About Theodore
Theodore Chiacchio built his career at the meeting point of science and the law. He earned a Bachelor of Arts from Bucknell University in 1999, majoring in biology and French. He then went on to Cornell Law School, receiving his J.D. in 2002. The combination of a science undergraduate degree and a law degree shaped the practical contours of his legal work.
After law school, Chiacchio pursued work that drew on both technical training and legal training. He is admitted to practice in Illinois, New Jersey and New York. He also holds authority to appear before the U.S. District Court for the Northern District of Illinois, the Federal Circuit, and is registered with the United States Patent and Trademark Office. Those admissions allow him to handle matters at the trial, appellate and patent prosecution levels.
His practice centers on intellectual property. He advises clients on patent-related matters, prepares and prosecutes patent applications before the USPTO, and handles related disputes in federal court and on appeal. The scientific background from Bucknell gives him a working fluency with technical subject matter. That fluency informs how he evaluates inventions, drafts claims, and assesses the strengths and risks of enforcement or defense strategies.
Chiacchio maintains memberships in several state bars, including the Illinois State Bar, the State Bar of New York, and the New Jersey State Bar. Those memberships reflect the multi-jurisdictional character of his practice and permit him to collaborate with counsel and clients across different forums. He also appears in federal patent contexts, which places him regularly before administrative and appellate bodies that govern patent rights.
He practices under the name Chiacchio IP, LLC. The firm handles a mix of patent prosecution, counseling and litigation-related work for clients whose needs range from patent filing to courtroom advocacy. He brings a methodical approach to client matters, combining a comfort with technical detail and a pragmatic view of legal options.
Colleagues and clients encounter an attorney who moves easily between technical descriptions and legal argument. He structures work to address both the immediate task — for example, drafting an application or responding to an office action — and the longer-term consequences for a client’s intellectual property portfolio. He currently practices at Chiacchio IP, LLC. His practice concentrates on intellectual property matters, including patent prosecution and related litigation.
