Not invented here

Judge for yourself!  Another view of inventorship from the UK Court of Appeal.  In Markem the Court of Appeal decided to ignore the claims in deciding what the inventions were, and discount the fact that the idea for the invention had first been made at the inventor's previous employers.  Why?  They found that what had been done at the previous employer was non-confidential wish-list, which was not then an invention; not until a method of implementing it had been devised.
