Google has already invested in expressive watch faces with adaptive colors and animations. However, the new patent hints at a leap forward—one where every Pixel Watch could feature a completely different look, designed in real time by AI.

This could open possibilities such as:

  • Personal mood-based faces that shift colors during the day.
  • Fitness-aware faces that adjust visuals after a workout.
  • Seasonal or event-driven themes, auto-generated by AI.

Not Guaranteed Yet

While the patent reveals exciting potential, it does not confirm an official product. Tech companies often patent innovations that never reach consumers. Still, the timing suggests Google may be preparing to bring more AI-driven personalization to its wearable ecosystem.

Conclusion

If realized, this feature would make the Pixel Watch a showcase for on-device AI creativity. With Wear OS 6 and Gemini on the horizon, the smartwatch may soon become as much about personal expression as it is about fitness tracking and notifications.

Parliamentary Panel Pushes for Patent Commercialisation Hubs in IITs

by

A Parliamentary panel has recommended the creation of Patent Commercialisation Hubs at Indian Institutes of Technology (IITs) to transform academic research into market-ready products. The proposal comes from the Parliamentary Standing Committee on Commerce in its 192nd report, highlighting the need to strengthen India’s intellectual property ecosystem.

Bridging the Innovation Gap

The committee noted that while India has seen a surge in patent filings from universities and research institutions, many innovations remain unutilised. By setting up these hubs, IITs can provide infrastructure, mentorship, and technical guidance to convert patents into viable products.

The panel also urged the government to introduce matching grants for innovators. These grants would help researchers and startups build prototypes, making their technologies attractive for industry partnerships.

Incubation and Investor Linkages

The report suggested establishing Patent-to-Product Incubation Centres at IITs. These centres would offer seed funding, lab facilities, and business mentorship. More importantly, they would connect innovators with venture capitalists and private investors, ensuring that promising technologies scale effectively.

Government’s Current Measures

The Ministry of Commerce pointed out several existing initiatives. The Indian Patent Advanced Search System (inPASS) allows stakeholders to explore patents and identify potential licensing opportunities (inPASS). Patent holders can voluntarily declare their willingness to license inventions, helping industries adopt innovative solutions.

Additionally, the government has slashed patent renewal fees by 80% for startups, MSMEs, and educational institutions. This step reduces financial pressure on smaller innovators and promotes long-term patent protection.

Why It Matters

India’s educational institutions filed over 19,000 patents in FY 2023, accounting for 23% of total filings. This marks a sharp rise from 7,200 in FY 2022. Yet, challenges such as long patent approval timelines—around 51 months—continue to hamper innovation.

The proposed hubs can bridge this gap by ensuring patents are not just filed but also commercialised. Such efforts could position India as a stronger global player in innovation.

Outlook

If implemented, these hubs could redefine India’s innovation ecosystem. IITs, with their research capabilities and industry linkages, are well-placed to lead this initiative. The move aligns with India’s ambition to strengthen its intellectual property rights (IPR) regime and drive economic growth through technology-driven enterprises.

Hyundai Patents Breakthrough for Copper Use in Solid-State Batteries

by

Hyundai has secured a U.S. patent for a new method that makes copper usable in sulphide-based solid-state batteries. The patent was published on August 18, 2025.

Copper is widely used in conventional lithium-ion batteries as an anode current collector. It offers high conductivity and low cost. But in solid-state batteries, copper has been avoided. The sulphide electrolytes corrode copper, forcing manufacturers to use alternatives like nickel or stainless steel. These materials are more expensive and less conductive.

Hyundai’s patent changes this equation. The company developed a protective coating that shields copper from corrosion. The design uses a carbon sheet combined with vertically aligned carbon nanotubes. It also integrates lithiophilic metal particles such as silver, aluminum, or gold. This layer enhances durability and ensures stable adhesion.

The new structure allows copper to survive repeated charge and discharge cycles. It maintains strong conductivity and prevents capacity loss. This breakthrough could reduce battery costs and improve performance for electric vehicles.

Hyundai has been pushing aggressively in solid-state battery research. In 2023, it filed another patent for a system that maintains constant pressure in battery cells. In January 2025, the company confirmed plans for a pilot production line. Mass production is expected around 2030.

The global race for solid-state battery technology is intense. Automakers see it as the next leap beyond lithium-ion. Solid-state batteries promise higher energy density, faster charging, and improved safety. Companies like Toyota, Volkswagen, and Stellantis are also working on similar solutions.

Hyundai’s copper breakthrough strengthens its position in this race. By combining low-cost materials with long-term stability, the company could lower barriers to mass adoption of solid-state EV batteries.

Delhi High Court Suggests Zee Media Consider Logo Change in “Duniyadari” Trademark Dispute

by

The Delhi High Court has advised Zee Media Corporation to consider altering its logo in an ongoing trademark dispute with the India Today Group. The case revolves around the title “Duniyadari,” which both media houses are using for their news shows.

The Dispute

India Today Group, through its digital platform The Lallantop, has been running a popular show called Duniyadari since 2020. The programme attracts millions of views, with some episodes crossing 8.5 million views. The company claims strong goodwill and recognition for the mark.

