Our disappearing world

Remember the good old days?

When you walked into your garage and saw a solid physical object known as a garage door opener?

Sorry. It's not there anymore. It has been teleported into the abstraction dimension (a neighborhood of the Twilight Zone) by the astute judges of the Federal Circuit.
THE CHAMBERLAIN GROUP, INC. v. TECHTRONIC INDUSTRIES CO. LTD [OPINION Fed. Cir. - PRECEDENTIAL 2019-08-21]

According to the Fed. Cir., adding a wireless status reporting device to your garage door opener (more generally, your "barrier operator") is an abstract act that is not patent eligible.

What's being teleported away from us next? The kitchen garbage disposer? NO ooohhhhh.....

Dice-Secting Reality

The dicey illogic of Alice/Mayo continues with IN RE: MARCO GULDENAAR HOLDING B.V. (Fed. Cir 12-28-2018)

Normally it is the Fed. Cir. that accuses inventors of claiming a result without specifying exactly how it is achieved.

This time however, a role reversal is undertaken. It is the Fed. Cir. that dissects a claim so to only see the result without acknowledging exactly how it is achieved in accordance with the claim.

For more details about the specifics of the case you can link to here.

That aside, the real question is by what authority can the Fed. Cir. dissect a claim so as to pick and choose only the parts that will support their conclusion that the "only" novelty is "printed matter" and that the so-labeled "printed matter" has no relation to the substrate?
