My USPTO trademark registration on a compound product name (e.g. UglyPug) shows up as a printed word in all-caps (UGLYPUG). I was told that in order to ensure I am in compliance with my USPTO registration and can legitimately use circle-R, my product literature should use all-caps rather than, say, UglyPug, since UglyPug is different from UGLYPUG.
I also have some less-important, non-registered trade names that I will want to start using (e.g., FlatCat (TM)).
I have certainly seen all-caps used in product literature, instructions, etc., for newly-emerging products, so it makes me think the above point may be valid.
1. Must I indeed stick with all-caps, at least for now, for
A. My registered product name?
B. My non-registered trade names? (E.g., if I establish use of FlatCat(TM), could someone else still grab FLATCAT from me for this product type?)
2. If I do need to use all-caps, can I compromise by, say, using UGLYPUG at the beginning of a page, and then using mixed-letters (UglyPug) the rest of the page?
3. If mixed-letter use is not protected now, when would it be protected? After wider market acceptance, a given amount of time on the market, or only after a new USPTO registration application?
