The patent
https://www.google.com.au/patents/U...ved=0ahUKEwi2s9Sb6sXRAhWBk5QKHSDCCTsQ6AEIGTAA
10. A method for operating ametal detector of a type which includes the ability to select values of operating parameters and to store such values as data, the method including the steps of:
a. receiving operating parameter data via an electronic transmission link from a data source external to the metal detector, the operating parameter data being a set of values of operating parameters,
b. storing the operating parameter data in an electronic memory within the metal detector, and
c. modifying the operating parameters of the metal detector to conform to the set of values of operating parameters specified by the operating parameter data, wherein the electronic transmission link includes a wireless connection transmitting through space between the metal detector and the external data source.
Not sure how a wireless connection between electronic and/or data is a defensible patent. Does this mean that other detectors with wireless headphones are in violation? That is data transfer through a wireless connection. (love the lack of
spell check in the patent!)
Seems like many detectors can download the stored data to a computer, with a cable and/or wireless.
So Deus has a detector that has a wireless coil, headphones, etc., that they also state is patented...
The lawsuit:
https://search.rpxcorp.com/litigation_documents/12198420
12. XP and Detector are contributorily infringing and inducing the infringement of at least claim 10 of the ’586 patent. XP and Detector will continue to infringe the ’586 patent unless enjoined by this Court.
13. XP is manufacturing, using, selling and/or offering to sell the DEUS metal detector which can be operated in a manner where data stored in the metal detector can be modified by data stored in an external source. XP advertises its DEUS product with specific instructions for its customers to operate the DEUS product in a manner that infringes at least claim 10 of the ’586 patent.
The real issue... the use of a wireless headset! and the use of a remote control!
..
.."For example, XP and Detector have been and continue to actively induce this infringing activity by encouraging and instructing customers to use the DEUS headset and remote control features so as to directly infringe the ’586 patent. By encouraging and instructing its customers to do so knowing that this use will directly infringe the ’586 patent, or remaining willfully blind to this fact, XP and Detector specifically intend to cause direct infringement of the ’586 patent...."
So it is the use of a wireless headset?!?!?! About a remote on/off switch....hmmmm, a bit of a stretch...
since the entire detector is wireless, would have to see the patent they were issued to see what governs, especially with filing dates...as ML has the US 7310586 B2 (2007) (which added wired/wireless data transfer) , but also registered it as US 20050062476 A1 (2005)
in effect, ML only states that it has infringed, but gives little specifics on what feature(s) in the XP detector infringe, just blanket statements. This is interesting in my opinion. It appears that ML sent the warning back in early 2016, so perhaps XP decided it was not really an issue...lawsuit, well...
(A jury trial on a patent case, oh the drama!)
EDIT:
Also named is as a defendant is DEC,
