CalendarRules was spun out of OpenText in October 2007, building on the team’s experience creating LegalKEY’s Critical Dates product. From the beginning, our mission was to build a modern court rules service that could deliver accurate, up-to-date rules content to any product capable of consuming web services.

We started with a small group of early customers and partners who helped validate both the business and the technology. Since then, we’ve grown to service more than 2,600 legal organizations, including one in four AmLaw firms.

Our founding vision was simple: use modern web technologies to make court rules content faster, more reliable, and easier to integrate. By focusing deeply on the creation, maintenance, and delivery of rules-based content, we enabled our partners and customers to build stronger docketing, calendaring, and case management experiences around it.

In June 2021, CalendarRules was acquired by Clio, expanding our ability to bring trusted court rules automation to even more legal professionals.
