MEMORANDUM OPINION AND ORDER
AMY J. ST. EVE, District Court Judge:
Plaintiff The Medicines Company’s (“TMC”) has moved to preclude the testimony and
opinions of Dr. Nancy J. Linck, offered by Defendant Mylan Inc., Mylan Pharmaceuticals Inc.,
and Bioniche Pharma USA, LLC (collectively, “Mylan”) pursuant to Federal Rule of Evidence
702 and Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579, 113 S. Ct. 2786, 125 L.
Ed. 2d 469 (1993). For the reasons discussed below, the Court grants in part and denies in part
TMC’s motion.
BACKGROUND
This action arises out of a patent infringement case involving U.S. Patent No. 7,582,727
(R. 358-1, “the ‘727 Patent”) The ‘727 patent “relates to a compounding process for preparing a
pharmaceutical batch(es) of a drug product or a pharmaceutical formulation(s) comprising
bivalirudin as an active ingredient.” (Id., ‘727 patent at col. 2 ll. 29-32) Bivalirudin is the active
ingredient in TMC’s Angiomax® drug product, an injectable anticoagulant used to prevent blood
clotting during coronary procedures. TMC has sold Angiomax® since 2001. Before expiration
of the patents-in-suit, Mylan submitted Abbreviated New Drug Application (“ANDA”) No.
202471 to the U.S. Food and Drug Administration (“FDA”), seeking approval to engage in the
commercial manufacture, use, sale, offer for sale, and/or importation of a generic equivalent to
Angiomax®. TMC claimed that Mylan’s ANDA No. 202471 infringes several claims of the
patents-in-suit. The Court granted in part and denied in part Defendants’ motion for summary
judgment of non-infringement, invalidity, and willful infringement. 1 In defense of the remaining
infringement claims, Mylan has asserted that TMC committed inequitable conduct during the
prosecution of the ‘727 patent.
On February 8, 2013, Mylan served TMC with the expert report of Dr. Nancy J. Linck.
Mylan seeks to offer Dr. Linck’s testimony to support its claims that the co-inventors of the ‘727
patent, Drs. Gary Musso and Gopal Krishna, committed inequitable conduct during the
prosecution of the ‘727 patent. Dr. Linck is a patent attorney who also holds a Ph.D. in inorganic
chemistry, and has more than twenty years of experience in patent law and with the United States
Patent and Trademark Office’s (“Patent Office”) practices and procedures. Dr. Linck was
formerly the Solicitor of Patents and Trademarks at the Patent Office. She also was an
Administrative Patent Judge, where she evaluated the decisions of Patent Office examiners. Dr.
Linck opined on Mylan’s theory of inequitable conduct based on her knowledge and expertise in
the field, the ‘727 file history, and the record of the case.
Specifically, Dr. Linck opined that certain material information was known to Drs.
Musso and Gopal Krishna during the prosecution of the ‘727 patent, and that the material
information was either withheld from the Patent Office or misrepresented to the patent examiner.
1
The Court granted Defendants’ motion for summary judgment of non-infringement of the other
patent-in-suit (U.S. Patent No. 7,598,343), and also granted Defendants’ motion for summary
judgment on Plaintiffs’ claim for willful infringement. (R. 309, Mem, Op, & Order.)
2
Linck concluded that an examiner would not have issued the claims of the ‘727 patent had the
information been disclosed or had misrepresentations not been made. (R. 324-1 ¶¶ 114-34.) Dr.
Linck also identified certain record evidence from which the Court could draw an inference of
intent to deceive the Patent Office. (Id. ¶¶ 135-49.)
LEGAL STANDARD FOR DAUBERT MOTIONS
“The admissibility of expert testimony is governed by Federal Rule of Evidence 702 and
the Supreme Court’s opinion in Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 113 S. Ct.
2786, 125 L. Ed. 2d 469 (1993).” See also Apple Inc. v. Motorola, Inc., __ F.3d __, 2014 WL
1646435 at *18 (Fed. Cir. Apr. 25, 2014); Lewis v. Citgo Petroleum Corp., 561 F.3d 698, 705
(7th Cir. 2009). Rule 702 provides, in the relevant part, that “[i]f scientific, technical or other
specialized knowledge will assist the trier of fact[,] . . . a witness qualified as an expert by
knowledge, skill, experience, training or education, may testify thereto in the form of an
opinion. . . .” Id. See also Happel v. Walmart Stores, Inc., 602 F.3d 820, 824 (7th Cir. 2010).
