About the job
Barnes & Thornburg LLP is seeking an associate with 1–4 years of life sciences patent prosecution experience to join its Intellectual Property Department. The associate will work alongside a nationally respected and growing life sciences patent team. You will help sophisticated clients protect and use innovations at the frontier of pharmaceuticals, specialty chemicals, and ag-biotech technologies.
The ideal candidate has an advanced degree in organic chemistry and will have hands-on experience in U.S. and foreign prosecution and an interest in the strategic side of patent practice, including global portfolio development, IP due diligence, patentability, and freedom-to-operate work. You will work directly with clients and inventors, take on meaningful responsibility early, and see that responsibility grow with your judgment and client relationships.
Key Responsibilities
- Patent preparation and prosecution: Draft and prosecute U.S. and international patent applications covering small molecule pharmaceuticals, specialty chemicals, ag-bio treatments, formulations, synthetic processes, and related life sciences technologies. This includes handling PCT and foreign filings in coordination with foreign associates.
- Inventor and examiner engagement: Conduct inventor interviews to capture and frame inventions. Prepare well-reasoned responses to Office Actions, and take part in examiner interviews and appeals as appropriate.
- Portfolio strategy: Working with clients and supervising attorneys, develop prosecution and global filing strategies that match patent protection to clients' scientific, commercial, and competitive goals.
- Strategic analyses: Conduct and support patentability, freedom-to-operate, validity and invalidity, and non-infringement analyses. You will turn complex technical, legal, and commercial issues into clear, actionable advice.
- Transactional and diligence support: Assess patent portfolios for financings, licensing, and M&A transactions, and help draft and review related opinions, agreements, and client correspondence.
- Client and team collaboration: Work closely with in-house counsel, R&D scientists, and internal colleagues across the firm's IP, corporate, and litigation practices.
- Growing ownership: Take on more responsibility for matters and client-facing workstreams over time, with the mentorship and support to grow into a trusted advisor.
