IBM's IP revenue has been dropping over the past few years

IBM was awarded 7,355 patents in 2015 which was the 23rd year in a row it has received the most patents. Over 2,000 of last year’s patents were related to cognitive computing and the company’s cloud platform. Over the 23 years IBM has received over 88,000 patents and I would estimate they have generated about $20 billion or more of IP (intellectual property) related revenue.
