Project Minotaur Patent Liability Assessment

This project overview assesses the potential patent liabilities associated with a home security robot that operates through a web server, allowing manual control and intruder detection. The analysis focuses on three key patents: Gutmann's US0257910A1, Honeywell's EP2166375A2, and Fujitsu's US7218993. It highlights the similarities in technology for detecting planes and obstacle avoidance features, ultimately recommending licensing agreements to avoid infringement issues. The implications of direct and equivalent infringements are discussed for effective risk management.

  1. Project MinotaurPatent Liability Assessment Jon Roose for Team 16

  2. Project Overview • Home Security Robot • Interaction through a Webserver • Robot driven manually through house and spots intruders • Relays video to web interface using kinnect

  3. Software Hierarchy

  4. Gutmann - US0257910A1 • Filing Date: 03/17/2005 • Publication Date: 11/08/2007 • Inventors: Gutmann et. al. • Method and Apparatus for Detecting Plane, and Robot Apparatus Having Apparatus for Detecting Plane • Equivalent infringement • Abstract: Identifies planes for use in later algorithms and room mapping.

  5. Gutmann - US0257910A1 • Uses distance measurements to identify stairs for walking robot • Uses linear regression to find lines with planes • Uses lines to reconstruct planar surfaces • Similar to our system that detects wall and floor planes • Conclusion: Can’t design around, required to implement obstacle avoidance • Liability: Equivalent infringement • Recommendation: License patent

  6. Honeywell - EP2166375A2 • Filing Date: 09/10/2009 • Publication Date: 03/24/2010 • Assignee: Honeywell International Inc. • System and method of extracting plane features • Literal infringement • Abstract: Uses mathematical features of nearby 3d planes to determine orientation and motion of robot

  7. Honeywell - EP2166375A2 Our simulation of plane detection Patent Illustration

  8. Honeywell - EP2166375A2 • Identifies planes in 3d space using distance sensor • Calculates normals of planes in 3d space • Compares subsequent range images to determine motion and orientation of robot • Recommends pairing odometer with design • Used in UAV’s to minimize perspective distortion • Conclusion: Can’t design around unless we accept inaccuracies of odometer • Liability: Direct Infringement • Recommendation: License patent

  9. Fujitsu - US7218993 • Filing Date: 01/04/2005 • Publication Date: 05/15/2007 • Assignee: Fujitsu Limited • Robot system and autonomous mobile robot • Literal Infringement • Abstract: This is our project

  10. Fujitsu - US7218993

  11. Software Hierarchy

  12. Fujitsu - US7218993 • Home security robot • Patrols mapped area and records images/video • Streams images/video to external device • Recommends optional C&C server to communicate with external devices • Detects “suspicious” forms and alerts user • Uses processor for motion control • Designed as MARON-1 in 2002, phone controlled robot • Conclusion: Can’t design around, is our project • Liability: Direct Infringement • Recommendation: License patent
