OPINION OF THE COURT

WEIS, Circuit Judge.

Changing the discharge point of a concrete mixer
from the rear to the front of the truck results in definite
advantages but does not raze the roadblock of nonobvi-
ousness required for patentability. We therefore re-
verse a district court finding of patent validity. We find
jurisdiction also to review a companion count alleging
con\ersion of trade secrets related to the construction
of concrete mixers. Because that claim contains dis-
puted matters of fact, we vacate a summary judgment
centered in favor of the defendant.

By. virtue of an assignment in 1965, plaintiffs R. W.
Sims, Trustee, and the R. W. Sims Trust hold U.S. Pa-
tent No. 2,859,949 issued in 1958 to J. Jack Willard fora
front-discharge concrete mixer. The pending action is
based on allegations of infringement by defendant and
an additional count of unfair competition. The district
court entered summary judgment in favor of the de-

fendant on the unfair competition count on February 9,
1978.' : :

1. For reasons not here relevant. plaintiffs’ unfair competition
claim appears in two separate lawsuits. In Civil No. 75-985, the
case that we are entertaining on appeal, the unfair competition

A- 3

After a bench trial, the district judge upheld the
patent, found that the defendant had infringed, and
awarded double damages to the plaintiff, but denied
attorneys’ fees. The defendant appeals the infringe-
ment issues under 28 U.S.C. §1292(a)(4). Plaintiffs
cross-appeal the denial of the attorneys’ fees and seek
review of the summary judgment on the unfair compe-
tition claim.

The Willard patent describes a concrete mixer
mounted on a truck chassis and used to deliver pre-
mixed concrete to a construction site. The more com-
mon truck in general use unloads the concrete from the
rear. The Willard design, however, reverses the mixing
drum so that its narrow discharge end is at the front
rather than the rear of the truck. The drum is inclined
upward toward the front so that the pour end is above
the driver’s cab. A portable chute is used to move the
concrete from the dium to the particular spot where
the construction is in progress.

The great advantage of the front-end discharge is
that it allows the truck to be driven directly to the place
where the concrete is to be poured without the neces-
sity of backing into the area, as is required with vehi-
cles of conventional configuration. Thus, the dangers
of backing to the unloading site are eliminated, and by
maneuvering the truck the driver can assist in the ac-
tual pouring of the concrete. In a modification added by

claim is Count II of a two-count complaint, the first count charging
defendant with patent infringement. In Civil No. 76-2070, the un-
fair competition claim comprises the only count of the complaint.
By opinion dated February 8, 1978 and orders dated February 9,
1978 and April 18, 1978, Judge Lord dismissed this claim as found
in both complaints. See Sims v. Mack Trucks, Inc., 444 F.Supp
1277 (E.D. Pa. 1978). Civil No. 75-985 then proceeded to trial on
the patent infringement issue. After the trial, plaintiffs appealed
from both dismissals, with the appeals filed October 13, 1978. No.
78-2518 is Sims's appeal as to Civil No. 75-985. Nos. 78-2519/20 are
the appeals from Civil No. 76-2070. Clearly, the appeals from Civil
No. 76-2070 (Nos. 78-2519°20) are infirm because plaintifts failed
to comply with the 30-day time limit of Fed. R. App. P. 4.

plaintiff Sims, the driver may sit in the cab and shift
the chute by means of hydraulic controls.

Willard first applied for the patent on July 18, 1955,
but it was not granted until 1958. On November 14,
1955, Evan S. Pritchard filed an application for a
front-discharge mixer of similar construction. In 1958
plaintiff Sims also considered applying but decided
against it when he learned of Willard’s patent. At first,
the Willard truck met with little commercial success,
and in 1965 it was assigned to the Sims Trust. Thereaf-
ter, plaintiffs successfully marketed licenses to a
number of manufacturers.

Defendant considered the possibility of manufac-
turing front-end discharge trucks in 1963 and met with
Sims at that time to discuss a possible licensing ar-
rangement. Although Sims was not at that time the
holder of the Willard patent, Mack’s interest in him
was aroused by his development of one of the first
technically and commercially feasible front-discharge
mixers. After some study, however, defendant decided
not to cnter the market. In late 1972, defendant con-
ducted a new market survey and concluded that it
should reevaluate its position. The following year, de-
fendant modif.ed an existing chassis to accommodate
a front-discharge mixer and in the next four years sold
a number of chassis, some with the mixer attached.
Although the record does not establish when those
transactions took place, it does reveal that defendant
exhibited a front-discharge mixer in two trade shows
before the patent expired in 1975.

In a detailed and scholarly opinion,” the district
judge concluded that the defendant had failed to prove
obviousness. Recognizing that the front-discharge
mixer concept was a combination of known compo-
nents, the court nevertheless determined that because
of the combination’s “synergistic” effect, the patent

survived the required close judicial scrutiny. In re-
sponse to defendant's contention that there was no in-
fringement because the mixer drums mounted atop the
Mack truck chassis were purchased from a licensee,
the court ruled that Mack had waived the license de-
fense by not pleading it in its answer. Double damages
were determined to be appropriate because the defen-
dant willfully infringed, but since the defenses of inva-
lidity and noninfringement were colorable and non-
frivolous, counsel fees were denied the plaintiffs.

