Patents aid in genocide.

There are hundreds of thousands of industrial processes that we need to change and innovate to combat climate change. Any small innovation will be patented and then potentially exploited to extract the maximum amount of profit. This reduces the pace of innovation generally, and makes greener more energy efficient solutions slower to be adopted.

Similar can be argued about advertising in general of course, they lead to more consumerism and more resource and energy use and why first world has such insane GHG per capita.
