Some people - who you'd think should know better - got excited last week when they learned that Sega had filed a trademark in Europe for "Shenmue III". The only problem: it wasn't actually Sega who filed it.

People scratched their heads at "Wii" but ultimately everyone accepted it. Not many are really warming up to "Wii U" but I suspect as some point that'll be spoken like it was always a part of the language, too.

We've given Tim Langdell a wide berth (like, for nearly two years) rather than assault you with incremental developments in the legal proceedings involving his ridiculous, all-encompassing trademark claims to the word "Edge." But we'll check in now, as a court ruling in the U.K. affirms what many have long suspected:…

Nintendo trademarks a piece of popular jargon so they can...send an email advertisement. Lame. Thanks Bruce!

Monday Night Combat. Evokes a sense of battle-as-primetime sport, right? Sure, thanks to a certain football broadcast. Uber Entertainment filed and owns the Monday Night Combat trademark, but it had backup plans in case the lawyer-mans raised a fuss.

You might be happy that Valve seems to be releasing a commercial product based on an old Warcraft III mod, Defence of the Ancients Allstars. Valve are probably happy too. Some of the mod's original creators, though? Less happy.

EA files three new trademark registrations for Syndicate, further teasing us with visions of a downloadable online sequel to Bullfrog's classic real-time tactics game.

We're just weeks away from getting our first official look at the Nintendo 3DS, promised to make its debut at E3. New trademarks could portend Nintendo 3DS related games that come along with it.

Square Enix may be bringing its lovely looking Final Fantasy spin-off stateside, with the company trademarking The 4 Heroes Of Light, a still unofficially announced video game from the RPG publisher.

Halo creators Bungie are cooking up something new, something that, despite its new name, may not actually follow in the trail blazed by id Software's John Carmack and involve shooting rockets into space. So what is Bungie Aerospace?

Add one more name to the pile of potential monikers for Sony's soon to be detailed PlayStation Motion Controller, the PlayStation Move.

Sony has patented a new form of trial or demo for video games that, rather than presenting us with a small piece of a title, gives us the whole thing, then takes bits away as time goes on.

A new trademark from PlayStation 3 maker Sony lends more credibility to the rumor that its forthcoming motion controller—still officially the PlayStation Motion Controller—will be called Arc. Konami's new Gradius Arc trademark, however, is something else.

Silicon Knights' psychological horror game Eternal Darkness: Sanity's Requiem was one of the bright spots in the GameCube library, so Nintendo's new refiling of the Eternal Darkness trademark warrants at least a modicum of excitement. Or does it?

Nintendo of America has taken the somewhat unexpected step of reviving its Luigi's Mansion trademark, either a sign of its very protective trademarking desires or a renewed interest in giving Luigi more face time with gamers.

Sony Computer Entertainment has filed a quartet of new trademarks that may offer a peek into the PlayStation 3 and PSP maker's upcoming software plans, including a new ninja game.
