Analysis of the 1753 patent families – top fifteen assignees with fifteen or more patent families, top Chinese academic assignees have many patent families, however these average below 2 patents per family, in contrast commercial assignees have on average 2.6 to 4.5 patents per patent family.

Patents per patent families analysis - all assignees

Note: This analysis based on patents published up until end of September 2018

Chinese assignees in general have 10 or fewer patents per family, while GB and US have as many as 27 and 30 patents per patent family.

In fact, these major differences reflect the assignees filing - in China many assignees hold only one or two patent families with one to two patents - the initial application plus the granted patent.

In contrast, commercial assignees tend to file more patents per families - reflecting the strategy to seek worldwide protection of the intellectual property.
