DETAILED ACTION
Summary
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Currently claims 1-19 are pending for examination.
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 1-19 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 1 uses the terms “first yarn feed” and “second yarn feed”. The limitation is indefinite because a “yarn feed” typically refers to how the yarn moves from its source to the product, and thus references a process or apparatus. It is therefore unclear what structure a yarn feed provides to the final product. For the purposes of examination “first yarn feed” and “second yarn feed” will be interpreted as a first yarn and a second yarn, respectively.
Claim 1 also recites “a first yarn feed and a second yarn feed in stitched relation through a stitched portion of the stitching substrate” in lines 4-5. The limitation is indefinite because it is unclear what the yarns are stitched in relation to. For example it is unclear whether the first yarn feed and the second yarn feed are stitched in relation with each other, or whether the first yarn feed and second yarn feed are stitched in relation to the stitching substrate. For the purposes of examination the limitation will be interpreted as the first yarn and the second yarn are stitched through a stitched portion of the stitching substrate.
Claims 12 and 19 also recite the limitations “first yarn feed”, “second yarn feed”, and “in stitched relation” and thus are indefinite for the reasons presented with respect to claim 1 above.
Claims 2-11 and 13-18 are also rejected under 35 U.S.C. 112(b) for their dependency on claims 1 or 12, rejected above.
Claims 2 and 13 recite the limitation “wherein the stitching substrate comprises at least one layer of fiber fleece having a mass per unit area …”. Claims 2 and 13 depend from claims 1 and 12, respectively, which recite the cleaning pad comprises a stitching substrate comprising fleece in layered relation with at least one support layer in lines 2-3. It is therefore unclear whether the mass per unit area further limits the fleece recited in claim 1 as part of the stitching substrate, or whether claims 2 and 13 further requires the presence of a second fleece with the recited mass per unit area. For the purposes of examination the limitation of claims 2 and 13 will be interpreted as further limiting the fleece previously recited in claims 1 and 12.
Claim 3 recites the limitation “wherein the stitching substrate comprises at least one layer of fiber fleece disposed in sandwiched relation between support layer substrates. Claim 3 depends from claim 1 which recites the cleaning pad comprises a stitching substrate comprising fleece in layered relation with at least one support layer in lines 2-3. It is therefore unclear whether claim 3 is further limiting the previously recited fleece or is requiring another fleece in addition to the one recited in claim 1. For the purposes for examination the limitation of claim 3 will be interpreted as further limiting the fleece previously recited in claim 1.
Claims 4-6 use the term “first yarn feed” and are indefinite for the reasons presented with respect to claim 1 above.
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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 1 and 4-6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274).
With respect to claim 1, Wildeman teaches wipes having an arrangement of elements projecting in a predefined pattern across an active surface (paragraph [0002]) which may be attached to a support with or without a handle such as a mop head (paragraph [0005]). Wildeman further teaches that stitch bonding is a well-known technique for forming fabrics with a uniform surface covered with stitching yarns (paragraph [0004]) and is suitable for forming arrays of loops on a sheet cleaning element (paragraph [0006]). The substrate material may be a fleece (paragraph [0037]) and may include combinations of materials, such as an upper layer (support layer) and a lower layer (paragraph [0070]).
Wildeman is silent as to the wipe having a first loop collection and a second loop collection wherein the second loop collection has an average pile height greater than the first loop collection.
Nordin teaches a cleaning cloth for cleaning dirty surfaces and a mop on which said cleaning cloth is arranged (col. 1, lines 5-7). The cleaning cloth is characterized by a base fabric having on one side longer loops of yarn with a normal fiber fineness (second loop collection) and shorter loops of microfilament yarn having great dirt and absorption ability (first loop collection) (col. 1, lines 47-55). The ratio between shorter loops (first loop collection) and longer loops (second loop collection) on one side of the cloth should be such that 75%-25%, preferably 50% are made up by the shorter loops (first loop collection) (col. 1, lines 65-67). When the side of the cloth having different lengths of loops is pulled over a surface, the longer loops (second loop collection) will have a brushing or sweeping effect and the shorter loops (first loop collection) will have an absorbing and accumulating effect on dust particles and humidity on the wiped surface (col. 3, lines 5-10).
