PREFACE.
The present book is more than a revision of my Process Digest, since
it is entirely rewritten, all the cases being reread from the point of view
of an attorney and expert witness, instead of that of a Patent Office
Examiner. For this reason there are specific notes on the kind of evi-
dence needed in chemical and allied cases, and also notes covering the
cases on damages, licenses, etc. No attempt has been made to criticize
any decision or the findings on which it is based. The book is intended
as a statement of the law, with a practically complete ''finding list" of
the cases on which the law of chemical patents is based, and it also in-
cludes the principal cases intimately related in reasoning to such cases.
While errors will undoubtedly be found it is believed that they are
only such as are easily recognized. I only regret that, unlike Eobinson,
I have not the leisure needed to spend two years in rereading and veri-
fying every cited case.
Cases are cited, from the reports most likely to be available, and
which in general indicate the authority of the decision ; viz : reports are
given preference in the following order U. S. (including Wallace etc.) ;
F. E.; 0. G.; Fish. (Pat. Cases); Fish. Pat. Reports; Robb (Pat.
Cases) ; Ban. and A. ; Blatschf ., etc. Readers who have only the Official
Gazette can rapidly locate the F. R. and U. S. cases included therein by
ascertaining the approximately parallel volumes from the table on page 4.
Since the number of cases cited approaches that in the larger works
on patent law, the notes have been condensed by citing in general, only
the appeal case, or the last case of a series, if that rules on all the points
previously raised, though where the prior cases are cited therein from
unusual reports, the 0. G. citations are given herein.
It is too much to hope that everyone will be satisfied with the group-
ing of the cases. An attempt has been made to cite all cases on obscure
points, and on leading points to cite all important cases together with
those cases which contain many citations. The work covers 242 U. S. ;
237 F. R. and 235 0. G.

TEXT.
The intention of the patent law of the United States is to give a
monopoly for seventeen years to the inventor or discoverer of a new art
or a new utility in any substance, structure or piece of machinery. The
inventor is required to publish a brief, clear description of his invention
and to carefully define it (viz: claim it), so that anyone may at any time
find out whether he is infringing on the rights of the inventor. Of
course in carrying out this law many practical difficulties arise. It is, for
example, often difficult to decide how far a definition or claim can be
pushed in covering items substantially the same from one point of view
though they differ in other ways. Then, too, the definition must cover a
distinct step in advance and not something that is simply better but not
otherwise new ; further, the definition must cover the real invention and
not a mere application of it.
It is obviously impossible for the Patent Office or the courts to ex-
amine every workshop, laboratory and factory, so in judging whether
the improvement is really new it is necessary to take such published
data as are available and decide from these whether the applicant for a
patent has shown such an improvement as any skilled mechanic or ex-
pert in the art might be expected to have extemporized, or whether it
is more than that and so deserving of a patent. In facing these difficul-
ties and the analogous ones that arise in determining the scope of an
invention, etc., the courts have laid down certain fundamental princi-
ples, such as that it is not patentable1 to put an old machine to a new
use; that an abandoned experiment2 cannot defeat a later patent; and
that where an improvement goes into extensive use from its own3 merits,
a patent allowed on it must almost certainly have been justified.
Every patent (except for design patents) is directed either to an
"instrument" or to an "operation," the "instrument" being either a
machine, a "manufacture" (such as a structure which has some physical
utility), or else a composition of matter, (though this last is really only a
specific form of manufacture). Every chemical patent properly so
called seems to be directed either to an " operation ' ' per se, or else to an
"instrument" whose patentability depends on its relationship to an
operation in or on material outside itself, e. g., a dye.

CHEMICAL PATENTS
In addition to what are strictly chemical patents and "operation"
patents there are many analogous patents out of which problems arise,
more nearly allied to chemical and "operation" patents than they are
allied to strictly mechanical patents. Such a problem was presented by
the British patent covering easily fusible tubes of water within the
hollow walls of safes to increase their resistance to fire. This was held
infringed* by a hollow safe wall filled with alum which gives off water
when heated. Such problems obviously call for expert testimony,5 as
do most chemical patents.
Almost all patents, therefore, may be divided into two classes, first
those in which patentability turns 011 mechanics6 in its restricted sense
(viz : the mechanics of rigid bodies and machines) , and secondly those in
which7 patentability turns on chemistry or on electrical or molar physics
(viz: the physics of masses of matter, such as the flow7 of liquids8 etc.).
Though the distinctions9 between processes and "manufactures" and
machines are sometimes10 vital, and from a strictly philosophical point

