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.
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:
“a receiving unit for receiving the floor cleaner” in claim 1, line 3 and claim 12, line 2 and corresponding to the structural element 32 which receives the cleaning head 12 of the floor cleaner 10, and a support arm 34 against which the handle 16 of the floor cleaner 10 rests as described in page 4, ll. 20-23. This limitation shall be constructed to cover the structure described in the specification and equivalents thereof of performing the claimed function;
“a suction apparatus to actively suck liquid from the floor cleaner” in claim 12, line 4;
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 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 12-13, 16-21, and 23 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 limitation “a suction apparatus to actively suck liquid from the floor cleaner” in claim 12, line 4 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. The specification is devoid of adequate structure to perform the claimed function. In particular, the specification merely states the claimed function of actively suck liquid from the floor cleaner is performed by the suction apparatus. There is no disclosure of any particular structure, either explicitly or inherently, to perform the actively sucking. The use of the term “suction apparatus” is not adequate structure for performing the actively suck liquid function because it does not describe a particular structure for performing the function. As would be recognized by those of ordinary skill in the art, there are many different ways to actively suck liquid. The specification does not provide sufficient details such that one of ordinary skill in the art would understand which mechanical structures perform(s) the claimed function.
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.
Claims 13, 16-21, and 23 depends on claim 12 and are therefore rejected accordingly under 35 USC 112(b).
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.
Claim 12-13, 16-21 and 23 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. As described above, the disclosure does not provide adequate structure to perform the claimed function of the suction apparatus to actively suck liquid from the floor cleaner. The specification does not demonstrate that applicant has made an invention that achieves the claimed function because the invention is not described with sufficient detail that one of ordinary skill in the art can reasonably conclude that the inventor had possession of the claimed invention.
Claims 13, 16-21, and 23 depends on claim 12 and are therefore rejected accordingly under 35 USC 112(a).
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.
Claims 1, 5, 8-13, 16, and 19-23 are rejected under 35 U.S.C. 103 as being unpatentable over Siegel (DE 102019109298) in view of Mezeli (GB 2278047) and Rod (US Patent No. 2,989,965).
Regarding claim 1, Siegel discloses: a dock (Figures 1-9 element 88 and see also paragraphs 0162 and 0215) for receiving a floor cleaner (element 10), the dock comprising:
a receiving unit (element 91) for receiving the floor cleaner (see paragraphs 0217-0218);
a reservoir (element 104/106) for containing liquid (see paragraph 0228 where the prior art discloses element 106 of element 104 has “fresh water” (liquid)); and
wherein the dock is arranged to feed the liquid from the reservoir into the floor cleaner and receive the same liquid from the floor cleaner, the liquid having been flushed through the floor cleaner (See figure 1 showing element 104 (reservoir) having the liquid (fresh water) being pumped via element 108 to the connection (element 102 and see also paragraph 0230) which element 102 is utilized as “a means of which a fluid-effective connection” with element 10 (floor cleaner) which is fluidly connected to element 44 in order to supply fresh water to the tank (element 28) of the floor cleaner (see paragraph 0226), see also element 32 (line) connecting the tank (element 28) that has received the fresh water (liquid) being flushed through the floor cleaner via a line (element 32) toward element 34 and being fluidly connected to a tank device (element 20) of the floor cleaner (see paragraph 0212), and see also paragraph 0238 where the prior art discloses element 88 (dock) comprises element 120 that the fluid from element 20 (tank device) can be “discharged” (see paragraph 0238) via element 48 (see paragraph 0244). Therefore, the dock is arranged to feed liquid from the reservoir (via elements 102/108) into the floor cleaner (via element 44), receive the same liquid from the floor cleaner (via elements 48/120), and the liquid having been flushed through the floor cleaner (via elements 28/32/34/20).).
However, Siegel appears to be silent wherein the dock comprises an agitation unit, wherein the agitation unit is arranged to agitate the liquid being fed into the floor cleaner, and wherein the dock is arranged such that the liquid flushed through the floor cleaner returns directly to the reservoir for containing liquid.
