The statement that patent details are changed every day is rubish. Most patents remain as issued for their entire term. Certificates of correction are for correcting typographical errors and the like. Re-examinations, as the name implies are the result of having the USPTO take another look at the patent in view of some prior art not previously found. A patent owner will sometimes do this to strengthen their patent prior to litigation. Reissues of patents are possible as well, but are to correct some error that makes the patent ineffective in some way, e.g. claiming too much or too little. For the first two years after issuing, claims in a patent can be broadened through reissue. After that, claims can only be narrowed.

Any changes to the claims after a patent application has been filed must be supported by the patent specification as filed. If one has an application on file and wants to add new information (new matter in patent language) this can be done in the U.S. through filing a continuation-in-part (CIP)application. The details of the CIP application are kept secret unless the application is subject to the new publication provisions. So one is not able to obtain information about patent applications, except through their publication.

As of right now, only the 5,803,827 patent is showing up on the databases. If NG have filed a completely new application, or filed a CIP prior to the Sept. 8, 1998 issue date of their '827 patent, you won't see anything about it until it issues, unless they request publication.

Having said all that, it would be really nice to see some useful tips on NG rather than debates on extraneous subjects. Or is the NG swing just so darn simple there really isn't anything to discuss.
