I'm kind of glad this happens to Novartis.
Our company (devartis) received an oposition from Novartis against our trademark registration solicitude in Argentina due to the similarity of the names. The funny thing is that they registered theirs in a different category and the similar part is the word "artis" (which is art in latin), and dictionary words can't be owned.
I wonder how many software companies have the word soft in their names.
