AGS diamond-grading system gets three patents
May 23, 2008

Las Vegas—The American Gem Society (AGS) has been granted three U.S. patents, the first in the organization's 74-year history.

The patents, issued by the United States Patent and Trademark Office (USPTO), are all for the AGS' Performance-Based Cut Grading System, which was developed by the AGS Laboratories cut-grade research team after years of work.

The USPTO granted the first patent, No. 7,336,347, on Feb. 26, for computer-ray tracing technology that helps determine a gemstone's light performance. This includes the AGS Performance Grading Software and Angular Spectrum Evaluation Tool (ASET).

The second patent, No. 7,355,683, was granted on April 8, for systems and methods that can determine the dispersion of a diamond relative to an observation point and thereby provide a map or other indicator of the stone's fire potential.

The USPTO granted the third patent, No. 7,372,552, on May 13, for the system and methods AGS developed to illuminate a diamond with multi-angle, color-coded light rays to determine the location from which the gem gathers light.

AGS Executive Director and Chief Executive Officer Ruth Batson said they are thrilled to receive the patents, which are an acknowledgment of the AGS' leadership in the arena of diamond cut-grade technology.

"[AGS Laboratories Executive Director] Peter Yantzer and his team of researchers have worked for several years to ensure the American Gem Society helps provide the trade with better-performing diamonds, and consumers with the confidence they're purchasing the most beautiful diamonds possible within their price point," she said.

So....will this fuel the debate over which is better: AGS or GIA?
 
very good!!!!!

Yes. Specially "The USPTO granted the first patent, No. 7,336,347, on Feb. 26, for computer-ray tracing technology that helps determine a gemstone''s light performance."

BTW. AGS filed this patent in December 2007, but did not give reference for IDCC1 reports :

1) The Stages of Development and Implementation of a Diamond Cut Grading System. S.B. Sivovolenko, Yu.B. Shelementyev, April 2004

2)Diamond Cut Grading System based on 3D model. A Strategy for Development. S.B. Sivovolenko, Yu.B. Shelementyev, April 2004

yea I noticed that...
also
No. 7,372,552 is obvious and has a ton of prior art, but it is fairly narrow so might survive a challenge. It should have been filed as a design patent.

No. 7,355,683 diamcalc has prior art with multiple rays from eye and in the lighting maps and etas.

Most people here on PS probably realize that Serg has been conducting research using mathematical ray tracing with regards to how it may be used to judge and improve diamond design in the form of his Octonus Diam Calc program, however it makes sense that other projects of a similar nature are being conducted at the same time and no doubt there will be numerous patents filed for similar but slightly different variations of the concept - "the space race is on" comes to mind

I know that the concept of mathematical ray tracing has been around for quite some time, I believe that Marty Haske ("Adamas" here on PS) was working on it back in the 60's with Lockheed (?) and I suppose that one could venture that Marcel Tolkowsky used a simpler form of mathematical ray tracing when he conducted his diamond design on a chalkboard (or whatever it was). No doubt we will continue to see many important contributions and variations of this type of work over the next few years, I'm excited to see it because I believe that the information provided by this type of research will benefit our industry and consumers!

Special thanks to all of the people who work on this kind of stuff, because it's (well) beyond the realm of my creativity and talent

The problem with bad patents is that they hurt research rather than help.
Who wants to share anything if someone is going to patent it and potentially not allow you to use your own idea?
Same with patents that are too wide.
While it may not be a problem for ags to have these patents as they have soft chin in the public relations department what often happens to bad patents is they get sold to patent trolls.
The trolls add nothing to anything and head to Texas and start filing lawsuits.
That hurts everyone.

I''ll stay out of the validity of patents discussion since I''m not a patent attorney, but I''m excited about the research regardless of who created what / when because the information and technology is beneficial as a whole.

