OPINION (Preliminary Inj. & Motion to Dismiss). Signed by Judge Kevin McNulty on 9/20/16. (DD, )
UNITED STATES DISTRICT COURT
FOR THE DISTRICT OF NEW JERSEY
FRESENIUS KABI USA, LLC,
No. 15-cv-3654 (KM)(MAH)
Plaintiff,
FERA PHARMACEUTICALS, LLC, et al.,
OPINION
(Preliminary Injunction and
Motion to Dismiss)
Defendants.
KEVIN MCNULTY U.S.D.J.:
The plaintiff, Fresenius Kabi USA, LLC, brings two motions against, two
of the defendants in this suit, Fera Pharmaceuticals, LLC and Oakwood
Laboratories, LLC (collectively, “Fera”)’: 1) a motion to dismiss Fera’s
inequitable conduct counterclaims (ECF No. 89), and 2) a motion for
preliminary injunction (ECF NO. 187). Fresenius’s underlying suit again Fera
is for patent infringement. The patents-in-suit are Patent Nos. 9,006,289 (“the
‘289 patent”), 9,168,238 (“the ‘238 patent”), and 9,168,239 (“the ‘239 patent”).
All three describe formulations of levothyroxine, a hormone produced by the
thyroid. These patents claim a form of lyophilized (i.e. freeze-dried)
levothyroxine that can be reconstituted and injected into patients who lack a
properly functioning thyroid. (P1. Opening 1) Claims 1, 2, 4, 14, 15, and 16 of
the ‘289 patent are the subject of this preliminary injunction motion. (Prel. Inj.
1 At the parties’ request, this patent infringement
suit was consolidated for
pretrial purposes with one against InnoPharma, Inc. and InnoPharma Licensing, LLC
(collectively, “InnoPharma”), originally filed under the docket number 15—3655. (See
ECF No. 79) Presenius has not asked for a preliminary injunction against
InnoPharma. A third suit, docket number 15—3853, was originally consolidated with
these two, but those defendants settled with Fresenius after the opening briefs were
filed. (See ECF No. 120)

On July 25, 2016, I convened a hearing on the motion of Fresenius for a
preliminary injunction. To shorten the hearing, I directed the parties that I
would accept affidavits in lieu of direct testimony, and offered both sides the
opportunity to cross-examine. Both sides declined the opportunity, and opted
to rely on their papers. As a result, any facts related herein rest on the
persuasiveness, or not, of written representations; there was no opportunity to
assess credibility. This opinion is structured primarily as a discussion of the
motion for a preliminary injunction. The arguments on the motion to dismiss
the inequitable conduct claims are discussed in the context of the likelihood of
success on the merits.
I.
BACKGROUND
A grandfathered version of a levothyroxine injectable, not approved by
the FDA, has been available in the United States since 1969. (Prel. Inj. Opp. 4
(citing Def. Ex. 253-6 at 6280)) In the early 2000s, APP Pharmaceuticals
marketed that grandfathered version. On December 18, 2006, APP received a
warning letter from the United States Food and Drug Administration notifying
it that an NDA would be required. (Meachum Deci.
¶
14) In 2008, Fresenius
acquired APP. In 2010, Fresenius filed an NDA on a “more stable formulation of
its Levothyroxine product.” That NDA was approved on June 24, 2011.
In many cases, a 30-month stay operates to give the parties and the
court breathing space to decide issues of patent validity and infringement. The parties
agree that, for various reasons of timing, the 30-month stay does not apply here. See
21 U.S.C. § 355(j)(5)(B)(iii).
3
3
(Meachum Deci.
15—17; see also Prel. Inj. Opp. 4) Based on that new, FDAapproved formulation, Fresenius applied for and eventually received the ‘289,
¶J
‘238, and ‘239 patents.
Fresenius’s newly patented formulations contain levothyroxirie, a buffer,
and a specific amount of a bulking agent called mannitol. The innovation at the
heart of Fresenius’s patents is a claim that a lower amount of mannitol, as
compared with the grandfathered versions, unexpectedly increased the stability
of the formulation. (Prel. Inj. Br. 5)
Fera and InnoPharma filed Abbreviated New Drug Applications (“ANDA”)
that sought approval to commercially market generic versions of Fresenius’s
patented levothyroxine injections. Fresenius, claiming that these would infringe
its patents, seeks to enjoin them from doing so.
II.
ANALYSIS
Whether a preliminary injunction is warranted depends on four factors:
(1) whether the moving party is likely to succeed on the merits; (2) whether the
moving party is likely to suffer irreparable harm in the absence of preliminary
relief; (3) whether granting preliminary relief will result in even greater harm to
the nonmoving party; and (4) whether an injunction is in the public interest.

(D.N.J. 2015).
A.
Likelihood of Success on the Merits
Fera’s challenge is directed primarily to the first factor: Fresenius’s
likelihood of success on the merits of its claim of patent infringement.
1.
Federal Circuit standard
The United States Court of Appeals for the Federal Circuit, which has
appellate jurisdiction over patent cases, applies the law of the regional circuits
when reviewing preliminary injunction decisions. Aevoe Corp. v. AE Tech Co.,
727 F.3d 1375, 1381 (Fed. Cir. 2013) (citing Abbott Labs. v. Sandoz, Inc., 544
F.3d 1341, 1367 (Fed. Cir. 2008)). However, it applies Federal Circuit law to
substantive matters of patent infringement, including the first of the four
preliminary injunction factors: the likelihood of success in establishing patent
infringement. Revision Military, Inc. v. Balboa Mfg. Co., 700 F.3d 524, 526 (Fed.
Cir. 2012). And Fed. R. Civ. p. 65, of course, applies regardless.
