Pietragallo Gordon Alfano Bosick & Raspanti has shed its patent prosecution group, which is relocating to Pittsburgh-based Leech Tishman Fuscaldo & Lampl.

Leech Tishman announced Tuesday that it was adding the five-lawyer IP group to its Pittsburgh office. Leech Tishman managing partner Pete Fuscaldo said the firm had set out to find an IP group in Pittsburgh that would complement the firm’s existing IP practice in California.
