MEMORANDUM

ROBERT F. KELLY, Sr. J. MAY 15, 2007

Presently before this Court is Defendant Woodstream Corporation’s (“Woodstream”)

Renewed Motion for Judgment as a Matter of Law and in the Alternative, for Remittitur and for a

New Trial. For the following reasons, this Motion is granted in part and denied in part.

I. BACKGROUND

Plaintiff Agrizap, Inc. (“Agrizap”) brought suit against Woodstream for patent

infringement of its U.S. Patent No. 5,949,636 entitled “portable pest electrocution device with

resistive switch trigger” (“636 patent” or “Rat Zapper”). Agrizap also alleged related state law

claims. The only state law claim to survive summary judgment was its fraudulent

misrepresentation claim regarding Woodstream sending the Rat Zapper overseas for cost

evaluation. 

A jury trial on this matter commenced on February 20, 2007 and concluded on March 7,

2007. The jury returned a verdict in Agrizap’s favor on both the patent infringement claim and

the fraudulent misrepresentation claim. Specifically, with respect to the infringement claim, the

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 1 of 19
2

jury found that Woodstream did not infringe Claims 1, 2, 3, 5, or 10 of the 636 patent, but did

infringe Claim 16 of the 636 patent. The jury found that Woodstream’s infringement was not

willful. Moreover, the jury found that Woodstream did not prove, by clear and convincing

evidence, any of its affirmative defenses to infringement. 

With respect to damages, the jury awarded $1,425,000 for the infringement of claim 16. 

This amount consists of $900,000 for Agrizap’s lost profits and $525,000 for its reasonable

royalty claim. The jury awarded $1,275,000 in damages for the fraudulent misrepresentation

claim. Thus, the jury awarded Agrizap damages totaling $2,700,000.

Following the jury verdict, Woodstream filed this present Motion renewing its motion for

judgment as a matter of law that it made at the close of evidence. Woodstream is seeking

judgment as a matter of law on the fraudulent misrepresentation claim and on the infringement of

Claim 16 of the 636 patent. Woodstream is also seeking judgment as a matter of law on its

affirmative defenses of patent invalidity (for obviousness, incorrect inventorship, lack of written

description/ new matter, and lack of enablement) and of inequitable conduct (for failure to

disclose the prior public use of the Gopher Zapper to the Patent and Trademark Office and for

removing Bruno Rist as a named inventor). In the alternative, Woodstream moves for remittitur

of the fraudulent misrepresentation damages to $55,000 and for a new trial.

II. LEGAL STANDARDS

A. Renewed Motion for Judgment as a Matter of Law

Under Rule 50(b) of the Federal Rules of Civil Procedure, a party may renew its motion

for judgment as a matter of law after the jury’s verdict. Fed. R. Civ. P. 50(b). Rule 50(b)

provides, in relevant part, that “[i]f the court does not grant a motion for judgment as a matter of

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 2 of 19
3

law made under subdivision (a), the court is considered to have submitted the action to the jury

subject to the court’s later deciding the legal questions raised by the motion.” Id. “The movant

may renew its request for judgment as a matter of law . . . and may alternatively request a new

trial . . . under Rule 59.” Id. In ruling on a renewed motion when a verdict was returned by the

jury, a court may (A) allow the judgment to stand; (B) order a new trial; or (C) direct entry of

judgment as a matter of law. Id.

A judgment as a matter of law may be granted only if “there is no legally sufficient

evidentiary basis for a reasonable jury” to find for the nonmoving party. Fed. R. Civ. P. 50(a). 

Such a motion will only be granted if, viewing the evidence in the light most favorable to the

nonmoving party and giving the nonmoving party the advantage of every fair and reasonable

inference, there is insufficient evidence from which a jury could reasonably find liability. 

