BYE, Circuit Judge.
Sensient Flavors appeals the district court’s1 grant of summary judgment in favor of SensoryEffects Flavor Company, formerly known as SensoryFlavors. On appeal, Sensient Flavors contends the district court erred in concluding the SensoryFlavors mark was not “used in commerce” as defined by the Lanham Act, 15 U.S.C. § 1127. Sensient Flavors also asserts the district court erroneously held the SensoryEffects Flavor Company name was not likely to cause confusion to customers. Finally, Sensient Flavors argues the district court erred by holding its mark was “relatively weak” and not entitled to protection under the Missouri dilution statute. We affirm the district court’s grant of summary judgment.
I
Sensient Technologies Corporation (“Sensient”) sells flavor delivery systems to its customers. Since 2000, Sensient has continuously used the trade name Sensient Flavors, among its other trademarks. The mark appears on communications from Sensient Flavors, including advertising and marketing materials, business cards, letterheads and invoices.
Charles Nicolais, a former employee of Sensient Flavors’ sister company Sensient Colors, Inc., left the company to start his own business called Performance Chemicals and Ingredients, LLC (“PCI”). In May 2006, PCI purchased substantially all of the assets of Diehl Food Ingredients, Inc. (“Diehl”). In November 2006, PCI also purchased substantially all of the assets, equipment, trademarks and trade names of SensoryEffects, a business engaged in development, manufacture, and sales of lipid-based flavor delivery systems. The prior owners of SensoryEffects had filed an application for the registration of the SensoryEffects name and graphic in July 2004, which was formally registered by the United States Patent and Trademark Office (“PTO”) on July 3, 2007. PCI further expanded its operations in February 2008 by acquiring Givaudan Flavors, Inc., the dairy flavor systems business within Givaudan Flavors Corporation. As [759]*759part of the purchase agreement, PCI was not permitted to use the Givaudan Flavors trade name for more than sixty days after the purchase.
After the purchase of Givaudan Flavors, Nicolais undertook the responsibility of choosing a new name and brand for the business. Ultimately, the company decided to use the name SensoryFlavors, Inc., building on the SensoryEffects trademark already in use. As part of this process, SensoryFlavors modified the existing SensoryEffects mark to design the new SensoryFlavors mark. The company’s attorneys informed Nicolais the SensoryFlavors name was available for use and registration based on a search of PTO records and corporate names. However, the parties dispute the knowledge Nicolais maintained regarding the existence of the Sensient Flavors name at the time he was choosing the new name. Although he was previously employed by Sensient Colors, Nicolais asserts he never worked for Sensient’s flavor group and therefore he was not aware of the Sensient Flavors mark before the lawsuit was filed. Thus, he contends the Sensient Flavors name did not cross his mind while choosing the SensoryFlavors name. Sensient Flavors disputes Nicolais’s assertion, noting that a document drafted by one of PCI’s employees prior to the purchase of the Givaudan business unit lists Sensient Flavors as one of SensoryFlavors’ primary competitors.
On the day the Givaudan purchase was finalized, SensoryFlavors sent an announcement to contacts in the food ingredients industry featuring the SensoryFlavors mark. SensoryFlavors and Givaudan also sent a media release announcing the acquisition, which included the SensoryFlavors mark. SensoryFlavors asserts it only gave two presentations to customers after acquiring Givaudan Flavors on February 13, 2008, both of which occurred prior to the instant suit. Moreover, SensoryFlavors contends no sales were made under the new mark, no packages were sent bearing labels with the new mark, and no goods were transported under the new mark. SensoryFlavors also constructed the website www.sensoryflavors.com, although it states the website was “under construction” at all times and was immediately deactivated when Sensient filed the instant suit.
Shortly after Sensient filed the instant suit on March 10, 2008, the district court entered a temporary restraining order against the use of the SensoryFlavors name. SensoryFlavors subsequently changed its name to SensoryEffects Flavor Company, d/b/a SensoryEffects Flavor Systems (“SensoryEffects”), building on the prior SensoryEffects name already registered with the PTO. The company has continued to sell products and operate under this name since the change.
Sensient amended its complaint to include the new SensoryEffects name. According to Sensient, the two companies are direct competitors because they both sell flavor delivery systems to food and food ingredient companies, although their product offerings differ slightly. The initial contact with customers arises primarily through telephone calls, which leads to appointments and meetings where the company is able to present its products and services. In this sense, the ultimate sale of products is the result of an ongoing collaborative process. Sensient’s complaint contained six counts, including federal trademark infringement, unfair competition, false advertising, common law trademark infringement and unfair competition, and trademark infringement and dilution under Missouri law.
