Risk
An
inventor
pays
substantial
fees
to
renew
patents
every
year.
Though
he
brushed
with
bankruptcy
during
the
development
years,
for
James,
it
was
money
well
spent.
In
1999,
after
a
lengthy
court
battle,
Hoover
Europe
was
found
to
have
infringed
James'
patent.
Other
manufacturers,
unable
or
unwilling
to
develop
their
own
technology,
still
try
to
copy
Dyson
cleaners
to
no
avail.
