I manage the Intellectual Property for a high tech plastic company...so I know a bit about trademarks and "branding" (actually two different things).
If the name you want..."would cause confusion in the marketplace"...and it's obviously in the same trade class...then it would be inadvisable to utilize the name.
PM me your name and the trademarked name ....and I'll give you a better opinion. If you want to try and trademark the name, I would strongly suggest you consult a Trademark Attorney (I could recommend a reasonable cost one to you).- Andy