Lightning Lube, Inc. v. Witco Corp., 4 F.3d 1153, 1166 (3d Cir. 1993). The court may not weigh

the evidence, determine the credibility of witnesses, or substitute its version of the facts for the

jury’s version. Id. “Although judgment as a matter of law should be granted sparingly, a scintilla

of evidence is not enough to sustain a verdict of liability.” Id. The question for the court is not

whether there is literally no evidence supporting the nonmoving party but whether there is

evidence upon which the jury could properly find a verdict for that party. Id. 

B. Motion for Remittitur

In general, remittitur is only granted if the verdict awarded is “so grossly excessive as to

shock the judicial conscience.” Johnston v. Sch. Dist. Of Phila., No. 04-4948, 2006 WL 999966,

*6 (E.D. Pa. Apr. 12, 2006) (quoting Keenan v. City of Phila., 983 F.2d 459, 469 (3d Cir. 1992)). 

If a trial judge, in his or her discretion, finds that the jury’s decision is clearly unsupported and/

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 3 of 19
4

or excessive in light of the evidence, and where no clear judicial error or pernicious influence can

be identified, the judge shall order the plaintiff to remit a portion of the verdict in excess of the

maximum amount supportable by the evidence or, if plaintiff refuses remittitur, the judge shall

submit the issue of damages to a new trial. Parkway Garage, Inc. v. City of Phila., No. 90-7752,

1994 WL 412430, *6 (E.D. Pa. Aug. 3, 1994). This Court has broad discretion in whether to

grant remittitur because a district court is in the best position to evaluate the evidence presented

and determine whether or not the jury has come to a rationally based conclusion. Id.; Spence v.

Bd. of Educ., 806 F.2d 1198, 1201 (3d Cir. 1986); Johnston, 2006 WL 999966 at *6. 

C. Motion for a New Trial

As stated above, a party making a renewed motion for judgment as a matter of law, may

move, in the alternative, for a new trial pursuant to Federal Rule of Civil Procedure 59. A new

trial may be granted after a jury verdict “for any of the reasons for which new trials have

heretofore been granted in actions at law in the courts of the United States.” Fed. R. Civ. P. 59. 

“A new trial is appropriate only when the verdict is contrary to the great weight of the evidence

of errors at trial produce a result inconsistent with substantial justice.” Sandrow v. United States,

832 F. Supp. 918, 918 (E.D. Pa. 1993). 

III. DISCUSSION

A. Renewed Motion for Judgment as a Matter of Law

1. Infringement of Claim 16

Woodstream contends that it is entitled to judgment as a matter of law because its

microprocessor-based Electronic Mouse and Rat Traps (“EMT’s” and “ERT’s”) cannot literally

infringe Claim 16 of Agrizap’s 636 patent. According to Woodstream, Claim 16 is an apparatus

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 4 of 19
5

claim that recites specific mechanical and electronic components of the 636 patent and its EMT’s

and ERT’s do not contain these components but rather are microprocessor-based systems. 

Woodstream cites Overhead Door Corp. v. The Chamberlain Group, Inc., 194 F.3d 1261 (Fed.

Cir. 1999), as support for the proposition that a microprocessor cannot, as a matter of law,

literally infringe specifically claimed mechanical and electronic structures. Infringement under

such circumstances can only be supported by the doctrine of equivalents, a theory which was not

applicable to this case. Agrizap counters that Overhead Door does not stand for so sweeping an

assertion that microprocessors cannot literally infringe a hard-wired circuit structure. 

Additionally, Agrizap argues that Claim 16 does not even require hard-wired circuitry and it

believes that the testimony of its expert, Dr. Feinberg, was legally sufficient for the jury to

reasonably find in Agrizap’s favor.

As Claim 16 is an apparatus claim, this Court construed it to consist of specific electronic

components, such as a high voltage and current generator, a resistive switch, a trigger circuit, and

a timing module. See Agrizap, Inc. v. Woodstream Corp., 431 F. Supp. 2d 518, 531 (E.D. Pa.

