A company is in the process of trademarking a word phrase that I own in dot com. The word phrase is similar to e patch and in an up and coming bio sensors medical wearable industry. The US trademark application is now approved for publication. Is there a way I can oppose the trademark since the trademark would render me powerless to use my domain name within this medical field? The trademark may stop a suitor from purchasing my URL. I might be interested in investing in a startup by allowing the use of this domain name in exchange for company shares. Possibly this opportunity may also be interrupted by this present trademark application. I have obviously purchased the domain name 2 years ago as an intent to use because I wanted to be involved in this industries growth.
