OPINION
I. INTRODUCTION
This patent action is brought by Plaintiffs Graceway, LLC (“Graceway”) founded in 2006, and Plaintiff 3M Innovative Products Co. (“3M IPC”) against Defendant Nycomed U.S. Inc. (“Nycomed”) for allegedly infringing Graceway’s '672 Patent (Patent No. 7,655,672) which was approved on February 2, 2010. Suit was filed February 23, 2010. Nycomed launched its allegedly infringing product on February 25, 2010, and a temporary restraining order (“TRO”) was sought by Plaintiffs on February 28, 2010 based on a limited evidentiary record. On March 8, 2010,
Plaintiffs have now sought a preliminary injunction after limited discovery. For the reasons elaborated below, the Court will DENY the motion for a preliminary injunction.
II. FACTS AND PROCEDURAL POSTURE
As the facts are well known to the parties, the Court refers the reader to the facts as developed in this Court’s March 8, 2010 opinion. See Doc. No. 40. Since that time Defendants Perrigo Company and Perrigo Israel Pharmaceuticals Ltd. have been dismissed from this suit; Nycomed has filed a Motion to Dismiss Pursuant to Rule 11, and Graceway has filed the instant motion for a preliminary injunction. *569 The Court will address Nycomed’s Rule 11 motion to dismiss in a separate opinion and order, which will follow in short order. This opinion responds to Graceway’s motion for a preliminary injunction.
III. LEGAL STANDARD
The legal standard for granting a preliminary injunction is well-settled.
See
Fed. R. Civ. P. 65(a). “The four factors relevant to the district court’s decision to grant or deny a preliminary injunction are (1) the likelihood of the patentee’s success on the merits; (2) irreparable harm if the injunction is not granted; (3) the balance of hardships between the parties; and (4) the public interest.”

IV. ANALYSIS
This opinion discusses the four factor test for granting a preliminary injunction and certain threshold defenses.
A. Threshold Defense: Dilatory Conduct
A legal right against infringement, even where established, does not, without more, establish a right to injunctive relief. Injunctive relief, particularly where a party seeks preliminary relief, based on a limited record, is, as all authorities acknowledge, not a matter of mere legal right, that is, injunctive relief is not a “standard remedy;” rather it is a form of “extraordinary” relief.
Eli Lilly & Co. v. Am. Cyanamid Co.,
In 2007, Defendant Nycomed sent Plaintiff Graceway a notice letter in regard to Nycomed’s ANDA application for its product, a proposed bioequivalent to Grace-way’s Aldara. Graceway received this notice letter after Graceway had applied for the '672 Patent. At that time, Graceway took no concrete action putting Nycomed on notice of litigation risk and, again, took no such action, including filing a complaint, in immediate consequence of actual approval of the '672 Patent on February 2, 2010. Instead, Plaintiff filed its complaint on February 23, 2010, and the TRO was filed on February 28, 2010. Plaintiffs’ TRO briefing was void of substantial explanation in regard to Plaintiffs’ failure to contact Nycomed and in regard to why Plaintiffs’ failed to put Nycomed on express notice of its litigation risk prior to February 23, i.e., that Graceway would sue to enjoin exploitation of the '672 Patent, a
*570
patent that Graceway does not practice. Nor did the TRO briefing account for the delay in the period between February 2 and February 23. Given the lack of explanation, and the Court’s preliminary determination based, on the limited record at the TRO stage, that damages to Nyeomed were likely and could have been minimized by earlier suit (or, even by earlier letter communications from Graceway to Nyeomed),
A.C. Aukerman Co.,
On further reflection, in view of a better developed record, it is clear that both parties could have acted more diligently. It is also reasonable to conclude that Nyeomed knew of the '672 Patent not only prior to its launch, but also prior to Plaintiffs’ filing this suit. Each party knew or had substantial knowledge of what the other party was doing in terms of the ANDA filing and the '672 Patent. And although each party could have exercised more caution, by putting the other party on express notice of the concrete litigation risks involved, the parties here are sophisticated and knew or should have known of those risks. The equities here are close and the Court is now unwilling to conclude that Plaintiffs’ conduct was dilatory. Moreover, in order to establish laches, a defendant must make a showing in regard to material prejudice.
