1-800 Contacts Inc. v. Lens.com

1-800 Contacts Inc. (plaintiff) sued Lens.com (defendant) for trademark infringement based on initial-interest confusion. Lens.com's affiliates bought Google AdWords keywords similar to 1-800's mark, generating links to Lens.com, though the ads themselves did not display 1-800's trademark. The evidence showed only minimal consumer confusion. The district court granted summary judgment to Lens.com, and 1-800 appealed.

Whether initial-interest confusion is a valid basis for a trademark-infringement claim under the Lanham Act, and whether the plaintiff produced enough evidence of confusion to survive summary judgment.
