Appeal 2007-3373
Application 10/477,363
1 z is 1 to 5, and
2 L is independently of each other a direct bond or a chemical
3 linking group,
4 with the proviso that the reaction product of the self-
5 condensation product of 3,5-dihydroxybenzoic acid and
6 4-hydroxyphenylmethyl carbinol benzotriazole is excluded.

8 According to Ciba, WO 97/012282 describes self-condensation
9 product of 3,5-dihydroxybenzoic acid and 4-hydroxyphenylmethyl carbinol
10 benzotriazole (Publication, ¶ 0028) and therefore a negative limitation is
11 apparently necessary to define subject matter which is novel.

13 Other claims argued separately are claims 4-5, 7 and 9.
14 Claims 4-5, 7 and 9 read:
15 4. A stabilizer according to claim 2 in which x is greater than
16 one and comprising two different additive moieties.
17
18 5. A stabilizer according to claim 4 in which the two different
19 additive moieties are … ultraviolet light absorber and hindered
20 amine light stabilizer moieties.
21
22 7. A stabilizer according to claim 2 in which the linking group
23 L is ―OCO― or ―COO― or is a hydrocarbylene comprising
24 the groups ―OCO― or ―COO―.
