How can there be pshufb patents other than Intel's 2003 patent?

Intel's 2003 patent: Method and apparatus for parallel table lookup using SIMD instructions

https://patents.google.com/patent/US20040054879A1/en

In July 2006, Intel noted that PSHUFB was available on the Core 2 Duo CPUs, such as the X6800, to some companies and universities working with error correction code. I recall some published programs that were using it later on that year (around September 2006). However I've seen one or more later patents (2010 or later) that include using PSHUFB for parallel table lookup, which doesn't make sense.

Hello @samlex, 

Thanks for joining our community. 

I do not know exactly how this fits Cloudera scope, but very interesting question. 

Reading some other information and searching for that, I found other patents that do have PSHUFB used. 
For example: 
https://patents.google.com/patent/US11848686B2/en 
https://patents.google.com/patent/US11362678B2/en 

Can you tells us more how this relates to Cloudera? Maybe we can get some specific help on that field if this applies.
