Joseph C. Suhadolnik is an experienced patent practitioner and former senior research chemist with a strong background in organic and polymer chemistry, photo chemistry, dyes/pigments, industrial coatings, UV absorbers, energy storage devices, electronic displays, and image preservation. Joe has 10 years of experience as an in-house patent agent at Ciba Specialty Chemicals, BASF, and Chemtura Corporation. He has over 15 years of experience in industrial research and is an inventor on more than 65 issued US patents. As a researcher and patent agent, Joe has worked closely with technology and business directors, academic consultants, chemists involved in basic research, product discovery, testing, product development, and scale-up of plant processes, making him effective in communicating across all functions of an organization involved with innovation and maintenance of an IP portfolio. In recent years, Joe has expanded his practice to include new fields and a variety of mechanical cases. He has drafted and prosecuted patent applications in the US, managed patent prosecution in countries outside the US, and provides his insights on a variety of IP issues.

Accomplishments

  • Successfully prosecuted more than 250 US patent applications, and prepared more than 100 new patent applications
  • As in-house agent, managed world-wide patent portfolio for international specialty chemical company with business in both industrial and consumer products
  • Developed and presented materials to educate inventors on patentability issues, understanding patent language, claim construction and validity,
  • Analyzed literature, patent landscapes and individual patent portfolios used in determining freedom-to-operate for new product introduction, evaluation of research proposals, and possible business acquisition
  • Provided technical support and patent analysis for asserting patent claims against infringers, refuting infringement claims from outside parties, and in negotiation of favorable settlements
  • As a research chemist was active in the invention, development and introduction of commercial products sold for stabilization of industrial and automotive coatings, thermoplastics, personal care and household formulations
  • Developed patent strategies for antioxidant, flame retardant, energy storage, image protection and consumer care product lines
  • Developed highly stable UV absorbers for automotive coatings and light stabilizers for colored candle wax that have become standards in their respective industries
