OK, Tama had a few issues with HTC but once they saw he was coding his widget from scratch they were more than cool with him. They were just looking out for their IP with Sense UI.
IPs are totally different to copyrights in as much as you have to defend them all the time or lose your legitimate claim to them, which means they would investigate anything that looks like it might break their IP coz if they let just one thing past without challenge, then they would lose their IP.
Copyright is yours as soon as you create something artistic, photographic or literary and remain with you and your estate until up to 70 years after your death...
We won't say any more about Tama's little misunderstanding with HTC as they dealt with him fairly once they had verified the originality of his code.
