How can I determine if a prior trademark may constitute an obstacle?
The main test for determining the similarity between two trademarks is to see if your proposed trademark is likely to cause confusion among consumers so that they might mistake the two suppliers of products or services for each other. For example, it would be confusing to have a software company called "Micrasoft" because there is already a software company called "Microsoft."
We can conduct this analysis of the trademark(s) revealed by your search, should you prefer to obtain a professional appreciation of the risks.
