Extract to table

To anticipate a claim, a prior art reference must disclose, either expressly or inherently, each and every limitation of the claim

I further understand that invalidity must be proven by clear and convincing evidence

The system must maintain pneumoperitoneum by preventing gas leakage through the trocar port

It must allow the smooth insertion and withdrawal of surgical instruments of various sizes

It must incorporate blade safety mechanisms to minimize the risk of unintended tissue damage during insertion

And it must be reliable, easy to use, and compatible with the ergonomic demands of laparoscopic surgical procedures
