What is a Proof of Use file?

If the Trademark Holder of the registered trademark opts for sunrise services, the proof of use submitted by the Trademark Holder or Trademark Agent will be verified. When examining the sample of proof of use submitted by the Trademark Holder or Trademark Agent, it will be verified that the sample submitted is a sample that evidences an effort on behalf of the trademark holder to communicate to a consumer so that the consumer can distinguish the product or services of one from those of another.

Accordingly, examples of acceptable evidence would include items from either of the following categories:
1. Labels, tags, or containers from a product.
2. Advertising and marketing materials (including brochures, pamphlets, catalogues, product manuals, displays or signage, press releases, screen shots, or social media marketing materials).

An uploaded and verified Proof Of Use file is valid for 5 years and can be uploaded in 2 separate files, the actual sample of use and a signed declaration of proof of use.
