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 . 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 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)(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. Claim(s) 1-5, 7, 8 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Campbell et al. (US 5613505). Campbell discloses in reference to claim: An article (fig. 12B) for use with apparatus 500 for heating smokable material to volatilize at least one component of the smokable material, wherein the article comprises: a mass of smokable material TM, and at least one heating substrate 400 (including individual wires 400 shown in fig. 10b) that consists entirely of heating material, wherein the heating material (SM) is a magnetic material heatable by penetration with a varying magnetic field to heat the smokable material – [NOTE: Applicant discloses the broadest interpretation of a magnetic material at as follows: [0059] Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by penetrating the object with a varying magnetic field. A magnetic material can be considered to comprise many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such material, the magnetic dipoles align with the magnetic field. Therefore, when a varying magnetic field, such as an alternating magnetic field, for example as produced by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes with the varying applied magnetic field. Such magnetic dipole reorientation causes heat to be generated in the magnetic material. Magnetic material is therefore interpreted to be any material that capable of Magnetic hysteresis heating. An induction source produces an alternating electromagnetic (EM) field which induces a heat generating eddy current in the susceptor. The discrete element of any suitable susceptor material SM heats the web W which is in intimate thermal contact therewith.] wherein the mass of smokable material TM is on the substrate 400 (on both top and bottom surfaces), and wherein an exterior of the article has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and the width, wherein the length is greater than or equal to the width, and wherein the width is greater than the depth. See Figure 10A Regarding the limitation that the substrate consist entirely of heating material, it is noted that the substrate 400 is disclosed as functional as a susceptor as described in reference to FIG. 10A. Further Campbell discloses integral layer 400 can be a screen, mesh or perforated foil of a suitable susceptor material and is intermeshed with, and preferably encapsulated or completely surrounded by, the tobacco flavor medium TM, as shown in FIGS. 10A and 10B and further discloses “possibly suitable susceptor materials may include conductive carbon such as graphite, aluminum, stainless steel, copper, bronze, or any combination thereof with aluminum alone or in combination being preferred.” [col. 9, line 65 to col. 10,line1) One of skill would interpret the scope of the teachings of Campbell to include a susceptor 400 made entirely of a heating material. Regarding the limitation that the substrate is within the mass of smokable material. Note Figure 10A shows the susceptor material 400 being located entirely within the smokable material TM. PNG media_image1.png 817 845 media_image1.png Greyscale PNG media_image2.png 522 899 media_image2.png Greyscale Regarding the new limitations wherein the substrate is a flat strip, and wherein the cross section of the substrate is constant along the length of the substrate, Applicant discloses: [0085] In each of the articles 1, 2, 3 shown in FIGS. 1 to 5, the cross section of the substrate 20 is constant along the length of the substrate 20. Moreover, in these embodiments, the substrate 20 is planar, or substantially planar. The substrate 20 of each of these embodiments could be considered a flat strip. However, in other embodiments, this may not be the case. It is noted that the disclosure does not provide any definition of “flat strip” aside from linking it to having a constant cross-section along the length of the substrate. As such the term “flat strip” does not serve to add definition the claim in any disclosed way. As such, for the purpose of examination, the term “flat strip” is considered to be met by any substrate structure that has a cross section that is constant along the length of the substrate. Campbell discloses in figure 10b individual lengthwise “wires” of the at least one substrate having a cross section that is constant along the length of the substrate. 2. The article of claim 1, wherein the mass of smokable material TM is fixed relative to the exterior of the article. See Figure 12B, TM is fixed relative to the exterior of the article. 3. The article of claim 1, wherein the heating material comprises one or more materials selected from the group consisting of: aluminum, gold, iron, nickel, cobalt, conductive carbon, graphite, plain-carbon steel, stainless steel, ferritic stainless steel, copper, and bronze. Note that Campbell discloses Possibly suitable susceptor materials may include conductive carbon such as graphite, aluminum, stainless steel, copper, bronze, or any combination thereof with aluminum alone or in combination being preferred. Materials having similar ranges of electrical resistivity and magnetic permeability can be employed alone or in combination. A desired susceptor thickness is between approximately 0.25 and 0.5 mil. 4. The article of claim 1, wherein the heating material is in contact with the smokable material. Note Campbell teach an intimate configuration of the smokable material and the heating means. The discrete element of any suitable susceptor material SM heats the web W which is in intimate thermal contact therewith. 