When copying has occurred, much of the code may have changed by the time it’s examined due to the normal development process or to disguise the copying. For example identifiers may have been renamed, code reordered, instructions replaced with similar instructions, and so forth. However, perhaps one comment remains the same and it’s an unusual comment. Or a small sequence of critical instructions is identical. Correlation is designed to produce a relatively high value based on that comment or that sequence, to direct the detective toward that similarity. If correlation were simply a percentage of copied lines, the number could be small and thus missed entirely among the noise of normal similarities that occur in all programs.

The reason giant companies hate patent trolls is because they are not capable of being counter-sued. There is no deterrent effect because patent trolls do not make, use or sell anything, they just sue. So giant companies are targets in the same way that smaller companies without patents are targets of big companies with patents. No one should aspire to be a target. A simple truth is that a small business without patents might as well dress themselves up as a buck during hunting season complete with a bulls-eye pre-drawn. So here is the case for every business to get patents, particularly software patents. Ignore it if you like, but you do so at your own peril.