The district court granted summary judgment on all counts in favor of SensoryEffects and dismissed the case. The [760]*760court held a permanent injunction on the SensoryFlavors mark was not warranted because the mark had not been “used in commerce.” The court also held the new SensoryEffects name was not likely to cause confusion to customers and Sensient was not entitled to protection under Missouri’s trademark dilution statute. Sensient timely appeals the district court’s order.
The district court’s grant of summary judgment is reviewed de novo, and we apply the same standards as the district court. Frosty Treats Inc. v. Sony Computer Ent. Am. Inc., 426 F.3d 1001, 1003 (8th Cir.2005). Summary judgment is appropriate “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Fed.R.Civ.P. 56(c). A fact is material when it might affect the outcome of the suit under governing law. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986).
A. Whether the SensoryFlavors Name Was Used in Commerce
First, the parties dispute whether section 45 of the Lanham Act applies to infringement cases. The Lanham Act imposes civil liability on “any person who ... without the consent of the registrant ... use[s] in commerce any reproduction ... or colorable imitation of a registered mark.” 15 U.S.C. § 1114(l)(a) (emphasis added). Section 43(a) of the Act also imposes liability for “[a]ny person who, on or in connection with any goods or-services, or any container for goods, uses in commerce any word, term, name, symbol, or device, or any combination thereof ... which ... is likely to cause confusion ... as to the origin, sponsorship, or approval of goods, services, or commercial activities.” 15 U.S.C. § 1125(a)(1)(A) (emphasis added). Under section 45 of the Lanham Act, “use in commerce” is defined as follows:
The term “use in commerce” means the bona fide use of a mark in the ordinary course of trade, and not made merely to reserve a right in a mark. For purposes of this chapter, a mark shall be deemed to be in use in commerce—
(1) on goods when-—
(A) it is placed in any manner on the goods or their containers or the displays associated therewith or on the tags or labels affixed thereto, or if the nature of the goods makes such placement impracticable, then on documents associated with the goods or their sale, and
(B) the goods are sold or transported in commerce, and
(2) on services when it is used or displayed in the sale or advertising of services and the services are rendered in commerce, or the services are rendered in more than one State or in the United States and a foreign country and the person rendering the services is engaged in commerce in connection with the services.
15 U.S.C. § 1127.
In its brief, Sensient argues the press release, announcement, and two presentations provided by SensoryFlavors, in addition to its website, were sufficient to establish a question of fact regarding “use in commerce” of the mark under section 45. At oral argument, however, Sensient contradicted its argument by asserting for the first time that section 45 does not apply in infringement cases, and rather is limited in its application to the registration of trademarks. Sensient bases its contention [761]*761largely on dicta provided by the Second Circuit Court of Appeals in Rescuecom Corp. v. Google, Inc., 562 F.3d 123, 128-29 (2d Cir.2009), which involved an infringement dispute over search terms used by a popular Internet search engine. Rescue-com held Google’s display, offer, and sale of the plaintiffs mark to advertising customers was sufficiently alleged as “use in commerce” to avoid dismissal under Rule 12(b)(6) of the Federal Rules of Civil Procedure. 562 F.3d at 130-31.
After reaching its conclusion, the Rescuecom court attached a lengthy appendix analyzing whether section 45 applies in the infringement context. The court first noted the statute begins with a “guarded and tentative” limitation that the definitions provided under the statute apply “unless the contrary is plainly apparent from the context.” Id. at 132 (quoting 15 U.S.C. § 1127). The court then analyzed the 1988 amendment to the statute providing that “use in commerce” means the “bona fide use of a mark in the ordinary course of trade.” Id. at 132-33. According to the court, the amendment made clear that section 45’s definition of “use in commerce” applies only to the registration of marks, not to infringement cases, because it is “inconceivable that the statute could have intended to exempt infringers from liability because they acted in bad faith.” Id. The court believed this reading of the statute was confirmed by a Congressional report accompanying the 1988 amendment, which “explained that the revised use in commerce definition is intended to apply to all aspects of the trademark registration process, and that clearly, however, use of any type will continue to be considered in an infringement action.” Id. at 138 (citing S. Rep. 100-515 100th Cong, at 45, 1988 U.S.C.C.A.N. 5577, 5607-08 (1988)) (internal quotation marks omitted).
Pursuant to the amended statutory language, Rescuecom envisioned two possible interpretations of section 45 in infringement cases. The first interpretation bars application of the entire definition of “use in commerce” in the infringement context as a result of the new language in the first sentence relating to “bona fide use,” as discussed above. Id. at 140. The second, and preferable interpretation would continue to apply the remainder of the “use in commerce” definition relating to goods and services in infringement cases, and simply disregard the “bona fide use” language in such cases, which would be reserved for application only in the registration context.2 Id. Ultimately, the court noted its discussion was dicta that did not affect the result in the case, and it urged Congress to further clarify the statute. Id. at 140-41.
