Hello all, been out of the loop for a while but back now.
You have a very good topic but I think it may go a little deeper than that. If a manufacturer sells a product that they nowingly are infringing on a patent, I dont think the end user is liable. What is of more concern is breaking spec with inferior products or its on the shelf mentality or even its cheaper and I dont care how long it lasts.
What do you think the ramafications should be if a sign shop is doing a national account , reffered project or even an art piece that a manufacturer worked on the specification for months maybe even a year and then the product salesman visits and the specifications are broken. be it power supply, fixtures brand of lamps ect.
I think that is a bigger issue than patent infringment.
Honestly when I have confronted customers about this the reaction I get is "oh well, you caught me" or "I didnt want to by more because I had this already" or even a better one was " this is so much cheaper and this is the oly way I was able to get the job" These comments are from large well known reputable shops. I personally think copy right infringement is the last thing on thier mind unless they are phisically doing the infringement and marketing the product as thier own private label.
