Space Systems/Loral v. Viasat et. al.
Official Complaint for Patent Infringement in Civil Action No. 3:12-cv-00874-MMA-WVG: Space Systems/Loral, Inc. v. Viasat, Inc. et. al. Filed in U.S. District Court for the Southern District of California, the Hon. Michael M. Anello presiding. See http://news.priorsmart.com/-l5RR for more info.

In 2009, ViaSat acquired WildBlue Communications, Inc. (WildBlue), which had previously purchased the WildBlue-1 satellite from SS/L. WildBlue subsequently changed its name to ViaSat Communications, Inc. So, ViaSat currently owns two SS/L manufactured satellites.
selectively disabling use of non-geostationary spectrum to avoid an interference condition.
These patents are both invalid and not nearly as broad as ViaSat claims.
Multibeam satellites, such as ViaSat-1, achieve their high throughput by reusing the same spectrum many times. So the main source of signal degradation is I or interference, much of which is self-generated, rather than N or thermal noise, which is the main source of degradation in simpler satellite systems. The term C/I refers to the Carrier to Interference, or Signal to Interference ratio.

commercial satellites in the world. SS/L designs and manufactures satellite systems for an international roster of commercial and government customers. SS/Ls customers use its systems to deliver services such as fixed satellite services, direct-to-home broadcasting, mobile satellite services, broadband data distribution, wireless telephony, digital radio, digital mobile broadcasting, military communications, weather monitoring, and air traffic management.
typically request full coverage of the contiguous United States (CONUS coverage) in order to address the full U.S. market. This results in capacity limitations, as the available power would be spread over a large area and channels could not be re-used between users and gateways. In contrast, an operator that already owns or leases another satellite and already provides full CONUS coverage may elect partial CONUS coverage focused on more densely G/T or Gain to Temperature ratio is the standard measure of satellite uplink reception sensitivity.
EIRP or Equivalent Isotropic Radiated Power (aka Effective Isotropic Radiated Power) is the standard measure of downlink radiated power.
Carrier to (Noise plus Interference) ratio is the standard measure of link quality. Both thermal noise and externally-generated or self-generated interference degrade link performance and thus determine system throughput. See further discussion in paragraph 24.
Full CONUS coverage works against high capacity for two reasons. First, the available power must be spread across a large area, resulting in signal degradation (the N term described above would become dominant, as C is reduced). Second, unless the operator is able to locate the gateway terminals outside of the United States (which raises regulatory issues) it means that the gateways and user terminals must share spectrum, further reducing the capacity.
WildBlue-1 was not designed to maximize capacity. SS/L had at the time it built WildBlue-1 already manufactured a satellite with five times the capacity of WildBlue-1 with different geographic coverage and spectrum requirements.

ViaSat also claims that it has patented these design concepts.
SS/L continues to investigate the extent to which ViaSat improperly claimed SS/Ls ideas as its own in its patent applications, and reserves the right to amend this complaint following that investigation.
interference, satellite designers developed several techniques to address the new rules. One obvious solution was to have satellites that utilize both GSO and NGSO spectrum switch off the use of NGSO spectrum during periods of interference while continuing to operate on GSO spectrum. In 1997, for example, Lockheed Martin filed an FCC application for the Astrolink-Phase II system9 that used this very technology. The FCC application describes: (a) the primary use of GSO spectrum and the secondary use of NGSO spectrum, (b) temporarily ceasing operation of the NGSO spectrum during periods of NGSO interference, and (c) using orbit data provided by the relevant NGSO system operators . . . for accurate prediction of interference events, and thereby determine the times at which cessation of emissions or diversity switching must occur.
