An anonymous reader quotes a report from Ars Technica: AOMedia Video 1 (AV1) was invented by a group of technology companies to be an open, royalty-free alternative to other video codecs, like HEVC/H.265. But a lawsuit that Dolby Laboratories Inc. filed this week against Snap Inc. calls all that into question with claims of patent infringement. Numerous lawsuits are currently open in the US regarding the use of HEVC. Relevant patent holders, such as Nokia and InterDigital, have sued numerous hardware vendors and streaming service providers in pursuit of licensing fees for the use of patented technologies deemed essential to HEVC.

It's a touch rarer to see a lawsuit filed over the implementation of AV1. The Alliance for Open Media (AOMedia), whose members include Amazon, Apple, Google, Microsoft, Mozilla, and Netflix, says it developed AV1 "under a royalty-free patent policy (Alliance for Open Media Patent License 1.0)" and that the standard is "supported by high-quality reference implementations under a simple, permissive license (BSD 3-Clause Clear License)."

Yet, Dolby's lawsuit filed in the US District Court for the District of Delaware [PDF] alleges that AV1 leverages technologies that Dolby has patented and has not agreed to license for free and without receiving royalties. The filing reads: "[AOMedia] does not own all patents practiced by implementations of the AV1 codec. Rather, the AV1 specification was developed after many foundational video coding patents had already been filed, and AV1 incorporates technologies that are also present in HEVC. Those technologies are subject to existing third-party patent rights and associated licensing obligations." Dolby is seeking a jury trial, a declaration that Dolby isn't obligated to license the patents in questions under FRAND (fair, reasonable, and non-discriminatory) licensing obligations, and for the court to enjoin Snap from further "infringement."

Walmart has secured patents for systems that use machine learning to forecast demand and automate pricing decisions, "pushing the U.S. retail behemoth into a debate over the use of algorithms to adjust product costs," reports the Financial Times. From the report: In January Walmart obtained a U.S. patent for a "system and method for dynamically and automatically updating item prices" to carry out markdowns in its ecommerce unit, a rapidly growing division that generated more than $150 billion in sales last year. Last week it received another patent for using machine learning to predict demand and recommend prices for goods. [...] Walmart said that both patents were "unrelated to dynamic pricing," as the patent issued in January was specific to markdowns and last week's patent was designed for merchant teams to make decisions, not the technology.

The patent granted in January involves an "end-to-end price markdown system" for ecommerce platforms such as Walmart.com based on data including predicted demand and consumers' price sensitivity. Last week's approved patent outlines ways to forecast demand and set prices at levels that will move stock over periods such as a week, a month or a quarter. "Example categories may include, for example, a food item, outdoor equipment, clothing, housewares, toys, workout equipment, vegetables, spices," according to the filing. The "demand forecasting and price recommendation" tool envisaged in the patent would incorporate sources including purchases, prices, methods of payment and customer ID, such as a passport or driver's license number. "Dynamic pricing or anything that smells like it is playing with fire," said Matt Hamory, a grocery industry consultant at AlixPartners, who cited "the goodwill that you can lose by getting customers to think or suspect or worry even slightly that you are doing things with pricing that are to your benefit and their detriment."

The Supreme Court of the United States declined to review a case challenging the U.S. Copyright Office's stance that AI-generated works lack the required human authorship for copyright protection, leaving lower court rulings intact. The Verge reports: The Monday decision comes after Stephen Thaler, a computer scientist from Missouri, appealed a court's decision to uphold a ruling that found AI-generated art can't be copyrighted. In 2019, the U.S. Copyright Office rejected Thaler's request to copyright an image, called A Recent Entrance to Paradise, on behalf of an algorithm he created. The Copyright Office reviewed the decision in 2022 and determined that the image doesn't include "human authorship," disqualifying it from copyright protection.

After Thaler appealed the decision, U.S. District Court Judge Beryl A. Howell ruled in 2023 that "human authorship is a bedrock requirement of copyright." That ruling was later upheld in 2025 by a federal appeals court in Washington, DC. As reported by Reuters, Thaler asked the Supreme Court to review the ruling in October 2025, arguing it "created a chilling effect on anyone else considering using AI creatively." The U.S. federal circuit court also determined that AI systems can't patent inventions because they aren't human, which the U.S. Patent Office reaffirmed in 2024 with new guidance. The UK Supreme Court made a similar determination.

