Lets say hypothetically 5 years ago someone (Person A) created a company with someone else (Person B) and they split the company 80 (Person B) / 20 (Person A) and then used that company information to create an apple developer account to create an application. The application never got released but the apple developer account still remained. The company was not dissolved but no real work was really done to further the company's interests after this point.
Now 5 years later the developer (Person A) logs into the account again and uses his own money to reinstate the account to release an independently developed game. But all the developer account information is under the previous entity. The developer releases the game and it grows in popularity and makes money. The developer collects the money for a while.
Then Person B discovers the game and that it has the old entity name under the game. Person B sues Person A and demands back payment of 60% of the profits.
Does Person B have a case that could likely win? At what point does an Application or Website become the possession of an Entity or Company? Does this have to be spelled out by a contract or is it all "implied"?
This is hypothetically in New Jersey in the United States
