Last Updated: December 7, 2025
Welcome to www.lienyu.com (the "Site"), operated by Lienyu Jewelry ("we", "us", or "our"). We are committed to protecting intellectual property rights and ensuring compliance with applicable laws and regulations governing copyright, trademark, patent, and other intellectual property matters. This Intellectual Property Policy clarifies the ownership of intellectual property on the Site, your obligations when using the Site, and our procedures for handling intellectual property infringement complaints.

I. Ownership of Intellectual Property

All intellectual property rights related to the Site and the products sold thereon (including but not limited to jewelry designs, product images, logos, trademarks, service marks, trade names, slogans, textual content, graphics, page layouts, and software) are exclusively owned by Lienyu Jewelry or our authorized licensors. These rights are protected by international intellectual property laws and relevant treaties.

1.1 Trademark Rights

"LIENYU" and all related logos, service marks, and trade dress displayed on the Site are registered or unregistered trademarks of Lienyu Jewelry. Any use of these trademarks in any form is strictly prohibited without our prior written permission, including but not limited to reproduction, modification, distribution, or use in connection with goods or services not authorized by us.

1.2 Copyrights

All original content on the Site, such as product descriptions, blog posts, jewelry design drafts, photographic works, and video materials, is protected by copyright law. Except as expressly permitted by this Policy, you may not copy, republish, distribute, publish, display, transmit, or modify any of the aforementioned content without our prior written consent.

1.3 Patent Rights

Many of our jewelry products, including custom-made jewelry, products with unique craftsmanship, and products featuring innovative structural designs, are protected by corresponding patent rights. Unauthorized manufacture, sale, or use of these patented products constitutes patent infringement, and we will safeguard our legitimate rights and interests through legal channels.

1.4 Custom Jewelry Design Rights

Custom jewelry designs created by Lienyu Jewelry for customers are subject to special intellectual property protection. Unless otherwise agreed in writing by both parties, Lienyu Jewelry retains the core intellectual property rights to all custom designs, including design concepts, design drafts, and finished product design schemes. Customers are granted a non-exclusive, non-transferable license to use the custom jewelry for personal purposes only. Without our prior written permission, customers may not reproduce, sell, or authorize others to use the design.

II. Your Obligations

When using the Site, you agree to respect all intellectual property rights owned by us and third parties. You shall not engage in the following acts:
  • Use our trademarks, logos, or designs in a manner that is confusing, misleading, or infringing on our rights;
  • Copy, download, or distribute product images, design materials, or other copyright-protected content for commercial purposes;
  • Sell, resell, or reproduce our patented jewelry products without authorization;
  • Upload, post, or transmit any content on the Site that infringes the intellectual property rights of third parties;
  • Reverse engineer, decompile, or disassemble any software or technical systems used on the Site.

III. Intellectual Property Infringement Complaint Process

We take intellectual property infringement complaints seriously. If you believe that any content or product on the Site infringes your intellectual property rights, please submit a written complaint notice to our intellectual property department in accordance with the Digital Millennium Copyright Act (DMCA) and other relevant laws and regulations, which shall include the following information:

  2. A clear indication of the infringing content or product on the Site (including specific URLs or product page links);
  3. Your full name and contact information (address, phone number, and email address);
  4. A statement, made under penalty of perjury, confirming that you are the owner of the infringed intellectual property right or an authorized representative thereof;

Please send the above complaint notice to our intellectual property team via email at: ip@lienyu.com

IV. Our Handling of Infringement Complaints

Upon receipt of a valid infringement complaint notice, we will immediately initiate an investigation into the alleged infringing act. Depending on the actual circumstances, we may, at our discretion, take the following measures:
  • Remove the infringing content or disable access to the infringing product;
  • Notify the user who posted the infringing content and provide them with an opportunity to submit a counter-notice (if applicable);
  • Terminate the account privileges of repeat infringers in accordance with our Terms of Service;
  • Cooperate with law enforcement authorities in legal proceedings related to the infringement.

V. Counter-Notice Submission Process

If you believe that content you posted on the Site has been wrongfully removed due to an infringement complaint, you may submit a counter-notice containing the following information:
  1. A clear description of the removed or disabled content and its original location on the Site;
  2. Your full name and contact information (address, phone number, and email address), along with a statement consenting to the jurisdiction of the federal district court in the judicial district where you reside (or the United States District Court for the Southern District of New York if you are located outside the United States);
  3. A statement, made under penalty of perjury, confirming that you have a good faith belief that the removal or disabling of the relevant content was due to a mistake or misidentification;
  4. Your signature (either electronic or handwritten).
Please send the counter-notice to the following email address: ip@lienyu.com. Upon receipt of a valid counter-notice, we will restore the removed content within 10 to 14 business days, unless we receive notice that the complainant has initiated legal proceedings against you.
