Rule of Law:
In determining trademark infringement, the likelihood of confusion is assessed by balancing a multi-factor test, considering elements such as the strength of the mark, proximity of the goods, similarity of the marks, and marketing channels used.
Facts:
- AMF's predecessor began using the name Slick-craft Boat Company in 1954.
- The trademark 'Slickcraft' was federally registered on April 1, 1969, and has been used continuously for a line of recreational boats advertised nationally.
- In late 1968, Nescher, a boat-builder, began using the name 'Sleekcraft' for his line of boats without knowledge of AMF's mark.
- After being notified of the alleged infringement, Nescher adopted a distinctive logo and added the phrase 'Boats by Nescher' to some of his boats and advertising materials.
- Slickcraft boats are marketed for general family recreation, while Sleekcraft boats are high-performance boats marketed to racing enthusiasts.
- Both companies sell sporty, fiberglass boats in similar size and price ranges, advertise in national magazines (though different ones), and exhibit their products at boat shows, sometimes at the same event.
Procedural Posture:
- AMF filed a trademark infringement action against Nescher in federal district court.
- The district court, after a non-jury trial, found AMF's trademark 'Slickcraft' to be valid.
- However, the district court held that Nescher's use of 'Sleekcraft' did not infringe on AMF's mark and denied AMF's request for an injunction.
- AMF, as the appellant, appealed the district court's judgment to the United States Court of Appeals for the Ninth Circuit.

Issue:
Does Nescher's use of the trademark 'Sleekcraft' for recreational boats create a likelihood of confusion with AMF's existing trademark 'Slickcraft' for a similar line of boats?
Opinions:
Majority - J. Blaine Anderson
Yes, Nescher's use of 'Sleekcraft' is likely to cause confusion with AMF's 'Slickcraft' mark. The court's reasoning is based on a comprehensive analysis of the eight relevant factors for determining likelihood of confusion. Although the goods are not directly competitive, they are extremely close in use and function. The marks 'Slickcraft' and 'Sleekcraft' are highly similar in sight, sound, and meaning, despite the district court's contrary finding. While evidence of actual confusion was negligible and Nescher's intent was innocent, these factors are not dispositive. The convergent marketing channels and the strong possibility that the companies' product lines could expand to compete directly weigh heavily in favor of finding a likelihood of confusion. Even though purchasers of expensive goods are expected to be careful, this does not eliminate the risk of confusion as to the source or sponsorship of the products.
Analysis:
This case provides a classic application of the multi-factor test for likelihood of confusion in trademark law, particularly for related but non-competing goods. It demonstrates that an appellate court can re-weigh the factors and overturn a trial court's finding on the ultimate issue of confusion if it finds clear error in the assessment of foundational facts, such as the similarity of the marks. The decision reinforces that no single factor is determinative and that the analysis is a holistic balancing act. It also underscores the principle that a trademark owner's interest is in protecting their reputation from being involuntarily placed in the hands of another, regardless of the infringer's good faith or the current quality of their product.
