MEMORANDUM
I. INTRODUCTION
Plaintiff, U-Fuel, Inc. (“U-Fuel” or “plaintiff’) alleges in this patent infringement action that Highland Tank & Manufacturing Company, Inc. (“Highland”), Steel Tank Institute (“STI”), and Modern Welding Company of Ohio, Inc. (“Modern”) (collectively, “defendants”) infringed U-Fuel’s United States Reissued Patent No. 37,144 (the “'144 patent”) by licensing, manufacturing, and selling non-insulated, above-ground storage tanks (“ASTs”) and marketing such tanks as “fire-resistant.” U-Fuel, Highland, and Modern manufacture and sell ASTs. STI is a non-profit trade association whose members include AST manufacturers. STI’s purpose is to promote the use of high-quality steel tanks which are manufactured by its members to meet fire codes and environmental regulations.
Presently before the Court is plaintiffs Motion for a Preliminary Injunction (Document No. 3, filed May 9, 2002), in which plaintiff seeks an order barring defendants from marketing, selling, offering for sale, distributing, licensing, manufacturing, or using any non-insulated, “fire-resistant” ASTs which infringe the '144 patent. Defendants respond by asserting a number of defenses' — prior art inherently anticipates the '144 patent; plaintiffs claim construction violates the written description requirement of 35 U.S.C. § 112; the allegedly infringing activities of defendants are protected under the intervening rights provision of 35 U.S.C. § 252; plaintiff failed to disclose the best mode in making “fire-resistant” ASTs; inconsistent testimony by plaintiff evidences unclean hands; and plaintiff procured the '144 patent through inequitable conduct — warranting the denial of plaintiffs motion.
For the reasons set forth in this Memorandum, plaintiffs Motion for a Preliminary Injunction is denied.
II. PROCEDURAL HISTORY
U-Fuel filed a Complaint against defendants on May 7, 2002. The Motion for a Preliminary Injunction was filed on May 9, 2002. Defendants responded on June 13, 2002; plaintiff filed a reply on July 17, 2002.
The Court held a hearing on the Motion for a Preliminary Injunction on July 22 through 25, 2002, and granted the parties leave to file supplemental memoranda on the issue of the validity of the reissued '144 patent. Both parties thereafter filed supplemental memoranda. The motion was fully briefed on September 9, 2002.
*599 The Court will now set forth findings of fact and conclusions of law in ruling on plaintiffs Motion for a Preliminary Injunction based on evidence presented at the hearing and the written submissions of the parties.
III. FINDINGS OF FACT
ASTs are used for industrial and commercial purposes to store combustible and flammable liquids such as gasoline. Because of the inherent safety risks that ASTs pose, private and public entities have promulgated standards for the testing and rating of ASTs. Such private entities include Underwriter’s Laboratories, Inc. (“UL”), the National Fire Protection Association (“NFPA”), and Southwest Research Institute (“SwRI”).
The “Standard for Steel Aboveground Tanks for Flammable And Combustible Liquids” (“UL 142”) was created in 1922 by UL and prescribes the' minimum construction standard for single and double wall ASTs. 1 Due to increased demand for ASTs for storing commercial fuel, 2 UL developed an additional performance-based listing, known as the “Standard for Insulated Aboveground Tanks for Flammable and Combustible Liquids” (“UL 2085”), 3 which tested the internal temperature rise of insulated ASTs when subject to an external temperature of 2000 degrees Fahrenheit for not less than two (2) hours. Insulated ASTs are listed as “protected” under UL 2085 if the increase in internal temperature does not exceed 400 degrees Fahrenheit. Non-insulated ASTs are not tested under the UL 2085 standard.
The NFPA is an organization which periodically publishes fire codes and safety use requirements, such as separation distances between an AST and a building, an AST and a public roadway or other property line, and an AST and a fuel dispenser. Defs.’ Ex. 8. Section 2-4.5 of the NFPA 30A, Automotive and Marine Service Station Code (“NFPA 30A”), created the standard for “fire-resistant tanks.” 4 Under Section 2-4.5(a), an AST is listed -as “fire-resistant” if it prevents: (a) the release of liquid; (b) failure of the supports for the tank; and (c) impairment of venting for two (2) hours when tested using “a fire exposure that simulates a high-intensity pool fire, such as that described in UL 2085 ... or equivalent test procedure.” Section 2-4.5(a), NFPA 30A (1996).
