disposed around an outer periphery of said core, said cladding
having a refractive index lower than that of said core;
rewinding, after said winding, around a second winding
member said coated optical fiber wound around said first winding
member, said second winding member being different from said
first winding member; and
holding, after said winding and before said rewinding, said
coated optical fiber in an atmosphere with a mean temperature T
(unit: °C, >0 °C) for a time greater than or equal to
30,000/T2(hr).

Appellants' claimed invention is directed to a method of
making an optical fiber product comprising a glass fiber and a
primary coating of a UV-cured resin layer. The method entails
winding the coated optical fiber on a first winding member and
rewinding the fiber on a second winding member. After winding
the fiber on the first winding member, but before rewinding the
fiber onto the second winding member, the fiber is held in an
atmosphere having a mean temperature T greater than or equal to
30,000/T2(hr). According to appellants, they have "discovered
and investigated a relationship between the temperature where the
