Patent US4022227 - Method of concealing partial baldness

By my reading of the five claims here, in order to be sued for this patent, you would need at least three sections of hair in your combover process (back and 2+ sides), you would need to comb over the back part before the sides, and you would need to put your hand down on each combed section as you applied hair spray.
Also, this dude would have to catch you doing it.
Now folks can publish their ideas, but others have to avert their eyes.
I suppose he could actually afford the royalties...
Your insight is really that it's impossible to write software because everything is patented, not so much because we're not aware of the patents. Anything we're aware of is patented!
It's also strategic to read patents and violate them anyway. The biggest takeaway from Apple v. Samsung was that other phone companies should have violated Apple's patents, and sooner.
Do you really think that these arbitrary specifics make it any more novel of an idea? The claims are the source of controversy even in software patents, because they are usually just as silly as the title makes them out to me.
That said, this has long since expired so Trump is safe.
However, just because you can utilize this patent without infringement, doesn't mean you should.
(The rest of us will thank you)
It expired in 1994, which was 17 years after the issue date, because the change in U.S. law to implement a 20-year patent term hadn't been enacted then [1].
