Editorial Policy

Last updated: June 2026

This page explains who is behind PatentCliff, how our pages are produced, and the standards every page on patentcliff.org is held to. We publish it so readers, journalists, and search engines can judge our work by a clear, stated process rather than guesswork.

Who runs PatentCliff

PatentCliff is an independent publication built and maintained by the PatentCliff Team. We are not funded, owned, or directed by any of the agencies, companies, or organizations that appear in our data. We do not accept paid placements, sponsored rankings, or fees to add, alter, or remove an entry. Our editorial judgment is not for sale.

How our content is produced

PatentCliff covers U.S. patent filings, expirations, and patent cliffs. Our pages are assembled programmatically from the USPTO PatentsView API: we fetch the primary records, process them with documented, repeatable methods, and render them as pages a non-specialist can read. We pull USPTO PatentsView data for granted patents, compute expected expiration from grant date plus term-adjustment days, and flag patents expiring within the next 18 months. Citation counts and assignee rollups are derived from the PatentsView relationships.

We are transparent that this is a data-publishing operation, not a wire service of on-the-ground reporters. Where we add narrative, that narrative describes and interprets the underlying public data — it never invents facts the data does not contain. Automated assembly is reviewed against the source, and the methodology behind any score or ranking is documented and linkable.

Editorial standards

  • Primary source only. Every figure traces back to the USPTO PatentsView API, cited and linkable on the page where it appears.
  • No invented numbers. If a value is not in the underlying public data, it does not appear on patentcliff.org. We never generate synthetic statistics to fill gaps.
  • Documented methodology. Rankings, grades, and composite scores are editorial calculations derived from public data using stated, repeatable formulas — not certifications or endorsements.
  • Dated and refreshed. Refreshed monthly when USPTO posts the PatentsView update.
  • Corrections welcome. When a reader or the source identifies an error, we fix it — see our Corrections Policy.

Verification and fact-checking

Because our numbers come straight from the USPTO PatentsView API, our verification work is about faithful processing rather than re-reporting. The detail of how we check figures before publication is described in our Fact-Checking Policy.

Ownership and funding transparency

PatentCliff is part of a small portfolio of independent public-data sites. The site is free to read and carries no display advertising. We do not sell personal data. Where an outbound link is an affiliate link, it is disclosed and never changes our editorial judgment.