2006). Subparagraphs (b)(i), (b)(iii), and b(iv) of Claim 16 were at issue in this case. Below is

the text of these subparagraphs of Claim 16 followed by this Court’s claim construction of them. 

See id. at 531-532.

Subparagraph (b)(1) of Claim 16 states:

b) an electronic portion comprising:

i) a resistive switch coupled between said high voltage electrode and said

reference electrode, said resistive switch further comprising a trigger circuit

having a trigger output and an arm/ disarm input.

This claim was construed as: a switch that is physically connected across the electrodes. The

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 5 of 19
6

switch includes a distinct trigger circuit with a trigger output and an arm/ disarm input.

Subparagraph (b)(iii) of Claim 16 states:

a timing module having an input coupled to said trigger output of said resistive

switch, a control output coupled to said generator control input and an arm/

disarm output coupled to said arm/ disarm input of said resistive switch.

This claim was construed as: a specific distinct timing module having an input and two outputs. 

The input is connected to the trigger output of the resistive switch. A control output is connected

to the high voltage generator control input. An arm/ disarm output is connected to the arm/

disarm input of the resistive switch. 

Lastly, the last clause of subparagraph (b)(iv) states:

said timing module disarms said trigger circuit of said resistive switch upon said

activation of said timer module until said timer module is reset.

This clause was construed as: the timing module has an output that is coupled to the trigger

circuit of the resistive switch to disarm the trigger circuit until a power on reset signal re-enables

or re-sets the timing module. 

To address Woodstream’s arguments about Overhead Door, this Court will provide a

brief overview of its relevant parts. Overhead Door concerned two parties, the Chamberlain

Group, Inc. and Overhead Door Corp. that both manufacture remote control garage door opener

systems. 194 F.3d at 1264. Overhead Door sought a declaratory judgment that its Intellicode

garage door opener system did not infringe the 364 patent, Chamberlain’s garage door opener

system. Id. at 1266. Remote control garage door systems usually include a portable transmitter

and a stationary garage door opening motor with a processing unit and receiver. Id. at 1264. The

transmitter sends a signal to the receiver to open or close the garage door. Id. These systems

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 6 of 19
7

utilize coded signals to prevent signals from foreign transmitters from opening the door. Id. 

Thus, a unique code links each transmitter to its own system. Id. The 364 patent enabled a

garage door opener to learn the identities of and respond to multiple transmitters with different

codes. Id. Overhead Door’s Intellicode system also can learn to identify multiple transmitters. 

Id. at 1266. 

Both inventions store transmitter codes in selected memory locations during the learning

process. Id. While the 364 patent uses a manual, mechanical memory switch to perform this

function, the Intellicode system does not. Id. Instead, the Intellicode system uses “software that

determines the memory location for each new code.” Id. “The Intellicode’s microprocessor,

under control of the software, identifies unused locations in memory and automatically stores a

new code in an unused and available location.” Id. 

The claim language of the 364 patent in question is “a memory selection switch

connected to said microprocessor.” Id. at 1265. The district court construed this claim:

to mean “a switch separate from the microprocessor which is user operated to

select different positions of the switch.” The claim uses the term “switch,” a word

connoting a mechanical device with different settings, such as “on” and “off.” 

Claim 1 further defines the memory selection switch as “connected to” the

microprocessor, “setable in” a first position, and “set in” a second position. This

claim language is more consistent with a mechanical switch attached to the

microprocessor, rather than software programmed into the microprocessor.

Id. at 1267. The Federal Circuit interpreted “memory selection switch” to mean “a mechanical

switch with different positions, each position corresponding to a different location in memory,

thus enabling the garage door operator to store codes in different memory locations.” Id. at 1269. 

Thus, the Federal Circuit affirmed the district court’s interpretation of “memory selection

switch.” Id.

