Spring 2014 (snippets)
Both Congress and the White House have been actively pursuing patent litigation reform in an attempt to combat the perceived “patent troll” problem. Of course, any legislation will impact all patent holders, even though most will not consider themselves to be patent trolls. The disconnect occurs because so-called “trolls” are being equated with all non-practicing entities (“NPEs”) , even though this includes a large number of entities to which that derogatory term was never meant to apply. After all, an NPE is simply a patent holder that does not commercialize the claimed innovation.
Winter 2014 (snippets)
Both the executive and legislative branches of the U.S. government have been working on patent reform. For example, the White House released a report last June entitled “Patent Assertion and U.S. Innovation,” accompanied by several executive initiatives and legislative recommendations. In addition, several pieces of legislation have been introduced in both the House and the Senate to address this perceived “patent troll” problem. As Sens. Leahy and Lee explained, the goal of such legislation is “to make it harder for bad actors to succeed, while preserving what has made America’s patent system great.” The difficulty is in narrowly crafting such legislation to specifically address the perceived problems without also ensnaring legitimate patent holders, and without introducing unexpected negative consequences for the patent system as a whole.

On May 3, 2013, the United States Patent and Trademark Office (“USPTO” or “Office”) Rules of Professional Conduct (“USPTO Rules”) went into effect to govern the ethical obligations for representing others before the Office. These new rules are based on the ABA Model Rules for Professional Conduct, and replaced the USPTO Code of Professional Responsibility, which dated back to 1985. Because almost every other U.S. jurisdiction had already adopted some form of the ABA Model Rules, this resulted in a harmonization of ethical standards. The adoption of the USPTO Rules was a significant event for every patent practitioner.

April 4, 2013 (snippets Alert)
The United States Patent and Trademark Office (“USPTO”) published its final rules in the April 3, 2013 Federal Register in preparation for adopting the new USPTO Rules of Professional Conduct (“USPTO Rules”). This is significant for any patent practitioner that has a USPTO registration number. Patent attorneys will no longer need to go back and forth between the old Model Code, as previously adopted by the Office, and the newer Model Rules, used by almost every jurisdiction in the U.S. However, Patent agents not accustomed to the ABA Model Rules will need to familiarize themselves with a completely new set of ethical obligations. We will highlight these changes in a future edition of snippets.

A number of comments were submitted when the USPTO first proposed these rules. One of the more contentious provisions involved the rules impacting the disclosure of confidential information, especially when that information belongs to a different client. The USPTO addressed these comments, and provided a potential solution should that ethical quandary occur. However, it did not change the proposed rules in response to these comments. This article provides an overview of these new rules, and describes the potential ethical quandary related to the disclosure of confidential information, and the USPTO’s response.
