Anne Broache at CNET News writes about the disagreements among the small and large companies over reforming the patent system
link here. The big companies think it is a broken system, primarily because of the patent trolls which sit on questionable patents and extort money with the threat of litigation. The small venture firms oppose radical changes for adding uncertainty to the validity of issued patents. These differences emerged at U.S. House of Representatives Small Business Committee hearings on patents and a bill is expected to be introduced in both houses of Congress soon.
What the big companies propose is a less expensive alternative to litigation in order to review the validity of issued patents in a "post-grant opposition" process.
We will see what emerges. Several previous stabs at patent "reform" have expired for lack of support.