VALIDITY

As its principal defense, Mack contends that the
Willard patent was invalid on the ground of obvious-
ness, 35 U.S.C. §103. We turn to that issue first.

The courts have long adhered to the principle that
patents are not to be issued for every device effecting
some improvement, but only for those that may be
called “inventions.” The problem of separating the two
was recognized early by Jefferson, whose duties as
Secretary of State included administration of the pa-
tent system. It was his belief that the limited monopoly
sanctioned by the Constitution should be construed
narrowly: “Only inventions and discoveries which
furthered human knowledge, and were new and use-
ful, justified the special inducement of a | mited pri-
vate monopoly.” Graham v. Jolin Deere Co., 383 U.S.
1, 9 (1966) (discussing Jefferson's \iews).

In Hotchkiss v. Greenwood, 52 U.S. 248 (1850),
the Supreme Court, in one of its first expressions of this
sentiment, said that if “that degree of skill and in-
genuity which constitute essential elements of every
invention” were absent, the improvement would be
only the “work of the skilful mechanic, not that of the
inventor.” Id. at 267. Attempts over the next hundred
years, however, were unsuccessful in producing a
workable definition of invention, and in the 1952 Pa-

valid and was infringed under the doctrine

ture and sale of chassis for front-discharg-

OPINION
JOSEPH S. LORD, III, Chief Judge.

Plaintiffs, a family trust and its trustee,
brought suits for patent infringement and

$: &£.
=

for unfair competition based on defendant’,
manufacture and sale of chassis for fron.
discharge concrete mixers. We granted dc.
fendant’s motion for summary judgment a:
to the unfair competition claim but denieg
the motion as to the patent claim, 444
F.Supp. 1277 (E.D.Pa.1978). Three issues
were tried before me: the validity of th.
patent in suit under 35 U.S.C. § 103; jn.
fringement of it by the defendant under 35
U.S.C. § 271; and, if there was infring,.
ment, whether the willfulness of defend.
ant’s conduct calls for increased damages
under 35 U.S.C. § 284. I now make the
following findings of fact and conclusions
of law:

FINDINGS OF FACT

I. Background:

1. The plaintiff R. W. Sims is an individ.
ual who is the sole trustee of the plaintiff
R. W. Sims Trust, a trust organized under
Utah law whose beneficiaries are R. W.
Sims, his wife and their four children.

2. The defendant is a corporation which
is incorporated in Pennsylvania, has its
principal place of business in Pennsylvania
and is engaged in the manufacture of
trucks.

3. The patent in suit is United States
Patent No. 2,859,949, issued on Novemlwr
11, 1958, to J. Jack Willard for a Forward
Discharging Transit Concrete Mixer (the
“Willard patent”) (Fig. 1).

SIMS v. MACK TRUCKS, INC. 1201
Cite as 459 F.Supp. 1198 (1978)

4. A self-transit concrete mixer is a
truck with facilities for receiving, mixing
and transporting concrete and for discharg-
ing concrete at the site where it is to be
used. The construction disclosed in the
Willard patent is a fully operative front-dis-
charge self-transit concrete mixer, although
its operation could be and later was im-
proved by altering that structure.

5. R. W. Sims in 1958 designed and con-
structed a front-discharge self-transit con-
crete mixer and sought to have it patented.
When his counsel's patent search disclosed
the Willard patent and he learned that his
construction would infringe the Willard
patent, he entered into negotiations with
the patentee.

6. In order to continue to make, use and
sell front-discharge mixers, Sims entered

into a licensing agreement under the Wil-
lard patent. In 1965 Willard assigned to
the plaintiff trust all rights under the Wil-
lard patent.

Il. Validity:

A. The Prior Art

7. In 1955 the prior art of self-transit
concrete mixing trucks included a rear-dis-
charge mixer, with a drum on a fixed longi-
tudinal axis inclined upwardly toward the
rear. This construction is disclosed in, inter
alia, United States Patent No. 2,661,935,
issued on December 8, 1953, to Carl L. Wil-
lard, and United Siates Patent No. 2,672,-
327, issued on March 16, 1954, to John F.
Oury (Fig. 2).

In these trucks the concrete mixing drums
are filled with concrete through their rear
ends. The drums are rotated in one di-
rection to mix the concrete and in the oppo-
site direction to discharge the concrete
through their rear ends.

8. The prior art in 1955 included a sepa-
rate attachment to a tractor for mixing,
transporting and discharging concrete, dis-
closed in United States Patent No. 2,706,-
623, issued on April 19, 1955, to Fred J.

., Styes. In this construction, the concrete is

carried in a small mixing drum forward of
the tractor connected to it by sidebars.
These bars can swing from their point of
attachment either to extend the mixing
drum downward and forward of the tractor
for loading or to lift it up, like a car of a
ferris wheel, for discharge.

