Safiya Aguilar is a former Patent Trial and Appeal Board (PTAB) law clerk and patent examiner at the U.S. Patent and Trademark Office (USPTO). She uses her extensive knowledge of patent office practice to help firm clients navigate post grant proceedings and various aspects of pre-trial preparation, including validity and infringement analyses.

Safiya’s technical knowledge covers a broad spectrum of complex technologies, including medical devices, image and video processing, distributed computing, data communication networks, wireless communication devices,  graphical user interfaces, biometric authentication, inductive coupling, navigation, machine vision, feedback controls, fuel cells,  fintech, and additive manufacturing. She has experience preparing petitions for inter partes review (IPR) and requests for ex parte reexamination, as well as conducting legal and factual research in support of infringement and invalidity disputes. 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.

Safiya devotes a portion of her time to pro bono matters. She has worked extensively with asylum-seeking clients and advocated on behalf of inmates seeking compassionate release over the course of the COVID-19 pandemic. She has been recognized on the Capital Pro Bono Honor Roll and received high honors.

Experience

Stragent, LLC v. BMW et al.

Obtained a royalty-free license to Stragent’s entire patent portfolio after forcing Stragent to concede in open court that it could not present enough evidence to prove infringement of its asserted patents, which Stragent read on the automotive communications standard AUTOSAR. Successfully invalidated multiple of Stragent’s patents before the Patent Office, with one victory on appeal and additional IPR petitions pending at the time of case resolution.

NorthStar Systems LLC v. BMW et al.

Secured a royalty-free covenant not to sue from NorthStar for its present and future patent portfolio, which includes patents related to displaying navigation information on electronic maps, mobile devices selectively reporting GPS position information to others, and route-based communication planning architecture and wireless communication. This result was achieved after filing a declaratory judgement as well as IPRs on all claims of all asserted patents, leading to favorable institution decisions.
