Well, Google actually started off with a WIN last month, because Apple's slide-to-unlock patent was invalidated in Germany. However, this wasn't a huge win. It was just one of numerous patents that Apple holds and besides, as we can see from Android smartphones nowadays, they have come up with alternative solutions.
Next came a LOSS for Google, as the ITC ruled that Android's text selection infringed on Apple's patents. This was not a major loss, but was still bad news for Google. After this ruling, Google faced some major defeats. As I have mentioned in my previous posts, several companies signed license agreement deals with Microsoft for its Android and Chrome devices. This means that these companies admitted that such devices of theirs were infringing on Microsoft's patents. While Google has not negotiated anything with Microsoft about this yet, I think we can expect to hear something about this in the near future.
There were several other cases in which Google had "minor" wins but "major" losses. Moreover, the author of this article mentions how the previous month for Google was as bad as it was for them last month. This seriously makes me raise the question, "Was Google's purchase of Motorola Mobility a waste?" I certainly hope not, not only because I like Google, but because they spent a lot of money on that.