In this case, we express no view as to whether section 45’s “use in commerce” definition continues to properly apply in infringement cases. Compare 4 McCarthy on Trademarks and Unfair Competition § 23:11.50 (4th ed.) (“The Lanham Act § 45 narrowing definition of what constitutes ‘use in commerce’ is just a relaxed remnant of trademark law’s once-hyper-technical ‘affixation’ requirement. This statutory anachronism certainly was never intended to limit the scope of ‘uses’ that would constitute infringement”) with Mar[762]*762greth Barrett, Trademarks and Digital Technologies: “Use” on the Net, 13 No. 11 J. Internet L. 1, 9 (2010) (“[T]he Lanham Act’s legislative history makes it clear that Congress intended this statutory definition [of section 45] to apply in the infringement context and to carry forward the 1905/1920 Acts’ general ‘affixation or other close association’ requirement.’ ”).
Although Sensient cites the Rescuecom case in its opening brief, it confines its argument to whether SensoryFlavors’ limited uses of the mark meet the definition of “use in commerce” under section 45. Prior to oral argument, Sensient failed to develop any argument that section 45 did not apply to an infringement case such as the instant matter. See Cubillos v. Holder, 565 F.3d 1054, 1058 n. 7 (8th Cir.2009) (citation omitted) (deeming an argument waived where the petitioner referenced an argument in his opening brief, but failed to develop the argument). To the contrary, Sensient explicitly concedes in its reply brief that the statute applies to infringement cases. See Appellant’s Reply Brief at 1 (“The parties agree that the Lanham Act requires that a trademark be used in commerce before a finding of infringement can be made.”). Under these circumstances, we assume without holding that section 45 applies to infringement cases and we will proceed to determine whether SensoryFlavors’ use of its mark meets the definition of “use in commerce.” See Flowers v. Norris, 585 F.3d 413, 416 n. 2 (8th Cir.2009) (limiting review under a statute based on petitioner’s concessions in his reply brief).
Applying the language of the statute, SensoryFlavors’ goods must have been “sold or transported in commerce,” among other requirements. 15 U.S.C. § 1127. As noted above, Sensient attempts to satisfy this requirement by pointing to SensoryFlavors’ efforts to advertise and market its goods through two customer presentations, a press release, an announcement, and a website.
Sensient’s argument conflates the distinction between goods and services provided under section 45. Rescuecom and the other cases Sensient relies upon involved an alleged infringer’s services, not goods, and therefore the courts applied the separate definition provided above for determining whether the services were “used in commerce.” Rescuecom, 562 F.3d at 129 (“According to the Complaint, Google uses and sells Rescuecom’s mark ‘in the sale of Google’s advertising services rendered in commerce.’ ”) (emphasis added). Even in cases applying the services definition, many courts have held mere advertising is not enough to constitute “use in commerce” because “a mark is used in commerce only if it accompanies services rendered in commerce.” Int’l Bancorp, LLC v. Societe des Bains de Mer et du Cercle des Estrangers a Monaco, 329 F.3d 359, 364 (4th Cir.2003).
Sensient fails to show evidence of any sale or transport of any goods bearing the SensoryFlavors mark. While Sensient suggests Nicolais did not know for certain that no sales resulted from the two presentations, this assertion is weak at best because the two companies which received the presentations did not become customers of SensoryEffects subsequent to the name change. Binkley v. Entergy Operations, Inc., 602 F.3d 928, 931 (8th Cir.2010) (“In order to survive a motion for summary judgment, the non-moving party must be able to show sufficient probative evidence that would permit a finding in his favor on more than mere speculation, conjecture, or fantasy”) (citation omitted). Because there is no evidence demonstrating any sale or transport of goods under the SensoryFlavors name, Sensient fails to establish a triable issue of fact as to [763]*763whether the goods were “used in commerce,” and we affirm the district court’s grant of summary judgment on the SensoryFlavors mark.
B. Whether the SensoryEffects Name is Likely to Cause Confusion
Sensient next challenges the district court’s grant of summary judgment on the SensoryEffects Flavor Systems mark. The district court held the SensoryEffects mark was not likely to cause confusion to customers.3
The Eighth Circuit applies a six-factor test to determine whether there is a likelihood of confusion, no part of which is dispositive standing alone:
(1) the strength of the owner’s mark; (2) the similarity between the owner’s mark and the alleged infringer’s mark; (3) the degree to which the products compete with each other; (4) the alleged infringer’s intent to ‘pass off its goods as those of the trademark owner; (5) incidents of actual confusion; and, (6) the type of product, its cost, and conditions of purchase.
