InnoPath Software's over-the-air (OTA) solution recently saved KDDI the hassle of recalling handsets to fix a software application bug discovered on phones that had already been shipped.

Japan's KDDI says it was able send a patch to affected customers' handsets using InnoPath's DeltaUpgrade Plus OTA solution in about a minute's time. The software is designed to enable KDDI to "push" an update to customers without the need for them to do anything.

"Our ability to provide OTA firmware updates in a matter of minutes resides in our patented technology that produces the smallest possible update packages by calculating the difference in data packets between the existing and new version of the software," says Luosheng Peng, InnoPath's CEO, chairman and co-founder.

KDDI signed on as an InnoPath customer in June. At the time of the announcement, KDDI said it selected InnoPath's DeltaUpgrade Plus OTA solution for its ability to securely deliver OTA updates.

Earlier this summer, InnoPath, based in San Jose, Calif., announced a partnership with IBM to add its DeltaUpgrade Plus device management solution into IBM's WebSphere platform. The companies have said they intend to co-market and co-sell the combined solution to wireless operators and handset manufacturers around the world.
