`
`C was often offset by concurrent treatment with statins.6337 The safety and efficacy of using
`
`prescription omega-3 in combination with a statin has been well-established.6338
`
`Although an increase in LDL-C was generally observed when omega-3 fatty acids were
`
`administered to patients with very-high TG levels, the increase in LDL-C was not necessarily a
`
`cause for concern because LDL-C is often low in patients with severe hypertriglyceridemia.
`
`Therefore, the final LDL-C concentration may still be in the normal range.6339 Furthermore, it
`
`was understood that the overall lipid effect of Lovaza/Omacor was beneficial.6340
`
`In two pivotal studies in very-high TG patients, both of which used prospective,
`
`randomized, double-blind, placebo-controlled study designs, Lovaza/Omacor increased HDL
`
`levels from baseline 13% (p=0.014) and 5.9% (p=0.057).6341 Correspondingly, prescription
`
`omega-3 fatty acids were known to have favorable effects on non-HDL-C levels.6342 Therefore,
`
`“[i]n patients with very-high triglyceride levels, prescription omega-3 fatty acids 4 g/day can
`
`substantially reduce triglycerides and VLDL levels and may increase LDL levels, but the net

`increase in LDL, which was substantial on a percentage basis, has been a common finding in past studies in [very-
`high TG] patients. It may not be as problematic as it appears, however,” and “the use of omega-3 fatty acids for the

`pancreatitis, but also for the long-term prevention of CHD”); Bays III at 248 (“No clinical trial data exist that this
`rise in LDL-C represents harm or potential “toxicity” to patients. In fact, most evidence supports that omega-3 fatty
`acids reduce cardiovascular risk as do fibrates. Importantly, clinical trials mostly support that even with increases in
`LDL-C, omega-3 fatty acids decrease the total cholesterol (TC) carried by atherogenic lipoproteins, as reflected by

`
`effect is a reduction in non-HDL levels. Modest increases in HDL level are also common in
`
`patients treated with prescription omega-3 fatty acids.” Prescription omega-3 therapy was also
`
`known to alter lipoprotein particle size and composition in a favorable manner by decreasing the
`
`number of small, dense LDL particles to larger LDL particles.6343 Lovaza/Omacor “adversely
`
`raise[d] LDL cholesterol concentration but the increase in LDL cholesterol concentration
`
`reflect[ed] a less atherogenic light LDL subfraction profile that may be favorable.”6344
`
`Therefore, one of ordinary skill in the art believed that the use of Lovaza/Omacor, and omega-3
`
`fatty acids generally, “for the treatment of severe hypertriglyceridemia may be beneficial not
`
`only for the short-term prevention of acute pancreatitis, but also for the longer-term prevention
`
`of [coronary heart disease].”6345
`
`Therefore, contrary to Defendants’ assertion that “a person of ordinary skill in the art at

`reduce TG levels in patients with TG levels of at least 500 mg/dL without negatively impacting
`
`LDL-C levels,”6346 one of ordinary skill in the art at the time of the invention understood that the
`
`rise in LDL-C caused by omega-3 fatty acids was a by-product of reducing TGs in patients with
`
`very-high TG levels. A person of ordinary skill in the art would have expected LDL-C to
`
`increase in very-high TG patients, and in some instances the rise was not concerning because
`
`LDL-C is often low in patients with severe hypertriglyceridemia and therefore final
`
`concentration would still be in the normal range. When LDL-C levels increased beyond what
`
`was recommended by the ATP-III, prescribers often relied on statins to safely and effectively

`
`Lovaza/Omacor was beneficial because non-HDL-C levels often increased. Defendants fail to
`
`identify any other basis upon which a person of ordinary skill would have been motivated to find
`
`a therapy that would reduce TG levels in patients with very-high TG levels without negatively
`
`impacting LDL-C levels. Further, a person of ordinary skill in the art would have understood
`
`that EPA therapy would not reduce Apo-B6347 (which is a reflection of total atherogenic
`
`lipoproteins) 6348 in very high TG patients, and accordingly would not have been motivated to
`
`administer the claimed EPA composition to the very high TG patient population.
`
`Defendants make the conclusory allegation that “routine optimization” by a person of
`
`ordinary skill would yield the claimed invention.6349 Defendants, however, have offered no
`
`explanation to support that allegation and they further fail to establish any of the required criteria
`
`of “routine optimization” or the prerequisites to this argument. They also fail to provide any
`
`factual detail to support their allegation and they fail to link the allegation to any particular claim
`
`or claim element. Defendants mere allegation constitute an improper placeholder to later
`

`
`for the reasons discussed herein, a person of ordinary skill would not be motivated to make the
`
`combinations alleged by Defendants and, for the same reasons, it would not be routine to
`
`combine such references. Where, for example, defendants argue that it would be routine to go

