Patent wars have been a mainstay of the modern technology era, with some of the world's biggest companies embroiled in high-profile tête-à-têtes, from Apple vs. Samsung, Qualcomm and Nokia, to Google vs. Sonos, Twitter vs. IBM and many more. This is one fear that's emerging in the aftermath of OpenText's $6 billion acquisition of Micro Focus, a deal that closed six months ago. OpenText is no stranger to patent assertion, and it has already been accused of behaving like a patent troll in the wake of its 2019 acquisition of data security firm Carbonite -- a deal that has led to ongoing patent litigation proceedings against CrowdStrike, Kaspersky, Sophos, and Trend Micro.