Intirtool, Ltd. v. Texar Corp.,
B. Nycomed’s License Defense
Nyeomed argues that because Plaintiff 3M recently granted (former Defendant) Perrigo a license under the '672 Patent, Graceway no longer holds an exclusive license and therefore lacks standing to sue. Graceway responds that the licensing agreement is between Graceway and Perrigo, with the latter as sublicensee of the former. Graceway therefore holds an exclusive license from 3M and it (Grace-way) has sublicensed to Perrigo. This is a factor militating in favor of Graceway as an exclusive licensee, which therefore continues to have standing.
See Sicom Sys., Ltd. v. Agilent Techs., Inc.,
Moreover, the Court notes that neither party has put forward the license agreement at issue. See Sicom Sys., 427 F.3d *571 at 976 (“Each license and assignment is unique, therefore this court must ascertain the intention of the parties and examine the substance of what [the licensing agreement] granted to determine if it conveys all of the substantial rights in the patent and is sufficient to grant standing to the licensee.”). Because Nycomed has had access to discovery, and it has, nevertheless, failed to put forward the agreement, it appears that Nycomed’s defense fails.
C. Nycomed’s Remaining Defenses
Nycomed argues that Graceway has taken inconsistent positions in these proceedings and before the FDA in regard to Nycomed’s Product. Nycomed’s position — apparently akin to judicial estoppel — comes absent any supporting legal authority. Arguments absent substantial development are waived.
See Conroy v. Leone,
Likewise, Nycomed argues that Grace-way refused to provide it with the procedures Graceway followed to duplicate or test its (Nycomed’s) product. But what particular information Nycomed lacked is left unexplained. Nycomed has had access to discovery. If it had an entitlement to such information during these proceedings, there was (and yet remains) in place a process by which it could seek this information. If Graceway failed to produce such sought after information, Nycomed could move to compel. No such motion has been brought to this Court’s attention. If Nycomed has not availed itself of these discovery procedures, it has no cause for complaint.
Finally, Nycomed argues that no injunction should issue to keep new technology off the market facilitating an important public need where the patent holder does not practice the patent. As a mere abstract point of law, there is case law supporting Nycomed’s position. However, Nycomed does not put forward any concrete evidence tending to establish that its product fills just such a public need not already filled by Aldara, Graceway’s product.
D. The Four Factor Test For Injunctive Relief
1. The Likelihood Of The Patentee’s Success On The Merits
Defendant does not actively contest Plaintiffs’ claim construction. Likewise, Defendant only makes scattershot arguments in regard to infringement. For example Nycomed makes the argument that: “All of the '672 Patent claims [have a] limitation ... [requiring] “at least about 80% oleic acid by weight as a fatty acid .... Nycomed intends to make its product with oleic acid that does not have the claims’ requirement of ‘at least about 80% oleic acid.’ ” Opposition Br. 25 (emphasis added). Nycomed’s argument comes absent legal authority and comes absent specificity as to what percentage of oleic acid or superrefined oleic acid Nycomed currently and intends to use in its product. Indeed, Nycomed’s use of the future tense leaves unclear what percentage of oleic acid it currently uses and if that percentage squarely falls within the ambit of Graceway’s claims. Moreover, Graceway has offered persuasive evidence that a cream not using “at least about 80% oleic acid by weight” as a fatty acid would not be stable. Nycomed fails to respond to Plaintiffs’ evidence.
The gravamen of Nycomed’s defense does not relate to non-infringement; rather, it relates to validity, obviousness, enablement, and the written description requirement.
*572
At trial, the burden is on the alleged infringer to show by clear and convincing evidence that the patent is not valid.
See American Hoist & Derrick Co. v. Sowa & Sons, Inc.,
If [] the alleged infringer responds to the preliminary injunction motion by launching an attack on the validity of the patent, the burden is on the challenger to come forward with evidence of invalidity, just as it would be at trial. The patentee, to avoid a conclusion that it is unable to show a likelihood of success, then has the burden of responding with contrary evidence, which of course may include analysis and argument....
While the evidentiary burdens at the preliminary injunction stage track the burdens at trial, importantly the ultimate question before the trial court is different. As this court explained in New England Braiding Co. v. AW. Chesterton Co., the trial court “does not resolve the validity question, but rather must ... make an assessment of the persuasiveness of the challenger’s evidence, recognizing that it is doing so without all evidence that may come out at trial.”970 F.2d 878 , 882-83 (Fed.Cir.1992). Instead of the alleged infringer having to persuade the trial court that the patent is invalid, at this stage it is the patentee, the movant, who must persuade the court that, despite the challenge presented to validity, the patentee nevertheless is likely to succeed at trial on the validity issue.
