Independent review. IonBin has no partnership with Trademark Engine and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Online US trademark filing and monitoring. Packages run $49, $299 and $539 plus USPTO and service fees; a partner API is documented. Not legal advice: search the USPTO database yourself and consider an attorney for clearance.
IonBin provides general information and software comparisons, not tax, legal, accounting or financial advice. Tax and legal rules vary by situation and jurisdiction; consult a qualified professional (CPA, enrolled agent or attorney) before acting.
AI tools can make mistakes. Verify every figure against the original documents and official IRS or state guidance before filing or signing.
Redact Social Security numbers, account numbers and EINs before uploading documents to any AI assistant, and check its data-retention settings. Upload originals only to the filing or signing software.
Requirements vary by state. File through official sources such as the USPTO trademark search and your state’s Secretary of State site.
To verify Drawn from our draft verdict; sourced use cases to come.
Trademark Engine lists Basic at $49, Standard at $299 (dedicated attorney, 15-minute consultation) and Premium at $539 (one-hour consultation, next-day processing). Each adds USPTO fees of $350 per class, or $550 if the description doesn't fit the ID Manual, plus $100 for services. Checked 2026-10-17. source ↗
