tldr: "...corporate patent defendants can only be sued where they are incorporated or where they allegedly infringe the patent and have a regular and established place of business."

I wonder what the patent-scam scum will pivot to. Probably making sure no one in the Eastern District of Texas maintains a regular business there, then creating new cancerous jurisdictions elsewhere in the USA, perhaps Delaware. That's probably too hard a nut to crack. I think the cancer will metastasize.
