D2P Patent 7,184,723 Analysis

Related Terms:

Multiple analyses of the first published D2P patent ( D2P Patent 7,184,723) finds that neither novelty nor feasibility was demonstrated. In fact, the ideas can only work with “ideal” components and not with components that actually exist in silicon, so that the design as presented can either not be manufactured, or will not perform as specified.

Since these analyses were first done (the first versions were done in early 2007), we have discovered that, in fact, ParkerVision was unable to make a chip work based on patent 7,184,723. The chip had significantly less output than ParkerVision predicted and was, in fact, fairly inefficient. Apparently ParkerVision has discovered this in 2005, and has been attempting to "patch" the idea with new provisional applications.

 

One professor of Electrical Engineering has stated, upon review of the patent:

  • The parts of the patent that describe functioning elements are not novel.
  • What is novel doesn’t work
  • The inexperience of the ParkerVision team is evident not only in naiveté of the proposed approach, but also in their inability to discover the underlying flaws, despite what is clearly a large effort.
  • If they did discover their flaws in the course of the work, their lack of candor in acknowledging them is in itself problematic, particularly in view of past published allegations of fraudulent claims.
