Arianne E. Rodriguez, Ph.D.

Scientific Advisor & Patent Agent

To further client goals, Arianne uses her research background and analytical skill to provide intellectual property support.

Arianne is a biologist and chemist who has researched, taught, and published in her field of biological sciences. Working closely with legal teams, she serves as a translator and analytical problem solver, primarily in the patent litigation sector. Arianne has experience in preparing Paragraph IV filings for generic versions of branded drugs, as well as research and analysis experience when PIV filings are challenged. Her research often leads to a victory or settlement, resulting in getting generic drugs to market faster and saving litigation costs for clients.

If a patent challenge results in litigation, Arianne serves clients by using her scientific knowledge to assist in discovery, design third party testing if needed, work with expert witnesses in testimony preparation, and confer with litigation attorneys to offer further insight to inform their questioning and arguments.

Arianne also has experience in patent prosecution for clients in the medical and chemical fields, frequently drafting applications, responding to office actions, and providing guidance to clients on the patent process. Arianne has experience in patent prosecution of patents involving polymers, medical devices, genetic modulatory compositions, and chemical formulations both industrial and pharmaceutical.

Attorneys and clients appreciate Arianne’s excitement, passion, attention to detail, and interest in industry commercialization as well as her ability to proactively bridge gaps when the law intersects with issues of biology and biochemistry. Arianne is also an avid advocate for outreach and professional development for women and Latines in STEM.

She assists across a wide range of phases and matters, including:

  • Intellectual property matters
  • Due diligence
  • Discovery
  • Patent infringement
  • Patent prosecution
