This is not a technical question but law related.

I started developing a Delphi Application which implements a UI similar to Google Chrome:

Now I want to add a menu in the white space in left top corner (but not like of Microsoft Office UI开发者_C百科)

Can I develop and deploy my Application like this? It is not UI like Office but related to tabs just as in Ribbon so do I have to get a licence from Microsoft to make such a software (it Royalty free)

And other question: is Google Chrome UI a kind of MS Office UI? (if so have they got permisson from MS)