9. The prior art in 1955 included a self-
transit concrete mixer which could be load-
ed from the front of the mixer, disclosed in
United States Patent No. 2,327,473, issued
on August 24, 1943, to Harold A. Wagner
and Gustave H. Wagner. In this construc-
tion, a loading device is attached to the
truck chassis by arms. When those arms
are extended forward, the loading hopper is
on the ground and can be loaded. Those
arms can be rotated, lifting the hopper over
the cab, again like a car of a ferris wheel.
When the hopper is over the cab it can be
emptied into the front part of the drum.
This truck provides for the discharge of
concrete through the rear end.

10. The prior art in 1955 included a
chute to control the discharge of concrete
from self-transit mixers, disclosed in United
States Patent No. 2,045,532, issued on June
28, 1936, to John C. Merwin and Charles F.
Ball, and in the Oury patent. The Oury
cylindrical chute is attached to the side of
the mixer for transport and can easily be
placed at the discharge end of a mixing
truck and positioned so as to control the
flow of concrete from the drum to the area
where the concrete is to be distributed,
while the Merwin chute is a similarly placed
open trough.

11. The prior art in 1955 included mech-
anisms for driving mixing drums on self-
transit concrete mixers disclosed in United

States Patent No. 2,729,435, issued on Janu-
ary 3, 1956, to Henry C. Harbers and Ed-
ward D. Sharpe. These mechanisms are
illustrated in the patent by use with a rear-
discharge mixer.

12. The prior art mentioned in $4 6-10,
with the exception of the Merwin chute,
composed the references cited by the Unit-
ed States Patent Office in the Willard pat-
ent file. Of these, only the patent issued to
Styes discloses a concrete mixer which dis-
charges concrete in front of the vehicle.
The construction in this patent was limited
in its use to tractors using small amounts of
concrete, however, and was not adaptable
to full-sized self-transit concrete mixing
trucks.

13. The prior art in 1955 included a con-
crete mixing drum with helical blades, dis-
closed in United States Patent Reissue 23,-
$20, reissued on January 2, 1951, to Carl L.
Willard and J. Jack Willard. - This‘device is
a concrete mixing drum in the shape of a
cylinder with a frustum at each end con-
structed so that the material in the drum is
mixed by rotating the drum in one direction
and discharged out of one end of the drum
by rotating the drum in the other direction.

14. The prior art in 1955 included a rear-
discharge concrete mixing truck with a
mixing drum which has a non-inclined hori-
zontal axis but which can be inclined in the
rear to effect higher discharge, disclosed in
United States Patent No. 1,998,749, issued
on April 23, 1935, to Charles F. Ball. In
this construction the mixing drum did not
have a fixed longitudinal axis but rather
one which could be varied in order to meet
the needs of the discharge on a particular
job. This patent was not cited as prior art
in the Willard patent.

15. The prior art in 1955 included a con-
crete mixing truck which discharged con-
crete out of the front of a cylindrical drum
by tilting the drum forwardly and allowing
gravity to induce the discharge, disclosed in
United States Patent No. 1,509,055, issued
on September 16, 1924, to Charles Payne
(Fig. 3).

Fig.

The construction disclosed in this patent
appears to be the only one providing for
front discharge of concrete in a full-sized
self-transit mixer before the Willard pat-
ent. In this construction, the concrete is
loaded into the cylindrical drum through
the top of the cylindrical drum, which has a
non-inclined horizontal axis during the load-
ing and mixing of the concrete. At the
time of discharge, the driver in the cab at
the forward end of the vehicle operates a
lever which causes the rear end of the drum
to be raised and the forward end to be
lowered, giving the drum an axis upwardly
inclined from front to rear and inducing the
concrete to slide out the front of the drum,
with discharge under the driver's position.
The Payne patent provides for discharge
into a portable concrete distributing cart,
which in turn would be used to apply the
concrete. The Payne patent, which was not
cited by the United States Patent Office as

Prior art in the Willard patent, was among

Prior art most pertinent to the Willard
Patent because it embodies a front-di
charge self-transit mixer.

16. The prior art included in 1955 self-
transit mixers with non-inclined horizontal
mixing drums which discharged concrete
out the rear ends of the mixing drums by
tilting them, much as the Payne patent did
in effecting front discharge.

17. Most of the self-transit concrete
mixers in use in 1955 were rear-discharge
‘self-transit mixers with drums of fixed axis
upwardly inclined toward the rear or dis-
charging end. These trucks had certain
disadvantages in their operations. Among
these were the slowness of discharging, in
that the truck had to be backed up to the
point of discharge and the driver often had
to leave the cab in order to ascertain where
the concrete would be discharged, so that at
least two persons were needed to operate
the truck when the point of discharge was
being varied slightly, one person to drive
the truck and the other or others to observe
the point of discharge and instruct the driv-
er; and the high rate of accidents caused by
the driver’s inability to observe the dis-
charging end and chute.

A- 24

1204 459 FEDERAL SUPPLEMENT

18. There were also in use in 1955 rear-
discharge mixers of the type disclosed in
the Ball patent which inclined the mixing
drum in the rear in order to achieve a high
point of discharge, which is advantageous in
some situations. These mixers shared the
disadvantages of rear-discharge self-transit
mixing trucks generally. There were also
in use in the 1950's “dumper” self-transit
mixers like the construction disclosed in the
Payne patent, but they were subject to
frequent breakdowns and like rear-dis-
charge mixers with fixed drums required at
least two persons, a driver and someone
stationed on the ground to operate the sep-
arate concrete distributor.

