LALLEMAND SPECIALTIES, INC. &
MASCOMA LLC,
Defendants and Counterclaimants.
This patent case is set for a jury trial commencing May 7, 2018, to resolve plaintiffs’
claim of patent infringement. In advance of the final pretrial conference scheduled for
April 25, the court issues the following opinion and order on the parties’ respective motions
in limine.1
OPINION
I. DSM’s Motions in Limine (dkt. #185)
A. MIL No. 1: Exclude Evidence and Argument that Reduced Glycerol
Production in the Accused Products Is Not Caused by the Deletion of the
GPD2 Gene.
DSM’s first motion seeks to prevent Lallemand from arguing or presenting evidence
that the Accused Products were “sufficiently altered to make any reduction in glycerol
Consistent with the court’s summary judgment decision, plaintiffs will be referred to collectively
as “DSM,” while defendants will be referred to collectively as “Lallemand.” Also before the court
is Lallemand’s motion for leave to file replies (dkt. #225), with the proposed briefs attached as
exhibits. While the court has reviewed these proposed briefs and has cited them occasionally in
this opinion and therefore will grant the motion, the court notes that this practice is generally
discouraged, especially when replies are simply used to restate arguments already made.

production unrelated to the elimination of the gpd2 gene as compared to the corresponding
wild-type cells,” as such an argument “is contradicted by the sworn testimony of
Lallemand’s own Rule 30(b)(6) witness, is not supported by any facts, and would confuse
and mislead the jury.” (Dkt. #185 at 1.) Specifically, DSM asserts that Lallemand
conducted batch testing to compare glycerol production between the Accused Products and
corresponding wild-type cells “conclusively demonstrat[ing] that the Accused Products . . .
exhibit a reduced rate of glycerol production.” (Id. at 1-2.) Further, DSM criticizes Dr.
Winge’s statement at the expert colloquy that the Accused Products’ reduction in glycerol
production was unrelated to the deletion of the GPD2 gene as unsupported and
contradicted by his other testimony, as well as by testimony of Lallemand’s 30(b)(6)
witness, Dr. Kevin Wenger, that the “knockout of that gene has some impact, some effect
of glycerol reduction,” and by Lallemand’s internal and regulatory documents. (Id. at 25.)
Lallemand responds that DSM’s motion is nothing more than “a request for
reconsideration” of the court’s decision not to grant summary judgment of infringement,
purporting to quote the court at the colloquy while ignoring its ruling that this was all
evidence “that the jury should hear.” (Dkt. #209 at 6.) Lallemand also asserts that
Winge’s testimony at the colloquy was supported by and consistent with his earlier
opinions: (1) attributing TFY+’s reduced glycerol production to the pyruvate to ethanol
conversion and reduced NADH hindering glycerol production; and (2) opining not that
the Accused Products’ GPD2 deletion reduced glycerol production, but that DSM’s expert,
Dr. Stephanopoulos, had overstated its impact. (Id. at 7-8.) Lallemand further point out
2
that Winge’s opinion is bolstered by scientist Aaron Argyros’ testimony that “the metabolic
pathway is the primary driver of the glycerol reduction,” which “is what enables the glycerol
reduction.” (Id. at 8.) Finally, Lallemand adds that: (1) while Dr. Wenger acknowledged
that yeast lacking GPD2 had decreased glycerol synthesis, he was uncertain of the role of
GPD2’s reduction in the Accused Products’ glycerol production; and (2) the cited
regulatory document does not clearly tie reduced glycerol production to the knockout of
GPD2, but instead is a “simplification” of the metabolic pathways. (Id. at 9-10.)
The court largely agrees with Lallemand.
Having declined to grant summary
judgment on DSM’s claims of infringement, the jury will now determine whether the
Accused Products’ reduction of glycerol production is caused by the GPD2 deletion as
compared to corresponding wild-type cells. Accordingly, DSM’s MIL No. 1 is DENIED.
B. MIL No. 2: Exclude Argument and Evidence that Strains M8827 and M13021
Are Noninfringing Alternatives.
Next, DSM seeks to prevent Lallemand from arguing that strains M8827 and
M13021 were available, acceptable and noninfringing alternatives during the accounting
period because they “are not and never have been commercially available.” (Dkt. #185 at
6.) As support for this, DSM argues that Lallemand neither produced data showing how
these strains perform industrially, nor that they would be viable in the market. Without
this evidence, DSM contends, these stains are irrelevant to damages and would only
confuse the jury if admitted. (Id.) As support, DSM represents that developing a strain
from laboratory testing to industrial-scale production “is unpredictable and often fails,”
which it asserts is confirmed by Lallemand’s documents that show numerous strains were
3
unable to be translated from favorable laboratory testing to successful industrial-scale
production. (Id. at 7.) Without tests showing that strains M8827 and M13021 were
viable for industrial use, DSM asserts they were not commercially available, much less noninfringing substitutes under the Georgia Pacific factors.2
Lallemand acknowledges that the M13021 strain was not far enough along to be a
viable noninfringing substitute, but argues that the disagreement between experts on the
acceptability of strain M8827 is a factual question for the jury. (Dkt. #225-3 at 4 n.2;
dkt. #209 at 11.) In fact, Lallemand points to evidence that this strain was among
“dozens” of S. cerevisiae produced in its normal research and development, and was available
because “the necessary equipment, know-how, and experience existed to make and sell” it.
(Dkt. #209 at 11-12.) Lallemand further points to evidence that this strain would be
acceptable to customers, including that: (1) DSM “confirmed that customers would be
willing to switch products for an ethanol yield benefit of just 1%”; (2) other than the
Accused Products, there were no alternative yield-enhancing products in the market in
August 2014; and (3) as recognized by DSM’s Professor Alper, the M8827 strain produces
improved ethanol yields without knocking out the GPD2 gene. In contrast, Lallemand
asserts that a minimum 4% improvement necessary to change products, as asserted by
DSM’s damages experts, is unsupported by the evidence.
(Id. at 13-14.)
Finally,
Lallemand contends that whether this strain had yet to be commercialized is not dispositive
DSM explains that the market for bioethanol-producing yeast is unique in that ethanol producers
will not switch from one yeast to another without first conducting their own “commercial-scale trial
. . . at each respective facility to confirm performance under industrial conditions,” creating a
preference not to change products because of the need for this testing. (Dkt. #185 at 7-8.)
2
4
because: (1) the M8827 strain not only existed in 2014, but was considered during YP3’s
development; (2) “Lallemand . . . has the equipment, know-how, and experience to make
and sell genetically-engineered yeast products,” as demonstrated by Lallemand
commercializing three transgenic yeast products within five years; (3) Lallemand
performance tests using a proprietary fermentation protocol that more accurately predicts
a strain’s abilities to endure industrial conditions; and (4) Argyros, Mascoma’s director of
research and development, can testify about the viability of this strain at trial. (Id. at 1213.)
Again, the court largely agrees with Lallemand, since the viability of the M8827
strain appears to be a factual dispute for the jury to resolve. A technology need not be
available for sale during the accounting period to qualify as “an available, noninfringing
alternative.” See Micro Chemical, Inc. v. Lextron, Inc., 318 F.3d 1119, 1122 (Fed. Cir. 2003)
(citing Grain Processing Corp. v. American Maize-Prods. Co., 185 F.3d 1341, 1351-52 (Fed.
Cir. 1999)). Indeed, as Lallemand notes, the question of availability is generally factdependent. See id. at 1123.
Where the asserted alternative was not yet on sale, the burden shifts to the offering
party to establish availability. Grain Processing, 185 F.3d at 1354. This means Lallemand
will have the burden of proving it “‘had all of the necessary equipment, know-how, and
experience’” to produce and substitute the M8827 strain for the infringing product at the
time of infringement; whether the cost of material inputs for this alternative could make it
unavailable; whether the impacts of the changes were well known in the field; and whether
the infringer needed to design around the patented technology. Micro Chemical, 318 F.3d.
5
at 1123. In addition, Lallemand must prove that this strain would be “acceptable as a
substitute in the relevant market” as defined by consumer demand, which may be shaped
by “consumers’ intended use for the patentee’s product, similarity of physical and
functional attributes of the patentee’s product to alleged competing products, and price.”
Grain Processing, 185 F.3d at 1355.
Since all of the above are questions of fact for the jury, DSM’s MIL No. 2 is
DENIED as to strain M8827 and GRANTED as to M13021.
C. MIL No. 3: Exclude Evidence and Argument Concerning the Blomberg Assay.
Next, DSM seeks to exclude evidence and argument regarding the Blomberg assay
for the purpose of showing noninfringement, because it “does not measure the rate of
enzymatic production of glycerol,” which makes its results “irrelevant to Lallemand’s
noninfringement defense,” a waste of time, and misleading.3 (Dkt. #185 at 8-9.) In so
arguing, DSM repeats evidence offered at summary judgment that: (1) the Blomberg assay
determines whether an enzymatic activity occurs -- not a reaction rate -- in an in vitro
sample, and the ’998 patent used the Blomberg assay to confirm the absence of GPD
activity in a mutant lacking both GPD 1 and GDP2 genes as compared to the presence of
that activity in a corresponding wild-type strain; (2) the Blomberg assay “measures the
maximum theoretical capacity [kcat] of the Gpd1 enzyme under ideal conditions (e.g.,
saturating substrate conditions [E0] . . .) once the cells have by lysed,” instead of GPD
activity in yeast cells under fermentation conditions (and that the two may not be
Even so, DSM purports to reserve “the right to rely on Lallemand’s Blomberg assay results for the
purpose of showing willfulness in the damages phase of the case.” (Dkt. #185 at 11.)

