*Almost all of the issued patents listed above were filed and prosecuted exclusively by Doug Weller. The remainder of the cases were originally prepared and filed by Doug Weller, but some or all of the prosecution was handled by another, or were filed by another and some or all of the prosecution was performed by Doug Weller. This is only a partial list assembled in 2009 by Doug Weller. The case files of patent applications belong to clients which can complicate the process of finding patents that were worked on over a 25+ year career. Many of these patents were for Hewlett-Packard Company and their spin-offs such as Agilent, that did not usually list the names of outside Attorneys or Law Firms on their issued patents.