Thus, when analyzing the likelihood of success factor, the trial court, after considering all the evidence available at this early stage of the litigation, must determine whether it is more likely than not that the challenger will be able to prove at trial, by clear and convincing evidence, that the patent is invalid. We reiterate that the “clear and convincing” standard regarding the challenger’s evidence applies only at trial on the merits, not at the preliminary injunction stage. The fact that, at trial on the merits, the proof of invalidity will require clear and convincing evidence is a consideration for the judge to take into account in assessing the challenger’s case at the preliminary injunction stage; it is not an evidentiary burden to be met preliminarily by the challenger.
Titan Tire Corp. v. Case New Holland, Inc.,
As explained in greater detail below, Plaintiffs are not likely to succeed on the merits because Nycomed has shown a substantial question regarding the validity of the '672 Patent due to obviousness. A claimed invention including a combination of elements is not patentable if it differs from the prior art in a manner “such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art.” 35 U.S.C. § 103(a);
Pfizer, Inc. v. Apotex, Inc.,
Before issuing the '672 Patent, the United States Patent and Trademark Office (“USPTO”) rejected Plaintiffs’ application three times 2 as being obvious over the '994 Wick Patent in view of an extant product specification for super refined oleic acid, (“SROA”). See, e.g., Brown Aff. Exs. M at 4 (second office action), & N. In these rejections, the Examiner indicated that it would have been obvious to use SROA to improve the stability of oleic acid and thus the entire formulation of imiquimod and oleic acid presented in the '994 Patent. Despite various arguments by the applicants against the obviousness of the combination, the Examiner maintained that it was obvious. 3 The Examiner never veered from this finding.
The rejection was finally overcome by a showing of unexpected results in the decreased level of imiquimod-related impurities after combining imiquimod with SROA. But the Examiner offered no explanation, reasoned or otherwise, as to why this showing outweighed the obviousness of the combination using the invention described in the '994 Patent and SROA product specification. See Brown Aff. Ex. 0. Where an examiner does not offer a principled reason for allowance after prior rejections by explaining the balance between the obviousness rejection and the unexpected result described in the allowance, the Court will give less deference to the decision of the USPTO because the Court’s ability to understand the examiner’s decision is limited to the record and reasoning the examiner provides. Here, no reasoning is offered, and as a result, there is little to which the Court can defer.
Nycomed has offered arguments and affidavits in addition to the Examiner’s reasons for initial rejection, to demonstrate the obviousness of the '672 Patent. Nycomed relies primarily on the combination of the Chollet Article, (“Chollet”) (Banker Aff. Ex. C) and an extant SROA product specification, (id. Ex. D) to arrive at the claimed invention. Chollet specifically teaches that oleic acid is the best solubilizing agent of imiquimod, but oleic acid oxidizes in the air, becomes discolored, and turns rancid when heated. Isostearic acid, however, is not as susceptible to oxidation, color change, and rancidity, and isostearic acid has solubilizing properties similar to those of oleic acid. (Banker Aff. Ex. C 39.) Nycomed asserts that SROA’s properties render it an obvious alternative to lessen the disadvantages of regular oleic acid. This is supported by expert testimony tending to establish SROA’s improved stability over oleic acid. (Banker Deck ¶ 33.)
Furthermore, Nycomed has provided testimony that “it is standard practice in the field of pharmaceutical sciences to use the highest grade or purest form of an ingredient when formulating a pharmaceutical product.” (Palmieri Decl. ¶ 5(d).) This position seems sensible. While Plaintiffs argue that the Chollet reference teaches away from the use of oleic acid (because of its inferior properties in relation to oxidation, discoloration, and rancidi *574 ty), it would appear that Chollet actually provides a motivation to test alternatives to improve upon these properties, while still using a better solubilizing agent than isostearic acid. 4 SROA was one such alternative known in the art at the time of this invention. Thus, Nycomed has raised a substantial question as to whether one of ordinary skill in the art at the time of the invention would have had “a reasonable expectation that the substitution of SROA for the oleic acid [described in] the Chollet Article would be successful.” (Palmieri Decl. ¶ 5(d).)
In rebuttal to Nycomed’s obviousness arguments, Plaintiffs have provided evidence of unexpected results. The specification of the '672 Patent states generally that, with the use of SROA, “[surprisingly, the stability of such formulations is substantially greater.” See Patent No. 7,655,672, col. 7, lines 56-58. Nycomed argues that an increase in the stability of the formulation would be expected, especially since oleic acid constitutes the largest component of the formulation other than water. Plaintiffs have clarified that the unexpected result is not a reduction of impurities in general, but a reduction in impurities specific to imiquimod, as shown in Table 2 of the '672 Patent. Plaintiffs support finding unexpectedness by arguing that the reason for the result is unknown. (Brown I Decl. ¶ 17.)