correlated); and (3) GPD2 is unstable in the Blomberg buffer solutions so that the assay
cannot “accurately or reliably measure” GPD2 activity, making it inappropriate “for
measuring comparative Gpd activities,” as confirmed by Lallemand’s Blomberg assays that
had contradictory results. (Id. at 9-10.)4
As it did at summary judgment, Lallemand responds by arguing that DSM is seeking
to exclude evidence of disputed facts, even relying on “demonstrably false” reasons. (Dkt.
#209 at 15.) First, Lallemand notes that it has filed a motion for reconsideration which
explains why the court erred in finding that the ’998 patent’s only recognized measurement
of NAD-dependent GPD activity is the rate of glycerol production. (Id.) Since the court
take up the request to reconsider in a separate opinion, it will not address that motion
here. Second, Lallemand asserts, DSM’s argument that the Blomberg assay is irrelevant to
noninfringement is a non sequitur, because the Accused Products’ lack the GPD activity
recited in Term 2 and the “rate of enzymatic production of glycerol” is part of Term 3.
(Id.) This is at best an over-simplification of DSM’s argument, but Lallemand may so
argue provided that defense counsel and experts do not misrepresent the limitations of the
Bloomberg assays to measure in vivo (as opposed to in vitro) GPD activity.
Third,
Lallemand argues that even if DSM’s assertions were accurate, the requested relief is
overbroad because the Blomberg assay would be relevant to GPD activity, even if it didn’t
measure the activity rates (which, Lallemand argues it does), because enzyme capacity or
amount (as measured by Blomberg) factors into enzymatic activity. (Id. at 15-16.) Again,
On this last point, DSM also points to Professor Winge’s modifications to the Blomberg assay
buffer solution in an attempt to measure GDP2 activity are, as Winge acknowledged, unverified
and inadmissible under Rules 702 and 403. (Id. at 11.)
4
7
Lallemand may so argue -- since the patent itself suggests use of the Blomberg assays as a
meaningful test procedure -- provided its counsel and experts do not misrepresent its
relevance to measuring the rate of activity in vivo.
Where Lallemand goes off the rails is in asserting that the Blomberg assays may be
meaningful in ways already rejected by the court. First, the court rejects and Lallemand
may not argue that the Blomberg assay “measures the rate of the reaction catalyzed by
GPD.” Second, the claims in the patent concern fermentation, making the value of the
use of Blomberg assays to measure in vitro activity to confirm that a reduction in glycerol
production may be explained by something other than the elimination or reduction in GPD
activity, if at all.
Third and finally, Lallemand may not argue that GPD2 can
“indisputably” be measured with the Blomberg assay. Consistent with the above, therefore,
DSM’s MIL No. 3 in DENIED IN PART AND GRANTED IN PART.
D. MIL No. 4: Exclude Green’s Opinion on Damages.
DSM next seeks to exclude Phillip Green’s damages opinion under Rule 702
“because he does not rely on sufficient facts, makes improper assumptions, and fails to
reliably apply the relevant principles and methods to the facts of this case.” (Dkt. #185
at 11.)
DSM begins by explaining that Lallemand prices products by adding two
components: (1) the “Yeast Price Component,” which is the amount for the yeast at a perkg cost; and (2) the “MGT Price Component,” which is based on additional ethanol yield
for the Accused Products (or for TransFerm, the savings achieved through the lessened
8
need for glucoamylase).5 (Id. at 12.) Then, DSM notes that from 2012–2014, Lallemand’s
sale revenues for TransFerm were $25,503,431, with $13,447.419 coming from the MGT
Price Component; and from August 2014–September 2017, Lallemand’s sales revenues for
the Accused Products totaled $113,579,584, with $64,647,532 coming from the MGT
Price Component. (Id.) Accordingly, Dr. Jesse David, DSM’s damages expert, calculates
lost sales with a range of $32–$40 million from August 2014 to September 2017.
In contrast, Phillip Green, Lallemand’s damages expert, calculates damages for the
same period to be approximately $4.95 million.
(Id. at 13.)
DSM argues that this
calculation is based on the incorrect assumptions that Lallemand would have been able to
keep selling TransFerm and conventional yeast, as acceptable, non-infringing alternatives
at levels comparable to the actual sales of Accused Products.6
First, DSM argues that Lallemand cannot show that TransFerm and conventional
yeast would have sold comparably to the Accused Products, nor that either was an available
and acceptable, non-infringing alternative. (Id. at 15.) To the contrary, DSM points out
DSM notes that, by and large, the Accused Products replaced TransFerm, except for consumers
in the POET sub-market, who still purchase TransFerm. (Dkt. #185 at 12 & n.5.) Lallemand
clarifies that the MGT Component is a “technology fee” typically based on the number of
fermentations performed by a plant and that for TransFerm, the fee is based on savings from
reduced glucoamylase purchases, while for the Accused Products, the fee is based on those savings
plus the value of increased yield. (Dkt. #209 at 19-20.)
5
6
DSM also criticizes Green’s assumption that “strains M8827 and M13021 would have been
available and acceptable, non-infringing alternatives and would have been sold by Lallemand at
levels comparable to its sales of the Accused Products.” (Dkt. #185 at 13-14.) The court has
already addressed this criticism in denying DSM’s MIL No. 2 above. Similarly, DSM criticizes
Green’s assumption that sales of the M8827 strain would be comparable to those of the Accused
Products, despite offering a smaller yield enhancement and failing to consider other drivers of
consumer behavior. (Id. at 20-21.) For reasons addressed above, however, this, too, goes to the
weight that the jury should assign Green’s opinions, not to their admissibility based on his reliance
on those assumptions.
9
that TransFerm’s sales had “flattened” and decreased before the Accused Products hit the
market, something Green does not address.
(Id.)
Similarly, DSM criticizes Green’s
attributing Lallemand’s sale of the Accused Products to good customer relationships, when
only six customers continued buying TransFerm from 2012 to present rather than
switching to TransFerm Yield+ (and in greater quantities), despite the higher fermenter
fee. (Id. at 15-16 & n.7.) Accordingly, DSM argues that Green greatly underestimates the
value of the ’998 patent to Lallemand. (Id. at 17.) Second, DSM argues that neither
conventional yeast nor TransFerm is an acceptable alternative because neither provides
additional revenue or savings from glycerol reduction or yield enhancement.7 (Id. at 18.)
More specifically, DSM argues that Green’s opinion to the contrary must be excluded for
failing to account for this difference, the large increase in customer demand for the Accused
Products, and the potential savings from TransFerm being insufficient to cover the
transaction costs for abandoning conventional yeast. (Id.)
Lallemand responds that DSM’s arguments boil down to disagreement with Green’s
opinions, rather than their admissibility. (Dkt. #209 at 18.) Lallemand explains that
Green calculated a reasonable royalty for use of the patent “by considering a hypothetical
negotiation . . . in August 2014 and applying the fifteen factor test set forth in GeorgiaPacific,” which is the same framework used by DSM’s expert. (Id. at 21.) In Green’s
DSM illustrates: a hypothetical fermentation plant with a 100-million-gallon capacity would have
an additional $6.6 million of revenue from use of the Accused Products or would save $1 million
through use of TransFerm. Because these amounts would be split with Lallemand, this would result
in fractions of those amounts in savings or additional revenue for the producer. (Dkt. #185 at 18.)
DSM notes that use of conventional yeast would provide neither savings nor additional revenue.
(Id.)
7
10
opinion, the total profits and revenues associated with the Accused Products are not
representative of the patent’s value because the patent “does not claim yeast generally or
glucoamylase expression,” and these features’ value should be apportioned out.
(Id.)
Lallemand argues that Green appropriately focused his analysis on the benefits Lallemand
got from the patented technology, as he considered that:
(1) Lallemand could have
continued to sell TransFerm; (2) 80% of customers purchasing Accused Products in 2017
were already Lallemand customers; (3) Lallemand only marketed TransFerm briefly so it
had not yet penetrated the market when the Accused Products were launched to replace
TransFerm; and (4) Lallemand’s pricing structure at the time of TransFerm’s launch was
unfamiliar to the market, but familiarity increased by the launch of TransFerm Yield+.
(Id. at 25-27.) Further, Lallemand contends that Green’s opinion that TransFerm was an
available non-infringing alternative was proper and that DSM’s argument to the contrary
is flawed because the next-best available alternative (which need not have the patented
features) is considered in determining a reasonable royalty analysis.
(Id. at 27-28.)
Further, Lallemand explains that the appropriate comparison is between the noninfringing
alternative and the patent owner’s product, which is not possible here since DSM had not
yet commercialized that product. (Id. at 28-29.) Finally, Lallemand defends Green’s
apportionment of value between the patented invention, the wild type yeast, and features
not claimed by the patent, noting that “Mr. David effectively employs the entire market
value rule to capture almost the entirety of the profits Lallemand derives from the Accused
Products,” yet he failed to assess if and how yield improvement impacts market demand.
(Id. at 29-31.)
