Patentability shall not be negated by the manner in which the invention was made. Claims 1-8, 15, and 16 are rejected under 35 U.S.C. 103 as being unpatentable over Iwamoto et al. (US PGPub 2017/0053780, Iwamoto hereinafter) in view of Hori et al. (US PGPub 2021/0364927, Hori hereinafter). Regarding claim 1, Iwamoto discloses a target supply device (Figs. 1-3, 5-7, 11-12, 15, 24, 31, 35, abstract, target generator 8A) comprising: a tank main body portion configured to contain a target substance (Figs. 1-3, 5-7, 11-12, 15, 24, 31, 35, paras. [0079], [0086]-[0092], tank 84A contains target material 270); an output portion configured to output the target substance (Figs. 1-3, 5-7, 11-12, 15, 24, 31, 35, paras. [0079], [0086]-[0092], nozzle 86A outputs target material 270 from nozzle head 82A); an intermediate portion located between the tank main body portion and the output portion (Figs. 1-3, 5-7, 9-12, 15, 24, 31, 35, paras. [0086], [0088]-[0091], [0201]-[0207], nozzle body 85A in third region AR3 is between the tank 84A and the nozzle head 82A); a first main heater configured to heat the tank main body portion (Figs. 1-3, 5-7, 9-12, 15, 24, 31, 35, paras. [0143], [0202]-[0207], [0292], first temperature adjuster 91C includes first heater 911C to heat the reservoir tank 84A); a first sub-heater configured to heat the output portion (Figs. 1-3, 5-7, 9-12, 15, 24, 31, 35, paras. [0086], [0088]-[0091], [0143], [0202]-[0207], [0292], fourth temperature adjuster 94C includes heater 941C heating area AR4 with nozzle head 82A); an intermediate portion heater configured to heat the intermediate portion (Figs. 1-3, 5-7, 9-12, 15, 24, 31, 35, paras. [0086], [0088]-[0091], [0143], [0202]-[0207], [0292], third temperature adjuster 93C includes heater 931C to heat nozzle body 85A in third region AR3); and a temperature control processor configured to perform temperature lowering control of the first main heater, the first sub-heater, and the intermediate portion heater after output of the target substance is stopped (Figs. 1-3, 5-7, 9-12, 14-15, 21, 24-26, 31-35, paras. [0064], [0137], [0143], [0147], [0189], [0200]-[0207], [0292]-[0293], target generating section 70C includes temperature adjusters 91C, 92C, 93C, and 94C to control the heaters when output of the jet 27A is stopped to lower the temperature of the target material 270), the temperature control processor setting, in the temperature lowering control, a temperature of the intermediate portion heater to a temperature while setting each of a temperature of the first main heater and a temperature of the first sub-heater to a temperature higher than the melting point of the target substance (Figs, 1-3, 5-7, 9-12, 14-15, 21, 24-35, paras. [0132], [0143], [0147], [0160]-[0161], [0189], [0200]-[0226], [0236]-[0240], the temperature adjusters 91C, 92C, 93C, and 94C are controlled to set the heaters 941C and 911C above the melting point temperature of target material 270). Iwamoto does not appear to explicitly describe setting the temperature of the intermediate portion heater to a temperature lower than a melting point of the target substance. Hori discloses setting the temperature of the intermediate portion to a temperature lower than a melting point of the target substance (Figs. 1-3, paras. [0098], [0147], chamber C2 is arranged to have a temperature lower than the melting point of the target substance). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have included setting the temperature of the intermediate portion to a temperature lower than a melting point of the target substance as taught by Hori as the temperature of the intermediate portion heater in the target supply device as taught by Iwamoto since including setting the temperature of the intermediate portion heater to a temperature lower than a melting point of the target substance is commonly used to control the temperature of the target material in the target supply device as desired to facilitate handling the target substance (Hori, paras. [0095], [0147]). Regarding claim 2, Iwamoto as modified by Hori discloses wherein, during a first predetermined period in the temperature lowering control, the temperature control processor maintains the temperature of the intermediate portion heater in a second temperature range lower than the melting point of the target substance (Iwamoto, Figs, 1-3, 5-7, 11-12, 14-15, 21, 24-35, paras. [0132], [0143], [0160]-[0161], [0200]-[0226], the temperature adjusters 91C, 92C, 93C, and 94C, and as modified by Hori, Figs. 1-3, paras. [0098], [0147], chamber C2 is arranged to have a temperature lower than the melting point of the target substance) while maintaining the temperature of the first main heater and the temperature of the first sub-heater in a first temperature range higher than the melting point of the target substance (Iwamoto, Figs, 1-3, 5-7, 11-12, 14-15, 21, 24-35, paras. [0132], [0143], [0160]-[0161], [0200]-[0226], the temperature adjusters 91C, 92C, 93C, and 94C are controlled to set the heaters 941C and 911C above the melting point temperature of target material 270). Regarding claim 3, although the first embodiment of Iwamoto as modified by Hori does not appear to explicitly describe wherein the first predetermined period is 10 minutes or longer, a further embodiment of Iwamoto discloses wherein the first predetermined period is 10 minutes or longer (Iwamoto, Fig. 14, para. [0161], a time period is ten minutes or longer). