"There are objective measures of code similarity that can be quoted, like the edit distance between abstract syntax trees, but here the expert hand identified the abstract steps that the code fragments were performing, made slides that nobody in the courtroom could actually read, filled with colored boxes outlining the purportedly analogous code in each case. In some cases, the abstractions he came up with were longer than the actual code they were supposed to be abstracting." This is because of the abstraction filtration comparison test that courts use: https://en.wikipedia.org/wiki/Abstraction-Filtration-Comparison_test https://en.wikipedia.org/wiki/Abstraction-Filtration-Compari... I think it's garbage too, but such is life. I don't think you can blame the expert for producing something that goes along with what the current law is.
