The specific structure of the company does not matter. Use in commerce for trademarks or the filing date for intent to use trademarks, and originality for both types of trademarks, is of greater importance.
The above is general legal and business analysis. It is not "legal advise" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

For purposes of a trademark, it does not matter if your entity is a corporation or a limited liability company. There are other reasons to consider one form of entity over the other, but not for the protection of intellectual property. I recommend that you consult with an attorney and/or your accountant to fully consider the benefits of both types of entity and determine which would be the best for your company.
I wish you good luck.

A trademark does not depend on the structure of the company.
J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
A trade name technically cannot be trademarked -- only a mark that is directly connected with a good or service can be trademarked, although it is normal to assume that you are using your trade name in connection with the goods or services you sell. Assuming that you are using the trade name as a trademark, it is better, if possible, to use "My Company Name" as the trademark, rather than "My Company Name Inc." or "My Company Name LLC." However, you should discuss your options with a competent intellectual property attorney nearby; you may be missing some options that could save you money and/or increase revenue in the long run.
