McNeil-PPC et al. v. Perrigo Co., No. 05-1321 (S.D.N.Y. 2007)
In an opinion released Tuesday, Judge William H. Pauley III of the U.S. District Court for the Southern District of New York ruled that McNeil’s patent on the formulation for Pepcid Complete is invalid as obvious, clearing the way for Perrigo Co. to sell its own generic version of the medication. The decision is one of the first pharmaceutical patent decisions to rely on and quote extensively from the Supreme Court’s April 30 decision in KSR v. Teleflex.
The patent-in-suit was McNeil’s U.S. Patent No. 5,817,340. Claim 1 of the ‘340 patent recites a solid oral dosage form comprising impermeably coated famotidine granules and aluminum hydroxide or magnesium hydroxide. Pepcid Complete comprises coated famotidine granules (to inhibit stomach acid secretion) and magnesium hydroxide (to neutralize stomach acid already present). The coating on the famotidine granules is important; without it, magnesium hydroxide would cause famotidine to degrade upon contact. Additionally, the coating masks the bitter taste of famotidine.
According to Judge Pauley’s opinion, two prior art references, "Davis" and "Wolfe," had previously taught the use of famotidine with magnesium hydroxide in a pharmaceutical composition. Moreover, according to the opinion, two prior art patents, the ‘072 and ‘114 patents, taught coating of famotidine granules in order to mask famotidine’s bitter taste.
Judge Pauley began his analysis by referring to the "teaching, suggestion, or motivation" test as follows: "Until recently, the Federal Circuit had employed an additional test for determining the obviousness of combining prior art references." Then, after reviewing the scope and content of the prior art, he stated: "Under KSR, ‘the combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.’ The ‘340 patent does no more than combine the predictable results of Davis and Wolfe with the predictable results of the ‘072 and ‘114 patents."
Judge Pauley went on to imply that even pre-KSR, he would have found the ‘340 patent invalid as obvious, since one of skill in the art "would have been motivated to use impermeable coating to improve the palatability of a chewable tablet comprised of coated famotidine and antacids." Nonetheless, the decision is still informative of how district courts are applying KSR to pharmaceutical formulation patents.
Ortho-McNeil, a unit of Johnson & Johnson, markets Pepcid Complete in partnership with Merck. Pepcid Complete is an over-the-counter product intended for the treatment of heartburn, with annual retail sales of about $90 million. Perrigo reportedly plans to begin selling its generic version sometime next year, and expects to have 180-day exclusivity when it does.

In re Omeprazole Patent Litigation, No. MDL-1291 (JPML 2007)
In a lengthy decision released last Thursday, Judge Barbara S. Jones upheld the validity of AstraZeneca's two formulation patents on Prilosec (U.S. Patent Nos. 4,786,505 and 4,853,230) and found that Apotex and Impax infringe the patents while Mylan and Lek (a division of Sandoz) do not. The defendants had challenged the validity of the patents on grounds of lack of best mode, enablement and written description under § 112; public use and disclosure under § 102(b); and obviousness under § 103(a).
The decision marks another milestone in patent litigation that began seven years ago, when AstraZeneca filed suit against at least eight companies that filed ANDAs for generic versions of Prilosec. In a 2002 decision that was later affirmed
by the Federal Circuit, Judge Jones found that Andrx, Cheminor and Genpharm infringe the same two patents and that Schwarz Pharma does not.Separately, Judge Jones also recently denied
Impax's motion to dismiss the suit against it for lack of subject matter jurisdiction. Impax argued in its motion that the suit should have been dismissed because the '505 and 230 patents expired on April 20, 2007 and AstraZeneca had dismissed its claim for damages against Impax. The court, however, found that AstraZeneca has pediatric exclusivity on Prilosec until October 20, 2007, and therefore the court still has jurisdiction to enjoin Impax from selling any additional generic Prilosec until that date.RELATED READING:

Guest Post by Prof. Christopher M. Holman, UMKC School of Law
In my view, the Solicitor General was correct in recommending denial of
certiorari in Joblove, but erred in
its characterization of the majority opinion. For example, the Solicitor General’s brief implies that at the time of the
settlement the parties intended to park Barr’s 180-day exclusivity, preventing
market entry by other generics. In fact, at the time of the settlement,
the FDA interpreted Hatch-Waxman as requiring the first ANDA filer to "successfully defend" against a suit for infringement as a prerequisite to
earning 180-day generic exclusivity. See 21 C.F.R. §
314.107(c)(1) (1995). Thus,
the parties settled with the understanding that Barr was forfeiting its chance
for 180-day exclusivity. The Second Circuit explicitly noted this fact, and that the settlement "cleared the field" for other generic challengers, a factor weighing
against a finding of antitrust violation.The Solicitor General’s brief also criticized the majority opinion for
applying an insufficiently stringent standard for scrutinizing reverse
payment settlements, implying that the majority test would find a settlement
valid unless the underlying lawsuit was a sham or "objectively baseless in
the sense that no reasonable litigant could realistically expect success on
merits." The brief also implied that the
majority’s approach was at odds with the standard articulated by the Eleventh
Circuit in Schering and Valley Drug. But in fact, the Second Circuit test would
find an antitrust violation if the underlying lawsuit was objectively baseless,
or, in the alternative, if the terms of the settlement created "an
extension of the monopoly beyond the patent’s scope." Note that these are alternative tests–an
antitrust violation could be found if the agreement exceeds the scope of the
patent, regardless of whether the underlying suit is objectively baseless or a
sham. This test is not substantially
different from the Eleventh Circuit’s test, which looks to the extent that the
agreement exceeds "the scope of the exclusionary potential of the
patent."Both tests leave the door open for at least some limited of assessment
of the merits of the underlying patent suit, for how can a court make a
determination of the exclusionary potential of a patent without at least
implicitly considering validity/enforceability and construing and applying the
claims? Under both the Eleventh and
Second Circuit approaches, a court could find that a settlement exceeds the reasonable
scope of the patent grant in a situation where at the time of settlement the
patent appeared likely to be found invalid or unenforceable. Although the brief asserts that in Schering the
Eleventh Circuit "did not foreclose the possibility that a party challenging a
patent settlement could rely on an ex ante view of the strength of the infringement
claim," it provides no citation to any text in the Schering decision that would
support this view. I have looked, and I
don’t think there is anything that would necessarily render the Second and
Eleventh Circuit tests inconsistent.Note also that while the brief suggests that the correct standard would
assess the merits of the underlying patent case, the FTC has in the past
characterized such an assessment as "not supported by law or logic." Schering, 402 F.3d 1056, 1068 n.18.Readers interested in a further discussion explaining the basis for my assertion that there is in fact no substantial split between the Eleventh and Second Circuits (as well as Sixth Circuit) on this issue might want to take a look at my recent article on reverse payment settlements: Christopher M. Holman, Do Reverse Payment Settlements Violate The Antitrust Laws?, 23 Santa Clara Computer & High Tech. L.J. 489 (2007). The article will soon be available on SSRN, or I would be happy to send a copy to anyone that is interested. My email is holmancm@umkc.edu.

Via the Antitrust Review and Pharmalot, the Solicitor General has recommended that the Supreme Court deny certiorari in Joblove v. Barr Labs, the most recent “reverse payments” case to be appealed to the Court. Last year, the Solicitor General advised the Court not to take the FTC v. Schering case. At the time, many observers thought this case might better present the reverse payments issue.
But apparently the Solicitor General disagreed. In an amicus brief requested by the Supreme Court in March and filed this month, the Solicitor General acknowledged that the case raises important questions and criticized the appeals court decision, but advised the Court that “this case does not present a good vehicle for addressing the question presented.” The cert petition presented the following question for review:
Whether the federal antitrust laws prohibit a brand name drug patent holder and a prospective generic competitor from settling patent infringement litigation by agreeing that the generic manufacturer will not challenge the validity of the patent or market its own version of the drug until the expiration of the patent, in exchange for a substantial payment from the patent holder.
The Solicitor General’s brief advised the Court that the Second Circuit adopted an insufficiently stringent standard for scrutinizing reverse payment settlements when it held that a settlement is valid unless the underlying lawsuit was “objectively baseless in the sense that no reasonable litigant could realistically expect success on merits.” In the Solicitor General’s view, a court evaluating a reverse payment settlement should engage in a “broader inquiry concerning the patent holder’s likelihood of success on that claim.”
Ultimately, however, the Solicitor General concluded that this is not an appropriate case for review, since the “federal antitrust claims in this case appear to be moot, the factual setting is atypical and unlikely to recur, and subsequent regulatory changes may undercut one of the theories of competitive harm advanced by petitioners.”
The Federal Trade Commission, which has campaigned vigorously against reverse payment settlements, is probably very disappointed with the Solicitor General’s recommendation to deny cert. My understanding is that the FTC will not have an opportunity to submit its own brief in this case, since the government may only submit a single amicus brief to the Supreme Court (the FTC was a party in FTC v. Schering, so of course it submitted its own brief in that case). Officials at the FTC have revealed that their current strategy is to try to create a circuit split that the Supreme Court will have no choice but to resolve.