In' the late 1980’s and early 1990’s, double wall, non-insulated tanks, constructed in accordance with UL 142, were manufactured and sold as ASTs. 5 These ASTs were non-insulated in that the space between the primary and secondary tank was not filled with insulation (usually a concrete mixture) and they were capable of being monitored for any leakage into this space. Non-insulated ASTs are lighter than insulated tanks and thus more mobile and easier to transport. Testimony of R. Michael Webb, July 23, 2002, at 92. In addition, *600 non-insulated tanks cost approximately fifty percent less than insulated tanks. Testimony of Charles A. Frey, July 24, 2002, at 41-42, 45.
In 1993, STI published the “Standard for Aboveground Tanks With Integral Secondary Containment” (“F921”), a specification standard for double wall, non-insulated tanks made in accordance with UL 142. PL’s Ex. 35. Thousands of ASTs manufactured to this standard were sold by STI members during the 1993-1995 period. Defs.’ Ex. 8. Highland and Modern each sold their own versions of double-wall, non-insulated tanks that conformed to UL 142 during this time period as well. Defs.’ Ex. 9; Defs.’ Ex. 10.
U-Fuel filed a patent application on January 17, 1996 covering the construction of an “improved” AST “fabricated from steel plates of minimum thickness, the sheets being made from a special metal alloy, and the plates welded in a specific way, in order to withstand a 2000"F. environment for a minimum of two hours.” (U.S. Patent No. 5,723,842 (the “'842 patent”), column 2, lines 41-44). The '842 patent was issued by the Patent Office on March 3,1998.
SwRI is an applied research and development non-profit organization which provides standards and protocols for the testing, listing, and labeling of tanks, including ASTs. In 1995, U-Fuel contracted with SwRI to create a testing protocol for its non-insulated ASTs. In the context of the contractual arrangement between U-Fuel and SwRI, U-Fuel’s President R. Michael Webb (“Mr.Webb”) persuaded SwRI to adopt a testing protocol with no internal temperature limits on the ground that Section 2-4.5 of NFPA 30A imposed no requirements for maximum internal temperature rise in its definition of “fire-resistant.” This led to the development of testing protocol 97-04 (“SwRI 97-04”) in 1997. SwRI 97-04, a high-intensity fire exposure, leakage, and hose stream test, provided a new standard for the industry to test whether a non-insulated AST met the fire-resistant requirements of NFPA 30A; i.e., listed as able to withstand an environment of 2000 "F. for two hours without sustaining any welding failure or leakage. Prior to SwRI 97-04, only tanks containing insulation could meet the internal temperature requirements of UL 2085 and thus be considered “fire-resistant” pursuant to NFPA 30A.
SwRI began testing U-Fuel’s tanks pursuant to SwRI 97-04 on April 15-16, 1999. Due to industry-wide acceptance of SwRI 97-04, other tank manufacturers and organizations contacted SwRI to have their ASTs tested for labeling and listing under this protocol. STI contracted with SwRI to conduct an SwRI 97-04 test on one of its F921 tanks. On May 13, 1999, STI publicly announced that its F921 tank passed the SwRI 97-04 protocol. Thereafter, STI adopted the trade name “Flam-eshield” for its F921 tanks. On November 21, 1999, STI issued a press release reporting that its Board of Directors had authorized the “Flameshield” program and that its members could officially begin marketing “Flameshield” tanks in early 2000. Defs.’ Ex. 22. Accordingly, members of STI, including Highland and Modern, began manufacturing and selling “Flameshield” tanks in early 2000 and continue to do so today. “Flameshield” tanks are listed as “fire-resistant” under NFPA 30A and are marketed as such.
After learning about the successful SwRI 97-04 test of STI’s F921 tank, U-Fuel notified SwRI that the SwRI 97-04 testing and certification of tanks of U-Fuel’s “competitors” conflicted with U-Fuel’s original '842 patent. Mr. Webb sent a letter to Gladys Finley of SwRI, dated July 15, 1999, stating that U-Fuel “underst[ood] that Southwest Research In *601 stitute has tested and certified other tanks for our competitors as being Fire Resistant under Test Procedure 97-04. It is [our attorneys’] opinion that U-Fuel owns this technology and that it is unlikely that Southwest Research Institute could perform certification without conflicting with U-Fuel’s ['842] Patent ...” Defs.’ Ex. 57.
