IP in terms of people's behaviour or their political decision?

In terms of behavior - the scheme is MEANT to encourage innovation. I hesitate to answer how well the system does in fact do so since the cost of maintaining your IP outweighs the benefits for all but the largest companies. At least one element I see that could be changed is the way employees' innovations are the property of their employers in the majority of cases; an example where it would remain property of the employee is where its arms length from anything the company is involved in. So it can in effect have a chilling effect on innovation but doesn't necessarily need to, at least in my opinion.

In terms of politics - im not sure. It's one area where policy makers seem to bridge political divides, but as far as what that means - idk? I'd love for a political studies graduate to answer what that indicates!

For the second point: An even more interesting example (imo) is that even Russia seems to have concluded it's necessary to "protect" American IP [even after the invasion of Ukraine] to the extent it's necessary for the Russian public as a means of not being confused by brands and for Quality control. I think the rationale is that Russians might not want to support American companies and Russian owners shouldn't be "lazy" in just copying an American trademark (imagine a person not wanting to support McDonald's and instead stops supporting the Russian company DcMonalds)