of view always11 exist, yet the present writer believes that in practice it
is impossible to define the lines of distinction so that the definition will
be of universal practical utility in patent law. The difficulty of drawing
such lines and the unreasonableness of attempting to deduce them from
the decisions of the courts lies largely in the fact that patentability de-
pends on utility, bearing in mind that utility means "industrial12 value,"
and this utility may be defined either by the13 product or the14 result of
the machine or process,15 or by the adaptability of the * ' manufacture ' ' to
cooperate with something16 else, or it may depend on the coordination of
its parts among themselves.
The claims of a United States patent, in the case of most machines
and many processes (including chemical processes), may well be re-
garded as definitions of the parts of the invention in terms of their abso-
lute17 industrial value, viz: in terms of the function they contribute to
the elements with which they are associated; but in the case of many
manufactures (for example textile fabrics) and compositions of matter,
the claim merely recites the novel useful elements. Now since the indus-
trial value of an invention may be often approached from more than
one point of view it seems obvious that a claim may on its face cover
line, 30 F. E. 871. Where the invention
lay in using an old skein in a novel way,
a claim to the skein is void. Grant v.

only a machine, but depend for its validity on, and have its scope de-
termined by considerations which are not mechanical.18 Again, for
example where a novel elasticity is obtained in a knit fabric, it may be
impossible to state whether the invention lies in the fabric itself, or in
the method of forming it.
Many considerations must determine from what point of view a
claim should be drawn, since on the one hand a process claim is not in-
fringed by the selling of the product19 of the process, while on the other
hand situations arise like that in which an inventor patented a special
form of skein which he devised for use in dyeing, but the patent was
held void because the skein turned out to be old, though its use in dye-
ing20 was new.
The subject of the relationship of processes, products, machines, etc.,
is further complicated by the fact that the courts usually construe
patents liberally in the21 endeavor to give adequate protection to pat-
entees who are relying on imperfectly conceived and badly constructed
specifications and claims.
The present writer realizes that it is impossible for him to include
every case which turned on considerations having their basis in facts
which are primarily chemical in their nature, or which belong with
chemical facts, largely because such facts frequently do not appear on
the face of the decision. Besides this there will be some disagreement
as to what constitute such facts. It is believed, however, that the cases
cited herein cover almost every pertinent point.
The present writer feels sure that if the same attention were given
to specification planning22 and writing as is often given to claim draft-

ing, much expensive litigation would be avoided, for the patentability of
claims and the correctness of the underlying theory of the specification
can often be made so obvious as to render it useless to attack them in
court. Solicitors often forget that theoretically the specification is not
addressed to lawyers, but to those skilled in the art, and must at least
set forth real and fundamental facts of the invention, and not merely
irrelevant observations, however new and interesting the phenomena23
may seem to be at the time.
Specification writers often forget that any process and composition
claim is void if the steps or ingredients enumerated in the claim are
less24 than those which the specification makes essential ; and that, in the
same way, if a given device or limitation is essential, according to the
specification, one who does26 not use it is not an infringer. But, while
claims are limited by the statement of invention, they are not limited by
the examples given, and may be much26 broader than such examples.
Many a patent has been rendered worthless by failure of the speci-
fication writer to include a careful detailed description of how the
process, etc., might be carried out, apparently through fear lest such a
description might be construed as a necessary limitation of the claims.
Specification writers seem to forget that such a description is strictly
analogous to the drawings of a mechanical patent, and if properly
worded need never constitute a limitation.

CHEMICAL PATENTS
The question of joint27 inventorship of processes, as set forth in the
decisions, is difficult to reconcile with analogous decisions on machine
patents.
Patents which seem to be mechanical method patents, are apparently
very rare except in arts like the textile art, where elasticity and other
obscure properties often are vital, so that the mechanical methods of
kniting, weaving, etc. have a profound but not easily28 foreseen effect
on the product.
A process is independent of a given form of machine, though some
processes appear to be necessarily performed only by a given machine at
the time29 of patenting. The patentability of processes which are pri-
marily mechanical is extremely difficult of definition30 and usually can-
not be decided on the31 face of the patents. Apparently a series of steps
is patent able if its32 utility overcomes a hitherto insuperable obstacle, or
depends on an idea which has previously been thought33 preposterous, or
depends on some hitherto unsuspected possibility in the34 materials used.