In Arnazon.com, Inc. v. Bamesandnoble.com, Inc., the Federal Circuit
announced, or reaffirmed, the standard by which district courts hearing patent
cases should review the preliminary injunction factor of likelihood of success
on the merits: If the alleged infringer “raises a substantial question concerning
either infringement or validity, i.e., asserts an infringement or invalidity defense
that the patentee cannot prove lacks substantial merit, the preliminary
injunction should not issue.” 239 F.3d 1343, 1350—5 1 (Fed. Cir. 2001) (internal
quotation marks omitted) (citing Genentech, Inc. v. Novo Norclisk A/ S, 108 F. 3d
1361, 1364 (Fed. Cir. 1997)). The Amazon court further explained that, rather
than the “clear and convincing” standard for proving patent invalidity at trial,
“[v]ulnerability is the issue at the preliminary injunction stage.” Id. at 1359.
Amazon’s standard may have been cast into doubt, however, by the
subsequent Supreme Court case of eBay Inc. v. MercExchange, L.L.C., 547 U.S.
388, 391, 126 S. Ct. 1837 (2006). In eBay, the Supreme Court reviewed a
5
Federal Circuit post-trial decision to apply a “general rule that courts will issue
permanent injunctions against patent infringement absent exceptional
circumstances.” 547 U.S. at 391 (quoting MercExchange, LLC v. eBay, Inc., 401
F.3d 1323, 1339 (Fed. Cir. 2005)). The Court reemphasized that “the decision
whether to grant or deny injunctive relief rests within the equitable discretion
of the district courts, and that such discretion must be exercised consistent
with traditional principles of equity, in patent disputes no less than in other
cases governed by such standards.” Id. at 394. In short, the Supreme Court
seemed to reemphasize the primacy of the traditional four-factor analysis for
injunctive relief, albeit in the context of a permanent, not preliminary,
injunction. Id. at 391.
Doubts have thus arisen as to the continuing viability of the Federal
Circuit’s holding that, for preliminary injunctive relief, the “substantial
question” standard requires only a showing of patent “vulnerability.” Thus, in
the aftermath of eBay, Judge Newman dissented in two Federal Circuit
decisions that vacated preliminary injunctions in patent cases. Both times, she
objected to the majorities’ holdings that a “substantial question” of invalidity
suffices to defeat a motion for a preliminary injunction. Erico, 516 F.3d at
1359—60; An.drx Pharm., 452 F.3d at 1349—52. The fullest statement of Judge
Newman’s views is contained in her opinion in Sandoz, supra. There, although
she wrote for the majority, the relevant section of her opinion was not joined by
her companion in the majority or by the dissenting Judge Gajarsa. Judge
Newman thoroughly reviewed the preliminary injunction standards of all the
other circuits and argued that “all refer to the likelihood of the eventual
outcome, not whether a substantial question has been raised.” 544 F.3d at
1365. In Judge Newman’s view, certain panels of the Federal Circuit had
departed from the proper standard when they looked only to the alleged
infringer’s raising of a “substantial question” as to the patent’s validity. That
approach, in her view, undermined the proper application of the “likelihood of
success on the merits” standard. Id. at 1364.
6
The following year, both Judge Newman and Judge Gajarsa joined an
opinion by Judge Plager that attempted to reconcile the “substantial question”
standard with the traditional equitable factors. See Titan Tire Corp. v. Case New
Holland, Inc., 566 F.3d 1372 (Fed. Cir. 2009). Titan Tire started from the basic
principle that “[i]n assessing whether the patentee is entitled to the injunction,
the court views the matter in light of the burdens and presumptions that will
inhere at trial.” Id. at 1376 (citing Gonzales v. 0 Centro Espirita Beneficente
Uniao do Vegetal, 546 U.S. 418, 429, 126 S. Ct. 1211(2006)). Issued patents
maintain a statutory presumption of validity at trial, and the defense of
invalidity must be proven by clear and convincing evidence. Id.; see 35 U.S.C.
§
282. On a motion for preliminary injunction, Titan Tire held, the patent likewise
enjoys a presumption of validity. Should its validity be challenged, however, the
patentee has the burden to respond and show a likelihood of success on the
merits. Id. at 1377.
The Titan Tire court then analyzed New England Braiding Co. v. A. W.
Chesterton Co., 970 F.2d 878 (Fed. Cir. 1992), which was cited in the
Genentech case from which the Amazon panel drew the “substantial question”
standard. In New England Braiding, the court wrote:
The district court cannot be held to have erred in deciding that the
patentee failed to make a sufficient showing of likelihood of
success required to support a preliminary injunction where the
evidence presented in support of invalidity raises a substantial
question, although the defense may not be entirely fleshed out....
While it is not the patentee’s burden to prove validity, the patentee
must show that the alleged infringer’s defense lacks substantial
merit.
970 F.2d at 883 (emphasis added). Viewing this paragraph as a whole, Titan
Tire concluded that a trial court should consider both the evidence of invalidity
and the patentee’s rebuttal evidence. 566 F.3d at 1377—78 (citing Genentech,
108 F.3d at 1364 (“In other words, if Novo raises a ‘substantial question’
concerning validity
...
(i.e., asserts a defense that Genentech cannot show
‘lacks substantial merit’) the preliminary injunction should not issue”).
7
Attempting to synthesize the case law, Titan Tire stated that denial of a
preliminary injunction entails a conclusion “that the patentee is unlikely to
succeed on the merits of the validity issue because the patentee is unable to
establish that the alleged infringer’s invalidity defense lacks substantial merit.”
Id. at 1378. That is a substantial bar, said Titan Tire, but it does not
prematurely require that the opponent of relief meet its ultimate burden of
proving invalidity by clear and convincing evidence. Rather, at the preliminary
injunction stage, the court must “assess the potential of a ‘clear and
convincing’ showing [of invalidity] in the future, but in terms of what is ‘more
likely than not’ presently.” Id. at 1380.
Judges of the Federal Circuit—albeit in nonprecedential or nonmajority
decisions—have questioned whether the Titan synthesis has truly reconciled
the Federal Circuit preliminary injunction standard with the traditional
equitable factors, in keeping with eBay, supra. For example, Kimberly-Clark
Worldwide, Inc. v. First Quality Baby Products, LLC, 431 F. App’x 884, 887 (Fed.
Cir. 2011), an unpublished decision, continued to cite the “vulnerability”
language from Amazon, to the evident consternation of Judge Newman: “[T]he
attempted reconciliation in Titan Tire appears to have failed, for this panel
provides no qualification for its position that if validity is reasonably
questioned, the injunction will be denied.” Kimberly-Clark Worldwide, Inc. v.
First Quality Baby Products, LLC, 660 F.3d 1293, 1299 (Fed. Cir. 2011)
(Newman, J., dissenting from denial of rehearing, joined by Judges O’Malley
and Reyna). Judge O’Malley added that “[djistrict courts across the country
4
have struggled with our precedent in this area, concluding in large measure
that, whatever their views of the merits of a particular preliminary injunction
As a district judge, Judge O’MaIley had subscribed to a position similar to that
of Judge Newman. See Avery Dennison Corp. v. Alien Tech. Corp., 626 F. Supp. 2d 693,
699 (N.D. Ohio 2009); Erico Int’l Corp. v. Doe’s Mktg., Inc., Civ. No. 05—2924, 2007 WL
108450, at *9 (N.D. Ohio Jan. 9, 2007). His championing of the perplexed district
judge is thus rooted in personal experience.
8
request, this court’s precedent virtually mandates denial of all such motions.”
Id. at 1301 (O’Malley, J., dissenting).
Unpublished Federal Circuit opinions dating from after the KimberlyClark rehearing denial have cited Titan Tire. See Hoffmann—La Roche Inc. v.
Apotex Inc., 496 F. App’x 46, 50—5 1 (Fed. Cir. 2012) (“Regarding the likelihood
of success on the merits, it was Roche’s burden to show, in light of the burdens
and presumptions that will inure at trial, that it will likely prove infringement
and that it will likely withstand any invalidity challenge to the patent.”); Warner
Chilcott Labs. Ireland Ltd. v. Mylan Pharm. Inc., 451 F. App’x 935, 938—39 (Fed.
Cir. 2011) (“the trial court first must weigh the evidence both for and against
validity that is available at this preliminary stage in the proceedings”).
5
Other post-Titan Federal Circuit panel decisions, however, both reported
and unreported, seem to apply the legacy Amazon standard in reviewing
preliminary injunction decisions. See, e.g., LfeScan Scotland, Ltd. v. Shasta
Techs., LLC, 734 F.3d 1361, 1366 (Fed. Cir. 2013); Sciele Pharma Inc. v. Lupin
Ltd., 684 F.3d 1253, 1261 (Fed. Cir. 2012); Kimberly-Clark Worldwide, Inc. V.
First Quality Baby Products, LLC, 431 F. App’x 884, 886—87 (Fed. Cir. 2011);
Altana Pharma, 566 F.3d at 1005—06; Erico Int’l Corp. v. Vutec Corp., 516 F.3d
1350, 1356 (Fed. Cir. 2008); Abbott Labs. v. AndrxPhann., Inc., 452 F.3d 1331,
1335 (Fed. Cir. 2006). It is not clear, however, that the standard made any
difference in those cases. In LfeScan, for example, the Court held that the
defendant had “established a patent exhaustion defense as a matter of law.”
The other reported case applying the “substantial question” standard, Sciele,
does not cite or discuss the relevance of Titan.
In this district, some recent decisions have followed the guidance of Titan
Tire. See, e.g., Roxane Labs., Inc. v. Camber Pharm. Inc., Civ No. 14—4042, 2014
WL 3854140, at *2 (D.N.J. Aug. 6, 2014), affd, 596 F. App’x 922 (Fed. Cir.
Judge O’Malley wrote Warner, and Judges Newman and O’Malley sat on the
unanimous panel in Hoffman.
9
2015) (“To obtain a preliminary injunction, Roxane must show that it will likely
prove infringement, and that it will likely withstand challenges, if any, to the
validity of the patent.”). See also e.g., Otsuka Pharm. Co. v. Torrent Pharm. Ltd.,
Inc., 99 F. Supp. 3d 461, 475, 497, 499 (D.N.J. 2015) (citing vulnerability
standard, but also seemingly adopting the Titan Tire burden shifting analysis,
concluding that “these Defendants
have established a substantial question
...
of invalidity
and [the plaintifq has not shown that this question of invalidity
lacks substantial merit.”).. Others, however, have cited the “vulnerability”
...
language from Amazon without qualification. See, e.g., Yowie N. Am., Inc. v.
Candy Treasure, LLC, Civ No. 14—1409, 2014 WL 1871910, at *4 (D.N.J. May 8,
2014).
So what to do? Even if Titan Tire had, as a doctrinal matter, laid the
issue to rest, there remains the problem of conflicting panel decisions. The
Federal Circuit, like many, “has the rule that in the event of conflict between
panels the earlier holding prevails until overturned en banc.” Sandoz, 544 F.3d
at 1371 (citing Newell Companies v. Kenney Mfg. Corp., 864 F.2d 757, 765 (Fed.
Cir. 1988)); accord Texas Am. Oil Corp. v. U.S. Dep’t of Energy, 44 F.3d 1557,
1561 (Fed. Cir. 1995) (“This court applies the rule that earlier decisions prevail
unless overruled by the court en banc, or by other controlling authority such
as intervening statutory change or Supreme Court decision.”) Thus Titan Tire, a
panel decision, could not of its own authority overturn the standard
announced in the earlier panel decision of Amazon. That rule, of course, is
subject to the still more basic principles that intervening precedent of the U.S.
Supreme Court must in all events control, and that Fed. R. Civ. P. 65 binds
every district court, whether in a patent or non-patent case.
eBay is not so clearly on point as to simply overrule earlier Federal
Circuit preliminary injunction cases, such as Amazon. If that were so, the issue
would be an easy one. The eBay decision involved a remedial question:
whether, after a trial in which infringement was found, the court should apply
a general presumption that a permanent injunction should issue. The
10
preliminary injunction context poses problems of its own, involving the
probability that infringement will be found, the allocation of risk in the interim,
and the desirability of maintaining the status quo.
By the same token, however, Titan Tire does not merely overturn prior
panel decisions, which, under the Court’s operating procedures, it was not
empowered to do. Titan Tire does not purport to overthrow, but rather to
reconcile, the strands of the case law. I believe it succeeds in doing so—placing
the burden on the defendant to raise a substantial issue, in which case the
patentee must demonstrate the likelihood that it will succeed in meeting it
ultimate burden of persuasion by clear and convincing evidence.
