The Season of Innovation

Anyone has stats on when, during the year, most actual innovations are dreamt up, or brought to light ..?

Just wondered, pondered, looking outside into a greyish dawn, and thought: Where are this year’s Innovations that make late fall / winter time more amicable ..?
Just because seasons are only a quarter of the year ;-| doesn’t sound like a good explanation; whereas any year, or innovation’s adoption wave, is a one-time thing only, seasons tend to re-appear quite regularly over and over again through the ages. So any real innovation might stick even better. [Will now halt this silly argument.]
Then again, can we pinpoint the exact moment an innovation is conceived, even when delivery may take some time (possibly, spanning a year) ..? Can we spot seasonal patterns ..? One could imagine that Nature’s recurrence and bloom, impacts the mind in similar ways. *waves.

So, if any of you Big Data lovers out there would have a nice graph, I’d welcome it. Plus:
