particular manner and technique. The Asanuma
process as set out in Example 3 is not specific and
hence is unrepeatable and unreproducible--too many
essential details are missing. The specific process
actually adopted by Asanuma for the "repeats" of
Example 3 is utterly unsupported by the text of that
Example. Thus, the Asanuma application altogether
fails to disclose or suggest the Galimberti process
as set out in Galimberti patent claim 2.
The following table compares the processes of the
parties.
