New Polymers and Methods Patent Application
Summary
The USPTO has published a new patent application, US20260085336A1, detailing processes for forming pyridinedicarboxylic acid derivatives and copolymers. The application, filed on September 25, 2025, outlines biocatalytic methods and potential uses for these new materials.
What changed
This document is a publication of a new patent application (US20260085336A1) by the USPTO. It describes novel processes for synthesizing pyridinedicarboxylic acid (PDCA) monomers and their ester derivatives using biocatalysis, specifically mentioning protocatechuate dioxygenase enzymes. The application also covers the formation and uses of copolymers incorporating these PDCA monomers.
As this is a patent application, it does not impose immediate regulatory obligations or compliance deadlines on regulated entities. However, it signals potential future intellectual property and market developments in the areas of specialty chemicals, polymers, and pharmaceuticals. Companies operating in these sectors should be aware of this filing for competitive intelligence and potential licensing opportunities.

Abstract
The present invention relates to processes for the formation of pyridinedicarboxylic acid (PDCA), in particular, 2,4-pyridinedicarboxylic acid (2,4-PDCA) and 2,5-pyridinedicarboxylic acid (2,5-PDCA), and mono- and diester derivatives thereof, from 3,4-dihydroxybenzoic acid, via a biocatalytic reaction using, for example, a protocatechuate dioxygenase such as protocatechuate 4,5-dioxygenase or protocatechuate 2,3-dioxygenase, and a nitrogen source. The invention also relates to copolymers that comprise the pyridinedicarboxylic acid monomers and derivatives thereof, processes for the formation of the copolymers and uses for the copolymers.