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 7 of 19
8

Using this interpretation, the Federal Circuit affirmed the district court’s finding of no

literal infringement. The Federal Circuit held that the claim language in the 364 patent covers a

mechanical memory selection switch and the Intellicode system, in contrast, selects memory

locations with a software program, not with a mechanical switch. Id. Thus, the “memory

selection switch” is literally absent from the Intellicode system. Id. 

Agrizap views Overhead Door as simply stating that there was no literal infringement

because the memory selection switch connected to the microprocessor is absent from the

Intellicode system, which only has a microprocessor and no switch. Thus, Agrizap understands

this case as saying nothing about whether microprocessors can literally infringe hardwired

structures. Moreover, Overhead Door is inapplicable to this present case because neither Claim

16 nor its claim construction require an element connected to a microprocessor.

Overhead Door, however, is not simply about a lack of literal infringement because the

accused device is missing a switch connected to the microprocessor. Rather, the opinion’s focus

was on the fact that a microprocessor/ software implementation of a memory selection function

cannot literally infringe a mechanical switch implementation of that same function. The 364

patent has a mechanical “memory selection switch” that selects memory locations. The

Intellicode system has a software program to select memory locations. Both inventions have a

common functionality: selecting memory locations. However, each invention uses a different

structure to achieve the function: a mechanical switch in the 364 patent and a microprocessor in

the Intellicode system. The Federal Circuit viewed the switch and the microprocessor as

different structures and found no literal infringement. The court did, however, find that the

doctrine of equivalents could possibly apply. Id. at 1269-71. So at best, software

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 8 of 19
Two commentators have actually found it troubling that cases, such as Overhead Door suggest that 1

software implementations of certain ideas are equivalent to older mechanical implementations. Burk & Lemley, 17

Berkeley Tech. L. J. at 1172. If these commentators find equivalency troubling, this Court can logically infer that

they would not think literal infringement is a possibility.

9

implementation of certain mechanical implementations can only be infringed under the doctrine

of equivalents. See id.; Dan L. Burk & Mark A. Lemley, Is Patent Law Technology-Specific?

1

17 Berkeley Tech. L. J. 1155, 1172 (2002). Accordingly, in this present case, the

microprocessor-based implementation of the functions of an electronic rat trap cannot literally

infringe specific, physical electronic components, such as a resistive switch, trigger circuit, and

timing module, that implements those same functions.

Moreover, the fact that the code instructions and the microprocessor of the EMT’s and

ERT’s carry out the same functions as Claim 16 does not establish literal infringement. Claim 16

is solely an apparatus claim, so it has nothing to do with functionality. “[A]pparatus claims

cover what a device is, not what a device does.” Hewlett-Packard Co. V. Bausch & Lomb Inc.,

909 F.2d 1464, 1468 (Fed. Cir. 1990). Therefore, any arguments about the code and the

microprocessor carrying out the same function as Claim 16 are irrelevant. 

This Court must also address Agrizap’s argument that Dr. Feinberg provided legally

sufficient evidence to establish literal infringement of Claim 16. Dr. Feinberg “explained that

although the circuits in the Woodstream traps are governed by a microprocessor running code

instructions, physical components are still required to carry out the code instructions, and are thus

necessarily present.” (Agrizap’s Resp. to Woodstream’s Renewed JMOL Mot., 7-8). “He

further explained that those physical components are located inside the microprocessor, and must

be present to carry out the specified code instructions. From this, the jury could - and did -

reasonably conclude that the specified physical circuits exist in the microprocessor.” (Id. at 8.) 

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 9 of 19
10

The specific, physical electronic and mechanical components described in Claim 16 are not

present within the microprocessor. Just because two devices do the same function does not mean

that they must have the same structure. While Dr. Feinberg gave factual testimony that the

components of Claim 16 are actually located within the microprocessor, his contentions are

untenable in light of the Federal Circuit’s holding in Overhead Door. As explained above, that

case shows that the structure of a microprocessor cannot literally infringe mechanical structures. 

