`
`DETAILED ACTION
`
`1.
`
`The present application is being examined under the pre-AlA first to invent
`
`provisions.
`
`Information Disclosure Statement
`
`2.
`
`The information disclosure statement (IDS) submitted on 5/24/13 is
`
`acknowledged and has been reviewed.
`
`Double patenting Rejection

`
`Examiner acknowledges the filing of the terminal disclaimers.
`
`Claim Rejections - 35 USC § 103
`
`4.
`
`In the event the determination of the status of the application as subject to AlA 35
`
`U.S.C. 102 and 103 (or as subject to pre-AlA 35 U.S.C. 102 and 1 03) 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.
`
`The following is a quotation of pre-AlA 35 U.S.C. 1 03(a) which forms the basis
`
`for all obviousness rejections set forth in this Office action:
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described
`as set forth in section 1 02 of this title, if the differences between the subject matter sought to
`be patented and the prior art are such that the subject matter as a whole would have been
`obvious at the time the invention was made to a person having ordinary skill in the art to which
`said subject matter pertains. Patentability shall not be negatived by the manner in which the
`invention was made.
`
`The following is a quotation of pre-AlA 35 U.S.C. 1 03(a) which forms the basis
`
`for all obviousness rejections set forth in this Office action:

`
`Application/Control Number: 13/901 ,830
`Art Unit: 1628
`
`Page 3
`
`(a) A patent may not be obtained though the invention is not identically disclosed or described
`as set forth in section 1 02 of this title, if the differences between the subject matter sought to
`be patented and the prior art are such that the subject matter as a whole would have been
`obvious at the time the invention was made to a person having ordinary skill in the art to which
`said subject matter pertains. Patentability shall not be negatived 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 pre-AlA 35 U.S.C. 1 03(a) 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.
`
`This application currently names joint inventors. In considering patentability of the
`
`claims under pre-AlA 35 U.S.C. 1 03(a), the examiner presumes that the subject matter
`
`of the various claims was commonly owned at the time any inventions covered therein
`
`were made absent any evidence to the contrary. Applicant is advised of the obligation
`
`under 37 CFR 1 .56 to point out the inventor and invention dates of each claim that was
`
`not commonly owned at the time a later invention was made in order for the examiner to
`
`consider the applicability of pre-AlA 35 U.S.C. 1 03(c) and potential pre-AlA 35 U.S.C.
`
`1 02(e), (f) or (g) prior art under pre-AlA 35 U.S.C. 1 03(a).
`
`Claims 10-18 are rejected under pre-AlA 35 U.S.C. 1 03(a) as being unpatentable
`
`over Berger et al. (US 5,202,333) in view of Barton (Citrate Buffer Calculation, 2000,
`
`Exh. 1040
`
`
`
`Application/Control Number: 13/901 ,830
`Art Unit: 1628
`
`Page 4
`
`2pgs and Castillo et al., US 6,284,749 further in view of Gambhir, US 5,854,270 and as
`
`evidenced by Matsumoto (All references have already been made of record).
`
`Berger et al. teaches a pharmaceutical solution for reducing emesis, comprising
`
`palonosetron in a pharmaceutical acceptable carrier. See col. 2, lines 20 to 25 and col.
`
`12, lines 41-52 and col. 3, lines 17-21 ). Palonosetron is (as shown) is represented by
`
`formula I, at col. 8, lines 35 to 40). The reference also discloses that the
`
`pharmaceutically acceptable salt is hydrochloride and can be in an injectable form (see
`
`col. 12, lines 25-29) .. See col. 5, lines 2-3. With regard to the concentration
`
`palonosetron, the reference discloses the concentration is from 0.000001% w to 10%
`
`weight. Interpreting that assuming 100% is 100 ml, therefore in 1 ml (1 000 mg) the
`
`equivalent of 0.03mg/ml is 0.00003 wt %which is within the disclosed range, see col.
`
`12, lines 65-67 (claims 1 0) in a preferred single unit dosage form (see col. 13, lines 1-5).
`
`Berger also teaches the addition of citric acid buffer (see col. 28, lines 62-67, as
`
`required by instant claim 16)
`
`However Berger fails to teach that the composition comprises mannitol (from 1 0
`
`-80 mg/ml) and EDTA (from 0.005-1.0 mg/ml) wherein the formulation is stable for 24
`
`months in a 5 ml sterile aqueous solution (as required by instant claims 12-15)
`
`Barton is introduced for the teaching of the use of buffers in solution
`
`therefore in order to buffer solution that that is close to the desired ranges. In the instant
`
`claim the pH is 4-6, the pK's used for citric acid are 3.15, 4.50 and 5.75, therefor it is
`
`best to buffer at a pH close to one of the pK's, therefore use citrate buffers only in the
`
`pH range 3-6, since the required pH is from 4.0-6.0 (claim 4). Additionally Barton
`
`Exh. 1040
`
`
`
`Application/Control Number: 13/901 ,830
`Art Unit: 1628
`
`Page 5
`
`teaches buffers are used to adjust the pH of liquid drugs to keep the solubility and
`
`chemical stability and to decrease the irritation of the drugs. Thus the concentration of
`
`the citric acid will depend on the buffering condition of the solution.
`
`Castillo et al. teach the most preferred chelating agent in pharmaceuticals
