Like many IP boutiques, Philadelphia-based Synnestvedt & Lechner had a long history. Its roots went back 111 years, and clients included Honeywell International and IBM.

Today, Synnestvedt is no more. Following a series of partner departures and layoffs, the firm disappeared into merger, with Fox Rothschild acquiring the majority of its remaining lawyers — eight attorneys, including managing partner Joseph Posillico. A three-lawyer group will join Ballard Spahr Andrews & Ingersoll. Another partner is now at Stradley Ronon Stevens & Young.
