About the Job

Requirements

  • A Juris Doctor degree, active membership in good standing in at least one US state bar, and registration to practice before the United States Patent and Trademark Office.
  • At least eight years of broad patent experience in life sciences, with demonstrated success building complex portfolios and developing and executing patent strategy.
  • A genuine, demonstrable appetite and curiosity to help drive an evolving agentic intellectual property team; willingness to learn emerging artificial intelligence capabilities, question established processes, experiment responsibly, and help colleagues adopt better ways of working.
  • Strong legal and business judgment; ability to explain complex issues clearly, make practical recommendations, and collaborate effectively across scientific, commercial, and legal teams.

Responsibilities

  • Develop creative, business-aligned protection and enforcement strategies; build and manage global portfolios and oversee patent preparation, filing, and prosecution in the United States, Europe, and other key jurisdictions throughout the world.
  • Act as strategic intellectual property partner to global project teams responsible for key drug candidates across the portfolio; translate complex science and patent issues into clear recommendations that support product development, commercialization, and long-term portfolio value.
  • Work with scientists to identify and protect inventions, assess inventorship, manage public disclosures, and strengthen trade secret protection.
  • Conduct infringement, validity, freedom-to-operate, and competitive landscape analyses, identifying actionable risks and opportunities.
  • Lead patent-related diligence and support licensing, collaborations, partnerships, mergers, and acquisitions; review, draft, and negotiate intellectual property provisions and agreements, including confidentiality, technology transfer, and licensing arrangements.
  • Strengthen litigation readiness and lead or support patent disputes in coordination with the internal team and external counsel; connect prosecution, records, and enforcement strategy.
  • Manage external counsel and business partners, align priorities and resources, and deliver portfolio reviews, long-range planning, and special projects.
  • Help design and pilot approved agent-assisted workflows for request intake, patent monitoring, diligence preparation, portfolio reporting, and knowledge retrieval; start with bounded use cases and improve them through feedback.
  • Define tasks, authoritative inputs, review checkpoints, and escalation rules; verify outputs and references, protect confidential and privileged information, respect data-use restrictions, and retain attorney accountability for legal advice and consequential decisions.
  • Partner with intellectual property operations, technology, and other colleagues to turn useful pilots into repeatable practices; share learning, coach colleagues, and assess improvements in quality, responsiveness, and capacity, not simply tool usage.

Desired Qualifications

  • Large-molecule experience.
  • An advanced life sciences degree, preferably at least a thesis-based master's degree in biology or a related field.
  • Both law firm and in-house experience; biosimilar or generic litigation; licensing and transactional diligence. Law firm-only candidates, particularly those with intellectual property litigation experience in addition to portfolio building, will also be considered.
  • Rare-disease and small-molecule experience.
  • Experience improving legal workflows or using artificial intelligence, automation, or knowledge tools. Prior agent-building experience and coding skills are not required; learning agility, sound judgment, and willingness to experiment are essential.
