Her most significant winning arguments include a U.S. Supreme Court reversal worth billions of dollars for unionized employers in the Sixth Circuit; a U.S. Supreme Court reversal limiting the power of federal regulators; a multi‐billion dollar environmental win in the Fifth Circuit; a multi‐billion dollar commercial victory for the founder of a technology company in the Appellate Division of the New York Supreme Court; a billion dollar environmental win in the Houston Court of Appeals; a nine‐figure commercial victory in the Corpus Christi Court of Appeals; and a nine‐figure arbitration win in the Fifth Circuit.
Among her numerous accolades, Mrs. Ho is one of only a small group of appellate lawyers nationwide, and the only one in Texas, to be nationally ranked by Chambers every year for the past ten years (2012‐21).

Federal and State Appellate Practice
Mrs. Ho has argued a series of high stakes, landmark cases on behalf of the business community before the U.S. Supreme Court.

She also prevailed against the EEOC in a case that the employment defense bar called “good news for employers across the country.” And in “the most important patent case in modern history” according to patent law experts, her argument before the Court was credited for “pick[ing] up two votes that pundits thought unreachable.”
She has appeared before every federal court of appeals in the country, including en banc arguments before the Fourth and Sixth Circuits. She has successfully represented business clients in every circuit, including the First (Pruco Life Insurance Company), Second (Swiss Federation; Rite Aid), Third (Johnson & Johnson), Fourth (Genex Services), Fifth (United Space Alliance LLC; Elliott Co.; MERSCORP; 24 Hour Fitness USA, Inc.; Stream Energy; Health Management Systems), Sixth (Deutsche Bank; American Airlines; M&G Polymers), Seventh (Expedia), Eighth (Cotter), Ninth (Boeing; JP Morgan Chase Bank), Tenth (Mitchell International), Eleventh (AstraZeneca), D.C.
