Yes, "Kleenex" is often used as a generic term for facial tissues, but it is actually a brand name owned by Kimberly-Clark. While it might be widely recognized and used in everyday language to refer to tissues in general, the proper term for this type of product is "facial tissue." Thus, while it can function as a common noun in casual conversation, it is technically a trademarked name.
Yes. Kleenex should always be capitalized. Kleenexis a brand name therefore it's a proper noun. The word tissue, however, is not capitalized.
When it was originally registered for trademark, yes. But in common usage, it has become a lower case word in most usages. Same as kleenex, xerox, etc.