While the Federal Circuit did not even address whether the components inside the

microprocessor literally infringed the mechanical memory selection switch, it did not need to

because the fact that a microprocessor itself is different from the switch in question was enough

to find no literal infringement.

In conclusion, the structural limitations of Claim 16, i.e., the resistive switch, trigger

circuit, and timing module, and the connections between them, are not literally present in

Woodstream’s EMT and ERT. “Literal infringement of a claim requires that every limitation

recited in the claim appear in the accused device, i.e., that the properly construed claim reads on

the accused device exactly.” Amhil Enterprises Ltd. v. Wawa, Inc., 81 F.3d 1554, 1562 (Fed.

Cir. 1996). “To infringe an apparatus claim, the device must meet all of the structural

limitations.” Cross Medical Products, Inc. v. Medtronic Sofamor Danek, Inc., 424 F.3d 1293,

1311-12 (Fed. Cir. 2005). While even though Dr. Feinberg provided evidence at trial that the

components recited in Claim 16 were literally present within the ERT and EMT microprocessor,

his testimony is in contradiction of the law. A microprocessor that does the same thing as

distinct physical, electronic components is not literally infringing. They may do the same

function, but they are not the same device. And when looking at infringement of an apparatus

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 10 of 19
11

claim the issue is on what the device is not was it does. Therefore, Woodstream’s EMT and ERT

do not literally infringe Claim 16 of the 636 patent and Woodstream is entitled to judgment as a

matter of law. 

2. Woodstream’s Affirmative Defenses

Woodstream also argues that it should be granted judgment as a matter of law on all of its

affirmative defenses to patent infringement. Prior to trial, Woodstream moved for summary

judgment based on those defenses. This Court denied that motion. See Agrizap, Inc. v.

Woodstream Corp., 431 F. Supp. 2d 518, 532-544 (E.D. Pa. 2006).

The standard for summary judgment mirrors the standard for judgment as a matter of law

under Federal Rule of Civil Procedure 50(a), “which is that the trial judge must direct a verdict if,

under the governing law, there can be but one reasonable conclusion as to the verdict.” Anderson

v. Liberty Lobby, Inc., 477 U.S. 242, 250 (1986). The primary difference between the two

motions is procedural. Id. at 251. Summary judgment motions are usually made before trial and

decided on documentary evidence and judgment as a matter of law motions are made at trial and

decided on evidence admitted at trial. Id. Nevertheless, “the inquiry under each is the same:

whether the evidence presents a sufficient disagreement to require submission to a jury or

whether it is so one-sided that one party must prevail as a matter of law.” Id. 

At trial, Agrizap and Woodstream presented similar arguments and similar evidence for

these defenses as they did at the summary judgment stage. This means that at both stages of the

case, a sufficient disagreement between the parties existed as to prevent this Court from making a

judgment as a matter of law. The jury thereby was not unreasonable and had a sufficient

evidentiary basis for its decision in favor of Agrizap on these defenses. Because of the

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 11 of 19
12

similarities between this motion and the summary judgment motion, this Court’s reasoning for

denying summary judgment is applicable here and should be incorporated by reference. See

Agrizap, 431 F. Supp. 2d at 532-544. Therefore, Woodstream’s renewed motion for judgment as

a matter of law on the defenses to patent infringement is denied.

3. Fraudulent Misrepresentation

Woodstream contends that it should be granted JMOL on Agrizap’s Fraudulent

Misrepresentation Claim, because there was insufficient evidence produced at trial to permit a

reasonable jury to conclude that Agrizap had met its burden of proof with respect to the elements

of fraudulent misrepresentation. Those elements are: 

(1) A representation:

(2) Which is material to the transaction at hand;

(3) Made falsely, with knowledge of its falsity or recklessness as to whether it 

is true or false; 

(4) With the intent of misleading another into relying on it;

(5) Justifiable reliance on the misrepresentation; and

(6) The resulting injury was proximately caused by the reliance.

