Answer:
Trademark
Step-by-step explanation:
A trademark is an intellectual property which consists of a particular design aimed at identifying a product as being from a particular source.
Once a trademark is established on a product other companies will be unable to use that technology nor design without purchasing rights to use the trademark.
Apple first introduced Solfie which is a name coined for slow motion selfie on their iPhone 11.
In order to avoid competition with Samsung, Google, and others they trademarked Slofie thereby preventing competitors from using similar technology