China's courts are now handling more than 550,000 intellectual-property cases a year -- making it the world's most litigious country for IP disputes -- as the nation's own companies, once notorious for copying foreign designs and technology, find themselves on the defensive against a domestic counterfeiting epidemic fueled by excess factory capacity.

The problem runs from knockoff "Lafufu" plush toys (cheap copies of Pop Mart's wildly popular Labubu dolls, which prompted a nationwide crackdown and a Shanghai police bust of a $1.7 million stash in July) to copied motorcycles and solar panels. Judges in Shanghai, the preferred venue for IP litigation, are working through cases at a rate of roughly one per day, and it still takes three months for a case to land on a court's docket.

Chinese companies are also increasingly clashing abroad: patent-related cases involving Chinese businesses in America surged 56% in 2023, according to data from GEN, a Chinese law firm. Luckin Coffee and Trina Solar have both filed suits against foreign-based copycats.

Meta was granted a patent in late December that describes how a large language model could be trained on a deceased user's historical activity -- their comments, likes, and posted content -- to keep their social media accounts active after they're gone.

Andrew Bosworth, Meta's CTO, is listed as the primary author of the patent, first filed in 2023. The AI clone could like and comment on posts, respond to DMs, and even simulate video or audio calls on the user's behalf. A Meta spokesperson told Business Insider the company has "no plans to move forward" with the technology.

An anonymous reader shares a report: Apple is being sued by Reincubate, which makes the Camo smartphone webcam app. It has filed a lawsuit against Apple in a U.S. federal court in New Jersey, accusing the company of anticompetitive conduct and patent infringement. The suit alleges that Apple copied Camo's technology, integrated similar features into iOS, and used control over its software ecosystem to disadvantage Reincubate's Camo product.

Reincubate's Camo and Camo Studio apps allow iOS or Android phones to function as webcams for Mac and PCs. The company launched Camo in 2020. In 2022, Apple introduced Continuity Camera, a feature that enables iPhones to serve as webcams for Macs but works only within Apple's device ecosystem. According to the lawsuit, Apple copied patented features from Camo and built them into iOS to "redirect user demand to Apple's own platform-tied offering."

Slashdot reader BrianFagioli writes: Acer has filed three separate patent infringement lawsuits against AT&T, Verizon, and T-Mobile, taking the unusual step of hauling the nation's largest wireless carriers into federal court. The suits, filed in the Eastern District of Texas, claim the companies are using Acer-developed cellular networking technology without paying for the privilege. Acer says it tried to negotiate licenses for years but reached a dead end, arguing it was left with no option except litigation. The case centers on six U.S. patents Acer asserts are core to modern wireless networks, rather than anything tied to PCs or laptops.

The company describes itself as reluctant to pursue courtroom battles, but it has been quietly building a large global patent portfolio after pouring hundreds of millions of dollars into R&D. Acer also notes that some of its patents count as standard-essential, hinting the carriers may be required to license them. All three companies are expected to push back, and the dispute could become another long-running telecom patent saga. Consumers will not notice any immediate changes, but if Acer wins or settles, it may find a new revenue stream far beyond its traditional hardware business.

Matthew McConaughey is taking a novel legal approach to combat unauthorized AI fakes: trademarking himself. From a report: Over the past several months, the "Interstellar" and "Magic Mike" star has had eight trademark applications approved by the U.S. Patent and Trademark Office featuring him staring, smiling and talking. His attorneys said the trademarks are meant to stop AI apps or users from simulating McConaughey's voice or likeness without permission -- an increasingly common concern of performers.

The trademarks include a seven-second clip of the Oscar-winner standing on a porch, a three-second clip of him sitting in front of a Christmas tree, and audio of him saying "Alright, alright, alright," his famous line from the 1993 movie "Dazed and Confused," according to the approved applications. "My team and I want to know that when my voice or likeness is ever used, it's because I approved and signed off on it," the actor said in an email. "We want to create a clear perimeter around ownership with consent and attribution the norm in an AI world."

"The ancient evolution of fish mouths could help solve a modern source of plastic pollution," writes ScienceAlert.

"Inspired by these natural filtration systems, scientists in Germany have invented a way to remove 99 percent of plastic particles from water. It's based on how some fish filter-feed to eat microscopic prey." The research team has already filed a patent in Germany, and in the future, they hope their creation will help curb a ubiquitous form of plastic pollution that many are unaware of. Every time a load of laundry is done, millions of microplastics are washed from the fibers of our clothes into local waterways. By some estimates, up to 90 percent of plastic in 'sewage sludge' comes from washing machines. This material is then often used in agriculture as soil or fertilizer, possibly exposing those who eat the resulting crops to these pollutants...

Unlike other plastic filtration systems on the market, this one reduces clogging by 85 percent.

In 1975, 23-year-old electrical engineer Steve Sasson joined Kodak. And in a new interview with the BBC, he remembers that he'd found the whole photographic process "really annoying.... I wanted to build a camera with no moving parts. Now that was just to annoy the mechanical engineers..." "You take your picture, you have to wait a long time, you have to fiddle with these chemicals. Well, you know, I was raised on Star Trek, and all the good ideas come from Star Trek. So I said what if we could just do it all electronically...?"

Researchers at Bell Labs in the US had, in 1969, created a type of integrated circuit called a charge-coupled device (CCD). An electric charge could be stored on a metal-oxide semiconductor (MOS), and could be passed from one MOS to another. Its creators believed one of its applications might one day be used as part of an imaging device — though they hadn't worked out how that might happen. The CCD, nevertheless, was quickly developed. By 1974, the US microchip company Fairchild Semiconductors had built the first commercial CCD, measuring just 100 x 100 pixels — the tiny electronic samples taken of an original image. The new device's ability to capture an image was only theoretical — no-one had, as yet, tried to take an image and display it. (NASA, it turned out, was also looking at this technology, but not for consumer cameras....)

The CCD circuit responded to light but could only form an image if Sasson was somehow able to attach a lens to it. He could then convert the light into digital information — a blizzard of 1s and 0s — but there was just one problem: money. "I had no money to build this thing. Nobody told me to build it, and I certainly couldn't demand any money for it," he says. "I basically stole all the parts, I was in Kodak and the apparatus division, which had a lot of parts. I stole the optical assembly from an XL movie camera downstairs in a used parts bin. I was just walking by, you see it, and you take it, you know." He was also able to source an analogue to digital converter from a $12 (about £5 in 1974) digital voltmeter, rather than spending hundreds on the part. I could manage to get all these parts without anybody really noticing," he says....

The bulky device needed a way to store the information the CCD was capturing, so Sasson used an audio cassette deck. But he also needed a way to view the image once it was saved on the magnetic tape. "We had to build a playback unit," Sasson says. "And, again, nobody asked me to do that either. So all I got to do is the reverse of what I did with the camera, and then I have to turn that digital pattern into an NTSC television signal." NTSC (National Television System Committee) was the conversion standard used by American TV sets. Sasson had to turn only 100 lines of digital code captured by the camera into the 400 lines that would form a television signal.
The solution was a Motorola microprocessor, and by December 1975, the camera and its playback unit was complete, the article points out. With his colleague Jim Schueckler, Sasson had spent more than a year putting together the "increasingly bulky" device, that "looked like an oversized toaster." The camera had a shutter that would take an image at about 1/20th of a second, and — if everything worked as it should — the cassette tape would start to move as the camera transferred the stored information from its CCD [which took 23 seconds]. "It took about 23 seconds to play it back, and then about eight seconds to reconfigure it to make it look like a television signal, and send it to the TV set that I stole from another lab...." In 1978, Kodak was granted the first patent for a digital camera. It was Sasson's first invention. The patent is thought to have earned Eastman Kodak billions in licensing and infringement payments by the time they sold the rights to it, fearing bankruptcy, in 2012...

As for Sasson, he never worked on anything other than the digital technology he had helped to create until he retired from Eastman Kodak in 2009.