11
In applying Rule 702, a district court is to function as a “gatekeeper,” determining
whether a party’s proffered expert testimony is relevant and reliable. Daubert v. Merrell
Dow Pharmaceuticals, Inc., 509 U.S. 579, 589 (1993); see also United States v. Johnsted, 30 F.
Supp. 3d 814, 816 (W.D. Wis. 2013) (expert testimony must be “not only relevant, but
reliable”). Still, “[v]igorous cross-examination, presentation of contrary evidence, and
careful instruction on the burden of proof are the traditional and appropriate means of
attacking shaky but admissible evidence.” Daubert, 509 U.S. at 596.
Here, DSM’s
criticisms go almost entirely to the factual assumptions underlying Green’s opinions, not
to their admissibility. See Williams v. Illinois, 567 U.S. 50, 57, 132 S. Ct. 2221, 2228
(2012) (“Under settled evidence law, an expert may express an opinion that is based on
facts that the expert assumes, but does not know, to be true. It is then up to the party who
calls the expert to introduce other evidence establishing the facts assumed by the expert.”).
DSM may, of course, cross-examine him on those assumptions.
Likewise, DSM can
question him about how and why he apportioned value between the elements claimed in
the ’998 patent, a wild-type yeast cell, and unclaimed features. Accordingly, DSM’s MIL
No. 4 is DENIED.
E. MIL No. 5: Limit the Number of Prior Art Combinations Lallemand May
Present on its Obviousness Defense.
DSM seeks to limit the number of prior art combinations Lallemand can present to
“prevent” the “needless[] present[ation of] cumulative evidence,” thereby “ensur[ing] that
the jury’s time is not wasted” without “prejudic[ing] Lallemand in any way.” (Dkt. #185
at 21-22.)
Specifically, DSM explains that Lallemand has identified twelve prior art
12
combinations that it asserts render the ’998 patent obvious, but that Professor Winge
testified that the four primary references are “equivalent” and the three secondary
references are “equivalent,” effectively reducing the twelve combinations to two.8 (Id.)
Lallemand opposes this motion because: (1) “it seeks to solve a ‘problem’ that does
not actually exist”; and (2) “limiting Lallemand to only two specific prior art combinations
that DSM has selectively chosen would be unfairly prejudicial.” (Dkt. #209 at 32.) As to
the first, Lallemand explains that even if it were inclined to force Professor Winge to walk
the jury through the thirty-five pages of his report analyzing the combinations (which it
represents it is not), the trial schedule does not afford sufficient time to do so. (Id.)
Accordingly, Lallemand represents that it has already culled the prior art references it
intends to rely on at trial, as noted in the proposed jury instructions. 9 (Id.) As to the
second, allowing DSM to “cherry-pick two combinations which are most beneficial to its
own validity case would be unfairly prejudicial to Lallemand.” (Id. at 33.) Regardless,
Lallemand represents it plans to present two combinations of its own choosing to the jury
on obviousness.10 (Id.) Accordingly, DSM’s MIL No. 5 is GRANTED IN PART AND
DENIED IN PART by limiting Lallemand to those two combinations.
DSM summarizes the two combined references as: (1) “Nevoigt ’270, Zhang, Nissen or Guo in
view of Wahlbom or Sonderegger II (and Taherzadeh)” and (2) “Nevoigt ’270, Zhang, Nissen or
Guo in view of Mueller (and Taherzadeh).” (Dkt. #185 at 22.)
8
Lallemand specifies the five prior art references are: Sun, Nevoigt, Wahlbom, Sonderegger and
Valadi. (Dkt. #209 at 32.)
9
Specifically, these two combinations are: (1) “Nevoigt in view of Wahlbom” and (2) “Sonderegger
in view of Valadi.” (Id. at 33.)
10
13
F. MIL No. 6: Exclude Evidence and Argument Relating to the Replacement of
Stephanopoulos with Alper.
DSM next seeks to prevent Lallemand from attempting to impeach Professor Alper
“on the basis that his opinions have been substituted for those of Dr. Stephanopoulos,”
relying on the parties’ joint submission to the court in which they agreed that “‘neither
party will draw any inference from, or rely in any argument on, the unavailability and
replacement of Dr. Stephanopoulos.’” (Dkt. #185 at 22-23 (quoting dkt. #137 at 2).)
Specifically, DSM argues that allowing Lallemand to impeach Alper on the basis of
Stephanopoulos’s unavailability would result in unfair prejudice to plaintiffs. (Id. at 23.)
In response, Lallemand contends that it will not violate the parties’ agreement.
(Dkt. #209 at 34.) Rather, Lallemand argues that DSM is trying to “insulate Dr. Alper’s
opinions from fair-game criticism stemming from Dr. Alper’s own lack of diligence.” (Id.)
Specifically, as at the expert colloquy, Lallemand intends to establish that Alper failed to
“perform his own search of the scientific literature,” which goes to the weight of his opinion
that the Blomberg assay cannot measure GPD2 activity and does not concern
Stephanopoulos’s unavailability or replacement. (Id. at 35.)11
During the colloquy, Lallemand asked Alper: “The literature that you reviewed in your expert
report came from Dr. Stephanopoulos, from his report, didn’t it?” and “So for the purpose of
determining whether the Blomberg assay could measure GPD2 activity, you did not go into a
literature search to see if there were references that successfully reported GPD2 activity, did you?”
(See dkt. #209 at 34 (quoting dkt. #166 at 99:20-100:7).) Lallemand represents that Alper’s
deposition contains “essentially the same line of questioning.” (Id. at 34 n.11.) In the deposition
transcript, Alper testifies that he did not make changes from Stephanopoulos’s prior report; that
Stephanopoulos relied on the cited articles to support the opinion that GPD2 could not be
measured; and that Alper reviewed Stephanopoulos’s work and adopted his opinions. (Dkt. #172
at 55:15-56:6.) Then Alper was questioned about whether he conducted his own literature search
(no, but he had previously reviewed many of the cited papers in working on the invalidity report);
and then he testified that his review of the literature associated with Stephanopoulos’s report led
to his opinions. (Id. at 56:7-57:6.)
11
14
The parties agreed that they would not “draw any inference from, or rely in any
argument on, the unavailability and replacement of Dr. Stephanopoulos” (dkt. #137 at 2),
and they are still bound by that.
While their agreement does not create a blanket
prohibition on referencing the work of Professor Stephanopoulos, any reference should be
cleared in advance with the court outside the jury’s presence. By asking about how the
scientific literature reviewed was located and how Professor Alper came to his opinions,
Lallemand did not breach its agreement during pretrial discovery, including the colloquy.
However, in the case of Alper’s diligence in looking for further confirmation of the inability
of the Blomberg Assay to detect GPD2 activity in particular, Lallemand’s expert conceded
the same limitation at the colloquy, making any detour as to Alper’s reliance on
Stephanopoulos in this regard an unnecessary departure at best. Accordingly, DSM’s MIL
No. 6 is RESERVED pending a proffer by Lallemand as to any reference to Stephanopoulos
it believes may still be appropriate at trial.
II. Lallemand’s Combined Motions in Limine (dkt. #188)
A. MIL No. 1: Exclude Evidence from Certain Inventors of the ’998 Patent.
Lallemand seeks to exclude testimony, documents or other evidence from inventors
Victor Gabriel Guadalupe Medina and Antonius Jeroen Adriaan Van Maris because:
(1) Lallemand has been unable to contact them, as DSM has provided no contact
information; and (2) Mayer Brown, DSM’s counsel, declined to accept service on behalf of
Dr. Van Maris, despite previously informing Lallemand that it represented all of the
15
patent’s inventors. (Dkt. #188 at 7.)12 After Mayer Brown refused to accept service of
the subpoena, however, DSM served supplemental Rule 26 disclosures, still listing all three
inventors as people who may be relied upon to support DSM’s claims or defenses. (Id. at
8-9.)
Lallemand further adds that at the deposition of the final inventor, Dr. Jacobus
Pronk, Pronk testified that Mayer Brown had collected documents from him and Dr. Van
Maris, but only two documents were produced. (Id. at 9-10.) Lallemand argues that since
DSM claimed not to know where these witnesses were located, “it should be axiomatic that
DSM cannot call either of these inventors to testify at trial or offer into evidence
documents from them.” Otherwise, Lallemand argues, DSM’s game of “hide-the-ball”
would be rewarded. (Id. at 10.)
DSM responds that it “has not identified either [Van Maris or Medina] as a
potential trial witness,” making Lallemand’s complaints both “irrelevant” and untrue.
(Dkt. #212 at 1.) Instead, DSM explains, “Lallemand seeks to exclude evidence that does
not and will not exist in this case,” and its motion should be denied. Regardless, since
DSM is not calling either Medina or Van Maris, this motion is MOOT as to their
testimony.
This motion is further DENIED at this time as to documents, although
Lallemand can object individually to DSM’s proposed trial exhibits based on unfair
surprise, assuming it did not waive any objection by failing to ripen this issue through a
In DSM’s initial disclosures under Rule 26(a), Medina and Van Maris were identified as likely
having discoverable information that may be used to support DSM’s claims or defenses,
acknowledging that their exact addresses were unknown, but that “on information and belief” they
were associated with “Novozyme, in Curitiba, Parana, Brazil” and “KTH Royal Institute of
Technology, Stockholm, Sweden,” respectively. (Dkt. #188 at 7-8.)

