Applying for a U.S. trademark is no simple task, requiring a series of procedures and preparations. Among these, proof of use is a critical step in the application process, significantly impacting both trademark registration and subsequent usage. Without proof of use, securing a U.S. trademark registration is virtually impossible. Let's delve into what constitutes proof of use.

 I. What is Evidence of Use?

Evidence of use refers to proof that the applicant has actually used the trademark in commercial activities. This evidence may include sales records, advertising materials, product packaging, and similar documentation. Its purpose is to demonstrate that the trademark has gained market recognition and established a certain level of prominence, thereby providing strong support for trademark registration.

 II. Timelines for Submitting Evidence of Use for U.S. Trademarks

1. Application Stage

-   Registration Based on Actual Use: Evidence of use must be submitted at the time of registration.

-   Registration Based on Intended Use: Evidence of use must be submitted within 6 months of receiving the Notice of Allowance. This period may be extended, with each extension granting an additional 6 months. Extensions are limited to a maximum of 5 times, but the total extension period cannot exceed 36 months from the date the Notice of Allowance was issued.

2. Registered Phase

For registered U.S. trademarks, the owner must submit a declaration of use and supporting evidence between the 5th and 6th year following registration to maintain validity. If missed, submission is permitted within a 6-month grace period following the deadline, subject to payment of a grace period surcharge.

3. Renewal Phase

U.S. trademarks are generally valid for 10 years. During the 9th to 10th year after registration, and for every subsequent 10-year renewal, the trademark owner must submit a declaration of use and evidence of use. Similarly, if the deadline is missed, submission is permitted within a 6-month grace period following expiration, subject to payment of an additional fee.

 III. General Requirements for Evidence of Use of U.S. Trademarks

1. Actual Use

Samples must authentically reflect the trademark's actual use in the sale or advertising of goods or services. Simulated samples or prototypes are strictly prohibited. Applicants must ensure provided samples clearly demonstrate the trademark's practical application in commercial activities, enabling examiners to visually assess actual usage.

2. Direct Association

A clear and direct connection must exist between the trademark and the goods or services listed in the application. Samples should clearly indicate the association between the trademark and the designated goods or services, enabling consumers to identify the source of the corresponding goods or services through the trademark. For example, for goods trademarks, samples should demonstrate the direct connection between the trademark and the goods themselves; for service trademarks, samples should reflect the close association between the trademark and the services provided.

3. Consistency

The trademark on the sample must be identical to the mark applied for or registered, with no significant alterations. Elements such as font, graphics, and colors should precisely match the description in the application documents to ensure the trademark's distinctiveness and consistency. Any unauthorized modifications may result in application rejection or registration revocation.

IV. U.S. Patent and Trademark Office Requirements for Evidence of Use of Trademarks (Classes 1-34)

1. Acceptable Types of Samples

Labels: Labels affixed to or photographs of products displaying the trademark. The label must clearly show the trademark and be closely connected to the goods, enabling consumers to identify the source of the goods through the label.

Packaging: Images of the trademark on product packaging. The trademark on the packaging must be prominent and easily recognizable, clearly indicating the source of the goods.

Product Display: Images of merchandise displayed for sale in a store, showing the trademark. The image must clearly display the goods and their trademark, allowing consumers to visually see the trademark's actual application in the sale of the goods.

Webpage: Screenshots of webpages selling the goods, where the mark is displayed near the product, including pricing and purchase options (e.g., “Add to Cart” button). The webpage screenshot must include the full URL and date of access to prove the trademark's use in online sales.

2. Sample Presentation Requirements

These samples must directly display the mark in connection with the goods and present it in a manner recognizable to consumers as indicating the source of the goods. The trademark should be prominent and easily identifiable, without being obscured or blurred by other elements. Additionally, the samples should clearly demonstrate the association between the trademark and the goods, enabling examiners to confirm the actual use of the trademark.

 V. Requirements for Evidence of Use of U.S. Trademarks for Services (Classes 35-45)

1. Acceptable Sample Types

Advertising Materials: Brochures, flyers, or advertisements displaying signs related to the services provided. Advertising materials must clearly display the trademark and detail the services offered, enabling consumers to identify the source of services through the advertisement.

Business Materials: Photographs of signs, business cards, or letterhead displaying the trademark and indicating the services provided. Business materials should prominently feature the trademark and clearly list the services offered, enabling consumers to understand the service content.

Website Pages: Screenshots of web pages displaying the services, showing the mark and describing the services provided. Screenshots should include the complete URL and date of access to demonstrate the trademark's use in online services.

2. Sample Presentation Requirements

These samples must clearly associate the trademark with the services and demonstrate consumer recognition of the trademark when these services are provided. The trademark must be prominent and easily identifiable, without being obscured or blurred by other elements. Samples should also clearly show the connection between the trademark and the services, enabling examiners to verify actual trademark usage.

VI. Important Notes

1. Authenticity of Samples

Applicants must ensure submitted samples are authentic and accurate, without forgery or alteration. Any false samples may result in application rejection or registration revocation, and may incur legal liability.

2. Sample Clarity

Samples should be clear and complete, clearly demonstrating the trademark's association with the goods or services. Images and webpage screenshots must have sufficient resolution to ensure the trademark and related elements are clearly identifiable.

3. Timeliness of Samples

Applicants should submit evidence of use promptly to ensure samples reflect recent usage. For samples like webpage screenshots, indicate the access date to demonstrate continuous trademark use.

4. Diversity of Samples

Applicants are advised to submit multiple sample types to comprehensively demonstrate trademark usage across various commercial activities. This enhances the application's persuasiveness and improves its success rate.
