Supplemental Register vs Principal Register: Which Is Right for Your Mark?
The USPTO maintains two trademark registers: the Principal Register and the Supplemental Register. Most applicants aim for the Principal Register — and they should. But if your mark faces a descriptiveness refusal, the Supplemental Register offers a valuable alternative that many applicants overlook.
Two Registers at the USPTO
The Principal Register
The Principal Register is the default and preferred register. Marks on the Principal Register receive the full bundle of trademark rights:
- Nationwide constructive notice
- Presumption of validity
- Right to use ® symbol
- Path to incontestability (after 5 years)
- Federal court jurisdiction with enhanced remedies
- Customs recording to block imports
The Supplemental Register
The Supplemental Register was created for marks that are capable of distinguishing goods/services but do not yet qualify for the Principal Register — typically because they are descriptive. It provides limited but meaningful protection.
*Citation: 15 U.S.C. § 1091 — Supplemental Register*
Side-by-Side Comparison
| Feature | Principal Register | Supplemental Register |
|---|---|---|
| Presumption of validity | Yes | No |
| Constructive notice | Yes | No |
| Incontestability (after 5 years) | Yes | No |
| Customs recording (CBP) | Yes | No |
| Right to use ® symbol | Yes | Yes |
| Cited as barrier to similar marks | Strong | Limited (cited in examination) |
| Amazon Brand Registry | Eligible | Eligible |
| UDRP domain disputes | Strong evidence | Usable but weaker |
| Federal court access | Full | Limited |
| Published for opposition | Yes | No |
| Searchable in USPTO database | Yes | Yes |
| Registration certificate | Yes | Yes |
| Cost | Same filing fees | Same filing fees |
When the Supplemental Register Makes Sense
The Supplemental Register is an excellent strategic option in several scenarios:
1. Your Mark Is Descriptive (But Not Generic)
If your mark merely describes your goods or services and you don't have enough evidence of acquired distinctiveness for Section 2(f), the Supplemental Register preserves your rights while you build brand recognition.
2. You Need the ® Symbol Now
Both registers allow use of the ® symbol. For businesses that need to show registered trademark status — for contracts, marketing, or competitive positioning — the Supplemental Register delivers this immediately.
3. You Want to Block Similar Applications
Marks on the Supplemental Register appear in USPTO search results and will be cited against later applicants seeking to register similar marks. This provides a blocking function even without Principal Register status.
4. Amazon Brand Registry Access
Amazon accepts registrations from both the Principal and Supplemental Registers for Brand Registry enrollment. If Amazon is a key sales channel, Supplemental Register registration gets you enrolled.
5. You're Building Toward Principal Register
The Supplemental Register serves as a stepping stone. After years of use, you accumulate the evidence needed to reapply for the Principal Register.
Pro Tip: Supplemental Register registration is always better than no registration at all. You get the ® symbol, blocking power against later applicants, Amazon Brand Registry access, and a documented start date for building acquired distinctiveness.
The Path from Supplemental to Principal
After building sufficient use history, you can seek registration on the Principal Register:
Step 1: Use the Mark Continuously
Continue using the mark in commerce. Document everything — sales, advertising, customer recognition, media mentions.
Step 2: Accumulate Evidence (Typically 5+ Years)
Section 2(f) allows registration of descriptive marks that have acquired distinctiveness through extensive use. The USPTO considers:
- Length of use (5+ years creates a presumption)
- Advertising expenditures and reach
- Sales volume and geographic scope
- Consumer surveys or declarations
- Unsolicited media coverage
Step 3: File a New Application
Apply for the Principal Register with your Section 2(f) evidence. Your Supplemental Register registration supports your claim by documenting your use history.
Step 4: Reference Your History
Point to your Supplemental Register registration as evidence of continuous use. The examining attorney can see your documented track record.
When to Stay on the Principal Register
Not every mark belongs on the Supplemental Register. If your mark is:
- Suggestive — Registrable on the Principal Register without proof of distinctiveness
- Arbitrary — A common word used in an unrelated context (e.g., APPLE for computers)
- Fanciful — An invented word (e.g., XEROX)
...then always file for the Principal Register. These marks are inherently distinctive and should never be on the Supplemental Register.
Strategic Considerations
Try Principal First
The filing fees are identical for both registers. Always attempt the Principal Register first. If the examining attorney issues a 2(e)(1) refusal for descriptiveness, you can amend your application to the Supplemental Register rather than abandoning it entirely.
Amendment vs. New Application
If you receive a descriptiveness refusal, amending to the Supplemental Register is faster and cheaper than starting over. The amendment preserves your original filing date and all prosecution history.
Cost-Benefit Analysis
| Path | Time | Cost | Result |
|---|---|---|---|
| Abandon application | Immediate | Lost filing fees | No protection |
| Argue suggestiveness | 2–6 months | Attorney fees for response | Principal Register (if successful) |
| Submit 2(f) evidence | 2–6 months | Attorney fees + evidence | Principal Register (if evidence sufficient) |
| Amend to Supplemental | 1–2 months | Minimal additional cost | Supplemental Register (immediate) |
Marks That Cannot Be on Either Register
Some marks cannot be registered on any register:
- Generic terms — "COMPUTER" for computers
- Functional features — Product shapes that serve a utilitarian purpose
- Deceptive marks — Marks that deceive consumers about the nature of the goods
- Immoral or scandalous marks — Though this ground has been narrowed by recent Supreme Court decisions
