Taking one of IBM's patents as revealing of their overall strategy is like watching a guy scratch his toe and concluding that he probably wants to amputate his leg. There's just no way to connect your observation to any evidence for (or against) the conclusion.
Patents incentives were also roundly ridiculed by lower band and longterm employees at IBM. For individual contributor types, there was some expectation that patents were part of the job description.
"...you end up with a barbell distribution – a bunch of those rare people who can work through systems they’ve never seen before and fix them at the top, and a bunch of people to act as interchangeable cogs at the bottom..."
If you cannot quickly add value to systems & technologies you've never seen before, you're probably a depreciating commodity. IBM is merely riding this wave.