As a district judge, I am ill-equipped to enforce the internal operating
procedures of the Federal Circuit, 6 or to decide which of its precedents to give
priority. I tend to agree that the traditional preliminary injunction factors
should be paramount, and that the Supreme Court has so signaled in eBay.
Under that approach, where a substantial issue has been raised, the likelihood
of success factor would require a court to weigh both sides’ evidence and
contentions, and to assess the plaintiff’s likelihood of prevailing at trial. And
that factor, of course, will be informed by the substance and procedures of
patent law. I will therefore attempt to remain faithful to Federal Circuit case
law and apply the Titan synthesis. As noted herein, however, I do not believe
the standard would influence the result as to most issues, but I have noted
where I believe it might.
2.
Infringement
Fresenius argues that Fera’s product, if marketed, will infringe
independent claims 1 and 14 and dependent claims 2, 4, 15, and 16 of the ‘289
patent. (Prel. Inj. Br. § III.A. 1) Fresenius’s expert submits that Fera’s proposed
6
I will not venture into the meta-question of how to reconcile a
disagreement between panels as to whether there is a conifict between panel
decisions.
11
generic formulations fall within the limitations of each of those claims. Fera’s
only challenge to those infringement allegation per se is that the patent
requires a buffer. A buffer, argues Fera, should be defined as a liquid, whereas
Fera’s formulation is a lyophilized solid with no liquid components. (Prel. Inj.
Opp.
§ lI.A) In the accompanying claim construction opinion, I have construed
the term “buffer” in a manner that is fatal to this argument. Consequently, I
find that Fera has not raised a substantial issue, and that Fresenius is likely to
succeed on this issue.
3.
Patent validity
Fera next argues that Fresertius is unlikely to succeed on the merits
because its patents are invalid. In support, Fera asserts the doctrines of double
patenting; anticipation and the on-sale bar; obviousness; and inequitable
conduct/unclean hands. I consider them in order.
i.
Double patenting
The chief vice of double patenting is the potential for an unwarranted
extension of the patent term. An inventor cannot, by re-patenting the same
invention, extend the monopoly beyond the original term. Fera argues that the
‘289 patent is invalid because it is “virtually the same” as, or an obvious
variant on, as the earlier-expiring ‘239 patent. (Prel. Inj. Opp. 2.B)
§
The ‘289 patent was issued on April 14, 2015; the ‘238 and ‘239 patents
were issued a few weeks later, on October 27, 2015. As it happens, however,
the ‘289 patent received a patent term adjustment from the PTO under 35
U.S.C. § 154(b) that extended its anticipated expiration date to October 3,
2032. Thus the ‘238 and ‘239 patents, though issued later, expire five weeks
earlier, on August 29, 2032. These facts appear to be undisputed.
A section 154(b) extension is granted based on the USPTO’s own delays
in processing. 35 U.S.C. § 154(b).
12
In Gilead Scis., Inc. u. Natco Pharma Ltd., the Federal Circuit held that an
earlier expiring patent, even if issued later, would “qualify as an obviousnesstype double patenting reference for a later-expiring patent.” 753 F.3d 1208,
1217 (Fed. Cir. 2014), cert. denied, 135 S. Ct. 1530 (2015). Albeit under
circumstances different from this case, Gileaci proclaimed categorically that the
“patent expiration dates [] should control” because that approach best
comports with the “bedrock principle of our patent system that when a patent
expires, the public is free to use not only the same invention claimed in the
expired patent but also obvious or patentably indistinct modifications of that
invention.” Id. at 1214-15. That holding receives further support from Abbvie
Inc. v. Mathilda & Terence Kennedy Inst. of Rheumatology Trust, which
specifically mentioned patents that are “filed at the same time
...
[yet have
different patent terms due to examination delays at the PTO.” 764 F.3d 1366,
1373 (Fed. Cir. 2014) (citing 35 U.S.C. § 154(b)).

Gilead reasoned that its holding would “preserve[] the ability of inventors
to use a terminal disclaimer of later-expiring patents to create one expiration
date.” 753 F.3d at 1216. By a “terminal disclaimer,” Gilead meant a patentee’s
voluntary relinquishment of the portion of the second-expiring patent’s term
that extends beyond that of the first-expiring patent. Such disclaimers, said
Gilead, “effectively overcome any objection to improper term extension.” Id.
Here, Fresenius notified the Court that it has filed for a terminal
disclaimer that, if accepted by the PTO, would shorten the extended expiration
of the’289 patent and bring it into conformity with those of the ‘238 and ‘239
Gilead confined the inquiry to the expiration date because the Uruguay Round
Agreements Act (“URAA”) “changed the term for a U.S. patent from seventeen years
from the patent issue date to twenty years from the earliest effective filing date.”
Gilead, 753 F.3d at 1211 (citing Pub.L. No. 103—465, § 532(a), 108 Stat. 4809, 4983—
85 (1994)). Should there be a circumstance where a terminal disclaimer is unavailable,
the holding that expiration dates control seems potentially draconian if it could
invalidate a patent whose expiration date is later because of a patent term adjustment
where the delay is solely the fault of the PTO.

13
patents. (See ECF. No. 291) In essence, Fresenius has agreed to give up the
last five weeks of patent protection in August—October 2032. That concession, I
find, removes any substantial basis for the double patenting objection. And
because the extension resulted, not from any action of Fresenius but because
of delay in the PTO’s examination process, there is no inference of sharp
practice.
While the PTO has not yet accepted the terminal disclaimer, it seems
likely that they will do so, and Fera has not suggested otherwise. (See ECF No.
292) Thus, Fera is unable to raise a substantial question of invalidity on this
issue, and Fresenius has demonstrated a likelihood of success on the merits as
to double patenting.
ii.
