Office Action

§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 . DETAILED ACTION Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 4/11/2026 has been entered. Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot because the new ground of rejection does not rely on the combination of references applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. 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. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1-3, 5, and 7, are rejected under 35 U.S.C. 103 as being unpatentable over Takahashi (JP H09324193 A), hereinafter Takahashi, in view of O’Connor (US 2570841 A), hereinafter O’Connor, and further in view of Downing (US 20200239183 A1), hereinafter Downing. Regarding claim 1, Takahashi discloses a sparkler birthday candle apparatus, comprising: a candle body (Figure 6) with a candle wick (18), the candle body further having an insertion hole at an upper portion of the candle body, the insertion hole being close to the candle wick (15); and a sparkler piece, which at the lower end is provided with an insertion portion adapted to be assembled on site into the insertion hole (“The present invention relates to the production of candle services at weddings, the production of various event industries and home parties such as birthdays” and “a hole (15) different from the core is opened in a candle, and the solid fireworks are inserted into the candle” and “A safe and efficient explosive component in which a small amount of sparks rise vertically” all citations are provided from the machine translation appended to the foreign reference). PNG media_image1.png 374 450 media_image1.png Greyscale Takahashi does not disclose: a package; a lower portion of the candle body having a projection at a lower end of said lower portion, the projection being adapted to be inserted into a birthday cake; the candle body and the sparkler piece being separate in the package. However, O’Connor teaches wherein a lower portion of the candle body is provided with a projection at a lower end of said lower portion (“a reinforcing stick 11 which may be made either of metal or wood. The stick desirably projects by an end well beyond the bottom end” column 1, line 45) to be inserted into a birthday cake (“Especially when applied to a cake for a birthday party, the instant candles have a captivating attraction for children” column 4, line 7). PNG media_image2.png 458 302 media_image2.png Greyscale In view of the teachings of O’Connor, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to include wherein a lower portion of the candle body is provided with a projection at a lower end of said lower portion to be inserted into a birthday cake as is taught in O’Connor, in the sparkler birthday candle disclosed by Takahashi because O’Connor states “Especially when applied to a cake for a birthday party, the instant candles have a captivating attraction for children.” Therefore, providing means for inserting the candle into a cake will improve visual appeal. Takahashi, as modified by O’Connor, does not disclose: a package; the candle body and the sparkler piece being separate in the package. However, Downing teaches: a package (“kit 40 is contained within an outer package 100” paragraph [0029]); the candle body and the auxiliary piece being separate in the package (“Kit 40, FIG. 1, includes a box 10 of candles, a box 14 of blank slips of paper as storage media, and a bag 18 of tubes such as cylinders” paragraph [0029]). PNG media_image3.png 572 254 media_image3.png Greyscale PNG media_image4.png 478 762 media_image4.png Greyscale In view of Downing’s teachings, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to include: a package; the candle body and the auxiliary piece being separate in the package as is taught in Downing, in the apparatus disclosed by Takahashi because Downing states “Another object of the present invention is to provide such a kit and method which may accommodate multiple events and/or multiple users” (paragraph [0007]) and “When different types of candles are included in the kit, a user can select his or her candle to have at least one visually perceptible indicia such as a color or type of striping that is unique to the user” (paragraph [0034]). Therefore, including the candles and auxiliary pieces separately will accommodate multiple events and/or users and enable customization. Regarding claim 2, Takahashi, as modified by O’Connor and Downing, discloses the apparatus, according to claim 1, wherein the insertion hole is a tapered hole with a large upper portion and a smaller lower portion (Figure 6b). Regarding claims 3 and 5, Takahashi, as modified by O’Connor and Downing, discloses the apparatus according to claim 2, wherein the central axis of the insertion hole and the central axis of the candle wick are parallel (Figure 6b). Takahashi, as modified by O’Connor and Downing, does not explicitly disclose the distance between the two central axes is not greater than 2.5 mm. However, the court has held a prima facie case of obviousness exists where the claimed ranges or amounts do not overlap with the prior art but are merely close. Titanium Metals Corp. of America v. Banner, 778 F.2d 775, 783, 227 USPQ 773, 779 (Fed. Cir. 1985). In this case, the figures of Takahashi suggest that the central axes of the wick and insertion hole are in close proximity. Additionally, the wick and pyrotechnics are ostensibly intended to be ignited either simultaneously or else one ignited by the other. Therefore, the distance disclosed in Takahashi will be close to the claimed range. Regarding claim 7, Takahashi discloses a sparkler candle apparatus comprising: a candle body, and a sparkler piece (Figure 6); the candle body having a candle wick (18); an upper portion of the candle body is provided with an insertion hole close to the candle