Appeal No. 1998-2834
Application 08/659,858
invention relates to a disposable absorbent article having an
adhesive disposed adjacent to a wearer’s skin. More
particularly, the invention relates to a catamenial device
having a supportive adhesive residing on the bodyside surface
of the device.” Appellants maintain that
[i]t is important to the invention that the adhesive
(22) have a specific tan * rheological parameter.
The adhesive tan * resides inside the quadrangle
ABCD. The quadrangle ABCD is defined by graphically
plotting frequency (in radians per second) verse
[sic, versus] tan * (referenced to about 20E
Centigrade). The quadrangle ABCD has as points A
and D a tan * of about 0.06 and 0.4 respectively at
a frequency of about 0.1 radians per second and
points B and C at a tan * of about 0.1 and about 1.7
respectively at a frequency of about 1000 radians
per second. [Brief, page 3.]
Adhesives having a tan * outside the quadrangle ABCD are
said to have insufficient adhesion and “quick stick” for
appellants’ purposes (specification, page 8).
A copy of claim 18, the sole independent claim on appeal,
appears in the appendix to appellants’ brief.
The prior art references of record relied upon by the
examiner in support of rejections under 35 U.S.C. § 103 are:
