dgharmon writes "A brief recap: In March, I wrote about a lawsuit that posed a threat to my daughter’s voice. Maya, who is four years old and unable to speak, uses an app called Speak for Yourself (SfY) to communicate, and the creators of SfY were being sued for patent infringement by Prentke Romich Company (PRC) and Semantic Compaction Systems (Semantic), two much larger companies that make designated communication devices (not iPad apps)
"In connection with the settlement, Semantic has agreed to grant a non-exclusive license as to two of Semantic’s patents, i.e., U.S. Patent Nos. 5,748,177 and 5,920,303"
"A dynamic keyboard includes a plurality of keys, each with an associated symbol, which are dynamically redefinable to provide access to higher level keyboards", U.S. Patent No. 5,748,177
"An apparatus, comprising: integrated input and display device for displaying a plurality of keys of a displayed keyboard", U.S. Patent No 5,920,303"
