`
`REMARKS
`
`Claims 1-24 were originally presented in the application.
`
`Claims 1, 7, 13, and 19 have been amended as shown above. Claims 25-28 have been
`
`added. Support for these amendments and claims can be found throughout the specification,
`
`at for example, paragraphs 0066 and 0067, and in Tables 1 and 5.
`
`No new matter has been added.
`
`Interview Summary
`
`The Examiner is thanked for the courtesies extended during the telephonic interviews
`
`conducted on December 16 and 19, 2013. During the interviews, agreement was reached that
`
`the claim amendments shown above would overcome the sole rejection of the claims over
`
`Oksche et al., US. Patent No.2010/0087470 or WO 2008/025791.
`
`35 U.S.C.
`
`103 Re'ection
`
`Claims 1-24 have been rejected under 35 U.S.C. § 103 as allegedly obvious over
`
`Oksche.
`
`Oksche discloses buprenorphine dosage forms and that naloxone may be present
`
`therein. Oksche also generally discloses that the dosage form may be films, but fails to
`
`provide any disclosure of how to make such films including both buprenorphine and
`
`naloxone. Moreover, Oksche is completely devoid of any teaching of Cmax values for
`
`naloxone. Thus, Oksche does not teach or suggest how to achieve the claimed Cmax values for
`
`buprenorphine and naloxone alone or in combination in a film composition. In addition,
`
`Oksche does not provide any direction as to how to achieve a non-divertible film that

`Serial No.: 13/964,975
`
`Filing Date: August 12, 2013
`Docket No.: 2333-2 CON II
`
`Page 10
`
`produces optimized buprenorphine release while simultaneously producing a Cmax for
`
`naloxone that is within the claimed invention. Accordingly, Oksche is insufficient to support
`
`a prima facie rejection of the present claims (prior to amendment) for obviousness.
`
`However, although believed unnecessary, and only in an effort to further prosecution,
`
`independent claims 1, 7, 13, and 19 have been amended as shown above to recite a ratio of
`
`buprenorphine to total polymer. As agreed in the examiner interviews, these amendments
`
`overcome the rejection of the claims as obvious over Oksche. Dependent claims 25-28, which
`
`depend directly from independent claims 1, 7, 13, and 19, respectively, have been added to
`
`recite a ratio of naloxone to total polymer.
`
`Conclusion
`
`In view of the foregoing, it is respectfully submitted that the rejection has been
`
`overcome and that this application is in condition for allowance. Favorable reconsideration
`
`and prompt allowance of the application are earnestly solicited.
`
`No fees are believed to be due with this submission. If any fee is required, the
`
`USPTO is hereby requested and authorized to charge the fee to the Deposit Account No. 08-
`
`2461. Such authorization includes authorization to charge fees for extensions of time, if any,
`
`under 37 CPR § 1.17 and also should be treated as a constructive petition for an extension of
`
`time in this reply or any future reply pursuant to 37 C.F.R. § 1.136.
