Verifying against the live site and live WHOIS/DNS…
Common questions
Is espacenet.com legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns espacenet.com?
Nobody has completed AboutUs's owner verification for espacenet.com. That's true of most sites here — it isn't itself a warning sign.

Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 66 days ago); 3/3 transport and email checks available (oldest recorded about 66 days ago). This is evidence coverage, not a probability that a website is safe.