Frosty Treats, 426 F.3d at 1008. We do not apply any mathematical formula in analyzing these factors; “rather, we use them at the summary judgment stage as a guide to determine whether a reasonable jury could find a likelihood of confusion.” Id. We address each of these factors separately.
1. The Strength of the Owner’s Mark
In analyzing the first factor, we have recognized a “strong and distinctive trademark is entitled to greater protection than a weak or commonplace one.” Id. (citing SquirtCo. v. Seven-TJp Co., 628 F.2d 1086, 1091 (8th Cir.1980)). Marks may be characterized in four categories: generic, descriptive, suggestive, or arbitrary or fanciful. Id. at 1004. On this spectrum, an arbitrary or fanciful mark is entitled to the highest level of protection, while a generic mark is afforded no trademark protection. Duluth News-Tribune, a Div. of Nw. Publ’n, Inc. v. Mesabi Pub. Co., 84 F.3d 1093,1096 (8th Cir.1996).
In this case, the district court determined Sensient was a fanciful word coined to function as a trademark for the company. As a result, the court acknowledged Sensient’s mark was entitled to the broadest protection. However, the court also concluded Sensient could not claim an exclusive right to the “Flavors” portion of the Sensient Flavors name because “Flavors” is a generic term. Accordingly, the court determined only the Sensient name was entitled to protection. On appeal, Sensient agrees “Flavors” alone is not protectable, but it argues the Sensient Flavors mark must be construed as a whole. SensoryEffects asserts courts have routinely refused to protect generic portions of a trademark.
In making its determination, the district court noted SensoryEffects did not object to its finding that the Sensient name was fanciful. Generally, we do not consider arguments raised for the first time on appeal and a party may not assert arguments not presented to the district court. Cole v. Intern. Union, United Auto., Aerospace & Agr. Implement Workers of Am., 533 F.3d 932, 936 (8th Cir.2008). In light of SensoryEffects’ concession before the district court on this point, we need not [764]*764consider its arguments on appeal challenging the strength of Sensient Flavors’ name.
Similarly, Sensient’s argument questioning whether the district court properly analyzed its mark is largely irrelevant because the court ultimately found in favor of Sensient on the first factor. More importantly, the district court proceeded to compare the composite Sensient Flavors mark to the SensoryEffects mark later in its analysis, as demonstrated below. See, e.g., Sensient Tech. Corp. v. SensoryEffects Flavor Co., 636 F.Supp.2d 891, 900 (E.D.Mo.2009) (“SensoryEffects Flavor Systems sounds different than Sensient Flavors.”). Thus, the district court did not err in concluding the first factor favors Sensient.
2. The Similarity of the Owner’s Mark and the Alleged Infringer’s Mark
Under the second step, we must consider the similarity between the Sensient Flavors and SensoryEffects Flavor Systems marks. Frosty Treats, 426 F.3d at 1008. “Rather than consider the similarities between the component parts of the marks, we must evaluate the impression that each mark in its entirety is likely to have on a purchaser exercising the attention usually given by purchasers of such products.” Duluth News-Tribune, 84 F.3d at 1097. “The use of identical, even dominant, words in common does not automatically mean that two marks are similar.” Gen. Mills, Inc. v. Kellogg Co., 824 F.2d 622, 627 (8th Cir.1987). “We may consider the marks’ visual, aural, and definitional attributes and compare the trade dress of the products in determining whether the total effect conveyed by the two marks is confusingly similar.” Luigino’s, Inc. v. Stouffer Corp., 170 F.3d 827, 830 (8th Cir.1999) (citing Gen. Mills, 824 F.2d at 627).
The district court analyzed the evidence submitted by the parties related to the sophistication of the customer base and the collaborative process by which the products in the industry are sold. As a result of the sophisticated customers and the long, interactive purchasing process, the court determined it was highly unlikely buyers would confuse the marks, and thus the likelihood of confusion was diminished. The court also noted there was a distinct auditory difference between the marks.
The court rejected Sensient’s “initial interest confusion” argument, in which it contended SensoryEffects was able to use Sensient’s name to gain access to customers and begin the collaborative process leading to sales, even if the customer’s initial confusion over the two companies’ names dissipates during the process. The court noted this theory has never been adopted by the Eighth Circuit, and even if it was, Sensient would still lose because it failed to show any evidence of customers experiencing such a phenomenon. Not only did SensoryEffects Flavor Systems have a distinct auditory difference from Sensient Flavors, the court held, but Sensient failed to introduce evidence showing SensoryEffects attempted to lure away Sensient’s customer base by passing off its products as Sensient’s.