The coverage area of the loops range of Nordin substantially overlaps the claimed range in the instant claim 1. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Morin, because overlapping ranges have been held to establish prima facie obviousness.
Since both Wildeman and Nordin teach wipes with piles used as cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the loops of Wildeman to comprise longer loops (second loop collection) and shorter loops (first loop collection) as described by Nordin in order to provide a wipe that brushes and sweeps as well as absorbs dust and humidity.
With respect to claim 4, Wildeman in view of Nordin teaches all the limitations of claim 1 above. Wildeman further teaches zones of different loop character may be arranged in a generally zigzag configuration (paragraph [0065]). With respect to whether the longer loops (second loop collection) or shorter loops (first loop collection) are stitched in the zigzag, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try the longer loops (second loop collection) and shorter loops (first loop collection) in the zigzag in order to determine which provides the desired cleaning properties. See MPEP 2143.
With respect to claims 5-6, Wildeman in view of Nordin teaches all the limitations of claim 1 above. Nordin further teaches the ratio between shorter loops (first yarn) and longer loops (second yarn) on one side of the cloth should be such that 75%-25%, preferably 50% are made up by the shorter loops (first yarn) (col. 1, lines 65-67).
Claim(s) 2 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) as applied to claim 1 above, and further in view of Takabayashi (US 2002/0065012).
With respect to claim 2, Wildeman in view of Nordin teaches all the limitations of claim 1 above.
Wildeman in view of Nordin is silent as to the fleece having a mass per unit area of 100 to 400 grams per square meter.
Takabayashi teaches a cleaning sheet that has excellent cleaning performance (paragraph [0009]-[0010]). The cleaning area of the cleaning sheet comprises a first sheet disposed on a second sheet, where the second sheet supports the first sheet (paragraph [0025]). The first sheet is an airlaid fabric (paragraph [0026]) which has a basis weight of 10-500 gsm, particularly 20-200 gsm (paragraph [0032]). A basis weight of more than 500 gsm is costly and unfit for high-speed production and a basis weight of less than 10 gsm is difficult to make and tends to have difficulty raking dust (paragraph [0032]).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the basis weight of the fleece of Wildeman in view of Nordin to include the claimed range. One would have been motivated to provide a fleece that is cheaper, easy to make, suitable for high-speed production, and allows dust collection. 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. See MPEP 2144.05(II).
Claim(s) 3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) as applied to claim 1 above, and further in view of Laun (US 6087279).
With respect to claim 3, Wildeman in view of Nordin teaches all the limitations of claim 1 above.
Wildeman in view of Nordin is silent as to the fleece being sandwiched between support layer substrates.
Laun teaches a surface-area material for used for cleaning (col. 1, lines 24-26) that may be used with a long-handled scrubbers (col. 1, lines 51-53). The surface-area material may have at least two non-woven materials reinforced with a support material (col. 1, lines 60-65). The support materials can be used to reinforce the products, to improve their resistance to tearing, and to improve shape stability during use (col. 1, lines 66 – col. 2, line 1). The support materials may overlay the non-woven material (col. 2, lines 1-4).
Since both Wildeman in view of Nordin and Laun teach cleaning fabrics suitable for use with long-handled scrubbers, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the wipe of Wildeman in view of Nordin to include a support layer overlaying the fleece in order to provide reinforcement to the wipe, improve the resistance to tearing, and to improve shape stability. With respect to the orientation of the layers, it further would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try the different possible orientations of the fleece, upper layer, and support layer, including the fleece being sandwiched between the upper layer and the support layer, in order to determine which orientation provides the desired strength and cleaning ability.
Claim(s) 7 and 10-11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) as applied to claim 1 above, and further in view of Morin (US 2004/0102119).
With respect to claim 7, Wildeman in view of Nordin teaches all the limitations of claim 1 above.
