This isn't good for academic research or for the development of AI by companies. The patents are on very specific things invented by Geoffrey Hinton's team like using drop out during training, or modifying data to provide additional training cases, but also include very general ideas such as classification itself. If Google was granted a patent on classification it would cover just about every method used for pattern recognition! You might make the charitable assumption that Google has just patented the ideas so that it can protect them — i.e. to stop other more evil companies from patenting them and extracting fees from open source implementations of machine learning libraries. Google has just started an AI arms race, and you can expect others to follow.
