In a reverse confusion trademark infringement case, the senior trademark owner claims that customers are confused by the junior infringer into thinking that the senior’s goods emanate from the junior because of its higher public profile.  Here, IronHawk was the senior user of SmartSync for its file compression and transfer software.  It claimed that Dropbox’s use of Smart Sync on its cloud storage software created reverse confusion.  This opinion holds that the trial court erred in entering summary judgment for Dropbox as there were triable issues of fact as to the nature of the “consuming public” for IronHawk’s product.  Though it had so far sold only to the US Navy, its evidence raused a triable issue as to whether it was trying to broaden its customer base to include commercial enterprises as well.  And numerous triable issues arose with regard to the 8 Sleekcraft factors used to determine the likelihood of confusion in trademark infringement cases.   AMF Inc. v. Sleekcraft Boats, 599 F.2d 341, 348-49 (9th Cir. 1979).  The dissent would affirm the summary judgment as confusion was unlikely given the size and sophistication of IronHawk’s existing and potential customers and the care with which they vetted products before purchasing them.