A startup called Operation Bluebird is petitioning the US Patent and Trademark Office to strip X Corp of the "Twitter" and "tweet" trademarks, hoping to relaunch a new Twitter with the old brand, bird logo, and "town square" vibe. "The TWITTER and TWEET brands have been eradicated from X Corp.'s products, services, and marketing, effectively abandoning the storied brand, with no intention to resume use of the mark," the petition states. "The TWITTER bird was grounded." Ars Technica reports: If successful, two leaders of the group tell Ars, Operation Bluebird would launch a social network under the name Twitter.new, possibly as early as late next year. (Twitter.new has created a working prototype and is already inviting users to reserve handles.)

Michael Peroff, an Illinois attorney and founder of Operation Bluebird, said that in the intervening years, more Twitter-like social media networks have sprung up or gained traction -- like Threads, Mastodon, and Bluesky. But none have the scale or brand recognition that Twitter did prior to Musk's takeover. "There certainly are alternatives," Peroff said. "I don't know that any of them at this point in time are at the scale that would make a difference in the national conversation, whereas a new Twitter really could."

Similarly, Peroff's business partner, Stephen Coates, an attorney who formerly served as Twitter's general counsel, said that Operation Bluebird aims to recreate some of the magic that Twitter once had. "I remember some time ago, I've had celebrities react to my content on Twitter during the Super Bowl or events," he told Ars. "And we want that experience to come back, that whole town square, where we are all meshed in there." "Mere 'token use' won't be enough to reserve the mark," said Mark Lemley, a Stanford Law professor and expert in trademark law. "Or [X] could defend if it can show that it plans to go back to using Twitter. Consumers obviously still know the brand name. It seems weird to think someone else could grab the name when consumers still associate it with the ex-social media site of that name. But that's what the law says."

Microsoft Excel, the 40-year-old spreadsheet application that helped establish personal computers as essential workplace tools and contributed to Microsoft's current valuation of nearly $4 trillion, has weathered both the rise of cloud computing and the current AI boom largely unscathed. In its most recent quarter, commercial revenue for Microsoft 365 -- the bundle including Excel, Word, and PowerPoint -- increased 17% year over year, and consumer revenue rose 28%.

The software traces its origins to a 1983 Microsoft offsite under the code name Odyssey, where engineers set out to clone Lotus 1-2-3. That program had itself cloned VisiCalc, the first computerized spreadsheet, created by Dan Bricklin for the Apple II in the late 1970s. Bricklin never patented VisiCalc. "Financially it would have been great if we'd have been able to patent it," he told Bloomberg. "And there would be a Bricklin Building at MIT, instead of a Gates Building."

Excel now counts an estimated 500 million paying users. The Pentagon pays for 2 million Microsoft 365 licenses. Google's free Sheets product, launched in 2006, captured casual use cases like potluck sign-ups but failed to dislodge Excel from enterprise work. AI chatbots present the latest challenge, but venture capitalists say nearly every AI spreadsheet startup they meet builds on top of Excel rather than replacing it.

An anonymous reader quotes a report from 404 Media: Flock, the automatic license plate reader and AI-powered camera company, uses overseas workers from Upwork to train its machine learning algorithms, with training material telling workers how to review and categorize footage including images people and vehicles in the United States, according to material reviewed by 404 Media that was accidentally exposed by the company. The findings bring up questions about who exactly has access to footage collected by Flock surveillance cameras and where people reviewing the footage may be based. Flock has become a pervasive technology in the US, with its cameras present in thousands of communities that cops use every day to investigate things like carjackings. Local police have also performed numerous lookups for ICE in the system.

Companies that use AI or machine learning regularly turn to overseas workers to train their algorithms, often because the labor is cheaper than hiring domestically. But the nature of Flock's business -- creating a surveillance system that constantly monitors US residents' movements -- means that footage might be more sensitive than other AI training jobs. [...] Broadly, Flock uses AI or machine learning to automatically detect license plates, vehicles, and people, including what clothes they are wearing, from camera footage. A Flock patent also mentions cameras detecting "race." It included figures on "annotations completed" and "annotator tasks remaining in queue," with annotations being the notes workers add to reviewed footage to help train AI algorithms. Tasks include categorizing vehicle makes, colors, and types, transcribing license plates, and "audio tasks." Flock recently started advertising a feature that will detect "screaming." The panel showed workers sometimes completed thousands upon thousands of annotations over two day periods. The exposed panel included a list of people tasked with annotating Flock's footage. Taking those names, 404 Media found some were located in the Philippines, according to their LinkedIn and other online profiles.

