## How this tracker works

We add a case when a company discloses it in an SEC filing, when a court record or SEC release names it, or when a law firm announces a suit that has actually been filed, with a court and case number. Investigation notices with no filed case are left out. Law-firm claims are allegations, not findings. Every row links our story, and every story links the filing, court record or release it is based on. Something missing or wrong? [Tell the editors](https://aibio.space/reputation/#correction).

News, not investment advice. [How we work](https://aibio.space/disclosures/).