5. The article of claim 1, wherein the heating material extends to opposite longitudinal ends of the mass of smokable material. See Fig. 10A 7. The article of claim 1, wherein the mass of smokable material defines at least a portion of the exterior of the article. Note the article is shown in Figure 10A the TM is clearly a portion of the exterior. 8. The article of claim 1, wherein the smokable material comprises reconstituted smokable material or is in the form of one of a gel, agglomerates, compressed material, or bound material. Fig. 10A shows the use of TM as the smokable material. Campbell further discloses in reference to TM that the web W may be made of the tobacco flavor medium TM itself, formed into an elongated sheet form by methods that are well known in, e.g., the manufacture of reconstituted tobacco products, as shown is FIG. 12A. The tobacco flavor medium is mixed with susceptor material SM as discussed above in reference to FIG. 8 if the web is used in the embodiment of FIG. 11, and, if desired, with the embodiment of FIG. 13 employing a separate susceptor element. Campbell discloses the provision of magnetic field generators for generating a varying magnetic field to be used in heating the smokable material when the portion of the article is located in the heating zone. PNG media_image3.png 633 1002 media_image3.png Greyscale 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 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. Claim(s) 1-5, 7, 8 is/are rejected under 35 U.S.C. 103 as being unpatentable over Campbell et al. (US 5613505). Campbell discloses in reference to claim: An article (fig. 12B) for use with apparatus 500 for heating smokable material to volatilize at least one component of the smokable material, wherein the article comprises: a mass of smokable material TM, and a substrate 400 that consists entirely of heating material, wherein the heating material (SM) is a magnetic material heatable by penetration with a varying magnetic field to heat the smokable material – [NOTE: Applicant discloses the broadest interpretation of a magnetic material at as follows: [0059] Magnetic hysteresis heating is a process in which an object made of a magnetic material is heated by penetrating the object with a varying magnetic field.

Therefore, when a varying magnetic field, such as an alternating magnetic field, for example as produced by an electromagnet, penetrates the magnetic material, the orientation of the magnetic dipoles changes with the varying applied magnetic field. Such magnetic dipole reorientation causes heat to be generated in the magnetic material. Magnetic material is therefore interpreted to be any material that capable of Magnetic hysteresis heating. An induction source produces an alternating electromagnetic (EM) field which induces a heat generating eddy current in the susceptor. The discrete element of any suitable susceptor material SM heats the web W which is in intimate thermal contact therewith.] wherein the mass of smokable material TM is on the substrate 400 (on both top and bottom surfaces), and wherein an exterior of the article has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and the width, wherein the length is greater than or equal to the width, and wherein the width is greater than the depth. See Figure 10A Regarding the limitation that the substrate consist entirely of heating material, it is noted that the substrate 400 is disclosed as functional as a susceptor as described in reference to FIG. 10A. Further Campbell discloses integral layer 400 can be a screen, mesh or perforated foil of a suitable susceptor material and is intermeshed with, and preferably encapsulated or completely surrounded by, the tobacco flavor medium TM, as shown in FIGS. 10A and 10B and further discloses “possibly suitable susceptor materials may include conductive carbon such as graphite, aluminum, stainless steel, copper, bronze, or any combination thereof with aluminum alone or in combination being preferred.” [col. 9, line 65 to col. 10,line1) One of skill would interpret the scope of the teachings of Campbell to include a susceptor 400 made entirely of a heating material. Regarding the limitation that the substrate is within the mass of smokable material. Note Figure 10A shows the susceptor material 400 being located entirely within the smokable material TM. PNG media_image1.png 817 845 media_image1.png Greyscale Regarding the new limitations wherein the substrate is a flat strip, and wherein the cross section of the substrate is constant along the length of the substrate, Applicant discloses: [0085] In each of the articles 1, 2, 3 shown in FIGS. 1 to 5, the cross section of the substrate 20 is constant along the length of the substrate 20. Moreover, in these embodiments, the substrate 20 is planar, or substantially planar. The substrate 20 of each of these embodiments could be considered a flat strip. However, in other embodiments, this may not be the case. It is noted that the disclosure does not provide any definition of “flat strip” aside from linking it to having a constant cross-section along the length of the substrate. As such the term “flat strip” does not serve to add definition the claim in any disclosed way. As such, for the purpose of examination, the term “flat strip” is considered to be met by any substrate structure that has a cross section that is constant along the length of the substrate. Campbell discloses in figure 8 a discrete substrate 300 having a cross section that is constant along the length