There isn't a single, universally recognized symbol for a patent. However, the most common way to indicate a patent is by using the "Patent Pending" or "Patented" label. These labels usually appear on products or in product documentation.
Here are some other ways to indicate a patent:
- Patent number: This is a unique identifier assigned to each patent.
- "U.S. Patent" or "European Patent": These labels indicate the country or region where the patent was granted.
- Trademark symbol: While not specific to patents, a trademark symbol (®) can indicate that a product or design is protected by a trademark, which can be related to a patent.
It's important to note that using any of these labels without a valid patent can be misleading and potentially illegal.
