PTAB affirms examiner in Ex parte Mabey
The PTAB affirmed the examiner in Ex parte Mabey.
The technical matter involved the addition of an intumescent agent in a latex based paint.
GrafGuard, a graphite intercalated with sulfuric acid/nitric acid arose in the discussion.
Appellants made an argument that the Armstrong prior art was in a different patent classification group, and thus not analogous. This did not fare well.
In re zgurley is cited as to teaching away.
