Kirkland ranked in fourth place for contentious patent work,landing four places higher than the next ranked multi-practice outlet. This is the first time that all U.S. firms have been featured in the same list. In previous years, the U.S. was divided into three regions - West, Central, and East. Nomination forms were sent to close to 4,000 IP specialists in private practices and companies in more than 100 countries.
