14) The Examiner found that Alexander’s specification admits that
it was known in the art to inject waste solids having solid metal
hydroxides into subterranean wells. (Final Office Action, p. 2).
15) The Examiner found that Tate teaches that injecting waste
solutions into a subterranean well avoids above ground pollution
problems. (Id.).
16) The Examiner found that Tate teaches the desirability of
contacting waste solids with an acid prior to injection into the well in
order to dissolve existing precipitates and inhibit the formation of
further precipitates. (Id.).
17) The Examiner found that Lipford teaches that it is advantageous
to remove industrial wastes from surface ponds in order to prepare the
land for subsequent use or mitigate existing hazards. (Id. at 3).
18) The Examiner found that Oddo teaches that it is desirable to
filter liquids prior to injection into a well to minimize plugging of the
well and Alexander did not dispute this finding. (Id. at 2 and Appeal
Br. at 5).
