Those decisions are consistent with the holding of the Second Circuit Court of Appeals that other forms of internal use of a trademark in website operation are not ?use? in that sense. 1-800 Contacts, Inc. v. WhenU.Com, Inc., 414 F.3d 400 (2d Cir.2005) (reversing trial court's grant of a preliminary injunction against use of plaintiff's mark to trigger pop-up advertising). The reasoning emphasizes the fact that the use of the trademark is entirely internal: the customer sees only the defendant's advertisement, which makes no mention or other use of the trademarked phrase. That ?internal utilization?, the Second Circuit concludes, ?is analogous to an individual's private thoughts about a trademark.? 414 F.3d at 409.
In short, the emerging view outside of the Second Circuit is in accord with the plain language of the statute. Because sponsored linking necessarily entails the ?use? of the plaintiff's mark as part of a mechanism of advertising, it is ?use? for Lanham Act purposes.