timely discovery motion.
B. MIL No. 2: Exclude Evidence from Marco Mölling.
Lallemand next asks the court to exclude evidence from Marco Mölling, the lead
attorney who drafted and prosecuted the ’998 patent, because DSM did not produce any
evidence concerning him. (Dkt. #188 at 11.) Lallemand explains that while it “sought
documents and information concerning the preparation and prosecution of the ’998 patent
and its European counterpart,” DSM only produced a handful of documents concerning
Mölling and his firm, which DSM represented were the relevant, non-privileged documents
in its possession. Otherwise pointing to privilege logs, DSM produced only one document
relating to draft patent applications, while the remaining documents related to
communications to or with Mölling, two of which were produced and clawed back as
privileged.13 (Id. at 12-14.) Following this narrow production, Lallemand notes that DSM
added Mölling to its Supplemental Rule 26 Disclosures on the last day of discovery. (Id.
at 14.)
Accordingly, Lallemand argues that DSM should not be allowed to rely on
Mölling’s testimony or unproduced documents at trial after this conduct. (Id. at 14-15.)
While DSM responds that the limited evidence from Mölling is unsurprising, since
he was patent counsel to TU Delft, the original patent owner, and Lallemand chose to
subpoena TU Delft’s U.S. patent counsel instead of Mölling himself, DSM further notes
Lallemand also represents that it sought documents concerning Mölling’s involvement in the
preparation and prosecution of the patent from inventor Pronk and the U.S. Patent counsel, who
prosecuted the application, but received no communications and no additional privilege logs. (Dkt.
#188 at 13-14.) Since it appears that Lallemand sat on its rights by failing to seek to compel
production, these representations have little to no bearing on the court’s ruling here.
13
17
it did not identify Mölling as a trial witness, and Lallemand failed to identify any document
or evidence from Mölling that DSM intends to use at trial. (Id.) (Dkt. #212 at 2.) For
these reasons, Lallemand’s MIL No. 2 is DENIED AS MOOT, although it may object to
the use or admission of individual documents as applicable.
C. MIL No. 3: Exclude Evidence and Argument Concerning Preparation and
Prosecution of the ’998 Patent beyond What Is Contained in DSM’s Expert
Reports.
Lallemand next seeks to exclude evidence and argument about the preparation and
prosecution of the patent not contained in DSM’s expert reports because: (1) DSM’s
30(b)(6) witness, Atul Thakrar, was unable to answer questions about the ’998 patent’s
preparation and prosecution; (2) “Lallemand’s attempts to obtain discovery from or about
people familiar with the preparation and prosecution of the patent-in-suit . . . proved
futile”; and (3) DSM represented in response to an interrogatory that the only relevant
facts that it contends support its infringement claims are found within its experts’ reports.
(Dkt. #188 at 16.) Basically, Lallemand argues that DSM should “be limited to the record
that it disclosed during the fact and expert discovery period” and “be precluded from
presenting evidence or argument at trial inconsistent with its interrogatory answers” to
avoid unfair surprise and undue prejudice. (Id. at 17-18.)
DSM opposes this motion explaining that: (1) DSM only purchased the patent
from TU Delft after it was issued, thus it is unsurprising that DSM’s 30(b)(6)
representative was unable to provide certain information about prosecution of the patent;
(2) Lallemand failed to subpoena the people involved in the prosecution, including
Mölling, Van Maris and Medina, so the lack of discovery is Lallemand’s own doing;
18
(3) DSM is not limited to prosecution statements identified in Professor Alper’s report;
and (4) DSM is entitled to rebut Lallemand’s use of prosecution history at trial. (Dkt.
#212 at 2-3.)
In addition to its Rule 26(a)(1) disclosure obligations, Lallemand specifically
requested by interrogatory that DSM “[i]dentify any fact concerning the preparation,
filing, prosecution, examination, or maintenance of the ’998 Patent that DSM contends
supports its infringement contentions.” (Dkt. #191-17 at 10.) On December 22, 2017,
DSM substantively responded “direct[ing] Lallemand to the expert reports of Dr. Gregory
Stephanopoulos.”14 (Id.) Rule 33 requires that “[e]ach interrogatory . . . to the extent it
is not objected to, be answered separately and fully in writing under oath.” Fed. R. Civ. P.
33(b)(3) (emphasis added). One purpose of interrogatories is to identify evidence or to
point a party to where it may find such evidence. See U.S. v. 216 Bottles, More or Less,
Sudden Change by Lanolin Plus Lab. Div. Hazel Bishop Inc., 36 F.R.D. 695, 701 (E.D.N.Y.
1965) (“The purpose of the interrogatories is to discover facts or to learn where such facts
are available and to narrow the issues of fact.”). Finally, DSM was under an obligation to
update its initial Rule 26 disclosures and interrogatory responses as it acquired additional
information under Rule 26(e). See Barker v. Bledsoe, 85 F.R.D. 545, 548 (W.D. Okla. 1979)
(“Answers given at initial stages of discovery are not expected to be final, and are not
binding to the party giving them. Thus the duty of supplementing answers.” (internal
citations omitted)). To the extent DSM failed to meet these obligations, it is unfair for
Lallemand notes that the references included in Stephanopoulos’s reports are also found in
Professor Alper’s substitute infringement report. (Dkt. #188 at 17.)
14
19
DSM rely on this information at trial. Accordingly, this motion is GRANTED and DSM
may only rely on the information timely disclosed under Rule 26 and in response to
discovery requests, including for infringement purposes, only what was disclosed in its
expert reports concerning preparation, prosecution and maintenance of the ’998 patent in
response to Lallemand’s specific interrogatory on that subject.
At the final pretrial
conference, DSM may still proffer any other information related to the preparation,
prosecution and maintenance of the ‘998 patent not in its expert report that is maintains
was timely disclosed or need not have been disclosed for impeachment purposes for the
court’s consideration. Otherwise, all such information will be excluded from trial for any
purpose.
D. MIL No. 4: Preclude DSM from Offering Evidence or Argument Concerning
Firestart on Damages.
Next, Lallemand seeks to prevent DSM from introducing evidence or argument
about DSM’s Firestart project and related yeast, which Lallemand believes DSM will use
to try to demonstrate the competition between the two companies “in the first-generation
yeast market” to establish that DSM “would have demanded a higher royalty.”15 (Dkt.
#188 at 19.) Lallemand’s basis for seeking exclusion is that the Firestart project would
have been irrelevant to a hypothetical negotiation between the parties because it was not
Lallemand explains that the difference between first- and second-generation ethanol production
is the input: in the former, “production uses starch or sugar-based materials”; while in the latter,
production “uses cellulosic feedstock,” such as wood, grass, and crop residues. (Dkt. #188 at 13
n.6.)
15
20
conceived until almost a year after the hypothetical negotiation.16 (Id.) Accordingly,
Lallemand argues that evidence of this project would be irrelevant, unfairly prejudicial,
misleading and confusing to the jury. (Id.) Specifically, Lallemand contends that: (1) time
would be wasted and the jury confused by the introduction of an unrelated complex
technology for genetically modifying yeast; and (2) Lallemand would be prejudiced by the
implication that DSM planned to enter the first-generation yeast market before it did,
suggesting a higher royalty would be appropriate. (Id. at 23-24.)17
DSM responds that the Firestart product is not irrelevant, as seen by Professor
Winge examining the strains and opining that they do not fall under the ’998 patent and
Lallemand’s damages expert referencing Firestart in calculating his proposed reasonable
royalty. (Dkt. #212 at 3.) The court agrees that Lallemand cannot have its cake and eat
it too -- Lallemand cannot prevent DSM from relying on evidence that Lallemand itself
relies on. However, Lallemand’s proposed reply on this motion “represents that neither it
nor any of its witnesses (fact or expert) intend to utter the word ‘Firestart’ unless DSM is
allowed to introduce it into this case.” (Dkt. #225-1 at 6.)
This brings the court back to the question of Firestart’s relevance to DSM’s damages
case. On this, Lallemand has made a convincing case for excluding Firestart as evidence of
Lallemand explains that Firestart was spearheaded by Atul Thakrar, who joined DSM in May
2015, and that DSM had no intention of designing first-generation yeast before his arrival. (Id. at
19-20.) Instead, DSM worked on second-generation yeast exclusively from 2008–2014. (Id. at
20.) Further, Lallemand contends that Firestart only resulted in commercially-viable strains in
August 2017, when DSM filed a Microbial Commercial Activity Notice for five yeasts (none of
which practice the patent) and DSM began large-scale testing of a Firestart strain in October 2017.
(Id.)
16
At the same time, Lallemand concedes that its motion is not directed towards DSM’s ability to
argue about the parties’ competition as relates to DSM’s request for injunctive relief. (Id. at 24.)
17
21
competition, since it appears undisputed that Firestart was the brainchild of Thakrar, a
DSM employee, who only joined DSM’s ranks in 2015, meaning that Firestart was not
even on the horizon at the time DSM would have entered into the hypothetical negotiation
in August 2014. The existence of a noninfringing alternative is considered throughout the
accounting period, however for it to be a factor at the hypothetical negotiation, it must at
least be conceptualized by that point. Accordingly, Lallemand’s MIL No. 4 is GRANTED
unless it opens the door by introducing evidence or argument relating to Firestart into the
trial record.
