Kathy, a serial entrepreneur, was negotiating the acquisition of a boutique software-development firm when a dispute arose regarding the valuation of one of the software firm’s assets. Specifically, the firm owned the rights to a technology patent of uncertain value. The firm’s owner argued that this patent was worth millions. Kathy agreed that the patent had potential, but there was a problem. The technology potentially infringed on existing patents, and the holders of these patents would almost certainly challenge the firm’s patent in court. If the patent could withstand these legal challenges, it would indeed be worth millions. If not, it might be worthless.
