I'm learning about trademarks, and am wondering, say you essentially put two common words together and want to trademark it, or I guess actually, service mark, like cameraMystery (for example), for a photo web site, can that type of word, be a legitimate potential trademark name? Also, as I read up on trademarking, at USPTO, it states that everything on your application is made public, even during the process. So, essentially, someone could see that cameraMystery(for example) is being applied for, and they could also apply for that name, at the same time, and get it if my application falls out for whatever reason, correct?
Here is a blog with some great information from a trademark, copyright and entertainment attorney licensed in California: http://iangibson.com/about-ian-gibson-esq/. You may find answers to your questions here. Good luck!
About your questions: -Yes you can, though before filing the registration, I would suggest you perform a trademark search and see if a similar trademark is already registered. -You do not need to worry about this, as you filed first the trademark, you have priority over anyone trying to register it.
