The ABA rejects efforts to undermine the courts and the legal profession. Read full message: www.americanbar.org/news/abanews...
We speak today on behalf of the legal profession and its members who seek to live by the oath each took upon admission to the bar.

We reject efforts to undermine the courts and the profession. We will not stay silent in the face of efforts to remake the legal profession into something that rewards those who agree with the government and punishes those who do not. Words and actions matter. And the intimidating words and actions we have heard must end. They are designed to cow our country’s judges, our country’s courts and our legal profession. These efforts cannot be sanctioned or normalized.

There are clear choices facing our profession. We can choose to remain silent and allow these acts to continue or we can stand for the rule of law and the values we hold dear. We call upon the entire profession, including lawyers who serve in elected positions, to speak out against intimidation. We acknowledge that there are risks to standing up and addressing these important issues. But if the ABA and lawyers do not speak, who will speak for the organized bar? Who will speak for the judiciary? Who will protect our system of justice? If we don’t speak now, when will we speak?

The American Bar Association has chosen to stand and speak. Now is the time for all of us to speak with one voice. We invite you to stand with us.

Agree. Important to recognize that PERA amends the threshold test for eligibility under § 101, and does not remove the patentability requirements for novelty under § 102 or nonobviousness under § 103 Patent-eligibility vs patentability, completely different things