Mezeli is also concern in providing a station (Figures 1-3 and see also page 4, paragraph 0003) for receiving cleaners (element 31) comprising a reservoir (element 20) for containing a liquid (see page 4, paragraph 0004 where the prior art discloses element 20 containing a “cleaning fluid” (liquid) shown shaded diagonally as best shown in figure 1) and further comprising an agitation unit (element 21) and wherein the agitation unit is arranged to agitate the liquid (Per the claim interpretation above (pages 4-5), the agitation unit is interpreted to be “a pump that may be arranged to agitate the liquid being fed into the floor cleaner 10, for example by creating bubbles and/or ultrasonic vibrations within the liquid”, similarly the prior art discloses in page 3, paragraph 0005 where the prior art discloses “the agitation mean” is “an electrically powered air pump”, see also page 4, paragraph 0005 where the prior art discloses element 21 as “an electric air pump”, and see also page 1, paragraph 0004 where the prior art discloses utilizing the agitation means in order to pass “gas bubbles” through and agitates the cleaning liquid, thus the agitation unit is capable of being arranged to agitate the liquid, as recited.).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Mezeli to provide an agitation unit and wherein the agitation unit is arranged to agitate the liquid. The resultant combination would have the agitation unit of Mezeli now arranged in the dock along tube that connects the reservoir (element 104) to the connecter (element 102) of Siegel which would necessarily agitate the liquid being fed into the floor cleaner. One of ordinary skill in the art would recognize that having an agitation unit would necessarily provide the predictable result of agitating the cleaning liquid being fed to the floor cleaner in order for the agitated cleaning liquid to reach awkwardly accessible areas during operations, thus improving cleaning efficiency.
Furthermore, Siegel modified utilizes two reservoirs (elements 104/122) having a first reservoir (element 104/106) for receiving fresh water (see paragraphs 0227-0228) and a second reservoir (element 122) for receiving waste fluid (see paragraphs 0239-0240). However, Siegel modified appears to be silent wherein the dock is arranged such that the liquid flushed through the floor cleaner returns directly to the reservoir for containing liquid.
Rod is also concern in providing a dock (Figures 1-2 and see also col. 2, ll. 26-30) for removing contaminates (see col. 1, ll. 28-32), wherein the station comprises a receiving unit (element 14) and a single reservoir (element 12) for containing a liquid (element 18 and see also col. 2, ll. 45). Rod further teaches wherein the dock is arranged such that the liquid flushed returns directly to the reservoir for containing liquid (See figure 2 showing a circulating system that receives the liquid (element 18) in the single reservoir (element 12) which leaves (see arrows) through element 26/30, is filtered via element 32, and is recirculated via a pump (element 34 and see also col. 2, ll. 52) back to the single reservoir (element 12) via element 24) in order for the same liquid to be utilized again, thus the dock is necessarily arranged such that the liquid flushed returns directly to the reservoir for containing liquid.).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Rod wherein the dock is arranged such that the liquid flushed returns directly to the reservoir for containing liquid. One of ordinary skill in the art would understand that utilizing a single reservoir instead of two different reservoir for receiving a liquid would necessarily allow the dock to continue to function as intended in order to contain/supply the liquid while also providing the added feature of recirculating the same liquid without the additional steps of supplying fresh water into one reservoir and discharging waste water from the other reservoir, thus saving on water and increasing efficiency during operations. Therefore, giving that the Siegel modified discloses the same dock as recited, one of ordinary skill would find it obvious that the dock would necessarily be arranged such that the liquid flushed through the floor cleaner returns directly to the reservoir for containing liquid, as recited.
Regarding claim 5, Siegel modified discloses: the dock as claimed in claim 1, wherein the agitation unit is arranged to introduce bubbles into the liquid (As described above in the rejection of claim 1 (see page 12), the prior art of Mezeli discloses “the agitation mean” is “an electrically powered air pump” (see page 3, paragraph 0005), see also page 4, paragraph 0005 where the prior art discloses element 21 as “an electric air pump”, and see also page 1, paragraph 0004 where the prior art discloses utilizing the agitation means in order to pass “gas bubbles” through and agitates the cleaning liquid, thus the agitation unit is capable to introduce bubbles into the liquid, as recited.).
