ClaimsNos.: because they relate to subject matter not required to be searched by this Authority, namely: 2. Claims Nos. : 1-42 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 : see FURTHER INFORMATION sheet PCT/ISA/210 3. Claims Nos.: because they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4 (a). Box 11 Observations where unity of invention is lacking (Continuation of item 2 of first sheet) This Intemational Searching Authority found multiple inventions in this international application, as follows : 1. As all required additional search fees were timely paid by the applicant, this International Search Report covers all searchable ciaims. 2. As all searchable claims could be searched without effort justifying an additional fee, this Authority did not invite payment of any additional fee. 3. 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.: 4. nj 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 7 The additional search fees were accompanied by the applicant's protest. No protest accompanied the payment of additional search fees. LJ International Application No. PCT/US 00/11813 FURTHER INFORMATION CONTINUED FROM PCTIISA/210 Continuation of Box I. 2 Claims Nos.: 1-42 Present claims 1-42 relate to an electrochromic medium comprising an anodic electroactive material and a cathodic electroactive material defined by reference to the parameter"the electroactive material having the smaller potential difference between the chemically reversible waves has a concentration in the electrochromic medium greater than that required to achieve a balanced concentration". The method of calculating the"balanced concentration"is not indicated in the description although it is indicated that the"balanced concentration"is the concentration required to achieve a balanced current. The use of this parameter in the present context is considered to lead to a lack of clarity within the meaning of Article 6 PCT. It is impossible to compare the parameter the applicant has chosen to employ with what is set out in the prior art. The lack of clarity is such as to render a meaningful complete search impossible. Consequently the search has been restricted to the examples provided in the description. The applicant's attention is drawn to the fact that claims, or parts of claims, relating to inventions in respect of which no international search report has been established need not be the subject of an international preliminary examination (Rule 66.1 (e) PCT). The applicant is advised that the EPO policy when acting as an International Preliminary Examining Authority is normally not to carry out a preliminary examination on matter which has not been searched. This is the case irrespective of whether or not the claims are amended following receipt of the search report or during any Chapter II procedure.