E. MIL No. 5: Preclude DSM from Offering Argument Concerning Competition
between the Parties in the First-Generation Ethanol Production Market.
Similarly, Lallemand seeks to prevent DSM from arguing or suggesting that the
parties compete in the first-generation ethanol production market, arguing that “DSM has
produced no evidence showing actual competition,” meaning any argument “based on
purely illusory competition” should be excluded under Rules 402 and 403. (Dkt. #188 at
25.) As an initial matter, Lallemand explains that the Accused Products are used in firstgeneration ethanol production, while DSM was exclusively concerned with the secondgeneration market until May 2015.
Moreover, Lallemand contends that there is no
evidence that the Firestart strains compete with the Accused Products because: (1) DSM
has not sold them; (2) internal speculation is insufficient to establish market behavior;
(3) DSM has not settled on a pricing strategy for these strains; and (4) DSM conducted
“pilot trials” only in October 2017, after this litigation was underway yet declined to make
the results of those trials available for the depositions of relevant employees. (Id. at 25-
22
27.)
DSM again argues that Firestart is relevant because: Lallemand’s experts considered
it; “Firestart is DSM’s new first-generation yeast product that was recently approved for
commercialization”; and the October 2017 test showed an average 3% ethanol yield
increase over TFY+. (Dkt. #212 at 4.) DSM adds that “Lallemand’s complaints of lack
of sales or pricing as of mid-December 2017” lack merit because Firestart was only recently
approved and DSM continues to commercialize Firestart.
(Id. at 5.)
Finally, DSM
contends Lallemand’s concerns about discovery are “baseless” as Lallemand sought these
additional fact depositions after the close of fact discovery. (Id.)
Lallemand again has the better argument. Because DSM’s initial foray into firstgeneration ethanol production began in 2015 and has not yet been successfully
commercialized, DSM cannot say that it directly competes with Lallemand or the Accused
Products through Firestart. On the contrary, the evidence appears to show Firestart only
began yielding preliminary results (regulatory approval and industrial-scale testing) in
2017. Accordingly, Lallemand’s MIL No. 5 is GRANTED absent DSM proffering at the
final pretrial conference timely-disclosed evidence of a basis for such an argument other
than Firestart.
F. MIL No. 6: Preclude DSM from Offering Evidence or Argument Concerning
DSM’s Products that Embody the ’998 Patent.
In yet another motion criticizing DSM’s discovery conduct, Lallemand next argues
that DSM should be prevented “from introducing evidence or argument concerning sales
of any products DSM now alleges embody, practice, are covered by, or use any claim of
23
the ’998 patent” because in an interrogatory answer, “DSM represented that it had ‘not
sold any products that embody, practice, are covered by, or use any claim of the ’998
patent,’” only to change its tune three weeks and then mere hours before discovery closed
to assert one, and then three, such products were sold. (Dkt. #188 at 28 (internal citation
omitted).) More specifically, Lallemand explains that eleven months after DSM’s initial
interrogatory answer quoted above, DSM’s employee identified one yeast product that
practiced the patent (SCY-LIB 4). (Id. at 29.) Then, two weeks later, DSM produced
documents relating to multiple yeast strains, including documents indicating an intent to
commercialize DY-LIB and DY-LIB 3. (Id. at 29-30.) Finally, DSM supplemented its
interrogatory response on the last night of discovery to identify three “commercial
products” -- SCY-LIB 4, DY-LIB, and DY-LIB 3 -- that DSM “manufactured, used, and
sold,” each of which were “covered by at least claims 1, 5, and 7 of the ’998 patent.” (Id.
at 30.)
First, Lallemand argues that DSM failed to supplement its discovery responses in a
timely fashion, as required under Rule 26(e), because it waited until the end of discovery
to “completely reverse[] course,” even though it had obtained approval to sell two of the
strains in 2016 and began selling the third in early 2017. (Id.) Second, Lallemand argues
that preclusion is the appropriate sanction because: (1) Lallemand could not fully conduct
discovery into these three products; (2) the prejudice cannot be corrected because discovery
has closed, the deposition testimony of DSM’s employee was contradicted by the revised
interrogatory response, and the documents about commercializing these three strains
should have been produced earlier; (3) trial would be disrupted by the inclusion of the
24
issue of patent marking, which otherwise would not be relevant; and (4) because 2015
Microbial Commercial Activity Notices indicate that these products were covered by the
’998 patent, and DSM sought and obtained regulatory approval to commercialize two of
the strains and sold the other well before the close of discovery, DSM has no justification
for its delay in disclosing them. (Id. at 31-34.)
Alternatively, Lallemand requests that DSM be prevented “from presenting any
evidence or argument concerning marking these products with the ’998 patent number.”
(Id. at 28.)
Lallemand explains that patent holders can only recover post-filing
infringement damages unless it marked the products it sold with the patent number or gave
pre-suit notice of infringement. (Id. at 35.) Recognizing the question of notice is for the
jury, Lallemand nevertheless argues DSM should not be able to argue that it marked its
products because of (1) the delayed identification of products sold that embody the patent,
and (2) DSM’s failure to produce evidence of marking the products it now claims to have
sold. (Id.)
DSM responds by arguing that “Lallemand had every opportunity to depose DSM
witnesses on the subject of all three commercial strains and, in fact, did so,” as Lallemand
deposed DSM’s 30(b)(6) witness and a DSM scientist who worked on the development of
DY-LIB and DY-LIB 3. (Dkt. #212 at 6.) Further, DSM faults Lallemand for failing to
ask DSM’s witnesses if the products were marked, thereby waiving its argument as to
patent-marking. (Id.) Regardless, DSM further contends that it did not have an obligation
to mark products because Lallemand had notice of the infringement claim in 2015, and it
is entitled to damages over the entire infringement period since any failure to mark was
25
“excus[ed].” (Id. at 7.) DSM closes by claiming to have “promptly” supplemented its
interrogatory response, produced responsive documents, and offered two witnesses for
deposition. (Id.)
In fact, there was nothing “prompt[]” about DSM’s last-minute supplementation.
DSM responded first in January 2017, and then it failed to update the interrogatory
response until December of that year. The court cannot conceive of a good reason for
DSM not identifying these three products earlier. Arguing that Lallemand failed to ask
the right questions of DSM’s witnesses in deposition misses the point as well. Why would
Lallemand question DSM witnesses about commercialized yeast strains, including whether
they were marked with the patent number, unless DSM had timely supplemented its initial
interrogatory response?18
In the end, DSM fails to provide any reason for delaying the disclosure of sales that
took place in 2016 and early 2017. The court is left to conclude that DSM either failed
to take its responsibilities in responding to discovery seriously or was sandbagging
Lallemand on its sale of products embodying the ’998 patent. Either way, Lallemand’s
MIL No. 6 is GRANTED.19
In its proposed reply, Lallemand adds that DSM scientist Paul Klaassen (who was involved in
the development of DY-LIB and DY-LIB-3) testified at his deposition that he was “not so much
involved” with sales and did not know about sale figures. (Dkt. #225-1 at 11.)
18
The court is perplexed by DSM’s argument, citing to 35 U.S.C. § 287(a), that Lallemand would
be responsible for damages going back to August 2014, even if DSM had not marked the products.
(Dkt. #212 at 7.) Section 287(a) provides that
19
In the event of failure so to mark, no damages shall be recovered by
the patentee in any action for infringement, except on proof that the
infringer was notified of the infringement and continued to infringe
thereafter, in which event damages may be recovered only for
26
G. MIL No. 7: Strike New Opinions in the 2018 Alper Report.
Lallemand next seeks to prevent DSM from offering Alper’s new opinions contained
in his substitute report, arguing that the substitution of Professor Stephanopoulos’s report
“was never intended to give DSM free rein to inject new expert opinions into this case”
and “DSM should not profit from the accommodations necessitated by its own expert’s
medical issues.” (Dkt. #188 at 37.) Lallemand explains that it agreed to a schedule
allowing DSM to replace Stephanopoulos and serve a substitute report, but that it never
agreed to allow DSM to provide new expert opinions. (Id. at 37 & n.17.) Lallemand then
identifies ten sections of Alper’s report that it contends contain new opinions. (Id. at 38.)
Lallemand further contends it was prejudiced by these new sections because of the “short
period of time to respond,” Alper’s inability at his deposition to answer questions about
his new opinions, and Alper’s failure to provide calculations and data for these new
opinions.
(Id. at 39.) Lallemand then goes through the new categories of opinions,
explaining why each should be struck. (Id. at 39-45.)
In response, DSM argues that there is no unfair prejudice in Professor Alper offering
additional opinions because the parties recognized that his substitute report could contain
additional or revised opinions, and Lallemand had the opportunity to address these new
opinions in supplemental reports by Professor Winge and Mr. Green. (Dkt. #212 at 7-8.)
The parties’ joint motion for new trial date explains that the “revised schedule will
infringement occurring after such notice.
35 U.S.C. §287(a). Accordingly, without proof of marking, DSM’s potential damages would only
have started accruing once Lallemand was on notice of the claim, a date that remains for the jury
to decide.
