• Proactively advise clients on IP strategy aligned with business objectives, including portfolio positioning and competitive landscape, preferably using AI-enhanced portfolio analytics, competitive intelligence, and predictive modeling, and translating complex data into actionable business recommendations.

• Provide patentability evaluations of IP related to internal research programs and external business development opportunities.

• Conduct, direct, and analyze patent searches; render written opinions on validity, non-infringement, and freedom-to-operate / design-around of third-party patents.

• Initiate, defend, and manage post-issuance proceedings, including US Inter Partes Review (IPR), Post-Grant Review (PGR), EPO Oppositions, and patent litigation support.

• Review proposed research papers and other publications for potential impact on Sanofi's existing patent estate.

• Participate in the drafting, reviewing, and negotiation of agreements covering intellectual property rights (licenses, CDAs, collaboration agreements, etc.)

• Leverage AI tools strategically across the full patent lifecycle  including AI-assisted drafting, claim analysis, prior art searching, office action response preparation, and portfolio analytics  while maintaining critical oversight, professional judgment, and work product quality control.

• Critically review and validate all AI-generated work products to ensure technical accuracy, legal soundness, strategic alignment, and freedom from hallucinations or analytical errors before client delivery or filing.

• Direct AI-assisted workflows for patent prosecution streams, configuring AI tools to execute within defined strategic parameters while maintaining appropriate human oversight for privilege, risk management, and client accountability.

• Develop custom AI tools and workflows to address emerging needs in patent prosecution, IP strategy, or portfolio management including prompt engineering, automation of routine analysis, and creation of bespoke intelligence tools (e.g., examiner behavior analysis, art unit trend mapping) without waiting for vendor or IT solutions.

• Collaborate with cross-functional teams to identify opportunities for AI augmentation of IP processes, pilot new AI capabilities, and share best practices for responsible and effective AI integration across the Global IP organization.

• Maintain professional accountability and licensed judgment as the human decision-maker in all AI-augmented work, ensuring that AI serves as a force multiplier for strategic thinking rather than a substitute for legal expertise or client counseling.

• Serve as a thought leader within the Global IP team on responsible AI adoption, sharing insights on effective AI integration, emerging risks, and evolving best practices for AI-augmented patent practice.

• Develop and maintain an effective professional network within Sanofi's Biologics Business Units and Global IP group.
