I am currently selling a product with "Cheers to 30 years" on it. However, I noticed someone else has filed this trademark earlier this year: http://tsdr.uspto.gov/#caseNumber=88382813&caseType=SERIAL_NO&searchType=statusSearch
When I look at the Prosecution History tab on the bottom, it seems like the trademark is still being processed.
Would it be possible to register the same trademark using my product as the specimen since this current one is not approved yet? Or do I have to wait until it is published for opposition, oppose it, and then do it?
