No, they’re in a patent pool. There’s what looks like a relatively up-to-date list at https://en.wikipedia.org/wiki/Via-LA#H.265/HEVC_licensors

5203 active patents for HEVC, 1480 for H.264. That's just plain insane! I get that video formats are complex, but complex enough to consist of 5000+ distinct, nontrivial inventions?

Many of those are just marginally related, and might not apply to the actual standard.
