Safiya advises clients on all aspects of patent strategy, including validity opinions, landscape analysis, due diligence, and prosecution.
As a judicial law clerk, Safiya assisted administrative patent judges (APJs) with adjudicating America Invents Act (AIA) trials and ex parte appeals across chemical, electrical, mechanical, and pharmaceutical technologies. During her more than seven years as a patent examiner, Safiya evaluated the patentability of various medical devices, including spinal implants and prosthetics; image-guided and robotic surgical systems; internal and external fixation devices; and retractors.

She has been recognized on the Capital Pro Bono Honor Roll and received high honors.
