A good and patentable idea can be central to a product, but inept development can wreck the best of ideas. The Lintech electron beam tester was based on a patented idea of their boss, whose name was on the patent (which he'd got to own). He cheap-skated on the development to such an extent that one of his ex-engineers was able to build a pretty much identical machine which destroyed his business - nobody ordered a Lintech machine after the Schlumberger competitor hit the market, and after Lintech had delivered the last of the machine it had sold they went bankrupt. Mike Engelhart - of LTSpice fame - worked on that project. >>> Some people invent things.

You seem to have got your name on exactly one patent, taken out by a group you were working with, so your grasp of what constitutes a patentable idea and what you can do with it does seem to be second hand. -- Bill Sloman, Sydney
