Washington, Oct. 1S.-All the in
ventors in the world seem to have
turned their attention simultaneously to
aeronautics, and to have directed their
output of projects in one tremendous
broadside at. the patent office.
Six months ago one examiner handled
the patent office division in which aer-
onautics are directed, and he had rather
an easy time of it, withal business was
then distinctly looking up. But about
the time Blerriot flew across the Eng
lish channel, the inventors bestirred
them selves. From Germany, France,
Britain the United States, Italy and
in fact all over the world, they have
been sending into the Washington pat
ent office the drawings and models and
specifications and claims for their null
titudinous inventions. Many hundreds
of them have come within the last few
months, and the authorities declare
that the food sweeps stronger every
day.
From the one man who had an easy
thing holding down the division of
aeronautics six months ago, the force
has been expanded to two and then
three and still is not equal to the task.
1t is the busiest corner in the patent Of
fee just now.
And in connection with this remark
able development of interest all over
the world, there are forming the lines
fov ~
of certain fundamental patents on the
heavier-than-air machines. The Wright
brothers are understood TO have back
ing, which, confident of their priority
in the field, is determined to employ
every legal resource to protect them to
the utmost. The possibility looms
large. in short, of a Wright monopoly
in the business of building and oper-
ating aeroplanes of the bi-plane type
and perhaps even some of the mono
planes
The tremendous possibilities of mo-
nopoly of this kind have attracted wide
attention among enterprising capital
lists who would like TO have slice OF
the profits to be reaped from such 6
control. 1t is possible to explain the
nature of the Wright contention by tell
ing the facts about the Wright litiga.

charge of infringement.
The Wright application for paten
was granted May %, 1906. 1t was de
signed to cover a machine with tw'
parallel planes, SO organized that tn
sides and ends could be warped" il
either direction, so as to change tn
angle at which they should strike tn
lair. This '-warping" feat ure was tn
essential of their mechanism. In thei
application for patent, their claim