Wildeman in view of Nordin is silent as to the shorter loops (first loop collection) having a height in the range of about 1.5-3.5 mm.
Morin teaches textiles having loops extending outwardly from a base material (paragraph [0002]) and that loop textiles have many uses such as for cleaning purposes. The base substrate 100 may be knit, woven, non-woven, or any other similar web-like materials (paragraph [0010]). The base substrate 100 may include receiving loops 210, 220 and stiff loops 310, 320 (paragraphs [0010]-[0011], [0013]). The receiving loops and the stiff loops were added by knitting the filaments into the substrate and forming the loops (paragraphs [0027]-[0028]). The height of the receiving loop 210, 220 is between about 0.1 mm and about 5 mm, preferably between about 0.3 mm and about 3 mm, particularly about 0.8 mm (paragraph [0011]). The height of the stiff loop 310, 320 is between about 0.1 mm and about 5 mm, preferably between about 0.3 mm and about 3 mm, particularly about 1 mm (paragraph [0013]).
The receiving loops 210, 210 (first loop collection) height range of Morin substantially overlaps the claimed range in the instant claim 7. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Morin, because overlapping ranges have been held to establish prima facie obviousness.
Since both Wildeman in view of Nordin and Morin teach loop pile fabrics for cleaning, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the shorter loops (first loop collection) to have a height of between about 0.1 mm to about 5 mm, preferably between about 0.3 mm and about 3 mm, because it is known in the art as a suitable height for a loop textile cleaning article, and would yield the predictable result of a loop textile suitable for cleaning and scrubbing surfaces. See MPEP 2143.
With respect to claims 10-11, Wildeman in view of Nordin teaches all the limitations of claim 1 above.
Wildeman in view of Nordin is silent as to the longer loops (second loop collection) having an average yarn density in the range of 2-5 times the average yarn density of the loops forming the shorter loops (first loop collection).
Morin teaches textiles having loops extending outwardly from a base material (paragraph [0002]) and that loop textiles have many uses such as for cleaning purposes. The base substrate 100 may be knit, woven, non-woven, or any other similar web-like materials (paragraph [0010]). The base substrate 100 may include receiving loops 210, 220 and stiff loops 310, 320 (paragraphs [0010]-[0011], [0013]). The height of the receiving loop 210, 220 is particularly about 0.8 mm (paragraph [0011]). The height of the stiff loop 310, 320 is particularly about 1 mm (paragraph [0013]). The yarn forming the stiff loops 310, 320 can be stiffer than the material of the receiving loops 210, 220 by at least about 10 denier per filament (paragraph [0018]).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the yarn density of the longer loops (second loop collection) as compared to the shorter loops (first loop collection) to include the claimed range. One would have been motivated to provide longer loops (second loop collection) with the necessary stiffness suitable for the cleaning article. 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. See MPEP 2144.05(II).
Claim(s) 8-10 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) as applied to claim 1 above, and further in view of Winterling (DE 102007023335)1.
With respect to claims 8-9, Wildeman in view of Nordin teaches all the limitations of claim 1 above.
Wildeman in view of Nordin is silent as to the longer loops (second loop collection) having an average pile height at least 25-150% greater than the shorter loops (first loop collection).
Winterling teaches a wiping cloth and a wiping cover for a cleaning device which includes the wiping cloth (paragraph [0001]). The wiping cloth comprises at least two different pile fibers with different titers, and wherein the second pile fibers have a higher stiffness and a greater pile height than the first pile fibers (paragraph [0008]). Such a design, in particular the different pile height, achieves high cleaning performance and good absorption of liquids by the first pile fibers (paragraph [0009]). Because the second pile fibers are significantly taller than the first pile fibers, the surface to be cleaned is cleaned sufficiently well even with only slight pressure on the wiping cloth (paragraph [0010]) and the cleaning performance can be gradually adjusted to the degree of soiling of the surface to be cleaned (paragraph [0011]). The ratio of the pile height of the second pile fibers to the pile height of the first pile fibers is preferably 1.2 to 1.4 (20-40% greater), most preferably 1.3 (30% greater) (paragraph [0013]).
