Do I understand the Markman Hearing correctly? The contension is over the terms and language used in the original patent? This hearing by the judge (as opposed to using the jury trial) is to sort out certain precise meanings?

The jargon or language of chips, memory, and operating systems will be limited, modified, or what? One more time can someone summarize what happens at a Markman Hearing in general AND what are we looking for specifically? ORY
