They'll contact you with the extension and it will be done. I will submit when they activate it. I just need feedback from you so I know a lot more regarding the direction you want.
As I see it, the logotype shouldn't look to masculine or have a construction feel, since the patented product you are promoting has an added arhitectural (design) added value. So the logo should me more stylish and accentuate de uniqueness aspect for the client.
Cheers!