A method of assembling a ball bearing having both, inner and outer
races integral was held35 patentable, though putting an old seam in a
difficult place was held not to be a patentable36 process. Mere transpo-
sitions of the material used to another part of a machine operating on
them does not make a patentable37 process.
The result which was hitherto38 unattainable will confer patent-
ability on the process which produces the new result, even if that result
or utility is only in enabling the product to be obtained at less39 cost and
in less time, though the new result or utility must be revolutionary, and
not merely better.
It seems generally agreed that a process which involves a new se-
quence of chemical or mechanical steps, or an electrical operating system,
is40 patentable if the result differs greatly from that produced by the old
order of steps or organization, either in increased41 efficiency of work, or

chine instead of hand, is50 not patentable unless a different51 kind of
result is obtained, and not merely62 increased or beneficial result.
A process of preserving fish which turned on the discovery of the
properties of an inner skin was53 patentable, whereas a process of baling
cotton which was based on a false theory54 was held unpatentable. A
process of making oils or heating them in an old way till they answered
to a certain flash test was held55 patentable, but on the border line of
patentability.
Perhaps the clearest discussion of unsuspected properties as a test
of novelty is found in the decision on the steel tempering patent which
was held56 void on the theory that the alleged novelty merely consisted
in carrying forward an old idea to increase an old result. It should be
noted that the court held the patent 'would have been valid if the carrying
forward of the patented process to a less degree would have produced a
result which differed from the old result in57 nature rather than in de-
gree only. Some analogous decisions will be found in connection with
electrical58 patents.

In other arts it is held that builders house interior finish prepared
elsewhere is not59 patentable over the ordinary finish* built in place. So
using a "predetermined" quantity or properly "regulated"60 quantity
is not a patentably new process so far as definition by such phrases is
concerned.
While the result obtained, often is controlling61 in deciding patent-
ability, a process even though producing a tangible product often is
patentable though its product is not62 patentable, or apparently not
new and63 vice versa. So a process may be patentable although
all its steps are old if the new sequence or bringing the processes64
together produces a new or improved65 result. Omitting a step pre-
tors which depends on a hitherto unuti-
lized though known principle, is patent-
able and construed broadly. Westing-

CHEMICAL PATENTS
viously thought66 necessary may be patentable. In other words each
step must be considered in the light of other67 steps and not if it stood
alone. Infringement likewise will be found where there is a mere68 re-
arrangement of steps provided this rearrangement of steps does not de-
pend on a new theory of operation.
The wording of a specification may be controlling, however, in de-
termining the identity69 of processes and of analogous inventions, espe-
cially electrical70 inventions. It is worth noting that very few patents
have been held to be "aggregations"71 where any chemical step was as-
serted to be a novel feature of the process, or the ingredients of a com-
position had any chemical relation to each other. A method of book-
keeping72 or advertising or doing business seems to be unpatentable, but
slight "manufactures,"78 or mechanical aids to bookkeeping have been
held patentable even when the utility largely depended on the fact that
these aids were of mental utility.

Under the United States patent laws it seems settled that merely
utilizing waste material is not74 patentable unless the steps in such
utilization are patentably new in themselves. Such a holding is prob-
ably a development of the doctrine that it is not patentable to apply an
old78 process to material analogous to that formerly used in the old
process ; or use analogous materials76 on an old substance.

CHEMICAL PATENTS
A process is not patentable till means have been invented capable of
carrying it out, and these means must be obvious from the prior art or
adequately described in the77 specification. All claims must be based on
the nomenclature of the78 specification and the tests set up therein are
vital. Conversely a process patent is not anticipated merely because a
/device79 existed, and might have been used to carry it out, or by a
machine incapable of completely80 carrying out a process, or by a de-
scription unless the description is81 clear and exact enough to enable

does not really exist till reduced to practical84 form, ncr until the
utility86 of the result is realized. If, however, the process has been de
facto practiced regularly, even though86 accidentally, it is anticipated.
Perfect operation, however, is not necessary to give validity to a specifi-

prove94 identity of process.
The question of identity of invention, therefore, and of scope of
claims and disclosures comes up in several forms, one interesting form,
though almost impossible to draw valuable broad conclusions from, being
the relation of the United States to the foreign95 patents of the same in-
ventor.
Double96 patenting has been ruled on in some cases, but is still too
unsettled a question to discuss briefly and broadly, aside from the inter-
relation of process, product and machine. Where an inventor has both a
process and an apparatus application pending, abandonment97 or restric-
tion of one will not effect a patent granted on the other and the same
holds true with the relation of98 foreign to U. S. patents. It is, of course,
agreed that while a process invention is a different invention from a
machine invention, a process patent must differ from a machine patent
more than in substituting99 the word "method" for the word "means."
It has been held that a machine patent may be reissued, or have claims
added to it while still pending100 to cover a process, or a process patent
identical as elements in two claims of one
application. Ex parte Ach, 96 O. G.

