Defending a Patent: Lessons from Tech Entrepreneur Hal Philipp
In Part 2 of a 3-part interview, Philipp — inventor of the modern touchscreen — tells Robert J. Marks and Bradley Norris about his struggles with AppleWhen we swipe a phone or tap a touchscreen, few of us realize how much engineering — and legal grit — underlies that simple gesture. In an interview with Mind Matters podcasting, inventor Hal Philipp traces the path from lone tinkerer to successful founder, and finally to weary veteran of patent warfare. Philipp, a key inventor behind modern capacitive sensing and touchscreens, delivers a sober message for innovators: invention is only half the battle; defending your invention can define your company’s fate. From Single-Point Touch to a Full Touchscreen Philipp’s early work focused on single-channel capacitive sensors — one-button touch or proximity detection.
