Google recently purchased 217 patents from IBM, including 28 published patents and 188 of IBM’s granted patents. The transaction was posted in the United States Patent and Trademark Office’s assignment database on Tuesday. SEO by the Sea said the patents are related to email administration, IM apps, video conferencing, presentation software and more. It remains unclear how much Google paid for the patents, but the company also purchased 1,000 patents from IBM in July of last year and another 1,023 in September. Google is currently in the process of acquiring Motorola Mobility as well, which has a vast patent portfolio that Google said will help it defend its Android partners from patent lawsuits filed by litigious competitors such as Microsoft and Apple.