CHEMICAL PATENTS
can be101 reissued to cover a machine though the decisions are conflicting.
Separate patents for an electric motor organization102 and for method
of operating the motors even when apparently dependent on the appa-
ratus have been held valid. It has been held that where a machine
patent issues, a process103 patent covering the machine may be valid if
applied for a less than two years after the machine patent issues. It has
been held that a process patent cannot be reissued to cover a product
and104 contra; the same holds true of reissuing105 product patents to
cover processes. Analogous facts also hold true as to the adding of
claims106 to pending applications. It would seem that since the Courts
have had to face specific problems, they have endeavored to settle each
case on its merits, irrespective of a purely philosophical view of patent
law.

question which depends both on common knowledge and on special facts
in the application. This kind of point of view hashed one Court to go so
far as to say in the Adrenalin108 case, that they were not prepared to
hold synthetic adrenalin would infringe a claim to extracted adrenalin.
A process is not infringed if any claimed step or ingredient is109
omitted and no equivalent110 substituted therefor. But avoiding the
terms of the claims does not avoid111 infringement when the process is
really the same. The same is true of ingredients of112 compositions.

arts or processes. The claims, however, must be read in the light of
the117 specification. Adding a new step does not avoid infringement if
the118 theory remains the same. Especially must reliance be placed on
the theory of operation in questions of119 infringement of process parents
where other tests are difficult to apply, as where the defendants120 fail
to completely disclose their process. The same considerations apply
conversely among others when the question of121 contributory or di-
rect122 infringement of process patent is raised by the selling of a ma-
chine or manufacture123 or composition or apparatus usable for the
process. Infringement also may be charged though the infringement
was possibly124 accidental in details, if those details contributed to the
result. Infringement also is found where goods partly processed when
purchased are completed125 according to a patented process.

CHEMICAL PATENTS
Infringement damages are computed both on the basis of profits126
to the infringer and127 damage to the patentee, but only cover the
product of128 the patented process. The using or vending of a composi-
tion of matter infringes129 a patent for it, and where an article is made
wholly of patented composition130 the damages are the entire profits.
In interferences the questions are much the same as in infringe-
ment and novelty, both as to steps and ingredients added or omitted,
But the proof of the infringement, anticipation, and laches, etc., in con-
nection with something intangible, like a process131 is often somewhat

Moreover interference in fact is not132 proved by ability to copy claims.
There is no interference where the claims of133 one party include an im-
portant step not in the claims of the other, or a134 product not made by
him. The prior inventor of a process is held prior135 inventor of its
product. The question of inventorship, as between a suggester and a

tion as to whether an experiment138 in a laboratory has the standing of a
model or of a working machine in mechanical patents appears to depend
on special circumstances, but a139 caveat was a reduction to a practice if
full and complete.
The important question of140 licenses has comparatively rarely come
up, in connection with decisions on process or composition patents, ex-
cept on questions which are broader than the scope of this essay. As
in the case with mechanical patents, the licensee often gets more privi-
leges than the face of the license seems to call for, because the licensor141
is presumed to give something of real value. The licensee of a process is
owner142 of the product and can do what he likes with it, but ownership
of a patented machine is no143 license to use it or to buy others to use in
a patented process.
The construction of claims144 is strictly limited to what they cover.
A single claim cannot cover both a process145 and machine or