19. The rear-discharge mixers which
dominated the self-transit mixer market in
the 1950’s had their weight concentrated
over the rear wheels. This concentration
made it difficult and dangerous to dis-
charge concrete into an excavation or on
soft ground because the heaviest part of the
vehicle had to be near the point of dis-
charge.

B. Differences Between Prior Art and
the Patent In Suit

20. The Willard construction provides
for front discharge of concrete by inclining
the bowl upward toward the front, rather
than rearward as is the case both in the
rear-discharge mixer with a drum of fixed
longitudinal axis and in the “dumper” mix-
er of the type disclosed in the Payne patent.

21. The mixing drum employed in the
Willard patent is of the type disclosed in
United States Patent Reissue 23,320,» per-
mitting mixing and discharge by the rota-
tion and counterrotation of helical blades.
The shape of the drum is generally similar
to those disclosed in the prior art, i. e., a
cylinder and a frustum with the cylinder
further from the loading and discharging
end, but in the Willard construction there is
adjacent to the frustum a drum extension, a
relatively narrow cylindrical section at the
discharging end. This drum extension is
somewhat analogous to the narrowed part
of the drum at the discharging end of the
cylindrica! drum in the Payne patent. At
the discharging end of the drum extension
in the Willard patent there is a discharging

chutc, similar to those revealed in the prior
art, which is supported by a bracket and
chain. Like the chute disclosed by the Oury
patent, this chute is removed from its dis-
charging position and carried on the side of
the unit during transit.

22. As a result of providing for dis-
charge at the front end of the unit, inclin-
ing the drum forwardly, providing a drum
extension which is elongated and narrowed
relative to the frustum adjacent to it and
placing a chute extending forward at the
poirt of discharge, the Willard patent per-
mits the point of discharge from the chute
to be in the view of the driver of the unit
when he is in the cab. Because front dis-
charge is achieved by having the drum dis-
charge above the cab, rather than under it
as in the Payne patent, the advantage of
high discharge is retained in the Willard
construction.

23. The construction disclosed in the
Willard patent has a number of advantages
over the rear-discharge mixer which domi-
nated the self-transit mixer market as of
1955. Most of these stem from the driver's
ability to observe the discharge from the
cab and therefore to be able to see the point
where concrete is being discharged without
leaving the cab. As a result of this visibili-
ty, the driver of a Willard unit is able to
vary the point of discharge while remaining
in the cab. Furthermore, the driver is able
to drive forward to the proper point of
discharge and bring the point of discharge
to it in the first instance without getting
out of his cab or relying on other persons’
instructions, as is often necessary in rear-
discharge mixers where the driver must
back into the point of discharge. In addi-
tion, the danger that the driver would drive
onto a surface which was unable to support
the truck or into construction forms with-
out observing the nature of the surface is
reduced significantly by the Willard unit.
Furthermore, this construction potentially
would reduce the high rate of accidents in
rear-discharge mixers on account of the full
visibility to the driver of the discharging
chute and discharge operation.

24. By extending the mixing drum
roughly from the rear axle to the forward
axle, the Willard construction distributes
the weight between the axles more evenly
than the rear-discharge mixers in use at the
time of its invention.

25. Because the Willard construction
distributes the weight of the vehicle more
evenly between the front and rear axles
and because of the forwardly protruding
discharging chute, the Willard vehicle is
able to discharge near soft ground or a
excavation more safely than a rear-dis-
charge mixer.

26. Relative to the dumper type of self-
transit mixer disclosed in the Payne patent,
the Willard construction has three types of
advantages. First, by incorporating the
mixing drum with helical blades which had
been developed since the Payne patent and
had come to dominate the market by 1955,
it incorporates all the advantages of those
drums over the more cumbersome and more
fragile cylindrical drums and tilting mecha-
nisms of the dumper type of mixer. In
addition, the Willard construction permits
the driver to see the point of discharge of
concrete onto the place where it is being
used, with all the advantages which accrue
from that visibility, whereas in the Payne
patent it is claimed only that the driver is
able to observe the discharge into a sepa-
rate unit used for concrete distribution.
The Payne patent does not disclose whether
discharge to the point of application itself
can be observed by the driver, but its fail-
ure to claim that advantage and the place-
ment of the discharging end of the drum
relative to the cab make it appear that
there would not be such visibility. Finally,
the Willard construction maintains the ad-
vantages of high discharge, which is impos-
sible in a dumper-type self-transit mixer.

C. Level of Skill In the Relevant Art

27. There was little evidence presented
at trial as to the general level of ordinary
skill possessed by those involved in the de-
sign of self-transit mixing trucks. The
Plaintiffs presented evidence through the
testimony of R. W. Sims and that of an
expert, Robert W. Fay, suggesting that de-
signers of such vehicles were unable to

solve the problem of delivering concrete
efficiently, quickly and safely and that
progress in the industry was through 1955
very slow. The art was characterized by
several witnesses as an active one during
the early 1950's in spite of the fact that
there were no striking advances made.
Most of the evidence which related to the
level of skill in the art of self-transit mixer
design, however, involved only the narrow
conclusion that persons of ordinary skill in
this art would or would not have perceived
the design of the Willard construction as an
obvious improvement.