of the substrate. The web W comprises or bears tobacco flavor medium. The web can have the general configuration described above in reference to FIGS. 8-10C. From this one of skill would understand that the configuration shown in Fig. 8 can be readily used in a more planar (non-cylindrical) application. Further, one of skill would then find it obvious that the embodiments shown in fig. 8 and fig. 10a, both being disclosed as useable in reference to fig. 12*, could be combined so as to yield a discrete substrate 300 (taught by fig. 8) being encapsulated by the TM (as taught by fig. 10a). It would have been obvious to one of skill in the art having the knowledge, creativity and common sense typically brought to bear when considering combinations or modifications to the state of the art to provide an embodiment of inductively heated tobacco medium having the combined structures shown in fig. 8 and 10a such as to arrive at the claimed invention combining the benefits of each of the configurations. 2. The article of claim 1, wherein the mass of smokable material TM is fixed relative to the exterior of the article. See Figure 12B, TM is fixed relative to the exterior of the article. 3. The article of claim 1, wherein the heating material comprises one or more materials selected from the group consisting of: aluminum, gold, iron, nickel, cobalt, conductive carbon, graphite, plain-carbon steel, stainless steel, ferritic stainless steel, copper, and bronze. Note that Campbell discloses Possibly suitable susceptor materials may include conductive carbon such as graphite, aluminum, stainless steel, copper, bronze, or any combination thereof with aluminum alone or in combination being preferred. Materials having similar ranges of electrical resistivity and magnetic permeability can be employed alone or in combination. A desired susceptor thickness is between approximately 0.25 and 0.5 mil. 4. The article of claim 1, wherein the heating material is in contact with the smokable material. Note Campbell teach an intimate configuration of the smokable material and the heating means. The discrete element of any suitable susceptor material SM heats the web W which is in intimate thermal contact therewith. 5. The article of claim 1, wherein the heating material extends to opposite longitudinal ends of the mass of smokable material. See Fig. 10A 7. The article of claim 1, wherein the mass of smokable material defines at least a portion of the exterior of the article. Note the article is shown in Figure 10A the TM is clearly a portion of the exterior. 8. The article of claim 1, wherein the smokable material comprises reconstituted smokable material or is in the form of one of a gel, agglomerates, compressed material, or bound material. Fig. 10A shows the use of TM as the smokable material. Campbell further discloses in reference to TM that the web W may be made of the tobacco flavor medium TM itself, formed into an elongated sheet form by methods that are well known in, e.g., the manufacture of reconstituted tobacco products, as shown is FIG. 12A. The tobacco flavor medium is mixed with susceptor material SM as discussed above in reference to FIG. 8 if the web is used in the embodiment of FIG. 11, and, if desired, with the embodiment of FIG. 13 employing a separate susceptor element. Campbell discloses the provision of magnetic field generators for generating a varying magnetic field to be used in heating the smokable material when the portion of the article is located in the heating zone. PNG media_image3.png 633 1002 media_image3.png Greyscale Claim 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Campbell. Campbell discloses the claimed invention except specficially that a portion of the substrate protrudes beyond an end of the mass of smokable material. See Figure 12G where the ends of the TM (591) are separated by areas of substrate web 592. The web W comprises or bears tobacco flavor medium. The web can have the general configuration described above in reference to FIGS. 8-10C. Fig. 10a discloses a flexible susceptor layer (or substrate 400) This discontinuous susceptor can be employed to heat tobacco flavor medium in any desired geometrical shape for smoking. One of skill in the art would recognize from the disclosure of Campbell that the configuration of fig. 10A could be modified to fit the geometrical configuration as shown in fig. 12G wherein a portion of the substrate 400 protrudes beyond an end of the mass of smokable material TM since it is disclosed that the configuration of fig 10A is particularly useful as a flexible article. Response to Arguments Applicant's arguments filed 07/18/2025 have been fully considered but they are not persuasive. Applicant argues that Figure 12b fails to show a susceptor comprised entirely of heating material because it depicts SM mixed with TM. It is noted again that Campbell explicitly states that any of the embodiments shown in figures 8-10c can be used in figure 12* and therefore figure 12b is not narrowly limited to that taught by figure 9. Further Applicant argues figure 12b cannot teach a “flat strip” however no definition of “flat strip” is provided in the original disclosure that would preclude the embodiments of figure 12b from being considered a “flat strip” wherein the cross-section is constant along the length of the substrate. Applicant’s argument regarding the disclosed preferred discontinuities of the substrate teaching away from the use of a substrate having a constant cross-section along the length are not persuasive as figure 10c shows a substrate having a both a constant cross-section and discontinuities simultaneously.
