A former rising star in the intellectual property practice of WilmerHale has resigned from the bar after admitting to a litany of misconduct, including falsifying expense reports, forging client signatures and assigning associates to perform “pro bono” work for friends and family.

William P. DiSalvatore, who resigned his position as a partner in WilmerHale’s New York office in January, offered to resign from the bar in May as he was facing a disciplinary investigation that would have likely led to his disbarment.
