Codec2 might be patent-free, but Codec2 with a WaveNet decoder isn't because WaveNet (convolutional neural networks for generating audio sequence data) is patented: https://patents.justia.com/patent/20180075343 https://patents.justia.com/patent/20180075343
- triangleman 8y agoraises hand Question for IP experts: now that I have heard of the existence of WaveNet and a rough idea of how it works (training a neural network to decode low-bitrate speech data with as much fidelity as possible to the original), would I be prohibited from selling a similar product built with the same technique? How about if I had never heard of WaveNet and went about doing the same thing?
- particleman2 8y agoWhy do you hate me?
- matt4077 8y agoYes, independent implementations of patented works are covered by the patent. BUT: patents are far more specific than just "a neural network to decode low-bitrate speech data with as much fidelity as possible to the original)". Starting with that goal, you are unlikely to recreate WaveNet's specific structure that is patented. In fact, WaveNet describes a more general method to efficiently work with sound signals, somewhat comparable to convolutions for images. It's also not impossible to work with sound using alternative MM structures that are not patented, and might actually perform better than WaveNet.
- c3534l 8y agoWaveNet is actually a bit more complicated than that. But its still probably recreatable if you read the paper.
- merinowool 8y agoWhen it was patented? When I was working with AI about 15 years ago I was experimenting with conv nn to generate audio. I wouldn't have expected for this to be patented as this is so friggin obvious thing to do. It is like patenting 2+2=4 once you discover numbers.

- andai 8y ago[Serious question] Does your prior art invalidate the patent?
- merinowool 8y agoI am not a scientist, just I was very interested in that space and it would be a long way to create scientific paper out of my experiments. Since patent law has been created for the privileged to reap profits I wouldn't stand a chance contesting that.
- zouhair 8y agoIsn't that specifically what software patents are? Pythagoras could have become a billionaire in his time and don't get me started on Al Khwarizmi.
