Now their investors are getting some money back by licensing the patents to the banks, so they'll (hopefully) be willing to invest in innovative startups that have to work with incumbents again.
Next time a small innovative company comes along, the banks are (hopefully) going to think twice before just deciding that they can easily re-implement their ideas.
This doesn't seem to me like a particularly good example of the patent system gone wrong. To me, this looks like exactly what the patent system is supposed to be: protection for those with innovative concepts, so that they can have the opportunity to commercialize their inventions without incumbents simply cloning their hard work.