D. Testimony as to Obviousness

28. Irving M. Fogel, offered by the de-
fendant as a witness on the obviousness of
the patent in suit, was in 1955 a civil engi-
neer in the construction business who was a
user of concrete. He did not state that he
had any familiarity with the art of design-
ing self-transit mixers, other than as a pur-
chaser and repairman of such vehicles, ei-
ther in 1955 or at any other time.

29. Robert W. Stieg, the defendant's
chief engineer in charge of special purpose
vehicles, was from 1940 until 1968 employed
by a company which manufactured and sold
self-transit mixer chassis and was involved
in the design of self-transit concrete mixer
chassis during those years. He stated thet
it would have been obvious in 1950 to him,
as a designer of such vehicles, to replace the
cylindrical drum in the dumper disclosed by
the Payne patent with a drum of fixed axis
of the type used in rear-discharge mixers at
that time. This testimony suggests that
the result of that replacement would be the
Willard construction. In his discussion of
the Payne patent, however, Stieg evidenced
an unfamiliarity with that construction as
disclosed in the patent. Furthermore, he
testified that he was unfamiliar with the
problems in the art of self-transit mixer
design in the 1950's which the Willard pat-
ent addressed and solved.

30. Richard B. Essex, a civil engineer
who was fom 1933 until 1977 a principal in
a company which used self-transit concrete
mixers, testified that in 1954 it would have

A - 26

1206 459 FEDERAL SUPPLEMENT

been obvious to him as a user of self-transit
mixers to replace the cylindrical mixing
drum on the “dumper” disclosed by the
Payne patent with a modern drum of fixed
axis, adding a drum extension and chute at
the discharging end of the drum, that is,
that the Willard construction would have
been obvious on the basis of the prior art.
Essex was in 1954 familiar with the types
of self-transit concrete mixers in use, and
he supervised at that time the assembly of
self-transit mixers (that is, mounting of
mixing drums onto chassis). However, he
was not engaged in the design of self-tran-
sit mixers then or at any other time (except
for consulting as to the design of vehicles,
which he did not explain), was not familiar
with their design and was unfamiliar with
the problems confronting that art in 1954.

31. Walter M. May, who has been an
engineer for the defendant since 1939 and is
currently executive vice-president of engi-
neering and product, testified that an ordi-
nary civil engineer who was not skilled in
the design of self-transit concrete mixers
could have made the invention disclosed iz.
the Willard patent on the basis of exam-
ining the prior art disclosures of the Payne
and Oury patents, and that a mechanic
might have been able to come up with the
Willard construction.

32. Robert W. Fay, a chemical engineer
who has been since 1964 a consultant and
executive involved in the engineering and
production of front-discharge self-transit
concrete mixers, testified that the Willard
construction would not have been obvious in
1954 to one skilled in the design of self-
transit concrete mixers. Fay was in 1954
not involved in or familiar with the design
of these vehicles, but his familiarity begin-
ning in 1964 with vehicles designed in the
mid-1950's and his participation in their de-
sign beginning at that time have made him
familiar with the state of the art in 1955.

E. Secondary Considerations

33. Since at least the early 1940's there
had been a need to develop a self-transit
concrete mixer which could deliver concrete
more efficiently, quickly and safely than
the vehicles which were in use at that time.
Throughout the 1940’s and early 1950's, the

A-27

advancements in the art of designing seif.
transit mixers were few and halting, e. g¢_
improvements to the mixing drums and
chutes for discharging concrete, and the
principal problems persevered. The front.
discharge self-transit mixer disclosed by the
Willard patent marked an extremely signif-
icant advance in solving these problems.
Immediately after its invention in 1955 the
Willard construction met with little com.
mercial success. The plaintiff R. W. Sims
made improvements on the construction dis-
closed in the Willard patent in the late
1950’s and early 1960's and he organized a
corporation which purchased a license under
the Willard patent and manufactured front-
discharge mixers. Eventually six compa-
nies, including every major mixer manufac.
turer except for the defendant and one
other, took licenses under the Willard pat-
ent to make, use and sell front-discharge
self-transit mixers. These front-discharge
mixers, incorporating improvements made
by licensees (including R. W. Sims) and
others (including the defendant), have en-
joyed considerable commercial success from
the mid-1960's until the present due to both
the advantages disclosed in the Willard con-
struction and those effected by the im-
provements. j

34. The application for the Willard pat-
ent was filed on July 18, 1955. On Novem-
ber 14, 1955, Evan S. Pritchard filed an
application for a patent relating to a front-
discharge self-transit concrete mixer which
disclosed a similar construction. In 1958
the plaintiff R. W. Sims began the process
which culminated in the design and produc-
tion of a prototype of a front-discharge
self-transit concrete mixer resembling the
Willard construction. Sims did not become
aware of the efforts of Willard or Pritchard
or of the constructions disclosed in these
patent applications until he had a patent
search conducted.

