Cantor Colburn is #7 Firm in the US Patent Applications Claiming Foreign Priority

August 2, 2022

Cantor Colburn is #7 among U.S. law firms for the most U.S. patent applications filed claiming foreign priority.

In its August 2, 2022 publication, "Top Patent Firms for Foreign Priority Applications," by Sarah Garber, Juristat analyzed the filings of medium-large firms to determine which firms filed the most applications claiming foreign priority in the 3-year period of 2018-2020, defining medium-large firms as those that filed more than 750 applications during this three-year period.

"Finding an IP firm with experience claiming foreign priority is critical for companies based in or working in foreign markets," Garber write. "Here, we rank the top firms for foreign priority applications, based on volume. When we publish our annual Top Firms rankings, we’re often asked why we exclude applications claiming foreign priority from the analysis. After all, it is a crucial service (and revenue stream) for many firms. The simple answer is that, for those rankings, we’re taking other data points (allowance rate and office actions) into consideration, and including applications claiming foreign priority alongside non-foreign priority applications can skew those metrics, impacting the results. But intellectual property firms that work primarily – or in some cases, exclusively – with foreign entities deserve recognition, too."

Cantor Colburn is one of the top intellectual property law firms in the U.S., offering superior patent, trademark, copyright, transactional and litigation services to clients worldwide.
