Remember, by discussing this, you are leaving a permanent record that you are aware of its existence. If you are ever sued for violating it, and by some bizarre horrible legal accident the patent is upheld, you will be liable for treble damages. If the patent owner couldn't prove you were aware of the patent, you'd only be liable for ordinary damages.

This is why some large companies have a "never discuss patents in email" policy.

It's another way in which patent law is broken; the law actively discourages practitioners from discussing patents, even bad ones.
