Frequently Asked Questions
What does a Full Clearance Search include?
The Full Clearance Search includes (1) erwin AI search across the USPTO federal database with phonetic and similarity analysis, domain availability check across .com/.net/.org/.io and more, and common law web presence analysis; (2) a Lynch LLP attorney review of all findings; and (3) a formal written clearance opinion letter delivered as a PDF.
How is this different from the free trademark search?
The free trademark search gives you a quick pass/fail against USPTO records. The Full Clearance Search goes deeper — broader federal analysis, domain checking, common law uses — and adds a written attorney opinion letter you can rely on when making business decisions.
How long does it take?
The AI search typically completes within minutes of payment. The attorney opinion letter is delivered within 3–5 business days.
What does the opinion letter look like?
The opinion letter is a formal PDF document on Lynch LLP letterhead summarizing all search findings, the attorney's risk assessment (Low/Moderate/High/Very High), and a recommendation to Proceed, Proceed with Caution, or Do Not Proceed.
Does this include USPTO filing fees?
No. The $450 covers the clearance search and attorney opinion only. USPTO filing fees ($350/class) apply separately if you decide to file.
Do I need an attorney engagement letter?