U-Fuel then filed suit against SwRI on May 3, 2000, alleging, inter alia, misappropriation of trade secrets; that SwRI wrongfully disclosed to third parties proprietary and confidential information relating to the technology U-Fuel used in the manufacture of its non-insulated ASTs. See U-Fuel, Inc. v. Southwest Research Institute, CA. No. 00-480 (W.D.Tex. Dec. 3, 2001). Specifically, U-Fuel contended that SwRI disclosed information (obtained through U-Fuel’s production manual obtained as part of its contractual arrangement with SwRI, and during SwRI’s on-site inspections of U-Fuel’s manufacturing plants) to U-Fuel’s competitors, such as STI, so that they in turn could directly manufacture “fire-resistant” ASTs and become clients of SwRI without entering into licensing agreements with U-Fuel. Id. at 3.
On December 3, 2001, the magistrate judge in the SwRI suit recommended that SwRI’s motion for summary judgment with regard to the trade secret misappropriation claims be granted because U-Fuel failed to establish that SwRI wrongfully divulged to third parties any confidential or proprietary information received from U-Fuel; the magistrate judge concluded that it was undisputed that U-Fuel had already provided the same information to third parties and thus, SwRI did not make any “unauthorized” disclosures of U-Fuel’s confidential or proprietary information. Id. The district court accepted the magistrate judge’s recommendation by order dated January 31, 2002. Defs.’ Ex. 17.
Prior to the suit against SwRI, U-Fuel filed a reissue patent application on January 24, 2000, which contained the original claims from the '842 patent and additional method claims specifically referencing non-insulated fire-resistant ASTs. U-Fuel sought a reissued patent on the ground that the original '842 patent was “overly specific” and “partly inoperative because [U-Fuel] claimed less than [it was] entitled to claim.” Defs.’ Ex. 4; see also Testimony of R. Michael Webb, July 23, 2002, Hearing Tr. at 186. The Patent Examiner originally rejected U-Fuel’s additional claims in view of the two UL standards, UL 142 and UL 2085. However, after an interview with representatives of U-Fuel, the Examiner allowed the new claims on the basis that such claims were to be limited to “non-insulated” ASTs, mistakenly noting that the UL standards were for “insulated tanks” only. Defs.’ Ex. 6. 6 The Patent Office issued the '144 patent to U-Fuel on April 24, 2001.
On April 30, 2001, Mr. Webb sent a copy of the '144 patent to Wayne Geyer of STI and offered STI a license under the '144 patent. PL’s Ex. 15. In May 2001, Mr. Webb and Mr. Geyer discussed the possibility of a license agreement. Mr. Geyer informed Mr. Webb in this conversation that STI’s Board of Directors would consider U-Fuel’s proposal. Testimony of Mr. Geyer, July 23, 2002, Hearing Tr. at 76-77. There was, however, no further contact between the parties regarding U-Fuel’s licensing offer. Nevertheless, U- *602 Fuel delayed initiating the present patent infringement action until May 7, 2002.
For purposes of plaintiffs Motion for a Preliminary Injunction, plaintiff proceeds on only one of claims set forth in the '144 patent, Claim 27. Claim 27 is a method claim — a claim which is not tied to a particular device, but is a series of steps that are performed to transform materials to a “different state or thing.”
Schumer v. Lab. Computer Sys., Inc.,
A method of making a noninsulated above-ground fire-resistant storage tank for storing combustible material such as gasoline, comprising steps of:
(a) providing a plurality of sheet steel pieces having a composition, each of said sheet steel pieces having a minimum thickness;
(b) assembling and welding the sheet steel pieces into joints with at least one weld metal to form a storage tank; and
(c) installing at least fitting on the storage tank; and wherein the configuration of said joints, the composition and thickness of said sheet steel pieces and the composition of the weld metal are selected and combined such that the storage tank is able to withstand an environment of at least 2000 degrees F. for a period of time of at least two hours.
