An interesting thread.
I agree with Jensen protecting its IP. Any patents probably expired years ago (I did a Google Patent Search and didn't find any), but Jensen certainly has the right to protect its trademarks and copyrights.
I suspect that the designer will be receiving a Cease & Desist letter soon. I am not sure why they don't pursue royalty agreements with other builders or joint ventures.
What I worry about with Jensen is that they have lost their "thirst for innovation" and they don't seem to have any interest in anything new (which is usually a death sentence for most family owned businesses).
I feel like we are watching the founder's legacy whither away with the second/third generation (which is not uncommon with family owned businesses which rarely are successful beyond the Founder/Patriarch).
I hope I am wrong. They have a loyal fan base here, for sure.
