Regarding Claim 9, Ma does not specifically disclose wherein the one or more fire extinguishing agents are biodegradable (See Description paragraph 4 “ultrafine dry powder” however such powder being biodegradable is not specifically disclosed).
However, Demmitt discloses, in the same field of endeavor, a fire suppression system (See Figs. 1-2) comprising an elongated housing (#20) that is biodegradable (See Paragraph 0033 disclosing corrugated cardboard) and one or more fire extinguishing agents that are biodegradable (See Paragraphs 0049-0050 of Demmitt disclosing “MAP” which is biodegradable per Paragraph 0046 of applicant’s Specification.).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the fire suppression system of Ma in view of Yang as applied to Claim 8 above such that the one or more fire extinguishing agents are biodegradable by utilizing the MAP material of Demmitt, since doing so would yield the predictable result of utilizing an environmentally friendly powder having no toxicity (See Demmitt Paragraph 0050).
As to Claim 10, in reference to the fire suppression system of Ma in view of Yang and Demmitt as applied to Claim 9 above, Ma does not specifically disclose wherein the housing is an elongated housing (See Fig. 1 showing a spherical housing).
However, Demmitt discloses a fire suppression system having a housing that is an elongated housing (See #20 in Fig. 1 and See Paragraph 0032 disclosing a cylindrical housing with a tail #30).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the fire suppression system of Ma in view of Yang and Demmitt as applied to Claim 9 above such that the housing is an elongated housing as taught by Demmitt, since doing so would yield the predictable result of helping the fire suppression apparatus maintain a vertical trajectory when aerially dropped on a target (See Demmitt Paragraphs 0032-0033).
As to Claim 11, in reference to the fire suppression system of Ma in view of Yang and Demmitt as applied to Claim 9 above, Demmitt further discloses wherein the one or more fire extinguishing agents are biodegradable fertilizers (See Demmitt Paragraph 0049 disclosing that MAP is a water-soluble fertilizer affective on all soils for forest restoration).
Claims 7 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Ma in view of Yang and US Patent 6,796,382 to Kaimart (“Kaimart”).
Regarding Claim 7, in reference to the fire suppression apparatus of Ma in view of Yang as applied to Claim 1 above, Ma does not disclose wherein the first housing and the second housing include a waterproof sealant, and
wherein the waterproof sealant is configured to melt due to the flame exposure, exposing the at least one trigger fuse to a fire.
However, Kaimart discloses, in the same field of endeavor, a fire suppression apparatus (See Fig. 1) comprising a housing (#3) that has a waterproof sealant (#2 along with additional application of silicone sealant, See Col. 4 Lines 12-33), wherein the waterproof sealant is configured to melt due to flame exposure, exposing at least one trigger fuse to a fire (See Fig. 1, See Col. 4 Lines 12-33 and See Col. 6 Lines 49-67. Since the wrap #2 is made of PVC plastic with silicone sealant, it is configured to melt when a flame is exposed, exposing trigger fuse #6 to a fire). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the fire suppression apparatus of Ma in view of Yang as applied to Claim 1 above to have the first housing and second housing of Ma covered with the PVC plastic wrap #2 of Kaimart along with silicone sealant of Kaimart since doing so would yield the predictable result of protecting the fire suppression apparatus from water exposure and surface abrasion (See Kaimart Col. 4 Lines 25-33). Making such a modification would result in the first housing and the second housing including a waterproof sealant such that the waterproof sealant is configured to melt due to the flame exposure, exposing portions of the at least one trigger fuse to a fire.
Regarding Claim 18, in reference to the method of Ma in view of Yang as applied to Claim 15 above, Ma does not disclose wherein ignition of the trigger fuse occurs after a waterproof element melts.
However, Kaimart discloses a method (See Fig. 1 and Col. 6 Lines 18-67) wherein ignition of a trigger fuse (#6) occurs after a waterproof element (#2 along with additional application of silicone sealant, See Col. 4 Lines 12-33) melts (See Fig. 1, See Col. 4 Lines 12-33 and See Col. 6 Lines 49-67. Since the wrap #2 is made of PVC plastic with silicone sealant, it will melt when a flame is exposed, subsequently exposing trigger fuse #6 to a fire). Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method of Ma in view of Yang as applied to Claim 15 above to have housings #12 of Ma covered with the PVC plastic wrap #2 of Kaimart along with silicone sealant of Kaimart since doing so would yield the predictable result of providing protection to water exposure and surface abrasion for a fire suppression apparatus (See Kaimart Col. 4 Lines 25-33). Making such a modification would result in ignition of at least a portion of the trigger fuse occurring after the waterproof element melts.
Claim 21 is rejected under 35 U.S.C. 103 as being unpatentable over Ma in view of Yang and US PGPUB 2005/0139363 A1 to Thomas (“Thomas”).
As to Claim 21, in reference to the method of Ma in view of Yang as applied to Claim 15 above, Ma further discloses wherein housing of the plurality of housings are linearly linked (See Figs. 1 and 3).
Regarding Claim 21, Ma does not specifically disclose wherein housings of the plurality of housings are linearly linked along a direction of elongation of the housings (See Figs. 1 and 3, the housings are spherical and not elongated).
However, Thomas discloses, in the same field of endeavor, a fire suppression system wherein housing are linearly linked along a direction of elongation of the housings (See Fig. 35 and See Paragraph 0260 disclosing a capsule being cylindrical).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the method of Ma in view of Yang as applied to Claim 15 above such that the plurality of housings are cylindrical and linearly linked along a direction of elongation of the housings, since doing so would yield the predictable result of having the housings shaped suitable to contain fire suppressant and appropriate for aerially dropping into a fire zone (See Thomas Paragraphs 0047-0047).