On appeal, Sensient contends the district court correctly recited the “sight, sound, and meaning” test to determine the similarity between the marks, see id., but it erroneously considered the purchasing conditions and evidence of actual confusion in assessing the similarity of the marks. Sensient asserts the court must independently determine whether the marks appear and sound similar and evoke a similar meaning, and then separately consider whether the purchasing conditions make those similarities more or less critical. Sensient also urges this court to formally [765]*765adopt the “initial interest confusion” doctrine.
We first consider the sight, sound, and meaning argument. We have continually held the use of identical dominant words does not automatically equate to similarity between marks. See Frosty Treats, Inc., 426 F.3d at 1008-09 (distinguishing the words “frosty treats” in the defendant’s product from the plaintiffs “Frosty Treats” mark where the mark and trade dress were visually distinct); Luigino’s, 170 F.3d at 830-31 (concluding “Lean Cuisine” and “Lean ‘N Tasty” are not confusingly similar); Duluth News-Tribune, 84 F.3d at 1097 (determining “Duluth News-Tribune” and “Saturday Daily News & Tribune” were distinct, despite the aural similarity between the two marks); Gen. Mills, 824 F.2d at 627 (holding the district court did not err in finding no confusing similarity between “Oatmeal Raisin Crisp” and “Apple Raisin Crisp” because the marks were different enough to avoid customer confusion). In this case, while each mark uses the word “flavors” and begins with the “sens” prefix, these features are components of longer product names with different auditory and visual depictions. See Everest Capital Ltd., 393 F.3d at 761 (“Though each mark uses the dominant word ‘Everest,’ that word is part of longer product names that employ different fonts and graphics.”).
First, there are significant visual differences between the marks. Sensient’s mark consists of blue capital lettering with a yellow wave slightly above the lettering. The SensoryEffects mark, on the other hand, utilizes bold black lettering in different typeface on two lines, with a multicolor swirl symbol to the left of the first line. Based on these visual distinctions, the marks are sufficiently differentiated to prevent customer confusion. See Luigino’s, 170 F.3d at 831 (“The use of different colors and typefaces, as well as the prominent display of the house marks convey perceptible distinctions between the products.”).
In its reply brief, Sensient contends the visual appearance of the marks is irrelevant because the point of contact between the companies and the customers generally occurs via telephone, and thus the auditory similarities should be given priority. Sensient’s suggestion to place particular emphasis on the verbal effect of the marks is not without merit. See ■ 4 McCarthy § 23:22 (4th ed.) (“Similarity of sound may be particularly important when the goods are of the type frequently purchased by verbal order.”). However, we agree with the district court that the composite marks maintain a distinct auditory difference. See Duluth News-Tribune, 84 F.3d at 1097 (“Although the [Duluth News-Tribune and Saturday Daily News & Tribune] marks are aurally similar, when pronounced in their entirety the word ‘Saturday’ and the ampersand in defendants’ paper make the two distinguishable.”).
While Sensient correctly notes the purchasing conditions, confusion among customers, and similarity between the marks are three separate factors considered by the court in its analysis, our precedent is clear that we evaluate the impression the entire mark is likely to have “on a purchaser exercising the attention usually given by purchasers of such products.” Id. See also Luigino’s, 170 F.3d at 830-31 (analyzing whether an ordinary consumer would be likely to be confused between the two marks). The parties agree the ordinary customer of their products is sophisticated and any particular sale is the result of a long, collaborative process. Taking into consideration the sophistication of the customers and the nature of the purchasing process, the district court correctly [766]*766determined the ordinary consumer would not find the marks confusingly similar under the “sight, sound, and meaning” test.
Sensient further argues the district court erred in its application of the “initial interest confusion” doctrine. According to Sensient, most courts now recognize the doctrine, which arises when confusion creates an initial customer interest, even though no actual sale may be finally completed due to the confusion. 4 McCarthy § 23:6 (4th ed.). Sensient contends the doctrine “may be applied to a purchasing process that is drawn out over a period of time,” such as the collaborative buying process at issue here. Id. However, those courts acknowledging the doctrine recognize that “[e]ven if the marks are almost identical, initial interest confusion is not assumed and must be proven by the evidence.” Id.
We decline Sensient’s invitation to adopt the “initial interest confusion” doctrine in this ease because, even if the doctrine applied generally in this circuit, it would not apply in this case. Under the doctrine, courts look to factors such as product relatedness and the level of care exercised by customers to determine whether initial interest confusion exists. Checkpoint Sys., Inc. v. Check Point Software Techs., Inc., 269 F.3d 270, 296 (3d Cir.2001). Here, although the products are similar, the parties agree the customers are sophisticated and exercise a relatively high degree of care in making their purchasing decisions. This sophistication makes it less likely customers will experience initial confusion, ultimately resulting in a benefit to the alleged infringer. Id. at 296-97. As a result, the district court correctly rejected the application of the doctrine under these facts. In sum, the district court did not err in concluding the second factor weighs in favor of SensoryEffects.