Since both Wildeman in view of Nordin and Winterling teach pile fabrics with two different pile heights for cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the longer loops (second loop collection) of Wildeman in view of Nordin to have a height that is 20-40% greater, preferably 30% greater, than the shorter loops (second loop collection) in order to provide a cleaning pile fabric which provides good cleaning performance that can be gradually adjusted to the degree of soiling of the surface to be cleaned.
With respect to claim 10, Wildeman in view of Nordin teaches all the limitations of claim 1 above.
Wildeman in view of Nordin is silent as to the longer loops (second loop collection) having a yarn density that is not less than 2 times the yarn density of the shorter loops (first loop collection).
Winterling teaches a wiping cloth and a wiping cover for a cleaning device which includes the wiping cloth (paragraph [0001]). The wiping cloth comprises at least two different pile fibers with different titers, and wherein the second pile fibers have a higher stiffness and a greater pile height than the first pile fibers (paragraph [0008]). Such a design, in particular the different pile height, achieves high cleaning performance and good absorption of liquids by the first pile fibers (paragraph [0009]). The ratio between the titer of the second pile fibers and the titer of the first pile fibers is preferably greater than 1000 (paragraph [0012]). This ratio achieves an excellent compromise between high cleaning performance of the first pile fibers and low friction of the second pile fibers (paragraph [0012]).
Since both Wildeman in view of Nordin and Winterling teach pile fabrics with two different pile heights for cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the longer loops (second loop collection) of Wildeman in view of Nordin to have a density that is greater than 1000 times greater than the shorter loops (second loop collection) in order to provide a cleaning pile fabric which provides an excellent compromise between high cleaning performance of the shorter loops (first loop collection) and low friction of the longer loops (second loop collection).
Claim(s) 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) and Laun (US 6087279).
With respect to claim 12, Wildeman teaches wipes having an arrangement of elements projecting in a predefined pattern across an active surface (paragraph [0002]) which may be attached to a support with or without a handle such as a mop head (paragraph [0005]). Wildeman further teaches that stitch bonding is a well-known technique for forming fabrics with a uniform surface covered with stitching yarns (paragraph [0004]) and is suitable for forming arrays of loops on a sheet cleaning element (paragraph [0006]). The substrate material may be a polyester fleece (paragraph [0037]) and may include combinations of materials, such as an upper layer (support layer) and a lower layer (paragraph [0070]).
Wildeman is silent as to the wipe having a first loop collection and a second loop collection wherein the second loop collection has an average pile height greater than the first loop collection.
Nordin teaches a cleaning cloth for cleaning dirty surfaces and a mop on which said cleaning cloth is arranged (col. 1, lines 5-7). The cleaning cloth is characterized by a base fabric having on one side longer loops of yarn with a normal fiber fineness (second loop collection) and shorter loops of microfilament yarn having great dirt and absorption ability (first loop collection) (col. 1, lines 47-55). The ratio between shorter loops (first loop collection) and longer loops (second loop collection) on one side of the cloth should be such that 75%-25%, preferably 50% are made up by the shorter loops (first loop collection) (col. 1, lines 65-67). When the side of the cloth having different lengths of loops is pulled over a surface, the longer loops (second loop collection) will have a brushing or sweeping effect and the shorter loops (first loop collection) will have an absorbing and accumulating effect on dust particles and humidity on the wiped surface (col. 3, lines 5-10).
The coverage area of the loops range of Nordin substantially overlaps the claimed range in the instant claim 12. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Morin, because overlapping ranges have been held to establish prima facie obviousness.
Since both Wildeman and Nordin teach wipes with piles used as cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the loops of Wildeman to comprise longer loops (second loop collection) and shorter loops (first loop collection) as described by Nordin in order to provide a wipe that brushes and sweeps as well as absorbs dust and humidity.
