I would say certain types of problem domains will be more likely to find solutions in academia vs companies.

For example, it's going to be pretty hard to get much innovation from academia in the area of operating planet scale networks/datacenters simply because they don't have access to such environments and the money to support it nor the day to day challenges of actually running something like this.

That said, much of innovation happening in companies is likely part of the secret sauce that makes the company successful so we're not going to see much of it make it out at the time the innovation takes place but over time companies and people working for them do open up about their solutions.
