Company patents

Sonoco Development, Inc.

Sonoco Development Inc's patent strategy, while heavily focused on its core "Containers & Packaging" (70.1% of portfolio), shows a surprising shift away from manufacturing-related innovation, with "Plastics Shaping & Molding" and "Packaging Machines" experiencing significant declines of -53.3% and -57.1% respectively in 2025, and all top categories showing substantial drops so far in 2026, indicating a potential re-evaluation of its R&D priorities or a slowdown in patenting activity across its primary areas.
