Pitham Vision

Patent-family assignee (listed as “Pitham Vision”, 皮修姆视觉公司, on Google Patents) for a set of European-origin filings covering a wearable optical projection system for photosensitive (“corrected”) retinas — the optics hardware that accompanies a photovoltaic subretinal implant or optogenetically modified retina.

Key facts

• Holds a patent family with priority 2019-03-28 (PCT/EP2019/057965), filed 2020-03-27 (PCT/EP2020/058873), with members in WO, EP, US, CN, CA, AU, JP.
• Three related publications identified (all priority 2019-03-28, filed 2020-03-27):
  • CN113677257A — System for projecting a pattern of interest onto a retinal area of a human eye (inventors Guillaume Buck, Xavier Beuque, Vincent Bismuth, Martin Deterre); US member US20220192885A1 (active).
  • CN113613712A — Device, projector device and method for projecting a light beam onto the retina of a human eye (inventor Martin Deterre).
  • CN113631079A — Method and apparatus for projecting a target pattern on a modified retinal region (inventor list per CN record includes Martin Deterre and three co-inventors).
• Status per family (as of 2026-09): family 1 (CN113677257A): CN/EP/CA pending, US (17/593,274)/AU/JP active; family 2 (CN113613712A): US (17/593,276 + continuation 19/210,450, 2025)/JP active, AU abandoned, CN/EP/CA pending; family 3 (CN113631079A): CN granted (CN113631079B), US (17/593,275 + continuation 18/796,038, 2024)/JP/AU active, CA/EP pending; the priority WO applications of all three families are ceased.

Scope and positioning

The patent claims describe glasses-like headwear with a camera, a pulsed near-infrared/DMD projector, and a fibre-linked pocket processor — i.e., the “camera glasses” half of a photovoltaic retinal prosthesis, in the same architectural family as the science-corp PRIMA system (subretinal photovoltaic implant + projection glasses). See visual-prosthesis-patents for per-patent summaries; see retinal-prosthesis for the technology category. Adjacent-but-distinct: azalea-vision’s smart contact lens corrects optics rather than replacing photoreceptor function.