Under the expert-testimony framework, courts perform the gatekeeping function of
determining whether the expert testimony is both relevant and reliable prior to its admission at
trial. See id.; Power Integrations, Inc. v. Fairchild Semiconductor Intern., Inc., 711 F.3d 1348,
1373 (Fed. Cir. 2013); United States v. Pansier, 576 F.3d 726, 737 (7th Cir. 2009) (“To
determine reliability, the court should consider the proposed expert’s full range of experience
and training, as well as the methodology used to arrive [at] a particular conclusion.”). In doing
so, courts “make the following inquiries before admitting expert testimony: first, the expert must
be qualified as an expert by knowledge, skill, experience, training, or education; second, the
proposed expert must assist the trier of fact in determining a relevant fact at issue in the case;
third, the expert’s testimony must be based on sufficient facts or data and reliable principles and
3
methods; and fourth, the expert must have reliably applied the principles and methods to the facts
of the case.” Lees v. Carthage College, 714 F.3d 516, 521-22 (7th Cir. 2013); see also Stollings
v. Ryobi Tech., Inc., 725 F.3d 753, 765 (7th Cir. 2013); Power Integrations, 711 F.3d at 1373;
Pansier, 576 F.3d at 737. In evaluating these issues, “[a] judge must be cautious not to overstep
its gatekeeping role and weigh facts, evaluate the correctness of conclusions, impose its own
preferred methodology, or judge credibility, including the credibility of one expert over another.
These tasks are solely reserved for the fact finder.” Apple, 2014 WL 1646435 at * 19.
It is clear that “genuine expertise may be based on experience or training.” United States
v. Conn, 297 F.3d 548, 556 (7th Cir. 2002) (quoting Tyus v. Urban Search Mgmt., 102 F.3d 256,
263 (7th Cir. 1996)). “[W]hile extensive academic and practical expertise in an area is certainly
sufficient to qualify a potential witness as an expert, Rule 702 specifically contemplates the
admission of testimony by experts whose knowledge is based on experience.” Trustees of
Chicago Painters & Decorators Pension, Health & Welfare, & Deferred Sav. Plan Tr. Funds v.
Royal Int’l Drywall & Decorating, Inc., 493 F.3d 782, 787-88 (7th Cir. 2007) (citations and
quotations omitted). As such, courts “consider a proposed expert’s full range of practical
experience, as well as academic or technical training, when determining whether that expert is
qualified to render an opinion in a given area.” Id. (quoting Smith v. Ford Motor Co., 215 F.3d
713, 718 (7th Cir. 2000)).
In addition, as the Seventh Circuit teaches:
Where the gatekeeper and the factfinder are one and the same – that is, the judge
– the need to make such decisions prior to hearing testimony is lessened. See
United States v. Brown, 415 F.3d 1257, 1268-69 (11th Cir. 2005). That is not to
say that the scientific reliability requirement is lessened in such situations; the
point is only that the court can hear the evidence and make its reliability
determination during, rather than in advance of, trial. Thus, where the factfinder
and the gatekeeper are the same, the court does not err in admitting the evidence
4
subject to the ability later to exclude it or disregard it if it turns out not to meet the
standard of reliability established by Rule 702.
In re Salem, 465 F.3d 767, 777 (7th Cir. 2006); see also Metavante Corp. v. Emigrant Sav. Bank,
619 F.3d 748, 760 (7th Cir. 2010) (observing that “the court in a bench trial need not make
reliability determinations before evidence is presented” because “the usual concerns of the rule –
keeping unreliable expert testimony from the jury – are not present in such a setting”); Brown,
415 F.3d at 1269 (“There is less need for the gatekeeper to keep the gate when the gatekeeper is
keeping the gate only for himself.”). Under this approach, where the judge will serve as the trier
of fact at trial, the Court may choose to (1) allow the presentation of borderline testimony, (2)
subject the testimony to the rigors of cross-examination, and (3) decide later whether the
testimony is entitled to some consideration or whether it should be excluded as irrelevant,
unreliable, or both. Nevertheless, at some point before disposition of the case, the court “must
provide more than just conclusory statements of admissibility or inadmissibility to show that it
adequately performed its gatekeeping function.” Metavante Corp., 619 F.3d at 760.
ANALYSIS
TMC seeks to exclude the entire testimony of Dr. Nancy J. Linck, or in the alternative,
limit several of Dr. Linck’s opinions on certain issues relating to the prosecution of the ‘727
patent. TMC asks the Court to preclude Dr. Linck’s testimony alleging that she is not a qualified
expert to testify on Mylan’s inequitable conduct theories, and that Dr. Linck’s testimony will not
aid the trier of fact. Alternatively, TMC argues that the Court should preclude Dr. Linck from
offering several legal and technical opinions, particularly in the area of inequitable conduct.
