At least Microsoft has not declared to ISO that it does, even though they have had plenty of time to do so if they thought it did, and Microsoft is participating in JPEG so they are aware of the technology used in JPEG XL. But of course I am not a lawyer.”

In a phone interview, Timothy Lee, a reporter for Full Stack Economics who covered Google’s attempt to secure an ANS-based patent three years ago, said that the proliferation of patent applications related to ANS illustrates the problem with the way software patents work.

“Companies try to make minor improvements on technologies and then patent those,” he explained.

It provides ~3x better compression than JPEG at similar computational cost, compatibility with JPEG, progressive decoding, missing features like HDR, alpha, lossless, animations.

“There is a large team, mostly from Google, behind it. After nearly 30 years, it should finally replace the 1992 JPEG for photos and images, starting with Chrome, Android.”

But now, he said, Microsoft’s patent could make JPEG XL adoption more difficult.

The tangled web of patents

Others don’t consider the situation to be that dire.
Jon Sneyers, senior image researcher at Cloudinary and editor of the JPEG XL spec, told The Register in an email message, “As far as I know, this patent doesn’t affect JPEG XL.

Microsoft had applied for an rANS (range asymmetric number system) patent.

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.

“I don’t know what to do with it – [Microsoft’s patent] looks like just the description of the standard algorithm,” he told The Register in an email. The algorithm is used in JPEG XL and CRAM, as well as open source projects run by Facebook (Meta), Nvidia, and others.

The Register asked Microsoft whether it intends to seek royalties for its patent but the company has not responded.

“This rANS variant is [for example] used in JPEG XL, which is practically finished (frozen bitstream) and [is] gaining support,” Duda told The Register last year.

Bradley Kuhn, policy fellow at Software Freedom Conservancy, told The Register in an email that the SFC opposes the patenting of software algorithms completely.

“We think it’s risible that any company, and in particular Microsoft, can claim on one hand to support Free and Open Source Software (FOSS) and on the other hand continue to build their giant patent portfolios that will ultimately have chilling effects on FOSS innovation,” said Kuhn.

“Microsoft has a long history of patent aggression against FOSS; it was not too long ago that they were shaking down Linux users and Android distributors over patents, and we would expect more shakedowns to come on this and other patents.”

Kuhn said attempts to extract patent rent tend to happen behind closed doors, to pressure smaller companies into an “acqui-hire” deal or secure huge licensing payments.

Microsoft has been cleared of patent infringement by the US International Trade Commission. The case dates back to 2007 when InterDigital Inc claimed Microsoft infringed its patents, and there were calls for a ban on the import of handsets.

InterDigital Inc has been battling in court for eight years, initially trying to claim royalties on phones made by Nokia, now transferred to Microsoft.
As well as blocking the call for an import ban, the ITC stated that Microsoft did not infringe patents relating to the way mobiles make calls. In short Microsoft is in the clear and InterDigital’s rights have not been violated.

InterDigital CEO William J.
Merritt responded to the ruling with a bittersweet swipe at Microsoft.

The SFC, he said, would gladly work with any company to develop a clear, permanently binding FOSS-friendly patent license.

“What we have regarding software patents is a patchwork of inadequate ‘patent promises’ and other incomplete solutions,” said Kuhn. “For example, despite Microsoft being a member and licensee in the Open Invention Network (OIN, a for-profit industry-controlled consortium), our initial analysis shows that OIN protection will not meaningfully extend to FOSS uses that could infringe this patent.

“Similarly, standards bodies have a very poor track record in protecting FOSS from patent problems.

Google-owned Motorola will now have to shell out $14 million in damages to computer giant Microsoft. The latter, in a statement issued on Wednesday, said that a jury decided in its favour in the second of two trials in a federal court in Seattle.
The lawsuit dealt with Motorola Mobility’s licensing of standard, essential patents that are used in Microsoft’s products.

The jury, while announcing its judgment, agreed with the company’s claim that Motorola had in fact broken the agreements made with standard-setting bodies for the license on certain patents at a fair and reasonable rate, according to Microsoft. The amount awarded by the jury to the computer giant is reportedly half of what was asked for.

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.

The creator of ANS, Jarosław 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.
