Google insists it did not copy the iPhone feature.

Hiroshi Lockheimer, Google's vice president in charge of Android, was invited to the trial where Apple accused Samsung of patent infringement.

Apple claims Samsung may have illegally used up to 50 of its patents, but due to limitations in a single lawsuit, they only selected five. Conversely, the South Korean company has proven that four of these five patents (excluding "Slide to Unlock") are features already present in Google's Android operating system, not something Samsung developed itself.

Therefore, Google's Lockheimer was invited to the trial to share about the development of Android. "We want to create our own unique identity. We value our own ideas and are very passionate about what we are doing," Lockheimer said.

Google claims they developed many features on Android before Apple announced the iPhone.

Lockheimer joined Google in April 2006, when the Android development team had only about 20-30 people; now that number has grown to 700. "People still know Google is a big company, but we were just a small team, and Google allowed us to do everything ourselves," Lockheimer said. They built "thousands of features" on Android with the goal of making it as easy as possible for people to use their phones. Many features were initiated as early as 2005 (the year Google acquired Android), even before the operating system appeared on HTC phones in October 2008.

Samsung's lawyers wanted to call 17 witnesses on Monday, April 14, but Judge Lucy Koh ordered them to shorten the list. Many of the figures on the list were Google executives, and Lockheimer was the first witness.

Last week, Apple presented its reasons for suing Samsung and finalized the amount it is seeking in compensation at $2.19 billion. Meanwhile, Samsung is also suing Apple for infringing two patents related to image recording, reproduction, and remote video transmission (such as FaceTime) and is demanding $6.9 million.

Although both companies have mentioned substantial compensation, the lawsuit isn't simply about money. Two-thirds of Apple's revenue comes from iPhones and iPads. They own the world's best-selling smartphone, but the largest mobile market share belongs to Android, and the largest Android phone manufacturer is Samsung.

Apple claims the lawsuit is unrelated to Android, but Samsung insists Apple's target is a "holy war against Google." Suing Google directly wouldn't benefit Apple because Google doesn't manufacture phones and tablets itself. Instead, Apple is attacking companies that sell Android devices, especially Samsung – the world's largest phone manufacturer.

The trial between Apple and Samsung will last until April 30th, after which the jury will convene and deliver its final verdict.