Regarding claim 8, Siegel modified discloses all the limitations of claim 1, but appears to be silent wherein the dock further comprising a filter, the filter arranged to filter liquid extracted from the floor cleaner.
Rod is also concern in providing a dock (Figures 1-2 and see also col. 2, ll. 26-30) for removing contaminates (see col. 1, ll. 28-32), wherein the station comprises a receiving unit (element 14) and a single reservoir (element 12) for containing a liquid (element 18 and see also col. 2, ll. 45). Rod further teaches wherein the dock further comprising a filter (element 32), the filter arranged to filter liquid (see col. 2, ll. 50-52).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Rod wherein the dock further comprising a filter, the filter arranged to filter liquid. One of ordinary skill in the art would recognize that having a filter would necessarily allow the user to remove any contaminates or debris from the used liquid, thus promoting cleanliness during operations. Therefore, giving that the Siegel modified discloses the same dock as recited, one of ordinary skill would find it obvious that the dock’s filter would necessarily be arranged to filter liquid extracted from the floor cleaner, as recited.
Regarding claim 9, Siegel modified discloses: the dock as claimed in claim 1, further comprising a charging unit (element 176), the charging unit arranged to charge a battery (element 84) of the floor cleaner received in the receiving unit (see figure 1 and see also paragraph 0286).
Regarding claim 10, Siegel modified discloses: the dock as claimed in claim 1, further comprising a cleaning fluid reservoir (element 170) for supplying cleaning fluid to the floor cleaner received in the receiving unit (see figure 1 and see also paragraphs 0281-0282).
Regarding claim 11, Siegel modified discloses: a method (Figures 1-9 element 88 and see also paragraphs 0162 and 0215) of cleaning a floor cleaner (element 10) comprising the steps of:
docking the floor cleaner with the dock as claimed in claim 1 (see rejection above of claim 1 (see pages 8-11)) such that the floor cleaner is received in the receiving unit of the dock (see figure 1 and see also paragraphs 0217-0218),
feeding liquid from the reservoir for containing liquid into the floor cleaner (see figure 1 showing element 104 (reservoir) having the liquid (fresh water) being pumped via element 108 to the connection (element 102 and see also paragraph 0230) which element 102 is utilized as “a means of which a fluid-effective connection” with element 10 (floor cleaner) which is fluidly connected to element 44 in order to supply fresh water to the tank (element 28) of the floor cleaner (see paragraph 0226)),
extracting liquid from the floor cleaner, such that the liquid flushes through the floor cleaner (see figure 1 element 32 (line) connecting the tank (element 28) that has received the fresh water (liquid) being flushed through the floor cleaner via a line (element 32) toward element 34 and being fluidly connected to a tank device (element 20) of the floor cleaner (see paragraph 0212), and see also paragraph 0238 where the prior art discloses element 88 (dock) comprises element 120 that the fluid from element 20 (tank device) can be “discharged” (see paragraph 0238) via element 48 (see paragraph 0244)..
Regarding claim 12, Siegel discloses: a dock (Figures 1-9 element 88 and see also paragraphs 0162 and 0215) for receiving a floor cleaner (element 10), the dock comprising:
a receiving unit (element 91) for receiving the floor cleaner (see paragraphs 0217-0218),
a reservoir (element 104/106) for containing liquid (see paragraph 0228 where the prior art discloses element 106 of element 104 has “fresh water” (liquid)), and
a suction apparatus (element 130) to actively suck the same liquid from the floor cleaner (see paragraph 0245);
wherein the dock is arranged to feed the liquid from the reservoir into the floor cleaner and receive the same liquid from the floor cleaner, the liquid having been flushed through the floor cleaner (See figure 1 showing element 104 (reservoir) having the liquid (fresh water) being pumped via element 108 to the connection (element 102 and see also paragraph 0230) which element 102 is utilized as “a means of which a fluid-effective connection” with element 10 (floor cleaner) which is fluidly connected to element 44 in order to supply fresh water to the tank (element 28) of the floor cleaner (see paragraph 0226), see also element 32 (line) connecting the tank (element 28) that has received the fresh water (liquid) being flushed through the floor cleaner via a line (element 32) toward element 34 and being fluidly connected to a tank device (element 20) of the floor cleaner (see paragraph 0212), and see also paragraph 0238 where the prior art discloses element 88 (dock) comprises element 120 that the fluid from element 20 (tank device) can be “discharged” (see paragraph 0238) via element 48 (see paragraph 0244). Therefore, the dock is arranged to feed liquid from the reservoir (via elements 102/108) into the floor cleaner (via element 44), receive the same liquid from the floor cleaner (via elements 48/120), and the liquid having been flushed through the floor cleaner (via elements 28/32/34/20).).
