How does the letter from the law firm addressed to me stating co/inventor had no legal right to assigen or or sell patent ? effect patent now soley in my name. Owner of patent who put it in my name now says there is a grey cloud over my patent.

In most cases (US at least) first-to-file is the decisive factor as to whom owns the patent, and the filer decides who is listed as the inventors of the patent.

If you are an employee of the company, you most likely have signed away any rights to inventions, and made your company the default assignee for any work related inventions and patents -- i.e. your company owns the result of your work regardless of whether it is used.

You cannot yourself ask for being a co-inventor after the patent is filed, only the filing authority can do that, and usually that is not done.

What about the copyrights? – Pacerier Jun 5 '14 at 2:03
@Pacerier -- you should open that as a new question, and not as a discussion to this one. – Soren Jun 5 '14 at 15:19
