Schopf & Weiss, a small litigation boutique that has grown at a rate of about one lawyer per year during the past 20 years, has picked up the pace this year, hiring seven lawyers, settling into a bigger office and launching a revamped Web site.

The Chicago firm could afford an investment in its business after a big payoff last year from one client helped provide what founding partner Bill Schopf said was the firm’s best-ever annual financial performance. The firm also benefited from selling the downtown Chicago building that housed its previous offices.
