PatentBrief

Methodology

How we explain patents.

PatentBrief turns granted US patents into plain English. Here is exactly how we do it, where our facts come from, and what this is — and isn’t.

Our principles

01

Plain English, from the source

Every breakdown starts from the patent itself — its claims and its specification. We translate that language into plain English rather than paraphrasing someone else's summary.

02

Facts from public records

Patent numbers, filing and grant dates, owners, status, and citation counts come from public patent data — not from estimates. Where a value isn't on the record, we leave it out rather than guess.

03

Always linked to the original

Every patent page links to the full, official document so you can read the primary source and verify anything we say.

04

What it does — and does not — cover

We pay special attention to the boundary of each patent: what the claims actually protect, and what they leave open. That boundary is the most useful and most misunderstood part of a patent.

05

Educational, not legal advice

PatentBrief is an educational resource. Our explanations are interpretations to help you understand a patent — they are not legal opinions, and they are not a substitute for a qualified patent attorney.

06

We correct mistakes

If something here is wrong, tell us and we will fix it. Accuracy matters more than being first.
