`
`Amendment to the Claims
`
`1.
`
`(Currently amended) A sublingual—fen’eanyl—forrnulation comprising discrete liquid

`
`REMARKS
`
`Claims 1, 4 and 5 are pending. Claims 1 and 4 are currently amended. Support for the
`
`amendment to claim 1 regarding specific fentanyl derivatives can be found in paragraph [0043]
`
`of the specification. Support for the amendment to claim 1 regarding droplet diameter can be
`
`found in paragraph [0020] of the specification. Support for the amendment to claim 4 can be
`
`found in paragraph [0099] of the specification. Claim 5 is new.
`
`35 U.S.C. § 112 rejections
`
`Claim 1 remains rejected under 35 U.S.C. § 112, first paragraph, for lack of enablement
`
`and written description. The Office Action maintains that the specification “does not reasonably
`
`provide enablement for sublingual formulations comprising ‘derivatives thereof’ ”. Applicants
`
`respectfully traverse this rejection. Amended claim 1
`
`is limited only to fentanyl and those
`
`derivatives disclosed in paragraph [0043] of the specification (i.e. sufentanil, carfentanil,
`
`lofentanil,
`
`alfentanil).
`
`Each of these analogues possesses
`
`the
`
`same N-Phenyl-N-(4-
`
`piperidinyl)propanamide backbone as fentanyl and differ only slightly in the substituents of that
`
`backbone. All of these analogues and their effective amounts are well known in the art. What is
`
`not well known in the art are sublingual formulations of fentanyl or these analogues that have
`
`discrete liquid droplets having a mean diameter of from about 30 to about 70 microns. This
`
`slight variation in the identity of the substituents that are attached to the backbone should have
`
`little to no effect on the ability to form these discrete liquid droplets. Thus, taking any of the
`
`sublingual fentanyl formulations from the specification, which the Office Action admits are
`
`enabling, and replacing an effective amount of fentanyl with an effective amount of one of these
`
`analogues would not impose undue experimentation on a person having ordinary skill in the art
`
`(“PHOSITA”). Thus, applicants respectfully request withdrawal of this rejection.
`
`Claiml is rejected under 35 U.S.C. § 112, second paragraph, for lack of definiteness.
`
`The Office Action asserts that the claim is confusing because it
`
`is drawn to a fentanyl
`
`formulation, however, allows for derivatives which are not fentanyl.
`
`Claim 1 has been
`
`amended to be drawn to a sublingual
`
`formulation.
`
`Thus, applicants respectfully request
`
`withdrawal of this rejection.

`
`Response to Office Action mailed March 21, 2014
`Serial No. 13/895,124
`
`35 U.S.C. §§102/103 Rejections
`
`McCarty
`
`Claims 1 and 4 remain rejected under 35 U.S.C. §§ 102(e) as anticipated by or, in the
`
`alternative under 103(a) as obvious over McCarty (US 2007/0071806). The Office Action
`
`asserts that McCarty teaches sublingual fentanyl formulations which comprise ETOH and PG.
`
`The Office Action admits that McCarty does not teach droplet sizes of from about 30 to about 70
`
`microns. The Office Action asserts that the burden is on the Applicants to show a novel or
`
`unobvious difference between the claimed product and the product of the prior art, citing In re
`
`Best, 562 F.2d 1252 (CCPA 1977).
`
`Applicants respectfully traverse this rejection. In In re Best, the court found that the later
`
`filed application was anticipated and obvious over an earlier patent despite the fact that the
`
`application’s claims had an additional element not taught by the earlier patent, namely a cooling
`
`rate. The court found that removing the heat source would necessarily lead to the cooling rate
`
`claimed and that the applicants failed to show that normal cooling rates were not sufficient for
`
`the process described in the application.
`
`In re Best, does not apply to the instant application because the situation is not analogous.
`
`The additional element claimed in the instant application’s claim 1, namely discrete droplets
`
`having a mean diameter of from about 30 to about 70 microns, does not necessarily result from
`
`the product taught in McCarty. McCarty teaches that a fentanyl formulation could contain
`
`ethanol and propylene glycol. However, McCarty does not teach that these formulations are
`
`limited to those that are capable of forming discrete droplets having a mean diameter of from
`
`about 30 to about 70 microns. Any fentanyl formulation containing ethanol and propylene
`
`glycol will not necessarily result in discrete droplets having a mean diameter of from about 30 to
`
`about 70 microns. Additionally, McCarty does not teach the concentration ranges described in
`
`claim 4 of the instant application.
`
`Furthermore,
`
`all of McCarty’s examples
`
`teach
`
`sublingual/buccal tablets, which as a solid do not contain droplets.
`
`The Office Action contends that even if McCarty does not meet the limitations of the
`
`instant invention under 10[2], it would still have been obvious at the time of the instant invention
`
`to have optimized the conditions to provide a formulation with a rapid/desired onset of action to
`
`reduce pain quickly as possible.
`

`
`

`
`Response to Office Action mailed March 21, 2014
`Serial No. 13/895,124
`
`McCarty does not
`
`teach or suggest
`
`that a formulation comprising fentanyl or its
`
`derivatives (sufentanil, carfentanil, lofentanil and alfatenil) of any particular droplet size would
`
`be useful for treating pain. Thus, a PHOSITA would not have found it obvious to optimize the
`
`conditions taught in McCarty, namely sublingual/buccal tablets, to provide the instantly claimed
`
`invention of a sublingual spray comprising fentanyl or its derivatives (sufentanil, carfentanil,
`
`lofentanil and alfatenil) with discrete liquid droplets having a mean diameter of from about 30 to
`
`about 70 microns. Additionally, McCarty does not make obvious the specific concentrations of
`
`ETOH and PG in claims 4 and 5.
`
`Ross 2003, Ross 2006 or McCarty in View of W7’llTf[€
`
`Claims 1 and 4 are rejected under 35 U.S.C. 103(a) as being unpatentable under either
`
`Ross (US 2003/0190290) (“Ross 2003”), Ross (US 2006/0062812) (“Ross 2006”) or McCarty
`
`each in view of Whittle. The Office Action asserts that Ross 2003, Ross 2006 and McCarty each
`
`teach sublingual fentanyl formulations as claimed. The Office Action further asserts that Whittle
`
`teaches pharmaceutical formulations for sublingual use which have a droplet size of 15 to 45
`
`microns and the claimed proportions of ETOH/PG.
`
`Applicants respectfully traverse this rejection. None of the references in view of Whittle
`
`teach a fentanyl or fentanyl derivative (sufentanil, carfentanil, lofentanil, alfentanil) sublingual
`
`formulation with a discrete liquid droplet having a mean diameter of from about 30 to about 70
`
`microns. Furthermore, Whittle teaches ETOH/PG ratios of 60/40 to 40/60. Instant claim 4 and 5
`
`have an ETOH/PG ratio 50/4 to 60/6. Thus, none of the references in view of Whittle would
`
`make it obvious to a PHOSITA to vary the formulations disclosed in these references to arrive at
`
`the instant claimed formulations. Accordingly, Applicants respectfully request
`
`that these
`
`rejections be withdrawn.

`
`SUMMARY
`
`None of McCarty, Ross 2003, Ross 2006 or Whittle alone or in combination teaches or
`
`makes obvious the formulations of claims 1, 4 or 5. Applicants respectfully submit that the
`
`pending claims 1, 4 and 5 are patentable. Accordingly, reconsideration of the rejections and
`
`allowance of the application are requested. Should the Examiner have any questions concerning
`
`the above, he is respectfully requested to contact the undersigned at the telephone number listed
