Hi all, We're 1/2 thinking about doing some entangled photon experiments.
A colleague told me that he thought there was a patent on the source of
the photons (from Los Alamos labs, he thinks) It very well may be from
this paper, http://www2.optics.rochester.edu/workgroups/lukishova/QuantumOpticsLab/homepage/type_i_kwiat_physrev_99.pdf
How would you go about finding such a patent?.. if it exists.
Thanks,
George H.

Never mind, I searched under first authors name and found it here. https://patents.justia.com/patent/6424665
So when does a patent expire?

Seventeen years after date of filing (used to be date of grant, but no longer).
Nor is it first to invent anuy more - now, it’s first to file.
These two changes stopped a lot of games.

No, it is 20 years from the date of filing. I believe when that patent issued, there was also the stipulation of 17 years after the date of issue, whichever is later. Now it is always 20 after the date of filing.to be valid. You still have a 1 year after public disclosure (but no offer for sale) if you only want to file in the US.
Also, a key distinction in the first to file rule. US patents are first inventor to file. This means that non-inventors cannot file for a patent. Their patent would be invalid if they did. An inventor must be named on the application for the patent

Thanks Dan, Joe. I took this discussion over the SED where I got
basically the same answers.
