Patent Wars Come to India as Tracker firms slug it out in US courts
GameChange Energy sued Nextpower on September 9 in the US District Court for Delaware, alleging that Nextpower’s NX Horizon with Hail Pro tracker infringes a GameChange patent covering “self-shielding” trackers. These are  arrays that rotate panel rows to 60-80 degrees from horizontal when wind speeds cross 70 mph, protecting the modules from storm damage. The patent, US-12449161-B2, was granted to GameChange in October 2025.
It is the second such lawsuit in three months between the same two companies, and between them they account for a large share of the world’s non-Chinese origin tracker shipments. In June, Nextpower,  the market leader by sales, according to Wood Mackenzie, formerly known as Nextracker filed first, accusing GameChange’s Genius Tracker line and its TrueCapture-adjacent control software of infringing three of its own patents on self-powered tracking hardware. GameChange has denied that claim and says it will “mount a full and vigorous defense.”
Rebrand, then litigate
Interestingly, both lawsuits have landed alongside corporate repositioning by the firms involved. GameChange folded its tracker, transformer and electrical balance-of-system divisions into a single GameChange Energy brand this year; Nextpower dropped the Nextracker name altogether as it pushed into module frames, power conversion and storage. Executives on both sides framed the shift as a natural vertical integration to becoming full energy-infrastructure platforms rather than single-component suppliers.
The lawsuits indicate a second motive: as tracker margins compress and product lines converge, patents on incremental mechanical tweaks, a tilt angle here, a wind-stow algorithm there,  are being used as competitive weapons rather than just protective filings. Industry watchers have already flagged a parallel wave of TOPCon cell-technology litigation among Chinese and US manufacturers this year; tracker “lawfare” looks like the same instinct arriving in a different product category.
Where India fits
GameChange began construction last month on a transformer manufacturing facility in India in a bet that the country’s utility-scale pipeline needs more locally built balance-of-system hardware, not just modules and cells. It arrives at an interesting moment for that bet. Both litigants sell into India; Nextpower has long supplied trackers to large Indian IPPs, and GameChange’s own tracker and BOS lines compete for the same tenders. Neither company has extended its patent fight into an Indian court yet, and there is no indication either intends to. But the dispute is still a preview of a risk India’s tracker and BOS manufacturing base,  still relatively nascent compared with its module and cell capacity might  have to price in as it scales: mechanical tracking IP, unlike cell efficiency IP, is granular enough that a single tilt-angle claim can cover a huge share of the deployed base.
A tilt angle is a strange thing to fight over in court,  until you remember that trackers, not modules, are where the two largest global suppliers now compete hardest.
For Indian developers and EPCs, the near-term effect is likely to be limited as component sourcing decisions rarely count on litigation risk in a market run by pricing. The longer-term one is more real: as more tracker and BOS content gets manufactured domestically under ALMM-style localisation pressure, Indian component makers inherit exposure to the same patent skirmishes that are now colliding in Delaware. A domestic tracker industry that wants to avoid simply relicensing foreign IP will need the same freedom-to-operate diligence GameChange and Nextpower are now litigating the hard way.
