Anyone can write “patented” on a landing page. Below are the actual certificates, with numbers, dates and the issuing authority, reproduced at readable size so you can check them yourself before you place an order.

Relevant if you are evaluating a look-alike supplier — the exterior is protected independently of the mechanism inside it.
Certificates are reproduced as issued. Chinese-language documents are the originals; a certified English translation can be supplied with the commercial invoice on request.
A patent is a margin protection device.
When a product has no protected mechanism, the second factory to copy it sets the price and everyone races down. Three granted patents change that calculation in three concrete ways.
01 It slows the copycats down.
A granted invention patent on the mechanism means a competing factory has to design around it, not simply photograph it. That buys the first distributor in a market a window in which the product is genuinely differentiated — the single most valuable thing a new category can offer a reseller.
02 It supports a premium price.
A patented, documented product can be positioned as the original rather than as an unbranded import. That is the difference between competing on price against a marketplace listing and owning a category page of your own.
03 It survives due diligence.
Large retailers, rental chains and marketplaces increasingly ask for IP indemnity before onboarding a new category. A patent portfolio with verifiable certificate numbers is what makes that conversation short instead of endless.
How to check us.
We would rather you verified than trusted. Every claim on this page can be checked independently.
On the limits of patents. A Chinese patent protects the invention in China and, where separate applications have been filed, elsewhere. It is not automatically enforceable in your market. What it does give you is evidence of who invented the product and when — which is exactly what you need if a competitor claims you are the copy. Ask us about the status of protection in your specific country before making that claim in your own marketing.
