`INTERNATIONAL SEARCH REPORT
`
`International application No.
`PCT/U52017/050817
`
`Box No. II
`
`Observations where certain claims were found unsearchable (Continuation of item 2 of first sheet)
`
`This international search report has not been established in respect of certain claims under Article 17(2)(a) forthe following reasons:
`
`Claims Nos.:
`because they relate to subject matter not required to be searched by this Authority, namely:
`
`Claims Nos.:
`because they relate to parts of the international application that do not comply with the prescribed requirements to such
`an extent that no meaningful international search can be carried out, specifically:
`
`Claims Nos.:
`because they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4(a).
`
`Ill Observations where unity of invention is lacking (Continuation of item 3 of first sheet)
`
`This International Searching Authority found multiple inventions in this international application, as follows:
`
`see additional sheet
`
`
`
`As all required additional search fees were timely paid by the applicant, this international search report covers all searchable
`claims.
`
`As all searchable claims could be searched without effort justifying an additional fees, this Authority did not invite payment of
`additional fees.
`
`As only some of the required additional search fees were timely paid by the applicant, this international search report covers
`only those claims for which fees were paid, specifically claims Nos.:
`
`No required additional search fees were timely paid by the applicant. Consequently, this international search report is
`restricted to the invention first mentioned in the claims; it is covered by claims Nos.:
`
`Remark on Protest
`
`The additional search fees were accompanied by the applicant‘s protest and, where applicable, the
`payment of a protest fee.
`
`The additional search fees were accompanied by the applicant‘s protest but the applicable protest
`fee was not paid within the time limit specified in the invitation.
`
`IE No protest accompanied the payment of additional search fees.
