When I searched online for the name there were essentially zero results for it so I'm surprised it would infringe anything. I'm not sure how trademark law works so I'll look into this though, thanks!
I chose Creo because it means "to create" in Latin (I'm a sucker for Latin names), with docs obviously being short for documents.
I'd argue that Creo is just a generic word, it's not like the name is Leicadocs where that word is very firmly tied to a single company.
