Stark, C. J. Claim construction opinion issues regarding seventeen terms from five patents. A Markman hearing took place on April 4, 2016.

The disputed technology relates to cell phone communication technology. The following terms were considered:

  1. “identifying changes in signal drop-out characteristics”
  2. “encoding packets into packet blocks”
  3. “encoder for combining and varying the number of packets transmitted in each of the packet blocks”
  4. “frequency hopping”
  5. “a structure for allocating ones of baseband outputs from a digital channelizer to ones o logical inputs of digital signal processors and allocating ones of baseband inputs of a digital combiner to ones of logical outputs of said digital signal processors according to said mapping signal”
  6. “allocating resources”/ “allocating bandwidth resource” / “allocates resources”
  7. “application aware resource allocator at the MAC layer” / “application-aware media access control (MAC) layer”
  8. “a module operative to recognize an application type of said software application associated with IP flow” / “ identifying means for identifying an application type of a software application associated with an IP flow”
  9. “allocating means for allocating resources to said IP flow…so as to optimize end user application IP QoS requirement of said software application”
  10. “allocating a proportion of said total number of data packets to a number of the tiers of service to allow individual packet data queues on a number of tires to share a communication resource”
  11. “means for allocating a tier of service for each of a plurality of individual packet data queues, wherein the means for allocating allocates different weights to each tier of service based on a number of user requiring access to the available communication resource”
  12. “means for determining a total number of data packets that can use a n available communication resource”
  13. “Scheduling means to provide said communication resource to queued packet data users on a tier-by-tier basis, such that said resource is made available to all users”
  14. “means ... for allocating a proportion of said total number of data packets to a number of the users of service to allow individual packet data queues on a number of tiers to share a communication resource"
  15. “primary preamble sufficient to enable radio operations”
  16. “an autocorrelation having a large correlation peak with respect to side lobes; a cross or relation with other primary preambles having small cross-correlation coefficient with respect to power of other primary preambles; and small peak-to average ratio; and wherein a large number of primary preamble sequences exhibit the properties”
  17. “wherein the core-band is substantially centered at an operation center frequency
