Office Action

§103 §112
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 . Status of the Claims This is a non-final rejection in response to the communication filed 12/29/2025. Claims 1-16 are currently pending. Claim Objections Claim 1 is objected to because of the following informalities: the claim recites the limitation “a plurality of motor top covers (11a) and motor base cover (11b) for encapsulating said motor (4)” in line 10-11. It appears the limitation of “the motor base cover (11b)” should read --motor base covers-- so as to be consistent in the use of claim terminology. Appropriate correction is required. Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention. Claims 1-16 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 1 recites the limitation "said blower" in line 10. It is unclear if reference is being made to the “plurality of blowers” earlier in the claim or if a new blower is being introduced. It appears the limitation should read --said plurality of blowers--. Claim 1 recites the limitation "said motor" in line 11. It is unclear if reference is being made to the “plurality of motors” earlier in the claim or if a new motor is being introduced. It appears the limitation should read --said plurality of motors--. Claim 1 recites the limitation "the bottom portion" in line 16. There is insufficient antecedent basis for this limitation in the claim. Regarding claim 2, the phrase "preferably" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 3, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 4, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 5, the phrase "preferably" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 6, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 8, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claim 9 recites the limitation “wherein said housing is made up of material including but not limited to sustainable materials such as bamboo or recycled plastic.” It is unclear if one or both materials are to be included. Regarding claim 9, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 9, the phrase "like" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 9, the phrase "such as" renders the claim indefinite because it is unclear whether the limitations following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 10, the phrase "not limited to any particular shape or size" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 12, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 14, the phrase "preferably" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 15, the phrase "preferably" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Regarding claim 16, the phrase "but not limited to" renders the claim indefinite because it is unclear whether the limitation(s) following the phrase are part of the claimed invention. See MPEP § 2173.05(d). Claims 2-16 are indefinite based on their dependency on claim 1. Claim Interpretation The following is a quotation of 35 U.S.C. 112(f): (f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The following is a quotation of pre-AIA 35 U.S.C. 112, sixth paragraph: An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof. The claims in this application are given their broadest reasonable interpretation using the plain meaning of the claim language in light of the specification as it would be understood by one of ordinary skill in the art. The broadest reasonable interpretation of a claim element (also commonly referred to as a claim limitation) is limited by the description in the specification when 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is invoked. As explained in MPEP § 2181, subsection I, claim limitations that meet the following three-prong test will be interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph: (A) the claim limitation uses the term “means” or “step” or a term used as a substitute for “means” that is a generic placeholder (also called a nonce term or a non-structural term having no specific structural meaning) for performing the claimed function; (B) the term “means” or “step” or the generic placeholder is modified by functional language, typically, but not always linked by the transition word “for” (e.g., “means for”) or another linking word or phrase, such as “configured to” or “so that”; and (C) the term “means” or “step” or the generic placeholder is not modified by sufficient structure, material, or acts for performing the claimed function. Use of the word “means” (or “step”) in a claim with functional language creates a rebuttable presumption that the claim limitation is to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites sufficient structure, material, or acts to entirely perform the recited function. Absence of the word “means” (or “step”) in a claim creates a rebuttable presumption that the claim limitation is not to be treated in accordance with 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. The presumption that the claim limitation is not interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, is rebutted when the claim limitation recites function without reciting sufficient structure, material or acts to entirely perform the recited function. Claim limitations in this application that use the word “means” (or “step”) are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. Conversely, claim limitations in this application that do not use the word “means” (or “step”) are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, except as otherwise indicated in an Office action. This application includes one or more claim limitations that use the word “means” or “step” but are nonetheless not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph because the claim limitation(s) recite(s) sufficient structure, materials, or acts to entirely perform the recited function. Such claim limitation(s) is/are: Bluetooth means in claim 14. Because this/these claim limitation(s) is/are not being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are not being interpreted to cover only the corresponding structure, material, or acts described in the specification as performing the claimed function, and equivalents thereof. If applicant intends to have this/these limitation(s) interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, applicant may: (1) amend the claim limitation(s) to remove the structure, materials, or acts that performs the claimed function; or (2) present a sufficient showing that the claim limitation(s) does/do not recite sufficient structure, materials, or acts to perform the claimed function. 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.

In Reference to Claim 9 Li, as modified by Ha, Kato, Zhang, Zeng and Liu, discloses the smart sustainable dual zone bladeless airflow device as claimed in claim 1, except, “... wherein said housing is made up of material including but not limited to sustainable materials such as bamboo or recycled plastic to reduce environmental impact ....” Shamshoian is also related to an integrated ceiling fixture (abstract), as the claimed invention, and teaches that integrated structures may be formed from sustainable material so ss to reduce environmental impact (¶ [0035]). Maletich is related to an airflow device (abstract), as the claimed invention, and teaches of housing of such structures may be formed from plastics (see ¶ [0033]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide in the system of Li wherein said housing (of Li) is made up of material including but not limited to sustainable materials such as bamboo or recycled plastic to reduce environmental impact (formed of sustainable materials including plastics as taught by Shamshoian and Maletich), so as to use an art known technique (of forming the housing of airflow devices of sustainable materials, including plastics as taught by Shamshoian and Maletich) into the system of Li and predictably form the housing. Claim(s) 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over CN 207393531 to Li (Li, and based on English Machine Translation) in view of US Patent Application Publication 2015/0132160 to Ha (Ha) in view of GB 2 327 817 to Kato et al.

(Liu, and based on English Machine Translation) as applied to claim 1 above, and further in view of US Patent Application Publication 2012/0326610 to Lawyer et al. (Lawyer). In Reference to Claim 11 Li, as modified by Ha, Kato, Zhang, Zeng and Liu, discloses the smart sustainable dual zone bladeless airflow device as claimed in claim 1, except, “... wherein said housing includes a display and a set of buttons to manually control for controlling said set of operations ....” Lawyer is related to a mounted integrated light housing (abstract), as the claimed invention, and teaches wherein said housing includes a display and a set of buttons to manually control for controlling said set of operations (¶ [0039]). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to provide in the system of Li wherein said housing (of Li) includes a display and a set of buttons to manually control for controlling said set of operations (as taught by Lawyer), so as to use an art known technique (of providing a control to a system on a housing of that system as taught by Lawyer) into the system of Li and predictably control the system.
