Nature's Best, Inc. filed a motion for a preliminary injunction against Ultimate Nutrition, Inc. to prevent the latter from using the trademark "Isopreme" for whey protein supplements. Nature's Best, a distributor of health supplements, has used the trademark "Isopure" since 1998, which is registered with the U.S. Patent and Trademark Office for similar products. The plaintiff claims to have invested over $10 million in promoting Isopure, generating sales exceeding $80 million. Ultimate Nutrition, which applied for the "Isopreme" trademark in December 2002 and had it registered in February 2004 without opposition, reports sales of nearly $700,000 for its product since launch.

Nature's Best alleges trademark infringement under the Lanham Act and seeks a preliminary injunction, claiming similarity between the two trademarks and their respective goods. To succeed, the plaintiff must demonstrate either a likelihood of irreparable injury without the injunction and a strong likelihood of success on the merits, or present serious questions regarding the merits with a favorable balance of hardships. The court ultimately denied the motion for a preliminary injunction.

In Wisdom Imp. Sales Co. L.L.C. v. Labatt Brewing Co. Ltd., the court determined that the plaintiff did not demonstrate a likelihood of success on the merits or raise sufficiently serious questions for litigation, making the issue of irreparable injury irrelevant. To succeed under the Lanham Act, a plaintiff must prove ownership of a valid mark and that the defendant's use is likely to cause confusion. The plaintiff's registration of the Isopure trademark establishes its entitlement to protection, but the central issue is the likelihood of confusion, analyzed using the Polaroid factors.

The first factor, the strength of the mark, assesses its distinctiveness and ability to identify the source of goods. The court classified Isopure as a suggestive mark of moderate strength, requiring consumer imagination to connect the mark to the product, which is whey protein isolate. The court noted that while Isopure's federal registration suggests some strength, this does not equate to a strong mark in an infringement context. The prefix "Iso," which is descriptive and refers to the primary ingredient, further weakens the distinctiveness of Isopure, as it creates similarity with competing marks.

Evaluating the strength of a suggestive mark involves analyzing factors that may dilute its distinctiveness, such as third-party usage, duration of use, and sales volume. Despite Isopure's high sales and its registration since December 1999, substantial third-party use of "Iso" diminishes the mark's strength. There are over 250 "Iso" marks registered in class 5, with 66 specifically for nutritional or dietary supplements. This widespread use weakens Isopure's distinctiveness in the marketplace, a principle supported by case law indicating that extensive third-party registrations dilute a mark's strength.

The second factor in assessing trademark strength is the similarity between the marks. Courts evaluate the overall impression each mark conveys. Isopure refers to "pure whey protein isolate," while Isopreme creatively combines "Iso" with "supreme," suggesting a superior product. This difference in consumer perception implies a low likelihood of confusion. Additionally, Isopure and Isopreme differ in serving sizes, pricing, and manufacturing processes, further reducing the chances of confusion. Overall, Isopure is deemed a suggestive mark of moderate strength due to its descriptive nature and significant third-party usage.

Isopure's and Isopreme's marks are distinct enough that confusion among their sophisticated consumers—primarily bodybuilders, dieters, and individuals who have undergone weight loss surgery—is unlikely. The third Polaroid factor, proximity of the products, must be evaluated alongside the eighth factor, consumer sophistication. Although both brands are sold in the same markets, the sophistication of their consumers diminishes the risk of confusion. These consumers are knowledgeable and discerning in their purchasing decisions, particularly regarding products that affect their health and appearance. Both plaintiffs and defendants agree on the target demographic's high level of awareness about nutritional choices, further reducing the likelihood of confusion between the two brands. The fourth Polaroid factor regarding the potential for either party to enter each other's market is moot since both are acknowledged competitors. Lastly, the fifth factor, concerning actual confusion, has not been established in this case.

At the preliminary injunction hearing, the Plaintiff acknowledged no actual consumer confusion existed regarding the trademarks in question. This admission negatively impacted the fifth Polaroid factor, which assesses the likelihood of confusion. The sixth Polaroid factor examines the Defendant's good faith in adopting its mark. The Plaintiff claims the Defendant lacked good faith due to constructive knowledge of the Isopure mark from the date of its application in 1998 and argues that the Defendant's adoption of the "Isopreme" name had no good faith basis. However, the Plaintiff provided no concrete evidence of bad faith, relying instead on speculation. The Defendant presented evidence demonstrating no intent to exploit the Plaintiff's goodwill, including its established product line and marketing efforts for "Isopreme," which was derived from "Iso," a key ingredient, and "supreme," reflecting product quality. 

Regarding product quality, the Plaintiff did not argue that the Defendant's product was inferior, negating concerns about tarnishing reputation. The sophistication of the buyers was also considered, paralleling discussions from a previous factor. Overall, the court determined a low likelihood of confusion based on several factors: the suggestive nature of the Isopure mark, the moderate strength of the mark, the insufficient similarity between Isopure and Isopreme, and the sophistication of the buyers. Given the lack of evidence for actual confusion, bad faith, or inferior product quality, the Plaintiff failed to show a likelihood of success on the merits or that serious questions warranted litigation. Consequently, the Plaintiff's motion for a preliminary injunction was denied.
