If you are a seller and suspect that other sellers are following your product, you can find follow-up products in the following ways:

1. Use Amazon search: Enter your product keywords on the Amazon homepage to search and find your product page.

2. Check "Other Sellers": At the bottom of the product page, you can see the information of other sellers. Click the "New" button to expand the information of all sellers.

3. Check the price and inventory: In the seller information, you can see the price and inventory of other sellers' products. If the price is similar or the same as your product price, it is likely to be a follow-up.

4. Check the seller name: In the seller information, you can see the names of other sellers. If there are duplicate or similar names among these names, it may also be a follow-up.

5. Use third-party tools: You can also use some third-party tools to find follow-up products, such as Keepa, CamelCamelCamel, Jungle Scout, etc.

If you confirm that other sellers are copying your products, you can protect your rights in the following ways:

1. Use brand registration: If your brand registration is successful, you can submit a stop-sale application to Amazon to ask Amazon to suspend other sellers from selling your products.

2. Use patents: If you have a patent-protected product, you can submit a patent complaint to Amazon to ask Amazon to suspend other sellers from selling your products until the dispute is resolved.

3. Submit a complaint: If other sellers use your brand name incorrectly when describing their products, you can submit a complaint of intellectual property infringement to Amazon and ask Amazon to terminate other sellers from selling your products.

When protecting your rights, it should be noted that before submitting a rights protection complaint, you need to confirm your rights first and provide sufficient evidence. If you cannot resolve the dispute on the Amazon platform, you can also consider resolving it through legal means.