F. Combination

35. The component parts of the Willard
vehicle do not differ greatly from compo
nents of self-transit mixers which already
existed in the prior art. This construction

SIMS v. MACK TRUCKS, INC. 1207
Cite as 459 F.Supp. 1196 (1978)

employs a mixing drum already in common
use, a chute closely resembling that dis-
closed in the Merwin patent and a conven-
tional truck chassis and cab. The cylindri-
cal drum extension at the discharging end
of the mixing drum in the Willard patent
does not conform precisely to anything in
tke prior art, but it resembles closely the
drum extension at the discharging ond of
the Payne construction both in its general
shape (i e., of reduced diameter relative to
the adjacent drum section) and function (i
e., to project the discharge beyond the cab,
over it in the Willard construction and un-
der it in the Payne construction). The Wil-
lard patent thus represents a rearrange-
ment of elements known in the prior art.

86. Among the effects of this rearrange-
ment of known elements were the visibility
of the discharging operation to the driver of
the vehicle and more even weight distribu-
tion, producing more efficient, faster and
safer discharge while retaining the advan-
tages of modern mixing drum operation
and of high discharge of concrete afforded
by some rear-discharge mixers. These im-
provements were made possible by the rear-
rangement of the components disclosed in
the Willard patent rather than by the com-
ponents themselves.

Ill. INFRINGEMENT:

37. In 1973 the defendant engineered
and began to produce and sell HMM chassis
with half-cabs (i. e., cabs occupying only the
left half of the front of the vehicle), which
were specially designed to accommodate
concrete mixing drums which incline for-
wardly and discharge concrete above the
cab and out a chute in front of the cab, in
view of the driver.

88. In most instances from 1973 through
1975, the defendant sold HMM chassis only
to manufacturers of cement mixing drums
and to others, who would mount the drums
on the chassis. In some of these cases, the
defendant’s personnel would work with the
purchaser in order to insure that the chassis
and drum were properly “mated”, that is,
that the chassis which was purchased would
accommodate the drum properly. ’

89. In or before January 1977, the de-
fendant sold to purchasers 24 HMM chassis
with drums mounted on them and invoiced
the purchasers for the price of the entire
front-discharge mixer.

40. The defendant at no time manufac-
tured complete front-discharge mixer vehi-
cles consisting of chassis and mixing drums.

41. The defendant advertised to users of
self-transit concrete mixers HMM chassis in
brochures, in a promotional film and by
exhibition in a trade show. The defendant
did not limit its marketing effort to licen-
sees under the Willard patent. These pro-
motions mentioned that the defendant man-
ufactured only a chassis which was adapted
for use in a front-discharge concrete mixer.
The promotional film, exhibition and most
of the advertising depicted a complete
front-discharge self-transit concrete mixer,
however, and much of the defendant's ad-
vertising emphasized the advantages inher-
ent in front-discharge mixers rather than in
its HMM chassis alone.

42. The HMM chassis is adaptable to
other uses besides front-discharge mixers,
including rear-discharge concrete mixers,
dump trucks and trucks with block haulers
and cranes mounted on them. Of sixty-five

_ HMM chassis sold by the defendant as of

January 1977, sixty-two were ultimately
used for front-discharge mixers, one for a
rear-discharge mixer and two for special
conveyor bodies.

48. The front-discharge self-transit con-
crete mixer depicted by the defendant in its
advertisements and promotional film
(“HMM mixer”), i e., an HMM chassis and
cab with a forward discharging and for-
wardly inclined mixing bow] mounted upon
it, provides for the discharge of concrete in
view of the driver by positioning a mixing
drum in the shape of a cylinder and frus-
tum and a discharging chute in much the
same way as the Willard construction.

44. There are three main differences be-
tween the construction disclosed in the Wil-
lard patent and the HMM mixer. First, the
HMM mixer employs a half-cab, occupying
only the left side of the front of the chassis,
and the discharging end of the mixer is at

A- 26

1208 459 FEDERAL SUPPLEMENT

the front of the right side of the vehicle.
Consequently, the discharging end of the
mixing drum is to the right of and above
rather than directly above the cab as it is in
the Willard construction. However, the
functions of the relative positions of the
discharging end of the drum and the cab
are identical in-the HMM mixer and the
Willard construction: to provide high dis-
charge forward of the vehicle in view of the
driver. In addition, the discharging chute
in the HMM mixer is operated hydraulically
whereas the chute in the Willard construc-
tion is moved manually. Again, though, the
chutes serve the same function in both: the
placement of the discharging chute in the
HMM mixer is such that the driver can
position the means for concrete delivery to
a precise point. Third, the HMM mixer
does not have a cylindrical drum extension
at its discharging end but rather extends
the frustum portion of the drum to the
front of the chassis. This difference is of
little or no practical significance, however,
since the structure of the two drums is
quite similar and the functions of the elon-
gation of the frustum and the cylindrical
drum extension are identical: to bring the
discharging end of the forwardly inclined

fixed-axis mixing drum above and forward
of the cab.