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have included optimizing the time period to obtain wherein the first predetermined period is 10 minutes or longer as taught by the further embodiment of Iwamoto as the length of the first predetermined period in the temperature lowering control in the target supply device as taught by Iwamoto as modified by Hori since including wherein the first predetermined period is 10 minutes or longer is commonly used to control the amount of dissolved oxygen and precipitation of metal oxide as desired (Iwamoto, paras. [0007], [0161]). Regarding claim 4, Iwamoto as modified by Hori discloses wherein the target substance is tin (Iwamoto, Figs. 1-3, 5-7, 11-12, 15, 24, 31, 35, paras. [0079], [0092], [0099], [0103], [0132], target material 270 is tin), and the first temperature range is a temperature range of 232°C or higher and 290°C or lower (Iwamoto, Figs, 1-3, 5-7, 11-12, 14-15, 21, 24-35, paras. [0132], [0138], [0143], [0160], [0200]-[0226], [0237], the temperature adjusters 91C, 92C, 93C, and 94C are controlled to set the heaters 941C and 911C above the melting point temperature of target material 270 in a range of 232°C to 290°C). Regarding claim 5, although Iwamoto as modified by Hori discloses wherein the target substance is tin (Iwamoto, Figs. 1-3, 5-7, 11-12, 15, 24, 31, 35, paras. [0079], [0092], [0099], [0103], [0132], target material 270 is tin) and discloses the second temperature range is a temperature range of less than a melting point (Iwamoto, Figs, 1-3, 5-7, 11-12, 15, 24-35, paras. [0132], [0143], [0200]-[0223], the temperature adjusters 91C, 92C, 93C, and 94C, and as modified by Hori, Figs. 1-3, paras. [0087], [0096], [0098], [0147], chamber C2 is arranged to have a temperature lower than the melting point of the target substance, which is 232°C), the first embodiment of Iwamoto as modified by Hori does not appear to explicitly describe wherein the second temperature range is a temperature range of 150°C or higher and 200°C or lower. However, a further embodiment of Iwamoto discloses wherein a second temperature range is a temperature range of 150°C or higher and 200°C or lower (para. [0145], a temperature range is below the melting point in the range of 20°C to 220°C. Because there is no allegation of criticality and no evidence demonstrating a difference across the range, the further embodiment of Iwamoto discloses the claimed range with sufficient specificity. See MPEP 2131.03, subsection II. ClearValue Inc. v. Pearl River Polymers Inc., 668 F.3d 1340, 101 USPQ2d 1773 (Fed. Cir. 2012)). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have included optimizing the second temperature range to a temperature range of 150°C or higher and 200°C or lower as taught by the further embodiment of Iwamoto as the second temperature range in the target supply device as taught by the first embodiment of Iwamoto as modified by Hori since including wherein a second temperature range is a temperature range of 150°C or higher and 200°C or lower is commonly used to facilitate precipitation of metal oxide (Iwamoto, para. [0145]). Regarding claim 6, although Iwamoto as modified by Hori discloses the second temperature range is a temperature range lower than the temperature of the first sub-heater (Iwamoto, Figs, 1-3, 5-7, 9-12, 14-15, 21, 24-35, paras.

[0087], [0096], [0098], [0147], chamber C2 is arranged to have a temperature lower than the melting point of the target substance, which is 232°C), the first embodiment of Iwamoto as modified by Hori does not appear to explicitly describe wherein the second temperature is a temperature range lower than the temperature of the first sub-heater by 100°C or more and 140°C or less. A further embodiment of Iwamoto discloses wherein a second temperature range is a temperature range lower than a temperature by 100°C or more and 140°C or less (para. [0145], a temperature range is below the melting point in the range of 20°C to 220°C. Because there is no allegation of criticality and no evidence demonstrating a difference across the range, the further embodiment of Iwamoto discloses the claimed range with sufficient specificity. See MPEP 2131.03, subsection II. ClearValue Inc. v. Pearl River Polymers Inc., 668 F.3d 1340, 101 USPQ2d 1773 (Fed. Cir. 2012)). It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have included optimizing the second temperature range lower than a temperature by 100°C or more and 140°C or less as taught by the further embodiment of Iwamoto as the second temperature range lower than the temperature of the first sub-heater in the target supply device as taught by the first embodiment of Iwamoto as modified by Hori since including wherein the second temperature is a temperature range lower than the temperature of the first sub-heater by 100°C or more and 140°C or less is commonly used to facilitate precipitation of metal oxide (Iwamoto, para. [0145]). Regarding claim 7, Iwamoto as modified by Hori discloses wherein the first temperature range is a temperature range lower than the temperature of the first main heater and the temperature of the first sub-heater when the target substance is output (Iwamoto, Figs, 1-3, 5-7, 8-12, 14-15, 21, 23-35, paras. [0064]-[0065], [0079], [0119]-[0121], [0132], [0138], [0143], [0150], [0160], [0194], [0200]-[0226], [0237], the temperature adjuster controls the temperature of the heaters 941C and 911C to be in a range lower than when the target droplet 27 is output at temperature TH in the range of 280° to 300°). Regarding claim 8, Iwamoto as modified by Hori discloses wherein the temperature control processor adjusts a temperature lowering rate of the intermediate portion heater (Iwamoto, Figs, 1-3, 5-7, 8-12, 15, 23-35, paras. [0064], [0086], [0088]-[0091], [0137], [0143], [0147], [0189], [0200]-[0207], [0218]-[0226], [0237]-[0239], [0292]-[0293], target generating section 70C includes temperature adjuster 93C that controls the temperature change of the third heater 931C).