The parties have had a substantial dispute as to the meaning of Table 2 and whether it is indicative of imiquimod impurities alone or impurities of the formulation in general. The statistical reliability of the results is also contested by Nycomed. The Court does not take a position on these issues. For the purpose of this analysis, the Court assumes Plaintiffs are correct, that is, that the results are unexpected. This assumption is consistent with the findings of the Examiner. Additionally, as the Examiner never veered from the finding that the combination of elements itself, considering the '994 Wick Patent and the SROA product specification, would have been obvious, the Court’s finding of obviousness in regard to the combination of elements analysis is also consistent with that of the Examiner. 5 However, as the Examiner provided no reasoning explaining her conclusion in regal'd to her balancing the obviousness of the combination of elements and the unexpected results, the Court is left to perform its own analysis and balancing in regard to weighing the obviousness of the combination with the unexpected results.
Where there is a strong enough showing of obviousness on the record, expert testimony regarding unexpected results may be insufficient to overcome a prima facie case of obviousness.
Pfizer,
As in
In re Eli Lilly,
the prior art here invites experimentation. This is shown in the Chollet article which sought to stabilize imiquimod formulations using solubilizing agents and which also noted that oleic acid was the best solvent discussed. It is highly likely that SROA, as a new, purer product on the market, would have been tested with imiquimod as part of standard industry practice to determine the stability of the formulation. (Palmieri Decl. ¶ 5(d).) As Nycomed has pointed out, one would have expected the use of SROA to increase the overall level of formulation purity.
6
Plaintiffs have not disputed this argument; instead, Plaintiffs rely on the unexpectedness of improvements in regard to imiquimod-related impurities.
7
Thus, Plaintiffs have discovered one specific unexpected property (increased purity of imiquimod) consistent with the more general expected result (increased purity of the formulation as a whole).
See Ex parte Obiaya,
In this case, as in
Pfizer,
there is a strong showing of obviousness, supported
*576
by the Examiner’s three rejections in the prosecution history of the '672 Patent and the evidence provided by Nycomed that the prior art invited experimentation in regard to testing for benefits in regard to stability (of the formulation, as explained by Nycomed, and/or of imiquimod, as explained by Plaintiffs, albeit, while denying any conclusion of obviousness). Plaintiffs have not provided evidence tending to show that the combination of elements would not have been obvious, except for the rebuttal evidence in regard to the unexpected result. While Plaintiffs have shown an unexpected result regarding the reduced level of impurities of imiquimod, the Court, as explained, gives this little relative weight and holds that it is insufficient to overcome the abundant evidence of obviousness. After considering the totality of the arguments and evidence, the Court has determined that Nycomed has made a sufficient showing in regards to obviousness and thus has raised a substantial question regarding the validity of the '672 Patent under the governing legal standard.
See Titan Tire Corp.,
Nycomed also challenges validity based on the written description and enablement requirements. Graceway argues that the '672 Patent meets the written description requirement for validity. “To satisfy the written description requirement, the applicant does not have to utilize any particular form of disclosure to describe the subject matter claimed, but the description must clearly allow persons of ordinary skill in the art to recognize that he or she invented what is claimed. In other words, the applicant must convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention ... and demonstrate that by disclosure in the specification of the patent.”
Carnegie Mellon Univ. v. Hoffmann-La Roche Inc.,
2. Irreparable Harm To Movant If The Injunction Is Not Granted
Lost Sales and Lost Profits.
The Court also notes that in the leading case
*577
awarding injunctive relief for injury to a competitive product which is not protected by the patent in suit, the Court awarded relief because the relevant market was characterized by “design wins.”
Broadcom Corp. v. Qualcomm Inc.,
Plaintiffs argue that damages associated with unit-by-unit lost sales do not compensate for irreparable harm. Indeed, in terms of lost revenue connected to lost sales, determining damages (should it come to that) can be done with greater ease here than in other patent contexts. In the instant litigation, there are only two competitors. A sale captured by Nycomed is likely to be a sale lost to Graceway.
