DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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 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 1-14 are pending.
Claim Rejections - 35 USC § 112(a)/first paragraph
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(s) 1-14 is/are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, because the specification, while being enabling for certain embodiments, does not reasonably provide enablement for the full claimed scope. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to arrive at the invention in a manner commensurate in scope with the claims.
Upon review of the disclosure in its entirety, one having ordinary skill in the art would not be enabled to make the full scope of the invention as claimed without undue experimentation.
Claim 1 recites a viscosity property at 177 Celsius that only appears to be enabled for copolymers in the examples, while the claims are much broader (or unlimited) in various aspects with respect to the enabling examples. That is, the examples achieve the claimed viscosity property via copolymers with (1) certain repeating units (types of alkylene repeating units, and types of alkyl acrylate repeating units, whereas the claims are unlimited in this regard), (2) ratios of the respective three or four types of repeating units (whereas claim 1 is unlimited in this regard), and (3) polymerization conditions (see Table 1 in example 1, whereas the claims are unlimited in this regard). The claims are thus much broader than the enabling disclosure in the present specification, such that an undue amount of experimentation would be required by one of ordinary skill in the art to achieve claimed viscosity property across the full scope of the claimed invention (i.e., the embodiments of the claimed invention that are broader than the enabled examples, because there is no guidance in the present specification as to how to achieve the claimed viscosity property for these embodiments that are broader than the present examples and yet within the claimed scope).
Case law holds that applicant’s specification must be “commensurately enabling [regarding the scope of the claims]” Ex Parte Kung, 17 USPQ2d 1545, 1547 (Bd. Pat. App. Inter. 1990). Otherwise undue experimentation would be involved in determining how to practice and use applicant’s invention. The test for undue experimentation as to whether or not all embodiments within the scope of the claim can be made and/or used as claimed and whether the claim meets the test is stated in Ex parte Forman, 230 USPQ 546, 547 (Bd. Pat. App. Inter. 1986) and In re Wands, 8 USPQ2d 1400, 1404 (Fed.Cir. 1988).
Upon applying the Wands factors to claim 1, undue experimentation would be required:
(A) The breadth of the claims; (as explained above, the claims are broad in terms of the (1)-(3) aspects discussed above relative to the much narrower guidance provided in the specification)
(B) The nature of the invention; (C) The state of the prior art; (D) The level of one of ordinary skill; (the viscosity limitation as claimed would not be readily arrived at by one having ordinary skill in the art without significant guidance)
(E) The level of predictability in the art; (to achieve the full scope of the claimed invention with the limited guidance provided in the specification would require testing various copolymers without any apparent predictability)
(F) The amount of direction provided by the inventor; (G) The existence of working examples; and (the direction in the specification is sufficient for the examples, without any corresponding direction provided for achieving the claimed viscosity property with the broader copolymers as claimed)
(H) The quantity of experimentation needed to make or use the invention based on the content of the disclosure. (based on the broader claimed scope compared to the limited guidance in the specification and the apparent lack of predictability, the quantity of experimentation would be unreasonable).
The rest of the rejected claims not specifically addressed above are rejected because they depend from one of the claims specifically addressed above and fail to resolve the above enablement problem.
Claim Rejections - 35 USC § 112(b)/second paragraph
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.
Claim(s) 4-6, and 14 is/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 pre-AIA the applicant regards as the invention.
Claims 4-6 and 14 refer to “alkyl acrylates” and yet the copolymer is previously recited with “acrylic” such that it is unclear if these are meant to be equivalent or different components of the copolymers.
The rest of the rejected claims not specifically addressed above are rejected because they depend from one of the claims specifically addressed above and therefore include the same indefiniteness issue(s) via their dependency.
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 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.
If this application currently names joint inventors: in considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
When something is indicated as being “obvious” this should be taken as shorthand for “prima facie obvious to one having ordinary skill in the art to which the claimed invention pertains before the effective filing date of the invention”.
When a range is indicated as overlapping a claimed range, unless otherwise noted, this should be taken as short hand to indicate that the claimed range is obvious in view of the overlapping range in the prior art as set forth in MPEP 2144.05, in the case where the claimed range “overlap or lie inside ranges disclosed by the prior art”, a prima facie case of obviousness exists, In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990).
Claim(s) 1-14 is/are rejected under 35 U.S.C. 103 as being unpatentable over Helmeke (U.S. 6,133,400).
