Legal Question in Intellectual Property in California

You may. We would need to understand fully all the facts and circumstances in order to reach a conclusion. For example, are there any written agreements in place? Were you considered an employee at the time these works were created?

I suggest that you discuss this over with a lawyer in private to explore your options.

If you would like to discuss further over a free phone consult, feel free to contact me anytime that is convenient.

Kind regards,

While I can't say I disagree with the previous answer, I am somewhat more doubtful that you have a case, for the following reason. It sounds as though you were composing the music only, and not writing the lyrics. Now, they're using a different composer to write the music for the same lyrics -- which lyrics were written by a third person. Based on this analysis (which may be incorrect), I'd say you have no creative connection or influence on the final product, and therefore have no claim under intellectual-property laws. You would have a claim, of course, if you were an employee or under contract and the terms of your employment or contract were breached.
