Anthony A. Hartmann

Of Counsel

Anthony Hartmann focuses his practice on post-grant proceedings before the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office (USPTO) and complex patent litigation matters in U.S. federal district courts and the U.S. International Trade Commission (ITC), representing domestic and international clients. As a registered patent attorney and litigator, Mr. Hartmann works with his clients to develop coordinated strategies aligned with their business goals.

Mr. Hartmann is experienced in managing patent portfolios and arguing before the appeals section of the PTAB. He provides clearance, infringement, and validity opinions, as well as conducts due diligence investigations and portfolio reviews.

Specific technologies at issue in Mr. Hartmann's representations have included polymers (PE, PP, PET, and polyimides); lithium and alkaline batteries; grain-oriented electrical steel; jet engines; tires; fuel cells; biofuels; optical/electrical cables; lubricants; cosmetics; pharmaceuticals and other small molecules (including metallocene catalysts); vinyl flooring; medical devices; and battery chargers. Prior to joining Finnegan, he worked as a process development engineer with the Eastman Kodak Co., focused on the scale-up of photographic film manufacturing processes from lab to pilot plant to manufacturing.

Mr. Hartmann devotes time to pro bono matters. He has represented several veterans before the U.S. Court of Appeals for Veterans Claims and represented prisoners before the U.S. Court of Appeals for the 7th Circuit and the U.S. Supreme Court.