Specifically, TMC argues that the Court should strike Dr. Linck’s opinions and testimony
regarding: (1) the intent or state of mind of the inventors; (2) the interpretation of patent law and
court decisions; (3) conclusions of law; (4) the intent or state of mind of the Patent Office
5
Examiner; (5) mistakes made by the Patent Office; and (6) technical matters outside Dr. Linck’s
expertise. The Court will address each argument in turn.
I.
Dr. Nancy J. Linck
Mylan expert Dr. Nancy Linck is an attorney who has more than twenty years of
experience in patent law and Patent Office practices and procedures. Dr. Linck is the former
Solicitor of Patents and Trademarks, serving as general counsel and the highest-ranking lawyer
at the Patent Office. She also is a former Administrative Patent Judge who was responsible for
reviewing determinations of Patent Office examiners, including denials of patent applications.
Additionally, she has testified before Congress, the Federal Trade Commission, and the
Department of Justice regarding improvements to the U.S. patent system.
Dr. Linck received a Juris Doctor degree in 1984 from Johns Hopkins University, has
been a partner at two law firms, and in-house counsel at a chemical company and a
pharmaceutical company. Dr. Linck is an Adjunct Professor of Law at Georgetown University
Law Center, a position she has held since 1998, and was previously an Adjunct Professor at
George Washington School of Law. Dr. Linck holds a B.S. in chemistry from the University of
California, Berkeley, and an M.S. and Ph.D. in inorganic chemistry from University of
California, San Diego. Based on her significant legal and technical qualifications, Mylan offered
Dr. Linck’s opinions in support of its claim that TMC’s inventors committed inequitable conduct
during the prosecution of the ‘727 patent.
II.
Dr. Linck is Qualified to Testify as an Expert in This Case
TMC first moves the Court to preclude Dr. Linck’s testimony in its entirety because she is
not qualified to opine on the examination of the ‘727 patent conducted by the Patent Office, or to
provide opinions supporting Mylan’s position that the co-inventors committed inequitable
6
conduct. TMC asserts that Dr. Linck is not a qualified expert capable of testifying about
inequitable conduct because she has “never been a patent examiner.” (R. 320 at 4.)
The Court finds TMC’s argument regarding the qualifications of Dr. Linck unavailing.
Dr. Linck has more than twenty years of patent law experience including serving as the Solicitor
of Patents and Trademarks, the highest-ranking attorney in the Patent Office. Further, Dr. Linck
served as an Administrative Patent Judge responsible for reviewing the determinations of Patent
Office examiners. While Dr. Linck has never been a Patent Office examiner, she actually
reviewed the decisions of Patent Office examiners, making her well-qualified to opine on issues
arising in the patent prosecution process. Additionally, Dr. Linck is well-regarded in the patent
field, having testified before Congress, the Federal Trade Commission, and the Department of
Justice regarding improvements to the U.S. patent system. She is an adjunct law professor, and a
patent attorney, giving even more weight to her expertise in the field of patent law. One court
explicitly found Dr. Linck “undoubtedly qualified to testify as an expert on patent application
issues relating to inequitable conduct” solely based on her work at the Patent Office. See Wyeth
v. Apotex Inc., No. 08-22308-CIV, 2009 WL 8626786, at *2-4 (S.D. Fla. Oct. 6, 2009). The
Court finds Dr. Linck’s extensive, impressive qualifications more than sufficient to allow her to
opine on Mylan’s theories of inequitable conduct and other prosecution issues relating to the
‘727 patent.
TMC also asks the Court to preclude Dr. Linck’s testimony in its entirety because it would
“fail to assist the trier of fact.” (R. 320 at 4.) To support its position TMC cites District of
Delaware cases where the courts precluded legal experts from testifying at trial. See Cancer
Research Tech. Ltd. v. Barr Labs., Inc., Civ. No. 07-457 (D. Del. Mar. 4, 2009) (striking any
legal expert from testifying at trial including Dr. Linck’s inequitable-conduct opinions); Brigham
7
& Women’s Hosp. Inc. v. Teva Pharms. USA, Inc., Civ. A. No. 08-464, 2010 WL 3907490, at *2
(D. Del. Sept. 21, 2010) (barring parties from explaining patent prosecution histories through
expert testimony). These cases are not binding on the Court.
