She filed a patent extending her innovations in information-transfer systems.
On September 13, 1962, Evelyn Berezin filed U.S. patent application US 3,256,514, titled "Information transfer system." This filing extended her earlier work on data transfer apparatus into a broader systems-level framework for moving information across computing networks.
By the early 1960s, Berezin had established herself as a leading voice in the design of information-handling architectures, work that placed her at the intersection of hardware engineering and what would later be recognized as systems and network design. The concept of an 'information transfer system' anticipated the kinds of networked computing environments that would become standard decades later.
This patent is historically notable as part of the continuous arc of innovation that led directly to Berezin's most famous professional accomplishment: the design of an early computerized airline reservation system for United Airlines. Such systems required exactly the kind of information transfer infrastructure she was patenting here, connecting ticket agents across the country to a shared central database in near real-time—a revolutionary capability for the travel industry in the 1960s, and one built on the technical foundation she had spent years developing through her patent work.
