Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

RSU Vesting financial

"Common Stock | 05/12/2022 | RSU Vesting | Acacia Research Corporation"

RSU vesting is the process by which restricted stock units — a promise by a company to give shares to an employee — become actual, owned shares over time or when certain goals are met. Investors care because vested shares can dilute existing ownership when issued, and the timing of vesting affects when employees can sell shares, which can influence share supply, insider selling patterns, and company incentives.

attorney-in-fact regulatory

"as attorney-in-fact for Maureen E O'Connell"

An attorney-in-fact is the person or entity given legal authority through a power of attorney to act on behalf of another for specific tasks, such as signing documents, voting shares, or handling transactions. For investors, this matters because it lets a trusted representative make timely decisions or complete paperwork when the owner cannot, much like handing keys to someone to run errands on your behalf—so checks on scope and limits of that authority are important.