TMC also relies on National Diamond, where the Court excluded a patent expert’s
testimony regarding inequitable conduct. Nat'l Diamond v. Flanders Diamond, 00 C 6402, 2003
WL 24890292, at *1 (N.D. Ill. Apr. 30, 2003). National Diamond, however, involved a jury trial
rather than a bench trial where the expert sought to “ simplify” the issues in the area of
inequitable conduct for purposes of the jurors’ understanding. Id. As the Court noted in
National Diamond, the parties did not need to present such issues to the jury since it was not a
jury issue. Here, preclusion of Dr. Linck’s testimony is unnecessary because the Court is the
trier of fact, with the capability of curtailing her opinions if necessary at trial. See, e.g., Bone
Care Int’l LLC v. Pentech Pharm., Inc., No. 08 C 1083, 2010 WL 3928598, at *2-3 (N.D. Ill.
Oct. 1, 2010).
Additionally, courts within this District and others routinely allow qualified patent experts
to testify on inequitable conduct. Id. at *9 (patent law experts may testify on “the history of the
‘488 application’s prosecution that may be probative to the issue of intent [to deceive]” and on
the “materiality element of inequitable conduct”); Se-Kure Controls, Inc. v. Vanguard Prods.
Grp., Inc., No. 02 C 3767, 2008 WL 169054, at *3-4 (N.D. Ill. Jan. 17, 2008) (patent law expert
may testify about general patent procedures, operations and functions of the PTO, materiality of
relevant prior art, and factual context for why plaintiff’s behavior may have been inequitable).
See also Worldwide Home Products, Inc. v. Time Inc., 11 CIV. 3633 LTS MHD, 2013 WL
5477480, at *5 (S.D.N.Y. Sept. 30, 2013).
Because Dr. Linck is qualified by her experience and expertise to testify as a patent law
8
expert regarding the application and issuance of the ‘727 patent relating to Mylan’s inequitable
conduct claims, the Court denies TMC’s request to exclude her opinions and testimony in their
entirety. TMC can challenge Dr. Linck’s opinions regarding inequitable conduct allegedly
committed by the inventors of the ‘727 patent through its own witnesses and through rigorous
cross-examination during trial.
III.
Inequitable Conduct
An accused infringer asserting a claim for inequitable conduct “must show by clear and
convincing evidence that the patent applicant (1) misrepresented or omitted information material
to patentability, and (2) did so with specific intent to mislead or deceive the PTO.” Network
Signatures, Inc. v. State Farm Mut. Auto. Ins. Co., 731 F.3d 1239, 1242 (Fed. Cir. 2013) (quoting
In re Rosuvastatin Calcium Patent Litig., 703 F.3d 511, 519 (Fed. Cir. 2012)). “Materiality and
intent must be separately established.” Id. The intent to deceive element of an inequitable
conduct claim is a question of fact. Bone Care, 2010 WL 3928598, at *9 (citing Upjohn Co. v.
MOVA Pharm. Corp., 225 F.3d 1306, 1312 (Fed. Cir. 2000)). Thus, there are two elements of a
claim of inequitable conduct: first, the materiality of misrepresentations, misinformation, or
withheld information; and second, the intent to deceive. Honeywell Int'l Inc. v. Universal
Avionics Sys. Corp., 488 F.3d 982, 999 (Fed. Cir. 2007); see also Star Scientific, Inc. v. R.J.
Reynolds Tobacco Co., 537 F.3d 1357, 1365 (Fed. Cir. 2008).
IV.
Dr. Linck’s Opinions Regarding Patent Law and Inequitable Conduct
A.
Dr. Linck May Testify on Facts Relating to the Intent to Deceive Element of
the Inequitable Conduct Claim
TMC argues the Court should preclude Dr. Linck’s opinions regarding the state of mind
of each of the inventors, and her opinions on their intent to deceive the Patent Office regarding
the application and examination of the ‘727 patent. (R. 320 at 7.) Specifically, TMC asserts that
9
Dr. Linck is not qualified to testify on the co-inventors’ intent to deceive because she does not
possess any special qualifications that would allow her to discern the co-inventors’ thoughts.
(Id.)
Patent experts may not testify that they know the patentee’s intent to hide or lie about
certain information during the patent prosecution process “because they are not mind-readers.”