27
allow time for the plaintiffs to retain an expert to substitute for Dr. Stephanopoulos and
provides the defendants the opportunity to depose the plaintiffs’ new expert and to
respond to any revised or new expert opinions.” (Dkt. #137 at 1.) In fairness, the motion
also notes that “[d]efendants reserve all their rights to seek appropriate relief from the
court in the event any new opinions and/or facts are provided in the substitute report.”
(Id. at 2.) During the telephonic status conference, the court recognized that DSM’s
substitute expert “will either have to adopt Dr. Stephanopoulos’s report and deposition
and stand on [them] or he will want to add some kind of modified report, which would
probably require some additional discovery.” (Dkt. #139 at 6:20-24 (emphasis added).)
While DSM’s counsel was “hopeful that [the substitute expert] would provide opinions
that are consistent and equivalent to what Dr. Stephanopoulos has already provided in his
report,” he also noted that “the two potential experts [they had] talked with [could ] not
commit to that because they ha[d]n’t really delved into the information” yet. (Id. at 7:1318.)
Recognizing that it would prejudice Lallemand to maintain the original trial
schedule, thereby allowing DSM to disclose its new expert less than a month before trial
(id. at 8:6-8), the court proposed alternate trial dates, directing DSM to provide “definitive
dates as to when an alternative expert will be able to provide . . . an updated report and
then [be] produced for deposition” (id. at 8:16-7:2). In setting those new dates, therefore,
both sides and the court recognized that DSM’s substitute expert could have opinions
different from or in addition to those of Dr. Stephanopoulos.
(See id. at 9:12-14
(recognizing that Lallemand might even want to choose a different response expert based on
28
the content of this substitute expert report).)
Considering that Lallemand had the opportunity to respond and its experts did
respond to Alper’s additional opinions, there is no sound reason to exclude these opinions
on the basis of timeliness. Indeed, even if, as Lallemand contends, additional fact discovery
was necessitated by the new expert report, it should have asked for additional discovery
instead of waiting until the eve of trial to complain. Accordingly, Lallemand’s MIL No. 7
is DENIED.
H. MIL No. 8: Preclude DSM from Offering Self-Serving Evidence as Objective
Evidence of Non-Obviousness.
Lallemand further asks the court to prevent DSM from presenting self-serving
documents as objective evidence of non-obviousness, arguing that industry praise provided
by a patentee or patent owner “has little probative value.” (Dkt. #188 at 45.) Specifically,
Lallemand identifies a TU Delft press release forwarded from Professor Ingledew to
Lallemand employees, titled “Here is a likely important advance!!” and argues that the
subject line has little to no probative value, as the email fails to connect the purported
praise to the invention, and the press release “contains only the self-serving statements of”
the patent owner, TU Delft, and inventor, Jack Pronk. (Id.) Finally, Lallemand contends
that this email would mislead and confuse the jury because the jury (1) is unlikely to
recognize that the press release’s praise is from the inventor and patent-holder and
(2) would view the subject line as sponsoring the press release’s content. (Id. at 46.)
DSM responds that it does not intend to rely on the press release itself as evidence
of industry praise, instead it intends to rely on the statement by Professor Ingledew that
29
the patented technology marks an “important advance!!” Moreover, there appears to be
an appropriate nexus between Ingledew’s statement and the patent: Dr. Ingledew was
referencing the Medina publication, which disclosed the same yeast as the patent. (Dkt.
#212 at 8-9.)
As DSM has represented that it intends only to rely on the statement by Professor
Ingledew, the court will focus on whether that statement has sufficient nexus to the ’998
patent. The email’s title is “Here is a likely important advance!!” and the only text in
addition to the press release is the comment “Please see below originating from the Delft
yeast group. Mike.” (Dkt. #45-13 at 1.) The press release’s synopsis notes that “[t]he
invention was published in the scientific journal ‘Applied and Environmental
Microbiology,’” the press release concludes with “[p]ublished at Guadalupe Medina et al.
Appl. Environ. Microbiol. doi:10.1128/AEM.01772-09,” and the factual description of the
invention describes decreased glycerol production and acetate consumption. (Id. at 1-2.)
Accordingly, Ingledew’s praise circulated to Lallemand’s own employees is tied closely
enough to the patent to be probative. Lallemand may address any concerns it has about
jury confusion during trial. Lallemand’s MIL No. 8 is, therefore, DENIED.
I. MIL No. 9: Preclude DSM from Offering Evidence or Argument Concerning
Lallemand’s Initial Licensing Communications with TU Delft.
Lallemand next seeks to exclude argument and evidence about its communications
with TU Delft about licensing the patent, arguing that the communications’ probative
value concerning non-obviousness of the ’998 patent would be substantially outweighed
by the risk of misleading the jury in its assessment of whether Lallemand needed or wanted
30
to license the patent. (Dkt. #188 at 47.) In its motion, Lallemand acknowledges having
preliminary communications with TU Delft in 2014 about possibly licensing the patent,
but contends that these emails are “introductory and preliminary in nature,” did not
include “substantive discussions of the patent itself or licensing terms,” and “are not
evidence of actual licensing.” (Id.) Further, Lallemand adds that the emails did not
concern the Accused Products. (Id.)
DSM argues that this request should be denied for two reasons: (1) Lallemand’s
desire to license the patent is “a relevant secondary consideration of non-obviousness” as
both Mascoma and Lallemand sought to license the technology; and (2) Professor Alper
established a connection between the patent and Lallemand wanting to license it. (Dkt.
#212 at 9-10.) As to the first, DSM argues that Lallemand’s reasons for attempting to
license the patent are relevant to secondary considerations and quotes two emails to
inventor Pronk: (a) Lallemand informing him that “we have read with interest your recent
publication” and “would very much like to have a chance to discuss with you opportunities
to work together to bring this technology to industry”; and (b) Mascoma writing “[w]e are
interested in finding out more,” and “[t]his technology would be valuable to our
lignocellulosic ethanol CBP process,” before closing with “[a]s always it’s great to read of
your path-breaking discoveries!” (Id. at 9-10 (quoting dkt. #210).) As to the second,
DSM explains that a connection between the Accused Products and the patent is not
necessary, but rather the nexus must be between the secondary consideration and the
patent. (Id. at 10.)
The defendants’ potential interest in licensing the ’998 patent is relevant to the
31
whether the patent was obvious because that interest indicates that the invention was new.
See Ormco Corp. v. Align Tech., Inc., 463 F.3d 1299, 1311 (Fed. Cir. 2006) (quoting Graham
v. John Deere Co., 383 U.S. 1, 17-18 (1966)). Lallemand’s concern about the jury confusing
potential interest in licensing with a need to license can be addressed through argument (or
if necessary, an appropriate jury instruction), while Lallemand’s concern that the jury may
think the defendants wanted to license is exactly why these documents are relevant.
Moreover, because of the preliminary nature of the emails and the fact of this lawsuit, it is
highly unlikely that the jury would infer that a license ever issued. Finally, that the emails
do not concern the Accused Products is irrelevant because the emails clearly concern the
’998 patent. See id. at 1311-12. Accordingly, Lallemand’s MIL No. 9 is DENIED.20
J. MIL No. 10: Exclude Certain Internal Lallemand and Patent Documents and
Related Expert Testimony.
Lallemand also challenges Professor Alper opinion that it “copied the ’998
technology” based on his review of Lallemand’s documents and patent filings. (Dkt. #188
at 49.) Lallemand argues that the documents Alper relied on do not relate to copying, do
not clearly show a nexus between the alleged copying and the Asserted Claims, and would
be highly prejudicial if admitted during the liability phase of trial. (Id.) Accordingly,
Lallemand seeks to exclude as proof of copying certain internal documents and patent
filings that refer to an article by Medina et al., Elimination of Glycerol Production in Anaerobic
In its reply, Lallemand raises a concern about Professor Alper tying communications from
defendants about possible licensing to the Accused Products and defendants’ need for a license.
(Dkt. #225-1 at 12.) Reviewing the excerpted portion of Alper’s report, these concerns are
overblown, except to the extent that Alper will not be allowed to opine about the reason for
Lallemand’s interest because he has no specialized knowledge in interpreting others’ motives
20
32
Cultures of a Saccharomyces cerevisiae Strain Engineered to Use Acetic Acid as an Electron Acceptor.
(Id. at 49-50.) Lallemand argues that (1) this article and the ’998 patent do not provide
the same information; (2) the Accused Products differ from the Medina disclosure because
they only knock out GPD2, not both GPD1 and GPD2, and Medina does not disclose the
addition of a bifunctional acetaldehyde/alcohol enzyme; and (3) allowing DSM to argue
that the references show copying would confuse the jury and prejudice defendants. (Id. at
50-51.)
Lallemand further argues that three cited patent filings could not have copied the
’998 patent because they were filed before the ’998 patent was published, plus in Example
1 those filings do not copy the Medina disclosure, but “merely acknowledges that the strain
taught by the Medina reference is not suitable for industrial application.” (Id. at 51-52.)
Specifically, Lallemand argues, the documents recognize that acetate inhibits cell growth,
while Medina showed that a yeast cell can be genetically modified to convert acetate to “a
less
inhibitory
compound,”
without
suggesting
the
addition
of
a
bifunctional
acetaldehyde/alcohol dehydrogenase to yeast and deleting either GPD1 or GPD2 -- neither
of which was suggested by Medina. (Id. at 52-53.) As to its own internal documents,
Lallemand again contends that because Medina does not disclose a single-knockout yeast
strain or the addition of a bifunctional acetaldehyde/alcohol dehydrogenase -- both features
found in the Accused Products -- those products could not have been copied from the
Medina reference, making Alper’s discussions of that reference misleading and irrelevant.