wick (15); and the sparkler piece being adapted to be assembled on site into the insertion hole (“The present invention relates to the production of candle services at weddings, the production of various event industries and home parties such as birthdays” and “a hole (15) different from the core is opened in a candle, and the solid fireworks are inserted into the candle” and “A safe and efficient explosive component in which a small amount of sparks rise vertically” all citations are provided from the machine translation appended to the foreign reference). Takahashi does not disclose: a package; wherein a lower portion of the candle body is provided with a projection at a lower end of said lower portion to be inserted into an object; the candle body and the sparkler piece being separate in the package. However, O’Connor teaches wherein a lower portion of the candle body is provided with a projection at a lower end of said lower portion to be inserted into an object (“a reinforcing stick 11 which may be made either of metal or wood. The stick desirably projects by an end well beyond the bottom end” column 1, line 45) to be inserted into a birthday cake (“Especially when applied to a cake for a birthday party, the instant candles have a captivating attraction for children” column 4, line 7). In view of the teachings of O’Connor, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to include wherein a lower portion of the candle body is provided with a projection at a lower end of said lower portion to be inserted into an object as is taught in O’Connor, in the sparkler birthday candle disclosed by Takahashi because O’Connor states “Especially when applied to a cake for a birthday party, the instant candles have a captivating attraction for children.” Therefore, providing means for inserting the candle into a cake will improve visual appeal. Takahashi, as modified by O’Connor, does not disclose: a package; the candle body and the sparkler piece being separate in the package. However, Downing teaches: a package (“kit 40 is contained within an outer package 100” paragraph [0029]); the candle body and the auxiliary piece being separate in the package (“Kit 40, FIG. 1, includes a box 10 of candles, a box 14 of blank slips of paper as storage media, and a bag 18 of tubes such as cylinders” paragraph [0029]). In view of Downing’s teachings, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to include: a package; the candle body and the auxiliary piece being separate in the package as is taught in Downing, in the apparatus disclosed by Takahashi because Downing states “Another object of the present invention is to provide such a kit and method which may accommodate multiple events and/or multiple users” (paragraph [0007]) and “When different types of candles are included in the kit, a user can select his or her candle to have at least one visually perceptible indicia such as a color or type of striping that is unique to the user” (paragraph [0034]). Therefore, including the candles and auxiliary pieces separately will accommodate multiple events and/or users and enable customization. Claims 4 and 6 are rejected under 35 U.S.C. 103 as being unpatentable over Takahashi, in view of O’Connor, in view of Downing, and further in view of Namiki (JP H1055709 A), hereinafter Namiki. Regarding claims 4 and 6, Takahashi, as modified by O’Connor and Downing, discloses the apparatus according to claim 2. Takahashi, as modified by O’Connor and Downing, does not explicitly disclose wherein the angle of intersection between the central axis of the insertion hole and the central axis of the candle wick is 0.5 to 5 degrees (The examiner initially notes that an angle of 0.5° would potentially be within manufacturing tolerances of the device shown by Takahashi). However, Namiki teaches an angle of intersection between the central axis of the sparkler piece and the central axis of the candle wick (Figure 4). PNG media_image5.png 448 320 media_image5.png Greyscale In view of Namiki’s teachings, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the invention to include an angle of intersection between the central axis of the sparkler piece and the central axis of the candle wick as is taught in Namiki, in the sparkler birthday candle disclosed by Takahashi because angling the sparkler piece toward the wick will bring the wick and sparkler piece closer further enabling co-ignition of the wick and sparkler piece. Takahashi, as modified by O’Connor, Downing, and Namiki, does not disclose an angle of 0.5 to 5 degrees. However, there is a trigonometric relationship between the ignition point, the distance between the wick and insertion hole, and the angle between the wick axis and sparkler piece. For instance, a greater distance will require a greater angle to achieve the same proximity of wick and sparkler piece as compared to a smaller distance. Since the distance between the wick and insertion hole of Takahashi is small, only a small angle will be required. The court has held a prima facie case of obviousness exists where the claimed ranges or amounts do not overlap with the prior art but are merely close. Titanium Metals Corp. of America v. Banner, 778 F.2d 775, 783, 227 USPQ 773, 779 (Fed. Cir. 1985). In this case, the combined teachings of Takahashi as modified suggest a small angle. Therefore, the angle taught by the combination will be close to the claimed range. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Crasper (US 20120082947 A1) “The various components of the various candle assemblies described herein may be packaged as an assembled unit, as an unassembled kit including all or a portion of the components, as individual components, and in any combination thereof” paragraph [0040] Min (US 20180201874 A1) “The candle of the inventive concept may also be packaged and marketed as a kit.
