I don't think the title is positive. I assumed it to mean that Jarek Duda had joined Google, but it is Jarek speaking in the thread. I follow the data compression sphere a bit. It really seems like Google is making a mistake here. From a patent perspective, since ANS is already "prior art", it seems like it doesn't deserve a patent. Presumably Google wants to avoid receiving a misinformed lawsuit about ANS that they would then have to fight to prove that an ANS patent shouldn't be valid. Still, not putting Jarek in the loop (and like he mentions, not engaging with his university more) is wrong. The best takeaway: if anybody is also afraid of Google having a very general patent for using ANS (both tANS and rANS) in image and video compression and can explain why the above claims are just a natural mix of known methods: go to: https://efs.uspto.gov/efile/portal/efs-unregistered https://efs.uspto.gov/efile/portal/efs-unregistered select "Existing application/patent" and then "Third-Party Preissuance Submission under 37 CFR 1.290" as "Application number" enter: 15/370840 "Confirmation number": 5111