IV. CONCLUSIONS OF LAW AND DISCUSSION
A. Standard of Review
To obtain a preliminary injunction the moving party must establish that: “(1) it has a reasonable likelihood of succeeding on the merits; (2) it will suffer irreparable harm if the injunction is not granted; (3) the balance of hardships tips in its favor; and (4) an injunction would be consistent with the public interest.”
Helifix Ltd. v. Blok-Lok, Ltd.,
In order to demonstrate a likelihood of success on the merits, U-Fuel must show that, in light of the presumptions and burdens at trial on the merits, (1) U-Fuel will likely prove that defendants infringe the '144 patent, and (2) U-Fuel’s infringement claim will likely withstand defendants’ challenges to validity and enforceability of the '144 patent.
Genentech, Inc. v. Novo Nordisk, A/S,
If a defendant raises a substantial question concerning validity,
ie.,
asserts an invalidity defense that a plaintiff cannot prove “lacks substantial merit,” a preliminary injunction will not issue.

B. Claim Construction
The parties dispute the construction of Claim 27’s phrase “selected and combined such that the storage tank is able to withstand an environment of at least 2000 degrees F. for a period of time of at least two hours.” Specifically, they disagree as to the significance and construction of the terms “selected and combined.” U-Fuel argues that these terms distinguish Claim 27 from prior art in that they necessarily entail an intent to build a tank that is “fire-resistant.” Defendants dispute plaintiffs construction, asserting that there is no such intent limitation attached to these terms.
The “first step” of an invalidity analysis based on anticipation in view of prior art is determining the claim’s meaning and scope.
See Lemelson v. Gen. Mills, Inc.,
In construing the meaning and scope of a claim, the Court can consider two types of evidence: intrinsic and extrinsic. Vi-
tronics Corp. v. Conceptronic, Inc.,
In considering intrinsic evidence, the Court must look first to the claim language itself to define the scope of the protected invention.
Bell Atlantic Network Servs., Inc. v. Covad Communications Group, Inc.,
U-Fuel contends that the language “selected and combined” instructs one skilled in the art to select and combine materials with the intent of manufacturing a non-insulated AST that can withstand a 2000 degree Fahrenheit environment for two hours. U-Fuel argues that the words “selected and combined” necessarily incorporates an “intent” limitation — a limitation that U-Fuel notes is neither in the UL 142 standard nor the F921 specifications' — • thereby distinguishing its claim from prior art. Defendants dispute this construction and assert that there is no intent element in Claim 27 that makes this process claim new.
*604
To support its interpretation that the terms “selected and combined” embody an “intent-to-achieve-fire-resistance” limitation, U-Fuel cites two cases,
Nat’l Recovery Techs., Inc. v. Magnetic Separation Sys., Inc.,
Although Nat’l Recovery and Optical Coating both involved the disputed construction of the term “select” in method claims, that is where the similarity to the present case ends. Those cases never addressed the issue of whether the plain and ordinary meaning of the term “select” to one of ordinary skill in the art includes the intent of achieving an objective for the purpose of distinguishing a claim from pri- or art. In other words, the courts in these cases were not faced with the question of whether an intent limitation is attached to the term “select” to prevent prior art anticipation, nor did they in fact conclude that this term incorporates such an intent element.
The dispute in Nat’l Recovery centered around whether the term “select” merely stated a preference for certain radiation signals that did not pass through plastic containers or required “perfect isolation” between those signals that passed and those that did not pass. That case did not address the question presented in this case — whether the term “select” incorporated an intent limitation. In Optical Coating, the crux of the controversy was whether two distinct processes of applying protective films to optical lenses was incorporated in the term “select,” not whether this term included an intent limitation.
Moreover, an argument of claim construction similar to that made by U-Fuel was rejected in
In re Cruciferous Sprout Patent Litigation,
In construing a claim, the “claim terms are to be given their ordinary meaning unless it is apparent that the inventor intended to use them differently.” Nat’l
Recovery,
The Court notes that for purposes of plaintiffs motion, its construction of Claim 27, in particular the terms “selected and combined,” is a tentative one. The Court is not required to interpret Claim 27 “conclusively and finally” when deciding a motion for preliminary injunction.