3. The Degree of Competition Between the Products
The third factor analyzes the degree of competition between products. Frosty Treats, 426 F.3d at 1008. If the two companies’ products are closely related, confusion among customers is more likely. Davis v. Walt Disney Co., 430 F.3d 901, 904 (8th Cir.2005). The district court determined the companies’ product markets differ slightly, but it ultimately held this factor weighed in favor of Sensient because the parties are direct competitors selling flavor delivery systems to food and food ingredient companies. Neither party disputes this holding on appeal, and accordingly we conclude the district court was correct in its determination under the third factor, which favors Sensient.
4. The Alleged Infringer’s Intent to Pass Off its Goods as the Trademark Owner’s
The fourth factor analyzes whether the alleged infringer intended to pass off its goods as the trademark owner’s goods. Frosty Treats, 426 F.3d at 1008. While proof of bad intent is not required for success in an infringement or unfair competition claim, “the absence of such intent is a factor to be considered.” Id. “Knowledge of another’s product and an intent to compete with that product is not ... equivalent to an intent by a new entrant to a market to mislead and to cause consumer confusion.” Luigino’s, 170 F.3d at 831.
In considering this factor, the district court first acknowledged the temporary restraining order it previously entered against SensoryFlavors, in which it noted Nicolais’s selection of the SensoryFlavors name after he was previously employed by Sensient created a strong infer[767]*767ence of his intent to confuse the public. However, the court concluded the evidence produced after additional discovery did not support this inference because Nicolais worked for a separate division while he was employed by Sensient, and even if he maintained knowledge of the Sensient Flavors name, his knowledge did not equate with an intent to mislead. Rather, the court determined SensoryEffects selected its name in order to capitalize its already-established mark and the goodwill established under the Givaudan Flavors name.
Sensient asserts the court ignored evidence demonstrating SensoryEffects was aware Sensient was a direct competitor prior to purchasing Givaudan Flavors and it intentionally selected similar marks. Instead, Sensient argues the court relied on the self-serving affidavit of Nicolais, who claimed he was unaware of the Sensient Flavors mark. Sensient also argues SensoryEffects was obligated to move further away from the Sensient Flavors name after the temporary restraining order was entered, such that inserting “Effects” was insufficient to meet its obligation.
In determining whether SensoryEffects intended to pass off its goods as those of Sensient’s, we believe the analysis in Luigino’s is instructive. In Luigino’s, the owners of the “Lean Cuisine” mark alleged that Luigino’s intentionally adopted a similar mark, “Lean ‘N Tasty,” to capitalize on the goodwill established under the “Lean Cuisine” mark. Id. The evidence before the court demonstrated that Luigino’s rejected a consultant’s advice to avoid the “Lean ‘N Tasty” mark and it believed the low-fat “Lean ‘N Tasty” entrees might be comparable to “Lean Cuisine” entrees. Id. Despite this evidence, this court determined there was no evidence Luigino’s intended to capitalize on the strong “Lean Cuisine” mark. Id. The court explained that Luigino’s chose the name “Lean ‘N Tasty” because it wanted to avoid the word “light,” it believed the word “low-fat” was overused, and because it did not agree with the consultant’s recommendation to avoid the word “lean.” Id. According to the court, the reference to “Lean Cuisine” only evinced an intent to compete with the product, not an intent to infringe on the mark. Id. As a result, the court held there was no genuine issue of material fact regarding predatory intent. Id.
Similarly, in General Mills, Inc., this court declined to find predatory intent on the part of the owner of the “Oatmeal Raisin Crisp” mark, despite the owner’s intent to compete with the “Apple Raisin Crisp” mark. 824 F.2d at 627. “Oatmeal Raisin Crisp” went so far as to send promotional fliers to distributors encouraging them to replace “Apple Raisin Crisp” with its product. Id. However, the court again concluded that knowledge of another’s product and an intent to compete with that product does not equate to predatory intent. Id.
We believe the intent alleged by Sensient in this case is similar to the allegations in Luigino’s and General Mills, Inc. While the parties strongly dispute the extent of Nicolais’s knowledge of the Sensient Flavors name, our precedent demonstrates any knowledge maintained by Nicolais is not dispositive of the inquiry because knowledge of another’s product and an intent to compete does not correspond with an intent to mislead. Id. Sensient alleges the inference to be drawn from the evidence is that Nicolais had an intent to confuse customers by using a name similar to Sensient Flavors; however, there is no support in the record for this assertion other than speculation.
