a few large producers of components

Sure, CPUs and GPUs are pretty homogeneous, but that's also changing with Intel launching GPUs, Qualcomm entering laptop CPUs, Apple making their own silicon, and Nvidia potentially entering consumer CPUs (they're entering servers).

Making a new CPU, GPU, or storage device has a pretty high barrier to entry due to engineering costs (and yes, patents), but prices are pretty reasonable and planned obsolescence isn't really a thing.

I have never thrown out a CPU, GPU, or storage device because it broke too soon or got too slow, I threw it out because I wanted an upgrade. I have thrown out laptops because they became unusable due to terrible design (e.g. hinge got messed up on one, power connector broke on another, etc). So the ones with the most patents seem to be the ones that are the most reliable, whereas the combined product (laptop, appliance, etc) is the one that dies because they cheaped out on components. For example:

• washing machine - same relay died twice, and they went out of their way to make it hard to fix (epoxy on PCB, tiny plastic clips on casing, etc); I replaced the entire board for $100 instead of the one relay
• dishwasher - interface board busted, probably because of low quality caps or something; didn't bother diagnosing past "busted circuit board" because the repair people wouldn't touch it
• refrigerator compressor died twice (once under warranty)

If you go back 50 years, appliances lasted 20+ years, whereas now you're lucky to get 10. That has nothing to do with patents, it's just classic cheaping out on components.

The things that I have with tons of patents tend to last forever, it's everything around them that seem to fail and be incredibly hard to repair.

This means there’s demand for things easier to repair, but nobody’s making them. That’s because of barriers in the form of patents and licenses.

Not necessarily. The Fairphone exists and is pretty easy to repair, yet it's niche. Likewise with the Framework laptop. For washing machines (I just had to replace mine), durable options like Speed Queen exist, yet most seem to go for the cheaper, disposable option.

It has nothing to do with patents, people just prefer the cheaper or higher end option, and they're apparently not willing to pay a premium for repairability.

The right to repair movement is trying to expand repairability to all devices, not just those that cater to the repairability niche.
