One slight error. Fluke says: "It’s important to know that once we’ve filed for and received trademark protection, US Customs has the responsibility to determine what to stop at the border, or what to seize. In this case, we first learned of this issue from SparkFun’s blog." This is only kinda correct. It's theoretically true. However, these particular items were stopped due to an ITC order, that resulted from action taken by Fluke (though not deliberately against sparkfun). See http://www.usitc.gov/publications/337/pub4210.pdf http://www.usitc.gov/publications/337/pub4210.pdf This is US ITC exclusion order 337-TA-588, which is referenced in the letter customs sent to sparkfun. This was another case where they complained about the color of some multimeters. Had this action not been taken, there is a zero percent chance customs would have done anything to sparkfun. Sadly, it's not possible to tell what the items in this order looked like for sure , because although there are "full color photographs" attached as exhibits, for some reason they scanned it in black and white ;) (The last part of the statement, about them not knowing, is almost certainly true)