Gibbs v. Ernst, 647 A.2d 882, 889 (Pa. 1994).

(1) A Representation

At trial Agrizap produced evidence that on August 15, 2000, Robert Noe sent an

e-mail to Andy Woolworth, Executive Vice-President of Woodstream, indicating that Noe was

aware that Woodstream had sent Rat Zappers to China. Noe stated in part, “We want your

assurance that this manufacturer or any other contact of yours will not, directly or indirectly,

attempt the cloning of any of our product line.” (Tr. 2/20/07, pp. 86:1-87:11; PX 39.)

On August 25, 2000, Andy Woolworth responded to this request in an e-mail

which stated “Bob - Please reference our point 5 of the confidentiality agreement to cover your

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 12 of 19
13

concern below. We asked a source that does millions of dollars of work for Woodstream in an

ISO 9000 facility to quote on the product.” (Tr. 2/20/07, p. 88:16-91:9, 92:3-6; PX 40.)

(2) The Represention would have been material to the transaction.

There is evidence at the trial that Woodstream was aware that if Agrizap found

out about the competing product it was developing it would refuse to deal with Woodstream. 

(Tr. 2/28/07, pp. 183:14: Tr. 3/1/07, pp. 59:16-64: 23; PX 23, PX 165.)

There was evidence at trial that indicated that when Agrizap found out about

Woodsteam’s competing product, it did in fact refuse to sell anymore Rat Zappers to

Woodstream. (Tr. 2/20/07, p. 116:13-20.) Mr. Noe testified that he would have considered the

fact that Woodstream was considering developing its own competing traps to be important. (Tr.

2/20/07, pp. 114:9-116:23.) The jury could have reasonably concluded from the evidence that

Mr. Woolworth did not respond honestly to Mr. Noe’s request for assurance, and that if he had,

Mr. Noe would never have agreed to allow Woodstream to sell Rat Zappers under its Victor

label. Under these circumstances the jury could find that the representation was material.

(3) Representation made falsely, with knowledge or recklessness

 to whether it was true or false. 

From the exchange of e-mails in PX 39 and PX 40, a jury could conclude that Mr.

Woolworth was displaying a reluctance to respond directly to Mr. Noe’s original question: “we

want your assurance that this manufacturer or any other contact of yours will not directly or

indirectly attempt the cloning of any of our product line.” (PX 39, e-mail of 8/15/00.)

The e-mail from Mr. Woolworth to Mr. Noe of 8/24/00, (PX 40), ignores the

question. This prompts another e-mail from Mr. Noe to Mr. Woolworth dated 8/26/00 (New

Zealand time) in which Mr. Noe finds it necessary repeat his request. 

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 13 of 19
14

Finally, in an e-mail dated 8/25/00 (U.S. time) Woolworth sent the reply that

seems to have satisfied Mr. Noe’s concern. (PX 40) 

There was also evidence presented to the jury that approximately 5 days after this

exchange of e-mails, Woodstream instructed its Chinese supplier that it would make the product

itself. (Tr. 2/26/07, pp. 116:13-119:4; PX 37; PX 40, PX 41.) The reluctance to answer Mr.

Noe’s original question and the speed with which Woodstream proceeded with the decision to

make the product itself would justify a jury’s conclusion that Mr. Woolworth knew that the

statement contained in his 8/25/00 e-mail was not correct.

(4) With the intent of misleading another into relying on it.

As soon as Agrizap discovered that Woodstream had introduced a competitive

electronic mousetrap Agrizap terminated the relationship with Woodstream. (Tr. 2/20/07, pp.

114:9-116:23.) The jury also heard testimony from Woodstream employee Steve Polisoto

indicating that Woodstream knew Agrizap would discontinue sales to Woodstream once Agrizap

found out about Woodstream’s competing product. (PX 20; PX 26; PX 164; Tr. 3/1/07, pp.