Regarding claims 1-14, Helmeke teaches a reactive hot melt composition for bonding two substrates as in claim 13, comprising an overlapping amount of the polyols of claims 10 and 11 and an overlapping amount of the isocyanate of claim 9, and an overlapping amount of an ethylene butyl acrylate carbon monoxide terpolymer as in claims 6 and 8 (see abstract, col. 4, line 10-col. 7, line 20, and col. 12, line 25-40, showing an exemplified amount of isocyanate that overlaps the claimed range, with broader overlapping amounts also being obvious based on the stoichiometric ratio of hydroxyl groups to isocyanate groups, col. 8, lines 40-55). The composition is discloses as having an adjustable set time based on desired application conditions, such that optimization to within the range of claim 12 is obvious as an art-recognized result effective variable (col. 2, lines 60-70).
The composition is also disclosed as having an adjustable viscosity, such that the viscosity of each individual ingredient, each of which contributes to the overall viscosity, would have been obvious to adjust, including to the values within claims 2 and 3, as part of optimizing the viscosity for different hot melt adhesive applications (col. 10, line 60-col. 11, line 5). Although the viscosity measurement temperature is not disclosed, optimization for the temperatures of col. 11 would still inherently affect the viscosity at the claimed temperature condition (because viscosity is inversely dependent on temperature, such that optimizing the viscosity at a lower temperature range would still result in the viscosity at 177 Celsius also being optimized).
Furthermore, for hot melt adhesives, viscosity is considered a prima facie obvious general condition, absent evidence of criticality. See MPEP 2144.05 II A. Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. “[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or workable ranges by routine experimentation.” In reAller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955) (Claimed process which was performed at a temperature between 40°C and 80°C and an acid concentration between 25% and 70% was held to be prima facie obvious over a reference process which differed from the claims only in that the reference process was performed at a temperature of 100°C and an acid concentration of 10%.); see also Peterson, 315 F.3d at 1330, 65 USPQ2d at 1382 (“The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set of percentage ranges is the optimum combination of percentages.”); In reHoeschele, 406 F.2d 1403, 160 USPQ 809 (CCPA 1969) (Claimed elastomeric polyurethanes which fell within the broad scope of the references were held to be unpatentable thereover because, among other reasons, there was no evidence of the criticality of the claimed ranges of molecular weight or molar proportions.). For more recent cases applying this principle, see Merck & Co. Inc.v.Biocraft Lab. Inc., 874 F.2d 804, 809, 10 USPQ2d 1843, 1848 (Fed. Cir. 1989), cert. denied, 493 U.S. 975 (1989)(Claimed ratios were obvious as being reached by routine procedures and producing predictable results); In reKulling, 897 F.2d 1147, 1149, 14 USPQ2d 1056, 1058 (Fed. Cir. 1990)(Claimed amount of wash solution was found to be unpatentable as a matter of routine optimization in the pertinent art, further supported by the prior art disclosure of the need to avoid undue amounts of wash solution); and In re Geisler, 116 F.3d 1465, 1470, 43 USPQ2d 1362, 1366 (Fed. Cir. 1997)(Claims were unpatentable because appellants failed to submit evidence of criticality to demonstrate that that the wear resistance of the protective layer in the claimed thickness range of 50-100 Angstroms was “unexpectedly good”); Smith v. Nichols, 88 U.S. 112, 118-19 (1874) (a change in form, proportions, or degree “will not sustain a patent”); In re Williams, 36 F.2d 436, 438, 4 USPQ 237 (CCPA 1929) (“It is a settled principle of law that a mere carrying forward of an original patented conception involving only change of form, proportions, or degree, or the substitution of equivalents doing the same thing as the original invention, by substantially the same means, is not such an invention as will sustain a patent, even though the changes of the kind may produce better results than prior inventions.”). See also KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416, 82 USPQ2d 1385, 1395 (2007) (identifying “the need for caution in granting a patent based on the combination of elements found in the prior art.”).
The particular amount of repeating units of claim 4 is not disclosed but is likewise prima facie obvious given the general conditions (the disclosed types of repeating units as claimed) disclosed in Helmenke (see MPEP 2144.05 II A as discussed above).
The limitations of claims 5, 7 and 14 relate to aspects of the tetrapolymer but the tetrapolymer is still not required such that these are optional limitation provided that the prior art teaches the terpolymer embodiment (as explained above).
In light of the overlap between the claimed composition and that disclosed by the above reference, it would have been obvious to one of ordinary skill in the art to use a composition that is both disclosed by the prior art and is encompassed within the scope of the present claims, and thereby arrive at the claimed invention.