45. The HMM mixer is a combination of
a truck chassis; a cab mounted on the front
of that chassis providing the driver with
forward visibility; bearings behind the cab
to support a mixing drum; a mixing drum
of fixed longitudinal axis upwardly inclined
toward the front with helical blades such
that it could discharge by rotating it; a
mixing drum composed of a cylindrical por-
tion for mixing and frustum-shaped section
forward of that extending in diminished
diameter over the cab; means for rotating
the drum located on the chassis; and a
removable chute for discharging the con-

crete supported by an arm attached to the
chassis.

46. The cab in the HMM mixer is locat-
ed at least partly under the discharge end
of the mixing drum in that it is of lower
elevation. The HMM chassis also has a
discharge chute supported by a supporting
arm mounted on the truck chassis upon

which the chute can be swung in and out of
the driver's vision.

47. In the HMM mixer most of the en-
gine is directly to the right of the driver's
cab, with a smaller part of the engine ex-
tending behind and to the right of the cab.

48. In the HMM mixer the driver's cab
is centered directly over the front axle.

IV. INTENTIONAL INFRINGEMENT:

49. The defendant was aware by 1963 of
the plaintiffs’ rights in the Willard patent
and of the plaintiff trustee R. W. Sims’
involvement in the production of front-dis-
charge mixers. In that year an officer of
the defendant visited R. W. Sims and re
ceived information concerning front-dis-
charge mixers. The defendant ultimately
decided not to enter into negotiations with
the plaintiffs for a license under the Wil-
lard patent because it concluded that there
was limited sales potential in this market.

50. In 1963 the defendant received from
its patent counsel an opinion that the Wil-
lard patent would be infringed by virtually
any front-discharge mixer with a cab
mounted on the front of the chassis. That
opinion concerned the scope of the Willard
patent only and not its validity..

51. During a survey conducted in 1963,
the defendant learned that a prominent
manufacturer of self-transit mixers had
concluded that the Willard patent was “ful-
ly bona fide” after a search by its patent
counsel.

52 In late 1972 the defendant was
asked by a customer and one of its distribu-
tors to produce for them a truck chassis
which could accommodate a front-discharge
concrete mixing drum. The defendant then
conducted a new market study on front-dis-
charge mixers and determined that it would
be advantageous to enter this market.

53. During the early part of 1973, while
it was engaged in the engineering and de-
velopment of the HMM chassis and cab, the
defendant was aware that production of
these units might create liability for in-
fringement by it of the Willard patent
Accordingly, the defendant’s new product

A-29

Pitesti wee ee

SIMS v. MACK TRUCKS, INC. 1209

committee decided at its January 1973
meeting to proceed with Phase I of the
engineering of the HMM chassis (involving
modification of an existing chassis) but de-
ferred a decision as to whether to embark
on Phase II (design of a complete HMM
chassis and cab which would be ready for
mounting of a mixer), apparently in light of
the patent problem.

54. A memorandum of the defendant
dated March 23, 1973, stated that the pat-
ent rights to front-discharge mixers had
been sold to a company which was experi-
encing financial difficulty.

55. At the defendant’s March 27, 1973
new product committee meeting, a commit-
tee member (the defendant’s director of
marketing product planning) stated that
the patent problem was no problem. At
that meeting the product committee decid-
ed to go ahead with Phase II of the HMM
program, involving engineering and release
of the chassis. No employee of defendant
had any reason at this time to believe that
the Willard patent was invalid.

56. At the March 27, 1973 new product
committee meeting, the officer of defend-
ant who stated that the patent problem was
no problem was advised to get an opinion
from the defendant’s patent counsel. On
April 18, 1973, the defendant’s patent coun-
sel stated that manufacture of the HMM
chassis and advertisement of its use in a
front-discharge mixer would induce in-
fringement of the Willard patent if the
total self-transit mixer construction would
80 infringe. In a letter dated July 5, 1973,
that counsel gave similar advice as to liabil-
ity for inducing infringement by advertis-
ing the HMM chassis’ use in a front-dis-
charge mixer and suggested that the de-
fendant authorize it to conduct a search
into the validity of the Willard patent.

57. Ina letter dated June 8, 1973, to one
of the defendant's distributors, defendant's
director of marketing product planning said
that in spite of the patent problem the
engineering of the HMM chassis was pro-
ceeding unimpeded and that the HMM pro-
gram was going and would continue to go
forward at full speed. .

58. Robert W. Stieg, an engineer for the
defendant, wrote in an August 7, 1973
memorandum that while the patent validity
search was being made the defendant was
continuing with Phase II of its engineering
for the HMM chassis in order to be prepar-
ed to show a front-discharge mixer at its
sales meeting in December 1973. Observ-
ing that the Willard patent would expire in
just over two years, Stieg stated that:

“I would assume the program would be of

value even if the patent was proved basic.

As I see it, the worst that could occur

would be a royalty payment for two years

by the party that mounted the front dis-
charge mixer on the chassis.”

This evaluation ignored the advice of patent
counsel that defendant might be liable for
inducing infringement even if it made and
sold only chassis if it advertised their use in
infringing mixers.

