Suppose you write a paper and you use Wolfram *Mathematica* to do calculations. In the article, should the program be mentioned as "Wolfram *Mathematica*" or "Wolfram *Mathematica*®" (with the "registered trademark symbol" immediately following the mark and in superscript style)?

**Related question:** Can graphics created with *Mathematica* (for example plots) be freely used in one's paper, uploaded and distributed on the internet.
