Thanks, Wolf, for the link - but it's even more interesting to read the comments...
Together it gives you the impression that "our" infringers knew exactly what they were doing when they started the re-exams for the MMP: They were sure the USPTO - regardless if it is because of incompetence, financial shortage or bureaucratic complexity - would not be able to decide it in a regular timely manner.
And now it's more than half a year the latest '336 re-ex has started without anything happening. If the goal of the companies was to win time their lawyers did a perfect job by using the USPTO's weakness.
Does the US know how important inventions are for its future?