Zee Media launched a Punjabi-language show with the same title, written in Gurmukhi script. India Today alleged that the use of “Duniyadari” in any form amounts to infringement and passing off, even after Zee removed a globe symbol from its logo.

Zee’s Argument

Zee Media argued that “Duniyadari” is a common Hindi expression that means “worldly affairs.” It said no company can monopolise such a generic term. The broadcaster further stressed that India Today’s registration covers only a stylised label and not exclusive rights to the word itself. Zee also referred to the 2013 Marathi film Duniyadari as proof that the term has long been in public use.

Court’s Observations

Justice Tejas Karia noted that the similarity between the two marks could confuse viewers who can read both Hindi and Gurmukhi. He said the marks appeared “prima facie deceptively similar.” The judge suggested that Zee could consider changing its logo if it wished to avoid prolonged litigation. However, he clarified that this was not a final ruling.

Next Steps

The Court directed Zee Media to file its reply by August 22, 2025. The matter will be heard again on September 2, 2025.

India Today expressed openness to resolve the matter through negotiation but maintained that Zee must stop using the “Duniyadari” mark if a settlement cannot be reached.

The case highlights the growing conflicts in India’s media industry over trademark ownership, especially when popular content crosses into multiple languages and regions.

India Plans Major Overhaul of Intellectual Property Laws

by

Commerce and Industry Minister Piyush Goyal has signalled a sweeping reform of India’s intellectual property (IP) framework. The government aims to simplify laws, speed up processes, and create new avenues for commercial use of registered rights.

Goyal said the government is open to introducing new laws and making amendments where needed. He added that officials will study how trademarks can be better leveraged for revenue and economic growth.

The minister highlighted that India’s IP ecosystem has made significant progress in recent years. Patent grants have risen sharply. Trademark filings have also surged, making India the sixth-largest filer worldwide. Yet, Goyal acknowledged that trademark registration timelines remain long and need to be reduced.

The reforms come after the Jan Vishwas (Amendment of Provisions) Act, 2023 took effect on August 1, 2024. The law decriminalised several minor IP offences and replaced prison terms with monetary penalties. It also introduced a 10% automatic increase in fines every three years.

To boost efficiency, the government recently launched AI- and machine-learning-based tools for trademark searches. The new IP Saarthi chatbot offers guidance in local languages, making the process more accessible to entrepreneurs and small businesses.

Goyal stressed that technology will play a central role in modernising IP administration. Faster examinations, digital tools, and better enforcement mechanisms will help India attract innovation and investment.

He also pointed to the potential of monetising trademarks. While he did not give details, experts say this could involve licensing, brand valuation, and broader commercial use of registered marks.

The push to ease compliance is part of the government’s broader plan to cut outdated rules. According to Goyal, many provisions are redundant and create unnecessary burdens for businesses.

India’s reforms aim to balance protection of rights with ease of doing business. If successful, they could position the country as a global leader in IP administration and innovation-driven growth.

German Firm ParTec Sues Nvidia, Seeks AI Hardware Ban Across 18 European Countries

by

German supercomputing specialist ParTec AG has launched a fresh legal offensive against U.S. chip giant Nvidia, filing a patent infringement lawsuit at the Unified Patent Court (UPC) in Munich. The company aims to secure an injunction that would block the sale of Nvidia’s DGX AI supercomputers in 18 European countries.

ParTec alleges that Nvidia copied its patented dynamic Modular System Architecture (dMSA), a design that enables real-time coordination between CPUs and GPUs for high-efficiency AI computing. According to the filing, the technology is central to modern supercomputing performance and powers some of Europe’s largest AI installations.

The lawsuit marks the third patent dispute ParTec has initiated against Nvidia. The company has also demanded that Nvidia disclose detailed sales figures for the DGX line and pay damages for the alleged infringement.

Collaboration Talks Turned Sour
ParTec claims the dispute began in 2019, when it shared details of its dMSA technology and ParaStation software with Nvidia during discussions about a potential partnership. Despite initial interest, the two firms never formalized an agreement. ParTec says Nvidia later integrated the patented design into its DGX systems without permission.

Nvidia continued to supply GPUs to supercomputing projects linked to ParTec, but the German company argues that the absence of a licensing deal made such use unlawful. ParTec also suggests Nvidia’s reluctance to negotiate may stem from its earlier patent case in Texas against Microsoft, one of Nvidia’s largest customers, over the same technology.

Legal and Market Stakes
If the UPC grants the injunction, Nvidia could be forced to redesign its AI hardware or strike a licensing deal with ParTec before re-entering these 18 European markets. The outcome could disrupt Nvidia’s dominance in AI infrastructure across the region and set a precedent for enforcing European technology patents against major U.S. firms.

ParTec’s legal representative, BF exaQC AG, emphasised that protecting Europe’s home-grown innovations is essential for the continent’s technological sovereignty. “Our inventions power some of the most advanced supercomputers in Europe. We have a duty to defend them,” a company spokesperson said.

The Unified Patent Court’s ruling will carry weight well beyond this dispute. As one of the first high-profile AI hardware cases before the UPC, it could shape how Europe balances innovation protection with global competition in the race for AI supremacy.
