`1.3
`
`It is at present not clear if the compounds as claimed in present claims 1 to 4 and 14
`
`are identical ("Form A") or represent different compounds.
`
`If all claims refer to one single compound (as it can be read from page 1 of the
`
`description) then this compound has to be characterised by all features of claims 1 to
`
`4 (EPC Article 84)
`
`It is not clear if the processes of present claim 5 and claim 11 result in the same
`
`(EPC Article 84).
`compound ("Form A")
`Present claim 16 which is directed to the use of "Form A" refers back to "claims 1 to
`
`14".
`
`However, present claims 5 to 13 relate to a process for preparing "Form A".
`
`Amendments are requested to overcome this deficiency (EPC Article 84).
`
`There are no figures 1 to 8 on file.
`
`Since figure 1
`
`is missing, present claim 3 is so unclear that no examination can be
`
`done (EPC Article 84).

`
`3.
`
`From the data presented in tables 1 to 4 it appears that "Form A" as mentioned in
`these tables is different from "Form B" which is known from D1.
`
`The subject matter of present claims 1 to 2 , 4 to 16 can thus be regarded as being
`
`novel
`
`(EPC Article 54).
`
`4.
`
`In view of D1, the underlying problem can be defined byte provision of an alternative
`
`form of the known compound (—)—(1 R,2R)—3—(3—dimethylamino—1—ethyl—2—
`
`methylpropyl)—phenol hydrochloride.
`
`The proposed solution is the provision of a "Form A" of this compound.
`
`This solution is to be regarded as representing an obvious measure in the absence of
`
`any evidence that this new form shows any surprising or superior effect over the
`known form.
`
`Such data have to be clearly shown by comparing the features of the claimed
`
`compound with the prior art compound.
`
`Since such an effect is not shown in present application, the subject matter of present
`
`claims 1 to2, 4 to 16 is considered not to be based on an inventive step (EPC Article
`
`56).
