From the beginning of monotheism we see strong attempts to monopolize the character of the right and the only God, dating back at least to Samaritans vs. Judeans. Some actually see the appearance of monotheism as a result of such a successful monopolization attempt. And the last 2000 years that monopoly has been enforced by sword and fire.

at least not declared heretic and burnt at stake like it was 400+ years ago for unlicensed fan-fiction produced by Luther and the likes.

1) Samaritans and Judeans do not disagree on which God they worship (it's YHWH), they disagree on much more subtle points that are largely unique to the Israelite religion like the location of the temple mount, the correct version of the pentatuch, differences in how to practice some of the rituals, etc.

2) Zoroastrianism predates the Israelite religion and is usually considered monotheistic (although some scholars disagree). If you loosen your definition to allow henotheism then some eastern traditions were first by about a millennia.

3) WTF does monotheism have to do with trademark law? I'm sure you think it's a deep argument but it just came off as a total non sequitur to everyone else.

I'm not sure if it makes sense to compare the two. Only one is openly fiction.
