If you want to read the full lawsuit, you can do that here! It goes into all the details about Goldman's claim. Fun stuff if you're a serious person who likes reading serious legal documents.
Only time will tell how this all turns out, but the lawsuit, handled by attorney Jeffrey McFarland, alleges many transgressions including breach of implied contract, breach of confidence, and unfair competition. If the court agrees with his complaint, Goldman is looking for an injunction and monetary damages.