Sofamor Danek Group, Inc. v. DePuy-Motech, Inc.,
C. Likelihood of Success on the Merits: The Validity of Claim 27
In defense of its “Flameshield” tanks, defendants assert, inter alia, that the '144 patent and Claim 27 are invalid based on prior art. Specifically, they contend that the F921 tank and other double wall, non-insulated ASTs manufactured and sold more than one year prior to the filing of U-Fuel’s application of the '842 patent on January 17, 1996, 8 anticipated U-Fuel’s reissued '144 patent. Further, defendants argue that the “Flameshield” tank is identical to the F921 tank. Defendants contend that they have been “selecting and combining” steel and joints in the assembly of their ASTs in the same way today as they did prior to the critical date; that there has been no change in the manufacturing processes of their double wall, non-insulated ASTs, now labeled “Flamesh-ield,” since the F921 tanks were first sold to the public prior to the critical date. Hearing Tr., July 24, 2002, at 34-35.
U-Fuel counters by highlighting the fact that the “Flameshield” 2001 specifications have grown in size from the pre-critical *606 date F921 specifications 9 and that the “carbon equivalency” formula has changed. Pl.’s Ex. 54. However, these changes, including the carbon equivalency formula, were global; they were applied to all of STI’s above-ground and underground tank technologies. Testimony of Laurie Grai-nawi, July 25, 2002, at 22-24. Moreover, although the “Flameshield” specification is more lengthy and includes much material not in the F921 specification, 10 the changes did not affect the process — selection of steel and thickness used, the type of joints, and the method of welding — in which defendants’ non-insulated ASTs were manufactured prior to the critical date. Id. at 25.
Based on the evidence submitted by Highland and Modern the Court agrees with defendants and concludes that their non-insulated ASTs made prior to the critical date were manufactured in the same way that the “Flameshield” tanks are manufactured today. Testimony of Charles A. Frey, July 24, 2002, at 12-20; Defs.’ Ex. 32-42; Testimony of Jerry L. Waller, July 24, 2002, Stipulation Of Parties, ¶ 2; Testimony of Messrs. Larry O’Shea and Duane Hazelwood, Stipulations Of Parties, ¶ 4.
U-Fuel argues that even if the terms “selected and combined” do not embody the intent to pass a fire-resistance test, and that Claim 27 was a manufacturing process known to defendants prior to the critical date, Claim 27 is still valid because it is a “new use” of a known process' — the “new use” of being an AST that is not insulated, and yet capable of being listed as “fire-resistant” under NFPA 30A 11 — and thus, patentable under 35 U.S.C. § 101 12 and 35 U.S.C. 100(b). 13 A certified “fire-resistant” AST, U-Fuel claims, can be put to “new uses” for which an AST not so labeled could not be utilized under Section 1-1.1. of NFPA 30A.
In response to plaintiffs “new use” contention, defendants argue that method Claim 27 simply describes an old use, anticipated by prior art, and is not patentable. They assert that “fire-resistance” is an inherent feature of their pre-critical date ASTs and the fact that a non-insulated AST can currently be labeled as “fire-resistant” is merely a result of a new fire standard, SwRI 97-04, and nothing more. Indeed, the only development that can be considered “new,” according to defendants, is the SwRI 97-04 protocol, not Claim 27. Defendants also argue that the use of ASTs has always been the same' — to store combustible and flammable materials; the only use actually recited in Claim 27.
Defendants have also raised the following defenses to the validity and enforcement of the '144 patent: (1) Claim 27, as construed by U-Fuel to broadly cover steel, thickness, and weld joints other than *607 those expressed in the patent specification, violates the written description requirement of 35 U.S.C. § 112, which mandates that a patent specification must clearly allow those skilled in the art to recognize what is claimed; (2) there is no evidence that defendants were infringing any claims of the original, and now surrendered, '842 patent, and defendants’ allegedly infringing activities conducted prior to the reissuance of the '144 patent are protected under the “intervening rights” provision of 35 U.S.C. § 252, which provides that third parties may continue to manufacture infringing products where substantial preparation was made before the grant of a reissued patent; (3) Mr. Webb, the inventor of the '144 patent and U-Fuel’s president, violated the requirement of disclosing the “best mode” for making a fire-resistant AST; (4) conflicting testimony of Mr. Webb in the Texas trade secret action and the preliminary injunction hearing in this case demonstrates U-Fuel’s “unclean hands”; and (5) plaintiffs “inequitable conduct” in procuring the '144 patent by failing to correct the Patent Examiner’s mistaken belief that the UL standards applied only to insulated tanks.
