Broaden your horizons when it comes to open innovation...
Most companies approach technology scouting as a linear process. They expect it to be an A-to-Z thing...start here, take these steps and you will end up here.
But this is the thing: Open innovation is not a linear process. It will never work cleanly every time. You can’t expect to define the problem, find the solution and then get rich (though that would be nice!).
Instead, what I tell companies I work with and consult for is that the need to broadly and completely develop their problem statements and then float them out to their networks (that we hope are relevant, well-developed and all those good things) and then wait.
And while you’re waiting, you still need to be scanning for ideas, solutions and technologies. You may find ideas, solutions and technologies that don’t directly or even indirectly address a current problem. That’s OK and to be expected, so don't wave them off because they aren’t relevant at that exact moment in time.
File them away, track them and keep them in mind. Then, when you encounter a problem down the road that matches up with that idea, solution or technology, you’ll be able to go through your mental files and match the newly-discovered or recently-articulated problem with that already-found solution.
Then you can match ‘em up as if you had planned it all along.
