Office Action

§103
DETAILED ACTION 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 § 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. 2. Claims 1-5, 7-8 and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Penn (US 9,232,827). Penn discloses a baby helmet with a helmet body including a forehead protector (38,198) thereon that includes two pieces of closed cell foam/liner material (204,206) on left and right sides being connected by an adjustable elastic material/strap (218) that is an integrated structure, col. 10, lines 33- col. 11, line 11 and as shown in figures 5 and 34. Further, the baby helmet defines a plurality of air vents (196) therethrough fastened by an adjustable chin strap (190) as shown in figures 28 and 30. The baby helmet includes an adjustable connecting belt (190) that connects the left and right sides and about the chin as shown in figure 30. An interior of the helmet body is provided with a plurality of protruding parts (112, 114) as shown in figure 18. However, Penn does not show the closed foam material connecting the left and right sides. It would have been obvious to one skilled in the art before the effective date of the claimed invention that the closed cell foam material on the left and right sides of Penn are connected to each other by the elastic strap (218) as shown in figure 33 allowing the device to conform about different sized head. With regard to claim 3, it would have been obvious to one skilled in the art before the effective date of the claimed invention that the adjustable connecting chin belt of Penn can include but not limited to a chin rest, etc. providing proper support to the chin as known in the helmet art. Furthermore, with regard to claim 4, it would have been obvious to one skilled in the art before the effective date of the claimed invention that the adjustable connecting chin belt of Penn with a slide buckle substantially defining a Y shaped configuration as shown in figure 30 can include but not limited a Y-shaped connector, etc. as such fastening means is considered equivalent in the helmet making art. With regard to claim 5, col. 7, lines 1-32 of Penn discloses the forehead protector as shown in figure 5 with strap/belt having elastic ability. Therefore, it would have been obvious to one skilled in the art before the effective date of the claimed invention that the helmet body of Penn having the forehead protector held by the strap/belt with elastic ability will substantially allows a position of the forehead protector to be adjustable to fit different sized head. With regard to claim 7, it would have been obvious to one skilled in the art before the effective date of the claimed invention that the baby helmet of Penn can be provide but not limited to fabric layers on inner and outer sides, etc., in order to protect the helmet body from being damaged or depending on end use thereof 3. Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Penn as applied to claim 1 above, and further in view of Bell (EP 581460 A1). Penn discloses the invention as set forth above except for having the forehead protector with air vents. Bell discloses an infant helmet fastened by a chin strap (100) having a forehead protector with vents (12, 14) therethrough as shown in figure 5. It would have been obvious to one skilled in the art before the effective date of the claimed invention that the forehead protector of Penn can be provided with vents as taught by Bell in order to keep the wearer comfortable and cool when the device is donned. Response to Amendment The amendment and arguments filed on June 13, 2025 has been considered. In view of such this office action is made FINAL. Applicant argues that the prior art of Penn’827 and Bell ’460 does not disclose an elastic material being an integrated structure that connected two pieces of foam to easily adjust the head circumference of the helmet and having an interior of the helmet body with a plurality of protruding protective parts. The examiner respectfully disagrees since the prior art of Penn discloses a baby helmet having an elastic adjustable strap (218) that is integrally attached to the helmet as an integrated structure and has a plurality of protruding parts (112,114) attached to the interior of the helmet body as shown in figure 18. Further, it would have been obvious that the baby helmet of Penn can be provided with vents as disclosed by the prior art of Bell’460 for ventilation and keep the wearer cool. Conclusion 5. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The prior art references cited on PTO-892 each discloses an infant helmet made of impact absorbing material. THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
