Biotechnology Future Investment Expansion Act of 2003

Biotechnology Future Investment Expansion Act of 2003 - Amends the Internal Revenue Code to provide that in the case of a biomedical research corporation, any owner shift involving a five-percent shareholder which occurs as the result of a qualified investment during the testing period shall be treated as occurring before the testing period. (Thus not counting toward net operating loss and tax credit carryover limitations.)

Defines: (1) "biomedical research corporation" as a domestic corporation not in bankruptcy which has a drug or biologic in certain clinical trials; and (2) "qualified investment" as a stock acquisition in a biomedical research corporation acquired in cash at its original issue.

Requires a biomedical research corporation to meet a five-year expenditure test with respect to any qualified investment.
