`
`the internatisnai ahpiimtion in the ianguage in which it was tiied
`
`, which is the tanguage
`a a transiatiori at the iriternatienai appiicatiori into
`of a trarisiation furnished tor the purposes of international search (Ruies 123(3) ahci 23.1(b))
`
`into account the reotitioatisn of an obvious mistake
`This internationai search report has been estabiishedt
`authorized by or hotitied to this Authority under Ruie 91 (Ruie 43.6t‘fiis(a))v
`
`With regard to any nucieotide and/er amine acid sequence disoiosed in the internatioriai aoptioation, see Box No. i,
`
`
`
`Certain oiaims were tound unsearohahie {See Box No. it)
`
`Unity at invention is tacking (see Box No iii}
`
`With regard to the titie,
`
`the text is approved as submitted by the appiioant
`
`D the text has been estabiished by this Authority to read as foiiows:
`
`With regard to the abstract,

`
`With regard to the drawings,
`
`a.
`
`the figure of the drawings to he pubiished with the abstract is Figure No
`as suggested by the appiioant
`
`as seieoteoi by this Authority, because the appiioant failed to suggest a figure
`as seiected by this Authority, because this figure better characterizes the invention

`The additiohai features of oiaims 10 and it do not provide any partieuiar advantage
`
`or soive a partieuiar prohiem in view of the disoiosure of anyi of Di to [34. Thus, they
`
`oannot contribute to an inventive step.
`
`The additionai feature of oiaim 17,. i.e. appiying one or more iayers by printing, is a
`modification of the method known form each of Di to D4 whioh comes within the
`
`routine of a skiiied personiThe Apparentiy there is no advantage provided by the
`additionai feature of oiairn it).
`
`Maintaining an appropriate temperature during the firing step atone does not seive the
`
`prohiem posed, see item Viii heiow. Ciairn 18 is therefore not based on inventive
`
`activity.
`
`Further, the subject—matter of oiairn 2“:
`
`is not inventive because it is obvious to a

`
`Certain observations on the internationai appiioation
`
`it wouid appear from the exarnpies of the present appiioation that insufficient giass
`
`ieading and firing at too high temperature resuit in iow durahiiity. it can therefore he
`ooneiuded that these features in combination are essentiai to the definition of the
`
`invenhon.
`
`Since they are not inoiuded in the independent oiairns, these do not meet the
`
`requirement ioiiowing from Artieie 6 PCT taken in combination with Ruie 6.3(hi PCT
`
`that any independent claim must contain aii the teohnieai features essentiai to the
`definition of the invention.
