TP-Link, a California-based networking company, has filed a lawsuit against its rival, Net, alleging that Netgear orchestrated a smear campaign by spreading false claims about its technology being infiltrated by Beijing. The company claims this campaign could lead to a potential sales loss of over $1 billion and breaches a 2024 patent settlement agreement, which required Netgear not to disparage its rival. The lawsuit, filed in Delaware federal court, highlights the ongoing tensions between the two companies and the broader implications of cybersecurity concerns in the industry.
