keep in mind, there are much stronger patent/copyright laws in the US than in Latvia... for example, the copyright law protects the original author for the duration of his lifetime + 70 years after the death of author... patent protects for 20 years from the first registration... same item can be patented and copyrighted...

change design, call it something else, no need to contact anyone - similar to "stealthOne", or Resler ibus reader - those items are used in the car but unique to their authors...