60:2-64:22.) There was also evidence that Woodstream actively sought to prevent Agrizap from

finding out that it was considering developing a competing trap. (DX 130; PX 44; Tr. 2/28/07,

pp. 37:9-40:12.)

From the foregoing the jury could certainly conclude that Woodstream intended

Agrizap to rely on Mr. Woolworth’s statement to Mr. Noe as to why the Rat Zapper was sent to

China.

(5) Justifiable reliance on the misrepresentation 

Agrizap presented evidence from which the jury could find that Agrizap

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 14 of 19
15

reasonably relied upon Woodstream’s misrepresentations. Woodstream frequently referred to

Agrizap as a “partner”, causing Agrizap to believe that the two companies were working together

and that Mr. Woolworth’s previous representations to Mr. Noe were truthful. (Tr. 2/20/07, p.

95:2-7; Tr. 2/22/07, pp. 120:8-22, 128:20-130:13; PX 38; PX 12; PX 13; PX 19; PX 52; PX

153.) Agrizap even provided training to Woodstream employees regarding the Rat Zapper. (Tr.

2/22/07, pp. 142:4-144:16.)

(6) The resulting injury was proximately caused by the reliance.

Woodstream contends that Agrizap failed to support the award of damages with

sufficient evidence. 

[U]nder Pennsylvania law, in an action based on fraud, the measure of

damages is “actual loss” and not the benefit, or value, of that bargain. 

The victim is entitled to all pecuniary losses which result as a consequence

of his reliance on the truth of the representations.

The determination of damages is a factual question to be decided by

the fact-finder. This duty of assessing damages is within the province

of the fact-finder and should not be interfered with unless it clearly

appears that the amount awarded resulted from partiality, caprice,

prejudice, corruption or some other improper influence. The fact-finder

must assess the worth of the testimony, by weighing the evidence and 

determining its credibility, and by accepting or rejecting the 

estimates of the damages given by the witnesses. In reviewing 

the award of damages, the appellate courts should give deference

to the decisions of the trier of fact who is usually in a superior

position to appraise and weigh the evidence.

The standard in Pennsylvania civil cases for determining future

damages is that the plaintiff bears the burden of proof by a 

“preponderance of the evidence.” Under this criterion, the 

plaintiff is required to furnish only a reasonable quantity of 

information from which the fact-finder may fairly estimate the

amount of damages. Though justice and public policy require

that the wrongdoer bear the risk of uncertainty which his own 

wrong has created and which prevents the precise computation

of damages, the fact-finder still may not render a verdict based 

Case 2:04-cv-03925-RK Document 240 Filed 05/15/07 Page 15 of 19
16

on speculation or guesswork. Yet, the fact-finder may make a

just and reasonable estimate of the damage based on relevant

data, and in such circumstances may act on probable and 

inferential, as well as upon direct and positive proof. Thus,

the law does not demand that the estimation of damages be

completely free of all elements of speculation. While the

trier of fact may not use sheer conjecture as a basis for

arriving at a verdict, it may use a measure of speculation

in aiming at a verdict or an award of damages, and an 

even greater degree of flexibility is granted in regard to

testimony concerning prospective or future damages, which

are at best, not always easy or certain of ascertainment

and are to a large extent based on probabilities and

uncertainties. So then, mere uncertainty as to the amount

of damages will not bar recovery where it is clear that the

damages were the certain result of the defendant’s conduct.

Generally, under Pennsylvania law, damages need not be

proved with mathematical certainty, but only with reasonable

certainty, and evidence of damages may consist of 

probabilities and inferences. Although the law does not

command mathematical precision from evidence in finding

damages, sufficient facts must be introduced so that the court

can arrive at an intelligent estimate without conjecture. 

Where the amount of damage can be fairly estimated from 

the evidence, the recovery will be sustained even though such

amount cannot be determined with entire accuracy. It is only

required that the proof afford a reasonable basis from which 

the fact-finder can calculate the plaintiff’s loss.

