Although the various embodiments of configuration aids in accordance with the present invention were described with reference to geometrical shapes and colored surfaces those skilled in the art will appreciate that numerous other embodiments are also possible For example the configuration aid may comprise any lettering numbering symbol or the like that allows a user to distinguish between the first and second sides of an electronic connector Furthermore the configuration aid may be marked on the cormector with any suitable marking means such as by printing painting dying inscription adhesive or the like.
Gosh, I wonder if one could use a USB logo for this? Too bad the USB specification doesn't tell you where to put it. Oh wait, it actually does (see section 6.5.1 of the USB 2.0 specification or simply consult the FAQ)!
This joker wants three and a half million dollars for the right to mark one side of a polarized connector differently than the other. He actually uses the USB connector as a case study and example in both patents. That is, the very same specification of what he is using as an example in both of these patents specifies the prior art which should have properly invalidated these patents: it requires putting the USB logo on the top side and not on the underside. Both patents, US 8,142,220 & US 20,110,165,792, seem to be referring to the same concept (I assume there must be some legal reason for this).
I can only assume that the patent examiner(s) never used a USB connector and could not be bothered to do a few Google searches."
