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 is: power component in claim 11.
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.
The following claim limitations : “power component” in claim 11; “first coating member” and “second coating member” in claim 11; and “transfer unit” in claims 11 and 17 are no longer being interpreted under 35 U.S.C. 112(f) or pre-AIA 35 U.S.C. 112, sixth paragraph based on the amendment to claim 11.
Disclaimer
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 (i.e., changing from AIA to pre-AIA ) 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.

Intended use language is located in the preamble of claim 11 (apparatus for manufacturing an anode for an all-solid-state battery ). A preamble is generally not accorded any patentable weight where it merely recites the purpose of a process or the intended use of a structure, and where the body of the claim does not depend on the preamble for completeness but, instead, the process steps or structural limitations are able to stand alone. See In re Hirao, 535 F.2d 67, 190 USPQ 15 (CCPA 1976) and Kropa v. Robie, 187 F.2d 150, 152, 88 USPQ 478, 481 (CCPA 1951). Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) are capable of performing these intended uses and as a result meets the claim limitations.
Regarding claim 11, the Applicant claims a specific material or article worked upon including “an anode for an all-solid-state battery”. The substrate is not being given patentable weight in the coating apparatus.
The coating apparatus in Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) would be capable of coating this substrate. Inclusion of material or article worked upon by a structure being claimed does not impart patentability to the claims. In re Young, 75 F.2d 966, 25 USPQ 69 (CCPA 1935) (as restated in In re Otto, 312 F.2d 937, 136 USPQ 458, 459 (CCPA 1963)).
The recitation “for manufacturing …” merely recites an intended use of the apparatus and thus does not further structurally limit the apparatus as claimed. See MPEP 2114. However, it is wholly expected that the apparatus of the Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1), is fully capable of combining components (i.e. ) with various liquid compositions since the Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1 disclose every structural limitation of the claimed invention
Claim 11 recites an intended use clause (i. e. second coating member by applying voltages to the first coating member, first coating member is coated to the current collector, first or second coating member is installed to be movable in an up and down direction, ). A recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) are capable of performing these intended uses and as a result meets the claim limitations.
Examiner is considering the claimed limitation to be intended use and Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1), to meet the claimed limitation of “An apparatus for manufacturing an anode for an all-solid-state battery, comprising: a container in which a coating slurry comprising … a solvent is accommodated ” .
The Applicant claims a specific material or article worked upon including “a container in which a coating slurry comprising … a solvent is accommodated ”. The substrate is not being given patentable weight in the coating apparatus.
Third, the apparatus in Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1), would be capable of containing an amount of solvent. Inclusion of material or article worked upon by a structure being claimed does not impart patentability to the claims. In re Young, 75 F.2d 966, 25 USPQ 69 (CCPA 1935) (as restated in In re Otto, 312 F.2d 937, 136 USPQ 458, 459 (CCPA 1963)).
The recitation “a container in which a coating slurry comprising … a solvent is accommodated merely recites an intended use of the apparatus and thus does not further structurally limit the apparatus as claimed. See MPEP 2114. However, it is wholly expected that the apparatus of the Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1), is fully capable of combining components with various compositions.
Regarding claim 14, Tanaka is silent to the first coating member is a rotatably installed coating roll, and the coating slurry is attached to the surface of the first coating member by the coating roll that is rotated above the container.
Fukumoto provides the first coating member (13) is a rotatably installed coating roll, and the coating slurry (15) is attached to the surface of the first coating member by the coating roll that is rotated above the container (16). (See Fukumoto, Fig. 1, Abstract and paragraphs 11, 30-35, 44, 64, 86, and 105-107.)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to include the first coating member is a rotatably installed coating roll, and the coating slurry is attached to the surface of the first coating member by the coating roll that is rotated above the container, because Fukumoto teaches this structure allows the coating material to be transported to the substrate. (See Fukumoto, Fig. 1, Abstract and paragraphs 11, 30-35, 44, 64, 86, and 105-107.)
Regarding claim 20, Tanaka does not explicitly teach the coating slurry is coated to the current collector by moving in a direction opposite to gravity from the first coating member.
Fukumoto provides the coating slurry (15) is coated to the current collector (electrode sheet 14) by moving in a direction opposite to gravity from the first coating member (13). (See Fukumoto, Fig. 1, Abstract and paragraphs 11, 30-35, 44, 64, 86, and 105-107.)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to include the coating slurry is coated to the current collector by moving in a direction opposite to gravity from the first coating member, because Fukumoto teaches this structure allows the coating material to be precisely controlled and thin coating film to be applied. (See Fukumoto, Fig. 1, Abstract and paragraphs 11, 30-35, 44, 64, 86, and 105-107.)
The previous rejection of claim 12 under 35 U.S.C. 103 as being unpatentable over Yukiko Tanaka (US 20200168889 A1) in view of and Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) as applied to claim 11 and further in view of Leonard et al. (US 20040187773 A1) is withdrawn based on the cancellation of claim 12.
The previous rejection of claim 15 under 35 U.S.C. 103 as being unpatentable over Yukiko Tanaka (US 20200168889 A1) in view of and Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) as applied to claim 14 and further in view of Shiba et al (US 20170095830 A1) is withdrawn based on the amendment of claim 11.
Claim 15 is rejected under 35 U.S.C. 103 as being unpatentable over Yukiko Tanaka (US 20200168889 A1) in view of and Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Leonard et al. (US 20040187773 A1) and Heyl et al. (US 3,332,395 A1) Hayashi et al (US 20100062146 A1) as applied to claim 14 and further in view of Shiba et al (US 20170095830 A1).
Regarding claim 15, Tanaka is silent to the coating roll comprises at least one groove on a surface thereof.
Hayashi provides the coating roll comprises at least one groove on a surface thereof. (See Hayashi, Fig. 1, Abstract and paragraphs, 40-43, 58-61.)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to include the coating roll comprises at least one groove on a surface thereof, because Hayashi teaches this structure allows the coating material to be transported to the substrate. (See Hayashi, Fig. 1, Abstract and paragraphs 58-61.)
Regarding claim 15, Tanaka is silent to the groove having a predetermined width.
Shiba teaches a coating roller with grooves where the volume of the coating material carried by the groove is controlled.
Shiba teaches the desired amount of coating material can be applied with a gravure roller by setting the conditions of the volume of the grooves. (See Shiba, Fig. 1, Abstract and paragraphs, 11-13, 62, 64, 88-94, 126, 129, 131, and 142.)
It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to include the groove having a predetermined width, because Shiba teaches this would allow the volume of the grooves to be controlled and the amount of coating material applied by the roller on the substrate. (See Shiba, Fig. 1, Abstract and paragraphs, 11-13, 62, 64, 88-94, 126, 129, 131, and 142.)
The previous rejection of claim 16 under 35 U.S.C. 103 as being unpatentable over Yukiko Tanaka (US 20200168889 A1) in view of and Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) as applied to claim 11 and further in view of Shiba et al (US 20170095830 A1) is withdrawn based on the amendment to claim 11.
Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over YukikoTanaka (US 20200168889 A1) in view of and Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) and Leonard et al. (US 20040187773 A1) and Heyl et al. (US 3,332,395 A1) as applied to claim 11 and further in view of Shiba et al (US 20170095830 A1).
Regarding claim 16, Tanaka is silent to the transfer unit comprises transferring rolls that are installed respectively at an inlet side and an outlet side of the first and second coating members.

