Investor Protection Act of 2002

Investor Protection Act of 2002 - Amends the Securities Exchange Act of 1934 regarding liability standards in private securities litigation to repeal: (1) the scienter requirement limiting joint and several liability for damages to covered persons who knowingly committed a violation of the securities laws; and (2) the allowance of proportionate liability, under which a covered person is liable solely for the portion of a judgment that corresponds to the person's percentage of responsibility for a securities violation. (Thus makes any covered person against whom a final judgment is entered in private securities litigation liable for one hundred percent of damages jointly and severally, even if the securities violation was not committed knowingly.)

Deems any person that recklessly provides substantial assistance to (aids or abets) another person in violation of Federal securities laws to be in violation of such laws to the same extent as the person to whom such assistance is provided.

Establishes a statute of limitations for an implied private right of action of: (1) five years after an alleged violation occurred; or (2) three years after it was discovered.

Repeals the prohibition against all but specified types of private class actions alleging either misrepresentation or omission of a material fact or manipulative or deceptive practices in connection with securities sales or purchases (thus permitting private class actions without limitation).