Anticipation and the on-sale bar
Fera argues that claims 1 and 2 of the ‘289 patent are anticipated by the
grandfathered products and thus unpatentable under the on-sale bar. “To
establish an on-sale bar, it must be shown that the device sold fully anticipated
the claimed invention or would have rendered the claimed invention obvious by
its addition to the prior art.” Allen Eng’g Corp. v. Bartell Indus., Inc., 299 F.3d
1336, 1352 (Fed. Cir. 2002) (internal quotation marks and citations omitted).
A prior art reference can only anticipate a claim if it discloses all
the claimed limitations arranged or combined in the same way as
in the claim. However, a reference can anticipate a claim even if it
d[oes] not expressly spell out all the limitations arranged or
combined as in the claim, if a person of skill in the art, reading the
reference, would at once envisage the claimed arrangement or
combination.
Kennametal, Inc. u. Ingersoll Cutting Tool Co., 780 F.3d 1376, 1381 (Fed. Cir.
2015) (internal quotation marks and citations omitted). In short, the
grandfathered drug must literally duplicate the current formulation, or be so
close as to be an obvious variant.
Specifically, Fera argues that the grandfathered levothyroxine
formulations, which contain 500 pg of levothyroxine sodium per vial and either
10 or 15 mg of mannitol (Bedford; Nentwich 357), anticipate claims 1 and 2 of
14
the ‘289 patent, which describe 100 or 200 ig of levothyroxine and 2-4 or 3 mg
of mannitol. (‘289 Patent claims 1—2) Fera’s argument is that a simple
segregation of, say, 1/5 or 1/2 of the grandfathered product would produce a
product indistinguishable from that described by the ‘289 patent. (Prel. Inj.
Opp.
§ II.C.2)
The preparations of both Bedford’s and Nentwich’s grandfathered
products belie this argument. Each describes a vial containing either 200 or
500 ig but with the amount of mannitol remaining at 10 or 15 mg, irrespective
of the total amount of the lyophilized product. (Bedford; Nentwich 357) Thus,
these formulations are consistent with Fresenius’s claim that, prior to its
discovery, the conventional wisdom was that more mannitol was better. (Prel.
Inj. Br. 5)
[U]nless a reference discloses within the four corners of the
document not only all of the limitations claimed but also all of the
limitations arranged or combined in the same way as recited in the
claim, it cannot be said to prove prior invention of the thing
claimed and, thus, cannot anticipate under 35 U.S.C. § 102.
Net MoneyI Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008).
Nor is it apparent from these grandfathered formulations that a person of
ordinary skill in the art would realize that stability would be enhanced by a
reduction in the amount of mannitol when creating a lower dosage version.
The grandfathered formulations may contain the same or similar
ingredients, but they keep the mannitol proportion consistent for different sized
formulations. They therefore do not arrange the proportions of the ingredients
in a way that is identical to, or an obvious variant on, the formulation in the
‘289 patent. Under the “substantial issue” standard, this is a closer question.
Nevertheless, in light of the considerations discussed here and in the following
subsection, Fresenius has demonstrated a likelihood of success.
iii.
Obviousness/on sale bar
Relatedly, Fera argues that portioning the grandfathered formulations
can demonstrate the obviousness of the ‘289 patent. They claim that
Fresenius’s formulation with less mannitol would be an obvious variant of the
15
grandfathered Bedford or Nentwich formulation when creating a 100 pg
composition (Prel. Inj.
Opp. § II.C.3)
To simplify, Fresenius’s patent teaches
that the amount of mannitol, contrary to expectation, should remain at
between 2 and 4 pg, irrespective of the sized of the dose. But look, says Fera.
Take Nentwich’s 500 pg formulation, which contains 15 pg of mannitol, and
divide it by five. The result is a 100 pg formulation, which contains 3 pg of
mannitol, a formulation that falls within the scope of the ‘289 patent. This,
however, misses the point of the claimed innovation. The innovation, says
9
Fresenius, is that a composition of any size can be stabilized by keeping the
level of mannitol low—i.e., by not multiplying or dividing the amount of
mannitol to keep it in a fixed proportion to the amount of the formulation as a
whole. Fera presents no substantial argument as to why a person of ordinary
skill in the art would act otherwise and challenge what Fresenius presents as
the conventional wisdom: the larger the dose, the larger the amount of
mannitol.
“If a person of ordinary skill in the art can implement a predictable
variation, and would see the benefit of doing so,
§ 103 likely bars its
patentability.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 401, 127 S. Ct. 1727
(2007). Fera does not successfully suggest that the ‘289 patent is a predictable
variation, nor has Fera argued why, prior to the discovery upon which the
patent rests, a person of ordinary skill in the art would see the benefit of
reducing the amount of mannitol.
Further, even if the obviousness showing had been stronger, Fera does
not bring evidence to dispute the unexpected properties allegedly discovered by
Fresenius. “Objective evidence of nonobviousness can include
...
unexpected
properties of the claimed invention. These objective considerations can protect
Fresenjus points out that the Nentwich formulations were not shown to
contain a phosphate buffer or phosphate salt, either. That circumstance renders their
status as prior art even more problematic.
9
16
against the prejudice of hindsight bias, which often overlooks that the genius of
invention is often a combination of known elements which in hindsight seems
preordained. Power Integrations, Inc. v. Fairchild Semiconductor Int’l, Inc., 711
F.3d 1348, 1368 (Fed. Cir. 2013).
I observe in passing that the grandfathered formulation remains
unpatented. At oral argument counsel pointed out, without contradiction, that
anyone (subject to regulatory approvals, of course) is free to market the
grandfathered formulation. The Fresenius formulation, now patented and being
marketed, is an incremental improvement on that formulation, which has a
longer shelf life. Clearly this is not a scientific breakthrough, but the record is
uncontradicted that it is a previously-unanticipated improvement. Fera’s “slice
and dice” argument does not raise a substantial question as to the legitimacy of
the innovation. Fresenius is likely to prevail on this issue.
iv.
