Hi guys and gals,

can someone with direct experience share details on registering trademarks in US and/or Europe?

Specifically:

- type of registration: USPTO, World, Europe or combination?

- how much time it took from start to finish?

- appr. cost?

- if applied DYI style or part of SAAS [using Legal Zoom] - which provider used and was the experience positive?

- if used attorney - can you recommend someone?