Bone Care, 2010 WL 3928598, at *9. Additionally, patent experts may not “plumb the
inventor’s and attorney’s minds and discern whether they ‘lacked candor’ or had actual intent to
deceive during the patent prosecution process.” Id. (citing Se-Kure Controls, 2008 WL 169054,
at *2). Mylan concedes that Dr. Linck cannot testify as to whether the inventors actually had a
specific intent to deceive the Patent Office, but asserts that Dr. Linck may identify certain facts
from the file history and record to support an inference that the applicants acted with intent to
deceive. (R. 377 at 6.) See Bone Care, 2010 WL 3928598, at *9 (Attorney expert’s Patent
Office experience “qualified [him] to offer evidence regarding the history of the ‘488
application’s prosecution [as it] may be probative to the issue of intent [to deceive the Patent
Office].”). The Court agrees. This aspect of TMC’s motion is granted only to preclude Dr.
Linck’s opinions regarding the inventors’ intent to deceive.
B.
The Legal Standards Upon Which Dr. Linck Bases Her Opinions
Next, TMC asks the Court to preclude several of Dr. Linck’s opinions “explaining or
interpreting patent law and court decisions.” (R. 320 at 2.) TMC asserts that such opinions will
not assist the Court in interpreting the issue of inequitable conduct in the application and
issuance of the ‘727 patent. Dr. Linck’s opinions include certain Patent Office procedures and
practices such as: the grounds which an examiner can reject a patent application (R. 324-1 ¶¶ 3138.); the grounds under which a reference would be prior art (R. 324-3 ¶¶ 16.); the duty of
10
candor an applicant has during prosecution (R. 324-1 ¶¶ 41-60.); and the standard that examiners
apply in determining whether a reference is material. (Id.)
Dr. Linck may offer opinions regarding the Patent Office’s practices and procedures
based on her prior experience in the Patent Office and her extensive experience in patent law and
procedure. See Bone Care, 2010 WL 3928598, at *14 (holding that patent expert’s proposed
testimony admissible relating to patent application process, operations and functions of the PTO,
and the criteria which examiners evaluate in assessing patentability). Indeed, courts allow patent
law experts to testify on “general procedures involved in the patent application process.”
Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1360 (Fed. Cir. 2008). She may
also opine on whether a certain criteria is material to a Patent Office examiner. See Bone Care,
2010 WL 3928598, at *14 (admitting discussion of “criteria to which examiners look in
assessing patentability (including obviousness, priority, etc.”)); Liquid Dynamics Corp. v.
Vaughan Co., Inc., 01 C 6934, 2004 WL 2260626, at *7 (N.D. Ill. Oct. 1, 2004) (finding
admissible patent law expert discussion of materiality); Worldwide Home Products, 2013 WL
5477480, at *5.
TMC also challenges Dr. Linck’s statements regarding the legal standards upon which
she relies to formulate her opinions as improper legal opinions. Dr. Linck may testify regarding
the legal standards upon which she relies for her opinions. See, e.g., A.E. ex rel. Evans v. Indep.
Sch. Dist. No. 25, of Adair Cnty., Okl., 936 F.2d 472, 476 (10th Cir. 1991) (“An expert may []
refer to the law in expressing his or her opinion.”) Citing to statutes, legal definitions, and cases
is acceptable when a legal expert is explaining the bases of how she arrived at her opinions.
CHECK See Voter Verified, Inc. v. Premier Election Solutions, Inc., 6:09-CV-1968-ORL-19,
2011 WL 87306, at *4 (M.D. Fla. Jan. 11, 2011) (district court refused to strike an expert’s
11
opinion when he properly cited to statute and standards for evaluating obviousness announced in
case law, and applied the principles to his obviousness analysis). She may not, however, give
general testimony interpreting patent law.
Finally, the trial in this case is a bench trial. The Court is fully aware of the law of
inequitable conduct in the context of patent applications and examinations. The Court, as the
trier of fact in this case, is free to disregard or curtail the testimony provided by Dr. Linck. See,
e.g., Bone Care, 2010 WL 3928598, at *2-3; Armament Sys., 2007 WL 1267877, *1.
C.
Some of Dr. Linck’s Opinions Are Improper Legal Conclusions
TMC next asks the Court to preclude certain legal conclusions found in Dr. Linck’s
expert report. (R. 320 at 9-11.) Specifically, TMC points out three examples in Dr. Linck’s
opening report as legal conclusions concerning conception 2, inventorship 3, and inequitable
conduct 4. (Id.) TMC claims each of these opinions contains legal conclusions, which the Court
may address at the end of the trial. In the Seventh Circuit, “expert testimony that contains a legal
conclusion that determines the outcome of a case is inadmissible.” Sommerfield v. City of
Chicago, 254 F.R.D. 317, 330 (N.D. Ill. 2008) (citing RLJCS Enterprises, Inc. v. Prof’l Ben.
