Dallas Hinton to Alexander Koryagin:

DH> Excellent question - turns out that the process was sort
DH> of patented!

DH> ..patent leather is a fine grain leather that is treated
DH> to  give  it  a glossy appearance. An early reference to
DH> patent leather is in the  1793  British  periodical  The
DH> Bee,  or  Literary Weekly Intelligencer, which notes, in
DH> an article entitled "Hand's  patent  leather",  that  "a
DH> gentleman  of  the name of Hand" in Birmingham, England,
DH> obtained a patent for preparing flexible leather  having
DH> a  glaze  and polish that renders it impervious to water
DH> and need only be wiped with a sponge to  restore  it  to
DH> its original luster.

Whereas  patent  medicine  is  a  patent fraud.  What is the
difference in the pronunciation of `patent' in the first and
second occurences in the previous sentence?
