A recent search on Amazon for “MTM Special Ops” results in several other military-style watches. If Amazon doesn’t sell a specific product I’m looking for, should it simply tell me “Sorry, nothing here” or should it bring up a slate of other, possibly similar, competing products? To one high-end watchmaker that’s been involved in a four-year legal battle with Amazon, these questionable search results aren’t just an annoyance but constitute trademark infringement.
