Patents Granted by Office, Country of Origin
The World International Property Organisation (WIPO) says that after filing, a patent application is subject to search and/or examination procedure at the patent office.
The patent application is usually published before granting, and third parties may be able to file oppositions before or after granting.
The search and examination procedure normally starts soon after filing, but some offices request search and examination separately from the patent application, which may cause a delay of several years after the application. In some cases, applications may be abandoned before being examined or granted.
WIPO says the number of patents granted represents the number of patent rights established each year. However, the timing of the patent grants and the success rate at different offices can vary widely, and comparisons need to made cautiously.
The changing capacity of patent offices to examine and grant patents, or changes in time limits or examination practices can alter the number of patents being granted, and may not reflect any underlying trend in inventive activity.
