” – Para [0083]-[0084]); and disposing an array of microneedles (dissolvable supporting structures 32 and carriers 33, Fig. 4) extending from the bandage matrix ("The dissolvable supporting structures are disposed on the substrate." - Abstract, Fig. 4), each of the microneedles including a first layer (dissolvable supporting structures 32, Fig. 4) that encapsulates a first therapeutic agent (substances S2, "The substances S2 encapsulated in the dissolvable supporting structures 32…" - Para [0071], Fig. 4) and a second layer (carriers 33, Fig. 4) that encapsulates a second therapeutic agent (substances S1, "… the substance S1 encapsulated in the carriers…" - Para [0071], Fig. 4), wherein the array of microneedles is configured to deliver at least one of the first agent or the second agent from the bandage matrix (substrate 31, Fig. 4) into the skin of a patient ("… a delivery system capable of delivering substances through tissues, especially through skin…" - Para [0028]). Regarding claim 32, Chen discloses the method for fabricating a therapeutic bandage (“…the manufacturing method of the substance delivery device…” – Para [0078]) as recited above, further comprising disposing within at least some of the microneedles at least one of an immunomodulatory compound, a biological agent, or an antimicrobial agent ("The substances delivered by the substance delivery device 1 of the present invention are not limited. Preferably, the substances may include a drug or biological active substances." - Para [0066]). 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. Claim(s) 22, 31, 33-34 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chen et al.

Regarding claim 22, Chen discloses the therapeutic bandage (substance delivery device 3, “The forms of TDD (transdermal drug delivery) include… patch… “ – Para [0005]) recited above, wherein Chen does not expressly disclose that the bandage matrix comprises a first bandage layer disposed on a film layer, a second bandage layer disposed on the first bandage layer, and a cellulose layer disposed on the second bandage layer, the array of microneedles protruding from the cellulose layer. PNG media_image2.png 196 472 media_image2.png Greyscale McAllister teaches that the bandage matrix (microneedle array 105, Fig. 2) comprises a first bandage layer (mechanical force indicator 155, Fig. 2) disposed on a film layer (handling layer 140, Fig. 2) ("…mechanical force indicator 155 is disposed between the adhesive layer 135 and the handling layer 140." - Para [0034]), a second bandage layer (adhesive layer 135, Fig. 2) disposed on the first bandage layer, and a cellulose layer (base substrate 110, Fig. 2) disposed on the second bandage layer, the array of microneedles protruding from the cellulose layer (“a base substrate 110 having a microneedle side 115” – Para [0033]). Therefore, it would have been obvious, before the effective filing date of the claimed invention, to modify the therapeutic bandage of Chen to include that the bandage matrix comprises a first bandage layer disposed on a film layer, a second bandage layer disposed on the first bandage layer, and a cellulose layer disposed on the second bandage layer, the array of microneedles protruding from the cellulose layer as taught by McAllister for application to a patient's skin (McAllister, Para [0019]). Regarding claim 31, Chen discloses the method for fabricating a therapeutic bandage (“…the manufacturing method of the substance delivery device…” – Para [0078]) as recited above, wherein the forming comprises: Chen does not expressly disclose disposing a first bandage layer on a film layer; disposing a second bandage layer on an opposing side of the first bandage layer; disposing a cellulose layer on an opposing side of the second bandage layer; and, configuring the microneedles to protrude from the cellulose layer. McAllister teaches disposing a first bandage layer (mechanical force indicator 155, Fig. 2) on a film layer (handling layer 140, Fig. 2) ("…mechanical force indicator 155 is disposed between the adhesive layer 135 and the handling layer 140." - Para [0034], Fig. 2); disposing a second bandage layer (adhesive layer 135, Fig. 2) on an opposing side of the first bandage layer ("…mechanical force indicator 155 is disposed between the adhesive layer 135 and the handling layer 140." - Para [0034], Fig. 2); disposing a cellulose layer (base substrate 110, Fig. 2) on an opposing side of the second bandage layer (Fig. 2); and, configuring the microneedles to protrude from the cellulose layer (“…step (e) may further form a base substrate connected to the primary funnel portion distal to the at least one microneedle.” – Para [0075]). Therefore, it would have been obvious, before the effective filing date of the claimed invention, to modify the method of Chen to include disposing a first bandage layer on a film layer; disposing a second bandage layer on an opposing side of the first bandage layer; disposing a cellulose layer on an opposing side of the second bandage layer; and, configuring the microneedles to protrude from the cellulose layer as taught by McAllister for application to a patient's skin (McAllister, Para [0019]). Regarding claim 33, Chen discloses a therapeutic bandage comprising: each of the microneedles (dissolvable supporting structures 32 and carriers 33, Fig. 4) including a first layer (dissolvable supporting structures 32, Fig. 4) that encapsulates a first therapeutic agent (substances S2, "The substances S2 encapsulated in the dissolvable supporting structures 32…" - Para [0071], Fig. 4) and a second layer (carriers 33, Fig. 4) that encapsulates a second therapeutic agent (substances S1, "… the substance S1 encapsulated in the carriers…" - Para [0071], Fig. 4), wherein the array of microneedles is configured to deliver at least one of the first therapeutic agent or the second therapeutic agent from the bandage matrix (substrate 31, Fig. 4) into the skin of a patient ("… a delivery system capable of delivering substances through tissues, especially through skin…" - Para [0028]).