Wildeman further teaches zones of different loop character may be arranged in a generally zigzag configuration (paragraph [0065]). With respect to whether the longer loops (second loop collection) or shorter loops (first loop collection) are stitched in the zigzag, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try the longer loops (second loop collection) and shorter loops (first loop collection) in the zigzag in order to determine which provides the desired cleaning properties. See MPEP 2143.
Wildeman in view of Nordin is silent as to the fleece being sandwiched between support layer substrates.
Laun teaches a surface-area material for used for cleaning (col. 1, lines 24-26) that may be used with a long-handled scrubbers (col. 1, lines 51-53). The surface-area material may have at least two non-woven materials reinforced with a support material (col. 1, lines 60-65). The support materials can be used to reinforce the products, to improve their resistance to tearing, and to improve shape stability during use (col. 1, lines 66 – col. 2, line 1). The support materials may overlay the non-woven material (col. 2, lines 1-4).
Since both Wildeman in view of Nordin and Laun teach cleaning fabrics suitable for use with long-handled scrubbers, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the wipe of Wildeman in view of Nordin to include a support layer overlaying the fleece in order to provide reinforcement to the wipe, improve the resistance to tearing, and to improve shape stability. With respect to the orientation of the layers, it further would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try the different possible orientations of the fleece, upper layer, and support layer, including the fleece being sandwiched between the upper layer and the support layer, in order to determine which orientation provides the desired strength and cleaning ability.
Claim(s) 13 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) and Laun (US 6087279) as applied to claim 12 above, and further in view of Takabayashi (US 2002/0065012).
With respect to claim 13, Wildeman in view of Nordin and Laun teaches all the limitations of claim 12 above.
Wildeman in view of Nordin and Laun is silent as to the fleece having a mass per unit area of 100 to 400 grams per square meter.
Takabayashi teaches a cleaning sheet that has excellent cleaning performance (paragraph [0009]-[0010]). The cleaning area of the cleaning sheet comprises a first sheet disposed on a second sheet, where the second sheet supports the first sheet (paragraph [0025]). The first sheet is an airlaid fabric (paragraph [0026]) which has a basis weight of 10-500 gsm, particularly 20-200 gsm (paragraph [0032]). A basis weight of more than 500 gsm is costly and unfit for high-speed production and a basis weight of less than 10 gsm is difficult to make and tends to have difficulty raking dust (paragraph [0032]).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the basis weight of the fleece of Wildeman in view of Nordin and Laun to include the claimed range. One would have been motivated to provide a fleece that is cheaper, easy to make, suitable for high-speed production, and allows dust collection. 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. See MPEP 2144.05(II).
Claim(s) 14 and 17-18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) and Laun (US 6087279) as applied to claim 12 above, and further in view of Morin (US 2004/0102119).
With respect to claim 14, Wildeman in view of Nordin and Laun teaches all the limitations of claim 12 above.
Wildeman in view of Nordin and Laun is silent as to the shorter loops (first loop collection) having a height in the range of about 1.5-3.5 mm.
Morin teaches textiles having loops extending outwardly from a base material (paragraph [0002]) and that loop textiles have many uses such as for cleaning purposes. The base substrate 100 may be knit, woven, non-woven, or any other similar web-like materials (paragraph [0010]). The base substrate 100 may include receiving loops 210, 220 and stiff loops 310, 320 (paragraphs [0010]-[0011], [0013]). The receiving loops and the stiff loops were added by knitting the filaments into the substrate and forming the loops (paragraphs [0027]-[0028]). The height of the receiving loop 210, 220 is between about 0.1 mm and about 5 mm, preferably between about 0.3 mm and about 3 mm, particularly about 0.8 mm (paragraph [0011]). The height of the stiff loop 310, 320 is between about 0.1 mm and about 5 mm, preferably between about 0.3 mm and about 3 mm, particularly about 1 mm (paragraph [0013]).
The receiving loops 210, 210 (first loop collection) height range of Morin substantially overlaps the claimed range in the instant claim 7. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Morin, because overlapping ranges have been held to establish prima facie obviousness.
