Who We Are

Abraham J. Rosner

Mr. Rosner, a member of the firm’s chemical practice group, brings 8 years of hands-on industrial experience as a semiconductor device manufacturing engineer for the IBM Corp. prior to joining Sughrue, where he also served as liason for introduction of new products. At IBM, Mr. Rosner worked with photolithography and hot process operations such as RIE, photoresist exposure and development, epitaxy, ion implantation and CVD, as well as the tooling for carrying out those unit operations, giving him a unique perspective as to how advances in the art are achieved on a day to day basis. He also evaluated invention disclosures for their potential commercial and practical value, which evaluation was used to decide those inventions for which protection would be sought. 

Mr. Rosner was resident at the firm’s Tokyo office for a four year assignment, where he actively counseled clients on matters relating to validity and infringement. While at the Tokyo office, Mr. Rosner was a frequent lecturer at various trade associations and Japanese patent attorney groups on topics relating to changes in the U.S. patent and case law and strategies for implementing those changes to advantage. While resident in Tokyo, Mr. Rosner was also a foreign attorney member of the Tokyo Dai-Ni-Bar. 

Mr. Rosner’s practice focuses on patent prosecution, reexamination, appeals and opinions relating to validity and infringement, as well as licensing. In addition to his industrial experience, Mr. Rosner has a Masters degree in chemical engineering from the University of Maryland and a Professional Engineering (PE) license in the state of Virginia. This gives Mr. Rosner an ideal vantage to cover a broad range of technologies, such as semiconductor devices, LEDs, electrodes, secondary batteries, equipment used for semiconductor manufacturing, packaging materials, machine tools, electrolytic apparatus, pharmaceuticals, imaging materials, tones, inks, biofuels, automotive gas sensors, sensor control apparatus, spark plugs, ignition controls, multilayer ceramic circuit boards, alloys, cutting tools, freon substitutes, stain repellants, fluorinated protective coatings, polymers, fluororubbers, elastomers, and drug delivery systems.
