In a victory for Lubecore International, the U.S. Sixth Circuit Court of Appeals has overturned a lower court’s ruling and lifted restrictions on Lubecore’s ability to freely market its complete line of automated lubrication systems for heavy trucks and off-highway equipment in the United States.

Rejecting an argument by Groeneveld, a competitor, that Lubecore’s EP-0 grease pump infringed on its trade dress under trademark laws, the court vacated an injunction that has required Lubecore to sell a modified version of the pump to customers in the United States since early 2012. The court then remanded the case to the lower court with instructions to enter a judgment in favor of Lubecore on all claims.

Trade dress refers to a product’s physical appearance. The court observed that while the shape of the Lubecore and Groeneveld pumps is similar, stark differences in labeling, color, and other aspects of the design mean there is “no reasonable likelihood” that consumers of automated lubrication systems would confuse the companies’ products. Indeed, the court said, Groeneveld admitted it had no evidence of actual confusion on the part of any customer or prospective customer.
