The search engine outfit claims that Microsoft-hired expert Robert Stevenson has seen the secret source code for its Android operating system and it never gave him permission. However it is unclear what Google is worried about. It might be concerned that Redmond is trying to widen the brief to get Android ruled a patent rip-off without it being there to defend itself.
According to Cnet, the row between Microsoft and Motorola is based on patent claims. Redmond thinks that Motorola phones running Google's Android violate its patents. The complaints with the ITC aim to keep infringing products and services from being sold in the US.
