Sometimes, we may refer to a product by brand name, such a Tupperware, or Kleenex, or other product. Do we absolutely have to put the notification that it is a trademarked name?If so, how do we know whether to use © or ® or the superscript "TM"???Thanks
It's ok to use brand names colloquially in online writing without adding those marks.
Oh, good! Thank you Christy! One less thing I have to worry about!