See Eli Lilly & Co. v. Am. Cyanamid Co.,
Price. Graceway claims current and future price erosion. Opening Br. 25 (“Unless enjoined from further infringement, Nycomed will continue to erode the price of Aldara .... This price erosion would be avoided if Nycomed were enjoined and Graceway would be able to begin moving back to the pre-infringement price point.” (emphasis added)). The inference to be drawn from this passage is that Aldara’s price dropped in response to competition. In support of the position stated in its brief, id., Plaintiffs offered the First Moccia Affidavit. But the paragraphs cited in the Moccia Affidavit do not offer any support in regard to Graceway’s price erosion claim. See Opening Br. 24-25.
Nycomed calls Graceway’s representations a “shocking deception” and supplies evidence that Aldara’s price increased. Spadea Aff. ¶ 23 & n. 32 (noting increase in Aldara price from $568 on February 1, 2010 to $738 on April 1, 2010, where Nycomed entered the market on February 25, 2010). Spadea also suggests that this would account for lost unit sales by Graceway. Graceway’s only reply is in a footnote: “Nycomed’s argument that Graceway’s routine annual price increase *578 is evidence of a ‘shocking deception’ ... cannot be taken seriously. The precipitous and continued reduction in Aldara sales after Nycomed’s infringing launch are not attributable to that increase.” Reply Br. 13 n. 7 (citing Moccia 2d Aff. ¶ 5) (emphasis added). It appears that Graceway is not really contesting Nycomed’s point: Graceway’s price for Aldara has not declined, that is, neither the brief nor the Second Moccia Affidavit support the position that any decline has taken place. Graceway’s unwillingness either to put forward evidence in suppox't of its own position or to correct the record is puzzling. Graceway has failed to establish current price ex'osion and has made no substantial argument supported by evidence in regard to expected future price erosion caused by Nycomed’s product. And, the fact that Aldara’s price is now higher, undermines, to some extent, Graceway’s position in regard to lost market share.
Market Share.
Nycomed makes several unsupportable arguments. It claims that Graceway could not have expected exclusive market share at this time because “the '338 [P]atent [covering imiquimod] and its FDA exclusivity expired on February 25, 2010.” But Graceway’s position is that Nycomed’s rival product making use of the '338 Patent, also infringes on the '672 Patent, thereby wrongfully competing with Aldax-a (a product based on the '944 Patent). The expiration of the '338 Patent is not relevant unless Nycomed’s product does not infringe the other two patents— owned by Plaintiffs. Nycomed also argues that Graceway had no reasonable expectation of exclusivity because “generic Aldara substitutes will be permitted” in the not so distant futui'e. The '944 Patent protecting Aldara does not expire until February 2011. Graceway is entitled to exclusivity in regard to the '944 Patent until its lawful right to exclude — based on whatever pat-exits it holds — ends.
See Rite-Hite Corp.,
In
Automated Merch. Sys. v. Crane Co.,
Loss of Jobs.
Graceway puts forward an affidavit stating that “approximately 130 people are being let go.” Musick Aff. ¶ 4; Reply Br. 4 (noting that “more than 40% of Graceway’s 323 em
*579
ployees have been let go”). Musick also indicates that the remaining work force is distracted rather than productive. Nycomed argues: that these changes must have been planned in light of the expiration of Graceway’s patents and is supported only by self-serving affidavits. Graceway responds that its business model planned on only lawful entry into the market by competitors until the '944 Patent expired in 2011. These layoffs arise because that plan was compromised. As to self-serving affidavits, it seems nothing else is possible as only Graceway has the most current relevant information. The Court also has considerable discretion in regard to relying on affidavits, self-serving or otherwise, in the context of a preliminary injunction.
See, e.g., Kos Pharms., Inc. v. Andrx Corp.,
Adequacy of Money
Damages.
10
Nycomed argues that Plaintiffs’ structural claims, including lost jobs, price erosion, market share, and business reputation are compensable by money damages and readily calculable as Aldara is a mature product. For the reasons explained above, this Court agrees. Graceway also argues that the premature termination by (allegedly wrongful) generic competition of its right to exclude from the Aldara market interfered with ongoing business plans on which it relied, thereby blocking socially valuable research and development projects. This Court has held in the patent context that research and development cuts connected to lost revenue caused by infringement are irreparable.
See, e.g., Eisai Co. v. Teva Pharms. USA, Inc.,
Civil Action No. 05-5727,
Lilly contends that the loss of profits on sales of cefaclor because of competition from the appellees will result in irreparable injury to Lilly’s overall pharmaceutical research efforts. As the district court pointed out, however, that claim of injury is not materially different from any claim of injury by a business that is deprived of funds that it could usefully reinvest. If a claim of lost opportunity to conduct research were sufficient to compel a finding of irreparable harm, it is hard to imagine any manufae *580 turer with a research and development program that could not make the same claim and thus be equally entitled to preliminary injunctive relief. Such a rule would convert the “extraordinary” relief of a preliminary injunction into a standard remedy, available whenever the plaintiff has shown a likelihood of success on the merits.
