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.

Rule 144 notice regulatory
"Information is to be given not only as to the person for whose account the securities are to be sold"
A Rule 144 notice is a public filing that an insider or holder of restricted stock submits when they plan to sell shares that aren’t freely tradable yet; it lists how many shares they intend to sell and under what conditions. For investors, it matters because it signals potential insider selling and an upcoming increase in shares available to the market—similar to someone announcing a big garage sale, which can affect supply and price expectations.
