Biogen, Inc.Last week, the California Supreme Court established two new pleading rules in Ixchel Pharma, LLC v. Biogen, Inc., 2020 DJ-DAR 8084 (Aug. 3, 2020). For claims of tortious interference with at-will contracts, plaintiffs now must plead facts showing the defendant’s conduct was itself illegal, apart from the “interference.” For claims that certain non‑compete contracts between businesses violate Business and Professions Code Section 16600, plaintiffs must plead facts suggesting the contracts were anticompetitive under the “rule of reason” standard.