product.146 Claims to chemical inventions are not so strictly147 limited
in form as those to mechanical inventions since the absence of substances
can148 constitute invention and be149 claimed. The claims must not, how-
ever, be limited to a mere150 result. A process claim must not be to the161
mere "use" of a thing or ingredient. Amendments to claims are, how-
ever, just as binding152 as in machine applications.
Owing to the point of view of the U. S. Courts and U. S. Patent
Office there is a natural tendency to require inventors to define prod-
ucts153 independently of the process by which they are made, and154
processes independently of products. This leads to some unfortunate
results and is155 often abandoned owing to the fact that patents often
turn on empirical chemistry156 and mechanics, so the claims must be
formulated before theoretical chemistry and mechanics can supply ade-
quate definitions. It seems likely that less pressure will be used in the
future in limiting claims in this way.
It is unfortunately apparently necessary to insist that the inventions
in process and product patents must be167 definably new and be claimed

by such definitions158 even though the reasons for selecting a given defini-
tion are not wholly clear. A manufacture or product thereof is not159
patentable because made by a better machine, or better process.
A coating has been held properly patentable160 as such. A product
is sufficiently defined161 if claimed as ' ' coated substantially as described ' '
or having the "herein described characteristics." A product may be
patentable because of its162 utility even if merely purer or in more163
useful form than the prior art shows. Similar facts are true of manufac-
tures.164 A product patent will cover165 equivalents even though not166

ferent168 process. A product is not novel if a description169 of a process
has been published, if that necessarily produced the product. The kind
of170 utility residing in a product may be controlling as to the question
of infringement. It follows from what has been said above that it is
impossible to lay down any controlling rule for deciding whether it is171
process or172 product which is patentable when one is obvious the other
given. This is analogous to the fact that a machine may be173 patentable
though its structure is obvious once the problem is stated which the
machine solves, though patentability often resides in the machine itself.
A product may be patentable because it has hitherto been unattainable,
but a new process174 makes it available ; and where a process and product
are claimed in a single patent and are both infringed, the courts often
hold the product176 claims good as a matter of course when the process
is new.
The doctrine of equivalents is often difficult of application in com-
position patents and some confusion exists as to the meaning of the dic-
tum that a newly discovered176 substance cannot be construed as an equiv-
alent in infringement suits. An equivalent of a substance is another hav-
ing substantially the177 same effect to be determined by appropriate tests

of ingredients. No composition is novel within the meaning of patent
law which is merely made of182 better materials and which is only such a
composition as a physician or expert183 in the art might be expected to
prescribe or devise; nor one which is an184 artificial matching of a
natural compound. Similar considerations control the question of in-
fringement185. Thus a patent will not be construed to cover a composi-
tion not within its terms, and only accidentally186 nearly equivalent. So
it follows that a really novel composition cannot be rejected on an aggre-
gation187 of references though a new composition may infringe188 an old
one, but the mere discovery of new properties in a composition or manu-
facture189 otherwise old does not make it patentable. Broad names in a

AND ALLIED PATENT PROBLEMS. 39
avoiding the terms of the claim but attaining the same unexpected209
utility. So the fact that structures are integral210 does not ordinarily
make them patentable, but the question of analogous211 arts in this
question and with reference to other manufactures, is one on which it
seems impossible to lay down any broad principle not varying with the
meaning of the phrases ' ' analogous art ' ' and ' ' common knowledge. ' ' An
article devised so as to be made by machinery is not212 patentable where
a similar one was hand made.
In the interest of equity a given fabric is held not patentable when
a213 patent exists on a tire made from the fabric, and a coated paper is
not patentable when a patent exists for coating whose214 primary use
is to make the same paper. Here of course identity of invention is ap-
parent, whereas the paper bag making process216 patent the machine
and process were held absolutely independent.
Patent Office216 practice is often severe compared with Court prac-
tice, but this is often justified because an applicant has many remedies
while his application is pending, but almost none, except a hazardous re-
issue, after his application is patented. It is now held that where217
process and apparatus are mutually dependent they may be joined in one
application? but usually218 not otherwise, but the whole matter lies in the
discretion of the Office which may sometimes permit a process, a product
and a machine to be included in one application219 and also a

CHEMICAL PATENTS
function, or when it fails to state any industrial utility of the invention
in terms of the environment to which the invention contributes the new
function. The question of what is "new matter"240 in a process or com-
position application is obscure in view of the wording of the statute.
' ' Substantially as described ' ' is241 sufficient definition in a claim.
Verbose and indefinite242 specifications and closely parallel243 claims
are just as objectionable as in mechanical patents, so also are nebulous
claims, arid claims which are not clearly directed to244 either a process
or composition or a manufacture, and therefore are indefinite but245
extra descriptive matter in claims may be ignored by the Examiner.