Since both Wildeman in view of Nordin and Laun and Morin teach loop pile fabrics for cleaning, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the shorter loops (first loop collection) to have a height of between about 0.1 mm to about 5 mm, preferably between about 0.3 mm and about 3 mm, because it is known in the art as a suitable height for a loop textile cleaning article, and would yield the predictable result of a loop textile suitable for cleaning and scrubbing surfaces. See MPEP 2143.
With respect to claims 17-18, Wildeman in view of Nordin and Laun teaches all the limitations of claim 1 above.
Wildeman in view of Nordin and Laun is silent as to the longer loops (second loop collection) having an average yarn density in the range of 2-5 times the average yarn density of the loops forming the shorter loops (first loop collection).
Morin teaches textiles having loops extending outwardly from a base material (paragraph [0002]) and that loop textiles have many uses such as for cleaning purposes. The base substrate 100 may be knit, woven, non-woven, or any other similar web-like materials (paragraph [0010]). The base substrate 100 may include receiving loops 210, 220 and stiff loops 310, 320 (paragraphs [0010]-[0011], [0013]). The height of the receiving loop 210, 220 is particularly about 0.8 mm (paragraph [0011]). The height of the stiff loop 310, 320 is particularly about 1 mm (paragraph [0013]). The yarn forming the stiff loops 310, 320 can be stiffer than the material of the receiving loops 210, 220 by at least about 10 denier per filament (paragraph [0018]).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the yarn density of the longer loops (second loop collection) as compared to the shorter loops (first loop collection) to include the claimed range. One would have been motivated to provide longer loops (second loop collection) with the necessary stiffness suitable for the cleaning article. 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.

Claim(s) 15-17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274) and Laun (US 6087279) as applied to claim 12 above, and further in view of Winterling (DE 102007023335)2.
With respect to claims 15-16, Wildeman in view of Nordin and Laun teaches all the limitations of claim 12 above.
Wildeman in view of Nordin and Laun is silent as to the longer loops (second loop collection) having an average pile height at least 50%, preferably 25-150%, greater than the shorter loops (first loop collection).
Winterling teaches a wiping cloth and a wiping cover for a cleaning device which includes the wiping cloth (paragraph [0001]). The wiping cloth comprises at least two different pile fibers with different titers, and wherein the second pile fibers have a higher stiffness and a greater pile height than the first pile fibers (paragraph [0008]). Such a design, in particular the different pile height, achieves high cleaning performance and good absorption of liquids by the first pile fibers (paragraph [0009]). Because the second pile fibers are significantly taller than the first pile fibers, the surface to be cleaned is cleaned sufficiently well even with only slight pressure on the wiping cloth (paragraph [0010]) and the cleaning performance can be gradually adjusted to the degree of soiling of the surface to be cleaned (paragraph [0011]). The ratio of the pile height of the second pile fibers to the pile height of the first pile fibers is preferably 1.2 to 1.4 (20-40% greater), most preferably 1.3 (30% greater) (paragraph [0013]).
Since both Wildeman in view of Nordin and Laun and Winterling teach pile fabrics with two different pile heights for cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the longer loops (second loop collection) of Wildeman in view of Nordin and Laun to have a height that is 20-40% greater, preferably 30% greater, than the shorter loops (second loop collection) in order to provide a cleaning pile fabric which provides good cleaning performance that can be gradually adjusted to the degree of soiling of the surface to be cleaned.
With respect to claim 17, Wildeman in view of Nordin and Laun teaches all the limitations of claim 12 above.
Wildeman in view of Nordin and Laun is silent as to the longer loops (second loop collection) having a yarn density that is not less than 2 times the yarn density of the shorter loops (first loop collection).
Winterling teaches a wiping cloth and a wiping cover for a cleaning device which includes the wiping cloth (paragraph [0001]). The wiping cloth comprises at least two different pile fibers with different titers, and wherein the second pile fibers have a higher stiffness and a greater pile height than the first pile fibers (paragraph [0008]). Such a design, in particular the different pile height, achieves high cleaning performance and good absorption of liquids by the first pile fibers (paragraph [0009]). The ratio between the titer of the second pile fibers and the titer of the first pile fibers is preferably greater than 1000 (paragraph [0012]). This ratio achieves an excellent compromise between high cleaning performance of the first pile fibers and low friction of the second pile fibers (paragraph [0012]).
