Colleen V. Chien
90 Texas L. Rev. 283
In this article, Professor Colleen Chien examines if, and to what extent, a patent’s acquired characteristics can be used to determine whether that patent is likely to end up in litigation. Although only around 1% of patents are ever litigated, patent lawsuits are disruptive and costly. Furthermore, their unpredictability makes patent litigation a practically uninsurable risk, causing companies to expend valuable resources accumulating patents that they believe might be asserted against them in the hope of preventing future litigation. To determine whether a patent’s acquired characteristics—those qualities that a patent develops after its issuance—can be used to enhance the predictability of patent litigation, Chien examines the relationship between eventual litigation and several acquired characteristics: changes in ownership, continued investment in the patent by the owner, collateralization, and citation to the patent.