33
(Id. at 53-54.)21
DSM responds that the evidence Lallemand identifies “should not be excluded
because it demonstrates the source of Lallemand’s copying and the nexus to the merits of
the invention claimed in the ’998 patent.” (Dkt. #212 at 11.) First, DSM argues that
Medina’s research taught for the first time combining mutations to the GPD genes with
acetylating acetaldehyde dehydrogenase activity, and these features were claimed in the
’998 patent. (Id.) Professor Alper further concluded both Medina and the patent disclosed
these properties in the IMZ132 strain. (Id.) While acknowledging that Medina only
considered a GPD double knockout strain, DSM notes that the patent claims both doubleand single-knockout strains, contending that one of ordinary skill would see the benefit of
a single knockout strain upon reading Medina. (Id.) DSM’s position, of course, is that
“Lallemand’s argument that its bifunctional acetaldehyde/alcohol enzyme negates
Medina’s nexus to the claimed invention is of no moment because such enzyme has the
claimed AADH activity as does the AADH taught in Medina,” and Medina “expressly
suggests optimizing kinetics with a faster AADH enzyme.” (Id.)
Second, DSM argues that Lallemand’s frequent “citation to and use of” Medina is
“a common thread in Lallemand’s patent filings” and internal documents, and
“Lallemand’s attempts to distinguish . . . based on the use of ‘bifunctional
Lallemand more clearly articulates its arguments in its proposed reply brief, contending that since
DSM cannot establish that it copied the ’998 patent’s invention, because the Medina article
preceding the patent failed to disclose either of the essential features of the Accused Products -- the
deletion of only the GPD2 gene or a bifunctional acetaldehyde/alcohol dehydrogenase -- DSM’s
argument that Lallemand copied aspects of the Medina article would only confuse the jury. (Dkt.
#225-1 at 14-15.)
21
34
acetaldehyde/alcohol dehydrogenase’ enzyme is not credible in view of the overwhelming
evidence that such enzyme has the AADH activity taught by Medina and the ’998 patent.”
(Id. at 12.) Finally, DSM argues Professor Alper’s expert opinions would be helpful to the
jury. (Id.)
In order to establish copying as a secondary consideration of nonobviousness,
however, a patent-owner must offer “evidence of efforts to replicate a specific product.”
Wyers v. Master Lock Co., 616 F.3d 1231, 1246 (Fed. Cir. 2010) (emphasis added). This
prevents all competing products arguably falling within a patent’s scope from suggesting
that a patent is nonobvious. Id. (quoting Iron Grip Barbell Co. v. USA Sports, Inc., 392 1317,
1325 (Fed. Cir. 2004)). Here, DSM cannot point to the Medina publication (or a citation
to it) as evidence of copying because its disclosures are not identical to the patented
invention and lack two features that are alleged to infringe the patent. Regardless, allowing
Professor Alper to opine that undisclosed features were somehow “copied” from the
Medina article would confuse the jury.
Accordingly, Lallemand’s MIL No. 10 is
GRANTED.
K. MIL No. 11: Preclude DSM from Offering Evidence or Argument on
Infringement of Claims other than the Asserted Claims.
Lallemand argues that “evidence and argument related to the importance or
infringement of claims other than the Asserted Claims . . . should be excluded because any
alleged relevancy they may have is outweighed by the substantial risk of misleading the
jury and sowing juror confusion.” (Dkt. #188 at 55.) In particular, Lallemand objects to
the introduction of internal comments made in February 2011 on the broadness of the
35
international patent predecessor (and the resulting patent cooperation treaty application
(the “PTC application”)), noting that the “[f]irst claim . . . potentially impacts all of our
current metabolic engineering approaches.” (Id. at 55-56 (quoting dkt. #192-11 at 1).)
Lallemand argues that this internal document has no more than marginal relevancy because
the claim addressed was greatly narrowed before the ’998 patent issued, and accordingly
Alper’s reliance on it in forming his opinion on non-infringing alternatives was improper.
(Id. at 57.) Further, Lallemand contends that admitting this document and other evidence
related to unasserted claims would mislead and confuse the jury. (Id. at 57-58.)
Similarly, Lallemand argues that DSM should not be able to reference or discuss
patents not covering the Accused Products as there is little evidence of them in the record,
they are “only marginally relevant,” and introduction of such evidence “would inevitably
lead to juror confusion.” (Id. at 58.) For example, Lallemand argues that Alper’s opinion
that Firestart is covered by the 6,265,186 patent is based only on DSM’s prior statements,
rather than his own independent analysis. (Id. at 58-59.)22
DSM argues that this evidence should be admitted into evidence. (Dkt. #212 at
13.) As to the February 2011 meeting agenda in particular, DSM argues that it shows:
(1) “Lallemand routinely obtains freedom-to-operate clearance when developing its
products,” as the agenda notes a need for “a clear statement re FTO for Ethanol Red”; (2)
Lallemand knew of the “potential legal impact” of the patent in February 2011; and (3)
“Lallemand routinely monitored the intellectual property landscape.” (Id.) Accordingly,
Lallemand also argues that evidence of patents covering genetically-modified yeast products that
are sold by third-parties be excluded (dkt. #188 at 59), an argument addressed more fully in § II.L
infra.
22
36
DSM contends that the agenda is “highly relevant to” both noninfringing alternatives and
willfulness. (Id.) Further, DSM explains that Lallemand’s request for exclusion “misses
the point” because the “PCT application discloses the same subject matter as the ’998
patent,” even if claim 1 was broader, and believing that the conversation at that meeting
focused solely on claim 1 is unreasonable. (Id. at 14.)
As to the ’186 patent, DSM argues “it shows that the underlying technology is not
available to Lallemand as a noninfringing alternative.” (Id.) DSM contends that Alper’s
opinion is not conclusory as he relied on the evidence contained in DSM’s Firestart
Microbial Commercial Activity Notice, in which DSM certified the information provided
was “complete and truthful.” (Id.) Further, DSM argues that Lallemand failed to identify
a reason that the jury would be confused by the introduction of this evidence, adding that
any possible confusion could be mitigated with a jury instruction. (Id. at 14-15.)
While DSM is correct that the February 2011 agenda may be relevant to willfulness
and noninfringing alternatives, the first claim in the PTC application is broader than that
finally encompassed in the ’998 patent. (Compare dkt. #1-1 at 40 with dkt. #192-12 at
49.)23 This, combined with the fact that the PTC application is referred to in the agenda
23
Claim 1 of the ’998 patent provides:
Transgenic yeast cells comprising one or more recombinant
heterologous, nucleic acid sequences encoding a protein with NAD+dependent acetylating acetaldehyde dehydrogenase activity (EC
1.2.1.10),
wherein said cells lack enzymatic activity needed for the NADHdependent glycerol synthesis, or
said cells have a reduced enzymatic activity with respect to the
NADH-dependent glycerol synthesis
compared to a corresponding wild-type yeast cell, and
wherein said cells are free of NAD-dependent glycerol 3-phosphate
dehydrogenase activity or have reduced NAD-dependent glycerol 3-
37
as the “latest Pronk patent” does pose a serious risk of juror confusion. Specifically, the
jury could confuse the scope of the PTC application’s claim 1 with the final, narrower terms
of claim 1 in the ’998 patent. Further, DSM’s intent to argue, explicitly or implicitly, that
this single agenda demonstrates that Lallemand “routinely” sought freedom-to-operate
clearance underscores the potential confusion the introduction of this evidence may have,
especially when based on one reference to “need[ing] a clear statement re FTO for Ethanol
Red.” (See dkt. #192-11 at 2.) Accordingly, the February 2011 agenda is excluded.
As to evidence and testimony concerning the ’186 patent, the court starts from the
premise that Firestart is of limited relevance for reasons discussed earlier in this opinion.
See §§ II.D-E supra. Lallemand does not appear to argue that Firestart was a noninfringing
phosphate dehydrogenase activity compared to corresponding wildtype cells, and/or
wherein the cells are either free of glycerol phosphate phosphatase
activity or have reduced glycerol phosphate phosphatase activity
compared to corresponding wild-type cells, and
which comprise a genomic mutation in at least one gene selected
from the group consisting of GPD2, GPD2, GPP1 and GPP2, and
wherein said cells further comprise one or more nucleic acid
sequences encoding an acetyl-Coenzyme A synthetase activity (EC
6.2.1.1) and one or more nucleic acid sequences encoding NAD+dependent alcohol dehydrogenase activity (EC 1.1.1.1).
(Dkt. #1-1 at 40 (67:12-37).) Claim 1 of the PTC application, on the other hand provided
simply:
Recombinant yeast cell, in particular a transgenic yeast cell, the cell
comprising one or more recombinant, in particular heterologous,
nucleic acid sequences encoding an NAD+-dependent acetylating
acetaldehyde dehydrogenase (EC 1.2.1.10) activity, said cell either
lacking enzymatic activity needed for the NADH-dependent glycerol
synthesis or the cell having a reduced enzymatic activity with respect
to the NADH-dependent glycerol synthesis compared to its
corresponding wild-type yeast cell.
