Markus AI: The Trademark Copilot That Searches, Analyzes, and Drafts for You

Trademark research is not one task. It is dozens of small tasks stitched together — searching a database, pulling prosecution records, comparing similar marks, checking TTAB filings, reading office actions, and synthesizing all of it into a recommendation. Every time you switch tabs, reformat a query, or copy data between systems, you lose context and burn time.

Markus is an AI trademark copilot built to eliminate that friction. It has direct, real-time access to 13.9 million USPTO trademark records, 240 million prosecution events, and over 650,000 TTAB proceedings. You ask questions in plain English. Markus returns sourced, verifiable answers — not guesses, not hallucinations, not stale training data.

The Problem: Death by a Thousand Tabs

A simple question like "Does Acme Corp have any active TTAB proceedings?" requires a surprising number of steps when you do it manually. You search the owner on TSDR. You scroll through their marks. You cross-reference each serial number against TTAB's ESTTA system. You piece together proceeding numbers, party roles, and case status from multiple pages. Twenty minutes later, you have your answer — and you have lost the thread of whatever you were working on before.

Now multiply that by every question that comes up during clearance, prosecution, or portfolio management:

• "Are there any phonetically similar marks in Class 9?"
• "What happened in the prosecution of serial 97-654321?"
• "Who are the top filers in cosmetics this year?"
• "Which of my client's marks have upcoming deadlines?"

Each of these requires a different tool, a different interface, and a different mental model. The information exists. Getting to it is the bottleneck.

Why We Built a Specialist, Not a Chatbot

General-purpose AI tools like ChatGPT can sound authoritative about trademarks, but they generate answers from training data — data that may be months old, partially wrong, or entirely fabricated. When a general LLM tells you a mark is "likely registered," there is no way to verify that claim without doing the manual lookup yourself, which defeats the purpose.

Markus takes a fundamentally different approach. It does not generate trademark information from memory. It queries the actual USPTO database in real time using over 30 purpose-built tools. Every serial number, every owner name, every prosecution event links back to official USPTO data. When Markus says a mark is registered, it is because it just checked.

This matters because trademark work is high-stakes. A missed conflict in clearance can cost a client their brand. A wrong filing date in a TTAB brief can undermine an entire case. The margin for error is zero, and the tool you rely on needs to meet that standard.

What Markus Can Do

Markus covers four broad categories of trademark work, each backed by specialized tools that query live data.

Search and Discovery

Ask Markus to find trademarks by name, owner, or attorney — with full support for phonetic matching, fuzzy search, and Nice class filtering. Need marks that sound like "ZENITH" in Class 9? Markus runs a phonetic search across 4.5 million live marks and returns ranked results in seconds. Need an examiner-style knockout search for a new brand name? Markus executes a multi-step search combining phonetic matching, coordinated classes, and trigram similarity — the same methodology a USPTO examining attorney would use.

Portfolio Intelligence

If you manage client portfolios, Markus can pull your tracked marks, surface upcoming deadlines, summarize recent alerts, and assess portfolio risk — all in a single conversation. Ask "Which of my client's marks need attention this month?" and get a prioritized list with filing dates, maintenance windows, and status flags. No spreadsheets, no portal-hopping.

Deep Analysis

This is where Markus goes beyond search. It can run a full 13-factor DuPont likelihood-of-confusion analysis between two marks, generate a narrative prosecution history for any serial number, analyze TTAB proceedings with document review, and research office actions with cited-mark analysis and coexistence strategies. These analyses take one to two minutes because they involve multiple AI models working through the data, but they deliver the kind of structured, sourced analysis that would take a paralegal an hour or more.

Research and Recommendations

Markus can check brand availability across both the trademark register and domain registrars, recommend Nice classes for a business description, track filing trends for any owner over time, and conduct web research on companies or legal topics with grounded citations.

A Practical Example

Here is what a typical conversation flow looks like:

You: Search for NOVA in Class 9.

Markus: Found 47 live marks containing "NOVA" in Class 9. Here are the top results by relevance... [table with serial numbers, owners, status, filing dates]

You: Compare NOVA with NOVACORE for likelihood of confusion.

Markus: Quick comparison: Both marks share the dominant element "NOVA." NOVACORE adds a descriptive suffix. The marks have moderate visual and high phonetic similarity. The goods overlap in Class 9 electronics. This pairing has elevated confusion risk.

You: Run a full DuPont analysis on those two.

Markus: Starting the DuPont analysis now — this will take about a minute... [Returns a structured 13-factor analysis with similarity scoring, goods comparison, channel analysis, consumer sophistication assessment, and a cited recommendation]

Each step builds on the last. Markus retains the conversation context, so you never have to re-specify what you are working on.

The fast tools — search, lookups, data retrieval — respond in under two seconds. The AI-powered analysis tools take longer because they are doing real analytical work: reading documents, comparing legal standards, and synthesizing findings. Markus tells you when something will take a moment, so you are never left waiting without context.

Who Markus Is For

Trademark attorneys who want a research assistant that can pull case data, run comparisons, and draft analysis without the overhead of training a junior associate on every database and tool.

Paralegals and portfolio managers who spend hours each week checking deadlines, pulling prosecution records, and compiling status reports across dozens of client marks.

In-house counsel who need quick trademark intelligence — conflict checks, filing trend data, competitive analysis — without maintaining expensive subscriptions to multiple specialized platforms.

Any trademark professional who has ever thought, "I know this information exists somewhere in the USPTO data. I just need a faster way to get to it."

Markus is not a filing service. It does not submit applications or respond to office actions on your behalf. It is a research and analysis tool that makes the human work faster and better-informed. You stay in control. Markus handles the data retrieval and the first pass at analysis.

Getting Started

Markus is available on Professional ($249/seat/month) and Firm ($599/seat/month) plans. Once your account is active, you can access Markus directly at gleanmark.com/markus-ai.

No setup or configuration is required. Open the chat interface, type a question, and Markus goes to work. It remembers the context of your conversation, so you can ask follow-up questions naturally — drill into a search result, compare two marks from your earlier query, or pivot from clearance research to portfolio review without starting over.

If you want to explore how Markus fits into a broader trademark search strategy, start with a simple query — something you would normally look up manually. See how fast the answer comes back. Then try chaining a few questions together: search, compare, analyze. That is where the real time savings show up.
