amylase, protease, mutanase, lysozyme, lytic enzyme, etc.” Id. at Column 3,
lines 9-13.
Thus, we can find nothing in either Römisch EP or Sato that would
suggest to one of ordinary skill in the art to add tranexamic acid to the protease
of Römisch EP as Sato in fact teaches that compositions containing tranexamic
acid are unstable, and teach methods of stabilizing the composition. Nor does
the examiner point to, nor do we find, anything in Roy or Kessler that would
remedy that deficiency. Thus, the combination does not suggest adding the
tranexamic acid as taught by Sato to the protease taught by Römisch EP to
stabilize the protease as set forth in the rejection, and the rejection must be
reversed.
The examiner argues, citing example 4, “that Sato found the tranexamic
acid to stabilize compositions.” Examiner’s Answer, page 5. Example 4 states,
however, “that the aging stability of tranexamic acid-containing compositions is
improved when CMC and carrageenan are blended at a ratio of 6:4 to 10:0.” Id.
at Column 7, lines 56-59. Thus again, the tranexamic acid is being stabilized in
the example, and not acting as a stabilizer.