Trust Multiple Emp’r Welfare Ben. Plan & Trust, 487 F.3d 494, 498 (7th Cir. 2007). “Rule 704
was not intended to allow experts to offer opinions embodying legal conclusions.” Bausch &
Lomb, Inc. v. Alcon Labs., Inc., 79 F.Supp.2d 252, 255 (W.D.N.Y. 2000) (quoting United States
v. Scop, 846 F.2d 135, 139 (2d Cir.1988)); Se-Kure Controls, Inc. v. Diam USA, Inc., 06 C 4857,
2
“In my opinion, the single most reasonable conclusion to be drawn from this evidence is that
the inventors and possibly others acted with a deliberate intent to deceive the USPTO and obtain
allowance of patent claims to which they are not entitled.” (R. 324-1 ¶ 146.)
3
“In any case, the relevant point is that Ben Venue (“BVL”) staff who are not named as
inventors undeniably contributed to the alleged ‘conceptions’ of the claimed invention.” (R.
324-3 ¶ 15.)
4
“Had this information been disclosed to Examiner Ha, in my opinion she would have rejected
the application claims as invalid under 35 U.S.C. § 102(f).” (R. 324-1 ¶ 130.)
12
2009 WL 77463, at *2 (N.D. Ill. Jan. 9, 2009) (concluding that proposed testimony of a patent
expert on whether the patent at issue is enforceable, whether the patentee committed inequitable
conduct, or the level of intent behind any alleged failures to disclose prior art was all
inadmissible).
In opposition, Mylan asserts that Dr. Linck’s opinions are admissible on two grounds.
First, Mylan argues that expert testimony on legal conclusions is properly precluded in jury trials
for fear it will usurp the court’s role, but such testimony is acceptable in bench trials as long as
the court remains the trier of fact and draws its own legal conclusions. See Bone Care, 2010 WL
3928598, at *3; Se-Kure Controls, 2009 WL 77463, at *2; Del Mar Avionics, Inc. v. Quinton
Instrument Co., 836 F.2d 1320, 1325 (Fed. Cir. 1987). Second, Mylan contends that Dr. Linck’s
testimony does not contain legal conclusions or speculation, stating that there is a “difference
between stating a legal conclusion and providing concrete information against which to measure
abstract legal concepts.” United States v. Blount, 502 F.3d 674, 680 (7th Cir. 2007). “The
former is prohibited; the latter is not.” Bone Care, 2010 WL 3928598, at *14. Mylan argues that
Dr. Linck’s challenged opinions are tying an abstract legal concept to the objective facts on the
record. (R. 377 at 10.) Id. (citing Se-Kure Controls, 2009 WL 77463, *2) (allowing “factual
context” for why prosecution behavior was inequitable, including “materiality of the relevant
prior art”); Worldwide Home Products, 2013 WL 5477480, at *5 (“He has based his opinions on
the factual record . . . , His opinions are relevant to the adequacy of Plaintiff's disclosures to . . . ,
which is a question of mixed law and fact.”).
The opinions identified by TMC and cited above go beyond proper opinion testimony.
Instead, they are improper legal conclusions and speculation. TMC’s motion on this issue is
therefore granted. denied.
13
D.
Dr. Linck May Provide Opinions Regarding What Facts Would Have Been
Material to the Patent Office Examiner
TMC also moves to exclude statements by Dr. Linck regarding her opinion of what the
Patent Office Examiner would have done or thought had TMC given her different information:
•
“Moreover, Examiner Ha would not have allowed the patents to issue
had she known that the allegedly ‘new’ process used to make bivalirudin
resembled the ‘old’ process more closely than admitted by TMC in its
patent application.” (R. 324-1 ¶ 128.) (emphasis added);
•
“It is my opinion that Examiner Ha would not have allowed the claims
of the patents-in-suit had she know that multiple techniques described
as ‘efficient mixing’ in the patents were already in the prior art, or had
been suggested by persons not named as inventors in the applications.
( Id.) (emphasis added);
•
“It is my opinion that instead [Examiner Ha] would have rejected
the claims as obvious over the prior art compounding process.”
( Id.) (emphasis added)
•
“Finally, Examiner Ha would not have allowed the patents to issue
had she known that the true inventors had not been named.” ( Id. ¶
129.) (emphasis added);
•
“In my opinion, had the USPTO been informed that the claimed
invention was in fact derived from concepts provided to the named
inventors by a third party under no common duty of assignment, the
USPTO would not have allowed the claims to issue.” (R. 324-3 ¶ 19.)
