After reading through the PHSColograms info again I am confused on what
their claim actually is. For one thing they state that their process covers
both barrier strip and lenticular screen usage. The wording is so
generalized that ANY process which cuts the images into strips and
interleaves them for viewing with some (any) transparent material between
the interleaved image and EITHER barrier strips or lenticulars is covered
under their patent!!!
If anyone here has more specific knowledge as to the limits of their claims
I would appreciate hearing those details. The presentation they make seems
to cover too many bases. I learned a whole lot about 3D images, lenticulars
and barrier strips without once hearing about this company and it's apparent
claim on all of that. It was much later that I came across their pages with
extensive patent claims. How can their claim be valid when so many others
hold patents to a variety of lenticular screens and similar 3D processes?
Have they just overstated their case?
If patents are applicable only to specific items and specific processes, how
can it apply to a process that is a general purpose process and applies to
general usage with a lot more than lenticular or barrier strip 3D? An image
or set of images can be cut into strips with scissors, razor blades, or any
of dozens of common graphics programs. How can they claim rights to such
tools and their usage with common knowledge about lenticular screen physics?
I can understand if they have specific software that is their own optimized
and specific design but not general usage of tools that aren't theirs or
physics knowledge that preceeds their invention.
Any thoughts?