Intended use language is located in the preamble of claim 11 (apparatus for manufacturing an anode for an all-solid-state battery ). A preamble is generally not accorded any patentable weight where it merely recites the purpose of a process or the intended use of a structure, and where the body of the claim does not depend on the preamble for completeness but, instead, the process steps or structural limitations are able to stand alone. See In re Hirao, 535 F.2d 67, 190 USPQ 15 (CCPA 1976) and Kropa v. Robie, 187 F.2d 150, 152, 88 USPQ 478, 481 (CCPA 1951). Tanaka (US 20200168889 A1) in view of Fukumoto et al (US 20060248710 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) are capable of performing these intended uses and as a result meets the claim limitations.
Regarding claim 11, the Applicant claims a specific material or article worked upon including “an anode for an all-solid-state battery”. The substrate is not being given patentable weight in the coating apparatus.

Inclusion of material or article worked upon by a structure being claimed does not impart patentability to the claims. In re Young, 75 F.2d 966, 25 USPQ 69 (CCPA 1935) (as restated in In re Otto, 312 F.2d 937, 136 USPQ 458, 459 (CCPA 1963)).
The recitation “for manufacturing …” merely recites an intended use of the apparatus and thus does not further structurally limit the apparatus as claimed. See MPEP 2114. However, it is wholly expected that the apparatus of the Fukumoto et al (US 20060248710 A1) in view of Tanaka (US 20200168889 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1), is fully capable of combining components (i.e. ) with various liquid compositions since the Fukumoto et al (US 20060248710 A1) in view of Tanaka (US 20200168889 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) disclose every structural limitation of the claimed invention
Claim 11 recites an intended use clause (i. e. second coating member by applying voltages to the first coating member, first coating member is coated to the current collector, first or second coating member is installed to be movable in an up and down direction, ). A recitation of the intended use of the claimed invention must result in a structural difference between the claimed invention and the prior art in order to patentably distinguish the claimed invention from the prior art. If the prior art structure is capable of performing the intended use, then it meets the claim. Fukumoto et al (US 20060248710 A1) in view of Tanaka (US 20200168889 A1) and Polaroid (US 5,152,838) and Hayashi et al (US 20100062146 A1) are capable of performing these intended uses and as a result meets the claim limitations.

Inclusion of material or article worked upon by a structure being claimed does not impart patentability to the claims. In re Young, 75 F.2d 966, 25 USPQ 69 (CCPA 1935) (as restated in In re Otto, 312 F.2d 937, 136 USPQ 458, 459 (CCPA 1963)).
The recitation “a container in which a coating slurry comprising … a solvent is accommodated merely recites an intended use of the apparatus and thus does not further structurally limit the apparatus as claimed. See MPEP 2114.
