FORT WORTH, Texas, Oct. 15 /PRNewswire/ -- PhoneTel expands its portfolio
of client companies by introducing Digital Packet Licensing, Messagetext
Licensing and Alphascan Incorporated as new customers.

Digital Packet Licensing owns patents relating to data, voice, and
wireless networks merging into packet-based infrastructures. The worldwide
voice-over-packet equipment market is growing exponentially as providers
migrate to converged voice, video, and data.
Messagetext Licensing owns text teletype writer (TTY) technology which
includes receiving, processing, and displaying caller identification
information for the hearing-impaired. This technology was developed by co-
inventor, Mr. Sydney Anders, President of Krown Manufacturing based in
Fort Worth, Texas.
Alphascan Incorporated owns the patent covering portable hand-held
translator/scanners. The patented features allow scanning entire lines of
text with the capability of viewing each word and hearing it read aloud. For
easy reading, a large-type image of the word scanned appears on the display
with the choice of having the words read, translated or spelled out.
Daniel Henderson, President of PhoneTel Patent Services Inc., said of the
announcement, "We are very pleased to add Digital Packet Licensing,
Messagetext Licensing and Alphascan Incorporated to the other clients we
serve. We remain committed to help support these companies in meeting the
complex challenges they face in licensing intellectual property."
