While regulation is a problem, I think the European public innovation funding system through government grants is a bigger problem. Almost any R&D is partially funded by grants, which means any innovation idea also has to be sold to a board of bureaucrats. There will also be rules affecting things like the maximum salary they will reimburse per employee, which means businesses won't pay for top level talent. Finally, the whole process is a huge waste of human resources on both the companies' and government's side, to the extent that it has spawned a cottage industry of professional proposal writers who take sizeable commission.
