Greg Johnson is indeed the inventor of the antenna technogy patent that was sold by publicly owned Aerius International, INC to privately-owned Delaware corporation Aerius Intenational, LTD in November 2009. I believe Johnson may be one of the owners of the private DE corporation
Assignment #2 shows that the patent was assigned from Aerius International, Inc. to Aerius International, Ltd. on 11/23/09 which was recorded on 1/12/10:
Interestingly, this is a newer patent. A provisional application was made for this patent 8/27/07 (establishing a priority date) with the full application filed on 8/27/08. The patent was issued on 12/28/2010 after it was assigned to the private corporation.
Bill Luxon's 6 previous patents, the last two of which Johnson was a co-inventor, all relied on an extension type antenna. The two Johnson co-invented were assigned to RangeStar Wireless, Inc. -- a company co-founded by Johnson and Luxon and later sold to Tyco.
Greg Johnson was the CTO of AERS when Luxon was the CEO. The two seem joined at the hip. Certainly Johnson was aware of all of the false and misleading claims made by AERS after the patent was reassigned to the private Aerius LTD corporation.
