In 1993, inventor Daniel Henderson became an apprentice of Dr. Kazuo Hashimoto and worked with him on licensing, management issues and infringement analysis. Unfortunately, their collaborative efforts were cut short in 1995 with Dr. Hashimoto’s untimely death.
A promise made.
Henderson turned his attention to keeping a promise he once made his mentor. He’d do everything possible to make sure Dr. Hashimoto’s work would be respected in the telecommunications and computer industries.
In 1996, Henderson and Hashimoto’s widow cofounded PhoneTel Communications, a company dedicated to protecting the patent portfolios of inventors including Dr. Kazuo Hashimoto, one of history’s most prolific inventors and the father of the answering machine.
A promise kept.
By successfully licensing nearly every telecommunications and computer company Daniel Henderson made sure Hashimoto’s work was respected and rewarded.
He has broad experience in the creation, management, and licensing of intellectual property. He holds numerous patents in telephony and communications.
Henderson was formerly with IBM Corporation and
received the "Distinguished Alumnus Award" from
Southern Oregon University.

Henderson worked with Jack Kilby, who received the Nobel Prize for Physics in 2000 for the invention of the world’s first integrated circuit (IC) chip, to study infringement of some of Hashimoto’s patents.
He currently presides over several companies including PhoneTel Patent Services, PhoneTel Communications and Pinpoint Incorporated. He has lectured on “The Power of the Patent.”
Henderson's many ties to the New Jersey Institute of Technology include establishing the PhoneTel IE Inventions and Patents Fund, the PhoneTel Endowed Graduate Fellowship Fund and involvement in creating a new course entitled “Inventions and Patents.” He was the commencement speaker when NJIT first presented the Hashimoto prize in 1998.
Henderson was invited to the Smithsonian Institution to accept a deed of gift for the many artifacts and early prototypes donated by PhoneTel.
