Trademark search and watch in the US

Trademarks in the US are registered with the United States Patent and Trademark Office (USPTO). Opposition period for newly published applications: 30 days; up to 180 with extensions. Ulawk searches its trademarks and patents by owner, number or mark name and compares each new application with the marks you watch, showing the last day to oppose.

Opposition deadline in the US.

  1. Search before you file

    Check United States Patent and Trademark Office (USPTO) records for the same or a similar mark and for the marks of a counterparty.

  2. Add the marks you watch

    Enter each word mark with its Nice classes; related classes are compared too.

  3. Review each finding

    New applications similar to your marks are listed with a risk level: high, medium, low.

  4. Act before the deadline

    Each finding shows the last day to oppose, counted from the publication date.

  5. Share the list

    Export findings to Excel for your attorney or client.

Limits

What is not included.

Said plainly.

Base deadline only

The last day shown is the base period; extensions you obtain are not added.

Classes, not goods

For US applications the comparison uses classes; the goods and services text is not read.

Not legal advice

Findings support your attorney; whether to oppose is a legal decision.
