requiring use of a saturated mono-ol as one of the three
alcoholic reactants involved in preparation of appellant’s
composition. Also, we are mindful that Takayama suggests using a
saturated mono-ol as one of two alcoholic reactants to produce
certain urethane compounds, and demonstrates (Table 3) that the
inclusion of a saturated mono-ol is instrumental in avoiding
generation of cracks when producing in-mold cured products.
That being said, we agree with the appellant that the
differences between the Meixner and Takayama compositions would
