Frequently Asked Questions

DuPont holds 50 US patents with an average of 31 claims per patent. The portfolio has a Patent Strength Score of 42/100 (Grade D).

DuPont has 3 patents expiring within 2 years and 7 patents expiring within 5 years. These expirations may create opportunities for competitors and generic entrants.

DuPont's key technology focus areas include Telecommunications, Computing & Data Processing. The portfolio spans 2 distinct technology classifications (CPC codes).

The Patent Strength Score (0-100, A-F) benchmarks a company's patent portfolio quality based on portfolio size (30%), claims breadth (25%), time remaining to expiration (25%), and portfolio diversity across technology areas (20%).

Last updated:

Patent Strength Score is based on portfolio size, claims breadth, time to expiration, and technology diversity using CPC classifications.

The this entity record above pulls directly from the FDA Orange Book and USPTO patent records. What follows is the per-entity context — how this entity sits in the broader U.S. pharmaceutical patent expirations distribution and which underlying factors drive the headline numbers.

Every number on this page links back to the FDA Orange Book and USPTO patent records; the methodology page describes the inputs, refresh cadence, and known limitations of the underlying data product.

For readers using this page as a decision input, the related-entity pages elsewhere on the site provide the comparison set. The most useful comparison for this entity is typically a peer within U.S. brand-name drugs with similar size, similar exposure, or similar geography — not the national-level summary alone.