For the reasons set forth below, the Court concludes on the present state of the record that U-Fuel’s method claim is inherently anticipated by defendants’ prior art and is thus invalid. Accordingly, the Court need not address defendants’ other defenses to plaintiffs motion.
New uses of known processes may be patentable, see 35 U.S.C. § 101 (“Whoever invents or discovers any new and useful process ... may obtain a patent therefor.”); 35 U.S.C. § 100(b) (“The term ‘process’ means process, art or method, and includes a new use of a known process, machine, manufacture, composition of matter, or material.”), provided that the new use is new and is not anticipated by prior art.
See
35 U.S.C. § 102(b) (stating that a patent is invalid as anticipated if the claimed invention “was patented or described in a printed publication in this or a foreign country or in public use or on sale in the country, more than one year prior to the date of application for patent in the United States”). An anticipation analysis involves a comparison of the claim, as construed, to the prior art.

However, “a prior art reference may anticipate when the claim limitation or limitations not expressly found in that reference are nonetheless inherent in it.”

tic — fire-resistance—of a known method— manufacturing non-insulated ASTs — directed to the same purpose — storing combustible and flammable materials. Therefore, although in appropriate cases a court is instructed to construe claims so as to preserve their validity,
Wang Labs., Inc. v. Am. Online, Inc.,
It is of no import that the non-insulated ASTs manufactured by defendants were not marketed as “fire-resistant” until the introduction of SwRI 97-04. Indeed, the only performance test in existence one year prior to the critical date was the UL 2085 test and no non-insulated AST, regardless of the manufacturer, could pass that test and be characterized as “fire-resistant” pursuant to NFPA 30A. Although U-Fuel may have been the first to persuade the tank industry that non-insulated ASTs could be certified as fire-resistant if they were to undergo a different performance test, i.e., one that does not have internal temperature requirements, it cannot patent the newly-disclosed results of that test.
To support its contention that the method claim is a new use not anticipated by prior art, U-Fuel relies on
In re Zierden,
The court in Zierden found the composition claim, distinguishable only by the intended use in the claim — the removal of alluvium deposits — unpatentable, holding that a “mere statement of a new use for an otherwise old or obvious composition cannot render a claim to the composition patentable.” Id. at 1328. However, the court also held that the method claim was not anticipated by prior art because the purpose of removing alluvium was a limitation on the claim. The court determined that *610 (1) the term “water systems” contained in the claim language must be read as a claim limitation that the “water systems contained alluvium;” and (2) there was nothing in the record that the water systems in the prior art contained alluvium or that its presence was contemplated. Id. at 1331. As such, the Zierden court concluded that alluvium removal was not an inherent characteristic of the composition and thus ruled that the process, as claimed, was not anticipated by prior art. Id:
In the instant case, however, the intended purpose of the prior art and U-Fuel’s patented process, as claimed, is the same — storing combustible and flammable materials such as gasoline. If Claim 27 patented a process of building a non-insulated AST for use in storing drinking water, Zierden would be apposite. In that scenario, while both the prior art and the patented process involve the building of a non-insulated AST — -just as both the prior art and the patented process in Zierden involved using a potassium composition to treat water systems — the intended use of the prior art (storing combustible materials) and the intended new use of the patented process (storing ■ drinking water) is distinguishable — -just as the intended use of the prior art in Zierden (removing scale deposits) and the intended new use of the patented process (removing suspended alluvium) is distinguishable.
A hypothetical set forth in
Catalina Marketing Int’l, Inc. v. Coolsavings.com, Inc.,
Inventor A invents a shoe polish for shining shoes (which, for the sake of example, is novel, useful, and nonobvious). Inventor A receives a patent having composition claims for shoe polish. Indeed, the preamble of these hypothetical claims recites “a composition for polishing shoes.”... Inventor B, could not secure claims on the method of using the composition for shining shoes because the use is not a “new use” of the composition but, rather, the same use of shining shoes ... (citations omitted) ... Suppose Inventor B discovers that the polish also repels water when rubbed onto shoes. Inventor B could not likely claim a method of using the polish to repel water on shoes because repelling water is inherent in the normal use of the polish to shine shoes ... (citations omitted) ... In other words, Inventor B has not invented a “new” use by rubbing polish on shoes to repel water. Upon discovering, however, that the polish composition grows hair when rubbed on bare human skin, Inventor B can likely obtain method claims directed to the new use of the composition to grow hair. Id. at 809-810.