(Dkt. #192-12 at 49 (47:1-7).)
38
alternative available to it. While the fact that Firestart is subject to a separate patent is
not unduly confusing to the jury by itself, Firestart is simply not relevant enough to
overcome the risks of jury confusion and undue delay regarding disputes tangential to the
principle issues actually before the jury.
Accordingly, Lallemand’s MIL No. 11 is
GRANTED.
L. MIL No. 12: Preclude DSM from Referring to Third-Parties’ Enhanced Yeast
Products.
Next, Lallemand seeks to exclude evidence of “genetically-modified yeast products
made, used, sold, or offered for sale by third parties” because neither side “argued that
these products constitute potential non-infringing alternatives” and “their existence is
otherwise not relevant.” (Dkt. #188 at 60.)24 Lallemand argues that referencing this
evidence, particularly “the alleged proprietary or patented nature of such products,” would
be unfairly prejudicial because DSM’s damages expert will testify that there were
“competing yeast products on the market” when the infringement began, “but that these
products were not ‘available’ to Lallemand because they are proprietary to third parties.”
(Id. at 60-61.) This hardly seems good grounds to exclude evidence of the marketplace in
which Lallemand competes. In particular, Lallemand’s argument that it would be unfairly
prejudicial because such testimony could “suggest to the jury that Lallemand is competing
unfairly,” ignores that the introduction of this evidence would only come in during the
damages phase of the trial, after the jury would have already found exactly that.
Lallemand, however, “reserves the right to rely on evidence of past negotiations between DuPont
and DSM concerning a potential license to the ’998 patent.” (Dkt. #188 at 60 n.25.)
24
39
Lallemand’s contention that because it will not rely on third-party technology as
noninfringing alternatives, Dr. David’s testimony is irrelevant similarly misses the mark:
Lallemand does not get to arbitrarily define what market information may be important
during a theoretical royalty negotiation. Finally, Lallemand argues that David’s opinion
that “few other companies” used “patented techniques or proprietary enzymes” is
unsupported, but it will be up to the jury whether company publications are sufficient to
support David’s observation about the marketplace.
Accordingly, Lallemand’s MIL No. 12 is DENIED, except that evidence of other
competitor’s introduction of enhanced yeast products may only come in during the
damages phase of trial.
M. MIL No. 13: Trifurcate Trial, Separating Willful Infringement from Damages.
Lallemand requests that instead of bifurcating trial into two phases (liability and
damages), the court create a third and separate phase for the jury to hear evidence of willful
infringement (if necessary). (Dkt. #188 at 63.) Specifically, Lallemand contends that
“any potential efficiency gained from t[r]ying willfulness together with other issues is
outweighed by the possibility of prejudice to Lallemand.” (Id.) Recognizing that isolating
issues for separate adjudication rests in the discretion of the court, Lallemand argues that
infringement and willfulness “‘present different underlying issues and, at least generally
speaking, require different proof,’” adding that the court has previously separated
willfulness from liability. (Id. (quoting Robert Bosch, LLC v. Pylon Mfg. Corp., 719 F.3d
1305, 1317 (Fed. Cir. 2013) and citing Ameritox, Ltd. v. Millennium Health, LLC, No. 13cv-832-wmc, 2015 WL 1520821, at *2 (W.D. Wis. Apr. 3, 2015)).)
40
DSM responds that Lallemand’s request is unsupported and unnecessary. (Dkt.
#212 at 16.) Pointing out that this court typically includes willfulness in the damages
phase, DSM would distinguish Ameritox based on its reliance on In re Seagate Technology,
LLC, 497 F.3d 1360 (Fed. Cir. 2007), which was subsequently overruled by the U.S.
Supreme Court. See Halo Elecs., Inc. v. Pulse Elecs., Inc., 136 S. Ct. 1923, 1928 (2016).
Regardless, separating out willfulness falls squarely within the discretion of the
court.
Typically, willfulness is considered by the jury at the same time as damages.
Lallemand neither distinguishes this case from those typically brought before this court,
nor identifies any specific form of prejudice that would make trifurcation necessary, or
even appropriate, here.
Nor does it identify any evidence that would relate only to
willfulness that would not have been introduced during the liability or damages phases
anyway. Accordingly, Lallemand’s MIL No. 13 is DENIED without prejudice.
N. MIL No. 14: Exclude Evidence or Argument Regarding Lallemand’s Lack of
Advice of Counsel before Launching the Accused products.
Perhaps an exception to the discussion above is Lallemand’s contention that DSM
“intends to assert that Lallemand ‘did not obtain a freedom-to-operate opinion . . . prior
to launch of the Accused Products’” and that that assertion is prejudicial and irrelevant,
and should otherwise be excluded under 35 U.S.C. § 298. (Dkt. #188 at 65 (quoting dkt.
#191-17 at 13).) Lallemand adds that this type of argument is particularly prejudicial
because Lallemand launched the Accused Products before the ’998 patent was issued. (Id.)
Predictably, DSM opposes this motion as well. (See dkt. #212 at 18-19.) First,
DSM contends that § 298 offers no protection because Lallemand obtained a letter from
41
counsel after DSM sued and designated the letter’s author as a trial witness. Second, DSM
argues that Lallemand began selling YP3 two years after the ’998 patent was issued, as well
as a year after DSM alerted Lallemand about the alleged infringement. (Id. at 18.) DSM
acknowledges that Lallemand began selling TransFerm Yield+ to non-POET customers
before the ’998 patent was issued, but the launch of specific TransFerm Yield+ for POET
customers occurred afterwards, in mid-2015. (Id. at 19.) Finally, again relying on the
February 2011 agenda, DSM argues Lallemand knew about the technology disclosed in
the ’998 patent as early as 2011 and recognized its relevance. (Id. at 19.)
An infringer’s failure to seek the advice of counsel cannot be used to prove willful
infringement. See 35 U.S.C. § 298. Specifically,
[t]he failure of an infringer to obtain the advice of counsel with
respect to any allegedly infringed patent, or the failure of the
infringer to present such advice to the court or jury, may not
be used to prove that the accused infringer willfully infringed
the patent or that the infringer intended to induce
infringement of the patent.
Id. As this court has previously explained, however, “the protection granted by 35 U.S.C.
§ 298 dissolves in the event defendants ‘open the door’ by attempting to refute a claim of
willful infringement by implying that they relied on the advice of counsel.” Ultratec, Inc. v.
Sorenson Communs., Inc., No. 13-cv-346-bbc, 2014 WL 4976596, at *2 (W.D. Wis. Oct. 3,
2014). Merely naming counsel as a trial witness does not by itself constitute such an
exception, particularly since Lallemand represents in its reply that it “will not seek to
introduce evidence and otherwise will not suggest to the jury that it sought advice of
counsel with respect to the ’998 patent at any time before it launched the Accused
Products.” (Dkt. #225-1 at 16.) Accordingly, this motion is DENIED unless Lallemand
42
opens the door at trial.
O. MIL No. 15: Strike References to Lallemand’s Counsel in Professor Alper’s
2018 Report
Finally, Lallemand asks the court to strike portions of Alper’s substitute report that
rely on or refer to statements of Lallemand’s counsel for the purpose of “avoid[ing]
implicating [Lallemand’s] counsel as a fact witness,” adding that statements or argument
by counsel are not evidence. (Dkt. #188 at 66.)25 Since expert reports are inadmissible
hearsay and DSM agrees, any reference to Mr. Cahill’s statements made during the
telephonic hearing” are inadmissible, this motion is DENIED AS MOOT.26
ORDER
IT IS ORDERED that:
1) DSM’s motions in limine (dkt. #185) are GRANTED IN PART, DENIED IN
PART, AND RESERVED IN PART as set forth above.
During the court’s telephonic motion hearing, Lallemand explained that Mr. Argyros “said that
the defendants didn’t engage in a process to design around the patent . . . . They engaged in a
process of building a number of alternatives and testing them for the purpose of seeing which ones
had the best performance.” (Dkt. #188 at 66 (quoting dkt. #139 at 13:19-23).) Professor Alper
then cited these statements to support his testimony that (1) “Lallemand has admittedly not
genuinely pursued any strategies to design around the ’998 patent to date” and (2) “Lallemand
admits that, to date, it has not taken any steps to implement a design-around.” (Id. at 67 (quoting
dkt. #146 ¶¶ 220, 257).)
25
26
DSM does assert that “the substance of Dr. Alper’s opinions . . . is undisputed and supported by
the testimony of a Lallemand Employee, Aaron Argyros,” so that Alper should still be able to opine
that Lallemand failed to design around the ’998 patent. (Dkt. #212 at 19.) Rule 26(a)(2)(B)
requires an expert report to contain “a complete statement of all opinions the witness will express
and the basis and reasons for them.” Fed. R. Civ. P. 26(a)(2)(B)(i). Because the only evidence
Alper cites in his report as support for the identified opinions is the hearing transcript, these two
“opinions” would appear unsupported in any event. The court will address this concern further in
its opinion and order on Lallemand’s motion to exclude two types of Dr. Alper’s opinions (dkt.
#190).
43
2) Lallemand’s motions in limine (dkt. #188) are GRANTED IN PART AND
DENIED IN PART as set forth above.
3) Lallemand’s motion for leave to file reply brief (dkt. #225) is GRANTED.
Entered this 24th day of April, 2018.
