The following tables of the top representative filers in various jurisdictions were kindly compiled and supplied by Corsearch, using Edital’s IP Statistics Module (www.corsearch.com).

To gather data for the WTR 1000, Corsearch supplied a list of the top 25 filers (representatives/correspondents) for the 12 months to August 30 2011 in the selected jurisdictions. Across all of the tables, analysis was undertaken to ensure that only representative filers at law and IP firms were featured, rather than brand owners (which were eliminated where they were reported by a trademark office).

In certain jurisdictions (ie, the Czech Republic, Hungary and the United States), the name of the individual who carried out the filing, rather than the firm name, was returned as the reported correspondent by the national office. The tables for these three jurisdictions thus present the individual representative attorneys as named by the respective office, along with their firm affiliation, rather than the top filing representative firms.

In all instances the data reflects the top-named representative filers as explicitly reported by the trademark office. Hence, in the table of Italian representative filers, BARZANO & ZANARDO MILANO SPA and BARZANO & ZANARDO ROMA SPA appear as separate entries because they appear under slightly different names in their filings. Similarly, where a firm registers trademarks using a variety of correspondent names in a single jurisdiction or international system, these will have been reported separately as they are on record with the national office, rather than being combined to create a single entity. In all instances the data has been presented as directly reported by the national office and has not been manipulated to consolidate registrations made by a firm or group under different names into single entries.
