Ref - <IMS patent >

The claims are the critical issue. The claims appear to describe emulation on any computer. Correct me if I am wrong, I fail to see the difference between the IMS patent and emulators developed for the IBM 360 to emulate older IBM machines.If I am right,it will be clearly invalid patent.

I would appreciate your comments and other people with knowledge of computer architecture like Scumbria.

I believe that many companies stopped patenting computer architecture. Computer Architects are very conservative, and make only small incremental changes.[ Most attempts at major change have been dismal failures like Fairchild SYMBOL, and Intel 432]. So advances in computer architecture have been a continuous succession of small incremental changes. It is difficult to patent small incremental change.

So if a patent examiner does not know the state of art and the history of computer architecture, and merely reads prior patents, he will approve a patent of something which is already known.