59. Defendant’s patent counsel rendered
an opinion on August 29, 1973, that the
Willard patent was either invalid or should
be limited in its coverage so as not to be
infringed by the front-discharge mixer em-
ploying a half-cab chassis as proposed by
the defendant. The defendant's patent
counsel’s letter of August 29, 1973, invited
the defendant to contact it with any ques-
tions or comments on its opinion of patent
invalidity. Walter M. May, the defendant's
vice-president of engineering and a member
of the new product committee who claimed
he relied on the opinion letter, undertook no
analysis of the opinion or further inquiry of
counsel. It does not appear that any other
employee of the defendant scrutinized that
opinion or the references contained therein
or contacted counsel.

60. The defendant knew at this time of
at least one opinion of counsel engaged by a
prominent mixer manufacturer that the
Willard patent was valid.

61. When it sought and received the
opinion letter from its patent counsel that
the Willard patent was invalid, the defend-
ant had already decided to engineer and sell
HMM chassis for use in front-discharge
self-transit mixers as soon as possible with-
out purchasing a license under the Willard

The Supreme Court in Graham stated that
the ultimate question of obviousness or non-
obviousness is a matter of law but added
that in § 103 cases three factual determina-
tions must underlie that ultimate resolu-
tion: the scope and content of the prior art;
the differences between that prior art and
the claims of the patent in suit; and the
level of ordinary skill in the pertinent art.
It added that secondary considerations such
as the commercial success of the patented
construction and its fulfillment of long felt
and unresolved needs might be relevant to
the obviousness question. 383 U.S. at 17-
18, 86 S.Ct. at 693-694.

There is little room for disagreement as
to the scope of the prior art relevant to the
Willard patent or the differences between it
and the Willard patent. The only signifi-
cant contention advanced by the defendant
as to these factual matters with which I
disagree is the suggestion that the Payne
patent embodies the primary advantage of
the patent in suit: the discharge of con-
crete in th® view of the driver from the
truck to the point where it is to be applied,
with the greater efficiency and speed stem-
ming from that advantage. It is not clear
to what extent the driver of a Payne vehi-
cle would be able to observe from the cab
the discharge of ‘concrete and to vary the
point of discharge without assistance and
without leaving the cab. The description of
the Payne patent makes it clear, however,
that it does not contemplate the use of the
construction disclosed in it in that manner.
Rather, the Payne construction is to be used
in combination with a portable concrete dis-
tributor. The Payne mixer would be able
to be driven to the loading point of that
portable distributor without the driver hav-
ing to leave the cab, but the Payne patent

contemplates that the concrete be applied
to the work area not from the truck but
from the portable distributor, which would
be transported and operated by other work-
men. Hence the advantage disclosed in the
Willard patent of a one-person discharging
operation was not anticipated by this prior
art. This difference between the Payne

"You have never been now, you.are not

now, and never have been, in the design
business. You are not an expert in the
design of front, of front discharge transit
mixers?"

"That is correct." (647A)

"I call your attention to the fact that in
your qualifications there is a section on
design, and throughout the application there
refers to the field of transit mixer trucks
making concrete, serving as a consultant,
and you put behind the reference to design,
zero time. That is correct, is it not,
that is your handwriting?" (1282A-1)

"That is correct." (648A)

documents testified to by any engineer
in the form of any documents that have

to do that?"

"That is correct."

"Tt is not the result of any search which
you did, is it?"

"No,Sir." (652A)

"Did you ever compare any opinion that
you might offer to the court today with
an opinion of an expert employed either
by Rexnord or by Mack Trucks?"

"No, Sir." (653A)

Considering the foregoing, it is apparent that Essex had

never been a designer of anything (much less concrete mixer trucks).

Essex had not even a perception of the problem of the art at the

time of the invention (744A), so how could he testify as to a solu-

tion? He failed to understand the advantages of a front discharge

mixer, unlike Mr. May, the Mack Vice President, who followed Richard

Essex to the stand (720A). Essex had never undertaken any studies

in connection with the lawsuit, confined himself to elements of

prior art selected by the defendant's counsel, had never even consulted
the technical tests and studies that Mack had which were contrary

- to his testimony, and had never even considered the interpretation

of the oxlox art given by the Patent Office (673A). Essex never

tested or, indeed, even examined the test results of Mack's front
discharge mixer, or even asked or took the trouble to ask for any

of their test results or examined their product (657A).

As a matter of fact, Mack's witness, Essex, on cross-examination,

actually testified favorably about the revolutionary character

of the Willard invention. The record speaks clearly:

"How long and how persistent were the

patents? Of how long duration were they?
Were they of some long-standing duration?
If you know."

"The fact that the truck mixer dumped out
of the rear the problem had been there for
many, many years."

"Do you believe that the invention is
revolutionary?"

"It is different."
"It is revolutionarily different?"
"It is 180 degrees different."

"That's about as far away as you can get,
the North and South Pole, isn't it?"

"That's right."

"So, viewed from the prior art, he not only
broke with the prior art, he revolutionized
the art, didn't he?"

"In that he enabled the truck to forward
discharge, he revolutionized the art."
(666A, 667A)

of the District Court that the obviousness question posed to Mr.
