Who it's for

Same engine.
Different job.

A broker valuing a portfolio and an inventor asking whether anyone copied them need the same underlying answer — who is practising this patent, and can you prove it. What differs is what you do next. Pick the one that matches your work.

✓ The same bar, whoever you are

Every result is checked against real, citable evidence before it reaches you, and anything that can't be evidenced is dropped rather than shown with a caveat. See every source we search →

Not sure which fits? Bring a patent you already know inside out — the fastest way to judge the output is to read it about an invention you could argue yourself.
