POET’s GaAs patents

The number of patents continues to grow. This is not really what I expected. Based on early comments by Suresh (beginning of 2016) there were approximately 40 patents (in total between applied for and issued). It is expensive to maintain a large number of patents and one of the goals was to review all the patents and identify the seminal patents required to support those that they felt would represent a market application that they had plans to persue.
58 patents show up in the USPTO patent data based (which does not include the most recent patent "DUAL WAVELENGTH IMAGING CELL ARRAY INTEGRATED CIRCUIT")
When we begin to look at some of these patents we can see applications that are now becoming relevant to the market as early first generations of these technologies that are now being employed.
I think it would be reasonable to consider that as POET becomes developed in a more dedicated manner in a facility where they are not competing for space or position in a que that they will begin to have an opportunity to consider new applications that were not part of the early focus by this management.
Example:
Thz detection employing modulation doped quantum well device structures. This patent was filed in 2003 and issued in 2007.
State of the Art
Satellite communication systems are now pushing into the sub-millimeter wave region in the quest for greater data throughput. With the upcoming wireless revolution and the anticipated demand for Internet services from almost anywhere, there will be significant demand for higher frequency carriers and modulation capability commensurate with these bandwidths. For future military terrestrial communication channels, the THz region (100 GHz-10,000 GHz) offers greatly enhanced capability. For satellite/ground and helicopter/ground links it avoids many of the problems of atmospheric scattering and absorption and adverse climatic conditions found in bandwidths up to 300 GHz. In addition, large toxic molecules of biological and chemical agents have resonances in the THz region and the detection of certain (chemical) weapons and explosives would be enabled. Furthermore, standoff detection (which involves passive and active methods for sensing of chemical and biological material when the sensor is physically separated from the site of interest) could be achieved by monolithic integration of a detector of electromagnetic radiation in the THz region (100 GHz-10,000 GHz), referred to herein as a THz detector, with data processing circuits providing a rugged, compact and portable sensor offering critical human protection.