Inequitable conduct
Fera also asserts the doctrine of inequitable conduct. “Inequitable
conduct is an equitable defense to patent infringement that, if proved, bars
enforcement of a patent. This judge-made doctrine evolved from a trio of
Supreme Court cases that applied the doctrine of unclean hands to dismiss
patent cases involving egregious misconduct.” Therasense, Inc. v. Becton,
Dickinson & Co., 649 F.3d 1276, 1285 (Fed. Cir. 2011). The inequitable
conduct claim here is that Fresenius “concealed but-for material information
showing that the prior art lyophilized compositions were as stable as the
purported invention.” Prel. Inj. Opp at 1.
Many of Fera’s inequitable conduct claims, asserted as counterclaims,
are the subject of a motion to dismiss.’° In their preliminary injunction briefs,
the parties incorporate by reference their briefs from that motion to dismiss.
Some of the arguments are new and have not been pleaded. (Prel. Inj.
24—25; Prel. Inj. Reply 10)
10
17
Opp
(Prel. Inj. Opp. 22; Prel. Inj. Reply 10 n.4) The discussion here is therefore
relevant to both the motion to dismiss and the preliminary injunction motion.
In Therasense, Inc. v. Becton, Dickinson. & Co., the Federal Circuit, sitting
en banc, set out the contours of the inequitable conduct doctrine:
To prevail on a claim of inequitable conduct, the accused infringer
must prove that the patentee acted with the specific intent to
deceive the PTO. A finding that the misrepresentation or omission
amounts to gross negligence or negligence under a “should have
known” standard does not satisfy this intent requirement. In a
case involving nondisclosure of information, clear and convincing
evidence must show that the applicant made a deliberate decision
to withhold a known material reference. In other words, the
accused infringer must prove by clear and convincing evidence that
the applicant knew of the reference, knew that it was material, and
made a deliberate decision to withhold it.
649 F.3d 1276, 1290 (Fed. Cir. 2011) (internal quotation marks and citations
omitted). Intent and materiality are the elements of an inequitable conduct
claim and independent evidence of each is required to prove the defense. Id. (“A
court must weigh the evidence of intent to deceive independent of its analysis
of materiality. Proving that the applicant knew of a reference, should have
known of its materiality, and decided not to submit it to the PTO does not prove
specific intent to deceive.”).
Therasense also set forth the test for proving the intent element:
Because direct evidence of deceptive intent is rare, a district court
may infer intent from indirect and circumstantial evidence.
However, to meet the clear and convincing evidence standard, the
specific intent to deceive must be the single most reasonable
inference able to be drawn from the evidence. Indeed, the evidence
must be sufficient to require a finding of deceitful intent in the light
of all the circumstances. Hence, when there are multiple
reasonable inferences that may be drawn, intent to deceive cannot
be found.
Id. at 1290—91.
Therasense also refined the Federal Circuit’s standard for materiality:
This court holds that, as a general matter, the materiality required
to establish inequitable conduct is but-for materiality. When an
applicant fails to disclose prior art to the PTO, that prior art is but
for material if the PTO would not have allowed a claim had it been
18
aware of the undisclosed prior art. Hence, in assessing the
materiality of a withheld reference, the court must determine
whether the PTO would have allowed the claim if it had been aware
of the undisclosed reference. In making this patentability
determination, the court should apply the preponderance of the
evidence standard and give claims their broadest reasonable
construction.
Id. 1291—92.
I briefly address and deny the motion to dismiss, which is analyzed on a
lower standard than, and is logically prior to, the preliminary injunction.
The parties dispute whether the “single most reasonable inference” test of
intent applies on a motion to dismiss. Prior to Therasense, the Federal Circuit
set out in Exergen Corp. v. Wal-Mart Stores, Inc. the requisites for pleading
inequitable conduct:
[T]o plead the “circumstances” of inequitable conduct with the
requisite “particularity” under Rule 9(b), the pleading must identif’
the specific who, what, when, where, and how of the material
misrepresentation or omission committed before the PTO.
Moreover, although “knowledge” and “intent” may be averred
generally, a pleading of inequitable conduct under Rule 9(b) must
include sufficient allegations of underlying facts from which a
court may reasonably infer that a specific individual (1) knew of
the withheld material information or of the falsity of the material
misrepresentation, and (2) withheld or misrepresented this
information with a specific intent to deceive the PTO.
575 F.3d 1312, 1328—29 (Fed. Cir. 2009). “Exergen involved a motion to amend
after a full trial on the merits.” Jersey Asparagus Farms, Inc. v. Rutgers Univ.,
803 F. Supp. 2d 295, 308 (D.N.J. 2011). But, “courts in this District have held
that Exergen applies to the pleading stage.” Mycone Dental Supply Co. v.
Creative Nail Design, Inc., No. CIV.A. 11-4380 JBS, 2013 WL 3216145, at *5
(D.N.J. June 24, 2013) (collecting cases). Further, the Federal Circuit itself
continued to cite Exergen in a motion to dismiss case decided after The rasense:
A charge of inequitable conduct based on a failure to disclose will
survive a motion to dismiss only if the plaintiffs complaint recites
facts from which the court may reasonably infer that a specific
individual both knew of invalidating information that was withheld
from the PTO and withheld that information with a specific intent
to deceive the PTO. Exergen v. Wal—Mart Stores, Inc., 575 F.3d
19
1312, 1318, 1330 (Fed. Cir. 2009); see generally Therasense, Inc. v.
Becton, Dickinson & Co., 649 F.3d 1276 (Fed. Cir. 2011) (en banc).
Delano Farms Co. v. Calfomia Table Grape Comm’n, 655 F.3d 1337, 1350 (Fed.
Cir. 2011).
In essence, Fera pleads that various persons associated with Fresenius’s
patent prosecution knew that the grandfathered formulations performed well in
stability testing. The very heart of the patent, however, was its claim of
improved stability. These actors therefore allegedly compared the stability of
their formulation, not to the grandfathered product, but to the poor stability
tests of formulations other than the one Fresenius had previously marketed.
They referred to these different formulations as “prior art” or “conventional,”
allegedly with the intent to mislead the patent examiner.
That, in my view, meets the relatively low threshold of being a sufficient
allegation. The motion to dismiss is therefore denied. I move on to the
preliminary injunction aspect.
