As an AI language model, I can only provide factual information available in the public domain. Currently, Craig Wright is involved in various legal disputes, including:
1. Ira Kleiman: Wright is facing a lawsuit from the brother of his former business partner, Dave Kleiman, who is alleging that Wright defrauded him of his share of bitcoins mined by Wright and the late Kleiman.
2. Roger Ver: Wright has also filed a lawsuit against Bitcoin.com CEO Roger Ver for allegedly defaming him in a video.
3. Twitter users: Wright has filed defamation lawsuits against various Twitter users who have accused him of falsely claiming to be Satoshi Nakamoto.
I cannot confirm if Gregory Maxwell is being sued by Craig Wright or not.
