In a country of frivolous lawsuits, getting sued is almost meaningless. Big companies are sued for all sorts of bullshit all the time. Check back if and when there’s something concrete.
Through outside of patent and copyright law very many of the law suites commonly brought up as "frivolous" are actually very reasonable law suites and both the reason they are well known and them being known as "frivolous" is because of company propaganda so that they can push for more forced arbitration.
I think it was FUBAR before Pat came back. That was always going to be a tough ship to right. I'm not sure how much you can credit him with stumbles and successes since, but at least Arc is looking decent with the most recent release. I also think the 285k and ilk aren't such bad chips as a first foray into external fabrication. They're strong all-around performers despite some minor regressions, and they're working in a smaller power budget.

To be fair that really remains to be seen. It took them how many years to ship a single decent card? Sure it's very competitive with last gen Nvidia and AMD GPUs but it's not clear if that's the case only because Intel is willing to sell them with very low margins or even at a loss.
