> A number of common words began as trademarks but passed over into unprotectable generic terms. Aspirin, for one. And escalator. And cellophane. Dry ice. Thermos. Trampoline. For some of those, there are other words we could use for the product, but it's easy to see why we prefer to call it "aspirin" rather than "acetylsalicylic acid." For others, the term is so ingrained that it's hard to think of what else we would call the product.
