PlainPatent

Highest Claim Depth Companies

Top 100 companies by average claims per patent — a proxy for patent complexity and legal strength. Min. 50 patents.

Average claims per patent is a structural proxy for invention complexity and legal defensibility. Each independent claim defines a distinct scope of protection, and more claims usually mean broader coverage that competitors must design around — increasing both prosecution cost and enforcement leverage. The 100 companies ranked below all hold at least 50 US grants between 2015 and 2025, the floor PlainPatent applies to keep small-portfolio noise out of the leaderboard.

Industry context: the median across USPTO grants in this period averages roughly 12 claims per patent, while the top of this leaderboard reaches 30–50+. High claim depth is not strictly better — pharmaceutical patents legitimately need expansive claims, while consumer-software patents are often issued with tight scopes. Read each company's score against its CPC concentration on the company profile to understand whether the depth reflects portfolio strategy or industry baseline.
