Not that it matters, but no, Vicks tissues are Puffs. However, if you've ever used the word Band-Aid instead of bandage, Rollerblade instead of inline skate, Styrofoam instead of polystyrene, Frisbee instead of flying disc, or Saran wrap instead of cling wrap or plastic wrap (unless you really did specifically mean those brands), then you are guilty of doing exactly the same thing. I'm sure you've done it before. And if you really want to claim to have never misused those, how about Bubble Wrap, ChapStick, AstroTurf, Crock Pot, Dumpster, Hacky Sack, Hula hoop, Lava lamp, Onesies, Popsicle, Post-It, Wite-Out, Q-Tips, Realtor, Speedo, Super Glue, Taser, and Velcro? Those are all active trademarks commonly used in a generic way. In short, get over it. Words that used to be trademarked but no longer are: heroin, aspirin, laundromat, escalator, linoleum, dry ice, thermos, and zipper. Eventually most of the words mentioned before will likely end up where those are--generic words to describe a thing, no brand implied.