`
`A Person of Ordinary Skill Would Not Have
`Had a Reasonable Expectation of Success
`with the Combinations Defendants
`Hypothesize
`
`Defendants provide no evidence that a person or ordinary skill would have had a
`
`reasonable expectation of successfully obtaining the claimed invention—a method of reducing
`
`triglycerides in a subject having very-high triglyceride levels by administering EPA of the
`
`recited purity to effect a reduction in triglycerides without substantially increasing LDL-C—by
`
`combining the references cited by defendants. For a particular combination of references, there
`
`must be a reasonable expectation that the combination will produce the claimed invention. In
`
`this case, the art taught that DHA and EPA have similar effects on LDL-C levels in patients with
`
`very-high TG levels.6351 A person of ordinary skill would have expected EPA, like
`
`Lovaza/Omacor, to raise LDL-C levels when administered to patients in the very-high TG
`
`patient population. As discussed in Section III and above, it was well known that TG-lowering
`
`
`6351 As discussed above, see supra section III, a person of ordinary skill would have understood EPA and DHA to
`have the same TG lowering mechanism and would have further understood that the increase in LDL-C
`accompanying the TG-lowering effects of Lovaza was a product of that same mechanism. Accordingly, a person of
`ordinary skill would have expected EPA to increase LDL-C levels in patients with very-high TG levels in similar
`fashion to Lovaza or DHA alone.

`
`skill to expect anything to the contrary. A person of ordinary skill would have understood that
`

`
`Accordingly, a person of ordinary skill would not have a reasonable expectation of

`
`with very-high TG levels.6354
`
`Defendants’ position that a person of ordinary skill would have had a reasonable
`
`expectation of success in administrating purified EPA to patients with very high triglyceride
`
`levels to achieve TG lowering without substantially increasing LDL-C is belied by the fact that
`
`Defendants’ provide no evidence that anyone thought to administer Epadel.6355 Epadel was
`
`available for many years prior to the invention of the ’594 patent, to patients with very-high TGs
`
`as a treatment. A person of ordinary skill did not expect Epadel, which consisted of mostly EPA,

`6354 Indeed, as discussed above, a person of ordinary skill would have understood that DHA had a better overall
`effect on lipid parameters, teaching away from this combination.
`6355 Although Epadel was available at different levels of purity, the fact that Epadel—at any level of purity—was not
`examined in any study directed to the very-high TG patient population supports Amarin’s position.

`
`to have superior qualities over a drug such as Lovaza/Omacor, which comprised a mixture of
`
`EPA and DHA, in patients with very-high triglycerides. Indeed, none of clinical studies cited by
`
`Defendants are directed to the use of purified EPA in the very-high TG population.
`
`Research into the pharmaceutical uses of EPA started as early as the 1970s. In 1990,
`
`Mochida Pharmaceutical, began to market Epadel, a high purity EPA drug. There have been
`
`countless studies conducted which administer Epadel and report the effects observed. Although
`
`a few studies administer Epadel to a patient population which included a few patients with TG
`
`levels > 500 mg/dL, Defendants fail to identify a single reference directed to the administration
`
`of Epadel to patients with very-high TG levels. The fact is, a person of ordinary skill did not
`
`expect Epadel, which consisted of mostly EPA, to have superior qualities over a drug such as
`
`Lovaza/Omacor, which comprised a mixture of EPA and DHA, in patients with very-high
`
`triglycerides.
`
`Defendants argue that because Grimsgaard administered purified ethyl EPA to patients
`
`with borderline-high/high TG, it would have been obvious to try administering purified ethyl
`
`EPA to patients with very-high TG levels with a reasonable expectation of success. Defendants
`
`base this unsupported conclusion on Grimsgaard, Lovaza/Omacor, the known administration of
`
`2.7 grams of purified EPA to patients with greater than 500 mg/dL TG by Matsuzawa.6356
`
`Defendants’ contentions are no more than a demonstration that certain claim elements was
`
`known in the prior art and demonstrates impermissible hindsight reconstruction.6357 As is
`
`reflected in Table 4 of Grimsgaard, the study authors found no difference between the DHA,

