IP Portfolio

In 2007 PowerbyProxi negotiated an exclusive agreement with UniServices (the commercialization arm of The University of Auckland) to licence a number of key patents based on the concept of Dynamic Tuning in a wide range of key markets.  This agreement is ongoing and includes licenses in key industrial segments and for miniaturized applications in the Consumer Electronic Device market.

Our partnership with UniServices (who are also a shareholder in PowerbyProxi) gives us an in-depth knowledge of the IP landscape and prior art that has been published in wireless power.

We presently have a comprehensive portfolio of over 333 patent rights worldwide, including the published patent rights below:
