Trademark Notice

1. Brand identifiers and ownership

益序, Esio, associated logos, product family names, taglines, and other brand elements are trademarks and brand identifiers owned, used, or applied for by Xiamen Esio Biotechnology Co., Ltd. Registration status is determined by the official records of the relevant jurisdiction.

A registered-trademark symbol is used only for marks registered in the applicable territory. The absence of a symbol does not waive Esio’s rights.

2. Fair reference

Media, customers, and partners may make accurate textual references to identify Esio products. They may not alter logos, imitate brand presentation, incorporate the brand into their own name or domain, or imply an unauthorized partnership, certification, or endorsement.

3. Distributors and partners

• Obtain written permission before using Esio logos, product images, or marketing materials and follow current brand and promotional review requirements
• Do not change logo proportions, colours, or typography or combine Esio marks into a new logo
• Do not register a company name, domain, social account, shop name, or other identifier containing 益序 or Esio
• Do not use brand assets outside the authorized territory, product, purpose, or term, or create unreviewed performance, clinical, or regulatory claims

4. Third-party marks

Other company, product, and platform names belong to their respective owners. References may describe compatibility, connectivity, or sources and do not by themselves indicate affiliation or endorsement.

5. Permission and infringement reports
