PLI Advanced Patent Prosecution Workshop 2019



As Of Counsel, John Rauch brings with him 27 years of law firm and in-house patent prosecution experience.  John’s engineering background provides a sound base for the high tech focus of his career which has concentrated on helping his firm and clients to obtain the best possible scope of protection for their innovations. More on his background can be found in his firm bio on our attorney team page:

Outside of practicing law, John has taught as an adjunct professor. He also has an interest in becoming fluent in German and in traveling abroad.

John was recently featured in Condé Nast Traveler in an article about first time travelers.  John made his first trip abroad at the age of 55. He chose to visit Madrid, Spain where long-time favorite musician, Neil Young, was giving a concert. The article talks about why John had not traveled before, what encouraged him to start now, and what he learned from the trip.

John’s story was later shared by Condé Nast contributing editor, Mark Ellwood, on the Today Show.

The theme for the 2019 Conference in Palo Alto, “Global IP in an Increasingly Connected Yet Foreign World,” spoke to an area of concern for many companies and law firms.  As moderator for the “Strategies for Managing U.S. & Foreign Patent Prosecution” presentation, Ed Guntin opened the discussion with an overview of some of the challenges facing both law firms and inside counsel today.  The panelists (see list below) spoke about issues that had affected their companies and discussed strategies that could improve results while managing costs.

Topics covering proper management of international portfolios included:

  • Policy objectives for IDS submissions that
    - Avoids a deluge of submissions,
    - Satisfies duty of disclosure, and
    - Conforms to inequitable conduct standard
  • Techniques for avoiding inconsistent representations and statements in US and foreign prosecution that can result in surrendering claim scope
  • Balancing mitigation techniques against quality and cost