Furthermore, Siegel modified utilizes two reservoirs (elements 104/122) having a first reservoir (element 104/106) for receiving fresh water (see paragraphs 0227-0228) and a second reservoir (element 122) for receiving waste fluid (see paragraphs 0239-0240). However, Siegel appears to be silent wherein the dock is arranged such that the liquid flushed through the floor cleaner returns directly to the reservoir for containing the liquid and an agitation unit, the agitation unit is arranged to agitate the liquid being fed into the floor cleaner via an inlet.
Rod is also concern in providing a dock (Figures 1-2 and see also col. 2, ll. 26-30) for removing contaminates (see col. 1, ll. 28-32), wherein the station comprises a receiving unit (element 14) and a single reservoir (element 12) for containing a liquid (element 18 and see also col. 2, ll. 45). Rod further teaches wherein the dock is arranged such that the liquid flushed returns directly to the reservoir for containing liquid (See figure 2 showing a circulating system that receives the liquid (element 18) in the single reservoir (element 12) which leaves (see arrows) through element 26/30, is filtered via element 32, and is recirculated via a pump (element 34 and see also col. 2, ll. 52) back to the single reservoir (element 12) via element 24) in order for the same liquid to be utilized again, thus the dock is necessarily arranged such that the liquid flushed returns directly to the reservoir for containing liquid.).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Rod wherein the dock is arranged such that the liquid flushed returns directly to the reservoir for containing liquid. One of ordinary skill in the art would understand that utilizing a single reservoir instead of two different reservoir for receiving a liquid would necessarily allow the dock to continue to function as intended in order to contain/supply the liquid while also providing the added feature of recirculating the same liquid without the additional steps of supplying fresh water into one reservoir and discharging waste water from the other reservoir, thus saving on water and increasing efficiency during operations. Therefore, giving that the Siegel modified discloses the same dock as recited, one of ordinary skill would find it obvious that the dock would necessarily be arranged such that the liquid flushed through the floor cleaner returns directly to the reservoir for containing liquid, as recited.
However, Siegel modified appears to be silent wherein the dock comprises an agitation unit, the agitation unit is arranged to agitate the liquid being fed into the floor cleaner via an inlet.
Mezeli is also concern in providing a station (Figures 1-3 and see also page 4, paragraph 0003) for receiving cleaners (element 31) comprising a reservoir (element 20) for containing a liquid (see page 4, paragraph 0004 where the prior art discloses element 20 containing a “cleaning fluid” (liquid) shown shaded diagonally as best shown in figure 1) and further comprising an agitation unit (element 21), wherein the agitation unit is arranged to agitate the liquid (Per the claim interpretation above (pages 4-5), the agitation unit is interpreted to be “a pump that may be arranged to agitate the liquid being fed into the floor cleaner 10, for example by creating bubbles and/or ultrasonic vibrations within the liquid”, similarly the prior art discloses in page 3, paragraph 0005 where the prior art discloses “the agitation mean” is “an electrically powered air pump”, see also page 4, paragraph 0005 where the prior art discloses element 21 as “an electric air pump”, and see also page 1, paragraph 0004 where the prior art discloses utilizing the agitation means in order to pass “gas bubbles” through and agitates the cleaning liquid, thus the agitation unit is capable of being arranged to agitate the liquid, as recited.) being fed into the floor cleaner via an inlet (element 24/25).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Mezeli to provide comprises an agitation unit, the agitation unit is arranged to agitate the liquid being fed into the floor cleaner via an inlet. The resultant combination would have the agitation unit of Mezeli now arranged in the dock along tube that connects the reservoir (element 104) to the connecter (element 102) of Siegel which would necessarily agitate the liquid being fed into the floor cleaner. One of ordinary skill in the art would recognize that having an agitation unit would necessarily provide the predictable result of agitating the cleaning liquid being fed to the floor cleaner in order for the agitated cleaning liquid to reach awkwardly accessible areas during operations, thus improving cleaning efficiency.