Delahanty, 464 A.2d at 1257-1258 (internal citations omitted)

(emphasis supplied).

The jury awarded damages of $1.275 million dollars for fraudulent

misrepresentation. At trial Agrizap claimed that had it known the truth, [i.e. had it known that

Woodstream sent the Rat Zapper to China for a reason other than costing] it would not have

continued the purchase order arrangement with Woodstream. In other words Agrizap would

have continued to market and sell Rat Zappers itself from September 2000 onward, just as it had

done previously. Agrizap’s evidence as to damages, revealed at least from Agrizap’s point of

view, that as a result of the fraud Agrizap continued to sell Rat Zappers to Woodstream. Agrizap

provided evidence from which the jury could conclude that it would not have continued to give a

preferred price to Woodstream, and would not have provided Woodstream with the means to

enter the electronic rat and mouse trap market in the year 2000, if it knew at the very time it did

so, Woodstream had sent its product to China for the purpose of “designing around” it or

“cloning” it. 

Agrizap would not have given Woodstream exclusive access to certain large

retailers in the market, i.e. Home Depot, Ace Hardware, thus, allowing Woodstream to establish

itself in those markets years earlier than it could otherwise have. (Tr. 2/22/07, pp. 139:14-141:5;

PX 47). To this Woodstream argues that Home Depot and Ace Hardware would not have bought

Rat Zappers from a small operation such as Agrizap anyway. But, that argument is speculation

and the jury did not accept it. What is not speculation is that once Agrizap allowed a larger

corporation such as Woodstream to develop those markets it would have no chance to win them

back, competing against an almost identical product. Certainly the jury had the right to consider

how that would impact future loses to Agrizap. 

Not only did Agrizap defer to Woodstream in certain markets, Scott Heaton an

Agrizap employee at the time, testified about training Woodstream sales people to sell Rat

Zappers. (Tr. 2/22/07 141:4-8).

Not only were there lost sales from the years 2000 to 2003, there were lost future

sales from markets Agrizap will probably never win back competing against such a well

established company as Woodstream.

Agrizap presented evidence relating to the total market share of the electronic

mousetrap industry compared to other non-electronic traps. (PX 14; Tr. 2/27/07, pp. 201:24-

204:11.) Agrizap’s evidence showed that the total market share of the industry is $20 million per

year. (PX 14 @ W903). Woodstream’s goal was to gain a first-in market share penetration of

50% of this total market share in five years. (Id.) 

Based upon this evidence the jury returned a verdict of $1.27 million. Given the

financial data that was presented to the jury and drawing inferences in favor of Agrizap, the jury

was not unreasonable in awarding $1.275 million dollars for past and future damages to Agrizap

as a result of Woodstream’s fraudulent misrepresentations concerning its intentions with respect

to its sending the Rat Zappers to China. 

B. Motion for Remittitur

Defendants’ Motion for Remittitur is denied for the same reasons discussed in our denial

of Defendants’ JMOL motion as to fraudulent misrepresentation.

C. Motion for a New Trial

In the alternative, Woodstream requests that this Court grant a new trial on all the claims

and defenses because “the jury’s verdict ‘is contrary to the great weight of the evidence or errors

at trial produce a result inconsistent with substantial justice.’” (Woodstream’s Renewed JMOL

Mot., 3 (citing Mullins v. City of Phila., No. 06-2186, 2007 U.S. Dist. LEXIS 16114, *4 (E.D.

Pa., Mar. 7, 2007))). Woodstream, however, has not provided any specifics as to why a new trial

should be granted. Woodstream has neither explained why the jury’s verdict was contrary to the

weight of the evidence nor has indicated any trial errors that resulted in substantial injustice. 

Therefore, Woodstream’s Motion for a New Trial is denied.

We therefore enter the following Order.
