The term “utility right” does not have a universally recognized or specific meaning. However, based on the context of intellectual property and patents, it might refer to a “utility model” or “utility patent.”

1. Utility Model: A utility model is a type of intellectual property protection similar to a patent but with some differences. It provides legal protection to inventions that are typically of a lower level of innovation or complexity compared to those eligible for standard patents. Utility models are often used in countries where the threshold for patentability is lower, and they offer a shorter protection period than patents. They are intended to encourage innovation in areas where technological advancements might be incremental.
2. Utility Patent: In the United States, a utility patent is the most common type of patent. It is granted for new and useful processes, machines, manufactures, or compositions of matter, or any new and useful improvement thereof. Utility patents provide exclusive rights to the patent holder to prevent others from making, using, selling, and importing the patented invention for a period of usually 20 years from the filing date.

Please note that the specific legal definitions and terms related to intellectual property rights can vary from country to country.
