He readily understands his clients’ complex products and electronic systems, and delivers rapid and sure-handed management of patent portfolios developed over nearly 20 years of exposure to computers, consumer, and industrial electronics and wired and wireless communication technologies.

Roger has been selected by the Chicago Law Bulletins Leading Lawyer Network as a “Leading Lawyer.”

Representative Experience

  • Filed and prosecuted patents for the HART Communication Foundation on a newly developed wireless communication protocol for use in various stages of process control systems such as those related to drug manufacturing and oil refining plants. The advances offered significant gains for the organization due to the new advantages it brought customers: more efficiency, greater flexibility, data safety, multiple points of connectivity and, of course, no wires to troubleshoot behind walls.
  • In the area of GreenTech, has filed and secured patents related to leading edge, waste water processing technology used in generating energy from landfill gases and industrial waste.
  • Working with our litigation team, filed a series of reexamination cases to reduce litigation issues regarding patents related to industrial power meters. Successfully had patents asserted against the company removed from the litigation by having the claims invalidated by the patent office, significantly reducing litigation costs.
  • Has developed and continues to maintain a large U.S. and international patent portfolio for one of the leaders in industrial and process plant control systems, including patents in the area of electronic control systems, communications, data management systems, sensors, and valve technologies.

Roger has handled matters in a wide variety of electronics-related technologies, including:

  • Computers—hardware and software
  • Digital communication and imaging systems
  • Design and implementation of consumer and computer electronics
  • Power meters and mass spectrometers
  • Power and process control systems
  • Laser, printing, and radar systems
