IBM has stopped innovating a long time ago, I would guess sometime in the late 1980s<p>IBM is also the biggest Patent Troll on the planet[1]. I met a Patent and IP Lawyer at a Code Camp in San Luis Obispo. He said he did Legal Patent and Licensing work for IBM for many years and claimed that they generated over 1 Billion $ / year just from their Licensing deals and patent enforcement alone, and that it was their biggest source of income.
I tried to see if those # in his claim were true, and it looks like they are, even to this day.<p>> Between 2008 and 2012 IBM’s patent portfolio generated between $1.1 and $1.2 billion per year.<p>Source: <a href="https://www.forbes.com/sites/chuckjones/2016/01/19/if-patents-are-so-valuable-why-does-ibms-intellectual-property-revenue-continue-to-decline/" rel="nofollow">https://www.forbes.com/sites/chuckjones/2016/01/19/if-patent...</a><p>[1] Source: <a href="https://thumbor.forbes.com/thumbor/960x0/https%3A%2F%2Fblogs-images.forbes.com%2Fchuckjones%2Ffiles%2F2016%2F01%2F2015-Patents-IBM-vs-Competitors.jpg" rel="nofollow">https://thumbor.forbes.com/thumbor/960x0/https%3A%2F%2Fblogs...</a>
