Has anyone paid Broadcom for this patent claim yet? Who? Where has this claim been made before?

This is part of what's so vicious & ugly about patents. Try as you might to avoid patents, there is a multi-decade window where some giant legion of lawyers can jump out of the bushes & make huge claims against you. Business as usual can be severely disrupted at the drip of a hat to some claim no one saw coming, with no precedent.
