Appeal 2007-4227
Application 10/409,417
33. The "liquid pyrolysis" described by Chopin appears to be reasonably
described as a "spray pyrolysis" process.
34. In Example 7, Chopin reports using a dispersion of titanium dioxide
particles containing 0.1% niobium-doped titanium dioxide particles (made in
Example 2 with an Nb/TiO2 molar ratio in the starting materials of 0.1%).
(Chopin at 19:1–5 and at 16:30–34.)
The Rejections and Counterarguments
Anticipation
35. The Examiner finds that Chopin teaches adding a dopant including
metals recited in claim 1, to titania-containing material. (Answer3 at 3;
FF21.)
36. The Examiner finds that adding the dopant inherently shifts the
temperature of the amorphous-to-crystalline transition. (Answer at 3.)
37. The Examiner finds further that Chopin teaches application of the
titania-containing layers by CVD or spray pyrolysis. (Answer at 3.)
38. The Examiner also finds that Chopin teaches that its doped titania
coatings are photocatalytic and [photo]hydrophilic, and concludes that the
coatings are therefore photo-active and photohydrophilic as required by
claims 13 and 14. (Answer at 3.)
39. Kutilek acknowledges the Examiner's findings of fact. (Br. at 3, first
paragraph.)
