1. The mere change in form of a soluble article of commerce, by
reducing it to small particles so that its solution is accelerated
and it is rendered more ready for immediate use, convenient for
handling, and, by its improved appearance, more merchantable, does
not make it a new article within the sense of the patent law.
2. To render an article new within that law, it must be more or
less efficacious, or possess new properties by a combination with
other ingredients.
3. Reissued letters patent No. 4072, granted July 12, 1870, to
Thomas P. Milligan and Thomas Higgins, assignees of Emerson
Goddard, for an improvement in the manufacture of glue, the alleged
improvement consisting "of glue comminuted to small particles of
practically uniform size, as distinguished from the glue in angular
flakes hitherto known," are void for want of novelty.

This is a suit in equity by the Milligan and Higgins Glue
Company against George Upton, for the alleged infringement of
reissued letters patent No. 4072 for an improvement in the
manufacture of glue, granted July 12, 1870, to Thomas P. Milligan
and Thomas Higgins, assignees of Emerson Goddard, upon the
surrender and cancellation of original letters patent No. 44,528,
issued to the latter Oct. 4, 1864. The complainant is the assignee
of Milligan and Higgins. The bill prays for an injunction and for
an account of the defendant's gains and profits arising from the
manufacture and sale of the patented article. Upon hearing, the
court below dismissed the bill, whereupon the complainant appealed
here. The facts relating to the alleged invention are stated in the
opinion of the Court.
MR. JUSTICE FIELD delivered the opinion of the Court.
In the court below, the defendant questioned the validity of the
surrender of the original patent and of the reissue, but, from the
view we take of the alleged invention or discovery, it is
unnecessary to consider this point. We shall treat the reissue as
for the same invention or discovery, differing in no substantial
particular from that originally patented. In the specification
accompanying the reissue, the patentee states that he has invented
a new and useful article, which he denominates "instantaneous or
comminuted glue," and then proceeds to describe the glue of
commerce previously found in the market, and to point out the
inconveniences attending its use, and the manner in which they are
obviated by his invention. He states that the ordinary glue of
commerce was then sold in the form of hard angular flakes, and that
it required a good deal of time to prepare it for use -- first by
soaking it in cold water and afterwards by heating it in a hot
water bath until the flakes were dissolved. The time thus occupied,
he says,
Page 97 U. S. 5
is saved by his invention, as his article does not require to be
prepared for solution by soaking, is quickly permeated by water, so
that it can be dissolved in large quantities ready for mechanical
use in less than five minutes, and in smaller quantities for
domestic use in less than one minute. Another objection stated to
the glue of commerce as previously sold is, that great
inconvenience was experienced in retailing it, from the difficulty
of putting it up in small packages, by reason of the sharp, angular
corners and edges of the broken flakes, which cut the wrappers,
causing a waste of time and stock. The new article, he says, can be
put up by machinery or by hand into packages of uniform size and of
regular form and weight, similar to those in which ground spices
are put up for domestic use, and sold by retail traders. He also
states that the new article has a more pleasing appearance than the
ordinary glue of commerce, in that it has a white color, and is
consequently more merchantable, and brings a higher price.
The specification then proceeds to describe the best process
which the inventor has devised for making such instantaneous glue,
and the apparatus or machinery he has used. These consist of a
breaking machine, for crushing the flakes into small pieces, and of
a rasping or grating machine, for comminuting the broken pieces
into uniform grains. But for these mechanical means or processes
the patentee makes no claim, observing, that it is obvious that
other means or processes of crushing or reduction may be used to
manufacture his article out of dry flake glue or gelatin by a
crushing or breaking operation, and that his claim is only to the
comminuted glue as a new article of manufacture.
It thus appears that the invention claimed is not any new
combination of ingredients, creating a different product, or any
new mechanical means by which a desirable change in the form of a
common article of commerce is obtained; but it consists only of the
ordinary flake glue reduced to small particles by mechanical
division. The advantages from such division consist in its more
ready and rapid solution, its greater convenience for packing and
retailing, and its whiter appearance and enhanced salableness. The
whole claim is to an old article of commerce in a state of
mechanical division greater than previously
Page 97 U. S. 6
used, but unchanged in composition and properties; and the
benefits arising from the increased division are such as appertain
to every soluble substance when divided into minute particles.
This statement, which is substantially a repetition in a
condensed form of that by counsel, is supported by reference to
numerous instances where similar results have followed the
mechanical division of soluble objects into small particles; but we
do not deem it necessary to mention them, for the point involved
presents no difficulty. There is nothing new in the fact that the
solution of a soluble substance is accelerated by increasing its
fragmentary division; nor is there anything new in the fact that
articles with rough angles and edges can be more readily put up
into packages without injury to their wrappers when reduced by
mechanical division into small particles; nor is there anything new
in the fact that such articles generally improve in appearance by
granulation or powdering.
A distinction must be observed between a new article of commerce
and a new article which, as such, is patentable. Any change in form
from a previous condition may render the article new in commerce;
as powdered sugar is a different article in commerce from loaf
sugar, and ground coffee is a different article in commerce from
coffee in the berry. But to render the article new in the sense of
the patent law, it must be more or less efficacious, or possess new
properties by a combination with other ingredients; not from a mere
change of form produced by a mechanical division. It is only where
one of these results follows that the product of the compound can
be treated as the result of invention or discovery, and be regarded
as a new and useful article. The three advantages attributed to
comminuted glue over the flake glue were, previous to the alleged
invention of Goddard, recognized as following from a division of
soluble objects into small particles, in the treatment of a great
variety of articles in constant use in the kitchens of families,
and in pharmacy. Where certain properties are known to belong
generally to classes of articles, there can be no invention in
putting a new species of the class in a condition for the
development of its properties similar to
Page 97 U. S. 7
that in which other species of the same class have been placed
for similar development, nor can the changed form of the article
from its condition in bulk to small particles, by breaking or
bruising or slicing or rasping or filing or grinding or sifting, or
other similar mechanical means, make it a new article, in the sense
of the patent law.
This subject is elaborately considered by the presiding justice
of the Circuit Court, in his opinion, with reference to numerous
adjudications of the courts of England and the United States, and
in his conclusion on this point we concur.
Decree affirmed.