Rather, the facts of this case are similar to Duluth News-Tribune, where the court recognized the allegedly infringing name “Saturday Daily News & Tribune” was a [768]*768logical merger of the names “Daily News” and “Daily Tribune.” 84 F.3d at 1097. Here, the prior owners of SensoryEffects filed an application for registration of the SensoryEffects name and graphic in July 2004, which was formally registered by the PTO on July 3, 2007. After PCI acquired Givaudan Flavors, it was not permitted to use the Givaudan Flavors name for more than sixty days after the purchase. As a result, the company decided to combine the SensoryEffects and Givaudan Flavors names to form SensoryFlavors. After this lawsuit was filed, the company changed its name to SensoryEffects Flavor Systems, incorporating the full SensoryEffects name that was already registered with the PTO. Under these circumstances, the district court was not incorrect in concluding the SensoryEffects Flavor Systems name was a logical combination of the previously-established SensoryEffects and Givaudan Flavors names. After a careful review of the record, we conclude no reasonable jury could find in favor of Sensient on the fourth factor.
5. Incidents of Actual Confusion
Under the fifth factor, we examine the incidents of actual confusion. Frosty Treats, 426 F.3d at 1008. Although such incidents are proof of the likelihood of confusion, the plaintiff is not required to bring forth incidents of actual confusion to succeed in an infringement case. Squirt-Co., 628 F.2d at 1091. In analyzing this factor, weight is given to “the number and extent of instances of actual confusion.” Duluth News-Tribune, 84 F.3d at 1098.
The district court held Sensient failed to produce any evidence of actual confusion, which it noted was telling since the SensoryEffects name had been in use at the time for approximately one year. As a result, the court concluded the fifth factor weighed in favor of SensoryEffects.
Sensient contends it presented evidence detailing some customers’ misguided beliefs in phone calls and correspondence where the customers thought SensoryFlavors was, in one way or another, Sensient Flavors. SensoryEffects responds Kenneth Iwanusa, National Sales Manager for Sensient Flavors, testified he knew of no lost sales, no injury to Sensient’s reputation, and no incidents in which SensoryEffects benefitted from any confusion between the two companies.
As an initial matter, it is questionable whether the statements contained in Sensient’s interrogatory responses purportedly establishing the customers’ confusion are admissible. See id. (“In evaluating the evidence at the summary judgment stage, we consider only those responses that are supported by admissible evidence.”). We need not answer this question, however, because assuming the statements are admissible, it is clear “even several isolated incidents of actual confusion that occur initially upon the creation of a potentially confusing mark are insufficient to establish a genuine issue of material fact as to the likelihood of confusion.” Id. Instead, we “look to whether an appreciable number of ordinary purchasers are likely to be so misled.” Id. at 1099. This is not the case here, because the incidents described by Sensient show only negligible confusion after SensoryFlavors was completing its transition with Givaudan Flavors, which is insufficient to meet the burden under the fifth factor.
More importantly, the district court correctly noted the alleged incidents of confusion all related to the SensoryFlavors name, not the SensoryEffects name at issue here. Sensient concedes this fact on appeal, but notes there still may be a likelihood of confusion. Sensient’s suggestion is without any support in the record, and as a result, no reasonable factfinder [769]*769could determine the fifth factor favors Sensient. Therefore, the district court did not err in concluding the fifth factor favors SensoryEffects.
6. The Type of Product, Its Cost, and Conditions of Purchase
Finally, the sixth factor examines the conditions of purchase and the degree of care expected of customers. Frosty Treats, 426 F.3d at 1008. “In considering this factor, we must stand in the shoes of the ordinary purchaser, buying under the normally prevalent conditions of the market and giving the attention such purchasers usually give in buying that class of goods.” Luigino’s, 170 F.3d at 831. This factor is “more important in confusion-of-source cases where the degree of care that the purchaser exercises in purchasing a product can eliminate the confusion that might otherwise exist.” Frosty Treats, Inc., 426 F.3d at 1010.
In this case, the district court concluded it was well-established the parties sell their products to sophisticated customers after a collaborative process. As a result of this process, the court held the likelihood of confusion was diminished, and this factor favored SensoryEffects. The parties do not dispute the conditions of purchase on appeal, as each concedes they are competitors with sophisticated customers. As noted in the analysis above, this factor is important in this case because it tends to mitigate any potential confusion. Id. As a result of the parties’ agreement, this factor could not form the basis for a verdict in favor of Sensient, and the district court did not err in concluding this factor weighs in favor of SensoryEffects.
