The first full day of Samsung's defense began by suggesting Google is responsible for much of the disputed software features on its handsets. Google software engineering managers for search, email, and other Android features testified they were responsible for some of the features in question and that they did not copy Apple's software.
For example, one patent covers a feature that searches both the Internet and data on a handset. A google engineer described the process for developing similar functions in Android but noted "on device [search] is only used about 2% of the time."
Another Google software engineer testified about her work that started in 2006 on functions similar to Apple's quick links patent. The patent describes ways of finding phone numbers, addresses, and other information in random text and presenting users appropriate options for making a call or sending an email, for example. Much of the testimony tried to establish differences in ways the so-called quick links are implemented as a defense against infringement.
Apple attorneys noted several times the case is focused on Samsung because it received the revenue and profits from the handsets accused of infringement. One Google engineer pushed back on that argument saying, "Everything I described here you really need to use or else you will break applications in Android."
A third Google engineer described Gmail and Android mail applications and ways the independently developed features are similar to Apple's patented background synchronization.
About $507 million of Apple's total $2.191 billion in requested damages depend in part on an assumption Samsung would lose sales for four months if it had to design around the Apple patents. At least two of the Google engineers said changing the way some of the features in question are implemented could take less than a day.
The defense began late Friday when Google's engineering manager for Android said the search giant did not copy Apple's patents. Samsung has yet to present its case that Apple infringes two of its patents. The trial is expected to continue through the end of the month.
