Markus is GleanMark’s AI-powered trademark assistant. Ask questions in plain English and get answers backed by real USPTO data — 14M+ trademark records, TTAB proceedings, prosecution histories, and your own portfolio. Markus can search, analyze, compare, and monitor, all through conversation.

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. A dedicated conversation history page is also available for browsing and managing all past conversations.

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. Responses also include a Sources button showing the count of supporting sources cited in the answer — click it to view the underlying records.

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

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.

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.

Upload images and documents directly into the chat — drag and drop, paste from clipboard, or use the paperclip icon. Markus reads the file contents and incorporates them into its analysis.

Create a read-only link to any conversation and share it with colleagues or clients. The shared view displays the full conversation without edit access. Available on Starter and above.

Long-running tasks — such as drafting an office action response or analyzing a TTAB proceeding — run in the background. Markus shows a live status card in the conversation, and the result appears when the work completes. Background jobs persist across page reloads, so you can navigate away and return to find the finished result.

While Markus is generating a response, you can type your next question and it will queue automatically. The composer stays active during streaming, so you can keep drafting without waiting.

Rate any response as helpful or not helpful. If you mark a response as not helpful, you can select a reason to help our team improve Markus.

Ask Markus to rephrase any answer without running new research. Choose from three options: make the answer clearer, shorter, or client-ready.

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.
