How to Read a TSDR Record: A Practical Guide for Trademark Attorneys

The Trademark Status and Document Retrieval system, universally known as TSDR, is the authoritative record of every trademark application and registration filed with the USPTO. It contains the prosecution history, current status, ownership information, filing basis, and every document associated with the mark. For trademark attorneys, TSDR is not just a reference tool. It is the single source of truth for deadline calculation, status verification, and portfolio management.

Despite its importance, many attorneys use TSDR only superficially, checking the current status and moving on. This article is a practical guide to reading a TSDR record thoroughly: what each field means, how the prosecution history timeline works, what the status codes actually indicate, and how to use TSDR data for accurate deadline calculation.

Accessing TSDR

TSDR is available at https://tsdr.uspto.gov. You can search by serial number, registration number, or reference number. The system returns a summary page with tabs including Status, Documents, and Maintenance.

There are two important access methods beyond the web interface:

• Direct URL access: You can also link directly to specific TSDR records and documents, but the exact URL format is controlled by the current TSDR interface. This is useful for bookmarking specific marks or sharing links with clients.
• Programmatic access: Automated systems can retrieve structured trademark data programmatically through USPTO data services and APIs, which is how docketing software monitors prosecution histories without manual entry.

The web interface is adequate for checking individual marks. For portfolio management across dozens or hundreds of marks, the API is essential because it allows systematic monitoring without manual lookups for each mark.

Key Fields on the TSDR Summary

The TSDR summary page presents the most important information about a trademark record. Here is what each field means and why it matters for docketing:

Serial Number and Registration Number

The serial number is assigned when the application is filed and remains constant throughout the life of the mark. It is the primary identifier during prosecution. The registration number is assigned when the mark is registered and is used for all post-registration filings. A mark that has not yet registered will have a serial number but no registration number.

For docketing purposes, you need both numbers. Serial numbers are used to track prosecution deadlines (office actions, SOU filings). Registration numbers are used to track maintenance deadlines (Section 8, Section 9, Section 71). When importing a mark into a docketing system, the serial number is typically the starting point because it provides access to the complete prosecution history.

Filing Basis

The filing basis determines the procedural path the application follows and affects which deadlines apply:

• Section 1(a) — Use in commerce: The mark was already in use at the time of filing. No Statement of Use is required. The application proceeds directly to examination, publication, and registration (assuming no opposition).
• Section 1(b) — Intent to use: The applicant intends to use the mark but has not yet used it in commerce. After the application is approved and published without opposition, the USPTO issues a Notice of Allowance. The applicant then has 6 months to file a Statement of Use (with up to five additional 6-month extensions available, allowing a maximum of 36 months after the Notice of Allowance). This basis generates the most complex deadline chains.
• Section 44(e) — Foreign registration: Based on a registration in the applicant's country of origin. This basis has its own procedural requirements and should be reviewed carefully when determining prosecution strategy and post-registration obligations.
• Section 66(a) — Madrid Protocol: The application is based on an international registration through WIPO. These marks follow different maintenance rules post-registration, requiring Section 71 declarations instead of Section 8 declarations. The renewal is handled through WIPO rather than the USPTO.

The filing basis is one of the first things to check when importing a mark into a docketing system, because it determines which deadline rules apply for the entire lifecycle of the mark.

Current Status and Status Date

The current status field shows where the mark stands in the prosecution or registration lifecycle. The status date indicates when the status last changed. Together, these two fields tell you what has happened most recently and how long ago it happened.

Status alone is not sufficient for deadline calculation. Two marks can both show a status of "Registered" but have very different deadline profiles based on when they were registered. The status date, combined with the registration date, is what determines when maintenance windows open and close.

Prosecution History (Document Tab)

The Documents tab contains the complete prosecution history: every filing, every office action, every response, every status change. Events are listed chronologically with the most recent event at the top. Each entry includes a date, a description code, and (for most events) a link to the associated document.

This is the most valuable section of the TSDR record for docketing purposes. The prosecution history tells you not just what the current status is, but how the mark got there, and what deadlines have already been triggered and resolved along the way.

Reading the Event Timeline

The prosecution history in TSDR is a chronological list of events, each with a date and a description. Reading this timeline correctly is essential for understanding what deadlines exist and whether they have been met.

Here is a typical prosecution timeline for a Section 1(b) application that reaches registration:

1. NEW APPLICATION — RECORD INITIALIZED: The application was filed. The serial number is assigned.
2. ASSIGNED TO EXAMINER: An examining attorney has been assigned. Examination typically takes 3 to 8 months from filing.
3. NON-FINAL OFFICE ACTION MAILED: The examining attorney found issues. The applicant has 3 months to respond (extendable to 6 months).
4. TEAS RESPONSE TO OFFICE ACTION RECEIVED: The applicant filed a response. This event confirms the deadline was met.
5. APPROVED FOR PUBLICATION: The examiner accepted the response. The mark will be published in the Official Gazette.
6. PUBLISHED FOR OPPOSITION: The mark appeared in the Official Gazette. Third parties have 30 days to file an opposition or request an extension of time to oppose.
7. NOA MAILED — SOU REQUIRED: No opposition was filed. The Notice of Allowance was issued. The applicant has 6 months to file a Statement of Use.
8. TEAS STATEMENT OF USE RECEIVED: The SOU was filed.
9. REGISTERED: The SOU was accepted and the mark is now registered. The registration number is assigned. Maintenance deadlines (Section 8/9) now apply.

