"The Waltham-based company, which makes software enabling service providers to push firmware updates to subscribers, now holds three patents in the U.S. and eight worldwide.
The new patents cover software that embeds a reverse-update option in every mobile software update, so that users and service providers can uninstall problematic upgrades or downloads and return a software package to its prior status.
A second patent covers software designed to ensure continuity in the upgrade process. If a phone loses power or shuts down during an upgrade, the software is designed to let the process resume at the cut-off point."
