Part III Amendment of Description, Claims and Drawings
Example 19 concerning the analyzing process of a new matter
Category: Disclaimer
Original Description, etc
Title of the Invention
Photosensitive plate for planography
Scope of Claims
[Claim 1]
A photosensitive plate for planography
which has a photosensitive layer, on a
hydrophilically treated aluminum plate, composed
of partially saponificated polyvinyl acetate having
saponification degrees of 60-80 mol % and a
photopolymerized monomer having at least one
ethylenic unsaturated bond, wherein the
photosensitive layer contains 1-100% by mass of
a nitrogen-containing heterocyclic carboxylic acid
for the partially saponificated polyvinyl acetate.
Excerpts from the Detailed Explanation of the
Invention
The present invention provides nitrogencontaining
heterocyclic carboxylic acid which
includes certain substances, such as picolinic acid
and isonicotinic acid. (A prior art describing the
“nicotinic acid” as “nitrogen-containing
heterocyclic carboxylic acid” was found.)

Scope of Claims
[Claim 1]
A photosensitive plate for planography
which has a photosensitive layer, on a
hydrophilically treated aluminum plate, composed
of partially saponificated polyvinyl acetate having
saponification degrees of 60-80 mol % and a
photopolymerized monomer having at least one
ethylenic unsaturated bond, wherein the
photosensitive layer contains 1-100% by mass of
a nitrogen-containing heterocyclic carboxylic acid
(excluding nicotinic acid) for the partially
saponificated polyvinyl acetate.
Excerpts from the Detailed Explanation of the
Invention
The present invention provides nitrogencontaining
heterocyclic carboxylic acid which
contains certain substances, such as
photopolymerized monomer and isonicotinic acid.
[Conclusion]
The amendment is within the scope of the matters stated in the originally attached description, etc.
[Explanatory Note]
The amended claim mentions “nitrogen-containing heterocyclic carboxylic acid (excluding
nicotinic acid),” a partial change of the original claim, which explicitly excludes only the art disclosed as a
prior art. Consequently, this example is included in the cases where the claim should be amended within the
scope of the matters stated in the originally attached description, etc.
A “disclaimer” approach should be adopted in the potential invention only when the filed invention
is an art totally different from prior art in view of the technical idea and basically has an inventive step, but
has an overlapped section with the prior art by chance.
