The district court found that there was “no possibility of confusion by the purchaser at or near the point of sale.” 894 F.Supp. at 1200. The grounds for this conclusion are apparent, but are certainly useful to discuss. Companies in the corn wet milling industry purchase clamshells directly from the manufacturers, after extensive negotiations and discussions. Fluid-Quip held itself out to this limited market as a competitor of Dorr-Oliver and conspicuously marked its elam-shells with its company name. Clearly, any purchasers of clamshells would know from whom they were buying. There is therefore no realistic possibility that anyone would purchase a Fluid-Quip clamshell believing it to be a Dorr-Oliver clamshell. See Versa Prods. Co. v. Bifold Co. Mfg.
