Claim Rejections - 35 USC § 103
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.
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.
Claim(s) 1-4, 7, 9-12, 15, 17-19, 22, and 24-26 are rejected under 35 U.S.C. 103 as being unpatentable over Sugita et al. (U.S. Pub. No. 2010/0024814; hereinafter: “Sugita”) in view of Curtis et al. (U.S. Pub. No. 2013/0213397; hereinafter: “Curtis”).
Regarding Claim 1, Sugita discloses a pharmaceutical drug delivery device comprising: a drug delivery device body (5; Fig. 1, 2); a fluid outlet nose cone (8; Fig. 1, 2, 9) attached to the drug delivery device body (Fig. 1, 2; ¶¶ 0025, 0026); a fluid jet ejection cartridge (1; Fig. 1-4B) containing a liquid pharmaceutical drug (¶¶ 0025, 0030, 0034, 0035, 0045-0050) is disposed in the drug delivery device body (Fig. 1, 2; ¶¶ 0025, 0030, 0034, 0035, 0045-0050), wherein a fluid jet ejection head (3; Fig. 1-3A, 4A) is attached to the fluid jet ejection cartridge (Fig. 1-3A, 4A; ¶¶ 0025, 0030, 0034, 0035, 0045-0050) and the fluid jet ejection head is in fluid flow communication with the fluid outlet nose cone (Fig. 1-3A, 4A; ¶¶ 0025, 0030, 0034, 0035, 0045-0050), the fluid jet ejection head capable of producing a spray of the liquid pharmaceutical drug on demand under ambient atmospheric pressure (¶¶ 0032, 0045-0050), wherein the fluid outlet nose cone comprises a plurality of air flow ports (11; Fig. 1, 2) open to an ambient atmosphere (¶¶ 0025, 0030).
Sugita does not specifically disclose the pharmaceutical drug delivery device wherein the plurality of air flow ports of the fluid outlet nose cone are a plurality of air flow channels open to an ambient atmosphere for providing a pressure differential between an inner area of the fluid outlet nose cone adjacent to the fluid ejection head and the ambient atmosphere.
Curtis teaches a substances deliver inhaler (400; Fig. 4-9) comprising a fluid outlet (404; Fig. 4, 8, 9) comprising a plurality of air flow channels (406, 410; Fig. 4, 5, 8, 9) open to an ambient atmosphere for providing a pressure differential between an inner area (408; Fig. 4, 5, 8, 9; ¶¶ 0135, 0141-0146) of the fluid outlet adjacent to a fluid ejection head (402; Fig. 4, 8, 9) and the ambient atmosphere (Fig. 4-9; ¶¶ 0135, 0141-0146) for the purpose of opening or closing the plurality of air flow channels thereby influencing flow rate through the device thus tuning the device to respond "optimally" to the needs of a patient (¶ 0146).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the pharmaceutical drug delivery device of Sugita to include the plurality of air flow ports of the fluid outlet nose cone to be the plurality of air flow channels open to the ambient atmosphere for providing a pressure differential between an inner area of the fluid outlet nose cone adjacent to the fluid ejection head and the ambient atmosphere as taught by Curtis for the purpose of opening or closing the plurality of air flow channels thereby influencing flow rate through the device thus tuning the device to respond "optimally" to the needs of a patient (See Curtis: ¶ 0146).
Regarding Claims 2, 10, and 18, the modified device of Sugita discloses the pharmaceutical drug delivery device of claim 1, shown above.
The modified device of Sugita discloses altering the plurality of air flow channels results in a change to the air flow rate (See Curtis: ¶¶ 0141-0146).
The modified device of Sugita does not explicitly disclose the pressure differential ranges from about 5 to about 10 kPa at an air flow rate of from about 50 to about 100 L/min.
The modified device of ALT discloses altering the plurality of air flow channels needs to be optimized to influence the flow rate to tune the device respond to the needs of a patient (See Curtis: ¶ 0146). As such the opening or closing/blocking of the plurality of air flow channels is disclosed to be a result effective variable in that opening or closing/blocking of the plurality of air flow channels effects the air flow rate and pressure differential. Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the modified device of Sugita to have the air flow rate and pressure differential within the claimed range, as it involves only adjusting the dimensions and/or opening or closing/blocking of a component disclosed to require adjustment.
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the modified device of Sugita by making the plurality of air flow channels opened or closed/blocked such that the pressure differential ranges from about 5 to about 10 kPa at an air flow rate of from about 50 to about 100 L/min as a matter of routine optimization since it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (See MPEP 2144.05).
Regarding Claims 3, 11, and 19, the modified device of Sugita discloses the pharmaceutical drug delivery device of claim 1, wherein the plurality of air flow channels are adjacent to an exterior surface (A, Fig. A annotated below) of the fluid outlet nose cone (See Curtis: ¶¶ 0141-0146).

Regarding Claims 4 and 12, the modified device of A Sugita LT discloses the pharmaceutical drug delivery device of claim 1, wherein the plurality of air flow channels extend along a long axis (B, Fig. A annotated above) of the fluid outlet nose cone (See Curtis: Fig. 4-9; ¶¶ 0141-0146).
Regarding Claims 7, 15, and 22, the modified device of Sugita discloses the pharmaceutical drug delivery device of claim 1, shown above.