The Therasense standard applies to the likelihood of success inquiry on a
preliminary injunction. At the preliminary injunction phase, however, the
Court is predicting the future; it is required “to assess the potential of a ‘clear
and convincing’ showing in the future, but in terms of what is ‘more likely than
not’ presently.” Titan Tire, 566 F.3d at 1380. And of course, unlike a motion to
dismiss, a preliminary injunction application requires examination of the
affidavits and proofs put forward by the parties.
The ‘289 patent claims priority over a provisional application, U.S.

41) The ‘289 patent actually issued from non-provisional Patent
Application No. 13/597,884 (“the ‘884 application”). (Fera Answer 42) The three
The inequitable conduct allegations are essentially the same for the other two

inventors listed on the ‘084 application are the same as those on the ‘289
Patent: Zhi—Qiang Jiang, Arunya Usayapant, and George Monen. (See ‘084
application cover sheet; ‘289 Patent)
Page 6 of the ‘084 application contains two tables. The first table
contains the ingredients of five levothyroxine formulations, labeled A—E, that
underwent stability testing. All have 10mg of mannitol and between 100 and
500 pg of levothyroxine. Formulations A and B, labeled as “conventional,”
contain tribasic sodium phosphate. Formulations C, D, and E, labeled as
“modified,” contain dibasic sodium phosphate. The A/B “conventional
formulations,” according to Fera, contain essentially the same formulation as
the grandfathered Bedford formulation. (Fera Answer ¶J 47—50, 74—76)
Formulations C,D, and E contain dibasic sodium phosphate, and are similar to
the formulation that is the subject of the ‘289 patent.
Table 2 lists amounts of liothyronine (or “T3”), a degradation product of
levothyroxine, in formulations C-E tested at different times over 18 months.
(‘084 application at 6) “Each of formulations C, D and E included 0.17
-
0.18%
T3 at the beginning of the testing. The amount of T3 increased over time in
formulations C and D, whereas the amount of T3 in formulation E remained
relatively stable.” (‘084 application at 7
¶
0026) The results as to “conventional”
formulations A and B are not presented in a table, but the ‘084 application
explains in text:
The instability of levothyroxine in the modified formulations C and
D was unexpected in view of the behavior of the conventional
formulations A and B. During storage at 25° C for a period of from
4 to 19 months, the amount of T3 in formulation A varied from
0.16 0.34%, but did not exhibit an increase over time. Likewise,
the amount of T3 in formulation B varied from 0.22 0.27% during
storage at 25 °C for a period of from 8 to 28 months, but did not
exhibit an increase over time.

0028) It further explained that “[sjurprisingly, the
stability of levothyroxine in lyophilized formulations containing dibasic sodium
phosphate instead of tn basic sodium phosphate was found to decrease with an
increase in the ratio of mannitol to levothyroxine in the formulation.” (‘084

¶
0031 (emphasis added; see also Fera Answer
¶
59) In other
words, the stabilizing effect that is the foundation of the claimed invention is
observed in relation to the dibasic, but not the tribasic, formulation.
Here is the problem, says Fera: The non-provisional ‘884 application does
not compare formulations with dibasic sodium phosphate to those with
tribasic. (Fera Answer
¶
65) That ‘884 application was the subject of four
separate office actions. In the fourth rejection the examiner notes that the data
presented by the applicant is not a direct comparison with the relevant prior
art, and that art teaches a formulation containing tribasic sodium phosphate.
(Fera Answer ¶ 120)12 Fera faults the applicants for allegedly never submitting
to the patent examiner the original stability test results on formulations A and
B, which are tribasic sodium formulations. (See, e.g., Fera Answer ¶ 124)
A declaration by Dr. Usayapant was submitted on December 23, 2014,
as part of a response to the fourth rejection. (Usapayant Deci.) In that
declaration Dr. Usapayant refers to the stability benefits of the new formulation
as compared to conventional formulations. She cites to a table comparing
formulations, all containing dibasic sodium phosphate, but containing varying
amounts of mannitol. (Usayapant Deci.
¶
9; see F’era Answer
¶
128)
Usayapant’s declaration elsewhere refers to “prior art,” but Fera complains that
these references do not explicitly distinguish between prior art formulation as
containing dibasic or tribasic sodium phosphate. (Usayapant Decl.
see Fera Answer
¶
¶
14—17;
132—33) Usayapant’s data, however, and her stability
comparisons, clearly relate to dibasic.
The examiner, who was aware of the dibasic/tribasic issue, found the
arguments filed on December 23, 2014, persuasive and issued a notice of
allowance. (Fera Answer
¶
149; Notice of Allowance 2). She highlighted that
12 Fera stresses the number
of times that Fresenius’s applicants represented
that their formulation was an improvement over conventional formulations. If this was
an attempt to fool the patent examiner, as Fera claims, she clearly was not falling for
it, as witnessed by the four rejections. (Fera Answer ¶11 73—118)
22
“since Applicants have discovered that the previous formulations are unstable,
and that decreasing the amount of mannitol to between 2 and 4 mg increases
stability, leading to a more stable product having an increased shelf-life, the
claims of the instant application are novel and nonobvious over the closest
related prior art.” (Notice of Allowance 6)
I see no substantial evidence of misrepresentation, or intentional
withholding of material information from the patent examiner. The analysis is
hampered somewhat by Fera’s failure to depose the persons involved in the
patent prosecution. The necessary intent to deceive, see Delano Farms Co.,
supra, for example, will often depends on such evidence. There is enough here,
however, to demonstrate the point. The patent examiner knew very well that
some of the prior art taught a tribasic formulation. The provisional application,
containing the allegedly omitted information, was before the patent examiner,
who should be presumed to have been familiar with it. More fundamentally,
throughout the process, the relevant apples-to-apples comparison, as
presented to and understood by the examiner, was between dibasic
formulations containing different proportions of mannitol. That was the thrust
and point of the application.
This is one area where the preliminary injunction standard could make a
difference. My finding that Fera has not raised a substantial question is based
primarily on the state of the paper record, but the question is a close one.
Under the traditional Rule 65 standard, I find with more ease that Fresenius
has shown a likelihood of success on patent validity in relation to the
inequitable conduct issue.
v.
