Ito
[10] Ito teaches (trans. at 2) the use of thin-film electrolytes for use in systems
requiring low film resistance and outstanding mechanical strength, such as fuel cells.
[11] The examiner compares Ito to the limitations of claim 1 as follows:3
Claim 1 Ito (translation)
An integral air impermeable "...preparing a thin porous film from
composite membrane comprising: polyolefin of a weight average
molecular weight of 5 × 105 or more
and filling the holes therein with an ion
exchange resin." At 3.
a fluorinated polymeric support [difference]
having a microstructure of "Similarly, the porosity of the porous
micropores, said microstructure thin film is preferably 40% to 90%, and
defining a porosity in the range of more preferably 60% to 90%." At 4.
about 70% to 98% within said
polymeric support,
2 All citations to Ito are actually to the English translation of record.
3 The examiner's answer does not provide much in the way of specific citation to the relevant portions of the
references. Thus, the reference citations reflect our inference regarding the examiner's intent.
