In reference to the patent: EP3118774A1
I am working in the same field, and it seems to me that this patent is similar to a technology already existing since 2001. developed by HP: http://www.hpl.hp.com/research/ptm/ . Later developed also by other groups, maybe notably http://vcg.isti.cnr.it/rti/acquisition.php . It has been used specifically on books (https://lichfield.as.uky.edu/st-chad-gospels/rti).
What does this patent means? That no one will be able to use an old technology because someone 15 years later patented it? is this possible?
