IFixit has a good article on it. Basically they couldn't get it to pass wireless emissions standards the way they wanted to do it (put your phone anywhere on the pad to charge not, not directly on the circle, etc).

Would be quite rare for a patent dispute to go on behind the scenes. There were a lot of leaks suggesting mass production was due to start. I would bet production did not start, and that early production runs had low yields due to the complexity of the product.

Actually the opposite. Most patent disputes are resolved behind the scenes, long before anyone sues each other.

To my definition that makes it not a dispute! It's a commercial discussion with an agreement at the end of it.

Patent trolls send thousands of companies demands to pay royalties on a technology they never directly used. Fighting the troll costs hundreds of thousands, perhaps millions, of dollars, but they are only asking for $50k. Most companies begrudgingly pay. To me, that's still a dispute.

If it breaks down to the point a product gets cancelled, that would be a dispute. However yes, usually in such circumstances it tends to go public.