Many of these people were employed through Upwork, according to the exposed material. Upwork is a gig and freelance work platform where companies can hire designers and writers or pay for "AI services," according to Upwork's website. The tipsters also pointed to several publicly available Flock presentations which explained in more detail how workers were to categorize the footage. It is not clear what specific camera footage Flock's AI workers are reviewing. But screenshots included in the worker guides show numerous images from vehicles with US plates, including in New York, Michigan, Florida, New Jersey, and California. Other images include road signs clearly showing the footage is taken from inside the US, and one image contains an advertisement for a specific law firm in Atlanta.

The U.S. Patent and Trademark Office has issued new guidelines outlining when inventions created with the help of AI can be patented. From a report: USPTO Director John Squires said on Wednesday in a notice set to be published Friday, that the office considers generative AI systems to be "analogous to laboratory equipment, computer software, research databases, or any other tool that assists in the inventive process."

"They may provide services and generate ideas, but they remain tools used by the human inventor who conceived the claimed invention," the office said. "When one natural person is involved in creating an invention with the assistance of AI, the inquiry is whether that person conceived the invention under the traditional conception standard."

The office reiterated its guidance from last year that AI itself cannot be considered an inventor under U.S. patent law. However, it rejected the approach taken by the PTO during former President Joe Biden's administration for deciding when AI-assisted inventions are patentable, which relied on a standard normally used to determine when multiple people can qualify as joint inventors.

China's pharmaceutical industry has quietly evolved from a hub for generics and clinical trials into something more ambitious -- a genuine competitor in drug discovery that Western giants are now courting to fill gaps left by looming patent expirations worth over $300 billion by 2030. In the first half of 2025, nearly a third of global licensing agreements signed by big pharma involved Chinese firms, Economist reports, four times the share from 2021. Pfizer agreed in May to pay $1.25 billion to 3SBio for an experimental cancer drug, and GlaxoSmithKline followed in June with a deal valued at up to $12 billion with Hengrui. Chinese companies now run about a third of the world's clinical trials, up from 5% a decade ago.

An anonymous reader quotes a report from Ars Technica: Some members of the maker community are distraught about Arduino's new terms of service (ToS), saying that the added rules put the company's open source DNA at risk. Arduino updated its ToS and privacy policy this month, which is about a month after Qualcomm announced that it's acquiring the open source hardware and software company. Among the most controversial changes is this addition: "User shall not: translate, decompile or reverse-engineer the Platform, or engage in any other activity designed to identify the algorithms and logic of the Platform's operation, unless expressly allowed by Arduino or by applicable license agreements ..."

In response to concerns from some members of the maker community, including from open source hardware distributor and manufacturer Adafruit, Arduino posted a blog on Friday. Regarding the new reverse-engineering rule, Arduino's blog said: "Any hardware, software or services (e.g. Arduino IDE, hardware schematics, tooling and libraries) released with Open Source licenses remain available as before. Restrictions on reverse-engineering apply specifically to our Software-as-a-Service cloud applications. Anything that was open, stays open."

But Adafruit founder and engineer Limor Fried and Adafruit managing editor Phillip Torrone are not convinced. They told Ars Technica that Arduino's blog leaves many questions unanswered and said that they've sent these questions to Arduino without response. "Why is reverse-engineering prohibited at all for a company built on openly hackable systems?" Fried and Torrone asked in a shared statement. There are also concerns about the ToS' broad new AI-monitoring powers, which offer little clarity on what data is collected, who can access it, or how long it's retained. On top of that, the update introduces an unusual patent clause that bars users from using the platform to identify potential infringement by Arduino or its partners, along with sweeping, perpetual rights over user-generated content. This could allow Arduino, and potentially Qualcomm, to republish, modify, monetize, or redistribute user uploads indefinitely.