Since both Wildeman in view of Nordin and Laun and Winterling teach pile fabrics with two different pile heights for cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the longer loops (second loop collection) of Wildeman in view of Nordin and Laun to have a density that is greater than 1000 times greater than the shorter loops (second loop collection) in order to provide a cleaning pile fabric which provides an excellent compromise between high cleaning performance of the shorter loops (first loop collection) and low friction of the longer loops (second loop collection).
Claim(s) 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Wildeman (US 2008/0250094) in view of Nordin (US 5804274), Laun (US 6087279), Takabayashi (US 2002/0065012), Morin (US 2004/0102119), and Winterling (DE 102007023335)3.
With respect to claim 19, Wildeman teaches wipes having an arrangement of elements projecting in a predefined pattern across an active surface (paragraph [0002]) which may be attached to a support with or without a handle such as a mop head (paragraph [0005]). Wildeman further teaches that stitch bonding is a well-known technique for forming fabrics with a uniform surface covered with stitching yarns (paragraph [0004]) and is suitable for forming arrays of loops on a sheet cleaning element (paragraph [0006]). The substrate material may be a polyester fleece (paragraph [0037]) and may include combinations of materials, such as an upper layer (support layer) and a lower layer (paragraph [0070]).
Wildeman is silent as to the wipe having a first loop collection and a second loop collection wherein the second loop collection has an average pile height greater than the first loop collection.
Nordin teaches a cleaning cloth for cleaning dirty surfaces and a mop on which said cleaning cloth is arranged (col. 1, lines 5-7). The cleaning cloth is characterized by a base fabric having on one side longer loops of yarn with a normal fiber fineness (second loop collection) and shorter loops of microfilament yarn having great dirt and absorption ability (first loop collection) (col. 1, lines 47-55). The ratio between shorter loops (first loop collection) and longer loops (second loop collection) on one side of the cloth should be such that 75%-25%, preferably 50% are made up by the shorter loops (first loop collection) (col. 1, lines 65-67). When the side of the cloth having different lengths of loops is pulled over a surface, the longer loops (second loop collection) will have a brushing or sweeping effect and the shorter loops (first loop collection) will have an absorbing and accumulating effect on dust particles and humidity on the wiped surface (col. 3, lines 5-10).
The coverage area of the loops range of Nordin substantially overlaps the claimed range in the instant claim 12. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Morin, because overlapping ranges have been held to establish prima facie obviousness.
Since both Wildeman and Nordin teach wipes with piles used as cleaning articles, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the loops of Wildeman to comprise longer loops (second loop collection) and shorter loops (first loop collection) as described by Nordin in order to provide a wipe that brushes and sweeps as well as absorbs dust and humidity.
Wildeman further teaches zones of different loop character may be arranged in a generally zigzag configuration (paragraph [0065]). With respect to whether the longer loops (second loop collection) or shorter loops (first loop collection) are stitched in the zigzag, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try the longer loops (second loop collection) and shorter loops (first loop collection) in the zigzag in order to determine which provides the desired cleaning properties. See MPEP 2143.
Wildeman in view of Nordin is silent as to the fleece being sandwiched between support layer substrates.
Laun teaches a surface-area material for used for cleaning (col. 1, lines 24-26) that may be used with a long-handled scrubbers (col. 1, lines 51-53). The surface-area material may have at least two non-woven materials reinforced with a support material (col. 1, lines 60-65). The support materials can be used to reinforce the products, to improve their resistance to tearing, and to improve shape stability during use (col. 1, lines 66 – col. 2, line 1). The support materials may overlay the non-woven material (col. 2, lines 1-4).
