Appeal No. 95-1484
Application 08/070,650
microbially produced cellulose under conditions of
agitation, said cellulose being characterized by a high
frequency of thickened branched substantially continuous
cellulose strands that interconnect to form reticulated
grid-like structure extending in three dimensions, said
sheet showing a high degree of resistance to
densification
by wet compression.
3. The cellulosic sheet of claim 1 wherein the
microbial cellulose is produced by a cellulose producing
organism of the genus Acetobacter.
4. The cellulosic sheet of claim 3 in which the
Acetobacter organism is resistant to mutation in agitated
culture to non-cellulose producing strains.
5. The cellulosic sheet of claim 4 wherein the
microbial cellulose is produced by a cellulose producing
organism of the species Acetobacter xylinum.
6. The cellulosic sheet of claim 5 wherein said
microorganism is selected from the group consisting
of Acetobacter xylinum ATTC 53264, 53263, and 53254,
corresponding to strains 1306-3, 1306-11, and 1306-21.
Johnson’s specification is practically, if not completely,
identical to the specifications supporting the claims of this
appeal and the claims of Ben-Bassat, U.S. 5,144,021.
On consideration of the claimed subject matter allowed in
Ben-Bassat, U.S. 5,144,021, and Johnson, U.S. 4,863,565, it
appears that the present examiner’s rejection of Claims 57,
64-66 and 68 in this application is inconsistent with the
allowance of similar subject matter by other examiners.