`EPA, and control in terms of LDL-C levels. Defendants use hindsight to argue that, despite EPA
`
`and DHA showing the same effect on LDL-C, one would have chosen EPA and expected that
`
`administration to very-high TG would have resulted in little or no impact on LDL-C. Notably,
`
`none of these references would provide a person of ordinary skill in the art with a reasonable
`
`expectation of successfully obtaining the claimed invention even if there were reasons to
`
`combine disparate, independent elements found in the prior art, which there were not.
`
`
`
`In addition, Grimsgaard was conducted in patients with normal TG levels, so a person of
`
`ordinary skill would have expected no difference between EPA and DHA in terms of LDL-C
`
`level change and would have expected no significant increase (or decrease) in LDL-C, as
`
`reported by that publication. A person of ordinary skill would further have understood that the
`
`data reported by Grimsgaard to be consistent with the understanding that while LDL-C levels are
`
`not significantly impacted in normal to high TG patient populations, LDL-C levels would
`
`increase significantly in very-high TG patients.
`
`Matsuzawa similarly provides no basis for a reasonable expectation of success in
`
`achieving the claimed invention. The subjects of Matsuzawa had a wide range of baseline TG
`
`levels and the study was not directed to the very-high TG patient population. Accordingly, just
`
`as with Grimsgaard, Matsuzawa would not provide a reasonable expectation of success as a
`
`person of ordinary skill would understand patients with very-high TG levels to be different in
`
`terms of LDL-C effect than patients with lower TG levels.

`
`
`
`To the extent that Defendants’ arguments are based on results that are not statistically
`
`significant and not reported by Grimsgaard as significant, a person of ordinary skill would not
`
`draw conclusions from these statistically insignificant differences. Indeed, the standard
`
`deviation for the changes reported is greater than the value of the change itself.
`
`Defendants argue that it would have been obvious to try administering purified ethyl EPA
`
`to patients with very-high TG levels with a reasonable expectation of success. However, the
`
`Federal Circuit has often rejected the notion that showing something may have been “obvious-to-
`
`try” proves that the claimed invention was obvious where the prior art did not suggest what to
`
`try.6358 Rather than there being a limited number of options, the state of the art provided a
`
`plethora of compositions and administration protocols associated with multiple kinds of TG-
`
`lowering therapies.6359 There were not a finite number of options for a person of ordinary skill
`
`seeking to reduce TG levels without increasing LDL-C among the very-high TG patient
`
`population.
`
`Defendants argue that a person of ordinary skill at the time of the invention, based on
`
`studies in normal, borderline-high and high TG patients, knew that administration of DHA alone
`
`resulted in undesirable increased LDL-C levels while administration of EPA alone had little to
`
`no impact on LDL-C levels.6360 However, that statement does not conform with what was
`
`known regarding the effect of Epadel and Lovaza/Omacor in normal, borderline-high and high
`
`TG patients. Instead as Defendants’ own prior art demonstrates, Epadel and Lovaza/Omacor

`
`With the lack of any reasonable expectation of success, Defendants argue that their
`

`
`that that these changes yield predictable results.6361 Such an argument, however, represents pure
`

`
`WO ‘118 is directed at the composition containing EPA for the purpose of preventing the
`
`occurrence of cardiovascular events in multiple risk patients. Further, the invention of WO ‘118
`
`is directed, “in particular, [to] preventing occurrence of cardiovascular events in
`
`hypercholesterolemia patients who have been treated with HMG-CoA RI but still suffer from the
`
`risk of the cardiovascular events.”6368 Contrary to Defendants’ assertion that WO ‘118 discloses
`
`“the administration of 4 g of pure EPA with no DHA,”6369 WO ’118 fails to disclose the claimed
`
`subject with the specified very high TG levels (at least 500 mg/dL) who does not receive
`
`concurrent lipid altering therapy, the claimed pharmaceutical composition with the specified
`
`fatty acid compositions or dosage, or the claimed method to effect the specified TG reduction
`
`without substantially increasing LDL-C. WO ‘118 discloses a composition with a wide range of
`
`possible EPA content, dosages, and teaches that DHA is a “preferable fatty acid” to include in
`
`the disclosed composition.6370
`
`WO ’118 does not disclose administration of highly-purified ethyl-EPA to the target
`
`population of the claimed invention. The asserted claims are directed to persons with severe
`
`hypertriglyceridemia (i.e. TG level above 500 mg/dL). WO ’118 on the other hand only
`
`discloses administration of EPA to persons with triglyceride of at least 150 mg/dL.6371 WO

`’118’s emphasis on reducing cardiovascular events suggests that its disclosure is directed to