Unclean hands
Fera asserts the equitable doctrine of unclean hands. In the present
context, however, this seems to be another name for its other contentions.
Thus, Fresenius is alleged to have unclean hands because it engaged in double
patenting or violated its duty of candor to the USPTO regarding prior art. I have
discussed those contentions more specifically above; they have no more
likelihood of success under the rubric of unclean hands.
23
Fera adds that Fresenius has unclean hands because it did not report
Fera’s own inequitable conduct allegations to the PTO. I do not give significant
weight to this bootstrapping allegation.
B.
Irreparable Harm
Patent law recognizes the necessity of injunctive relief “to preserve the
legal interests of the parties against future infringement which may have
market effects never fully compensable in money.” Hybritech, Inc. v. Abbott
Labs., 849 F. 2d 1446, 1457 (Fed. Cir. 1988).
“LP)rice erosion, loss of goodwill, damage to reputation, and loss of
business opportunities are all valid grounds for finding irreparable harm.”
Celsis In Vitro, Inc. v. CellzDirect, Inc., 664 F.3d 922, 926 (Fed. Cir. 2012). Loss
of market share, for example, “constitutes irreparable injury because market
share is so difficult to recover.” Henkel Corp. v. Coral, Inc., 754 F. Supp. 1280,
1322 (N.D. Iii. 1991), aff’d, 945 F.2d 416 (Fed. Cir. 1991). Price erosion,
because of the difficulty of reversal, may constitute irreparable harm. Canon,
Inc. v. GCC Intl Ltd., 263 F. App’x 57, 62 (Fed. Cir. 2008). The right to exclude
direct competition in a limited sphere, a right inherent in the grant of a patent,
is irreparably harmed by the loss of sales and the competitive foothold that the
infringer will gain. See Systemation, Inc. v. Engel Indus., Inc., 194 F.3d 1331,
1999 WL 129640 at *6 (Fed. Cir. 1999).
In addition to harm as such, the patentee must show that there is a
“sufficiently strong causal nexus” between the infringement and the harm.
Apple Inc. v. Samsung Electronics Co., 695 F.3d 1370, 1374 (Fed. Cir. 2012). In
particular, there must be a connection between the lost sales or market share,
and the “infringing feature” of the competing product. Id. at 1374 (“Sales lost
to an infringing product cannot irreparably harm a patentee if consumers buy
that product for reasons other than the patented feature.”).
Fera indisputably seeks to be Fresenius’s direct competitor. Through its
ANDA, it seeks to market precisely the formulation as to which Fresenius
obtained FDA approval and patent protection. See Systemation, Inc.
24
(emphasizing loss of sales to “direct competitor” as emblematic of irreparable
harm).
In Fera’s view, the presence of the grandfathered product places a
natural ceiling on the value of the patented product, which has a longer shelf
life but the same efficacy. Still, the evidence shows a dramatic increase in the
price of the patented product—in the five- to six- fold range—for which there is
no plausible explanation except for its patented status. The inference is
inescapable that customers are paying a premium for its stability. Fera itself
could presumably market the grandfathered product, but has not chosen to do
so, instead piggy-backing on the FDA-approved Fresenius product, which now
enjoys some $80 million in annual sales. That in itself is suggestive of the value
of the innovation, although I do not discount an element of market
irrationality, lag, or less-than-perfect market information.
Because the product is one administered in hospitals, the customer base
comprises a relatively small class of Group Purchasing Organizations (GPO5).
(Meacham
¶
10) Those customer relations, the reputation of Fresenius, and the
purchasers’ experience with the product, are therefore of primary importance.
The market clout of such GPOs also implies that, should the price erode as a
result of infringement, a price rebound may meet stiff resistance.
Historical sales of the grandfathered product do give us an informational
backdrop. That market, however, has apparently dried up. The market for the
patented product is not mature, or even well established. Thus the effect of
Fera’s projected price cutting on Fresenius’s (currently 100%) market share is
difficult to predict or quantify. And market share, once lost, is difficult to regain
in the event of a mistaken denial of injunctive relief. See Herikel Corp., 754 F.
Supp. at 1322.
Fera cites the presence of a new competitor in the market: Par Sterile
Products, LLC, and affiliates (“Par”). Par, the parties seem to agree, is not
precisely a third-party entrant. Rather, Par has entered into licensing and
distribution agreements with Fresenius on March 18, 2016, and July 1, 2016.
As a licensee, Par is within the patent estate, i.e., under the umbrella of
25
Fresenius’s patent protection. “[T]hat a patentee has license others under its
patents does not mean that unlicensed infringement must also be permitted
while the patents are litigated.” See Acumed LLC v. Stryker Corp., 551 F.3d
1323, 1328 (Fed. Cir. 2008) (citing eBay, 547 at 393); Abbott Labs. V. Sandoz,
Inc., 544 F.3d 1341, 1362 (Fed. Cir. 2008)). A license, an ordinary means of
patent exploitation, does not imply that infringement by a non-licensee is
harmless. At best, it is a weak indicator that damages might be quantified as a
reasonable royalty, but even that is but one factor among many.
The irreparable harm factor tips in favor of Fresenius.
C.
Balance of Harms
On the balance of harms, Fera essentially argues that Fresenius has
made large profits and can well afford competition from Fera. Because some
version of the product has long been in existence, research and development
costs, as well as regulatory approval, allegedly set Fresenius back only $3
million. The product, which has accounted for some $310 million in sales over
the years, supposedly accounts for only 5% of Fresenius’s revenue.
Fera’s argument amounts to a contention that, even if it turns out to
have been infringing, Fresenius can well afford the competitive loss. Fresenius,
however, has made a showing of likelihood of success on the issues of
validity/infringement. The implication is that Fera has not made a strong
showing that it has a right to go to market; it is not likely to suffer a legally
cognizable “loss” by being enjoined. I therefore cannot find that the balance of
harms favors Fera.
D.
Public Interest
Cheaper generic drugs, as Fera points out, are in the public interest.
That argument, of course, proves too much; the patent laws reflect a balance
between that public policy and the policy of encouraging innovation through