The modified device of Sugita discloses altering the plurality of air flow channels results in a change to the air flow rate (See Curtis: ¶¶ 0141-0146).
The modified device of A Sugita LT does not explicitly disclose wherein the plurality of air flow channels have a combined air flow area ranging from about 8.0 to about 17.5 mm2.
The modified device of Sugita discloses altering the plurality of air flow channels needs to be optimized to influence the flow rate to tune the device respond to the needs of a patient (See Curtis: ¶¶ 0145, 0146). As such the opening or closing/blocking and/or setting of the diameter of the plurality of air flow channels is disclosed to be a result effective variable in that opening or closing/blocking and/or changing the diameter of the plurality of air flow channels effects the air flow rate. Further, it appears that one of ordinary skill in the art would have had a reasonable expectation of success in modifying the modified device of Sugita to have the air flow rate within the claimed range, as it involves only adjusting the dimensions and/or opening or closing/blocking of a component disclosed to require adjustment.
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to modify the modified device of Sugita by making the plurality of air flow channels opened or closed/blocked or altering their diameter such that the plurality of air flow channels have a combined air flow area ranging from about 8.0 to about 17.5 mm2 as a matter of routine optimization since it has been held that “where the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (See MPEP 2144.05).
Regarding Claim 9, Sugita discloses a method for reducing a pressure differential on a fluid jet ejection head for a nasal spray device (5, 8; Fig. 1, 2, 9; ¶¶ 0025, 0030, 0034, 0035, 0045-0050), the method comprising: providing a fluid outlet nose cone (8; Fig. 1, 2, 9) attached to a body (5; Fig. 1, 2) for the nasal spray device (Fig. 1-3A, 4A; ¶¶ 0025, 0030, 0034, 0035, 0045-0050); a fluid jet ejection cartridge (1; Fig. 1-4B) disposed in the body, the fluid jet ejection cartridge containing the fluid jet ejection head in fluid flow communication with the fluid outlet nose cone and a pharmaceutical drug in the fluid jet ejection cartridge (Fig. 1-3A, 4A; ¶¶ 0025, 0030, 0034, 0035, 0045-0050), the fluid jet ejection head capable of producing a spray of the liquid pharmaceutical drug on demand under ambient atmospheric pressure (¶¶ 0032, 0045-0050), providing a plurality of air flow ports (11; Fig. 1, 2) open to an ambient atmosphere (¶¶ 0025, 0030); and activating the nasal spray device when the fluid outlet nozzle is inserted into the nasal passage of a user (¶¶ 0025, 0030, 0034, 0035, 0045-0050).
Sugita does not specifically discloses the method wherein the plurality of air flow ports open to an ambient atmosphere comprises providing a plurality of air flow channels open to an ambient atmosphere for providing a pressure differential between an inner area of the fluid outlet nose cone adjacent to the fluid jet ejection head and the ambient atmosphere; and activating the nasal spray device while flowing air through the air flow channels when the fluid outlet nozzle is inserted into the nasal passage of a user thereby preventing fluid from drooling from the fluid jet ejection head upon inhalation by a user of the nasal spray device.
Curtis teaches a substances deliver method comprising a substances deliver device (400; Fig. 4-9) comprising a fluid outlet (404; Fig. 4, 8, 9) providing a plurality of air flow channels (406, 410; Fig. 4, 5, 8, 9) open to an ambient atmosphere for providing a pressure differential between an inner area (408; Fig. 4, 5, 8, 9; ¶¶ 0135, 0141-0146) of the fluid outlet adjacent to a fluid ejection head (402; Fig. 4, 8, 9) and the ambient atmosphere (Fig. 4-9; ¶¶ 0135, 0141-0146) and activating the device while flowing air through the air flow channels (¶¶ 0135, 0141-0146) thereby preventing fluid from drooling from the fluid ejection head upon inhalation by a user of the device (¶¶ 0135, 0141-0146) for the purpose of opening or closing the plurality of air flow channels thereby influencing flow rate through the device thus tuning the device to respond "optimally" to the needs of a patient (¶ 0146).
Therefore, it would have been obvious to one having ordinary skill in the art before the effective filing date of the invention to modify the method of ALT to include the plurality of air flow ports open to the ambient atmosphere comprises providing the plurality of air flow channels open to an ambient atmosphere for providing a pressure differential between an inner area of the fluid outlet nose cone adjacent to the fluid jet ejection head and the ambient atmosphere; and activating the nasal spray device while flowing air through the air flow channels when the fluid outlet nozzle is inserted into the nasal passage of a user thereby preventing fluid from drooling from the fluid jet ejection head upon inhalation by a user of the nasal spray device as taught by Curtis for the purpose of opening or closing the plurality of air flow channels thereby influencing flow rate through the device thus tuning the device to respond "optimally" to the needs of a patient (See Curtis: ¶ 0146).

Response to Arguments
Applicant’s arguments regarding the new limitations with respect to “the fluid jet ejection head capable of producing a spray of the liquid pharmaceutical drug on demand under ambient atmospheric pressure” as recited in independent claim 1 and 9 and similarly in independent claim 17 have been considered but are moot because the arguments do not apply to the rejection in the previous office action (e.g., do not apply to claim limitations previously rejected). All arguments directed to new limitations in the amended claims are addressed in the 35 U.S.C. 103 rejection Sugita in view of Curtis, shown above.
