Appeal 2007-2677
Application 10/622,229
The Examiner found that Darsillo discloses a recording medium that
has a glossy coating and comprises first and second groups of particles.
Answer 3.1 We find that the median diameter of the first group of particles
(less than about 100 nm) overlaps the claimed median size of the
Appellants’ small particles (between 80 and 140 nm), and the median
diameter of the second group of particles (less than about 300 nm) overlaps
the claimed median size of the Appellants’ large particles (between 200 and
300 nm). The Examiner also found that the ratio of first to second groups of
particles disclosed in Darsillo overlaps the claimed ratio of large to small
particles. Answer 3-4.
The Examiner found that Darsillo does not appear to disclose the
actual porosity of the medium. In any event, the Examiner found that the
medium disclosed in Darsillo would be inherently porous. The Examiner
concluded that based on the awareness in the prior art of the importance of
porosity, it would have been obvious to one of ordinary skill in the art to
optimize the porosity of the layer in order to obtain the desired ink
absorption capacity. Answer 4.
The Examiner found that Darsillo is concerned with gloss but does not
measure gloss in the terms set forth in the claims. The Examiner concluded
that it would have been obvious to one of ordinary skill in the art to control
the gloss of the recording medium based on the desired visual results sought
to be achieved. Answer 4.
The Examiner found that the particles in Darsillo may be made
cationic by a surface treatment with an inorganic salt (e.g., aluminum
chlorohydrate), organic silanes, or a polymer (e.g., a polyamine). The
