I don't understand...
"The consultation paper states that the changes have been sought due to government concern over “evergreening”- a strategy in which companies could use innovation patents to effectively extend the life of their patents."
I am not a patents lawyer, so I do not understand how an innovation patent extends the life of an existing patent.
I have patent A, which describes a process.
I have patent B, which describes an improvement to the process in Patent A.
Surely Patent A can expire without invalidating Patent B - in other words, W&D can now use the process described in Patent A so long as they do not use the improvement described in Patent B.
So how the hell does the "improvement" extend the original? Or were the lawyers and politcos complete f*-wits when they drafted the legislation?