Tsinghua University collected 4,986 AI and machine learning patents between 2005 and the end of 2024. The Beijing institution has received more than 900 patents last year alone. The total exceeds the combined patent count from MIT, Stanford, Princeton and Harvard during the same period. China now accounts for more than half of all active patent families globally in AI and machine learning fields, according to data analytics service LexisNexis.

The university also has more AI research papers among the 100 most cited than any other school at last count. The US still holds the most influential AI patents and the top performing models. Harvard and MIT consistently rank ahead of Tsinghua in patent influence. American institutions produced 40 notable AI models in 2024 compared to 15 from Chinese organizations, according to Stanford's AI Index Report. China's share of the world's elite AI researchers -- the top 2% -- rose from 10% in 2019 to 26% in 2022. The US share fell from 35% to 28% during the same period, according to the Information Technology & Innovation Foundation.

An anonymous reader shares a report: California-based TP-Link says it may take a sales hit of more than $1 billion because of erroneous reports that the networking company's technology has been "infiltrated" by Beijing. In a lawsuit, TP-Link claims its competitor, Netgear, orchestrated a smear by planting false claims with journalists and internet influencers with the goal of scaring off customers.

Closely held TP-Link, which makes wireless routers, alleges in a complaint filed Monday that Netgear's campaign "threatens injury to well over a billion dollars in sales" and violates a 2024 settlement of a patent fight. That accord, in which TP-Link agreed to pay Netgear $135 million, includes a provision that the public company promises not to disparage its rival, according to the suit in Delaware federal court.

The suit comes as TP-Link faces growing scrutiny in Washington over national-security issues. US lawmakers from both parties have expressed concern that TP-Link's wireless equipment could be exploited by Chinese hackers following a series of attacks on its routers.

Long-time Slashdot reader theodp says America's Patent and Trademark Office (USPTO) has granted a patent to Tableau (Salesforce's visual analytics platform) — for a patent covering "Data Processing For Visualizing Hierarchical Data": "A provided data model may include a tree specification that declares parent-child relationships between objects in the data model. In response to a query associated with objects in the data model: employing the parent-child relationships to determine a tree that includes parent objects and child objects from the objects based on the parent-child relationships; determining a root object based on the query and the tree; traversing the tree from the root object to visit the child objects in the tree; determining partial results based on characteristics of the visited child objects such that the partial results are stored in an intermediate table; and providing a response to the query that includes values based on the intermediate table and the partial results."

A set of 15 simple drawings is provided to support the legal and tech gobbledygook of the invention claims. A person can have a manager, Tableau explains in Figures 5-6 of its accompanying drawings, and that manager can also manage and be managed by other people. Not only that, Tableau illustrates in Figures 7-10 that computers can be used to count how many people report to a manager. How does this magic work, you ask? Well, you "generate [a] tree" [Fig. 13] and "traverse a tree" [Fig. 15], Tableau explains. But wait, there's more — you can also display the people who report to a manager in multi-level or nested pie charts (aka Sunburst charts), Tableau demonstrates in Fig. 11.

Interestingly, Tableau released a "pre-Beta" Sunburst chart type in late April 2023 but yanked it at the end of June 2023 (others have long-supported Sunburst charts, including Plotly). So, do you think Tableau should be awarded a patent in 2025 on a concept that has roots in circa-1921 Sunburst charts and tree algorithms taught to first-year CS students in circa-1975 Data Structures courses?

Shenzhen-Hong Kong-Guangzhou has overtaken Tokyo-Yokohama to become the world's top cluster for innovation, the United Nations said Monday. From a report: The UN's World Intellectual Property Organization (WIPO) said the Chinese cluster had leapfrogged its Japanese rival in its 2025 Global Innovation Index. The change at the top of the world's 100 leading innovation clusters was down to WIPO broadening the criteria to include venture capital investments to formulate the annual rankings.

The UN agency dealing with patenting and innovation previously only used patent filing and scientific publishing data to identify local concentrations of world-leading innovation activity. "Venture capital investment activity helps capture how scientific and technological knowledge translates into start-up creation and, ultimately, new goods and services in the marketplace," WIPO said. The agency said Shenzhen-Hong Kong-Guangzhou and Tokyo-Yokohama "make a massive contribution to global scientific publications and patenting outputs", together accounting for nearly one in five patent applications filed globally.
