Boston giant Hale and Dorr has weathered the current slump in its core technology market to deliver a 10% increase in turnover.

The 500-lawyer firm’s fee income hit $337m (£187m) in 2003, against $306.5m (£170m) the previous year, with average partner profits static at $810,000 (£450,000). The top 50 US firm put its failure to increase profitability down to its acquisition of the European joint venture practice that it had run with Brobeck Phleger & Harrison until the San Francisco firm’s dissolution last year.
