Today, district courts evaluate whether patent infringement complaints satisfy the plausibility standard under Fed. R. Civ. P. 8 and the Supreme Court’s Iqbal–Twombly standard. Five years after abrogation of Form 18 (a sample patent infringement complaint that was said to be plaintiff-friendly) and nearly 15 years after Twombly, jurisdictional analyses have diverged. Fed. R. Civ. P. 12(b)(6) and 12(c) motions have developed into a targeted, widely-used tactic. Both motions provide defendants with a low-risk, high-reward opportunity. As plaintiff or defendant, start by evaluating the possible-to-plausible pleading spectrum.
