Mr. Jason May, Director of Operations for Advanced Communications Technologies (Aust) posted the following information regarding QCOM and patents.
We hope this helps.

Response to SC issues from Jason May.
Hello everyone,
It has been a while since my last post, and whilst we have been very busy, a lot of our work lately has remained hidden from public disclosure. I will attempt to address some of the issues raised on the RB board over the past few weeks in this post, but unfortunately some of the questions posed can not be answered publicly because of the sensitive nature of such information. Those of you familiar with the patent process will understand that we enter an 18 month examination period for all of our patents in which we can not publicly disclose details of the patents, for fear of jeopardising their granting.
Patents
We have recently filed the first in a series of patents relating to SpectruCell. This first patent relates to the way in which we generate the CDMA longcodes. This, and for the most part all of our patents, revolve around the software implementation of such systems and functions as related to cellular communications systems. You can only patent something that you can show a creative or inventive process in and also show the implementation. In order for us to progress as far as we have with SpectruCell we have had to develop our own unique ways of implementing GSM and CDMA functions in a software environment. This is what our patents are all about, the software based implementation of cellular systems utilising a software defined radio platform.
Qualcomm
There has been a lot of discussion about the SpectruCell implementation of CDMA without the need for Qualcomm chipsets. To clarify things a bit, Qualcomm does not own CDMA, it owns a specific hardware based implementation of CDMA. This is the IS-95 specification. The origins of CDMA lie in a military background and even further back to spread spectrum techniques developed by Hedi Lamarr in the 1940’s and 1950’s.
What ACT has done is to develop an implementation of CDMA (IS-95) that does not use any Qualcomm chipsets. From legal advice and information received during discussions and meetings with Qualcomm, it would seem evident that we do not need any Qualcomm licensing to develop commercial SpectruCell systems. In the IS-95 specification there are some minor functions that Qualcomm have developed, such as pilot channel synchronisation with the handset, that may need minimal licensing. But this is by far the minimal portion and has no effect on the SpectruCell system.
SpectruCell Competition
Again there is comment about the comparison between ACT’s SpectruCell and Airnet’s Adaptacell. I have responded to this in the past, but the key points are that Airnet is aiming purely at the GSM marketplace. The software radio aspect of the Adaptacell product is mainly for tailoring GSM functionality. The Adaptacell product uses protocol specific hardware, and has no scope for upgrading to multiple protocol support. This is in essence a hybrid software radio, using protocol specific hardware. The Adaptacell is focused solely on the GSM marketplace. On the other hand SpectruCell is a pure software defined radio with all of the processing, channelisation, etc done in software with no protocol specific hardware. We have met with Airnet and they have no plan to move into the CDMA arena, let alone other evolving protocols.
Airborne SpectruCell
In relation to the announcement of the Platform Wireless contract I have heard some of the feedback from the board has not been that positive. This surprises me, as we are deploying a commercial application of SpectruCell well ahead of schedule. This deployment initially supports TDMA, but it is still SpectruCell with the capability of being software upgradeable. To the development staff and the team at ACT this contract is a very important step in the development of SpectruCell. It allows us to demonstrate network interoperability and to test SpectruCell in a commercial environment. The contract with Platform Wireless also provides us with the first revenues from SpectruCell. This type of contract has always been in our marketing plan and is a step in the right direction. It in no way deviates from our chosen path. I do not understand any of the bashing comments about this.
Once again I am more than happy to reply to technical issues related to SpectruCell, my email is jason@adcomtech.net and provided the questions do not rely on me disclosing commercially sensitive information I will post the answers on this board.
Thanks,
Jason May – ACT Australia Director of Operations.
