Appeal 2006-2571
Application 09/759,179
anisotropic etching of a surface of a mold into a patterned mold
surface, such that a first recess and a second recess are created in the mold
with apertures in the original surface, which first recess and a second recess
become narrower as its distance to the original surface increases and has
cross-sections parallel to the original surface which, when projected
perpendicularly on the original surface, lie within the aperture, and wherein
the first and second recesses have different apertures;
disposing an unmolded agent between the mold and a first body; and
making a replica of the patterned mold surface in the first body with a
patterned surface, wherein the replica contains structures of different sizes.
7. A method as claimed in claim 6, characterized in that a replica is
made of the patterned surface of the first body in a second body which has a
patterned surface.

by Hawkins as applied to claim 1 and further in view of Maracas (id. 5);
claims 6 and 11 through 13 as unpatentable over Whitesides in view of
Biebuyck (id. 5-6);