Am. Cyanamid Co.,
In sum, the Court does not find that Plaintiffs have made a sufficient showing in regard to irreparable harm.
3. The Balance Of Hardships Between The Parties
The Court again notes it now has a better developed record.
Plaintiffs repeat much of them irreparable harm argument: unit-by-unit competition and sales loss, loss of its exclusive market share, price erosion (now disputed by the parties), loss of jobs, loss of goodwill, and impairment of future projects. For all these reasons, Plaintiffs argue that money damages are inadequate or “incalculable.” Graceway argues that Nycomed sales far exceed Graceway’s and so Nycomed is better positioned to “absorb temporary loss.”
Nycomed will lose its 180 day period of exclusivity should it not be allowed to continue on the market. But Graceway argues that Nycomed moved forward voluntarily and knowingly after Graceway filed its complaint and so the harm to Nycomed is self-inflicted. Moreover, Nycomed had a seventy-five day post-approval grace period in which to move forward and could have begun negotiations (or arbitration, mediation, or, even, litigation) with Grace-way prior to moving ahead. (Nycomed suggests in a footnote that exercising the 75 day grace period would not have been prudent — and may have led to the loss of the 180 exclusivity period — but no evidence or legal authority for this position is put forward.) Nycomed also argues, as the prior opinion stated, that an injunction now would put at risk its “reputation, its commercial relationships, and, no doubt, on its own employees’ moral[e].” Opposition Br. 26. Nycomed claims it invested heavily to ready launch, but does not specify launch costs apart from more general development costs incurred prior to the approval of the '672 Patent. Id. It claims it would have to lay off employees, but no number is specified. Nycomed’s brief states that its new product is its “biggest generic dermatological product.” Id. But there does not appear to be any evidentiary support for this claim. Nycomed has not been forthcoming.
Although the record on both sides remains somewhat (and surprisingly) vague on these points — Graceway has the better developed record. On balance, this factor leans to Plaintiff Graceway.
4. The Public Interest
The public interest is enhanced by enforcing valid patents: encouraging the development of new drugs through incentives connected to future profits from limited temporal monopolies. The public interest is also enhanced by competition: encouraging generic drugs to come onto the market the moment legal patent protection ends. Both interests are at stake here. These two interests are in equipoise. (The parties’ conduct is also in equipoise.)
*581 Y. CONCLUSION
For the reasons elaborated above, and having weighed the four factors, the Court DENIES Plaintiffs’ Motion for a preliminary injunction.
Notes
. Nycomed's estoppel argument also fails because Nyeomed fails to elucidate any duty to speak that Plaintiff Graceway owed Nycomed — either a duty imposed by law, contract, or connected to the parties' prior course of dealing.
. After a non-final rejection, final rejections were made on May 8, 2009 and August 28, 2009. See Brown Aff. Ex. M.
. Plaintiffs argued that SROA is susceptible to oxidation, that SROA had no prior pharmaceutical applications and would unlikely be chosen by anyone formulating a topical product, and that no one of skill in the art at the time of the invention could predict the stability of a formulation comprising SROA. Each of these three arguments was rejected by the Examiner through a series of Office actions.
.
Cf. Eli Lilly & Co. v. Zenith Goldline Pharms., Inc.,
. It is Plaintiffs' argument that the combination itself is not obvious that is inconsistent with the findings of the Examiner. The Court's position, by contrast, coheres with the Examiner’s position.
. Not only would one have expected an improvement in formulation stability from using SROA, but SROA, in fact, did improve formulation stability. See Patent No. 7,655,672, Summary, col. 2, line 9 (describing “improved formulation stability”); id. Detailed Description, col. 7, lines 56-61.
. While the '672 Patent itself states that the increased stability of the overall formulation is unexpected, Plaintiffs have clarified that "the unexpected result of the '672 Patent is not that the impurities in general were reduced, but that imiquimod impurities were also reduced.” Plaintiffs’ Br. 36 (emphasis in original).
. Because the Court has held that it is unlikely that Plaintiffs will establish infringement (given the obviousness defense), the Court need not address whether a presumption of irreparable harm flows automatically from a finding of infringement.