`
`composition is EDT A. The chelating agents can be added to pharmaceutical
`
`compositions in the form of a pharmaceutically acceptable salt. For example, EDTA
`
`may be added in the form of edetate disodium. In general, the amount of chelating
`
`agent present in the compositions is from about 0.001 to about 1 %, preferably about
`
`0.01 to about 0.2%, and most preferably about 0.01 to about 0.1 %, which is within the
`
`claimed concentration in instant claim 7. See col. 3, lines 1-16. Therefore it would have
`
`been obvious to one of ordinary skill in the art to substitute citric acid for EDTA as the
`
`chelating agent since substituting one for another will have the same effect, stabilizing
`
`the formulation. Castillo teaches unit dose of their composition in the range of 1- 15 ml
`
`(see col. 4, lines 65-67). Thus it would have been obvious to one of ordinary skill in the
`
`art to formulate the unit dose formulation in 5 ml as required by the instant claim.
`
`Additionally Berger specifically teach that their formulations can be in a preferred unit
`
`dosage form, therefore, since the concentration can be at the dosage range/ml thus can
`
`be formulated in any amount as a single dosage use with a reasonable expectation of
`
`success.
`
`Gambhir et al. teach that the liquid composition for oral administration comprises
`
`ondansetron and a sweetener wherein the sweetener comprises one or more polyhydric
`
`Exh. 1040
`
`
`
`Application/Control Number: 13/901 ,830
`Art Unit: 1628
`
`Page 6
`
`alcohol (see column 2 lines 11-16). Column 2 line 40 of Gambhir lists mannitol as one
`
`species of polyhydric alcohol for use in the invention.
`
`Gambhir further teaches (column 2 lines 44-48) that the total polyhydric alcohol
`
`content of the liquid composition conveniently lies in the range of 20 to 85% weight by
`
`volume. Gambhir discloses a liquid composition for oral administration comprising
`
`another 5HT3 receptor antagonist, ondansetron, wherein the pH of the composition lies
`
`in the range of 2.0 to 5.0 (see column 2 lines 11-16 and abstract as required by instant
`
`claim 6). The composition disclosed in Gambhir is also generally used to treat emesis
`
`regardless of the cause (see column 4 lines 23-26). Therefore it would be obvious to an
`
`ordinary skilled artisan to formulate the composition of Berger et al. at a pH of about 2.0
`
`to 5.0 which overlaps with the ranges of pH claimed in the instant application since
`
`palonosetron and ondansetron (claim 1 of Gambhir) have similar structures that both
`
`block 5HT3 receptors and have the same utility of treating emesis.
`
`It would have been obvious to one of ordinary skill in the art to have used the
`
`teaching of Berger et al. administer the 5-HT3 receptor antagonist -palonosetron for the
`
`treatment of emesis because the reference teaches palonosetron is used in treating
`
`emesis.
`
`Also, it would have been obvious to one of ordinary skill in the art to substitute
`
`glucose (Berger's reference) to mannitol because absent factual evidence mannose is
`
`identical to glucose except for the orientation of the H and OH on carbon 2. Therefore
`
`one of ordinary skill in the art would be motivated to substitute glucose for man nose or
`
`vis--versa and would expect the same result. Although, the reference do not teach
`
`Exh. 1040
`
`
`
`Application/Control Number: 13/901 ,830
`Art Unit: 1628
`
`Page 7
`
`EDTA, it is known in the art that EDTA is a chelating agent, one of ordinary skill in the
`
`art would have been motivated to use the teaching of Castillo et al. add a concentration
`
`of EDTA that will be capable of stabilizing the solution, therefore, one of ordinary skill in
`
`the art would be motivated to add a carrier salt of EDTA to a pharmaceutical solution for
`
`stability and its antioxidant action as taught (see above discussion). Optimization of the
`
`concentration is within the purview of one of ordinary skill in the art, since it is known
`
`that these salts aid in stability one of ordinary skill in the art would be motivated to
`
`optimize and use the range or concentration that will s prolong stability.
`
`One of ordinary skill in the art would be motivated to use citric acid in buffering a
`
`solution to obtain the a pH of 4.0-6.0 because the art teaches its best to buffer at a pH
`
`close to one of the pK's, so use citrate buffers only in the pH range 3-6. See underlining.
`
`Based on the teaching it is well within the level of one of ordinary skill in the art to
`
`incorporate citrate buffer to a pharmaceutical composition having the pH in the range of
`
`4-6 because it is known in the art.
`
`With regards to a single unit dosage form, although Berger did not per say teach
`
`a single dosage form, nonetheless Berger specifically teach that the amount of
`
`Palonosetron may vary widely depending upon the type of formulation, size of the unit
`
`dosage etc., therefore based on Berger's teaching alone, it would have been obvious to
`
`one of ordinary skill in the art to have formulated a single, unit dosage form having a
`
`volume of 5 ml comprising 0.05 mg/ml with a reasonable expectation of success
`
`because Berger makes it obvious to do so (see col. 12, lines 60-68).

