We reported last week that Half-Life 3 was officially trademarked, well that actually turned out to be fake. It was never officially checked or authenticated so it mysteriously vanished. Now a Portal 3 trademark has been officially filed, but this one has been officially checked and authenticated.

The trademark was filed on the 2nd of October, here are the details.
Trade Mark Name: Portal 3
Trade Mark Number: 012190286
Officially Checked: Yes

So unlike the Half-Life 3 trademark this one has actually been examined and checked. It is quite weird that two of the most anticipated games from Valve would get trademarked a week apart from each other. Let’s hope that this one is actually real!