`patients with borderline-high to high TG levels, since the primary goal for patients with very-
`
`high TG is to prevent acute pancreatitis by decreasing TG levels.6372
`
`WO ’118 also does not distinguish EPA from DHA in its disclosures regarding the
`
`effectiveness of the substances for treating hypertriglyceridemia.6373 WO ’118 states that
`
`“[a]nother preferable fatty acid . . . is DHA-E,” and that “the compositional ratio of EPA-
`
`E/DHA-E, content of EPA-E and DHA-E . . . in the total fatty acid, and dosage of (EPA-E +
`
`DHA-E) are not particularly limited as long as intended effects of the present invention are
`
`attained.”6374 It further states that “the composition is preferably the one having a high purity of
`
`EPA-E and DHA-E.”6375 Further, WO ’118 does not disclose EPA’s effect on LDL-C, VLDL-C,
`
`Apo-B, or Lp-PLA2.
`
`WO ‘900 is directed to a process for producing purified EPA from a culture of micro-
`
`organisms. WO ‘900 fails to disclose the claimed subject with the specified very high TG levels
`
`(at least 500 mg/dL) who does not receive concurrent lipid altering therapy, the claimed
`
`pharmaceutical composition with the specified dosage or administration period, or the claimed
`
`method to effect the specified TG reduction without substantially increasing LDL-C. WO ‘900
`
`only discloses the method of producing purified EPA for therapeutic use, it does not teach
`
`administration of pure EPA. WO ‘900 has no discussion, for example, regarding claimed patient
`
`population or method of treatment.

`
`
` WO ‘900 does not teach administration of pure EPA to treat hypertriglyceridemia. It
`
`lists more than 30 diseases that can be treated with pure EPA, but hypertriglyceridemia is not one
`
`of them.6376 Moreover, WO ‘900 does not teach the desired effect of EPA other than
`
`commenting generally that it “may promote health and ameliorate or even reverse the effects of a
`
`range of common diseases.”6377 It has no discussion, for example, on any TG-lowering effect of
`
`EPA. Although WO ‘900 identifies DHA as an “undesired molecule”, it does not identify the
`
`specific undesired effect of DHA or other impurities it is trying to prevent other than
`
`commenting generally that “the desired effects of EPA may be limited or reversed” by them.6378
`
`It has no discussion related to any LDL-C effects caused by DHA.
`
`The proposed combination does not render the independent claims of the ’594 Patent
`
`obvious and Defendants’ burden to prove otherwise is especially difficult because the PTO
`
`considered WO ‘118, WO ‘900, Mori 2000, and Lovaza (both generally and the Lovaza package
`
`insert specifically) during prosecution.6379, 6380
`
`
`6376 See, e.g., ’900 Pub. at 16-17.
`6377 ’900 Pub. at 5.
`6378 ’900 Pub. at 39.
`6379 See, e.g., Mintz v. Dietz & Watson, Inc., 679 F.3d 1372, 1377 (Fed. Cir. 2012)(taking into account that “the
`examiner considered during prosecution all the prior art cited by [the defendants] against the claimed invention.
`Thus, the examiner found that the prior art applied in this case had not precluded patentability even before the clear
`and convincing standard came into play”).
`6380 Defendants also argue that “[t]he administration of 2500 mg to 5000 mg of ethyl eicosapentaenoate would have
`been obvious to one of skill in the art based on the teaching of Kris-Etherton that effective doses of omega-3 fatty
`acids range from 3 to 5 grams per day, which can only be obtained consistently by supplementation.” They are
`incorrect. Kris-Etherton teaches that patients in need of TG lowering should consume “two to four grams of
`EPA+DHA per day.” Kris-Etherton at 9. Kris-Etherton does not distinguish between EPA and DHA and in fact
`recommends the administration of EPA and DHA together. Kris-Etherton does not provide any teaching related to
`the administration of EPA alone. In addition, Defendants have offered no specific combination of references that
`includes Kris-Etherton and accordingly have not met the requirements of the Local Patent Rules and the law of
`obviousness.

`The analysis of the independent claims of the ‘594 patent is incorporated into all asserted
`

`
`(a)
`
`Leigh-Firbank and Mori 2000 Do
`Not Disclose Purported Knowledge
`that DHA was Responsible for the
`Increase in LDL-C
`
`Defendants contend that a “person of ordinary skill in the art would have been motivated
`
`to administer pure EPA to severely hypertriglyceridemic patients according to Lovaza’s known
`
`regimen, particularly in light of the knowledge that DHA is responsible for the increase in LDL-
`
`C levels as evidenced by Leigh-Firbank or Mori 2000.”6381
`
`Defendants fail to identify a specific motivation to combine WO ‘118 or WO ‘900 with
`
`the treatment regimen of Lovaza, as evidenced by the Lovaza PDR. Although Defendants need
`
`not point to an explicit statement in the prior art motivating the combination of these references,
`
`any assertion of an “apparent reason” to combine must find a basis in the factual record.6382
`
`Defendants’ unsupported cobbling of selective disclosures represents hindsight
`
`reconstruction.6383 Defendants’ contentions are no more than an assertion that certain claim

`formalism of earlier decisions requiring a ‘teaching, suggestion, or motivation’ to combine prior art references, it did
`not remove the need to anchor the analysis in explanation of how a person of ordinary skill would select and apply