Regarding claim 13, Siegel modified discloses: the dock as claimed in claim 12, further comprising a suction nozzle (element 48) which connects to the floor cleaner in order to facilitate the passage of liquid out of the floor cleaner (see paragraphs 0243-0244).
Regarding claim 16, Siegel modified discloses: the dock as claimed in claim 12, wherein the agitation unit is arranged to introduce bubbles into the liquid (As described above in the rejection of claim 12 (see pages 17-18), the prior art of Mezeli discloses “the agitation mean” is “an electrically powered air pump” (see page 3, paragraph 0005), see also page 4, paragraph 0005 where the prior art discloses element 21 as “an electric air pump”, and see also page 1, paragraph 0004 where the prior art discloses utilizing the agitation means in order to pass “gas bubbles” through and agitates the cleaning liquid, thus the agitation unit is capable to introduce bubbles into the liquid, as recited.).
Regarding claim 19, Siegel modified discloses all the limitations of claim 12, but appears to be silent wherein the dock further comprising a filter, the filter arranged to filter liquid extracted from the floor cleaner.
Rod is also concern in providing a dock (Figures 1-2 and see also col. 2, ll. 26-30) for removing contaminates (see col. 1, ll. 28-32), wherein the station comprises a receiving unit (element 14) and a single reservoir (element 12) for containing a liquid (element 18 and see also col. 2, ll. 45). Rod further teaches wherein the dock further comprising a filter (element 32), the filter arranged to filter liquid (see col. 2, ll. 50-52).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Rod wherein the dock further comprising a filter, the filter arranged to filter liquid. One of ordinary skill in the art would recognize that having a filter would necessarily allow the user to remove any contaminates or debris from the used liquid, thus promoting cleanliness during operations. Therefore, giving that the Siegel modified discloses the same dock as recited, one of ordinary skill would find it obvious that the dock’s filter would necessarily be arranged to filter liquid extracted from the floor cleaner, as recited.
Regarding claim 20, Siegel modified discloses: the dock as claimed in claim 12, further comprising a charging unit (element 176), the charging unit arranged to charge a battery (element 84) of the floor cleaner received in the receiving unit (see figure 1 and see also paragraph 0286).
Regarding claim 21, Siegel modified discloses: the dock as claimed in claim 12, further comprising a cleaning fluid reservoir (element 170) for supplying cleaning fluid to the floor cleaner received in the receiving unit (see figure 1 and see also paragraphs 0281-0282).
Regarding claim 22, Siegel modified discloses: the dock as claimed in claim 1, further comprising a fluid flow path (see figure 1 annotated below Detail A) configured to guide the liquid from the reservoir to the floor cleaner (see figure 1 and see also paragraph 0230), wherein the agitation unit is positioned in the fluid flow path at a location fluidly downstream from the reservoir (See rejection of claim 1 above, where the prior art of Siegel modified discloses having the agitation unit of Mezeli now arranged in the dock along tube that connects the reservoir (element 104) to the connecter (element 102) of Siegel, and see figure 1 annotated below showing the fluid path (Detail A) positioned downstream of a portion (right-side) from the reservoir, thus the prior art would necessarily have the agitation unit positioned in the fluid flow path at a location fluidly downstream from a portion of the reservoir.).

Regarding claim 23, Siegel modified discloses: the dock as claimed in claim 12, further comprising a fluid flow path (see figure 1 annotated above Detail A) configured to guide the liquid from the reservoir to the floor cleaner (see figure 1 and see also paragraph 0230), wherein the agitation unit is positioned in the fluid flow path at a location fluidly downstream from the reservoir (See rejection of claim 1 above, where the prior art of Siegel modified discloses having the agitation unit of Mezeli now arranged in the dock along tube that connects the reservoir (element 104) to the connecter (element 102) of Siegel, and see figure 1 annotated above showing the fluid path (Detail A) positioned downstream of a portion (right-side) from the reservoir, thus the prior art would necessarily have the agitation unit positioned in the fluid flow path at a location fluidly downstream from a portion of the reservoir.).
