In preparing the table, a patent search expert conducted a patent search using patent classification and keywords (as necessary) in order to extract patents in specific technical field (here, Hybrid Car field).
In the patent search, it was confirmed that a high-accuracy population (i.e., a population not including non-relevant fields) of patents was obtained. Subsequently, the population was used to create the table.

By entering the Firm name or Attorney name in the "Legal Representative Name" column of Patentscope (search system of WIPO), you can find the patent information handled by each Firm.
