Nextpower files a patent infringement lawsuit against GameChange Energy in the US District Court for the District of Delaware. Nextpower alleges that GameChange Energy infringes three of its patents connected to solar tracker technology and software. The complaint asserts that GameChange’s actions fall within the scope of the patents at issue, though specific claim details are not provided in the available summaries. GameChange Energy responds by denying the infringement allegations. In a statement, the company says it is aware of the lawsuit and plans to mount a full defense against Nextpower’s claims. The parties therefore head into litigation centered on whether GameChange’s tracker and related software technology infringes the three patents cited by Nextpower. At this stage, the dispute is limited to the filing and the companies’ initial positions: Nextpower alleges infringement, while GameChange denies it and indicates it will defend itself in court. No ruling or settlement outcome is reported in the provided sources.