Each event in this timeline either creates a deadline, resolves a deadline, or modifies an existing deadline. An automated docketing system reads this timeline event by event and generates the correct deadlines based on what actually happened, rather than requiring the attorney to calculate deadlines manually from status alone.

Understanding Status Codes

TSDR uses a set of status codes that describe the current state of the application or registration. These codes are more granular than the simple categories most attorneys use day to day. Here are the most important ones and what they mean for docketing:

Pre-Registration Status Codes

• New Application (600 series): The application has been filed but not yet assigned to an examiner or fully processed. No action is required from the applicant at this stage.
• Non-final and final office action statuses: An office action has been issued. This is the most time-sensitive pre-registration status because it triggers a 3-month response deadline. The distinction between non-final and final determines the available response options.
• Approved for Publication (900 series): Examination is complete and the mark has been approved. The mark will be published in the Official Gazette. No action is required from the applicant.
• Published for Opposition: The mark is in the 30-day opposition window. No action is required unless an opposition is filed.
• Notice of Allowance Issued: For 1(b) applications, this triggers the SOU deadline chain. The applicant has 6 months to file the SOU or the first extension request.

Post-Registration Status Codes

• Registered (800 series): The mark is registered and in force. Maintenance deadlines are now calculated from the registration date. The first Section 8 window opens at year 5.
• Section 8 — Accepted: The declaration of continued use was accepted. The next maintenance deadline is the combined Section 8 & 9 at the 10-year mark.
• Section 8 & 9 — Accepted: The combined renewal was accepted. The registration is renewed for another 10 years. The next Section 8 & 9 is due at the next 10-year anniversary.
• Cancelled/Expired: The registration is no longer in force, either because a maintenance filing was missed (Section 8 not filed) or because the registration was not renewed (Section 9 not filed). Once cancelled or expired, the registration cannot be restored.

Status Code Gotchas

Several status codes are commonly misread or misunderstood:

• "Registered — Section 8 Accepted" vs. "Registered": Both indicate an active registration, but the former tells you that the first maintenance filing has already been completed. This affects which deadlines you need to docket. If Section 8 has been accepted, the next deadline is the combined Section 8 & 9 at year 10, not a standalone Section 8 at year 6.
• Suspended status: A suspended application is not dead. It is paused, usually pending the outcome of another proceeding (such as a related application or an opposition). When the suspension is lifted, prosecution resumes and any new deadlines will be set based on the next USPTO action. During suspension, response deadlines are typically paused because no office action requiring a response is pending.
• "Dead" marks: A mark with a "dead" status in TSDR is an application that was abandoned or a registration that was cancelled or expired. It is no longer active and generates no deadlines. However, verifying that a dead mark is truly dead (and not subject to a pending petition to revive) requires checking the prosecution history for recent events.

Using TSDR Data for Deadline Calculation

TSDR provides all the raw data needed to calculate every trademark deadline. The calculation process follows a logical sequence:

1. Identify the filing basis: This determines which deadline rules apply (e.g., 1(b) applications have SOU deadlines that 1(a) applications do not).
2. Read the prosecution history: Walk through the events chronologically to identify which deadlines have been triggered and which have been resolved.
3. Check the current status: Confirm the mark's current position in the lifecycle. A mark that shows "Registered" with a registration date 4.5 years ago is approaching its Section 8 window.
4. Calculate open deadlines: Based on the events and status, determine which deadlines are currently open (response due) or approaching (filing window opening soon).

This calculation is straightforward for a single mark. For a portfolio of 50 or 100 marks, performing it manually for each mark on a regular basis is not practical. This is where automated docketing becomes essential: the system reads the TSDR data for every mark in the portfolio, performs the calculation, and surfaces only the deadlines that require attention.

DeadlineDocket pulls TSDR data automatically when you import a mark by serial number. The system reads the complete prosecution history, identifies the filing basis, calculates all applicable deadlines, and auto-completes deadlines that have already been met based on the event history. When the prosecution history changes (a new office action, a response filed, a status change), the system detects the change and updates the docket accordingly.

What TSDR Does Not Tell You

While TSDR is comprehensive, there are a few things it does not provide that matter for docketing:

• Internal client deadlines: TSDR tracks USPTO deadlines but not your firm's internal deadlines for client review, approval, or preparation. You still need a system that layers internal milestones on top of the USPTO deadlines.
• Real-time updates: TSDR is not updated in real time. There is typically a delay of one to several days between a filing or action and its appearance in the TSDR record. Do not rely on TSDR to confirm that today's filing was received today.
• Non-USPTO deadlines: For Madrid Protocol marks, WIPO deadlines (international renewal, designation changes) are not reflected in TSDR. Only the USPTO-related events (Section 71, examination) appear.
• Upcoming deadlines: TSDR shows what has happened, not what needs to happen next. It records events but does not calculate that a Section 8 window opens in 6 months or that an office action response is due in 47 days. Deadline calculation requires interpreting the events, which is what docketing software does.

Understanding these limitations is important for building a complete docketing workflow. TSDR is the foundation, the authoritative record of what has happened. Your docketing system builds on that foundation to determine what needs to happen next and when.
