Microsoft last month received a US patent covering modifications to a data-encoding technique called rANS, one of several variants in the Asymmetric Numeral System (ANS) family that support data compression schemes used by leading technology companies and open source projects.<\/p>\n

The creator of ANS<\/a>, Jaros\u0142aw Duda, assistant professor at Institute of Computer Science at Jagiellonian University in Poland, has been trying for years to keep ANS patent-free and available for public use. Back in 2018, Duda’s lobbying helped convince Google to abandon its ANS-related patent claim in the US and Europe. And he raised<\/a> the alarm last year when he learned Microsoft had applied for an rANS (range asymmetric number system) patent.<\/p>\n

Now that Microsoft’s patent application has been granted, he fears the utility of ANS will be diminished, as software developers try to steer clear of a potential infringement claim.<\/p>\n
