What is the definition of Patents Macabre?

Ah, the term 'patents macabre' is like a macabre comedy of errors - a bizarre fusion of the morbid (the morbid being inherently morbid) and patents, which are typically associated with innovation and progress. Now, imagine this in a hilariously unsettling way: "The patent office decided to patent the idea of turning pet cries into popcorn - a macabre patent that's probably going to take us all to the haunted asylums of the future."
