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.

    It it hadn't been patentable, it would have eventually made it into the public consciousness. At that point, some interested parties would have created something very similar. It always happens.

    Extensive googling has yet to turn up any ideas similar to those of my lossless bitmap compressor, nor to its file format.

      Does it perform significantly better than 7zip?

      I could be mistaken, but my understanding was that lossless compression was a dead field as it has basically reached it's theoretical maximum.

      The emphasis now is on lossy compression as the art of learning where you can lose data and not have people notice it is still vibrant.

        ... to decompress. It's also dead-simple to implement decompression in C. That suggests it might be straightforward to implement in in an FPGA, with possible lucrative applications for ASIC such as spy satellites.

        It's dog-slow to compress, however: it only is useful if you compress just once then decompress a whole bunch of times.

        It's intended application was to replace GIF's LZW dog-slow LZW decompression on 20 MHz Windows 3.1 boxen. Our first use of it was for Medior's 2Market Home Shopping multimedia CD-ROM - that shipped _just_ in time for black friday!

        With four GIFs on each page of 2Market's catalogs, the Win GIF decompression was distressingly lagging when one browsed from page to page.

        We didn't use it on Mac OS because Apple's PICT bitmap compression was implemented in hand-optimized assembly by The Devil Incarnate.
