Re: Patentable claim

Wayne,

The topic of patent application and approval is an interesting one indeed. This is also the topic of the upcoming Summer ALMA conference continuing on the last conference. I'm no patent attorney, and the laws are complicated to say the least.

Thanks - Just curiousity, really. It is always interesting to see what claims have been considered unique by the PTO, especially with something like a loudspeaker. One cannot patent the motor, the conical horn, the crossover, the multiplicity of drivers used, or the splitting of signals to facilitate phasing between them. So even if a guy were to find a better way to do these things, there would still need to be something else claimed for the PTO to issue a patent. It would be interesting for me to see which one was used.

I'll go through the points you mention in order... The type or style of motor used in the drive units is inconsequential so long as drive units of suitable electroacoustic parameters is used. The conical horn is not claimed to be unique, but rather is one horn flare type with which this can be employed, and happens to be the one we chose to implement in our products for a variety of reasons. A crossover is not claimed as unique, but rather that a proper crossover will result in flat frequency and phase response at and through the crossover point. The configuration of the design acknowledges the requirement of a crossover for the multi-way speaker and the resulting effects of the crossover. The physical location of the drivers, and the inherent group delay in the crossover makes for a time correct system. The fact that mulitple drivers are used is nothing new to loudspeakers. A means and method by which these drivers operate as one coherent source in this manner is unique. The phasing which occurs as the signals are split occurs in any conventional system. This configuration recognizes that and takes advantage of the situation.

We aren't really finding a "better" way to do the same thing, but rather finding a way to do what can't be accomplished by conventional means or methods. Realize that the process of application examines each claim, and each must be proven to be unique. They aim to ensure the applicant edits and removes any claims which are not found to be unique. I don't see where one of the claims would allow other, non-unique claims to be patented.

Below is a link to the rear view of our TD-1, which is a 3 way embodiment of this patent.
