Space marines are nothing new, before Gears of War or War hammer 40k, there was Star Craft, and before that Quake and Doom. Hell some of the old Star Trek books mention "Space" marines.
Space Marines are a part of Science Fiction the way Elves, Orcs, Wizards and Swordsmen are apart of Fantasy. I don't see Wizards of the Coast calming Legend of Zelda Ripped off the Original Dungeons and Dragons.
You seem to think that Blizzard didn't rip off the story/ideas for both Warcraft and Starcraft from GW. A little history lesson, a long time ago the two companies had agreed to work together to create said games... but that didn't work out. (Who broke up with who for what reason is debatable, though Blizzard most certainly ran away with much of the Warhammer lore.)
If you ever bother to read the backstory of Warhammer and the stories of Warhammer 40k, you'll notice that Warcraft was originally a clear lore rip from Warhammer, similarly for a lot of the Starcraft story but with some things changed from Eredar to Protoss, and the such.
GW invented, for lack of a better word, the modern Space Marine persona, just as Tolkein invented the modern persona of Elves. Their ideas are taken from past creations, sure, but that doesn't change the fact that what you see in modern days is a direct copy of their work.