`
`As to the limitations to reduce the likelihood of cancer chemotherapy-induced
`
`nausea and vomiting and is stable for 24 months and 18 months is given no patentable
`
`weight because the claimed structure is already known. See In re Schreiber, 128 F.3d
`
`1473, 1477 (Fed. Cir.1997). While features of an apparatus may be recited either
`
`structurally or functionally, claims directed to an apparatus must be distinguished from
`
`the prior art in terms of structure rather than function. /d. at 1477-78; see also Hewlett-
`
`Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1468 (Fed. Cir. 1990). "[A]pparatus
`
`claims cover what a device is, not what a device does."
`
`Therefore the claim invention is prima facie obvious at the time of filing.
`
`Double Patenting
`
`The nonstatutory double patenting rejection is based on a judicially created
`
`doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the
`
`unjustified or improper timewise extension of the "right to exclude" granted by a patent
`
`and to prevent possible harassment by multiple assignees. A nonstatutory double
`
`patenting rejection is appropriate where the claims at issue are not identical, but at least
`
`one examined application claim is not patentably distinct from the reference claim(s)
`
`because the examined application claim is either anticipated by, or would have been
`
`obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d
`
`1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir.
`
`1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re VanOrnum,

`
`(CCPA 1970); and In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
`
`A timely filed terminal disclaimer in compliance with 37 CFR 1.321 (c) or 1.321 (d)
`
`may be used to overcome an actual or provisional rejection based on a nonstatutory
`
`double patenting ground provided the reference application or patent either is shown to
`
`be commonly owned with this application, or claims an invention made as a result of
`
`activities undertaken within the scope of a joint research agreement. A terminal
`
`disclaimer must be signed in compliance with 37 CFR 1.321 (b).
`
`The USPTO internet Web site contains terminal disclaimer forms which may be
`
`used. Please visit http://www.uspto.gov/forms/. The filing date of the application will
`
`determine what form should be used. A web-based eTerminal Disclaimer may be filled

`
`Claims 1-9 are provisionally rejected under the judicially created doctrine of
`
`obviousness-type double patenting as being unpatentable over claims 56-58 of US
`
`patent application 14/052,925.
`
`Although the conflicting claims are not identical, they are not patentably distinct
`
`from each other. The reasons are as follows:
`
`Bothe application recites the same pharmaceutical composition comprising the
`
`same agents for reducing emesis and is stable for 18 to 245 months.
