Looks like Cisco was having meetings with Centripital about their technology to detect malware through unencrypted portions of a packet without requiring the payload to be decrypted.
Centripital used an analytics engine based off netflow, and then tagged network traffic to be processed by stateless filters.
Cisco implemented a similar function in their IOS XE platform - tagging network packets by Group Tag Labels through ISE/Stealthwatch and filtering traffic based off it.
Cisco must also pay Centripetal Networks a 10 percent royalty on the Cat9k, ISR1k, ISR9k, and Encrypted Traffic Analytics (which was only available if you bought Stealthwatch) over the next five years, with that percentage dropping to 5 percent for the subsequent three years.
That's not a cheap punishment.
Another hilarious fact from the trial is that Cisco was forced to use Zoom for VC (Shock! Horror!) after they tried to argue that Webex was more secure then Zoom. From the Forbes article:
The first virtual patent-infringement bench trial was held using Zoom after the judge rejected Cisco's arguments that it posed a security threat and using Cisco Webex software would be the safer alternative.
What an absolutely petty thing to require when you're being sued!
