Now, you might claim that perhaps PacketVideo has a legitimate patent claim here. After all, the company has been around for well over a decade and was an early pioneer in streaming efforts. But... the details suggest not so much. The actual patent in question, 5,636,276, is for a "Device for the distribution of music information in digital form." Sound broad? Of course, as the patent attorneys in the audience will tell you, it's not the title of the patent that matters, but the claims. So go read through the claims and try not to gag. What's described is the very generic idea of streaming music. Here's the key claim:
a central memory device which is connected to a communications network and has a databank of digitized music information and, a terminal which is connected to the central memory device via the communications network, the central memory device being equipped with a retrieval module and the said modules having the capability to interact via the communications network in order to order and transmit selectively chosen music information, wherein the selectively chosen music information is organized with a defined format for transmission in a digital music information object, the format including a core and a number of additional layers, the core including at least one object identification code, object structure information, a consumer code and an encryption table and the one or more additional layers including the actual music information, wherein the central memory device has an encryption module for encryption of the music information object before transmission using the encryption table, and wherein the terminal has a decryption module for decryption of the music information object before its reproduction using the encryption table, an interpretation module for interpretation and reproduction conditioning of the music information object as well as an authorization device having identification information for identification of the terminal and of the consumer which is retrievable by the interpretation module and by the decryption module for authorization checking.Now here's the thing. When this patent was filed in 1995, this was not a unique idea. You could have asked any semi-competent engineer how would you build a digital music streaming service, and you would have received a similar general explanation. The problem was never in understanding the various pieces you need to put together. The difficulty at the time was getting enough bandwidth to do this reasonably... and getting any sort of licensing in an era before most label execs even knew what the internet was.
Oh, and let's get to the important part: PacketVideo had nothing to do with this patent. The company just bought it a few years back. There's nothing in this patent that was some amazing breakthrough or key innovation. Spotify is an amazing product, not because of this patent, but because of how it actually executed and built a working product.
Once again, we see patents being used as a tool to shakedown companies who were actually innovative in how they executed, with a ridiculously broad patent that contributed zippo to the actual state of the art.