Appropriateness of Summary Judgment
Our evaluation of the foregoing factors leads us to conclude no reasonable jury could find a likelihood of confusion between Sensient’s mark and the SensoryEffects Flavor Company mark. “As courts have repeatedly noted, the ‘core element’ of trademark infringement law is whether an alleged trademark infringer’s use of a mark creates a likelihood that the consuming public will be confused as to who makes what product.” Davis, 430 F.3d at 905 (citation and internal quotation marks omitted). Under the circumstances, SensoryEffects’s use of its mark does not create a likelihood that the sophisticated customer base will be confused as to who makes what product. As a result, we affirm the district court’s grant of summary judgment.
C. Missouri’s Anti-Dilution Statute
The district court also granted summary judgment in favor of SensoryEffects on Count Six of Sensient’s complaint alleging trademark dilution under Missouri law. The statute provides for injunctive relief where there exists a “[l]ikelihood of injury to business reputation or of dilution of the distinctive quality of a mark ... notwithstanding the absence of competition between the parties or the absence of confusion as to the source of goods or services.” Mo.Rev.Stat. § 417.061(1). “The gravamen of a dilution complaint is that the defendant’s continuing use of a mark similar to the plaintiffs mark will inexorably have an adverse effect upon the value of the plaintiffs mark, and that the plaintiffs mark will eventually be deprived of all distinctiveness.” Frosty Treats, Inc., 426 F.3d at 1011 (citation omitted). To prevail under the statute, Sensient “must show its mark or trademark was valid at common law, that its mark is distinctive, and that defendants’ use of its name created a likelihood of dilution of the distinctive quality of plaintiffs mark.” Cmty. of Christ Copyright Corp. v. Devon Park [770]*770Restoration, 683 F.Supp.2d 1006, 1017 (W.D.Mo.2010).
The district court began its analysis by noting, as discussed above, Sensient is a fanciful mark. The court proceeded to consider evidence of third party usage of similar marks on similar goods. According to the court, SensoryEffects introduced evidence showing another competitor in the market does business under the name “Sensus Flavors,” while another corporation uses the name “Symrise.” The court concluded, while the Sensient mark is fanciful, these third party uses demonstrate the mark is relatively weak. The court determined Sensient failed to introduce evidence showing its mark is distinctive, and as a result the mark was not entitled to protection under the dilution statute.
Sensient asserts it was not required to introduce evidence showing its mark was distinctive because its mark was already established as fanciful. Sensient points to its open and continuous use of the mark since 2000 on its business cards, advertising and marketing materials, and website. Sensient also contends the court erred because nothing in the statute or case law requires courts to consider third party usage as part of the dilution determination, especially where the mark at issue is fanciful. Even if this inquiry were required, Sensient argues, the court’s finding its mark was “relatively weak” was not supported by the evidence in the record.
As an initial matter, we acknowledge this case is distinguishable from Steak n Shake Co. v. Burger King Corp., 323 F.Supp.2d 983 (E.D.Mo.2004), which the district court cited in support for its holding. In Steak n Shake Co., the “steakburger” mark was a generic term not entitled to protection, in contrast to the “Sensient” mark, which the district court already determined was a strong mark, as we also concluded above. 323 F.Supp.2d at 994-95.
Regardless of this distinction, Sensient is unable to prevail on its trademark dilution claim. Inherent in a dilution action under Missouri law is a showing of similarity between the marks, which results in the dilution. See Frosty Treats, Inc., 426 F.3d at 1011 (“Plaintiffs’ Missouri-law dilution claim fails because the marks and trade dress at issue are so dissimilar that it would be clearly erroneous to hold that there was a likelihood of dilution.”). See also Luigino’s, Inc., 170 F.3d at 832 (“To support an action for dilution by blurring, the marks must at least be similar enough that a significant segment of the target group of customers sees the two marks as essentially the same.”). As discussed above, the Sensient Flavors and SensoryEffects Flavor Systems marks are not sufficiently similar under the “sight, sound, and meaning” test. While the “sight, sound, and meaning” test determined similarity for purposes of assessing whether a likelihood of confusion existed, the same dissimilarity prevents a finding of dilution under Missouri law. See Luigino’s, 170 F.3d at 832-33 (holding the marks were dissimilar under the “sight, sound, and meaning” test such that dilution did not occur because the customers did not see the marks as essentially the same); Astra Pharm. Prod., Inc. v. Beckman Instruments, Inc., 718 F.2d 1201, 1210 (1st Cir.1983) (“We have already noted that, while the Beck-man analyzer and Astra products may be in the same broad health care field, there is sufficient dissimilarity to prevent confusion. For the same reasons, there is sufficient dissimilarity to prevent dilution.”). As a result, Sensient’s dilution claim under Missouri law fails because the marks are not sufficiently similar, and therefore there [771]*771is no likelihood of dilution between the marks.
For the foregoing reasons, we affirm the judgment of the district court.
