Although good business sense should lead law firms toward legal technology innovation and investment, firms are largely static in their adoption of technology, said recent blog posts from Boston-based Blue Hill Research.

The three-part blog series called “Why Do Law Firms Struggle With Strategic IT?” was penned by David Houlihan, principal analyst at Blue Hill Research. Houlihan examines the last several years of the annual purchasing surveys from the International Legal Technology Association and legal tech blog InsideLegal. Legal tech spending is up from 2013 to 2014, according to the most recent survey. However, there has not been a significant change in IT spending or strategy since 2010, Houlihan said.
