Occupy didn't result in direct action or changes. However, it popularized the notion of the One Percent vs. Ninety-Nine Percent, and got people to think about class in a nation very averse to even acknowledging the existence of economic classes. Probably had a positive impact in terms of helping Obama get re-elected, since Obama was lucky enough to get a seemingly clueless one-percenter as an opponent. Occupy had laid the groundwork which helped attacks against Romney.
The Trump protests have already had an effect. First of all, it's motivated normally non-politically active people into action. The sheer size of the crowds at the first protest, the Women's March, has had a galvanizing effect. People at the marches were encouraged to sign up to various groups. Those groups, like Indivisible or Planned Parenthood, keep things going by organizing at the local level and by giving them easy things to do each day or each week. There's a direct line between the protests and the fact almost every congressperson has an overwhelming volume of calls. And the seeds are planted not only for future protests but also for future direct action.
The administration has already backed down on some issues due to the protests. I think it's arguable the anti-LGBT executive order was scrapped at the last minute because of the sheer size of the instant protests over the immigration ban. If that many people would show up over an immigration order which didn't affect anyone they knew, then it would be reasonable to predict the streets would be absolutely flooded at any attempt to renew persecution of LGBT people.
As an added bonus, the protests are clearly unnerving Trump. I have no idea what the long term effect will be, but at the moment it's causing his team to make some errors.
