This week, Robert J. Marks interviews Hal Philipp in a classic podcast from Mind Matters News.

Hal Philipp, inventor of the touch screen you use daily and over 80 other patented technologies, shares his extraordinary journey in an insightful interview. From pioneering touch-sensitive devices to combating corporate giants, his story is a masterclass in innovation, determination, and navigating the challenges of entrepreneurship.

Early Innovations and the Birth of Quantum Research

Hal Philipp’s path began with a passion for problem-solving. His groundbreaking work on optical sensors for automated doors and faucets laid the foundation for his career. These early projects showcased his ability to create practical, user-friendly solutions to everyday problems.

Later, Philipp delved into capacitive sensing, which consumes far less energy than optical sensors. This innovation addressed market demands for low-power, reliable devices, opening doors to applications in kitchen appliances, cars, and, ultimately, touchscreens.

The Touchscreen Revolution

Philipp’s touch-sensitive technology transformed the way we interact with devices. His key breakthrough was the development of a “QMatrix” capacitive sensing system. It enables multi-touch functionality at an affordable cost. This innovation made touchscreens ubiquitous, from cell phones to kitchen appliances like microwaves and ovens. However, Philipp acknowledges the unintended societal consequences, humorously lamenting how touchscreens on computers and cell phones have created a “planet full of zombies.”

Challenges of Patent Protection

Philipp’s journey wasn’t without challenges. He faced infringement from major corporations, including Apple, and unethical behavior from academics and competitors.  He sued Apple for the use of his touch screen on their legendary iPod. Defending his patents proved costly, highlighting the systemic challenges inventors face in protecting intellectual property. Despite these obstacles, he succeeded in licensing his technology to other global leaders like Motorola and Samsung.

Entrepreneurial Lessons Learned

Philipp advises budding entrepreneurs to build their foundation through collaboration, mentorship, or joining established startups. Reflecting on his 100-hour workweeks and legal battles, he cautions against solo ventures without financial and legal backing.
