Back in 2015, Personal Audio's claimed patent was invalidated by a federal court.
Podcasters, you can now engage in your lengthy Maron opens without the feeling of being legally targeted by a Texas company that many would consider to be a patent troll.
On Monday, the Supreme Court of the United States declined to hear the case of Personal Audio v. Electronic Frontier Foundation. In short, the case is all said and done.
As Ars reported in August 2017, the US Court of Appeals for the Federal Circuit affirmed the April 2015 inter partes review (IPR) ruling—a process that allows anyone to challenge a patent's validity at the US Patent and Trademark Office.

If not RSA, we'd be using a variation on Diffie-Hellman which is backed by similar mathematics. In fact, a minor variation on the D-H exchange that can be used as a public key system was known at the same time as RSA's work. Meanwhile, D-H was a re-discovery of something British Sigint worked out 7 years earlier. Look past the 50,000 foot overview of any invention and you'll most likely find others who would have invented the thing (or actually DID) but stopped once the patent office picked a winner.
The actual bolt from the blue invention is exceedingly rare