(emphasis added)
These statements by Dr. Linck do more than merely reference the Patent Office examiner;
they speculate as to what she would have done or thought had she been given different
information. See, e.g., Se-Kure Controls, 2009 WL77463, at *2 (curtailing the expert’s proposed
testimony and explaining that experts are not “mind-reader[s]”); Applied Materials, Inc. v.
Advanced Semiconductor Materials Am., Inc., C 92-20643 RMW, 1995 WL 261407, at *2 (N.D.
Cal. Apr. 25, 1995) (“The court grants Applied’s motion precluding Nusbaum from testifying
about what the examiner would have done if Nusbaum had been the examiner, or if the examiner
14
had different information. The evidence would be irrelevant speculation . . . .”). Thus, the Court
grants TMC’s motion to preclude Dr. Linck from opining on what the Patent Office Examiner
would have done or thought had she been given different information.
Additionally, the parties agree that courts permit experts to opine on facts that may be
relevant to an inequitable conduct defense. 5 While Dr. Linck is precluded from opining on what
the patent examiner would have done or thought had she been presented other information, Dr.
Linck may opine as to what she believes would have been material to the patent examiner, based
on her expertise in patent law. Experts are permitted to opine on materiality and make relevant
testimony. CBOE v. ISE, No. 07 C 623, ECF No. 701 at 3-4 (N.D. Ill. March 7, 2013) (citing
Sundance, 550 F.3d at 1363 n.5) (allowing relevant expert testimony from expert who did not
have “ordinary skill in the field of computer programming,” the relevant art). Thus, the Court
denies this aspect of Plaintiff’s motion to preclude Dr. Linck’s testimony, and she may opine on
the materiality to the Patent Examiner of the undisclosed prior art’s potential effect on the ‘727
patent application process.
E.
The Presumption of Validity
Next, TMC argues that the testimony Dr. Linck intends to provide regarding “the general
likelihood of the Patent Office to make mistakes … would undermine the statutory presumption
of validity of issued patents under 35 U.S.C. § 282.” (R. 320 at 11.) Specifically, TMC
references Paragraph 20 of Dr. Linck’s opening expert report:
From time to time, patents are granted that do not meet one or
more of the statutory requirements for patentability. In other words,
5
See Bone Care, 2010 WL 3928598, at *14 (“Mr. Sofocleous may provide factual context that
goes to the underlying contentions of inequitable conduct . . . , but he may not speculate or offer
his subjective conclusions on those contentions. Similarly, Mr. Sofocleous may offer any extant
facts regarding acts or omissions in the applications giving rise to the [patent in suit], but he may
not speculate as to the intent of the inventors or attorneys.”) (citations omitted).
15
the USPTO makes mistakes. The courts may declare such patents
invalid. Also, under some circumstances, ordinarily involving
misconduct by the patentee(s) before the USPTO, the courts may
declare patents unenforceable based on inequitable conduct.
(R. 324-1 ¶ 20.) Courts have precluded patent experts from offering “generalized testimony
about potential memory problems of examiners or other non-case specific testimony
‘insinuating that the PTO does not do its job properly.’” Bone Care, 2010 WL 3928598, at *15
(citations omitted).
Mylan argues that the Court is capable of filtering between passing references to
“mistakes” in the Patent Office made by Dr. Linck and the presumption of validity of a patent,
and that the Court still may nonetheless find a patent invalid or unenforceable. This argument
fails to address TMC’s assertion that generalized testimony about “other non-case specific
testimony ‘insinuating that the PTO does not do its job properly’” is not permitted. See Bausch
& Lomb, 79 F. Supp. 2d at 255-56 (citing Applied Materials, 1995 WL 261407, at *3). The
Court agrees with TMC. Dr. Linck may present testimony to the extent that she has a basis for
opining on actual defects in the patent application process or inequitable conduct relating to the
′727 patent. The Court will not, however, permit Dr. Linck to offer generalized, non-case
specific testimony insinuating that the Patent Office makes mistakes or does not do its job
properly.
F.
Dr. Linck Does Not Opine on “Technical” Matters Outside of Her Expertise
Finally, TMC argues that the Court should preclude Dr. Linck from opining on “technical
opinions” outside of her field of expertise. (R. 320 at 12.) Specifically, TMC alleges that Dr.
Linck improperly analyzes and compares the original and improved Angiomax® drug product,
improperly opines on the materiality of technical information, and improperly interprets the
patent in suit. (Id.) TMC further alleges that Dr. Linck, as an attorney, lacks the required
16
technical qualifications to opine on such technical issues. (Id.)
