FAQ

Get answers to common questions about Lessie AI.

What is an AI patent attorney finder?

An AI patent attorney finder is a tool that searches the open web in plain English to surface patent attorneys matching your criteria, then returns verified contact data. Lessie AI ranks results by relevance and fit instead of keyword filters, so a single query like a real description of who you need typically returns 50–200 qualified patent attorneys in under a minute.

How does Lessie AI find patent attorneys?

Lessie AI parses your natural-language brief, runs parallel searches across USPTO Patent Bar and dozens of other sources, then scores each patent attorney on signals like recency, topical fit, and audience overlap. The pipeline enriches each match with a verified email and a one-line context snippet, so you can review and reach out without manual research.

Where do the patent attorneys in the results come from?

Results are aggregated from USPTO Patent Bar, Martindale-Hubbell, LinkedIn, law firm directories, patent filings. Lessie AI re-crawls high-signal sources weekly and validates every email through SMTP and MX checks before showing it. You see the source URL next to each patent attorney, so you can click through and verify context yourself before sending outreach.

How is this different from Martindale-Hubbell?

Martindale-Hubbell is a curated database with fixed filters; Lessie AI is an open-web search engine driven by natural language. That means you can describe a niche patent attorney profile in one sentence and get fresh results pulled live, including people who never opted into a directory. You also get verified emails inline, not just profile links.

How is this different from USPTO Patent Bar?

USPTO Patent Bar relies on its own data warehouse refreshed on a fixed schedule, while Lessie AI searches the live web on every query and re-verifies emails on demand. That keeps results current and lets you find patent attorneys who appeared in news, podcasts, or GitHub last week. Pricing also scales by results delivered, not seat count.

Can I find patent attorneys for a niche tech area or jurisdiction?

Yes — niche briefs are where Lessie AI outperforms keyword tools. Specify the tech area or jurisdiction, geography, and any disqualifiers in plain English, and the engine runs targeted sub-searches across specialty sources. Most niche queries return 30–100 high-fit patent attorneys, and you can refine the brief inline if the first batch is off.

How accurate are the patent attorney email addresses?

Email accuracy averages 92–96% across patent attorney searches because Lessie AI runs catch-all detection, MX lookup, and SMTP handshake on every address before delivery. Invalid or risky emails are flagged so you do not waste sends. You only pay for verified contacts, and bounced emails are credited back automatically.

How much does it cost to find patent attorneys?

Lessie AI uses credit-based pricing — roughly one credit per verified patent attorney contact — with free credits to test the engine on your real brief before you commit. Most teams run 500–5,000 searches per month, and unused credits roll over. There are no seat fees or annual contracts, so you can scale up only when results land.