Claims 6 and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Siegel (DE 102019109298) in view of Mezeli (GB 2278047) and Rod (US Patent No. 2,989,965) as applied to claims 1 and 12 above, and further in view of Caitlin (US Patent No. 2,994,330).
Regarding claim 6, Siegel modified discloses all the limitations of claim 1, but appears to be silent wherein the agitation unit is arranged to introduce ultrasonic vibrations into the liquid.
Caitlin is also concern in providing a station (Figures 1-2 and see also col. 2, ll. 12-40) for receiving cleaners (elements 20/21), wherein the station comprises a reservoir (element 14) for containing a liquid (element 19 and see also col. 2, ll. 29-35), an agitation unit (element 82 and see also col. 4, ll. 42) and wherein the agitation unit is arranged to introduce ultrasonic vibrations into the liquid (see col. 4, ll. 42-46).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Caitlin to provide wherein the agitation unit is arranged to introduce ultrasonic vibrations into the liquid. One of ordinary skill in the art would recognize that having the agitation unit producing ultrasonic vibrations into the liquid would necessarily provide the predictable result of agitating the cleaning liquid being fed to the floor cleaner in order for the agitated cleaning liquid to reach awkwardly accessible areas during operations, thus improving cleaning efficiency.
Regarding claim 17, Siegel modified discloses all the limitations of claims 12 and 15, but appears to be silent wherein the agitation unit is arranged to introduce ultrasonic vibrations into the liquid.
Caitlin is also concern in providing a station (Figures 1-2 and see also col. 2, ll. 12-40) for receiving cleaners (elements 20/21), wherein the station comprises a reservoir (element 14) for containing a liquid (element 19 and see also col. 2, ll. 29-35), an agitation unit (element 82 and see also col. 4, ll. 42) and wherein the agitation unit is arranged to introduce ultrasonic vibrations into the liquid (see col. 4, ll. 42-46).

Claims 7 and 18 are rejected under 35 U.S.C. 103 as being unpatentable over Siegel (DE 102019109298) in view of Mezeli (GB 2278047) and Rod (US Patent No. 2,989,965) as applied to claims 1 and 12 above, and further in view Vorwerk (DE 202016104067).
Regarding claim 7, Siegel modified discloses all the limitations of claim 1, but appears to be silent wherein the dock further comprising a heater, the heater arranged to heat the liquid being fed into the floor cleaner.
Vorwerk is also concern in providing a dock (Figure element 1 and see also paragraph 0025) for receiving a floor cleaner (element 2), the dock comprising a receiving unit (element 18) for receiving the floor cleaner (see figure 2), a reservoir (element 3) for ) for containing a liquid (see paragraph 0029 where the prior art discloses element 3 is used for “storing fresh liquid”) and further comprising a heater (element 8 and see also paragraph 0032 where the prior art discloses element 8 as “a heating device”), the heater arranged to heat the liquid being fed into the floor cleaner (see paragraph 0032-0033).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Vorwerk to provide a heater, the heater arranged to heat the liquid being fed into the floor cleaner. One of ordinary skill in the art would recognize that having the heater heat the liquid would necessarily allow the dock to deliver warm liquid to the wet cleaning device in order for the wet cleaning device to use the warm liquid to clean a surface to be cleaned or to self-clean its Vorwerk (see paragraph 0012).
Regarding claim 18, Siegel modified discloses all the limitations of claim 12, but appears to be silent wherein the dock further comprising a heater, the heater arranged to heat the liquid being fed into the floor cleaner.
Vorwerk is also concern in providing a dock (Figure element 1 and see also paragraph 0025) for receiving a floor cleaner (element 2), the dock comprising a receiving unit (element 18) for receiving the floor cleaner (see figure 2), a reservoir (element 3) for ) for containing a liquid (see paragraph 0029 where the prior art discloses element 3 is used for “storing fresh liquid”) and further comprising a heater (element 8 and see also paragraph 0032 where the prior art discloses element 8 as “a heating device”), the heater arranged to heat the liquid being fed into the floor cleaner (see paragraph 0032-0033).
