Software Patent Drafting Lessons from the Key Lighthouse Cases

Obtaining a U.S. software patent is still harder than it was five years ago, but studying these “lighthouse” cases can improve one’s chances of success. While the Federal Circuit’s decision in Berkheimer v. HP Inc., 881 F.3d 1360 (Fed. Cir. 2018) and the USPTO’s guidance to patent examiners on the Berkheimer decision have recently improved the landscape for software patents, the following cases contain critical lessons for drafters that can further ensure claims are patent eligible.

Federal Circuit Upholds Thales Motion Tracking Patent Asserted against U.S. Government for Second Time

The recent Federal Circuit decision in Elbit Systems of America, LLC v. Thales Visionix, Inc. affirmed a final written decision issued by the Patent Trial and Appeal Board (PTAB), which upheld some claims in an inter partes review (IPR) proceeding challenging the validity of Thales’ U.S. Patent No. 6474159, titled Motion-Tracking and issued in November 2002. The patent claims a system for tracking the motion of an object relative to a moving reference frame using a first inertial sensor mounted on the tracked object, a second inertial sensor mounted on the moving reference frame and an element that receives signals from both inertial sensors to determine an orientation of the object relative to the moving reference frame. The resulting invention enables the use of inertial head-tracking systems for platforms including flight simulators and other vehicular applications.

Software Patent Eligibility at the Federal Circuit 2017

If there was a theme that emerged in 2017 it is the necessity to have what is specifically innovative disclosed in the claims. While not a particularly new concept, there were cases in 2017 where the Federal Circuit acknowledged that a patent eligible innovation may well have been disclosed in the specification, but which was not found in the claims. With many legacy software patents the description of the technology (if one actually existed) was only in the specification while the claims were written to be quite broad. The Federal Circuit requires both a thick technical description of the innovation and why it is an improvement (see Enfish) and incorporation of what is innovative into the claims… What follows picks up where my 2016 article left off and provides summary and analysis of the notable software patent eligibility cases decided by the Federal Circuit in 2017.
