> (i) relate at the time of conception or reduction to practice of the invention to Google’s business, or actual or demonstrably anticipated research or development of Google

That's the catch. Not related to what _you_ do at Google, but related to _anything_ that Google does. Pretty much all the stuff I wanted to work on in my spare time while employed at Google could be seen as related to Google's business/research, as Google does a lot of things. And that's how Google seems to read this too, considering how the Open Sourcing documentation [1] is written.

Because Google’s business interests are so wide and varied, this likely applies to any personal project you have. That includes new development on personal projects you created prior to employment at Google.”