Todd,

There are big difference between just raytracing approach to find best combination parameters and grade real diamond using scanned 3d model
We introduces approach for grading diamond with using scanned model on IDCC1 in beginning 2004. ( we explained why it is much better than parametrical approach : previous AGS grading system and current grading system from other Labs)
We did not fill patent and did reports on conference to keep door open for other companies.
but in end 2004 AGS filled patents
AGS delegation was present on IDCC1.
AGS did not do any links in Patent application to our reports on conference.( It is not allow patented what had been published)

I''m not defending the AGS or challenging you Serg, I merely posted the article from National Jeweler pertaining to the AGS being awarded patent status because I thought it would be interesting for people here on PS. Whatever occurred behind the scenes is not something that I am privy to. I hope you understand that I''m not choosing sides, we use your software, we rely on lab reports issued by the AGS, if you feel you have been wronged by the filing you should challenge it; or at the very least discuss the matter with Peter Yantzer over at the AGS directly since there is little that anybody here on PS can actually do about it.
 
One more

Ray tracing method for evaluating optical property of gemstone,

involves propagating selected ray and creating subsequent ordered path set,
and determining optical property of gemstone based on analysis of selected rays.

Patent Number(s): WO2008066937-A1
Inventor(s): FLATT J, QUICK J, SASIAN J
Patent Assignee(s) and Codes(s):AMERICAN GEM SOC (AMGE-Non-standard)
 
I just searched the document for MSU, OctoNus and DiamCalc and came up with no mention.
AGS are trying to find ways to number crunch faster - OctoNus have been doing that for 10 years.

I think Sergey you are concerned that AGS are attempting to narrow the field where as you have openly published and not patented your work which preceeded that of AGS.

I tried to find a link to the patent - anyone a better searcher than me (not hard).

GemCad and DiamCalc and Marty''s ray trace software are prior art for this patent big time.
 
Thanks Storm,

In the section on prior inventions it seems the AGS lawyers have deliberately left out all the relevant work you mentioned except the one thing the USPTO examiners would easily find – Shannon, and even that is referred to obliquely as United States Patent No. 5,966,673. It is, as Sergey has pointed out, rather disappointing.
Here are a few exerpts that show what I mean.

2. DESCRIPTION OF THE RELATED ART
0008] Gemstone complexity has led to the development of systems, methods, and apparatus, which can evaluate the characteristics of light passing through a diamond using computer modeling. Generally, the computer will trace the paths of a large number of hypothetical light rays through a representation (a skin or model) of the gemstone utilizing ray tracing algorithms. This tracing relies on mathematic and physical rules to evaluate what a user will see when the gemstone is exposed to general environmental light. Ray tracing is performed by company proprietary software or with commercially available optical design programs such as ASAP™ (available from Breault Research Organization, Tucson, AZ), FRED (available from Photon Engineering, Tucson, AZ), LightTools® (available from Optical Research Associates, Pasadena, CA), TRACEPRO® (available from Lambda Research, Littleton, MA) or ZEMAX® (available from ZEMAX Development Corporation, San Diego, CA)

[0009] Some of these systems and methods are shown in United States Patent Applications Ser. No.: 11/018,042, 11/018, 743, 11/018,742, 11/018,744, and 11/388,384, the entire disclosures of which are herein incorporated by reference. These Applications provide for a number of systems, methods, and apparatuses which utilize ray tracing to evaluate diamonds and other gemstones. These applications generally provide for systems, methods, and apparatus that utilize ray tracing through a three-dimensional map (or skin) of a diamond. The ray tracing will generally be performed by a computer or other processor which will trace a large number of rays through the gemstone and provide a map or other visualization which graphically shows how light rays of various different wavelengths interact with the gemstone'' s shape. The systems methods and apparatus may also provide for numerical indicators of a particular diamond''s ability to provide a particular optical feature.

[0013] One patented method attempts to deal with this computational intensity by decreasing the computations involved in the analysis. Instead of ray tracing, United States Patent No. 5,966,673 describes a method that models the propagation through a gemstone of a three-dimensional light beam. Because a beam has a definite cross-sectional area, this method covers more of the gemstone surface with each beam propagation than does any single ray propagation. In ray tracing of gemstones, however, the value and accuracy, as well as the different types of information that can be provided, is often increased by simply increasing the number of rays that are traced. Therefore, it is often preferable to model the propagation of a large number of rays. Thus, too, it is often preferable to utilize a more efficient ray propagation method.

For the record, the beam hits the diamond surface as a discreet point – it does not ‘cover more of the gemstone surface’.