Merck & Co. v. Apotex, No. 06-230 (D. Del. 2007)
Last month (as we reported then), the U.S. District Court for the District of Delaware granted Merck’s motion to dismiss the patent suit Merck filed against Apotex concerning generic Fosamax. The court indicated at the time that an opinion would "follow at the court’s earliest convenience." On Monday, the court issued the promised opinion.
Merck moved to dismiss the case after granting Apotex a covenant not to sue on any of the nine patents-in-suit. Apotex opposed the motion on grounds that it was entitled to a "court decision" of invalidity or non-infringement, which would have triggered the first ANDA filer’s 180-day exclusivity period. That would have allowed Apotex to launch its own generic Fosamax sooner–either by forcing the first filer to launch its generic Fosamax earlier or by causing the first filer to forfeit its exclusivity.
Predictably, the court concluded that the covenant not to sue extinguished any case or controversy. The court stated:
Having received a covenant not to sue, Apotex does not and cannot allege "unlawful conduct" attributable to Merck. Further, Apotex’s articulated injury–delayed entry to the market–is not fairly traceable to Merck. There is no evidence to conclude that Apotex’s delayed entry into the market is any different than what it would have been had Merck never sued it. Thus, Apotex’s advancement of this case against Merck becomes merely a means to an end, where the desired "end" is a triggering event but the means to that end, the litigation itself, is not sanctioned under the current legal framework. To proceed to a substantive "court decision" on the merits of Apotex’s claims of noninfringement or invalidity would amount to an impermissible advisory opinion.
The court also addressed Apotex’s motion to amend its pleadings to add an antitrust counterclaim. Apparently, in its motion to amend Apotex argued that Merck’s 30-month stay on FDA approval of Apotex’s ANDA would not be terminated upon dismissal of the lawsuit, causing additional antitrust injury to Apotex. My understanding has always been that dismissal of a case terminates the 30-month stay. According to the district court, however, that is not so clear.
The relevant statute is 21 USC 355(j)(5)(B)(iii). Merck argued that the statutory language instructs that a dismissal for lack of jurisdiction would lift the 30-month stay. Apotex, on the other hand, asserted that the FDA has not yet construed the statute. According to the court, "neither the parties nor the court can be certain of how the provision will be applied to Apotex." Interestingly, the court noted that at one time FDA proposed a rule that would have answered the question directly (with the answer being that dismissal lifts the stay), but later withdrew the rule without comment. (Does anyone know of a case in which FDA lifted a 30-month stay because the lawsuit was dismissed?)
The court acknowledged the potential for abuse "if the mere filing of a patent infringement suit can result in an irrevocable 30-month stay," but in the end, concluded that Merck’s actions were perfectly legal under the Hatch-Waxman regime. Therefore, according to the court, Apotex does not have a cognizable antitrust injury.

Pfizer v. Apotex, No. 2006-1261 (Fed. Cir. 2007)
This afternoon, the Federal Circuit denied Pfizer’s petition for rehearing and rehearing en banc of Pfizer v. Apotex, in which the court invalidated claims 1-3 of Pfizer’s U.S. Patent No. 4,879,303. The ‘303 patent covers amlodipine besylate, the active ingredient in Norvasc.
Three of the twelve judges ruling on Pfizer’s petition dissented from the decision not to rehear the case en banc: Newman, Lourie, and Rader. Each of the three filed dissenting opinions.
Judge Newman voiced strong disagreement with the three-judge panel opinion, writing that "the panel’s application of the obvious-to-try standard is in direct conflict with precedent" and "the panel decision changes the criteria as well as the analysis of patentability." Judge Lourie expressed his view that "the panel erred in its legal determinations, and those errors will confuse the law relating to the rebuttal of a prima facie case of obviousness of a chemical compound." Both Newman and Lourie are chemists by training. Judge Rader stated that the panel gave insufficient deference to numerous factual findings of the district court, and substituted its own judgment on those issues. He concluded: "this decision calls into question countless pharmaceutical patents, which in turn could have a profoundly negative effect on investments into the design and development of new life-saving pharmaceuticals."
The most immediate beneficiary of today’s decision may be Apotex. The FDA announced last month that it would grant final approval to Apotex’s ANDA for generic Norvasc when the Federal Circuit issues a mandate in Pfizer v. Apotex. In addition to denying Pfizer’s petition to rehear the case today, the Federal Circuit also granted Apotex’s motion for expedited issuance of the mandate and issued the mandate. Thus, Apotex’s final approval appears imminent.
As we previously reported, Mylan, who currently has the only approved ANDA for generic Norvasc, filed suit to enjoin FDA from approving any other generics. Mylan lost that case and appealed to the D.C. Circuit. Mylan might now file an emergency motion with the D.C. Circuit, aiming to prevent FDA from approving Apotex’s ANDA until the appeal is decided.
