Advanced Manufacturing Progress: Leveraging R&D Tax Credits

February
2019
Advanced Manufacturing Progress
Rose-Marie Brandwein
Process intensification (PI) is the development of new technologies that dramatically improve manufacturing processes. It can involve innovating existing processes and/or creating totally new ones, and it increasingly leverages big data, artificial intelligence, additive manufacturing, and other advanced manufacturing concepts. Inherent to PI is the need for innovation and research and development (R&D). However, this can be extremely expensive and time-consuming. In addition, many innovations fail at or before the pilot stage and/or require numerous modifications or revisions that may produce little or no return on investment.

Patent Update
M. Henry Heines
Chemical engineers often adjust process parameters to improve the conversion, yield, or product purity of a chemical reaction. But, when is improvement to a known reaction enough to qualify for a patent? The recent decision in E. I. DuPont de Nemours & Co. and Archer Daniels Midland Co. (ADM) v. Synvina C.V. answers this question.
