Recently, I’ve been keeping my eye on a site I found that shows the patents published by companies in Japan. It’s easy to see the camera-related patents because Ricoh Imaging is listed separately from Ricoh overall. I know that these patents are not necessarily a clear indication of what products Ricoh will come out with. Nevertheless, I thought it was interesting to see the volume and type of patents they are applying for. It’s an interesting counterpoint to the assertions that Ricoh Imaging is not working on anything.
Here is link to Ricoh Imaging (Japanese):
???????????????????? 2017?
In terms of volume, the trend is that number of patents published by Ricoh Imaging has increased year on year.
2014 - 87; 2015 - 125; 2016 - 132; 2017 - 130 (to Oct 12, so you can project that they’ll be over 150 for the whole year)
Trying to look at the content of the patents is quite difficult, because of the technical nature of the descriptions, the language problem and the fact that the images don’t always show up properly, for me at least. From what I can understand, Ricoh has been working on a number of areas.
- There are a lot of patents related to the prism and mirror set up. It seems that research is focused on DSLRs.
- There are numerous patents related to sensors, such as on-sensor AF, reducing rolling shutter effects and so on, which might indicate something new for Ricoh.
- There are several about lens motors and casings.
- Of the optical designs, most are zooms.
The site also shows a patent ranking of all companies, and I was surprised to see Ricoh (overall, not imaging) in 6th position, keeping company with some very big corporations. I think this indicates that it is quite a research focused company. Interestingly, Canon is top of all companies, but again this is the group as a whole, not particularly the camera division.
