Office Action

§103 §112
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 . 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. Claims 1, 2, 4 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 treatment of colorectal cancer (MC38), does not reasonably provide evidence for inhibiting liver metastasis of cancers in a subject. The specification does not enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention commensurate in scope with these claims. This is a scope of enablement rejection. While determine whether a specification is enabling, one considers whether the claimed invention provides sufficient guidance to make and use the invention, if not, whether an artisan would have required undue experimentation to make and use the claimed invention and whether working examples has been provided. When determining whether a specification meets the enablement requirements, some of the factors that need to be analyzed are: the breadth of the claims, the nature of the invention, the state of the prior art, the level of one of ordinary skill, the level of predictability in the art, the amount of direction provided by the inventor, the existence of working examples, and whether the quantity of any necessary experimentation to make or use the invention based on the content of the disclosure is "undue" (In re Wands, 858 F.2d 731, 737, 8 USPQ2d 1400, 1404 (Fed. Cir. 1988)). Claims 1, 2, 4, recite a method for inhibiting liver metastasis of cancer in a subject because when the coffee extract is administered then inherently the coffee extract administered will inherently inhibiting liver metastasis of cancer. Applicant notes in paragraph 26, that “In the present invention, the term "prevention" includes any action that inhibits or delays the metastasis and growth of cancer cells by administration of the composition”. Therefore, the claimed invention reads on prevention. The instant specification gives results for colon cancer but not the other cancers. Hence, one of ordinary skill in the prior art could recognize that “inhibiting liver metastasis of cancer” means that the subject will never experience any characteristics associated with cancer which is a very tall order. The amount of guidance present in the specification and the absence of data proves in and of itself that one cannot from only knowing the treatment of colon cancer does not occur by administration of the claimed composition, and the state of the prior art, Applicant is not enabled for inhibiting liver metastasis of cancer. Due to the large quantity of experimentation necessary to determine whether inhibiting liver metastasis of cancer could be prevented by the claimed composition of the instant invention and the lack of direction/guidance presented in the specification regarding the same, the absence of working examples which can clearly be assessed the complex nature of the invention, the state of the prior art which establishes inhibiting liver metastasis of cancer would create undue experimentation would be required of the skilled artisan to make and/or use the claimed invention in its full scope. Applicant provides in the specification only data for colon cancer treatment but not inhibiting liver metastasis of cancer. Furthermore, the other cancers have no data supporting them. 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. Claims 1, 2 and 4 are rejected under 35 U.S.C. 103 as being unpatentable over JP 11-127834 (newly cited). JP teaches that a coffee extract is known to be used to reduce the incidence of rectal cancer, see page 8. MPEP 2144.05, subsection II. II. ROUTINE OPTIMIZATION A. Optimization Within Prior Art Conditions or Through Routine Experimentation 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 re Aller, 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 re Hoeschele, 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, 10 USPQ2d 1843 (Fed. Cir.), cert. denied, 493 U.S. 975 (1989); In re Kulling, 897 F.2d 1147, 14 USPQ2d 1056 (Fed. Cir. 1990); and In re Geisler, 116 F.3d 1465, 43 USPQ2d 1362 (Fed. Cir. 1997); 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 (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 (2007) (identifying "the need for caution in granting a patent based on the combination of elements found in the prior art."). B. There Must Be an Articulated Rationale Supporting the Rejection In order to properly support a rejection on the basis that an invention is the result of "routine optimization", the examiner must make findings of relevant facts, and present the underpinning reasoning in sufficient detail. The articulated rationale must include an explanation of why it would have been routine optimization to arrive at the claimed invention and why a person of ordinary skill in the art would have had a reasonable expectation of success to formulate the claimed range. See In re Stepan, 868 F.3d 1342, 1346, 123 USPQ2d 1838, 1841 (Fed. Cir. 2017). See also In re Van Os, 844 F.3d 1359,1361,121 USPQ2d 1209, 1211 (Fed. Cir. 2017 ("Absent some articulated rationale, a finding that a combination of prior art would have been ‘common sense’ or ‘intuitive’ is no different than merely stating the combination ‘would have been obvious.’"); Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355, 1362, 119 USPQ2d 1822 (Fed. Cir. 2016) ("[R]eferences to ‘common sense’ … cannot be used as a wholesale substitute for reasoned analysis and evidentiary support … ."). The Supreme Court has clarified that an "obvious to try" line of reasoning may properly support an obviousness rejection. In In re Antonie, 559 F.2d 618, 195 USPQ 6 (CCPA 1977), the CCPA held that a particular parameter must first be recognized as a result-effective variable, i.e., a variable which achieves a recognized result, before the determination of the optimum or workable ranges of said variable might be characterized as routine experimentation, because "obvious to try" is not a valid rationale for an obviousness finding. However, in KSR International Co. v. Teleflex Inc., 550 U.S. 398 (2007), the Supreme Court held that "obvious to try" was a valid rationale for an obviousness finding, for example, when there is a "design need" or "market demand" and there are a "finite number" of solutions. 550 U.S. at 421 ("The same constricted analysis led the Court of Appeals to conclude, in error, that a patent claim cannot be proved obvious merely by showing that the combination of elements was ‘[o]bvious to try.’ ... When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under §103."). Thus, after KSR, the presence of a known result-effective variable would be one, but not the only, motivation for a person of ordinary skill in the art to experiment to reach another workable product or process. It would have been obvious to one having ordinary skill in the art to use the claimed amounts of coffee since clearly coffee is a result effective variable in JP. Note that it is inherent that the composition of coffee in JP is able to inhibit cancer metastasis, cancer growth and VCAM1 expression since coffee is coffee and the same active components are found in the coffee of JP. It would have been obvious to one having ordinary skill in the art to inhibit liver metastasis of rectal cancer because JP teaches that it is known that people who drink more than three cups of coffee a day are less likely to develop rectal cancer. By the action of administering the coffee extract of JP, the claimed activities and purposes of the method are inherently met since the same coffee as claimed is administered in JP. The declaration by Dr. Son has been carefully considered. In the declaration, it is not clear how showing a treatment for melanoma cancer and colon cancer provides evidence for treating the other cancers and inhibiting liver metastasis of cancer. There simply is no support for these other cancers.
