Portfolio overview

E.i. DU PONT DE Nemours AND Company has been granted 882 US utility patents between 2015 and 2025, placing E.i. DU PONT DE Nemours AND Company at rank #511 across all assignees tracked by PlainPatent. This portfolio spans 184 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.6 claims per patent with primary concentration in C12N (MICROORGANISMS OR ENZYMES; COMPOSITIONS THEREOF; PROPAGATING, PRESERVING, OR MAINTAINING MICROORGANISMS; MUTATION OR GENETIC ENGINEERING; CULTURE MEDIA). As a US Corporation, E.i. DU PONT DE Nemours AND Company is one of the broader-portfolio assignees in the PatentsView dataset. By volume, E.i. sits between Societe Des Produits Nestle S.a. (887 patents, rank #507) and Amgen Inc. (875 patents, rank #515) - the closest US assignees by grant volume. The composite Innovation Score of 57.8/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 75 grants, compared with 807 in the 2015–2019 window, a -91% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. E.i. DU PONT DE Nemours AND Company's 13.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark E.i. DU PONT DE Nemours AND Company against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