U-Fuel’s attempt to claim a method of building non-insulated ASTs that are also fire-resistant is analogous to Inventor B’s unsuccessful attempt to claim a method of using shoe polish to repel water. The normal use of non-insulated ASTs in both the prior art and U-Fuel’s claim is to store combustible materials, just as the normal use of polish for Inventor A and Inventor B is to shine shoes. Fire-resistance is an inherent property of the non-insulated ASTs when used for the purpose of storing combustible materials, just as the repelling of water is an inherent property of the polish when used to shine shoes.
See, e.g., In re King,
In both Claim 27 and prior art, the same purpose — storing combustible and flammable materials — is claimed. The only difference between U-Fuel’s claim and prior art is the newly-disclosed “benefit” of fire-resistance (the result of a new testing protocol, and not the result of any new technology or methodology), a difference that does not render U-Fuel’s claimed process patentable. Accordingly, for all of the above reasons, the Court concludes on the present state of the record that defendants have successfully raised a substantial question as to the validity of U-Fuel’s reissued '144 patent. 15 Therefore, U-Fuel has not demonstrated a likelihood of success on the merits.
D. Irreparable Harm
The second factor a party must establish in order to obtain a preliminary injunction is that it will suffer irreparable harm if the preliminary injunction is not granted. U-Fuel asserts that if defendants are not preliminary enjoined from their current activities, U-Fuel will no longer be able to continue licensing its technology, thereby preventing U-Fuel from establishing a strong domestic market presence as a li-censor in the fuel storage tank industry. U-Fuel also claims that if its patent goes unprotected, it will lose the right to exploit its patent altogether. The Court is not convinced by U-Fuel’s argument.
A presumption of irreparable harm will arise where the patentee has made a clear showing of patent validity and infringement.
Amazon.com,
In its analysis of irreparable harm in a patent case, a court can consider the period of delay exercised by a party prior to seeking a preliminary injunction.
See Hybritech Inc. v. Abbott Labs.,
To explain this delay in seeking injunc-tive relief, U-Fuel contends that Claim 27 was not in the original '842 patent. Although Claim 27 was not in the original '842 patent, and is the only claim asserted for purposes of U-Fuel’s Motion for a Preliminary Injunction, U-Fuel still alleges, in the motion, that defendants’ “Flam-eshield” tanks infringed Claims 1 and 3 of the reissued '144 patent, which are identical to Claims 1 and 3 in the original '842 patent. In this regard, U-Fuel provides no adequate explanation why it could not have sought injunctive relief against defendants based on the alleged infringement of Claims 1 and 3 in the '842 patent when STI unveiled its “Flameshield” program to the public in late 1999 or why it did not act to protect its '842 patent when U-Fuel learned about SwRI’s testing activities in July of 1999.
U-Fuel also argues that its delay is attributable to a trade secret action against SwRI in Texas. U-Fuel claims that because it was involved in this expensive, out-of-state litigation, it could not afford to simultaneously litigate the present dispute. However, U-Fuel fails to explain why it chose to delay bringing suit on its original '842 patent or why it decided to proceed with the trade secret litigation against SwRI, a non-competitor of U-Fuel, instead of proceeding with a patent infringement suit against its competitors in the tank industry.
Finally, U-Fuel asserts that its delay was due, in part, to STI’s failure to timely respond to U-Fuel’s offer to license its technology immediately upon the re-issuance of the '144 patent on April 24, 2002. On April 30, 2001, U-Fuel contacted STI offering a license under the '144 patent. Pl.’s Ex. 15. The two parties discussed the licensing proposal in May 2001, but STI decided not to respond to U-Fuel’s offer and there was no further contact between the parties regarding a licensing agreement. To explain its delay U-Fuel says it patiently waited for a response from STI that never came. The Court finds this explanation unpersuasive. In fact, U-Fuel’s attempt to license its patent to STI cuts against its argument that it will suffer irreparable harm.
