Office Action

§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 . 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 June 22, 2026 has been entered. 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 do not use the word “means,” but are nonetheless being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because the claim limitation(s) uses a generic placeholder that is coupled with functional language without reciting sufficient structure to perform the recited function and the generic placeholder is not preceded by a structural modifier. Such claim limitation(s) is/are: “at least one heating device” in claim 1. Because this/these claim limitation(s) is/are being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, it/they is/are being interpreted to cover the corresponding structure described in the specification as performing the claimed function, and equivalents thereof. If applicant does not intend 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 avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph (e.g., by reciting sufficient structure to perform the claimed function); or (2) present a sufficient showing that the claim limitation(s) recite(s) sufficient structure to perform the claimed function so as to avoid it/them being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. Claim Rejections - 35 USC § 112 The following is a quotation of the first paragraph of 35 U.S.C. 112(a): (a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention. The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112: The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention. Claims 1-2 and 17 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention. Amended independent claim 1 recites the limitation "determine whether the temperatures of the first chamber and the second chamber are the predetermined temperature; and in response to a determination that the temperatures of the first chamber and the second chamber are the predetermined temperature, control the driver to move the cells cultured in the first closed container to the second closed container," however, said limitation constitutes new matter. The instant specification, as originally filed, discloses in paragraph [0044] that the cell suspension containing cells in the closed container (50) is recovered (step S8). The cell suspension inside the closed container moves to the stirring part through tube 71. Next, as discussed in paragraph [0045], the controller check whether both the temperatures and carbon dioxide concentrations inside the first chamber and second chamber are predetermined values (step S10). If the temperatures and carbon dioxide concentrations inside the first chamber and second chamber are at the predetermined values, the cell suspension inside the stirring part 32 is moved to the closed container 60 (step S12; paragraph [0046]). The claims as currently presented require that the controller to control the driver to move the cells cultured in the first closed container to the second closed container in response to a determination that the temperatures of the first chamber and the second chamber are the predetermined temperature. However, as discussed above, the cell suspension inside the closed container (50) moves to the stirring part through tube 71 prior to the determination of the temperature in the first and second chambers. In that, prior to determining whether the temperature in the first and second container is at predetermined temperature, the cell suspension has already been moved to the stirring part. After determining whether the temperature inside the first chamber and second chamber are predetermined value, the cell suspension moves from the stirring part to the second closed container. As such, said limitation constitutes new matter. Claims 2 and 17 are rejected by virtue of their dependency upon a rejected base claim. Independent claim 1 recites the limitation "at least one heating device," however, said limitation fails to comply with written description requirement. 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. Claim limitation “at least one heating device” has been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses a generic placeholder “device” coupled with functional language “heating” without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is not preceded by a structural modifier. The term "device" is not limited to a specific structure for performing the recited function(s). The term "device" is considered to be non-structure modifier that fails to recite sufficiently definite structure, material or acts to perform the claimed function. The instant specification, as originally filed, discloses an environment adjustment part having a built-in heating device (see paragraph [0025] of the application publication). However, Applicant’s disclosure is silent as to the structure that comprise the claimed heating device (i.e., what structure does the heating device comprise?). As such, said limitation fails to comply with the written description requirement. 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 1-2 and 17 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 limitations "a connection path configured to connect the first closed container and the second closed container" in lines 9-10, “remove the first closed container as a cell movement source from the connection path while maintaining an aseptic state inside the second closed container, to which the cells are moved, and inside the connection path” in lines 18-20, “after the first closed container is removed from the connection path, connect a third closed container, which is configured to culture the cells and is loaded into the first chamber via the first opener/closer to the connection path while maintaining an aseptic state inside the third closed container and inside the connection path” in lines 21-24, and “a driver configured to move the cells between the first closed container and the second closed container via the connection path and move the cells between the second closed container and the third closed container via the connection path” in lines 25-27, and “in response to a determination that the temperatures of the first chamber and the second chamber are the predetermined temperature, control the driver to move the cells cultured in the first closed container to the second closed container” in lines 37-39. However, the first, second and third closed containers are not positively recited as a structural elements of the claimed cell culture device. As currently presented, the claim requires the first, second and third closed containers to be in a structural relationship with the components of the claimed cell culture device. While the closed containers are recited in a specific configurations with the components of the claimed cell culture device, the closed containers themselves are never affirmatively claimed. It is therefore remains unclear whether the prior art must teach the closed containers having this structural relationship in order to meet the claimed invention. Further clarification is requested and appropriate correction is required. Claim 1 recites the limitation " after the cells are moved from the first closed container to the second closed container and while the moved cells are cultured in the second closed container" in lines 15-17. However, cell movement between the first and second closed containers was not previously recited in the claim. Thus, it is unclear as to the cell movement the limitation is referring to. Claim 1 recites the limitation "at least one temperature sensor configured to detect temperatures inside the first chamber and the second chamber" in lines 28-29. It is unclear if one temperature sensor is coupled to each of the first and second chambers, or one temperature sensor is coupled to both the first and second chambers. Claim limitation “at least one heating device” invokes 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph. However, the written description fails to disclose the corresponding structure, material, or acts for performing the entire claimed function and to clearly link the structure, material, or acts to the function. Independent claim 1 further recites the limitation "at least one heating device," however, said limitation fails to comply with written description requirement. 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. Claim limitation “at least one heating device” has been interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph, because it uses a generic placeholder “device” coupled with functional language “heating” without reciting sufficient structure to achieve the function. Furthermore, the generic placeholder is not preceded by a structural modifier. The term "device" is not limited to a specific structure for performing the recited function(s). The term "device" is considered to be non-structure modifier that fails to recite sufficiently definite structure, material or acts to perform the claimed function. The instant specification, as originally filed, discloses an environment adjustment part having a built-in heating device (see paragraph [0025] of the application publication). However, Applicant’s disclosure is silent as to the structure that comprise the claimed heating device (i.e., what structure does the heating device comprise?). Therefore, the claim is indefinite and is rejected under 35 U.S.C. 112(b) or pre-AIA 35 U.S.C. 112, second paragraph. Applicant may: (a) Amend the claim so that the claim limitation will no longer be interpreted as a limitation under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph; (b) Amend the written description of the specification such that it expressly recites what structure, material, or acts perform the entire claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (c) Amend the written description of the specification such that it clearly links the structure, material, or acts disclosed therein to the function recited in the claim, without introducing any new matter (35 U.S.C. 132(a)). If applicant is of the opinion that the written description of the specification already implicitly or inherently discloses the corresponding structure, material, or acts and clearly links them to the function so that one of ordinary skill in the art would recognize what structure, material, or acts perform the claimed function, applicant should clarify the record by either: (a) Amending the written description of the specification such that it expressly recites the corresponding structure, material, or acts for performing the claimed function and clearly links or associates the structure, material, or acts to the claimed function, without introducing any new matter (35 U.S.C. 132(a)); or (b) Stating on the record what the corresponding structure, material, or acts, which are implicitly or inherently set forth in the written description of the specification, perform the claimed function. For more information, see 37 CFR 1.75(d) and MPEP §§ 608.01(o) and 2181. Appropriate correction is required. Response to Arguments Applicant’s arguments with respect to claim(s) 1-3 and 17 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