1.
Dr. Linck Is Qualified to Provide Technical Opinions Related to Her
Experience and Expertise in the Pharmaceutical Industry
TMC first argues that Dr. Linck is not qualified to provide technical opinions, “including
opinions regarding: (i) scientific matters; (ii) the materiality of technical information; and (iii)
the interpretation of the patent in suit.” (R. 320 at 13.) TMC claims that Dr. Linck is not a
person of ordinary skill in the art (“POSITA”) under Mylan’s definition 6 because “[Dr. Linck]
lacks experience in formulating peptide drugs.” (Id.) Using Mylan’s definition, TMC asks the
Court to preclude Dr. Linck from providing technical opinions and from offering testimony as to
whether scientific and technical information would have been material during prosecution of the
patents in suit, because she is not a POSITA or an expert on technical aspects of the ‘727 patent.
Bone Care, 2010 WL 3928598, at *13 (precluding the expert from testifying on the “the
scientific significance and materiality of prior art references . . .” because the expert lacked
qualifications to opine on “scientific or technological facts . . .”). TMC also asks the Court to
preclude Dr. Linck from interpreting the patents in suit. “Unless a patent lawyer is also a
qualified technical expert, his testimony on these kinds of technical issues is improper and thus
inadmissible.” Sundance, 550 F.3d at 1362 (holding that the district court abused its discretion
in allowing defendant’s patent-law expert to testify on how the disclosed invention operates
because he lacked relevant expertise in the pertinent art). The Court rejects TMC’s arguments.
Dr. Linck has a sufficient technical background to offer these opinions. She has several
years of work experience in both the chemical and pharmaceutical industries, both technicallyrelated and legally-related. Indeed, based on Dr. Linck’s combination of legal experience and
6
According to Mylan, a POSITA would “understand the use of active pharmaceutical
ingredients and excipients to formulate a drug product, including use of peptides as API . . . .”
(R. 324-7 ¶ 106.)
17
years of experience working with drug formulations, one court permitted her to opine on both the
legal and technical aspects of a pharmaceutical patent. See Wyeth, 2009 WL 8626786, at *3-4
(“Dr. Linck is not being offered simply as a patent lawyer opining as one who was actually
skilled in the art, but instead that Dr. Linck could be considered a person skilled in the art given
her legal expertise coupled with her practical work experience in the pharmaceutical industry.”)
Furthermore, Dr. Linck meets TMC’s definition of a POSITA – someone who possesses a B.S.
in chemistry and a “few years” of pharmaceutical work experience. (R. 361-2 ¶ 27.)
Given her experience, Dr. Linck is qualified to rely on her own independent review of the
‘727 patent, and opine on (i) scientific matters; (ii) the materiality of technical information; and
(iii) the interpretation of the ‘727 patent. TMC is free to vigorously cross examine Dr. Linck
regarding her qualifications to testify on both technical and non-technical.
2.
Dr. Linck May Rely on the Opinions of Other Experts Combined
TMC further argues that Dr. Linck is unqualified to combine her own technical opinions
with opinions of Mylan’s technical experts. TMC challenges her reliance on the opinions of
other Mylan experts. TMC’s challenge fails.
Dr. Linck has relied on the technical analyses of several other Mylan experts in rendering
her opinions, including Dr. Ian McKeague, Dr. David Auslander, and Dr. Fred Regnier. (R. 3243 ¶¶ 8, 11, 13-14, 18, 30, 32, 33, 36, 38, 39.) Mylan contends that Dr. Linck formed her patent
prosecution opinions relying on the opinions of these several experts. As the Federal Circuit
recently noted, “[e]xperts routinely rely upon other experts hired by the party they represent for
expertise outside of their field.” Apple Inc. v. Motorola, Inc., __ F.3d __, 2014 WL 1646435, 25
(Fed. Cir. Apr. 25, 2014). Indeed, experts need not base their opinions on first-hand knowledge
or research actually conducted by the expert herself. See Daubert, 509 U.S. at 592; Walker v.
18
Soo Line R.R., 208 F.3d 581, 588 (7th Cir. 2000) (“courts frequently have pointed to an expert's
reliance on the reports of others as an indication that their testimony is reliable”). Dr. Linck
properly relied on these other expert opinions. TMC’s motion to exclude Dr. Linck’s opinions
formed in reliance on other experts and her own technical expertise is denied.
CONCLUSION
For the reasons discussed in detail above, the Court grants in part and denies in part
TMC’s motion to preclude certain testimony of Mylan’s expert, Dr. Nancy J. Linck.
