Roy Hofer celebrated his 78th birthday Thursday—a day after launching his own solo shop and a month after leaving the firm that was his professional home for more than 50 years.

A veteran intellectual property lawyer and past president of the Chicago Bar Association, Hofer was until last month a name partner at the Chicago-based IP boutique long known as Brinks, Hofer, Gilson & Lione, having joined one of its predecessor firms in 1961.
