The patent leadership loss was part of a number of failures. I've left (and my pay has doubled, go figure) but I was in a few IDTs and an MI. This was the situation.
1: the move to "global IDTs" resulted in the patent system being broken for over a year. Reviews were backlogged for ages. People stopped submitting; no reviews were being done, etc. A lot of the patents are driven by groups of developers. Break the pipeline and those groups fall apart. Even once you've fixed the pipeline, those groups won't just magically re-form.
2: periodically stating that plenty of areas are Search-1 only is fine. But when they're often your core business areas - and you're pushing folk to innovate in shiny areas that don't drive revenue - your priorities are a little skewed.
2b: Search-3 patents basically stopped being a thing with IDTs advised to mark them as publishes. The bar was raised significantly for budget reasons. It became harder, and less rewarding, to get less fancy ideas through which in turn reduced return on time investment.
3: the patent rewards haven't been updated in basically forever. $750 ain't what it used to be. (See also: salaries)
4: no one cares. The patent system isn't actually tied into development properly. Folks who engage are typically doing so because they need brownie points for STSM and DE requirements rather than wanting to do it to protect IP or develop it.
5: to a lesser degree, focusing patents on business value areas has been happening in the last year or so. I never really had any of the BS ones - but I know a few folks who just farmed it for income.
6: everyone's having to "do more with less" and that's cutting into time to develop IP, write disclosures or review them. Before I left, I basically stopped doing personal development education as there was no slack whatsoever in schedules. That /can/ work for a single code delivery - but having it more or less continual for a year fundamentally sabotages your workforce's career development.
When I left, the IP org was running around like headless chickens trying to figure out why our submission rate was way down. One problem is that the answers aren't very executive-friendly: they fundamentally broke the system.
Now they've lost the crown, I can only see the IP system being winded down and made less significant. It was one of the few measures IBM could say they were innovation leaders in.
It's a pity - IBM were cr-p with bonuses and it was one of the few ways you could get bright employees to put effort in and result in increased renumeration. Now, those employees will probably just put effort into finding jobs that pay well.