It would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed invention to have modified Siegel to incorporate the teachings of Vorwerk to provide a heater, the heater arranged to heat the liquid being fed into the floor cleaner. One of ordinary skill in the art would recognize that having the heater heat the liquid would necessarily allow the dock to deliver warm liquid to the wet cleaning device in order for the wet cleaning device to use the warm liquid to clean a surface to be cleaned or to self-clean its Vorwerk (see paragraph 0012).
Response to Arguments
Applicant's arguments filed 04/03/2026 have been fully considered but they are not persuasive.
On pages 5-6, of the “Remarks”, the applicant argues that the claim limitations of “suction apparatus” do not invoke 35 U.S.C. § 112(f) interpretation. The applicant argues:
In the field of floor cleaners and docks for floor cleaners, a 'suction apparatus' (or similarly a 'suction device') is a well-known element, having sufficient structure, and is readily understood by those skilled in the art. For example, U.S. Patent No. 11,937,765 discloses a docking station including a "suction device" and U.S. Patent No. 12,090,650 discloses a cleaning robot including a "suction apparatus." As such, at least the '765 and '650 patents evidence that a 'suction apparatus' (or similarly a 'suction device') is a well- known element having sufficient structure in this field.
In responding to the above-noted arguments, the Office action further notes that the term "suction apparatus" does not necessarily provide sufficient structure for one of ordinary skill in the art to determine what qualifies/constitutes or is needed as structure that performs the claimed function to actively suck liquid. See Office action, page 24. The Office action also notes that each of the listed U.S. Patents provides structural examples of what the suction apparatus/device can be (e.g., an intake flow path and a suction fan, etc.). See id.
The Applicant continues to disagree. Indeed, the '765 and '650 patents (noted above) provide examples of structure associated with a suction apparatus/device, which evidences that a "suction apparatus" is a term of art, recognizable by one of ordinary skill in the art in this field. Further it has been held that "[i]nformation which is well known in the art need not be described in detail in the specification." MPEP §2163.
Claims 12-14 and 16-21 stand rejected under 35 U.S.C. 112(a) and 112(b) for allegedly failing to comply with the written description requirement and being indefinite because the term "suction apparatus" is being treated under 35 U.S.C. 112(f), but the written description fails to disclose the corresponding structure, material, or acts for performing the claimed function. See Office action, pages 5-8.
Similar to the above, the Applicant asserts that one of ordinary skill in the art would readily understand the term "suction apparatus" in claim 12 to have a sufficiently definite and clear meaning as the name for structure (i.e., it is a term of art). Consequently, the applicant asserts that claim 12 is definite and does not run afoul of the written description requirement.
Accordingly, the Applicant requests withdrawal of the corresponding rejections set forth under 35 U.S.C. 112(a) and 112(b).
The examiner respectfully disagrees. The term “apparatus” have been determined to be generic placeholder (a term that is simply a substitute for the term "means") since there is no structural specific meaning (for example, the suction apparatus may be identified as a vacuum or suction cup or pump that produces suction). Secondly, the terms are modified by functional language (a suction apparatus to actively suck the same liquid from the floor cleaner. Lastly, there is no modification by sufficient structure, material, or acts for performing the claimed function (there is no known additional structure in the claim that performed the claimed function. Lastly, the listed patent examples provide a variety of examples of what the suction apparatus/device can be (U.S. Patent No. 11,937,765 discloses that the suction device may include an intake flow path and suction fan (see col. 9, ll. 4-10) and U.S. Patent No. 12,090,650 discloses that the suction apparatus is a suction channel (see col. 56, ll. 15-17)) and does not explicitly disclose that all suction apparatus have the exact same structure. Thus, arguments have been found unpersuasive and the claim interpretation and 112a/112b rejections are maintained.
Applicant’s arguments on pages 7-10 the newly presented limitations of the independent claims and new claims have been fully considered and address in the rejection above.
