Patent: Another Multi Layer Related Sensor Patent from Canon

Patent: Another Multi Layer Related Sensor Patent from Canon

Below is another patent for a multi-layer related sensor patent from Canon has come to light. This is the third one that has appeared in the last month or so.

Keith over at Northlight breaks it down in a way that’s easy to understand. “The issue addressed, is light of the ‘wrong’ colour being reflected from one layer into another, which reduces the ability of different layers to respond to photons of only a particular range of colours. This has the potential to greatly improve the colour accuracy and fidelity of such stacked sensor designs.

Canon Joins Cooperative Agreement to Reduce Patent Trolls

Canon Joins Cooperative Agreement to Reduce Patent Trolls

Asana, Canon, Dropbox, Google, Newegg and SAP Announce Formation of New Cooperative Patent-Licensing Agreement
 
TOKYO, July 10, 2014—Asana, Canon Inc., Dropbox, Google, Newegg and SAP today announced the formation of the License on Transfer (LOT) Network, a cooperative patent-licensing agreement that will cut down on patent troll litigation and the growing practice of patent privateering.
 
Patent litigation reached an all-time peak last year, with more than 6,000 lawsuits filed. Most of those suits came from non-practicing entities, also known as patent trolls—companies that don’t have a business outside of licensing and litigating patents.
 
More than 70 percent of the patents used by trolls come from still-operating companies. Indeed, in a growing trend called privateering, companies are selling patents to trolls that then use those patents to attack other companies. In some cases, those companies arrange to get a cut of revenue generated from the trolls’ suits.
 
The LOT agreement is a new kind of royalty-free cross-license meant to address these growing systemic problems. Member companies receive a license when the patents are transferred out of the LOT group. That means that companies retain their right to enforce a patent so long as they retain ownership of it. However, as soon as it is sold, a license to the other members becomes effective, protecting them from attacks by the troll to which the patent was sold.

 The agreement includes several other provisions that preserve a patent portfolio’s value, including carve-outs for certain M&A transactions and change of control.
 
The initial members of the LOT Network range from early-stage startups to established technology companies. Together they own almost 300,000 patent assets, generate more than $117 billion in revenue and employ more than 310,000 people.
 
“The LOT Network is a sort of arms control for the patent world,” said Allen Lo, deputy general counsel for patents at Google. “By working together, we can cut down on patent litigation, allowing us to focus instead on building great products.”
 
“Startups need to overcome many risks before they can become mature, thriving companies. The LOT Network is a powerful and creative new idea that will help ensure that patent abuse need not be one of them,” said Dustin Moskovitz, cofounder of teamwork software provider Asana.
 
“The LOT Network provides a unique mechanism for reducing patent troll threats while maintaining a portfolio’s primary significance and value,” said Kenichi Nagasawa, director and group executive of Canon Inc.’s Corporate Intellectual Property & Legal Headquarters. “Through the further expansion of the LOT Network, I look forward to the patent system restoring its sound functionality.”
 
“We believe that patents should never be used to stifle innovation,” said Brett Alten, IP counsel at Dropbox, “The LOT network is a creative solution to fight patent abuse that becomes more effective with each company that joins. The more participants there are, the better off we’ll all be.”
 
“Newegg has a very strong history of successfully battling patent trolls, and the License on Transfer Network is another valuable tool that helps protect participants from frivolous patent litigation,” said Soren Mills, chief marketing officer of Newegg North America. “We’re very happy to join forces with Google and other leading technology companies to preserve the spirit of innovation that’s so vital to our collective well-being.”
 
“The structure of the LOT Network helps protect innovative patent owners from unwarranted litigation, without stifling valid, beneficial uses of patents, such as cross-licensing,” said Anthony DiBartolomeo, senior vice president and chief IP counsel at SAP. “As long as a company owns their patent they retain all their rights to it.”

Patent: 1.03x Magnification APS-C Viewfinder

As we get closer to the replacement of the EOS 7D, we’re starting to see some patents that will probably point to some features in the upcoming camera. The recent sensor patent is interesting, as well as this viewfinder patent. We had heard previously about the possibility of a 1.15x magnification viewfinder on the next flagship APS-C camera, which would have been equal to the size of a full frame 100% coverage viewfinder.

This viewfinder is slightly larger than the one on the EOS 7D.

A note about the sensor patent, we have heard that Canon is holding back some sensor patents until the camera is announced to the public, as all patent information is public domain. We’ll see if that turns out to be the case.

Patent: Canon 5 Layer UV, IR, RGB Sensor

A patent showing a 5 layer image sensor from Canon has appeared. UV and IR layers help with color reproduction especially for skin tones.

Keith at Northlight has this to add about the patent: “The pixel structure above, shows a BSI design (back illumination), but obviously no pixel structure. Extending the range of light response to UV and IR would cause issues for current lens designs, but the idea of more than three colour primaries is not new, although it would require a major re-write for support from RAW converter software.”
