GleanMark
Live USPTO trademark search, conflict screening, and TTAB and office-action research across 14M records.
Add to Claude (opens in new tab)GleanMark gives Claude live access to the U.S. trademark record: over 14 million USPTO filings, plus TTAB (Trademark Trial and Appeal Board) proceedings and Board opinions. Ask whether a name is already taken in a category, who owns a mark, how often an owner opposes other applications, why an application was refused, how many applications were filed in a year, or who the top filers are in a class. Results cite real USPTO serial and registration numbers and link back to gleanmark.com. Public research needs no account. Signed in with a GleanMark account, Claude can also run knockout searches and read the user's own portfolios, clients and deadlines, within the user's plan. Nothing is filed, edited, deleted or paid for; four research tools (prosecution history analysis, TTAB proceeding analysis, Office Action research and TTAB pleading research) save their analysis to the user's GleanMark account so it can be reopened. Every other tool only reads. Built for trademark attorneys, paralegals, brand owners and researchers.
