What is the name of your state (only U.S. law)? New York (National product)
Is there a way to see if a company has a history of opposing trademark registrations that may interfere with their trademark?
jnr47, if you still have plans to use the other apparel company's trademark, and you want to check to see if they have opposed the registration of same or similar names in the past, you can make use of the information provided on the United States Patent and Trademark Office's website.
You may wish to look at the final decisions made by the Trademark Trial and Appeal Board on oppositions to trademark registrations. Opposition files are public records and you can either go to the TTAB's offices to find and copy them, or you can hire someone to find and copy them for you.
Or, if you are just interested in viewing decisions online, TTAB decisions from 1997 to the present are published and accessible from the home page:
http://www.uspto.gov/index.jsp. You can also try
http://e.foia.uspto.gov/Foia/TTABReadingRoom.jsp for internet listings.
If you have difficulty locating what you want, you can call the TTAB's customer service line at 571-272-8500 for direction.
As mentioned in your other thread, you may find it easier to come up with an alternate name for your apparel company, one that is unique to you alone (actually, as it turns out, that
wasn't mentioned in your other thread. . . but it should have been
).
Good luck.
