JinkoSolar has initiated a legal action against Waaree Energies for patented technology

JinkoSolar has filed an infringement against Waaree Energies and its U.S. based subsidiary, Waaree Solar Americas, alleging infringement of its n-type tunnel oxide passivated contact (TOPCon) patent number, US11,824,136B2 granted in 2023. It is filed in the U.S. District Court for the Southern District of Texas on February 7, 2025.

The above said patent is granted to JinkoSolar in 2023, pertains to solar cells, their manufacturing methods, and photovoltaic modules. JinkoSolar has also patented this technology in key global markets, including China, Japan, Australia, and the European Union.

Now a days, this legal action is part of a broader trend in the solar industry, where major manufacturers are actively defending their intellectual property rights related to advanced technologies like TOPCon. For example, Trina Solar has recently filed a lawsuit against Canadian Solar over alleged patent infringements concerning TOPCon cell technologies.
Waaree Energies, is India’s largest solar PV module manufacturer. It is the flagship company of the Waaree Group, founded in 1989. It operates four PV manufacturing facilities in Gujarat, India, with a combined capacity of almost 12 GW. In December 2024, Waaree Solar Americas began producing solar modules at its new 1.6 GW plant in Brookshire, Texas
The outcome of this lawsuit could have significant implications for the solar industry, particularly concerning the protection and commercialization of IP rights related to advanced photovoltaic technologies.

 

“Ratan Tata” is a well-known trademark: Delhi High Court

The recent judgement issued by Delhi High Court on February 7 says that the name “Ratan Tata” is a well-known trademark which needs to be protected as per law.
Justice Mini Pushkarna made the observation while hearing a trademark suit filed by Tata Group and Sir Ratan Tata Trust against misusing the Tata brand, trademarks and the name of late Ratan Tata. [Sir Ratan Tata Trust Vs Dr. Rajat Srivastava].
On February 7, 2025, the court prohibited Rajat Srivastava, from hosting an event under the name “Ratan Tata Icon Award.” The court also restricted him from using the name and photograph of the late Ratan Tata for any purpose, including conferring any awards. The judgement is to protect the reputation and legacy of Ratan Tata, a highly respected business figure and philanthropist. The injunction likely stems from concerns over the misuse of his name and image in a manner that could potentially mislead or cause confusion about his endorsement of such events.
Generally, a well-known trademark is a mark that has achieved such a high degree of recognition among the public. It’s a mark that’s so famous and recognizable that its mere presence evokes the brand in the minds of consumers.
The lawsuit filed by Tata Group and the Sir Ratan Tata Trust emphasized the long-standing reputation and legacy of the Tata name, which has been a symbol of trust, quality, and ethical business practices in India for over 150 years. They argued that the unauthorized use of the Tata name and Ratan Tata’s image, particularly in the organization of events and awards, misled the public into thinking the Tata entities were endorsing them.
Rajat Srivastava and his organization, allegedly exploited the Tata brand’s goodwill by charging nomination fees for the event and promoting it across social media platforms. This created confusion among the public, making them believe the event was connected to or endorsed by the Tata Trusts. Despite the Tata Trusts issuing a takedown notice to stop such promotions, the defendants allegedly continued advertising the event, prompting the legal action.
The court ruled in favor of the Tata Group and the Sir Ratan Tata Trusts, granting them a permanent injunction against Rajat Srivastava and his organization. This means that the defendants are now permanently prohibited from using the Tata name, trademarks, or Ratan Tata’s image in any future events, promotions, or activities. However, the court directed the defendants to file an affidavit confirming their commitment to not engage in such activities going forward.
While the plaintiffs, Tata Group and the Tata Trusts, expressed satisfaction with the court’s ruling, they chose to waive any claims for damages or legal costs. This decision emphasizes that their main focus is on protecting the integrity of the Tata brand and preventing future misuse, rather than seeking any financial compensation.
