Is an Autonomous Vehicle Patent War Revving Up?

Autonomous vehicles are paving the way as the next big innovation in personal transportation. With new technology, first comes the excitement of breakthroughs in any industry. Then comes the patent litigation arguments over who owns the technology and who can profit off the patents related to the technology. We are seeing this pattern again and perhaps the beginning of the self-driving cars patent wars. Earlier this year, the U.S. Court of Appeals for the Federal Circuit upheld the patentability of all challenged claims in a patent held by Velodyne LiDAR, Inc., one of just a handful of companies that makes LiDAR (light detection and ranging) systems for self-driving cars.

Defending Breakthrough Innovations – Protecting University Patents at the ITC

Many universities recognize the value of their patent portfolios and the need to protect their intellectual property rights from unlicensed and unfair use. When licensing negotiations break down, universities generally seek to enforce their rights in U.S. district courts, but overlook a potentially more favorable forum: the United States International Trade Commission (ITC). The ITC is a unique patent forum with experienced judges, defined patent rules, and statutory mandates to provide a timely resolution. More importantly, the ITC was designed protect U.S. industries, including the research and development performed at universities. This is not a hypothetical exercise: one university recently utilized the ITC, blazing a path that others can follow. As explained below, more universities should follow suit.

Federal Circuit Further Defines the Scope of Patent Venue

Recently, in In Re: Volkswagen Group of America, Inc., the United States Court of Appeals for the Federal Circuit (CAFC) further defined the level of control a defendant must exercise over an in-district agent to establish patent venue – i.e., where a case can be filed. The Federal Circuit held that the requisite control a principal must establish over its alleged agent in order to establish venue is “interim control”: day-to-day control over the manner of carrying out the specific actions for which the alleged agency relationship exists. Accordingly, in reversing the lower court, the Federal Circuit held that the dealerships in question were not agents of Hyundai or Volkswagen for the purposes of selling cars to consumers and providing warranty services. 

Energy Demand Response Programs and Patent Exposure

The core business model of energy producers and providers does not traditionally create significant patent litigation risk. Despite the complexity of the modern energy grid, the basic business and technology of energy generation has not changed significantly in the past 100 years. However, new programs, including residential demand response, executed via smart home appliances and controls, may expose utility companies to increased liability. Demand response programs allow utility providers to reduce grid load and energy pricing by offering customers pricing incentives to reduce energy usage during times of peak demand…. While such programs have been generally available for commercial customers, recently, demand response opportunities for residential customers have been expanding. Where these residential demand response programs allow energy providers to directly control, through the internet, consumers’ smart thermostats and appliances, energy providers may be exposed to patent liability.
