I guess parent is talking about the use of '365' which reminds of office 365. That would be trademark infringement though, not copyright.

Seems to me that open365 is different enough of office 365 that no confusion is possible anyway but I have no idea what the law says.

You think there is no confusion possible? It's a very obvious knockoff of Microsoft's product. And unlike office, which is kind of generic, the use of 365 for a productivity suite is certainly specific to Microsoft.

365 is a descriptive term used widely to mean 'always available', it's too generic for a registered trademark by itself - Microsoft shouldn't have a hope in a sensible IP court.

It's sad that you can be sued for using numbers.

It's sad that you can't figure out a name which is not an exact replica of your competitor.

And definitely deserves the lawsuit.

MS can't copyright a number.
