Markus AI: Your Trademark Intelligence Assistant

By GleanMark Research Team

5 min read

Markus is GleanMark's AI-powered trademark assistant. Ask questions in plain English and get answers backed by real USPTO data — 13M+ trademark records, TTAB proceedings, prosecution histories, and your own portfolio. Markus can search, analyze, compare, and monitor, all through conversation.

What You Can Do

  • Search trademarks — "Find marks similar to Moonlight Coffee in Class 43"
  • Compare marks — "Compare TESLA and TESLAR for confusion risk"
  • Run knockout searches — "Run a knockout search for BRIGHTPATH in Class 9"
  • Analyze prosecution history — "Show me the prosecution timeline for serial 90244982"
  • Research office actions — "What are the best arguments against a 2(d) refusal for this mark?"
  • Check upcoming deadlines — "What deadlines are coming up for my tracked marks?"
  • Investigate owners — "What has Nike filed in the last 6 months?"
  • Analyze TTAB proceedings — "Analyze TTAB proceeding 91285431"
  • Check domain availability — "Is brightpath.com available?"
  • Check brand availability — "Check brand availability for BRIGHTPATH"
  • Get Nice class recommendations — "What classes should I file a coffee shop under?"

How It Works

  1. Navigate to Markus — Click "Markus AI" in the sidebar, or go to /markus
  2. Type your question — Use natural language. Markus understands trademark terminology but you don't need to use it.
  3. Watch Markus work — As Markus processes your request, you can see its current step and a summary of the sources used after it responds.
  4. Review the response — Markus returns structured answers with links to trademark pages, owner profiles, TTAB proceedings, and other GleanMark features. Click any link to see the full detail.
  5. Follow up — Ask follow-up questions in the same conversation. Markus keeps recent conversation context, though very long conversations may trim older messages.

Key Features

Conversation History

Completed conversations are saved automatically. Access past conversations from the sidebar panel in the chat view, where you can filter by title, star favorites, rename, and delete conversations.

Source Visibility

When Markus searches the database or runs an analysis, you can see what step it's currently performing and a summary of the tools used after the response completes.

Inline Charts

Markus can generate bar charts, line charts, pie charts, and composed visualizations directly in the conversation when presenting statistical or trend data.

Smart Links

Markus formats all trademark references as clickable links — serial numbers go to trademark detail pages, owner names link to owner profiles, TTAB proceeding numbers link to proceeding pages, and Nice class numbers link to class descriptions.

Workspace Awareness

Markus knows about your clients, portfolios, tracked owners, upcoming deadlines, and recent alerts. Ask "What needs my attention?" and Markus checks across the workspace data you have access to.

Example Conversations

Quick search:

"Search for trademarks similar to Moonlight Coffee" Markus runs a phonetic + trigram search and returns the top matches with similarity scores.

Workspace overview:

"What deadlines are coming up for my tracked marks?" Markus checks your upcoming deadlines and lists them by urgency.

Confusion risk comparison:

"Compare TESLA and TESLAR for confusion risk" Markus runs a mark comparison and explains the similarity factors.

Trademark lookup:

"Look up serial number 90244982" Markus fetches the trademark, shows its status, prosecution history, and any pending actions.

Tips & Best Practices

  • Be specific about classes — "Search for APEX in Class 9" gives more relevant results than just "Search for APEX"
  • Use follow-ups — After a search, ask "Which of those are in Class 25?" or "Compare the top two"
  • Ask about your data — Markus can access your clients, tracked owners, and alerts. Try "Summarize my client Acme Corp" or "What alerts fired this week?"
  • Use proceeding numbers for TTAB — "Analyze proceeding 91285431" works better than "Find the opposition between X and Y"
  • Request analysis, not just search — "Analyze the prosecution history of serial 90244982" gives a strategic summary, not just raw events
