It's easy to take five minutes to search the online US trademark database before settling on a name. Of course that's not exhaustive, but it would have avoided this situation.
I'm not from America, the project originated in Canada. I'm not seeing it in our DB (unless I'm searching wrong). Time for a foundation maybe? Sucks that open-source contributors have to pay for stuff like this.
Only the US trademark database?
Jade Software shows up as dead in that database. Hmmm.
This seems rather important.
Jade Software are a New Zealand-based company. They've been around for decades.
