About Eric
Eric Estadt blends technical training and legal training in a practice centered on intellectual property. He came to law after studying engineering. The combination shapes how he handles patent work and how he speaks with inventors, engineers and in-house counsel.
Estadt earned a J.D. from DePaul College of Law in 2013. Before law school he completed a B.S. in Bioengineering at the University of Pittsburgh in 2010. That scientific background shows up in his day-to-day work. It gives him the vocabulary to parse technical disclosures and to draft patent applications that are grounded in the underlying science.
He began his post-law-school patent career in 2014 at IpHorgan Ltd., where he worked as a lawyer counseling clients on patent matters. The role put him squarely in the draft-and-prosecute side of patent practice, handling filings and responses before patent offices and advising clients about potential claim scope. In 2022 he moved to Carlile Patchen & Murphy LLP. There he continued patent prosecution and expanded his involvement in portfolio development and opinion work for clients in life sciences and medical device sectors.
Estadt is admitted in Illinois and Ohio and is registered to practice before the United States Patent and Trademark Office. Those credentials reflect a practice that straddles state bar work and federal patent practice. He draws on both kinds of authority when preparing filings, responding to office actions, and advising on clearance and enforcement risks.
Colleagues describe his approach as practical and detail-oriented. He prioritizes clear claim language and straightforward advice. That often means walking inventors through prior art issues, helping refine claims to highlight inventive features, and drafting specifications that support a broad but defendable scope. He also prepares patentability and freedom-to-operate opinions when clients need an analytical view of risk before product launches or licensing discussions.
Outside of filings and opinions, Estadt assists clients in managing prosecution timelines and in making strategic choices about where to seek protection. He works with startup founders and established companies alike, translating technical concepts into the legal mechanics of patents. His practice is concentrated on matters that intersect engineering and biology, especially medical device and biotechnology inventions.
He currently practices at Carlile Patchen & Murphy LLP, handling patent prosecution, portfolio counseling and patent opinion work for clients in the life sciences and medical device fields.
