1) Under the current patent laws (US/EU/wherever) are new ICA algorithms the discovery of mathematical truths or the invention of new procedures to identify independent components of a mixed signal set?

2) Would patenting something in a saturated market be economical anyway?

3) If JADE or a FastICA variant were conceived/discovered today, could it be patented?

This is a more specific variation on : Are algorithm-based inventions patentable? - In which the answer is given is a general - Abstract algorithms can't be patented, but applications can be.

How abstract is too abstract?

  • You probably already know the Justice Thomas quote from Alice "We need not labor to delimit the precise contours of the 'abstract ideas' category in this case," – George White Apr 23 '18 at 2:05
  • Ultramerical (Ultramerical v. WildTangent) argued that the abstract idea exception is limited to well-known, fundamental, or routine concepts (patentdocs.org/2015/06/…). Ultramerical's patent being ruled valid twice before being ruled invalid show this is pretty murky territory. – jpg83 Apr 24 '18 at 2:48