Since both Wildeman in view of Nordin and Laun teach cleaning fabrics suitable for use with long-handled scrubbers, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the wipe of Wildeman in view of Nordin to include a support layer overlaying the fleece in order to provide reinforcement to the wipe, improve the resistance to tearing, and to improve shape stability. With respect to the orientation of the layers, it further would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to try the different possible orientations of the fleece, upper layer, and support layer, including the fleece being sandwiched between the upper layer and the support layer, in order to determine which orientation provides the desired strength and cleaning ability.
Wildeman in view of Nordin and Laun is silent as to the fleece having a mass per unit area of 100 to 400 grams per square meter.
Takabayashi teaches a cleaning sheet that has excellent cleaning performance (paragraph [0009]-[0010]). The cleaning area of the cleaning sheet comprises a first sheet disposed on a second sheet, where the second sheet supports the first sheet (paragraph [0025]). The first sheet is an airlaid fabric (paragraph [0026]) which has a basis weight of 10-500 gsm, particularly 20-200 gsm (paragraph [0032]). A basis weight of more than 500 gsm is costly and unfit for high-speed production and a basis weight of less than 10 gsm is difficult to make and tends to have difficulty raking dust (paragraph [0032]).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the basis weight of the fleece of Wildeman in view of Nordin and Laun to include the claimed range. One would have been motivated to provide a fleece that is cheaper, easy to make, suitable for high-speed production, and allows dust collection. 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. See MPEP 2144.05(II).
Wildeman in view of Nordin, Laun, and Takabayashi is silent as to the shorter loops (first loop collection) having a height in the range of about 1.5-3.5 mm.
Morin teaches textiles having loops extending outwardly from a base material (paragraph [0002]) and that loop textiles have many uses such as for cleaning purposes. The base substrate 100 may be knit, woven, non-woven, or any other similar web-like materials (paragraph [0010]). The base substrate 100 may include receiving loops 210, 220 and stiff loops 310, 320 (paragraphs [0010]-[0011], [0013]). The receiving loops and the stiff loops were added by knitting the filaments into the substrate and forming the loops (paragraphs [0027]-[0028]). The height of the receiving loop 210, 220 is between about 0.1 mm and about 5 mm, preferably between about 0.3 mm and about 3 mm, particularly about 0.8 mm (paragraph [0011]). The height of the stiff loop 310, 320 is between about 0.1 mm and about 5 mm, preferably between about 0.3 mm and about 3 mm, particularly about 1 mm (paragraph [0013]).
The receiving loops 210, 210 (first loop collection) height range of Morin substantially overlaps the claimed range in the instant claim 7. It has been held that obviousness exists where the claimed ranges overlap or lie inside ranges disclosed by the prior art. See MPEP 2144.05 (I). Therefore, it would have been obvious to one of ordinary skill in the art at the time of the invention to have selected from the overlapping portion of the range taught by Morin, because overlapping ranges have been held to establish prima facie obviousness.
Since both Wildeman in view of Nordin, Laun, and Takabayashi and Morin teach loop pile fabrics for cleaning, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the shorter loops (first loop collection) to have a height of between about 0.1 mm to about 5 mm, preferably between about 0.3 mm and about 3 mm, because it is known in the art as a suitable height for a loop textile cleaning article, and would yield the predictable result of a loop textile suitable for cleaning and scrubbing surfaces. See MPEP 2143.
Wildeman in view of Nordin, Laun, Takabayashi, and Morin is silent as to the longer loops (second loop collection) having an average pile height at least 50% greater than the shorter loops (first loop collection).
Winterling teaches a wiping cloth and a wiping cover for a cleaning device which includes the wiping cloth (paragraph [0001]). The wiping cloth comprises at least two different pile fibers with different titers, and wherein the second pile fibers have a higher stiffness and a greater pile height than the first pile fibers (paragraph [0008]). Such a design, in particular the different pile height, achieves high cleaning performance and good absorption of liquids by the first pile fibers (paragraph [0009]).

The ratio of the pile height of the second pile fibers to the pile height of the first pile fibers is preferably 1.2 to 1.4 (20-40% greater), most preferably 1.3 (30% greater) (paragraph [0013]).