In addressing the issue of irreparable harm, the Court must determine whether money damages are sufficient to compensate plaintiff. Not only is U-Fuel’s attempt to license its patent to defendants (and delay in seeking injunctive relief) incompatible with the right to exclude and exploit a patent,
see T.J. Smith & Nephew Ltd. v. Consolidated Med. Equip., Inc.,
For the foregoing reasons, the Court concludes that U-Fuel has not shown that it will suffer irreparable harm if the preliminary injunction is denied.
V. CONCLUSION
Defendants have raised a substantial question as to the validity of the '144 patent based on anticipation of prior art on the present state of the record. Moreover, by its delay in seeking injunctive relief and its attempt to license the '144 patent to STI, U-Fuel has failed to demonstrate irreparable harm. Therefore, the first two requirements for a preliminary injunction have not been met, and the Court denies plaintiffs Motion for a Preliminary Injunction. 17
An appropriate order follows.
ORDER
AND NOW, this 4th day of November, 2002, upon consideration of Plaintiffs Motion for a Preliminary Injunction and Expedited Discovery (Document No. 3, filed May 9, 2002), and the related submissions of the parties, following a hearing on July 22 through 25, 2002, for the reasons set forth in the attached Memorandum, IT IS ORDERED that plaintiffs Motion for a Preliminary Injunction and Expedited Discovery is DENIED.
Notes
. UL 142 is a construction standard, not a standard for "fire-resistance.” The construction standard for a double-wall tank was first included in the seventh edition of UL 142, published in 1993. Defs.’Ex. 81.
. The demand for ASTs significantly increased after the Environmental Protection Agency finalized its underground storage tank requirements in 1988. Defs.' Ex. 8.
. The first issue of UL 2085 was published in 1992. PL’s Ex. 44.
. "[NFPA 30A] shall apply to automotive service stations, marine service stations, service stations located inside buildings, and fleet vehicle service stations.” Section 1-1.1, NFPA 30A (1996). Only those tanks that are listed as "fire-resistant” under Section 2-4.5(a) can be used in the areas designated under Section 1-1.1.
. Brown Minneapolis Tank began making and selling double wall, non-insulated ASTs in 1988. These tanks received a UL 142 listing shortly thereafter. Defs.’Ex. 10.
. In the interview summary with representatives of U-Fuel, the Examiner recommended that U-Fuel amend its "independent claims to specify a non-insulated ground fire-resistant storage tank” and "discuss the applied prior art in this light,” and noted that "the UL standards are for insulated tanks.” Interview Summary, Patent Examiner Clifford Shaw, August 23, 2000.
. Section 282 provides, in pertinent part, as follows: "A patent shall be presumed valid ... The burden of establishing invalidity of a patent or any claim thereof shall rest on the party asserting it.”
. The one-year-prior date is referred to as the “critical date." In the Court’s determination of whether prior art anticipated U-Fuel's '144 reissued patent, January 17, 1995 is the critical date because U-Fuel applied for its original '842 patent on January 17, 1996. See, e.g., 35 U.S.C. § 102(b) (stating that a patent is invalid as anticipated if the claimed invention "was patented or described in a printed publication in this or a foreign country or in public use or on sale in the country, more than one year prior to the date of application for patent in the United States”).
. STI’s F921 specifications pre-critical date was 14 pages. Pl.’s Ex. 35. STI's ''Flamesh-ield” 2001 specification is 67 pages. Pl.’s Ex. 39.
. Defendants assert, and plaintiff's do not dispute, that most of the increase made in the "Flameshield” specification included material set forth previously in stand-alone documents, such as UL 142 and dike-design standards. Pl.'s Ex. 39, Appendices B, D, and F.
. The Court notes that NFPA 30A is not mentioned anywhere in the reissued '144 patent.
. 35 U.S.C. § 101 provides: "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor. ...”
. 35 U.S.C. § 100(b) defines the term "process” as a "process, art or method, and includes a new use of a known process, machine, manufacture, composition of matter, or material.”
. Although the claim at issue here is a method claim,

is applicable even though that case involved a composition claim.
See In re Cruciferous,
. At this preliminary injunction stage, the Court does not completely resolve the validity question. Actual validity is the issue at trial.
