When a patent is granted, or 18 months after its filing, it's published. Until that time there's no obligation to disclose and no attorney would ever advise it. If the USPTO should rule it not patentable, it could still be a very valuable trade secret.

So it is. Go find their patents and read them. Deduce what you can.

The spokesman is under no obligation, legal or otherwise, to make this easier than necessary. That is how the game is played. Nor is he a lawyer, or foolish enough to issue an off-the-cuff statement that undercuts the work of the actual team that has crafted the wording of the patents.
