As I read this document it is a patent application. No patent has been granted 
and there is a period of evaluation during which it is easy to challenge. If it 
is ever granted then it could be a real nuisance. 

I filed a UK provisional patent 27th October 2006 referring specifically to 
silica..
My first article in any press was a regional weekly newspaper on1st DEc 2006
I had article in the magazine of the Ski Club of Great Britain specifically 
mentioning silica in January 2007 in my website://  
www.naturaljointmobility.info/pressarticles.htm 

All of that was before I had ever heard of the word geoengineering or this 
group. Only later did I find out about Greg Benford's work -and other similar 
work.Prior to that I thought my work was original as possibly Mr Neff thinks! 

Can someone in a US university with a patent department investigate and put a 
challenge in before its too late. I will provide details of the above three 
bits of evidence.

  James Cascio has kindly pointed out that a patent has been issued for the use 
of silica particles for stratospheric sunshade geoengineering. (see attached).

  The patent was filed on 30 Sep 2009, with a provisional patent filed on 30 
Sep 2008. I note that this idea of using silica particles was discussed on this 
group at least as early as 1 May 2007:  
https://mail.google.com/mail/?shva=1#search/googlegroups+silica/11243cfe473291d8

  and I have email from Greg Benford from that period specifically referring to 
"diatomaceous earth".

  One would assume that any rational court would find that this patent 
describes things that are obvious to those skilled in the relevant arts. (I 
suppose the question then is whether an expectation of encountering a "rational 
court" is itself rational.)
