    Patent-Trolls Never Get Tired! *LOL*

    Hi all,

    have a look at this trivial coil patent.
    US20130307531A1 - Search Coil Assembly and System for Metal Detection - Google Patents
    https://www.google.com/patents/US20130307531?dq=20130307531
    A search coil assembly comprises a transmit coil operable for radiating a magnetic field in response to a time varying current. The transmit coil comprises a conductive path being disposed at least within a transmit plane for radiating the magnetic field. At least one receive coil is operable for inducting a current in response to a time varying magnetic field. The receive coil comprises a conductive path being disposed within a receive plane for inducting the current. The receive coil is positionable to place the receive plane and the transmit plane in a substantially orthogonal orientation with the receive plane being substantially within null regions of the transmit coil's magnetic field, in which a metallic object, at a distance from the search coil assembly, reacts to a radiated magnetic field from the transmit coil, and the receive coil inducts a current in response to the reaction.

    Inventor need not worry, no one will replicate such design. His patent will last forever.

      Mr. Nel is apparently 110 years late:

        Yep and patent examiners are sleeping at work.

          ... the ore finder is only an XY coil configuration ... dont knock it though ... I have found many nuggets with my model 1905.

          There is also a great deal of difference between posting on forums and publishing patents ....

            The patent in question should have not been granted.
            - pior art
            - lack of inventive ingenuity (so trivial)
            It's pure waste of money. Comeon!, let's infringe this patent! *LOL*

              .... true ... however there are very few actual inventions patented nowadays.

                Infringing? If it involves dressing as sharp as the chap from 1904 holding that "ore detector device" then why not! Also, that horn earphone might be pretty battery-effective with a ceramic driver.
