Hi, I have a question regarding patent infringement. I will describe the situation as briefly as I can. I designed and manufactured a product for which I was granted a full standard patent. I sold my product to one customer only. A few months later, the customer stopped buying my product and went very quiet despite knowing they had a need to purchase my product. I later found out that an individual contracting to the customer started to produce (and has sold) a similar product at a lower price. I believe the product will infringe my patent as there are very specific features that it would require to be functional. My question, how do I obtain a sample of the offending product in order to have a lawyer analyse and confirm patent infringement when it is not commercially available?
