Appeal No. 1997-3036
Application No. 08/268,094
Kajiwara teaches that partially post-glycidylated epoxy resins can be formed by epoxidizing
phenolic hydroxyl groups and pendant alcoholic hydroxyl groups. (Kajiwara, col. 1, line 51 to
col. 2, line 21). The partially post-glycidylated epoxy resins are described as having excellent
heat resistance and toughness and the cured epoxy resin product is mentioned as extremely useful
in a wide variety of products, such as photoresists. (Kajiwara, abstract). Nevertheless, Kajiwara
fails to describe or suggest the presence of acrylate groups, let alone pendant acrylate groups, on
the partially post-glycidylated epoxy resins. Failing to mention the presence of acrylate groups,
Kajiwara simply does not disclose or suggest appellants' claimed epoxy acrylates.
The References Taken as a Whole
The Examiner submits that it would have been obvious to use the composition of Fekete
or Takiyama and replace their conventional epoxides with the post-glycidylated epoxides of
Green or Kajiwar as the secondary references disclose that their post-glycidylated epoxides
possess improved properties. The examiner also contends that an acrylated epoxide is merely an
epoxy resin with altered functional groups, wherein the matrix of the system is not changed.
As discussed above, the primary references Fekete and Takiyama relate to epoxides
formed from glycidyl ethers where the glycidyl groups are present only at the ends of their
respective compounds. Neither Fekete nor Takiyama contemplate the employment of a glycidyl
ether compound having pendant glycidyl ether moieties. Similarly, the secondary references,
Green and Kajiwara, fail to mention or suggest that post-glycidylated epoxides may be reacted
