Patent suit out of Tarpon Springs on US 5,067,932
Solomon Technologies, Inc. (Tarpon Springs, FL) filed a suit in federal district court in Tampa, FL alleging that the hybrid transmission drive in the Toyota Prius and Highlander falls within the scope of ("infringes") a number of claims contained in its U.S. Patent No. 5,067,932.
Relevant to issues of patent reform in 2005 (HR 2795), Solomon President Peter DeVecchis said "While we are aware of the difficulties faced by a small company seeking to protect its patent rights against a large company like Toyota, we are determined to use every effort to realize for our shareholders the benefits from our patented technology." Solomon is seeking an injunction and damages.
US 5,067,932 issued on Nov. 26, 1991, has been cited by 14 US patents, and claims no priority to earlier US patents. The first claim recites:
A combination motor and transmission device comprising
first power input means for receiving a first input of electrical power,
second power input means for receiving a second input of electrical power, and
power conversion means for converting said electrical power of said first and second inputs for output, said power conversion means including a mechanical power transmission unit, said power transmission unit having two inputs for respectively receiving mechanical power corresponding to said first and second power inputs provided to said first and second power input means and an output for outputting the converted power as rotational mechanical power,
wherein the rotational speed of said output is continuously variable, and said power conversion means includes, for each of said first and second power inputs, a respective integral combination of a respective electric motor element and an element of said mechanical transmission unit, each said integral combination involving said two respective elements thereof being directly associated mechanically and geometrically with each other without substantial spacing or other elements including bearings and shafts therebetween.
The summary includes the text:
An object of the invention is to provide an infinitespeed combination motor and transmission device, namely which can deliver peak power output with a continuously variable speed of rotation over a very large range of the rotational speed of the output.
Another object of the invention is to provide an infinite speed combination motor and transmission device having two inputs, at least one of the inputs being an integral combination of an electric motor element and a transmission unit element.
