Enertechnos granted patent by US Patent Office

5th November 2021 — The US Patent Office has granted our new patent on the capacitive transfer cable (CTS). Furthermore, notification was received a few days ago from the Patents Directorate of the UK Intellectual Property Office of ‘Notification of Intent to Grant’ the same patent. We are expecting similar notifications from the European Patent Office imminently.

The reasons that this is such an important development are that, first, the new patent describes in much more detail the way that the CTS works and how it can be made and, second, it establishes a new priority date so that the patent protection runs far longer than the older patents.  The original patent has a priority date of 04.08.2008 (and so is protected for twenty years from then) while the new one has a priority date of 07.06.2018 and so provides protection until 2038. This is in-line with our policy of refreshing patents on a regular cycle to prolong as far as possible the protection that they provide.

 

 

We announced in June that we had filed a patent for the wireless EV charging application of CTS cable. We did further work on this, and it has now been expanded so that it covers a wider range of applications that utilise high frequency. The manner in which we did this means that we have preserved the earliest possible priority date, which was 09.06.2021. The reason for this tactic is that should any ‘bad actor’ try to make an end run by filing a patent of their own for a high frequency distribution circuit before publication of ours, we have additional cover.

Finally, we filed last month amendments to the patent for the protection circuit, which has a priority date of 09.10.20.
