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, Electronic circuit 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 in the "Attorney or Agent" column of USPTO database, you can find the patent information handled by each Firm.
